Add three sections for contributor onboarding: template placeholder reference (all 10 resolvers), browse subsystem architecture (daemon model, state file, command dispatch, ref system, logging), and test infrastructure internals (touchfiles, session-runner, eval-store, llm-judge, observability). Add standard header.
Syncs boinger/gstack with garrytan/gstack upstream. Includes new skills (freeze, careful, guard, investigate, office-hours, codex, unfreeze), Gemini CLI support, telemetry infrastructure, Node-compatible server bundle, and Codex CLI e2e tests.
- Add to ALL_SKILLS in gen-skill-docs.test.ts - Add to all 4 preamble validation arrays in skill-validation.test.ts - Add structural validation tests: checklist categories, [QUICK] tags, report template sections, language patterns, phase markers - Add LLM-judge eval for SKILL.md quality scoring - Add E2E eval for --quick mode smoke test - Add touchfile dependencies for diff-based test selection
- README: skills table, count (thirteen → fourteen), install prompts, add-to-project prompt, troubleshooting snippet - docs/skills.md: table entry + deep dive section with philosophy, modes, health scoring, when-to-use comparison table, and example - CHANGELOG: v0.6.5.0 entry
After the audit report, the skill now offers four options: - Show all findings inline - Fix selected findings (pick by number, creates atomic commits) - Quick fixes only (mechanical fixes like .gitignore, exception narrowing, missing timeouts — no judgment calls) - Done (review report later) This bridges the gap between "here's what's wrong" and "let me fix it" without requiring a separate session. The audit phase remains read-only; fix mode lifts the constraint after user opt-in.
The "Fix selected findings" path now distinguishes between mechanical fixes (apply directly) and substantive fixes (recommend /plan-eng-review and optionally /plan-ceo-review before executing). This follows the gstack philosophy of using the review pipeline for quality assurance on anything beyond trivial changes.
…sity Two issues from live testing: 1. Substantive fixes now require an explicit AskUserQuestion offering /plan-eng-review before implementation. Previous recommend language was treated as optional. Now mandatory step with A/B/C options. 2. Checklist pattern execution now uses files_with_matches mode instead of content mode for Grep. Prevents 3000+ line dumps from broad regex matches into the conversation.
Plan mode restricts Write to the plan file path. The audit report needs to write to ~/.gstack/. Added Phase 4.0 requiring ExitPlanMode before any file writes, with fallback messaging if it cannot exit.
…tern Replaces the ambiguous multi-choice next-steps prompt with the same deterministic review chaining pattern used by /plan-ceo-review and /plan-eng-review. Key changes: - Findings are pre-classified as mechanical vs substantive - Default recommendation routes substantive fixes through /plan-eng-review - Mechanical fixes are applied immediately with atomic commits - AskUserQuestion presents concrete options based on finding classification - Section renamed to 'Next Steps - Review Chaining' matching other skills
Two fixes from plan-mode testing: 1. Report writing now uses Bash heredoc instead of Write tool. Plan mode restricts Write to plan files, but Bash is unrestricted. This bypasses the plan mode issue entirely. 2. Added absolute rule 14 banning content-mode Grep during checklist execution. Fixed the defer-in-loops regex in patterns.md which was a multiline pattern that matched entire files (3000+ lines).
The plan file banner now recommends the appropriate review path: - Scope/product decisions → /plan-ceo-review first, then /plan-eng-review - Implementation-level fixes → /plan-eng-review directly This matches how other gstack skills chain reviews based on the nature of the work.
…ve work The key architectural insight: plan mode owns the session after the plan file is written. So mechanical fixes must be applied BEFORE writing the plan. Then 'Ready to code?' only covers substantive fixes, and the banner correctly says to run /plan-eng-review first. Previously both mechanical and substantive fixes were in the plan, making 'Ready to code?' ambiguous.
Fundamental reframe: the audit IS planning. Phases 1-3 are read-only research (compatible with plan mode). Phase 4 produces two outputs: the archival report (to ~/.gstack/ via Bash) and the fix plan (to the plan file). 'Ready to code?' means 'execute this fix plan.' The plan file now has two parts: - Part 1: Mechanical fixes (apply immediately on execution) - Part 2: Substantive fixes (banner recommends /plan-eng-review first) Removes all plan-mode-fighting instructions. No more ExitPlanMode, no more 'do NOT write to plan files.' The plan file is the correct output — this is how other gstack skills work.
After the fix plan is written, the skill now presents an AskUserQuestion offering to run /plan-eng-review or /plan-ceo-review directly. The user can say yes, make changes, or accept as-is. This replaces the previous approach of ending with 'Ready to code?' which required the user to manually type /plan-eng-review. Now the skill escorts the user to the next step, matching how /plan-ceo-review chains to /plan-eng-review.
Regenerate .agents/skills/ for both codebase-audit (template updates) and retro (upstream v0.9.4.1 fix propagation).
- Swap rules 13/14 in template (14 appeared before 13) - Remove "project you've never seen before" framing — the audit works on any codebase regardless of familiarity - Lead CHANGELOG with fix pipeline, not just report generation
The first real-world run of /codebase-audit against gstack surfaced bugs in the skill template itself: - Step 1.2 ls -la exits non-zero when build files are missing, which cascades and cancels all parallel tool calls. Add || true. - Step 4.1 uses cat via Bash to read the report template, contradicting Key Rule 12 (always use the Read tool). Replace with Read instruction. - Step 1.3 LOC count includes non-code files (images, JSON, lockfiles), inflating the count and triggering incorrect Large codebase scoping. Filter by common source code extensions. - Baseline finding IDs were specified as SHA256 hashes but no mechanism was provided to compute them, making regression comparison impossible. Add shasum snippet.

Audit → fix plan → review → implement. One command.
/codebase-auditreads a codebase cold, produces a structured report (health score, findings by severity, architecture diagram), writes a fix plan, and chains into/plan-eng-reviewfor substantive items. Full pipeline in one session.Where
/reviewchecks a diff, this checks everything — and goes further by splitting findings into mechanical fixes (apply now) and substantive fixes (review first).Run it against any codebase — one you inherited, one you wrote last month, or one you just cloned.
Tested against 4 production codebases across 4 languages:
Each test ran the full pipeline: audit → AskUserQuestion → user selects
/plan-eng-review→ eng review runs in the same session. The confvis run went further: mechanical fixes applied, lint clean, all 29 test packages pass.Design decisions
Plan mode native. The audit is "planning-for-a-plan." Phases 1-3 are read-only research. Phase 4 writes the report via Bash heredoc (bypasses plan mode's Write restriction) and produces the fix plan as the plan file. No fighting the tool — the plan file IS the natural output.
Review chaining. After the plan is written, AskUserQuestion offers
/plan-eng-review,/plan-ceo-review, accept as-is, or edit first. The Skill tool is invoked immediately on selection — before plan mode's "Ready to code?" can intercept. Mechanical fixes (Part 1) can be applied directly; substantive fixes (Part 2) route through the review pipeline.Health score calibration. 100-point scale: critical=-25, important=-10, notable=-3, opportunity=0. Original weights (-25/-15/-5) scored a well-built Go CLI at 30/100. Recalibrated so the same codebase scores 77/100 — matches the intuition of "solid code with some gaps."
Grep discipline. Phase 3 uses
files_with_matchesmode exclusively. Content-mode grep on broad patterns matched entire files and flooded context. Rule 14 bans content-mode during checklist execution.Knowledge cutoff awareness. Rule 11 prevents false positives from flagging valid-but-unfamiliar versions (e.g., Go 1.25) as nonexistent.
