 # Changelog
 
+## [0.13.9.0] - 2026-03-29 — Composable Skills
+
+Skills can now load other skills inline. Write `{{INVOKE_SKILL:office-hours}}` in a template and the generator emits the right "read file, skip preamble, follow instructions" prose automatically. Handles host-aware paths and customizable skip lists.
+
+### Added
+
+- **`{{INVOKE_SKILL:skill-name}}` resolver.** Composable skill loading as a first-class resolver. Emits host-aware prose that tells Claude or Codex to read another skill's SKILL.md and follow it inline, skipping preamble sections. Supports optional `skip=` parameter for additional sections to skip.
+- **Parameterized resolver support.** The placeholder regex now handles `{{NAME:arg1:arg2}}`, enabling resolvers that take arguments at generation time. Fully backward compatible with existing `{{NAME}}` patterns.
+- **`{{CHANGELOG_WORKFLOW}}` resolver.** Changelog generation logic extracted from /ship into a reusable resolver. Includes voice guidance ("lead with what the user can now do") inline.
+- **Frontmatter `name:` for skill registration.** Setup script and gen-skill-docs now read `name:` from SKILL.md frontmatter for symlink naming. Enables directory names that differ from invocation names (e.g., `run-tests/` directory registered as `/test`).
+- **Proactive skill routing.** Skills now ask once to add routing rules to your project's CLAUDE.md. This makes Claude invoke the right skill automatically instead of answering directly. Your choice is remembered in `~/.gstack/config.yaml`.
+- **Annotated config file.** `~/.gstack/config.yaml` now gets a documented header on first creation explaining every setting. Edit it anytime.
+
+### Changed
+
+- **BENEFITS_FROM now delegates to INVOKE_SKILL.** Eliminated duplicated skip-list logic. The prerequisite offer wrapper stays in BENEFITS_FROM, but the actual "read and follow" instructions come from INVOKE_SKILL.
+- **/plan-ceo-review mid-session fallback uses INVOKE_SKILL.** The "user can't articulate the problem, offer /office-hours" path now uses the composable resolver instead of inline prose.
+- **Stronger routing language.** office-hours, investigate, and ship descriptions now say "Proactively invoke" instead of "Proactively suggest" for more reliable automatic skill invocation.
+
+### Fixed
+
+- **Config grep anchored to line start.** Commented header lines no longer shadow real config values.
+
+## [0.13.8.0] - 2026-03-29 — Security Audit Round 2
+
+Browse output is now wrapped in trust boundary markers so agents can tell page content from tool output. Markers are escape-proof. The Chrome extension validates message senders. CDP binds to localhost only. Bun installs use checksum verification.
+
+### Fixed
+
+- **Trust boundary markers are escape-proof.** URLs sanitized (no newlines), marker strings escaped in content. A malicious page can't forge the END marker to break out of the untrusted block.
+
+### Added
+
+- **Content trust boundary markers.** Every browse command that returns page content (`text`, `html`, `links`, `forms`, `accessibility`, `console`, `dialog`, `snapshot`, `diff`, `resume`, `watch stop`) wraps output in `--- BEGIN/END UNTRUSTED EXTERNAL CONTENT ---` markers. Agents know what's page content vs tool output.
+- **Extension sender validation.** Chrome extension rejects messages from unknown senders and enforces a message type allowlist. Prevents cross-extension message spoofing.
+- **CDP localhost-only binding.** `bin/chrome-cdp` now passes `--remote-debugging-address=127.0.0.1` and `--remote-allow-origins` to prevent remote debugging exposure.
+- **Checksum-verified bun install.** The browse SKILL.md bootstrap now downloads the bun install script to a temp file and verifies SHA-256 before executing. No more piping curl to bash.
+
+### Removed
+
+- **Factory Droid support.** Removed `--host factory`, `.factory/` generated skills, Factory CI checks, and all Factory-specific code paths.
+
+## [0.13.7.0] - 2026-03-29 — Community Wave
+
+Six community fixes with 16 new tests. Telemetry off now means off everywhere. Skills are findable by name. And changing your prefix setting actually works now.
+
+### Fixed
+
+- **Telemetry off means off everywhere.** When you set telemetry to off, gstack no longer writes local JSONL analytics files. Previously "off" only stopped remote reporting. Now nothing is written anywhere. Clean trust contract.
+- **`find -delete` replaced with POSIX `-exec rm`.** Safety Net and other non-GNU environments no longer choke on session cleanup.
+- **No more preemptive context warnings.** `/plan-eng-review` no longer warns you about running low on context. The system handles compaction automatically.
+- **Sidebar security test updated** for Write tool fallback string change.
+- **`gstack-relink` no longer double-prefixes `gstack-upgrade`.** Setting `skill_prefix=true` was creating `gstack-gstack-upgrade` instead of keeping the existing name. Now matches `setup` script behavior.
+
+### Added
+
+- **Skill discoverability.** Every skill description now contains "(gstack)" so you can find gstack skills by searching in Claude Code's command palette.
+- **Feature signal detection in `/ship`.** Version bump now checks for new routes, migrations, test+source pairs, and `feat/` branches. Catches MINOR-worthy changes that line count alone misses.
+- **Sidebar Write tool.** Both the sidebar agent and headed-mode server now include Write in allowedTools. Write doesn't expand the attack surface beyond what Bash already provides.
+- **Sidebar stderr capture.** The sidebar agent now buffers stderr and includes it in error and timeout messages instead of silently discarding it.
+- **`bin/gstack-relink`** re-creates skill symlinks when you change `skill_prefix` via `gstack-config set`. No more manual `./setup` re-run needed.
+- **`bin/gstack-open-url`** cross-platform URL opener (macOS: `open`, Linux: `xdg-open`, Windows: `start`).
+
 ## [0.13.6.0] - 2026-03-29 — GStack Learns
 
 Every session now makes the next one smarter. gstack remembers patterns, pitfalls, and preferences across sessions and uses them to improve every review, plan, debug, and ship. The more you use it, the better it gets on your codebase.

+## Skill routing
+
+When the user's request matches an available skill, ALWAYS invoke it using the Skill
+tool as your FIRST action. Do NOT answer directly, do NOT use other tools first.
+The skill has specialized workflows that produce better results than ad-hoc answers.
+
+Key routing rules:
+- Product ideas, "is this worth building", brainstorming → invoke office-hours
+- Bugs, errors, "why is this broken", 500 errors → invoke investigate
+- Ship, deploy, push, create PR → invoke ship
+- QA, test the site, find bugs → invoke qa
+- Code review, check my diff → invoke review
+- Update docs after shipping → invoke document-release
+- Weekly retro → invoke retro
+- Design system, brand → invoke design-consultation
+- Visual audit, design polish → invoke design-review
+- Architecture review → invoke plan-eng-review

+> This tells Claude to use specialized workflows (like /ship, /investigate, /qa)

+
+Options:
+- A) Add routing rules to CLAUDE.md (recommended)
+- B) No thanks, I'll invoke skills manually
+
+If A: Append this section to the end of CLAUDE.md:
+
+```markdown
+
+## Skill routing
+
+When the user's request matches an available skill, ALWAYS invoke it using the Skill
+tool as your FIRST action. Do NOT answer directly, do NOT use other tools first.
+The skill has specialized workflows that produce better results than ad-hoc answers.
+
+Key routing rules:
+- Product ideas, "is this worth building", brainstorming → invoke office-hours
+- Bugs, errors, "why is this broken", 500 errors → invoke investigate
+- Ship, deploy, push, create PR → invoke ship
+- QA, test the site, find bugs → invoke qa
+- Code review, check my diff → invoke review
+- Update docs after shipping → invoke document-release
+- Weekly retro → invoke retro
+- Design system, brand → invoke design-consultation
+- Visual audit, design polish → invoke design-review
+- Architecture review → invoke plan-eng-review
+```
+
+Then commit the change: `git add CLAUDE.md && git commit -m "chore: add gstack skill routing rules to CLAUDE.md"`
+
+If B: run `~/.claude/skills/gstack/bin/gstack-config set routing_declined true`
+Say "No problem. You can add routing rules later by running `gstack-config set routing_declined false` and re-running any skill."
+
+This only happens once per project. If `HAS_ROUTING` is `yes` or `ROUTING_DECLINED` is `true`, skip this entirely.

-## Step 5: CHANGELOG (auto-generate)
-
-1. Read `CHANGELOG.md` header to know the format.
-
-2. **First, enumerate every commit on the branch:**
-   ```bash
-   git log <base>..HEAD --oneline
-   ```
-   Copy the full list. Count the commits. You will use this as a checklist.
-
-3. **Read the full diff** to understand what each commit actually changed:
-   ```bash
-   git diff <base>...HEAD
-   ```
-
-4. **Group commits by theme** before writing anything. Common themes:
-   - New features / capabilities
-   - Performance improvements
-   - Bug fixes
-   - Dead code removal / cleanup
-   - Infrastructure / tooling / tests
-   - Refactoring
-
-5. **Write the CHANGELOG entry** covering ALL groups:
-   - If existing CHANGELOG entries on the branch already cover some commits, replace them with one unified entry for the new version
-   - Categorize changes into applicable sections:
-     - `### Added` — new features
-     - `### Changed` — changes to existing functionality
-     - `### Fixed` — bug fixes
-     - `### Removed` — removed features
-   - Write concise, descriptive bullet points
-   - Insert after the file header (line 5), dated today
-   - Format: `## [X.Y.Z.W] - YYYY-MM-DD`
-
-6. **Cross-check:** Compare your CHANGELOG entry against the commit list from step 2.
-   Every commit must map to at least one bullet point. If any commit is unrepresented,
-   add it now. If the branch has N commits spanning K themes, the CHANGELOG must
-   reflect all K themes.
-
-**Do NOT ask the user to describe changes.** Infer from the diff and commit history.

+- Code review, check my diff → invoke review
