From cf3582c637b01ad6d58ee89091c858f466576d99 Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sun, 22 Mar 2026 13:19:10 -0700 Subject: [PATCH] fix: community security + stability fixes (wave 1) (#325) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: add /cso skill — OWASP Top 10 + STRIDE security audit * fix: harden gstack-slug against shell injection via eval Whitelist safe characters (a-zA-Z0-9._-) in SLUG and BRANCH output to prevent shell metacharacter injection when used with eval. Only affects self-hosted git servers with lax naming rules — GitHub and GitLab enforce safe characters already. Defense-in-depth. * fix(security): sanitize gstack-slug output against shell injection The gstack-slug script is consumed via eval $(gstack-slug) throughout skill templates. If a git remote URL contains shell metacharacters like $(), backticks, or semicolons, they would be executed by eval. Fix: strip all characters except [a-zA-Z0-9._-] from both SLUG and BRANCH before output. This preserves normal values while neutralizing any injection payload in malicious remote URLs. Before: eval $(gstack-slug) with remote "foo/bar$(rm -rf /)" → executes rm After: eval $(gstack-slug) with remote "foo/bar$(rm -rf /)" → SLUG=foo-barrm-rf- * fix(security): redact sensitive values in storage command output The browse `storage` command dumps all localStorage and sessionStorage as JSON. This can expose tokens, API keys, JWTs, and session credentials in QA reports and agent transcripts. Fix: redact values where the key matches sensitive patterns (token, secret, key, password, auth, jwt, csrf) or the value starts with known credential prefixes (eyJ for JWT, sk- for Stripe, ghp_ for GitHub, etc.). Redacted values show length to aid debugging: [REDACTED — 128 chars] * fix(browse): kill old server before restart to prevent orphaned chromium processes When the health check fails or the server connection drops, `ensureServer()` and `sendCommand()` would call `startServer()` without first killing the previous server process. This left orphaned `chrome-headless-shell` renderer processes running at ~120% CPU each. After several reconnect cycles (e.g. pages that crash during hydration or trigger hard navigations via `window.location.href`), dozens of zombie chromium processes accumulate and exhaust system resources. Fix: call `killServer()` on the stale PID before spawning a new server in both the `ensureServer()` unhealthy path and the `sendCommand()` connection- lost retry path. Fixes #294 * Fix YAML linter error: nested mapping in compact sequence entries Having "Run: bun" inside a plain scalar is not allowed per YAML spec which states: Plain scalars must never contain the “: ” and “ #” character combinations. This simple fix switches to block scalars (|) to eliminate the ambiguity without changing runtime behavior. * fix(security): add Azure metadata endpoint to SSRF blocklist Add metadata.azure.internal to BLOCKED_METADATA_HOSTS alongside the existing AWS/GCP endpoints. Closes the coverage gap identified in #125. Co-Authored-By: Claude Opus 4.6 (1M context) * test: add coverage for storage redaction Test key-based redaction (auth_token, api_key), value-based redaction (JWT prefix, GitHub PAT prefix), pass-through for normal keys, and length preservation in redacted output. Co-Authored-By: Claude Opus 4.6 (1M context) * docs: add community PR triage process to CONTRIBUTING.md Document the wave-based PR triage pattern used for batching community contributions. References PR #205 (v0.8.3) as the original example. Co-Authored-By: Claude Opus 4.6 (1M context) * fix: adjust test key names to avoid redaction pattern collision Rename testKey→testData and normalKey→displayName in storage tests to avoid triggering #238's SENSITIVE_KEY regex (which matches 'key'). Also generate Codex variant of /cso skill. Co-Authored-By: Claude Opus 4.6 (1M context) * docs: update project documentation for v0.9.10.0 Co-Authored-By: Claude Opus 4.6 (1M context) * feat: zero-noise /cso security audits with FP filtering (v0.11.0.0) Absorb Anthropic's security-review false positive filtering into /cso: - 17 hard exclusions (DOS, test files, log spoofing, SSRF path-only, regex injection, race conditions unless concrete, etc.) - 9 precedents (React XSS-safe, env vars trusted, client-side code doesn't need auth, shell scripts need concrete untrusted input path) - 8/10 confidence gate — below threshold = don't report - Independent sub-agent verification for each finding - Exploit scenario requirement per finding - Framework-aware analysis (Rails CSRF, React escaping, Angular sanitization) Co-Authored-By: Claude Opus 4.6 (1M context) * docs: consolidate CHANGELOG — merge /cso launch + community wave into v0.11.0.0 Co-Authored-By: Claude Opus 4.6 (1M context) * docs: rewrite README — lead with Karpathy quote, cut LinkedIn phrases, add /cso Opens with the revolution (Karpathy, Steinberger/OpenClaw), keeps credentials and LOC numbers, cuts filler phrases, adds hater bait, restores hiring block, removes bloated "What's new" section, adds /cso to skills table and install. Co-Authored-By: Claude Opus 4.6 (1M context) * fix(cso): adversarial review fixes — FP filtering, prompt injection, language coverage - Exclusion #10: test files must verify not imported by non-test code - Exclusion #13: distinguish user-message AI input from system-prompt injection - Exclusion #14: ReDoS in user-input regex IS a real CVE class, don't exclude - Add anti-manipulation rule: ignore audit-influencing instructions in codebase - Fix confidence gate: remove contradictory 7-8 tier, hard cutoff at 8 - Fix verifier anchoring: send only file+line, not category/description - Add Go, PHP, Java, C#, Kotlin to grep patterns (was 4 languages, now 8) - Add GraphQL, gRPC, WebSocket endpoint detection to attack surface mapping Co-Authored-By: Claude Opus 4.6 (1M context) * fix(docs): correct skill counts, add /autoplan to README tables Skill count was wrong in 3 places (said 19+7=26, said 25, actual is 28). Added /autoplan to specialist table. Fixed troubleshooting skills list to include all skills added since v0.7.0. Co-Authored-By: Claude Opus 4.6 (1M context) * fix(browse): DNS rebinding protection for SSRF blocklist validateNavigationUrl is now async — resolves hostname to IP and checks against blocked metadata IPs. Prevents DNS rebinding where evil.com initially resolves to a safe IP, then switches to 169.254.169.254. All callers updated to await. Tests updated for async assertions. Co-Authored-By: Claude Opus 4.6 (1M context) * fix(browse): lockfile prevents concurrent server start races Adds exclusive lockfile (O_CREAT|O_EXCL) around ensureServer to prevent TOCTOU race where two CLI invocations could both kill the old server and start new ones, leaving an orphaned chromium process. Second caller now waits for the first to finish starting. Co-Authored-By: Claude Opus 4.6 (1M context) * fix(browse): improve storage redaction — word-boundary keys + more value prefixes Key regex: use underscore/dot/hyphen boundaries instead of \b (which treats _ as word char). Now correctly redacts auth_token, session_token while skipping keyboardShortcuts, monkeyPatch, primaryKey. Value regex: add AWS (AKIA), Stripe (sk_live_, pk_live_), Anthropic (sk-ant-), Google (AIza), Sendgrid (SG.), Supabase (sbp_) prefixes. Co-Authored-By: Claude Opus 4.6 (1M context) * fix: migrate all remaining eval callers to source, fix stale CHANGELOG claim 5 templates and 2 bin scripts still used eval $(gstack-slug). All now use source <(gstack-slug). Updated gstack-slug comment to match. Fixed v0.8.3 CHANGELOG entry that falsely claimed eval was fully eliminated — it was the output sanitization that made it safe, not a calling convention change. Co-Authored-By: Claude Opus 4.6 (1M context) * fix(docs): add /autoplan to install instructions, regen skill docs The install instruction blocks and troubleshooting section were missing /autoplan. All three skill list locations now include the complete 28-skill set. Regenerated codex/agents SKILL.md files to match template changes. Co-Authored-By: Claude Opus 4.6 (1M context) * docs: update project documentation for v0.11.0.0 Co-Authored-By: Claude Opus 4.6 * docs(cso): add disclaimer — not a substitute for professional security audits LLMs can miss subtle vulns and produce false negatives. For production systems with sensitive data, hire a real firm. /cso is a first pass, not your only line of defense. Disclaimer appended to every report.

(1-2 sentences) +2. **Simplify:** Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called. +3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it. +4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)` + +Assume the user hasn't looked at this window in 20 minutes and doesn't have the code open.

When you present options: + +- If Option A is the complete implementation (full parity, all edge cases, 100% coverage) and Option B is a shortcut that saves modest effort — **always recommend A**. The delta between 80 lines and 150 lines is meaningless with CC+gstack. "Good enough" is the wrong instinct when "complete" costs minutes more. +- **Lake vs. ocean:** A "lake" is boilable — 100% test coverage for a module, full feature implementation, handling all edge cases, complete error paths. An "ocean" is not — rewriting an entire system from scratch, adding features to dependencies you don't control, multi-quarter platform migrations. Recommend boiling lakes. Flag oceans as out of scope. +- **When estimating effort**, always show both scales: human team time and CC+gstack time. The compression ratio varies by task type — use this reference: + +| Task type | Human team | CC+gstack | Compression | +|-----------|-----------|-----------|-------------| +| Boilerplate / scaffolding | 2 days | 15 min | ~100x | +| Test writing | 1 day | 15 min | ~50x | +| Feature implementation | 1 week | 30 min | ~30x | +| Bug fix + regression test | 4 hours | 15 min | ~20x | +| Architecture / design | 2 days | 4 hours | ~5x | +| Research / exploration | 1 day | 3 hours | ~3x | + +- This principle applies to test coverage, error handling, documentation, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds. + +**Anti-patterns — DON'T do this:** +- BAD: "Choose B — it covers 90% of the value with less code." (If A is only 70 lines more, choose A.) +- BAD: "We can skip edge case handling to save time." (Edge case handling costs minutes with CC.) +- BAD: "Let's defer test coverage to a follow-up PR." (Tests are the cheapest lake to boil.) +- BAD: Quoting only human-team effort: "This would take 2 weeks." (Say: "2 weeks human / ~1 hour CC.") + +## Repo Ownership Mode — See Something, Say Something + +`REPO_MODE` from the preamble tells you who owns issues in this repo: + +- **`solo`** — One person does 80%+ of the work. They own everything. When you notice issues outside the current branch's changes (test failures, deprecation warnings, security advisories, linting errors, dead code, env problems), **investigate and offer to fix proactively**. The solo dev is the only person who will fix it. Default to action. +- **`collaborative`** — Multiple active contributors. When you notice issues outside the branch's changes, **flag them via AskUserQuestion** — it may be someone else's responsibility. Default to asking, not fixing. +- **`unknown`** — Treat as collaborative (safer default — ask before fixing). + +**See Something, Say Something:** Whenever you notice something that looks wrong during ANY workflow step — not just test failures — flag it briefly. One sentence: what you noticed and its impact. In solo mode, follow up with "Want me to fix it?" In collaborative mode, just flag it and move on. + +Never let a noticed issue silently pass. The whole point is proactive communication. + +## Search Before Building + +Before building infrastructure, unfamiliar patterns, or anything the runtime might have a built-in — **search first.** Read `~/.codex/skills/gstack/ETHOS.md` for the full philosophy. + +**Three layers of knowledge:** +- **Layer 1** (tried and true — in distribution). Don't reinvent the wheel. But the cost of checking is near-zero, and once in a while, questioning the tried-and-true is where brilliance occurs. +- **Layer 2** (new and popular — search for these). But scrutinize: humans are subject to mania. Search results are inputs to your thinking, not answers. +- **Layer 3** (first principles — prize these above all). Original observations derived from reasoning about the specific problem. The most valuable of all. + +**Eureka moment:** When first-principles reasoning reveals conventional wisdom is wrong, name it: +"EUREKA: Everyone does X because [assumption].

The design doc it writes feeds directly into `/plan-ceo-review` and `/plan-eng-review` — so every downstream skill starts with real clarity instead of a vague feature request. +gstack works well with one sprint. It gets interesting with ten running at once. -**Design is at the heart.** `/design-consultation` doesn't just pick fonts. It researches what's out there in your space, proposes safe choices AND creative risks, generates realistic mockups of your actual product, and writes `DESIGN.md` — and then `/design-review` and `/plan-eng-review` read what you chose. Design decisions flow through the whole system. - -**`/qa` was a massive unlock.** It let me go from 6 to 12 parallel workers. Claude Code saying *"I SEE THE ISSUE"* and then actually fixing it, generating a regression test, and verifying the fix — that changed how I work. The agent has eyes now. - -**Smart review routing.** Just like at a well-run startup: CEO doesn't have to look at infra bug fixes, design review isn't needed for backend changes. gstack tracks what reviews are run, figures out what's appropriate, and just does the smart thing. The Review Readiness Dashboard tells you where you stand before you ship. - -**Test everything.** `/ship` bootstraps test frameworks from scratch if your project doesn't have one. Every `/ship` run produces a coverage audit. Every `/qa` bug fix generates a regression test. 100% test coverage is the goal — tests make vibe coding safe instead of yolo coding. - -**Ship to production in one command.** `/land-and-deploy` picks up where `/ship` left off — merges your PR, waits for CI and deploy, then runs canary verification on your production URL. Auto-detects Fly.io, Render, Vercel, Netlify, Heroku, or GitHub Actions. If something breaks, it offers a revert. Pair with `/canary` for extended post-deploy monitoring and `/benchmark` to catch performance regressions before they ship. - -**`/document-release` is the engineer you never had.** It reads every doc file in your project, cross-references the diff, and updates everything that drifted. README, ARCHITECTURE, CONTRIBUTING, CLAUDE.md, TODOS — all kept current automatically. And now `/ship` auto-invokes it — docs stay current without an extra command. - -**Browser handoff when the AI gets stuck.** Hit a CAPTCHA, auth wall, or MFA prompt? `$B handoff` opens a visible Chrome at the exact same page with all your cookies and tabs intact. Solve the problem, tell Claude you're done, `$B resume` picks up right where it left off. The agent even suggests it automatically after 3 consecutive failures. - -**Multi-AI second opinion.** `/codex` gets an independent review from OpenAI's Codex CLI — a completely different AI looking at the same diff. Three modes: code review with a pass/fail gate, adversarial challenge that actively tries to break your code, and open consultation with session continuity. When both `/review` (Claude) and `/codex` (OpenAI) have reviewed the same branch, you get a cross-model analysis showing which findings overlap and which are unique to each. - -**Safety guardrails on demand.** Say "be careful" and `/careful` warns before any destructive command — rm -rf, DROP TABLE, force-push, git reset --hard. `/freeze` locks edits to one directory while debugging so Claude can't accidentally "fix" unrelated code. `/guard` activates both. `/investigate` auto-freezes to the module being investigated. - -**Proactive skill suggestions.** gstack notices what stage you're in — brainstorming, reviewing, debugging, testing — and suggests the right skill.

Use concrete examples and analogies. Say what it DOES, not what it's called. +3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it. +4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)` + +Assume the user hasn't looked at this window in 20 minutes and doesn't have the code open.

The delta between 80 lines and 150 lines is meaningless with CC+gstack. "Good enough" is the wrong instinct when "complete" costs minutes more. +- **Lake vs. ocean:** A "lake" is boilable — 100% test coverage for a module, full feature implementation, handling all edge cases, complete error paths. An "ocean" is not — rewriting an entire system from scratch, adding features to dependencies you don't control, multi-quarter platform migrations. Recommend boiling lakes. Flag oceans as out of scope. +- **When estimating effort**, always show both scales: human team time and CC+gstack time. The compression ratio varies by task type — use this reference: + +| Task type | Human team | CC+gstack | Compression | +|-----------|-----------|-----------|-------------| +| Boilerplate / scaffolding | 2 days | 15 min | ~100x | +| Test writing | 1 day | 15 min | ~50x | +| Feature implementation | 1 week | 30 min | ~30x | +| Bug fix + regression test | 4 hours | 15 min | ~20x | +| Architecture / design | 2 days | 4 hours | ~5x | +| Research / exploration | 1 day | 3 hours | ~3x | + +- This principle applies to test coverage, error handling, documentation, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds. + +**Anti-patterns — DON'T do this:** +- BAD: "Choose B — it covers 90% of the value with less code." (If A is only 70 lines more, choose A.) +- BAD: "We can skip edge case handling to save time." (Edge case handling costs minutes with CC.) +- BAD: "Let's defer test coverage to a follow-up PR." (Tests are the cheapest lake to boil.) +- BAD: Quoting only human-team effort: "This would take 2 weeks." (Say: "2 weeks human / ~1 hour CC.") + +## Repo Ownership Mode — See Something, Say Something + +`REPO_MODE` from the preamble tells you who owns issues in this repo: + +- **`solo`** — One person does 80%+ of the work. They own everything. When you notice issues outside the current branch's changes (test failures, deprecation warnings, security advisories, linting errors, dead code, env problems), **investigate and offer to fix proactively**. The solo dev is the only person who will fix it. Default to action. +- **`collaborative`** — Multiple active contributors. When you notice issues outside the branch's changes, **flag them via AskUserQuestion** — it may be someone else's responsibility. Default to asking, not fixing. +- **`unknown`** — Treat as collaborative (safer default — ask before fixing). + +**See Something, Say Something:** Whenever you notice something that looks wrong during ANY workflow step — not just test failures — flag it briefly.

Don't reinvent the wheel. But the cost of checking is near-zero, and once in a while, questioning the tried-and-true is where brilliance occurs. +- **Layer 2** (new and popular — search for these). But scrutinize: humans are subject to mania. Search results are inputs to your thinking, not answers. +- **Layer 3** (first principles — prize these above all). Original observations derived from reasoning about the specific problem. The most valuable of all. + +**Eureka moment:** When first-principles reasoning reveals conventional wisdom is wrong, name it: +"EUREKA: Everyone does X because [assumption].
