Spec covers 3 improvement areas for codex-review skill pack: 1. Critical bug fixes (5 bugs: phantom AskUserQuestion, nested backticks, $SCOPE undefined, invalid subagent_type, archive step + code editing) 2. Information barrier adoption for security/plan/impl-review 3. VERDICT vocabulary unification (APPROVE|REVISE → CONSENSUS|CONTINUE|STALEMATE) Passed 3-iteration spec review with all CRITICAL/MAJOR issues resolved. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
11-task plan covering 5 critical bug fixes, information barrier adoption for plan/impl/security-review, and VERDICT vocabulary unification. Each task includes exact file targets, verification greps, and commits. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The Smart Default Detection block already handles scope/effort detection and announces the result. Phase 1 Step 1 duplicated this with a call to AskUserQuestion which does not exist in Claude Code. Remove the entire step and renumber remaining Phase 1 steps. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…gent_type Bug 3: pr-review meta.json heredoc used $SCOPE which was never defined, causing literal "$SCOPE" in output. Changed to $BASE_BRANCH which holds the actual base branch value. Bug 4: parallel-review agent spawn blocks included "subagent_type": "code-reviewer" which is not a valid parameter for the Claude Code Agent tool. Removed from all 4 agent JSON blocks and updated the prose description. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

… bypass, and category mismatch
Fixes three issues identified in codex-impl-review:
ISSUE-1: Remove outer fence wrappers from prompt templates in prompts.md
- Security Review Prompt (Round 1) no longer wrapped in backticks
- Round 2+ Prompt (Resume) no longer wrapped in backticks
- Working Tree/Branch/Full mode prompts no longer wrapped in backticks
- Prevents nested fence corruption when {OUTPUT_FORMAT} placeholder
injects output-format.md content (which contains fenced blocks)
ISSUE-2: Update pre-commit hook to check both CONTINUE and STALEMATE
- workflow.md line 575: Changed from grep "VERDICT: CONTINUE" to
grep -qE "VERDICT: (CONTINUE|STALEMATE)"
- Prevents stalemated reviews with unresolved findings from bypassing
security gate
ISSUE-4: Align category taxonomy between template and output-format
- claude-analysis-template.md: Removed 'secrets' category, added 'xxe'
- Now matches the 13 categories defined in output-format.md
- Categories: injection, broken-auth, sensitive-data, xxe, broken-access,
security-config, xss, insecure-deserialization, logging, ssrf,
crypto-failure, insecure-design, vulnerable-components, integrity-failure

Fixes ISSUE-5 from codex-impl-review: The previous fix checked for CONTINUE|STALEMATE but still allowed commits to pass when the verdict was missing, malformed, or unexpected (fail-open). Changed workflow.md line 575 from: if grep -qE "VERDICT: (CONTINUE|STALEMATE)" ... then exit 1 To: if ! grep -qE '^VERDICT: CONSENSUS$' ... then exit 1 Now the gate only passes on explicit CONSENSUS verdict. Any other outcome (CONTINUE, STALEMATE, missing verdict, malformed output) blocks the commit. This is the correct security posture for a pre-commit gate - require explicit pass condition rather than checking for known fail conditions. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
… vocabulary Fixes ISSUE-1, ISSUE-2, ISSUE-3 from second codex-impl-review: ISSUE-1: Pre-commit hook now requires exactly one VERDICT and it must be CONSENSUS - Changed workflow.md line 575 from simple grep to count-based validation - Requires exactly 1 verdict line total AND exactly 1 CONSENSUS verdict - Prevents bypass via multiple verdicts or malformed output - Blocks commits on missing verdict, multiple verdicts, or non-CONSENSUS verdict ISSUE-2: Removed outer fences from example sections in prompts.md - Example Security Finding (lines 228-259) no longer wrapped in backticks - Example Secrets Detection (lines 265-316) no longer wrapped in backticks - Prevents nested fence corruption when examples contain code blocks - Completes the fix started in previous commit ISSUE-3: Updated SKILL.md to use CONSENSUS verdict vocabulary - Line 37: Changed "until APPROVE or stalemate" to "until CONSENSUS verdict or stalemate" - Aligns top-level skill instructions with output-format.md and workflow.md - Completes VERDICT vocabulary unification across security-review skill Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
… fences Fixes ISSUE-1 and ISSUE-2 from third codex-impl-review: ISSUE-1: Pre-commit verdict counting now truly fail-closed - Changed workflow.md line 575 from grep -c (which fails open on zero matches) to awk-based counting with explicit zero normalization - grep -c prints "0" and exits non-zero when no matches found, causing command substitution to capture both grep's "0" and fallback "echo 0" - New approach: awk counts matches and always returns numeric 0 if empty - Added explicit [ -n "$VAR" ] || VAR=0 guards for safety - Now correctly blocks commits on missing review.md, zero verdicts, or non-CONSENSUS verdicts ISSUE-2: Removed outer fences from output-format.md examples - Example: Complete Security Finding (lines 267-325) no longer wrapped - Example: Secrets Detection (lines 331-387) no longer wrapped - Response Format (Round 2+) (lines 393+) no longer wrapped - Completes nested fence elimination across all reference files - Final assembled prompt now has no fence corruption All security-review fixes are now complete: - No nested fence corruption anywhere - Pre-commit gate is truly fail-closed with exact verdict counting - Category taxonomy aligned across all files - VERDICT vocabulary unified to CONSENSUS|CONTINUE|STALEMATE Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…t issues
Fixes ISSUE-1, ISSUE-2, ISSUE-3, ISSUE-4 from fourth codex-impl-review:
ISSUE-1: Clarified Round 1 prompt assembly to exclude Round 2 sections
- workflow.md step 1.8(a): Changed from "Read references/prompts.md as template base"
to "Extract only the Round 1 prompt section from references/prompts.md"
- Explicitly excludes Round 2+ prompt sections to prevent contradictory instructions
- Prevents unresolved {FIXED_ITEMS} and {DISPUTED_ITEMS} placeholders in Round 1
ISSUE-2: Added base branch discovery before validation
- workflow.md: New Step 1 "Detect Scope and Base Branch"
- Auto-detects scope (working-tree, branch, or full)
- For branch mode: discovers base branch via upstream, main, master, or origin/HEAD
- Stores as $BASE_BRANCH for use in validation and prompt assembly
- Moved validation to Step 2, prompt building to Step 3
- Step 1.8(g): Now explicitly replaces {BASE_BRANCH} with $BASE_BRANCH
ISSUE-3: Removed stray closing fence in output-format.md
- Line 402: Removed standalone ``` after Response Format (Round 2+) section
- Opening fence was already removed in Round 4, but closing fence remained
- Completes fence cleanup for Round 2 response format
ISSUE-4: Fixed Status column reference in claude-analysis-template.md
- Line 54: Changed "Update Classification and Status columns" to
"Update Classification column"
- Table only has 3 columns (Claude FINDING, Codex ISSUE, Classification)
- Removes reference to nonexistent Status column
All security-review fixes are now complete and internally consistent.

Fixes ISSUE-1 from fifth codex-impl-review: SKILL.md step 6 had contradictory instructions: - Line 36: "Fix valid vulnerabilities in code; rebut false positives" - Line 61: "Codex reviews only; it does not edit files" - workflow.md: Defines review-only rebuttal/dispute flow Changed step 6 to review-only wording: "Validate findings, prepare rebuttals or severity adjustments, and provide evidence without editing code." This aligns SKILL.md with the review-only contract defined in the Rules section and the detailed workflow in references/workflow.md. All security-review fixes are now complete and internally consistent. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Updated verification steps in plan to reflect actual implementation: - Step 3: Clarified nested fence verification steps - Task 9: Added 5th replacement for APPROVE/REVISE in Phase 2 example Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…l improvements Implements all 12 tasks from Approach A implementation plan: - Fixed 5 bugs across security-review, plan-review, impl-review, pr-review, parallel-review - Added information barrier (Step 2.5) to security-review, plan-review, impl-review - Unified VERDICT vocabulary to CONSENSUS/CONTINUE/STALEMATE across all review skills After 6 rounds of codex-impl-review iterations, all critical issues resolved: - Eliminated nested fence corruption in prompts and output formats - Implemented fail-closed pre-commit security gate with awk-based verdict counting - Aligned category taxonomy across security-review reference files - Clarified prompt assembly to extract only Round 1 sections - Added base branch auto-discovery before validation - Unified review-only behavior across all documentation Total changes: 13 files, +287/-168 lines, 18 commits Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Complete PR description covering: - All 12 planned tasks (5 bug fixes, 3 information barriers, 3 VERDICT unifications) - 6 rounds of additional fixes from codex-impl-review - Final state verification - Files changed summary Ready for PR creation.
…roach A improvements Resolves conflicts between: - origin/main: v13 runner-centric architecture (workflow.md → SKILL.md merge) - local main: Approach A skill improvements (bug fixes, information barrier, VERDICT unification) Conflict resolution: - .gitignore: Combined both .worktrees/ and working documents exclusions - security-review SKILL.md: Kept v13 structure, preserved stdin format rules - workflow.md files: Accepted deletion (merged into SKILL.md in v13) Next steps: Verify Approach A improvements are preserved in v13 SKILL.md structure Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Restores information barrier improvements from Approach A that were lost
during v13 merge when workflow.md files were deleted:
- plan-review: Step 5.5 - Claude independent plan analysis before polling
- impl-review: Step 5.5 - Claude independent code analysis before polling
- security-review: Step 6.5 - Claude independent security analysis before polling
All three skills now include:
- Information barrier phase (MUST complete before polling Codex output)
- Independent FINDING-{N} list formation in working context
- Cross-analysis mapping table (FINDING↔ISSUE) in Apply/Rebut phase
- Classification: Genuine Agreement, Codex-only, Claude-only, Genuine Disagreement
This ensures Claude forms independent judgments before seeing Codex's output,
preventing anchoring bias and enabling genuine peer review.

Changes APPROVE/REVISE/STALEMATE → CONSENSUS/CONTINUE/STALEMATE in: - plan-review SKILL.md - impl-review SKILL.md - security-review SKILL.md This aligns with Approach A's VERDICT vocabulary unification that was already applied to references/output-format.md files but missed in the v13 SKILL.md Final Output tables. Vocabulary meanings: - CONSENSUS: No remaining issues — ready to proceed - CONTINUE: Issues remain that require another review round - STALEMATE: Circular debate — same disputes for 2+ rounds with no progress Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Changed from
APPROVE | REVISEtoCONSENSUS | CONTINUE | STALEMATE:Additional Fixes (6 rounds of codex-impl-review)
After completing the 12 planned tasks, ran adversarial review which identified and fixed:
Round 1-3: Nested Fence Corruption & Gate Bypass
Round 4: Fail-Open Gate & Output Format Fences
Round 5: Prompt Assembly & Base Branch Discovery
Round 6: Review-Only Behavior Alignment
Final State
✅ All nested fence corruption eliminated
✅ Pre-commit gate is truly fail-closed with awk-based counting
✅ Category taxonomy aligned across all security-review files
✅ VERDICT vocabulary unified (CONSENSUS|CONTINUE|STALEMATE)
✅ Prompt assembly extracts only Round 1 section
✅ Base branch discovery happens before validation
✅ All skill files internally consistent
✅ Review-only behavior consistent throughout
Files Changed
Testing
All changes verified through 6 rounds of adversarial review using
/codex-impl-review. Final review found only 2 minor edge cases (branch auto-detection without upstream, Round 2 workflow clarity) which are documented but not blocking.Breaking Changes
None. All changes are internal improvements to skill implementation. The skill invocation interface (
/codex-security-review,/codex-plan-review,/codex-impl-review) remains unchanged.
