feat: add provider-aware browser QA setup

Detect host-native browser tools before offering the isolated local Chromium fallback, add a common readiness fixture, harden managed browser startup, and verify standards installs expose one canonical QA skill.

+requires an explicitly installed extension; neither is silently upgraded.
+Inherited host environment variables never count as provider detection. No

+# Browser-provider routing eval — 2026-07-20
+
+## Scope
+
+Report-only evaluation of GStack 2 just-in-time browser-provider selection on
+macOS. No product files, host settings, extensions, browser profiles, or managed
+runtime components were changed. No `./setup` command was run.
+
+The inventory covers the seven installer-verified GStack 2 hosts plus Gemini
+CLI: Claude Code, OpenAI Codex, Kimi Code CLI, Cursor, Pi, OpenClaw, GitHub
+Copilot/VS Code, and Gemini CLI.
+
+## Installation-path reproduction
+
+The reported loaded path was:
+
+```text
+.agents/skills/gstack/qa/SKILL.md
+```
+
+That is the cloned GStack 1 compatibility tree. Its `qa/SKILL.md` still contains
+an instruction to run `cd <SKILL_DIR> && ./setup`. The canonical GStack 2 path is:
+
+```text
+.agents/skills/qa/SKILL.md
+```
+
+The canonical source is `skills/qa/SKILL.md`; it routes browser setup through
+`references/BROWSER-PROVIDERS.md` and explicitly forbids `./setup` in a
+standards-installed skill directory.
+
+## Official provider inventory
+
+| Host | Interactive browser capability | Classification | Setup/readiness constraint |
+|---|---|---|---|
+| Claude Code | Claude in Chrome | Native extension | Chrome extension, paid direct Anthropic plan, site permission, and live connector discovery are required. |
+| OpenAI Codex Desktop | In-app Browser; optional Codex Chrome connection | Native in-app | The in-app browser must be opened and exposed to the active task; CLI presence is not readiness. |
+| Gemini CLI | Experimental bundled browser agent | Native experimental agent | Disabled by default, requires Chrome 144+, one-time consent, and can use isolated, persistent, or existing-browser modes. |
+| Cursor | Chrome DevTools provider was live in the evaluated CLI session | Host-provided MCP | Must be discovered from the current tool surface and pass the common readiness journey. Current public Cursor tool docs do not establish universal availability. |
+| GitHub Copilot / VS Code | Integrated browser agent tools | Native in-app | Browser tools must be enabled in the tool picker and may be controlled by organization policy. Agent-created pages use isolated in-memory state. |
+| OpenClaw | Bundled browser plugin | Native bundled plugin | Plugin/tool policy must expose it; the default managed profile is isolated from the personal profile. |
+| Kimi Code CLI | WebSearch and FetchURL only | No native interactive automation | `kimi web` is the session UI, not an agent-controlled browser. |
+| Pi | No core browser; optional community packages exist | Extension-only | A third-party package install is required and must never be inferred or performed silently. |

+## Provider-selection eval
+
+All runnable agents received the same clean-room prompt, canonical project-local
+QA skill, and fresh `GSTACK_HOME`. The prompt prohibited installation, settings
+changes, extension enablement, profile attachment, consent acceptance, and
+`./setup`.
+
+| Host run | Version | Result | Key evidence |
+|---|---:|---|---|
+| Claude Code | 2.1.214 | PASS | Correctly found no Claude-in-Chrome tool surface, rejected unrelated installed binaries as readiness, and offered native setup, GStack preview/install, evidence-free continuation, or defer. |
+| Codex CLI | 0.144.5 | PASS | Live provider discovery returned no browser in the CLI task; it correctly offered activation of Codex Desktop Browser and the other three choices without installing. |
+| Gemini CLI | 0.51.0 | FAIL | Twice misidentified itself as Codex by reading inherited `CODEX_*`/desktop environment signals. It never inspected a callable Gemini browser tool and omitted Gemini's own experimental browser agent. |
+| Cursor Agent | 2026.07.16-899851b | PASS WITH CONTRACT AMBIGUITY | Discovered a live Chrome DevTools peer and completed functional tests, but initially emitted `currently_usable: true` before the readiness journey had passed. |
+| Pi | 0.80.9 | PASS | Correctly classified the read-only session as no native automation and offered all four choices. |
+| Kimi | 1.49.0 | BLOCKED | Existing credential returned HTTP 401 before the agent could evaluate the skill. |
+| OpenClaw | not installed | UNTESTED LIVE | Official documentation establishes a bundled browser plugin; no local executable was available. |
+| GitHub Copilot / VS Code | VS Code 3.12.17 | UNTESTED LIVE | Official documentation establishes integrated browser tools; the active task did not expose a Copilot agent session. |
+
+The cross-model harness dry-run recognized Claude and Codex but incorrectly
+reported Gemini OAuth as unavailable. The Claude/Codex selection run completed
+without a paid quality judge:
+
+| Model | Latency | Input → output tokens | Estimated cost | Tool calls |
+|---|---:|---:|---:|---:|
+| Claude Opus 4.7 | 69.8 s | 8 → 4,801 | $0.52 | 5 |
+| GPT-5.4 | 43.1 s | 190,996 → 1,398 | $0.49 | 9 |
+
+## Functional public-web eval
+
+Two providers were already available without installation or profile attachment:
+Codex In-app Browser and Cursor's Chrome DevTools provider. Both passed the same
+four journeys:
+
+1. TodoMVC: add a todo, mark it complete, open the Completed filter, and verify
+   retained state plus zero active items.
+2. Selenium Web Form: fill text, choose option Two, check the default checkbox,
+   submit, and verify `Form submitted` plus `Received!`.
+3. The Internet JavaScript Error: capture the deliberate `TypeError` from the
+   console with its source URL.
+4. TodoMVC responsive: emulate 375×812 and capture screenshot evidence.
+
+Both providers also passed the local common-readiness fixture: exact loopback
+navigation, heading read, button interaction, `READY` state, console marker,
+successful `POST /proof`, fixture shutdown, and released listener.
+
+Evidence:
+

+   `.agents/skills/gstack` exposes the legacy compatibility skill and its
+   `./setup` instruction. A clean GStack 2 evaluation must use the standards
+   installer and load `.agents/skills/qa/SKILL.md`.
+2. **P1 provider registry is incomplete:** `BROWSER-PROVIDERS.md` names only
+   Claude, Codex, and Kimi. It is missing Gemini, Cursor/runtime-discovered MCP,
+   GitHub Copilot/VS Code, OpenClaw, and Pi's explicit no-core-browser case.
+3. **P1 host inference is unsafe:** Gemini demonstrated that environment
+   variables inherited from the parent application can identify the wrong host.
+   Provider selection must use active callable tool discovery first.
+4. **P1 readiness state is underspecified:** `available`, `needs-user-action`,
+   and `ready` must be separate states. Cursor called the provider usable before
+   the readiness fixture had run.
+5. **P1 benchmark detection misses Gemini OAuth:** the model benchmark's auth
+   detector disagreed with a successful direct Gemini run.
+6. **P2 no cross-host setup copy:** the user-facing decision should be generated
+   from a common state machine, with host-specific setup text supplied by an
+   internal registry rather than hand-authored branching in each specialist.
+
+## Recommended decision contract
+
+```text
+QA requires an interactive browser.
+
+Detected: <provider> — <ready | needs user action | unavailable>
+
+A) Use the detected agent browser
+B) Preview the isolated GStack browser download, then ask separately to install
+C) Continue without browser evidence (interactive claims will be unverified)
+D) Defer
+```
+
+Selection is not readiness. Readiness is granted only after the common fixture
+proves navigation, page reading, interaction, console/network evidence when
+supported, and clean shutdown. GStack local browser preview and installation
+remain two separate approvals. `./setup` is never a valid GStack 2 response.
+
+## Untested surfaces
+
+- Claude in Chrome functional automation: no extension peer was attached and no
+  permission was granted to attach a signed-in profile.
+- Gemini browser-agent functional automation: enabling it and accepting its
+  first-run consent would change isolated host settings and requires explicit
+  approval.
+- GitHub Copilot/VS Code and OpenClaw live journeys: their agent tool surfaces
+  were not active on this machine.
+- Kimi provider-selection judgment: authentication failed before inference.

At onboarding, offer this flow only when the user asks to configure browser capabilities now. Otherwise run it just in time when a selected workflow first needs interactive browser evidence.
+
+## Routing flow
+
+1. Identify the active host and provider from callable tools in the current session, not from unrelated installed binaries, parent-application environment variables, documentation, or guessed host names. Inherited \`CODEX_*\`, bundle identifiers, and similar process metadata never override the actual agent/tool surface.
+2. Show the detected provider, what user-controlled setup it requires, and the GStack local-browser fallback.
+3. Ask whether to use the host-native provider, set up GStack local browser, continue without browser evidence, or defer. A selection is not permission to install another product or attach private browser state.
+4. For a host-native selection, follow the matching provider section below. Never install an extension, grant site access, sign in, add an MCP server, attach an existing profile, or change host settings without the user's explicit action.
+5. After setup, run the common readiness journey. Tool names or metadata alone are insufficient evidence.
+6. If the journey fails, report \`needs-user-action\`, \`unavailable\`, or \`failed\` with the exact observed cause and offer the local GStack browser. Do not silently fall back.
+
+## Provider states
+
+- \`available\`: the current session exposes callable navigation, reading, and interaction tools, but readiness has not yet been proven.
+- \`needs-user-action\`: the host has a documented provider, but the user must enable, open, approve, or connect it.
+- \`ready\`: the selected provider passed the common local readiness journey in this session.
+- \`unavailable\`: no suitable interactive tool is exposed in the current session.
+- \`failed\`: a callable provider attempted the readiness journey and failed; include the exact failing step.
+
+Never report \`ready\` merely because a browser binary, CLI, plugin, extension, MCP name, settings entry, or documentation exists. Present one provider decision, then continue through the selected path. Do not run \`./setup\`; it is not a GStack 2 browser setup command.
+
+## Common local readiness journey
+
+Start the dependency-free fixture from this skill root with:
+
+\`node references/support/browser-provider-smoke.mjs\`
+
+The process prints one JSON line containing a loopback URL and remains alive. Through the selected browser provider:
+
+1. Open that exact URL.
+2. Verify the heading \`GStack browser readiness\`.
+3. Click \`Complete readiness check\`.
+4. Verify the page status becomes \`READY\`.
+5. When supported, confirm the console message \`gstack-browser-readiness:ready\` and the successful \`POST /proof\` request.
+6. Stop the fixture process and confirm it releases its listener.
+
+Mark the provider \`ready\` only after navigation, page reading, and interaction all succeed. The fixture binds to \`127.0.0.1\`, uses a per-run random token, sends no repository data, and does not persist cookies or credentials.
+
+${sections}
+
+## GStack local browser fallback
+
+GStack's existing local Chromium/Playwright implementation remains the only bundled browser backend. Follow \`RUNTIME.md\` for preview and separate install consent, run \`gstack doctor\`, then run the same readiness journey with the \`browse\` launcher. Do not run \`./setup\`, add a cloud browser, remote provider, alternate local backend, or personal-profile attachment as a fallback.

+# Browser provider setup and readiness
+
+Browser setup is optional and consented. The Agent Skills installer owns skill placement; this flow never enrolls another host. At onboarding, offer this flow only when the user asks to configure browser capabilities now. Otherwise run it just in time when a selected workflow first needs interactive browser evidence.
+
+## Routing flow
+
+1. Identify the active host and provider from callable tools in the current session, not from unrelated installed binaries, parent-application environment variables, documentation, or guessed host names. Inherited `CODEX_*`, bundle identifiers, and similar process metadata never override the actual agent/tool surface.
+2. Show the detected provider, what user-controlled setup it requires, and the GStack local-browser fallback.
+3. Ask whether to use the host-native provider, set up GStack local browser, continue without browser evidence, or defer. A selection is not permission to install another product or attach private browser state.
+4. For a host-native selection, follow the matching provider section below. Never install an extension, grant site access, sign in, add an MCP server, attach an existing profile, or change host settings without the user's explicit action.
+5. After setup, run the common readiness journey. Tool names or metadata alone are insufficient evidence.
+6. If the journey fails, report `needs-user-action`, `unavailable`, or `failed` with the exact observed cause and offer the local GStack browser. Do not silently fall back.
+
+## Provider states
+
+- `available`: the current session exposes callable navigation, reading, and interaction tools, but readiness has not yet been proven.
+- `needs-user-action`: the host has a documented provider, but the user must enable, open, approve, or connect it.
+- `ready`: the selected provider passed the common local readiness journey in this session.
+- `unavailable`: no suitable interactive tool is exposed in the current session.
+- `failed`: a callable provider attempted the readiness journey and failed; include the exact failing step.
+
+Never report `ready` merely because a browser binary, CLI, plugin, extension, MCP name, settings entry, or documentation exists. Present one provider decision, then continue through the selected path. Do not run `./setup`; it is not a GStack 2 browser setup command.
+
+## Common local readiness journey
+
+Start the dependency-free fixture from this skill root with:
+
+`node references/support/browser-provider-smoke.mjs`
+
+The process prints one JSON line containing a loopback URL and remains alive. Through the selected browser provider:
+
+1. Open that exact URL.
+2. Verify the heading `GStack browser readiness`.
+3. Click `Complete readiness check`.
+4. Verify the page status becomes `READY`.
+5. When supported, confirm the console message `gstack-browser-readiness:ready` and the successful `POST /proof` request.
+6. Stop the fixture process and confirm it releases its listener.
+
+Mark the provider `ready` only after navigation, page reading, and interaction all succeed. The fixture binds to `127.0.0.1`, uses a per-run random token, sends no repository data, and does not persist cookies or credentials.
+
+## Claude in Chrome
+
+Classification: `native-extension`
+
+Setup:
+
+1. Explain that Claude in Chrome requires Google Chrome, a paid Claude plan, the user-installed extension, the same signed-in Claude account, granted site permissions, and an enabled connector.
+2. Ask whether the user wants to configure it now. Never install the extension, grant permissions, enable a connector, sign in, or attach a Chrome profile for them.
+3. After the user completes setup, retry the active host tab/context discovery rather than treating the presence of the Claude CLI as browser readiness.
+
+Readiness evidence:
+
+- The Claude in Chrome tool surface is visible to the active Claude Code session.
+- Tab/context discovery returns an attached browser peer instead of a missing-extension or no-peer error.
+- The common local readiness journey completes through the Claude browser tools.
+
+If unavailable: Offer GStack local browser or continue without browser evidence; do not substitute a different extension or remote browser.
+
+## Codex built-in browser
+
+Classification: `native-in-app`
+
+Setup:
+
+1. Explain that the built-in browser is a ChatGPT desktop-app surface on macOS and Windows and uses its own browser state.
+2. Ask the user to open it from the Work/Codex toolbar (Command-Shift-B on macOS or Control-Shift-B on Windows) and approve the test site when prompted.
+3. Do not infer readiness from the Codex CLI or skill installation; the active session must expose an in-app browser provider.
+
+Readiness evidence:
+
+- Active browser discovery returns the in-app browser provider instead of an empty provider list.
+- A tab can be created or selected after the user opens the browser surface.
+- The common local readiness journey completes through the Codex browser tools.
+
+If unavailable: Offer GStack local browser or defer browser work; do not claim that restarting a browser-less session will create the missing host capability.
+
+## Gemini CLI browser agent
+
+Classification: `native-agent`
+
+Setup:
+
+1. Explain that Gemini CLI has an experimental bundled `browser_agent`, disabled by default, which requires a recent local Chrome and displays a first-run consent dialog.
+2. Ask whether the user wants to enable it themselves. Never edit Gemini settings, accept its consent dialog, attach an existing Chrome session, or infer readiness from the Gemini executable.
+3. Prefer Gemini isolated browser mode for public or localhost QA unless the user explicitly needs and approves an existing signed-in browser session.
+
+Readiness evidence:
+
+- The active Gemini session exposes the callable `browser_agent` tool rather than only `google_web_search` or `web_fetch`.
+- The user has completed Gemini's own enablement and one-time consent without GStack acting on their behalf.
+- The common local readiness journey completes through the Gemini browser agent.
+
+If unavailable: Offer the consented GStack local browser, evidence-limited fetch/search, or deferral; do not install a browser MCP because Gemini already bundles its experimental browser agent.
+
+## Cursor interactive browser provider
+
+Classification: `native-mcp`
+
+Setup:
+
+1. Inspect the active Cursor tool surface for an interactive provider such as Chrome DevTools; Cursor CLI presence and parent-process environment variables are not provider evidence.
+2. If an interactive provider is exposed, explain its current session/profile boundary and ask whether to use it. Never add or approve an MCP server, extension, or browser profile for the user.
+3. If no interactive provider is exposed in this Cursor session, offer GStack local browser rather than assuming every Cursor installation has the same browser tools.
+
+Readiness evidence:
+
+- The active Cursor session exposes callable navigation, page-reading, and interaction tools and returns a live browser peer.
+- The selected browser session does not require silently attaching the user's personal profile.
+- The common local readiness journey completes through the discovered Cursor provider.
+
+If unavailable: Offer GStack local browser, evidence-limited web access, or deferral; do not turn one machine's configured Chrome DevTools MCP into a universal Cursor capability claim.
+
+## GitHub Copilot and VS Code integrated browser
+
+Classification: `native-in-app`
+
+Setup:
+
+1. Explain that current VS Code can expose built-in browser agent tools, subject to the `workbench.browser.enableChatTools` organization setting and the user's active tool selection.
+2. Ask the user to enable the Built-in > Browser tools in the active agent session when they want to use them. Never change VS Code or organization settings for them.
+3. Prefer an agent-created isolated browser page; sharing an existing browser page or its signed-in state requires the user's explicit action.
+
+Readiness evidence:
+
+- The active Copilot/VS Code agent session exposes callable browser tools such as page navigation, reading, screenshot, and interaction.
+- An isolated browser page can be opened without silently sharing an existing tab or cookie store.
+- The common local readiness journey completes through the VS Code integrated browser tools.
+
+If unavailable: Offer GStack local browser or defer; distinguish organization-policy disablement from a transient missing browser tab.
+
+## OpenClaw browser plugin
+
+Classification: `native-plugin`
+
+Setup:
+
+1. Explain that OpenClaw includes a browser plugin with a dedicated managed profile, while its `user` profile can attach to an existing browser session.
+2. Inspect the active OpenClaw tool policy for the callable browser tool. Never edit `plugins.allow`, enable the plugin, or attach the `user` profile without explicit user action.
+3. Prefer the isolated managed profile for public and localhost QA; use an existing signed-in profile only when the user explicitly selects it.
+
+Readiness evidence:
+
+- The active OpenClaw agent exposes the browser tool after its plugin and tool-policy checks.
+- Browser doctor/status and tab discovery succeed for the explicitly selected profile.
+- The common local readiness journey completes through OpenClaw browser actions.
+
+If unavailable: Offer GStack local browser or defer; do not silently repair OpenClaw plugin policy or attach a personal browser profile.
+
+## Kimi Code
+
+Classification: `no-native-automation`
+
+Setup:
+
+1. Explain that Kimi Code loads standard Agent Skills and provides WebSearch/FetchURL when configured, but does not currently document a native interactive browser-automation harness.
+2. Do not describe `kimi web` as browser automation: it is the browser-based user interface for the Kimi session.
+3. Offer GStack local browser when interactive navigation, clicking, screenshots, console, or network evidence is required.
+
+Readiness evidence:
+
+- Kimi discovers the canonical GStack skills through its standard Agent Skills directories.
+- Fetch/search-only work may use Kimi host tools when their limitations satisfy the task.
+- Interactive browser readiness is tested against GStack local browser, not `kimi web`.
+
+If unavailable: Continue with fetch/search-only evidence or offer the consented GStack local browser; never silently add a browser MCP or alternate backend.
+
+## Pi coding agent
+
+Classification: `extension-only`
+
+Setup:
+
+1. Explain that Pi intentionally has no core interactive browser tool; browser automation is available only through optional third-party packages or an already exposed host tool.
+2. Inspect the active Pi tool surface. Never install a Pi package, run its browser installer, or treat a package listing as a live browser peer.
+3. Offer GStack local browser when no already-configured interactive provider is callable.
+
+Readiness evidence:
+
+- An explicitly user-installed Pi browser extension exposes a callable browser tool in the active session.
+- The extension returns a live isolated session without triggering an unapproved Chromium download or profile attachment.
+- The common local readiness journey completes through that active tool.
+
+If unavailable: Offer GStack local browser, evidence-limited continuation, or deferral; never recommend or install a third-party Pi browser package automatically.
+
+## GStack local browser fallback
+
+GStack's existing local Chromium/Playwright implementation remains the only bundled browser backend. Follow `RUNTIME.md` for preview and separate install consent, run `gstack doctor`, then run the same readiness journey with the `browse` launcher. Do not run `./setup`, add a cloud browser, remote provider, alternate local backend, or personal-profile attachment as a fallback.

 The six Agent Skills are useful without a GStack runtime. Never install, download, build, select, update, or remove runtime capabilities merely because a skill was invoked.
 
-When an active specialist first reaches a capability it cannot use, name the exact capability and why it is needed. Offer to continue without it when the judgment-only or host-native path remains valid. Installation requires the user's explicit approval after disclosing the selected capabilities, that an official versioned release artifact will be downloaded and SHA-256 verified, and any exact byte/build information available from the bootstrap manifest. Never call the bootstrap before approval.
+Before interactive browser work, read `references/BROWSER-PROVIDERS.md` in full. It owns provider detection, consented host setup, the common readiness journey, and the explicit GStack fallback. Skill installation never proves browser readiness.
 
-Capability names are `browser`, `design`, `pdf`, `diagram`, and `ios`; the core state/runtime CLI is managed separately. After approval, from this skill root run `node references/support/runtime-bootstrap.mjs install --capability <name>` (repeat `--capability` for additional approved capabilities). The dependency-free Node 18+ bootstrap accepts only official GStack GitHub Release hosts, validates the fixed manifest schema/version/skill API/platform artifact and SHA-256, verifies a declared Cosign bundle when Cosign is available, rejects unsafe archive paths/links, and invokes the atomic managed installer. Never run `./setup` inside a standard-installed skill directory, enroll a host, or treat skill installation as runtime consent.
+When an active specialist first reaches a capability it cannot use, name the exact capability and why it is needed. Offer to continue without it when the judgment-only or host-native path remains valid. Before any network preview, ask whether the user wants to check official setup options and exact sizes. Disclose that an uncached preview makes one public GitHub request for signed manifest metadata and sends no repository content, private URL, file, cookie, token, or credential; then STOP. A cached already-verified manifest may preview offline, but never silently fetch.
 
-Resolve capability dependencies before preview and approval: `diagram` implies `browser`; `pdf` implies both `diagram` and `browser` transitively. `design` and `ios` are standalone. The disclosure and approval must name the complete expanded set, not only the capability first requested.
+Only after the user approves that metadata check, run the non-mutating preview from this skill root: `node references/support/runtime-bootstrap.mjs preview --capability <name>` (repeat `--capability` for additional requested capabilities). It dependency-expands, reports already verified local components, exact missing components, and their summed compressed bytes. It never downloads components or mutates runtime state. Preview consent is not install consent.
 
-After doctor confirms readiness, canonical launcher bindings are `GSTACK_HOME=${GSTACK_HOME:-$HOME/.gstack}`, `GSTACK_BIN=$GSTACK_HOME/bin`, `B=$GSTACK_BIN/browse`, `D=$GSTACK_BIN/gstack-design`, and `P=$GSTACK_BIN/make-pdf`. Specialist modules may bind only the launchers they use. These assignments do not install or grant consent.
+User-facing setup capabilities are exactly `browser`, `design`, `diagram`, `pdf`, and `ios`. `all` means those five and intentionally excludes visible Chromium. The internal `browser-visible` capability is additive and is offered only when a workflow actually reaches a headed browser, extension, or browser-handoff step. Never offer it during ordinary headless QA.
+
+After showing the complete preview, STOP for explicit approval. Only after approval run `node references/support/runtime-bootstrap.mjs install --capability <name> --yes`; install must reprint the identical dependency-closed plan before downloading. Signed internal components are `core`, `browser-code` (browse code and dependencies), `browser-headless` (Playwright headless shell and FFmpeg), `browser-visible` (full Chromium), `design`, `diagram`, `pdf`, and `ios`. Logical `browser` expands to `browser-code + browser-headless`; internal `browser-visible` expands to `browser-code + browser-visible` and does not require headless. Component dependencies are `browser-code → core`, `browser-headless → browser-code`, and `browser-visible → browser-code`. `diagram` depends on logical `browser`; `pdf` depends on `diagram`; `ios` is Darwin-only. Therefore a first-time headed flow previews `core + browser-code + browser-visible`, while an existing verified headless runtime downloads only missing `browser-visible`. The manifest schema is v2 with global `capabilityComponents` and `componentDependencies`, plus `targets[target].components[id]` carrying signed exact-byte artifacts.
+
+The dependency-free Node 18+ bootstrap accepts only official GStack GitHub Release hosts, validates manifest/runtime/skill API/platform/component metadata and SHA-256, verifies a declared Cosign bundle when Cosign is available, rejects unsafe archive paths/links, and invokes the atomic managed installer. Never run `./setup` inside a standard-installed skill directory, enroll a host, or treat skill installation as runtime consent.
+
+After doctor confirms readiness, canonical launcher bindings are `GSTACK_HOME=${GSTACK_HOME:-$HOME/.gstack}`, `GSTACK_BIN=$GSTACK_HOME/bin`, `BUN_CMD=$GSTACK_BIN/bun`, `B=$GSTACK_BIN/browse`, `D=$GSTACK_BIN/gstack-design`, and `P=$GSTACK_BIN/make-pdf`. Specialist modules may bind only the launchers they use. These assignments do not install or grant consent. Never download or install a second Bun for GStack helpers; the managed runtime owns its pinned Bun executable in the active slot.
+
+Some retained helpers are shell scripts. `gstack doctor` verifies Bash and, on Windows, discovers Git for Windows Bash; disclose and stop at the affected helper if that prerequisite is unavailable. Python is not a global GStack prerequisite: only a specialist flow explicitly labeled as Python-dependent may request it, at the point of use and with the user's approval.
 
 The package/runtime compatibility tuple is `schemaVersion=1`, `runtimeVersion=2.0.0`, and `skillApi=2.0`; the machine-readable copy is `references/support/runtime-contract.json`. An incompatible active runtime is unavailable, not permission to upgrade it.
 
-The developer-only fallback is `node references/support/runtime-bootstrap.mjs install --source <reviewed-checkout> --capability <name>`; show its trust warning and use it only when the user explicitly selects a checkout they reviewed. If the packaged bootstrap is unavailable, stop capability setup instead of guessing a checkout-relative command. Deferring installation records no consent and must not block pure judgment.

+# Browser provider setup and readiness
+
+Browser setup is optional and consented. The Agent Skills installer owns skill placement; this flow never enrolls another host. At onboarding, offer this flow only when the user asks to configure browser capabilities now. Otherwise run it just in time when a selected workflow first needs interactive browser evidence.
+
+## Routing flow
+
+1. Identify the active host and provider from callable tools in the current session, not from unrelated installed binaries, parent-application environment variables, documentation, or guessed host names. Inherited `CODEX_*`, bundle identifiers, and similar process metadata never override the actual agent/tool surface.
+2. Show the detected provider, what user-controlled setup it requires, and the GStack local-browser fallback.
+3. Ask whether to use the host-native provider, set up GStack local browser, continue without browser evidence, or defer. A selection is not permission to install another product or attach private browser state.
+4. For a host-native selection, follow the matching provider section below. Never install an extension, grant site access, sign in, add an MCP server, attach an existing profile, or change host settings without the user's explicit action.
+5. After setup, run the common readiness journey. Tool names or metadata alone are insufficient evidence.
+6. If the journey fails, report `needs-user-action`, `unavailable`, or `failed` with the exact observed cause and offer the local GStack browser. Do not silently fall back.
+
+## Provider states
+
+- `available`: the current session exposes callable navigation, reading, and interaction tools, but readiness has not yet been proven.
+- `needs-user-action`: the host has a documented provider, but the user must enable, open, approve, or connect it.
+- `ready`: the selected provider passed the common local readiness journey in this session.
+- `unavailable`: no suitable interactive tool is exposed in the current session.
+- `failed`: a callable provider attempted the readiness journey and failed; include the exact failing step.
+
+Never report `ready` merely because a browser binary, CLI, plugin, extension, MCP name, settings entry, or documentation exists. Present one provider decision, then continue through the selected path. Do not run `./setup`; it is not a GStack 2 browser setup command.
+
+## Common local readiness journey
+
+Start the dependency-free fixture from this skill root with:
+
+`node references/support/browser-provider-smoke.mjs`
+
+The process prints one JSON line containing a loopback URL and remains alive. Through the selected browser provider:
+
+1. Open that exact URL.
+2. Verify the heading `GStack browser readiness`.
+3. Click `Complete readiness check`.
+4. Verify the page status becomes `READY`.
+5. When supported, confirm the console message `gstack-browser-readiness:ready` and the successful `POST /proof` request.
+6. Stop the fixture process and confirm it releases its listener.
+
+Mark the provider `ready` only after navigation, page reading, and interaction all succeed. The fixture binds to `127.0.0.1`, uses a per-run random token, sends no repository data, and does not persist cookies or credentials.
+
+## Claude in Chrome
+
+Classification: `native-extension`
+
+Setup:
+
+1. Explain that Claude in Chrome requires Google Chrome, a paid Claude plan, the user-installed extension, the same signed-in Claude account, granted site permissions, and an enabled connector.
+2. Ask whether the user wants to configure it now. Never install the extension, grant permissions, enable a connector, sign in, or attach a Chrome profile for them.
+3. After the user completes setup, retry the active host tab/context discovery rather than treating the presence of the Claude CLI as browser readiness.
+
+Readiness evidence:
+
+- The Claude in Chrome tool surface is visible to the active Claude Code session.
+- Tab/context discovery returns an attached browser peer instead of a missing-extension or no-peer error.
+- The common local readiness journey completes through the Claude browser tools.
+
+If unavailable: Offer GStack local browser or continue without browser evidence; do not substitute a different extension or remote browser.
+
+## Codex built-in browser
+
+Classification: `native-in-app`
+
+Setup:
+
+1. Explain that the built-in browser is a ChatGPT desktop-app surface on macOS and Windows and uses its own browser state.
+2. Ask the user to open it from the Work/Codex toolbar (Command-Shift-B on macOS or Control-Shift-B on Windows) and approve the test site when prompted.
+3. Do not infer readiness from the Codex CLI or skill installation; the active session must expose an in-app browser provider.
+
+Readiness evidence:
+
+- Active browser discovery returns the in-app browser provider instead of an empty provider list.
+- A tab can be created or selected after the user opens the browser surface.
+- The common local readiness journey completes through the Codex browser tools.
+
+If unavailable: Offer GStack local browser or defer browser work; do not claim that restarting a browser-less session will create the missing host capability.
+
+## Gemini CLI browser agent
+
+Classification: `native-agent`
+
+Setup:
+
+1. Explain that Gemini CLI has an experimental bundled `browser_agent`, disabled by default, which requires a recent local Chrome and displays a first-run consent dialog.
+2. Ask whether the user wants to enable it themselves. Never edit Gemini settings, accept its consent dialog, attach an existing Chrome session, or infer readiness from the Gemini executable.
+3. Prefer Gemini isolated browser mode for public or localhost QA unless the user explicitly needs and approves an existing signed-in browser session.
+
+Readiness evidence:
+
+- The active Gemini session exposes the callable `browser_agent` tool rather than only `google_web_search` or `web_fetch`.
+- The user has completed Gemini's own enablement and one-time consent without GStack acting on their behalf.
+- The common local readiness journey completes through the Gemini browser agent.
+
+If unavailable: Offer the consented GStack local browser, evidence-limited fetch/search, or deferral; do not install a browser MCP because Gemini already bundles its experimental browser agent.
+
+## Cursor interactive browser provider
+
+Classification: `native-mcp`
+
+Setup:
+
+1. Inspect the active Cursor tool surface for an interactive provider such as Chrome DevTools; Cursor CLI presence and parent-process environment variables are not provider evidence.
+2. If an interactive provider is exposed, explain its current session/profile boundary and ask whether to use it. Never add or approve an MCP server, extension, or browser profile for the user.
+3. If no interactive provider is exposed in this Cursor session, offer GStack local browser rather than assuming every Cursor installation has the same browser tools.
+
+Readiness evidence:
+
+- The active Cursor session exposes callable navigation, page-reading, and interaction tools and returns a live browser peer.
+- The selected browser session does not require silently attaching the user's personal profile.
+- The common local readiness journey completes through the discovered Cursor provider.
+
+If unavailable: Offer GStack local browser, evidence-limited web access, or deferral; do not turn one machine's configured Chrome DevTools MCP into a universal Cursor capability claim.
+
+## GitHub Copilot and VS Code integrated browser
+
+Classification: `native-in-app`
+
+Setup:
+
+1. Explain that current VS Code can expose built-in browser agent tools, subject to the `workbench.browser.enableChatTools` organization setting and the user's active tool selection.
+2. Ask the user to enable the Built-in > Browser tools in the active agent session when they want to use them. Never change VS Code or organization settings for them.
+3. Prefer an agent-created isolated browser page; sharing an existing browser page or its signed-in state requires the user's explicit action.
+
+Readiness evidence:
+
+- The active Copilot/VS Code agent session exposes callable browser tools such as page navigation, reading, screenshot, and interaction.
+- An isolated browser page can be opened without silently sharing an existing tab or cookie store.
+- The common local readiness journey completes through the VS Code integrated browser tools.
+
+If unavailable: Offer GStack local browser or defer; distinguish organization-policy disablement from a transient missing browser tab.
+
+## OpenClaw browser plugin
+
+Classification: `native-plugin`
+
+Setup:
+
+1. Explain that OpenClaw includes a browser plugin with a dedicated managed profile, while its `user` profile can attach to an existing browser session.
+2. Inspect the active OpenClaw tool policy for the callable browser tool. Never edit `plugins.allow`, enable the plugin, or attach the `user` profile without explicit user action.
+3. Prefer the isolated managed profile for public and localhost QA; use an existing signed-in profile only when the user explicitly selects it.
+
+Readiness evidence:
+
+- The active OpenClaw agent exposes the browser tool after its plugin and tool-policy checks.
+- Browser doctor/status and tab discovery succeed for the explicitly selected profile.
+- The common local readiness journey completes through OpenClaw browser actions.
+
+If unavailable: Offer GStack local browser or defer; do not silently repair OpenClaw plugin policy or attach a personal browser profile.
+
+## Kimi Code
+
+Classification: `no-native-automation`
+
+Setup:
+
+1. Explain that Kimi Code loads standard Agent Skills and provides WebSearch/FetchURL when configured, but does not currently document a native interactive browser-automation harness.
+2. Do not describe `kimi web` as browser automation: it is the browser-based user interface for the Kimi session.
+3. Offer GStack local browser when interactive navigation, clicking, screenshots, console, or network evidence is required.
+
+Readiness evidence:
+
+- Kimi discovers the canonical GStack skills through its standard Agent Skills directories.
+- Fetch/search-only work may use Kimi host tools when their limitations satisfy the task.
+- Interactive browser readiness is tested against GStack local browser, not `kimi web`.
+
+If unavailable: Continue with fetch/search-only evidence or offer the consented GStack local browser; never silently add a browser MCP or alternate backend.
+
+## Pi coding agent
+
+Classification: `extension-only`
+
+Setup:
+
+1. Explain that Pi intentionally has no core interactive browser tool; browser automation is available only through optional third-party packages or an already exposed host tool.
+2. Inspect the active Pi tool surface. Never install a Pi package, run its browser installer, or treat a package listing as a live browser peer.
+3. Offer GStack local browser when no already-configured interactive provider is callable.
+
+Readiness evidence:
+
+- An explicitly user-installed Pi browser extension exposes a callable browser tool in the active session.
+- The extension returns a live isolated session without triggering an unapproved Chromium download or profile attachment.
+- The common local readiness journey completes through that active tool.
+
+If unavailable: Offer GStack local browser, evidence-limited continuation, or deferral; never recommend or install a third-party Pi browser package automatically.
+
+## GStack local browser fallback
+
+GStack's existing local Chromium/Playwright implementation remains the only bundled browser backend. Follow `RUNTIME.md` for preview and separate install consent, run `gstack doctor`, then run the same readiness journey with the `browse` launcher. Do not run `./setup`, add a cloud browser, remote provider, alternate local backend, or personal-profile attachment as a fallback.

 The six Agent Skills are useful without a GStack runtime. Never install, download, build, select, update, or remove runtime capabilities merely because a skill was invoked.
 
-When an active specialist first reaches a capability it cannot use, name the exact capability and why it is needed. Offer to continue without it when the judgment-only or host-native path remains valid. Installation requires the user's explicit approval after disclosing the selected capabilities, that an official versioned release artifact will be downloaded and SHA-256 verified, and any exact byte/build information available from the bootstrap manifest. Never call the bootstrap before approval.
+Before interactive browser work, read `references/BROWSER-PROVIDERS.md` in full. It owns provider detection, consented host setup, the common readiness journey, and the explicit GStack fallback. Skill installation never proves browser readiness.
 
-Capability names are `browser`, `design`, `pdf`, `diagram`, and `ios`; the core state/runtime CLI is managed separately. After approval, from this skill root run `node references/support/runtime-bootstrap.mjs install --capability <name>` (repeat `--capability` for additional approved capabilities). The dependency-free Node 18+ bootstrap accepts only official GStack GitHub Release hosts, validates the fixed manifest schema/version/skill API/platform artifact and SHA-256, verifies a declared Cosign bundle when Cosign is available, rejects unsafe archive paths/links, and invokes the atomic managed installer. Never run `./setup` inside a standard-installed skill directory, enroll a host, or treat skill installation as runtime consent.
+When an active specialist first reaches a capability it cannot use, name the exact capability and why it is needed. Offer to continue without it when the judgment-only or host-native path remains valid. Before any network preview, ask whether the user wants to check official setup options and exact sizes. Disclose that an uncached preview makes one public GitHub request for signed manifest metadata and sends no repository content, private URL, file, cookie, token, or credential; then STOP. A cached already-verified manifest may preview offline, but never silently fetch.
 
-Resolve capability dependencies before preview and approval: `diagram` implies `browser`; `pdf` implies both `diagram` and `browser` transitively. `design` and `ios` are standalone. The disclosure and approval must name the complete expanded set, not only the capability first requested.
+Only after the user approves that metadata check, run the non-mutating preview from this skill root: `node references/support/runtime-bootstrap.mjs preview --capability <name>` (repeat `--capability` for additional requested capabilities). It dependency-expands, reports already verified local components, exact missing components, and their summed compressed bytes. It never downloads components or mutates runtime state. Preview consent is not install consent.
 
-After doctor confirms readiness, canonical launcher bindings are `GSTACK_HOME=${GSTACK_HOME:-$HOME/.gstack}`, `GSTACK_BIN=$GSTACK_HOME/bin`, `B=$GSTACK_BIN/browse`, `D=$GSTACK_BIN/gstack-design`, and `P=$GSTACK_BIN/make-pdf`. Specialist modules may bind only the launchers they use. These assignments do not install or grant consent.
+User-facing setup capabilities are exactly `browser`, `design`, `diagram`, `pdf`, and `ios`. `all` means those five and intentionally excludes visible Chromium. The internal `browser-visible` capability is additive and is offered only when a workflow actually reaches a headed browser, extension, or browser-handoff step. Never offer it during ordinary headless QA.
+
+After showing the complete preview, STOP for explicit approval. Only after approval run `node references/support/runtime-bootstrap.mjs install --capability <name> --yes`; install must reprint the identical dependency-closed plan before downloading. Signed internal components are `core`, `browser-code` (browse code and dependencies), `browser-headless` (Playwright headless shell and FFmpeg), `browser-visible` (full Chromium), `design`, `diagram`, `pdf`, and `ios`. Logical `browser` expands to `browser-code + browser-headless`; internal `browser-visible` expands to `browser-code + browser-visible` and does not require headless. Component dependencies are `browser-code → core`, `browser-headless → browser-code`, and `browser-visible → browser-code`. `diagram` depends on logical `browser`; `pdf` depends on `diagram`; `ios` is Darwin-only. Therefore a first-time headed flow previews `core + browser-code + browser-visible`, while an existing verified headless runtime downloads only missing `browser-visible`. The manifest schema is v2 with global `capabilityComponents` and `componentDependencies`, plus `targets[target].components[id]` carrying signed exact-byte artifacts.
+
+The dependency-free Node 18+ bootstrap accepts only official GStack GitHub Release hosts, validates manifest/runtime/skill API/platform/component metadata and SHA-256, verifies a declared Cosign bundle when Cosign is available, rejects unsafe archive paths/links, and invokes the atomic managed installer. Never run `./setup` inside a standard-installed skill directory, enroll a host, or treat skill installation as runtime consent.
+
+After doctor confirms readiness, canonical launcher bindings are `GSTACK_HOME=${GSTACK_HOME:-$HOME/.gstack}`, `GSTACK_BIN=$GSTACK_HOME/bin`, `BUN_CMD=$GSTACK_BIN/bun`, `B=$GSTACK_BIN/browse`, `D=$GSTACK_BIN/gstack-design`, and `P=$GSTACK_BIN/make-pdf`. Specialist modules may bind only the launchers they use. These assignments do not install or grant consent. Never download or install a second Bun for GStack helpers; the managed runtime owns its pinned Bun executable in the active slot.
+
+Some retained helpers are shell scripts. `gstack doctor` verifies Bash and, on Windows, discovers Git for Windows Bash; disclose and stop at the affected helper if that prerequisite is unavailable. Python is not a global GStack prerequisite: only a specialist flow explicitly labeled as Python-dependent may request it, at the point of use and with the user's approval.
 
 The package/runtime compatibility tuple is `schemaVersion=1`, `runtimeVersion=2.0.0`, and `skillApi=2.0`; the machine-readable copy is `references/support/runtime-contract.json`. An incompatible active runtime is unavailable, not permission to upgrade it.
 
-The developer-only fallback is `node references/support/runtime-bootstrap.mjs install --source <reviewed-checkout> --capability <name>`; show its trust warning and use it only when the user explicitly selects a checkout they reviewed. If the packaged bootstrap is unavailable, stop capability setup instead of guessing a checkout-relative command. Deferring installation records no consent and must not block pure judgment.

 If browse is not available, that's fine — visual research is optional. The skill works without it using WebSearch and your built-in design knowledge.
