* feat(#3415): ship local/no-unbounded-quantifier, burn down ReDoS class Phase 4 of epic #3212 (ADR-3212 §5/§7, the final phase). New rule flags an unbounded */+/{n,} quantifier over a broad character class ([\s\S], dotAll ., or a 1-2-unit negated class like [^\n]/[^)\n] — the exact #2128-fixed shape) applied to a regex whose match target is data-flow-traced to readFileSync content. eslint-rules/lib/readfilesync-trace.cjs extracts the data-flow tracer shared with no-crlf-fragile-split (Phase 2) rather than a second copy — no-crlf-fragile-split refactored onto it with zero behavior change, parity-tested. Real triage, not 798 mechanical edits: the ADR's census (2026-08-08) screened every unbounded quantifier in the tree unscoped. Correctly scoped to readFileSync-derived content (matching Phase 2's own G2/G3 scoping), the rule found 162 real hits across two detection waves — the second wave (93) surfaced only after a genuine off-by-one bug in this rule's own first draft was caught while writing its RuleTester tests and fixed (the bug silently missed every directly-quantified [\s\S]* with no gap before the quantifier — exactly the class this rule exists to catch). 3 hits landed in production src/ (commands.cts, milestone.cts, roadmap.cts) and were each empirically timed against adversarial input (matching #2128's own measured-not-assumed precedent) — all confirmed linear-time/benign, left unbounded with a measured-evidence comment rather than mechanically bounded. The remaining 159 are test-file fixture parsing (test-author-controlled, fixed-size content, not adversarial input) — each suppressed with a specific, non-generic reason. Zero functional behavior changed anywhere in this diff. tests/no-pending-3212-markers.test.cjs locks the epic's own closing invariant (ADR §7: "assert zero pending #3212 markers remain") — ground truth confirmed trivially true today (no phase left any such marker behind), now regression-locked going forward. Design: .gsd/phase/chore-3415-prohibition-with-teeth/40-design.md Test matrix: .gsd/phase/chore-3415-prohibition-with-teeth/50-test-matrix.md Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3415): correct rule category mislabel, add CI test-scope entry An orthogonal Standards-axis review found eslint-rules/no-unbounded-quantifier.cjs mistakenly carried meta.docs.category: 'Portability', copied from a sibling rule without realizing what that implied: docs/contributing/cross-platform- portability-rules.md governs an ADR-1703 rule family under a hard "zero escape hatches" contract (tests/portability-rule-disable-ban.test.cjs's PROTECTED_RULES bans eslint-disable for those rules entirely). This rule is not part of that family — it's ADR-3212 (ReDoS/CWE-1333), a different epic — and its eslint-disable-next-line suppressions (159 of them, added earlier this same phase after empirical benign-verification) are an intentional, correct design, not a bypass. Corrected to category: 'Best Practices', matching the actual precedent (no-adhoc-regex-escape.cjs, Phase 1 of the same epic, which is also correctly outside PROTECTED_RULES), and the rule's own docstring now states this explicitly so a future reader doesn't have to re-derive it. Also registers a new scripts/ci-test-scope.cjs bucket so editing this rule or the shared eslint-rules/lib/readfilesync-trace.cjs helper re-runs their own test suites under targeted CI selection — was previously unregistered and invisible to that fast-path (this PR's own gsd-test checkpoint runs the full suite regardless, so this only affects future narrowly-scoped PRs). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3415): bound no-unbounded-quantifier's own scanner (CWE-1333, ironic) Security review found the rule meant to catch algorithmic-complexity bugs had one of its own: hasUnboundedBroadQuantifier's negated-class inner scan walked from each `[^` occurrence to the next `]` (or EOF) with no bound, while the outer loop only ever advanced by one character — O(n²) total work on a pattern with many unclosed `[^` runs. Runs unconditionally inside checkPattern on any `new RegExp('literal string')` argument in any linted file, before the (cheap) readFileSync data-flow gate — so a single crafted string literal, no valid regex syntax required, could make `npm run lint` / CI hang. Empirically confirmed both the bug and the fix: pre-fix, n=4000/8000/ 16000/32000 chars took 30.8/115.6/463.8/1874.3ms (~4x work per 2x n, quadratic); extrapolated, the 300000-char repro from the finding would run ~165s. Post-fix (bail the inner scan once units exceeds the rule's own 1-2-unit scope, rather than continuing to hunt for a closing `]`), the same 300000-char input runs in 8.7ms via the real rule module, independently reconfirmed at 18ms via a fresh Linter.verify() call. New regression row in tests/no-unbounded-quantifier.rule.test.cjs asserts the RuleTester run on a 50000-char adversarial pattern completes and returns a defined result — no wall-clock assertion (CLAUDE.md Clock Seams / local/no-elapsed-assertion). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> * fix(#3415): triage 3 new sites, re-raise ceiling after upstream batch next merged 12 more PRs during this PR's review. Two consequences: - tests/edit-phase.test.cjs (fix #3262, unrelated) added 3 new content.match(/<tag>([\s\S]*?)<\/tag>/) reads of this repo's own workflow .md content — the same Class A pattern as the ~159 sites already triaged elsewhere in this PR. Suppressed with the same established reason. - lint-allow-test-rule-refs' ratchet ceiling needed re-raising again (301 -> 303) for the same reason as the two prior bumps: organic growth from unrelated, already-reviewed PRs landing concurrently, not a defect in this branch's own diff.

GSD Core
Git. Ship. Done.
English · Português · 简体中文 · 日本語 · 한국어
A light-weight meta-prompting, context engineering, and spec-driven development system for Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more.
What is GSD Core
GSD Core is a context-engineering and spec-driven development framework that drives AI coding agents (Claude Code, Codex, Antigravity CLI, Kimi CLI, Copilot, Cursor, and more) through a disciplined phase loop. It solves context rot — the quality degradation that accumulates as an AI fills its context window — by running all heavy research, planning, and execution work in fresh-context subagents while keeping your main session lean.
How it works
Each milestone repeats the same five-step loop, one phase at a time:
- Discuss — capture implementation decisions before anything is planned
- Plan — research, decompose, and verify the plan fits a fresh context window
- Execute — run plans in parallel waves; each executor starts with a clean 200k-token context
- Verify — walk through what was built; diagnose and fix before declaring done
- Ship — create the PR, archive the phase, repeat for the next one
Quickstart
npx @opengsd/gsd-core@latest
The installer prompts for your runtime (Claude Code, OpenCode, Antigravity CLI, Kimi CLI, Kilo, Codex, Copilot, Cursor, Windsurf, and more) and whether to install globally or locally. The installer is required for cross-runtime compatibility — do not copy files from agents/ or commands/ directly.
On another runtime or without Node.js? See Install on your runtime.
Once installed, start a new project or onboard an existing repo:
/gsd-new-project # greenfield project
/gsd-onboard # existing codebase

Why it works
Most AI-coding setups fail at scale because context bloat silently degrades output quality, there is no shared memory between sessions, and nothing verifies that code actually works. GSD Core solves all three: heavy work runs in fresh subagents, structured artifacts like STATE.md and CONTEXT.md survive session boundaries, and the verify step walks through what was built and generates fix plans before a phase is declared done. See docs/explanation/context-engineering.md for the full reasoning.
