Garry Tan b805aa0113 feat: Confusion Protocol, Hermes + GBrain hosts, brain-first resolver (v0.18.0.0) (#1005)
* feat: add Confusion Protocol to preamble resolver

Injects a high-stakes ambiguity gate at preamble tier >= 2 so all
workflow skills get it. Fires when Claude encounters architectural
decisions, data model changes, destructive operations, or contradictory
requirements. Does NOT fire on routine coding.

Addresses Karpathy failure mode #1 (wrong assumptions) with an
inline STOP gate instead of relying on workflow skill invocation.

* feat: add Hermes and GBrain host configs

Hermes: tool rewrites for terminal/read_file/patch/delegate_task,
paths to ~/.hermes/skills/gstack, AGENTS.md config file.

GBrain: coding skills become brain-aware when GBrain mod is installed.
Same tool rewrites as OpenClaw (agents spawn Claude Code via ACP).
GBRAIN_CONTEXT_LOAD and GBRAIN_SAVE_RESULTS NOT suppressed on gbrain
host, enabling brain-first lookup and save-to-brain behavior.

Both registered in hosts/index.ts with setup script redirect messages.

* feat: GBrain resolver — brain-first lookup and save-to-brain

New scripts/resolvers/gbrain.ts with two resolver functions:
- GBRAIN_CONTEXT_LOAD: search brain for context before skill starts
- GBRAIN_SAVE_RESULTS: save skill output to brain after completion

Placeholders added to 4 thinking skill templates (office-hours,
investigate, plan-ceo-review, retro). Resolves to empty string on
all hosts except gbrain via suppressedResolvers.

GBRAIN suppression added to all 9 non-gbrain host configs.

* feat: wire slop:diff into /review as advisory diagnostic

Adds Step 3.5 to the review template: runs bun run slop:diff against
the base branch to catch AI code quality issues (empty catches,
redundant return await, overcomplicated abstractions). Advisory only,
never blocking. Skips silently if slop-scan is not installed.

* docs: add Karpathy compatibility note to README

Positions gstack as the workflow enforcement layer for Karpathy-style
CLAUDE.md rules (17K stars). Links to forrestchang/andrej-karpathy-skills.
Maps each Karpathy failure mode to the gstack skill that addresses it.

* fix: improve native OpenClaw thinking skills

office-hours: add design doc path visibility message after writing
ceo-review: add HARD GATE reminder at review section transitions
retro: add non-git context support (check memory for meeting notes)

Mirrors template improvements to hand-crafted native skills.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: update tests and golden fixtures for new hosts

- Host count: 8 → 10 (hermes, gbrain)
- OpenClaw adapter test: expects undefined (dead code removed)
- Golden ship fixtures: updated with Confusion Protocol + vendoring

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: regenerate all SKILL.md files

Regenerated from templates after Confusion Protocol, GBrain resolver
placeholders, slop:diff in review, HARD GATE reminders, investigation
learnings, design doc visibility, and retro non-git context changes.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update project documentation for v0.18.0.0

- CHANGELOG: add v0.18.0.0 entry (Confusion Protocol, Hermes, GBrain,
  slop in review, Karpathy note, skill improvements)
- CLAUDE.md: add hermes.ts and gbrain.ts to hosts listing
- README.md: update agent count 8→10, add Hermes + GBrain to table
- VERSION: bump to 0.18.0.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: sync package.json version to 0.18.0.0

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: extract Step 0 from review SKILL.md in E2E test

The review-base-branch E2E test was copying the full 1493-line
review/SKILL.md into the test fixture. The agent spent 8+ turns
reading it in chunks, leaving only 7 turns for actual work, causing
error_max_turns on every attempt.

Now extracts only Step 0 (base branch detection, ~50 lines) which is
all the test actually needs. Follows the CLAUDE.md rule: "NEVER copy
a full SKILL.md file into an E2E test fixture."

* feat: update GBrain and Hermes host configs for v0.10.0 integration

GBrain: add 'triggers' to keepFields so generated skills pass
checkResolvable() validation. Add version compat comment.

Hermes: un-suppress GBRAIN_CONTEXT_LOAD and GBRAIN_SAVE_RESULTS.
The resolvers handle GBrain-not-installed gracefully, so Hermes
agents with GBrain as a mod get brain features automatically.

* feat: GBrain resolver DX improvements and preamble health check

Resolver changes:
- gbrain query → gbrain search (fast keyword search, not expensive hybrid)
- Add keyword extraction guidance for agents
- Show explicit gbrain put_page syntax with --title, --tags, heredoc
- Add entity enrichment with false-positive filter
- Name throttle error patterns (exit code 1, stderr keywords)
- Add data-research routing for investigate skill
- Expand skillSaveMap from 4 to 8 entries
- Add brain operation telemetry summary

Preamble changes:
- Add gbrain doctor --fast --json health check for gbrain/hermes hosts
- Parse check failures/warnings count
- Show failing check details when score < 50

* fix: preserve keepFields in allowlist frontmatter mode

The allowlist mode hard-coded name + description reconstruction but
never iterated keepFields for additional fields. Adding 'triggers'
to keepFields was a no-op because the field was silently stripped.

Now iterates keepFields and preserves any field beyond name/description
from the source template frontmatter, including YAML arrays.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add triggers to all 38 skill templates

Multi-word, skill-specific trigger keywords for GBrain's RESOLVER.md
router. Each skill gets 3-6 triggers derived from its "Use when asked
to..." description text. Avoids single generic words that would collide
across skills (e.g., "debug this" not "debug").

These are distinct from voice-triggers (speech-to-text aliases) and
serve GBrain's checkResolvable() validation.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: regenerate all SKILL.md files and update golden fixtures

Regenerated from updated templates (triggers, brain placeholders,
resolver DX improvements, preamble health check). Golden fixtures
updated to match.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: settings-hook remove exits 1 when nothing to remove

gstack-settings-hook remove was exiting 0 when settings.json didn't
exist, causing gstack-uninstall to report "SessionStart hook" as
removed on clean systems where nothing was installed.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: update project documentation for GBrain v0.10.0 integration

ARCHITECTURE.md: added GBRAIN_CONTEXT_LOAD and GBRAIN_SAVE_RESULTS
to resolver table.

CHANGELOG.md: expanded v0.18.0.0 entry with GBrain v0.10.0 integration
details (triggers, expanded brain-awareness, DX improvements, Hermes
brain support), updated date.

CLAUDE.md: added gbrain to resolvers/ directory comment.

* fix: routing E2E stops writing to user's ~/.claude/skills/

installSkills() was copying SKILL.md files to both project-level
(.claude/skills/ in tmpDir) and user-level (~/.claude/skills/).
Writing to the user's real install fails when symlinks point to
different worktrees or dangling targets (ENOENT on copyFileSync).

Now installs to project-level only. The test already sets cwd to
the tmpDir, so project-level discovery works.

* chore: scale Gemini E2E back to smoke test

Gemini CLI gets lost in worktrees on complex tasks (review times out
at 600s, discover-skill hits exit 124). Nobody uses Gemini for gstack
skill execution. Replace the two failing tests (gemini-discover-skill
and gemini-review-findings) with a single smoke test that verifies
Gemini can start and read the README. 90s timeout, no skill invocation.

Garry Tan 7e96fe299b fix: security wave 3 — 12 fixes, 7 contributors (v0.16.4.0) (#988)
* fix(security): validateOutputPath symlink bypass — check file-level symlinks

validateOutputPath() previously only resolved symlinks on the parent directory.
A symlink at /tmp/evil.png → /etc/crontab passed the parent check (parent is
/tmp, which is safe) but the write followed the symlink outside safe dirs.

Add lstatSync() check: if the target file exists and is a symlink, resolve
through it and verify the real target is within SAFE_DIRECTORIES. ENOENT
(file doesn't exist yet) falls through to the existing parent-dir check.

Closes #921

* fix(security): shell injection in bin/ scripts — use env vars instead of interpolation

gstack-settings-hook interpolated $SETTINGS_FILE directly into bun -e
double-quoted blocks. A path containing quotes or backticks breaks the JS
string context, enabling arbitrary code execution.

Replace direct interpolation with environment variables (process.env).
Same fix applied to gstack-team-init which had the same pattern.

Systematic audit confirmed only these two scripts were vulnerable — all
other bin/ scripts already use stdin piping or env vars.

Closes #858

* fix(security): cookie-import path validation bypass + hardcoded /tmp

Two fixes:
1. cookie-import relative path bypass (#707): path.isAbsolute() gated the
   entire validation, so relative paths like "sensitive-file.json" bypassed
   the safe-directory check entirely. Now always resolves to absolute path
   with realpathSync for symlink resolution, matching validateOutputPath().

2. Hardcoded /tmp in cookie-import-browser (#708): openDbFromCopy used
   /tmp directly instead of os.tmpdir(), breaking Windows support.

Also adds explicit imports for SAFE_DIRECTORIES and isPathWithin in
write-commands.ts (previously resolved implicitly through bundler).

Closes #852

* fix(security): redact form fields with sensitive names, not just type=password

Form redaction only applied to type="password" fields. Hidden and text
fields named csrf_token, api_key, session_id, etc. were exposed unredacted
in LLM context, leaking secrets.

Extend redaction to check field name and id against sensitive patterns:
token, secret, key, password, credential, auth, jwt, session, csrf, sid,
api_key. Uses the same pattern style as SENSITIVE_COOKIE_NAME.

Closes #860

* fix(security): restrict session file permissions to owner-only

Design session files written to /tmp with default umask (0644) were
world-readable on shared systems. Sessions contain design prompts and
feedback history.

Set mode 0o600 (owner read/write only) on both create and update paths.

Closes #859

Co-Authored-By: Gus <garagon@users.noreply.github.com>

* fix(security): enforce frozen lockfile during setup

bun install without --frozen-lockfile resolves ^semver ranges from npm on
every run. If an attacker publishes a compromised compatible version of any
dependency, the next ./setup pulls it silently.

Add --frozen-lockfile with fallback to plain install (for fresh clones
where bun.lock may not exist yet). Matches the pattern already used in
the .agents/ generation block (line 237).

Closes #614

* fix: remove duplicate recursive chmod on /tmp in Dockerfile.ci

chmod -R 1777 /tmp recursively sets sticky bit on files (no defined
behavior), not just the directory. Deduplicate to single chmod 1777 /tmp.

Closes #747

* fix(security): learnings input validation + cross-project trust gate

Three fixes to the learnings system:

1. Input validation in gstack-learnings-log: type must be from allowed list,
   key must be alphanumeric, confidence must be 1-10 integer, source must
   be from allowed list. Prevents injection via malformed fields.

2. Prompt injection defense: insight field checked against 10 instruction-like
   patterns (ignore previous, system:, override, etc.). Rejected with clear
   error message.

3. Cross-project trust gate in gstack-learnings-search: AI-generated learnings
   from other projects are filtered out. Only user-stated learnings cross
   project boundaries. Prevents silent prompt injection across codebases.

Also adds trusted field (true for user-stated source, false for AI-generated)
to enable the trust gate at read time.

* feat(security): track cookie-imported domains and scope cookie imports

Foundation for origin-pinned JS execution (#616). Tracks which domains
cookies were imported from so the JS/eval commands can verify execution
stays within imported origins.

Changes:
- BrowserManager: new cookieImportedDomains Set with track/get/has methods
- cookie-import: tracks imported cookie domains after addCookies
- cookie-import-browser: tracks domains on --domain direct import
- cookie-import-browser --all: new explicit opt-in for all-domain import
  (previously implicit behavior, now requires deliberate flag)

Closes #615

Co-Authored-By: Alberto Martinez <halbert04@users.noreply.github.com>

* feat(security): pin JS/eval execution to cookie-imported origins

When cookies have been imported for specific domains, block JS execution
on pages whose origin doesn't match. Prevents the attack chain:
1. Agent imports cookies for github.com
2. Prompt injection navigates to attacker.com
3. Agent runs js document.cookie → exfiltrates github cookies

assertJsOriginAllowed() checks the current page hostname against imported
cookie domains with subdomain matching (.github.com allows api.github.com).
When no cookies are imported, all origins allowed (nothing to protect).
about:blank and data: URIs are allowed (no cookies at risk).

Depends on #615 (cookie domain tracking).

Closes #616

* feat(security): add persistent command audit log

Append-only JSONL audit trail for all browse server commands. Unlike
in-memory ring buffers, the audit log persists across restarts and is
never truncated. Each entry records: timestamp, command, args (truncated
to 200 chars), page origin, duration, status, error (truncated to 300
chars), hasCookies flag, connection mode.

All writes are best-effort — audit failures never block command execution.
Log stored at ~/.gstack/.browse/browse-audit.jsonl.

Closes #617

* fix(security): block hex-encoded IPv4-mapped IPv6 metadata bypass

URL constructor normalizes ::ffff:169.254.169.254 to ::ffff:a9fe:a9fe
(hex form), which was not in the blocklist. Similarly, ::169.254.169.254
normalizes to ::a9fe:a9fe.

Add both hex-encoded forms to BLOCKED_METADATA_HOSTS so they're caught
by the direct hostname check in validateNavigationUrl.

Closes #739

Co-Authored-By: Osman Mehmood <mehmoodosman@users.noreply.github.com>

* chore: bump version and changelog (v0.16.4.0)

Security wave 3: 12 fixes, 7 contributors.
Cookie origin pinning, command audit log, domain tracking.
Symlink bypass, path validation, shell injection, form redaction,
learnings injection, IPv6 SSRF, session permissions, frozen lockfile.

Garry Tan dae251e066 feat: team-friendly gstack install mode (v0.15.7.0) (#809)
* feat: add gstack-settings-hook for atomic Claude Code hook management

DRY helper for adding/removing SessionStart hooks in ~/.claude/settings.json.
Handles missing files, deduplication, malformed JSON, and atomic writes
(.tmp + rename) to prevent corruption on crash or disk-full.

Part of team-install-mode feature (credit: Jared Friedman).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add gstack-session-update for automatic team updates

SessionStart hook target that auto-updates gstack at session start.
Background fork (zero latency), throttled to once/hour, with lockfile
(mkdir + PID), stale lock recovery, GIT_TERMINAL_PROMPT=0, and debug
logging to ~/.gstack/analytics/session-update.log.

Part of team-install-mode feature (credit: Jared Friedman).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add --team, --no-team, -q flags to setup

--team enables auto_upgrade and registers SessionStart hook via
gstack-settings-hook. --no-team reverses it. -q/--quiet suppresses
all informational output (for hook-triggered setup runs). --local
now prints a deprecation warning.

Replaces ~20 echo calls with log() helper for quiet mode support.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add gstack-team-init for repo-level team bootstrapping

Two modes: 'optional' (gentle CLAUDE.md suggestion) and 'required'
(CLAUDE.md enforcement + .claude/hooks/check-gstack.sh PreToolUse hook
that blocks work without gstack installed). Atomic JSON writes,
idempotent, prints git add instructions.

Part of team-install-mode feature (credit: Jared Friedman).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: deprecate vendoring, document team mode, clean up uninstall

- README: replace "Step 2: Add to your repo" vendoring instructions
  with team mode (./setup --team + gstack-team-init)
- CLAUDE.md: rename "Vendored symlink awareness" to "Dev symlink
  awareness", add deprecation note
- CONTRIBUTING.md: remove vendoring language from prefix section
- bin/gstack-uninstall: clean up SessionStart hook on uninstall

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add vendoring deprecation detection to skill preamble

Detects vendored gstack in CWD (.claude/skills/gstack/ that's not a
symlink and has VERSION or .git). Outputs VENDORED_GSTACK: yes/no.
Adds generateVendoringDeprecation() section that offers one-time
migration to team mode via AskUserQuestion.

* feat: team mode (v0.15.7.0) — credit Jared Friedman

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add integration tests for team mode (20 tests)

Covers gstack-settings-hook (add, remove, dedup, preserve existing,
atomic write), gstack-session-update (guards, throttle, non-fatal),
gstack-team-init (optional, required, enforcement hook, idempotent),
and setup flags (-q, --local deprecation).
