merge: origin/main into garrytan/injection-tuning; bump v1.5.2.0 → v1.6.2.0
Main shipped v1.6.0.0 (security tunnel dual-listener + SSRF + envelope wave) and v1.6.1.0 (Opus 4.7 migration) while this branch was developing injection-tuning. Merging to keep the branch in sync. CHANGELOG: reverse-chronological order preserved — v1.6.1.0 > v1.6.0.0 > v1.5.2.0 (our branch entry) > v1.5.1.0 > ... VERSION: bumped to 1.6.2.0 per CLAUDE.md "branch always ahead of main after merge" discipline. package.json: synced to 1.6.2.0. Auto-merged: 58+ files (skill docs regenerated from .tmpl changes, routing injection, preamble resolvers). No real conflicts in security-related source files. Security test suite: 231 pass, 1 skip, 0 fail post-merge. Detection/FP numbers unchanged (56.2% / 22.9%).

## 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.
|
||||
When the user's request matches an available skill, invoke it via the Skill tool. The
|
||||
skill has multi-step workflows, checklists, and quality gates that produce better
|
||||
results than an ad-hoc answer. When in doubt, invoke the skill. A false positive is
|
||||
cheaper than a false negative.
|
||||
|
||||
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
|
||||
- Save progress, checkpoint, resume → invoke checkpoint
|
||||
- Code quality, health check → invoke health
|
||||
- Product ideas, "is this worth building", brainstorming → invoke /office-hours
|
||||
- Strategy, scope, "think bigger", "what should we build" → invoke /plan-ceo-review
|
||||
- Architecture, "does this design make sense" → invoke /plan-eng-review
|
||||
- Design system, brand, "how should this look" → invoke /design-consultation
|
||||
- Design review of a plan → invoke /plan-design-review
|
||||
- Developer experience of a plan → invoke /plan-devex-review
|
||||
- "Review everything", full review pipeline → invoke /autoplan
|
||||
- Bugs, errors, "why is this broken", "wtf", "this doesn't work" → invoke /investigate
|
||||
- Test the site, find bugs, "does this work" → invoke /qa (or /qa-only for report only)
|
||||
- Code review, check the diff, "look at my changes" → invoke /review
|
||||
- Visual polish, design audit, "this looks off" → invoke /design-review
|
||||
- Developer experience audit, try onboarding → invoke /devex-review
|
||||
- Ship, deploy, create a PR, "send it" → invoke /ship
|
||||
- Merge + deploy + verify → invoke /land-and-deploy
|
||||
- Configure deployment → invoke /setup-deploy
|
||||
- Post-deploy monitoring → invoke /canary
|
||||
- Update docs after shipping → invoke /document-release
|
||||
- Weekly retro, "how'd we do" → invoke /retro
|
||||
- Second opinion, codex review → invoke /codex
|
||||
- Safety mode, careful mode, lock it down → invoke /careful or /guard
|
||||
- Restrict edits to a directory → invoke /freeze or /unfreeze
|
||||
- Upgrade gstack → invoke /gstack-upgrade
|
||||
- Save progress, "save my work" → invoke /context-save
|
||||
- Resume, restore, "where was I" → invoke /context-restore
|
||||
- Security audit, OWASP, "is this secure" → invoke /cso
|
||||
- Make a PDF, document, publication → invoke /make-pdf
|
||||
- Launch real browser for QA → invoke /open-gstack-browser
|
||||
- Import cookies for authenticated testing → invoke /setup-browser-cookies
|
||||
- Performance regression, page speed, benchmarks → invoke /benchmark
|
||||
- Review what gstack has learned → invoke /learn
|
||||
- Tune question sensitivity → invoke /plan-tune
|
||||
- Code quality dashboard → invoke /health

/**
|
||||
* View-only session cookie registry for SSE endpoints.
|
||||
*
|
||||
* Why this exists: EventSource cannot send Authorization headers, so
|
||||
* /activity/stream and /inspector/events historically took a `?token=`
|
||||
* query param with the root AUTH_TOKEN. URLs leak through browser history,
|
||||
* referer headers, server logs, crash reports, and refactoring accidents
|
||||
* (Codex's plan-review outside voice called this out). This module issues
|
||||
* a separate short-lived token, scoped to SSE reads only, delivered via
|
||||
* an HttpOnly SameSite=Strict cookie that EventSource can pick up with
|
||||
* `withCredentials: true`.
|
||||
*
|
||||
* Design notes:
|
||||
* - TTL 30 minutes. Long enough for a normal coding session; short enough
|
||||
* that a leaked cookie expires quickly.
|
||||
* - Scope is implicit: validating a cookie only grants read access to
|
||||
* /activity/stream and /inspector/events. The cookie is NEVER valid on
|
||||
* /command, /token, or any mutating endpoint. Matches the
|
||||
* cookie-picker-auth-isolation pattern (prior learning, 10/10 confidence):
|
||||
* cookie-based session tokens must not be valid as scoped tokens.
|
||||
* - In-memory only. No persistence across daemon restarts — extension
|
||||
* re-mints on reconnect.
|
||||
* - Tokens are 32 random bytes (URL-safe base64). 256 bits, unbruteforceable.
