From c35997fb0b237bd3feb1317bc6894e1871b37b17 Mon Sep 17 00:00:00 2001 From: Tom Boucher Date: Thu, 16 Apr 2026 17:22:31 -0400 Subject: [PATCH] feat(hooks): add gsd-read-injection-scanner PostToolUse hook (#2201) (#2328) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat: add /gsd-spec-phase — Socratic spec refinement with ambiguity scoring (#2213) Introduces `/gsd-spec-phase ` as an optional pre-step before discuss-phase. Clarifies WHAT a phase delivers (requirements, boundaries, acceptance criteria) with quantitative ambiguity scoring before discuss-phase handles HOW to implement. - `commands/gsd/spec-phase.md` — slash command routing to workflow - `get-shit-done/workflows/spec-phase.md` — full Socratic interview loop (up to 6 rounds, 5 rotating perspectives: Researcher, Simplifier, Boundary Keeper, Failure Analyst, Seed Closer) with weighted 4-dimension ambiguity gate (≤ 0.20 to write SPEC.md) - `get-shit-done/templates/spec.md` — SPEC.md template with falsifiable requirements (Current/Target/Acceptance per requirement), Boundaries, Acceptance Criteria, Ambiguity Report, and Interview Log; includes two full worked examples - `get-shit-done/workflows/discuss-phase.md` — new `check_spec` step detects `{padded_phase}-SPEC.md` at startup; displays "Found SPEC.md — N requirements locked. Focusing on implementation decisions."; `analyze_phase` respects `spec_loaded` flag to skip "what/why" gray areas; `write_context` emits `` section with boundary summary and canonical ref to SPEC.md - `docs/ARCHITECTURE.md` — update command/workflow counts (74→75, 71→72) Closes #2213 Co-Authored-By: Claude Sonnet 4.6 * feat(hooks): add gsd-read-injection-scanner PostToolUse hook (#2201) Adds a new PostToolUse hook that scans content returned by the Read tool for prompt injection patterns, including four summarisation-specific patterns (retention-directive, permanence-claim, etc.) that survive context compression. Defense-in-depth for long GSD sessions where the context summariser cannot distinguish user instructions from content read from external files. - Advisory-only (warns without blocking), consistent with gsd-prompt-guard.js - LOW severity for 1-2 patterns, HIGH for 3+ - Inlined pattern library (hook independence) - Exclusion list: .planning/, REVIEW.md, CHECKPOINT, security docs, hook sources - Wired in install.js as PostToolUse matcher: Read, timeout: 5s - Added to MANAGED_HOOKS for staleness detection - 19 tests covering all 13 acceptance criteria (SCAN-01–07, EXCL-01–06, EDGE-01–06) Closes #2201 Co-Authored-By: Claude Sonnet 4.6 * fix(ci): add read-injection-scanner files to prompt-injection-scan allowlist Test payloads in tests/read-injection-scanner.test.cjs and inlined patterns in hooks/gsd-read-injection-scanner.js legitimately contain injection strings. Add both to the CI script allowlist to prevent false-positive failures. Co-Authored-By: Claude Sonnet 4.6 * fix(test): assert exitCode, stdout, and signal explicitly in EDGE-05 Addresses CodeRabbit feedback: the success path discarded the return value so a malformed-JSON input that produced stdout would still pass. Now captures and asserts all three observable properties.
