Audit Nyquist validation gaps for a completed phase. Generate missing tests. Update VALIDATION.md.

0. Initialize

INIT=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" init phase-op "${PHASE_ARG}")
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi

Parse: phase_dir, phase_number, phase_name, phase_slug, padded_phase.

AUDITOR_MODEL=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" resolve-model gsd-nyquist-auditor --raw)
NYQUIST_CFG=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" config-get workflow.nyquist_validation --raw)

If NYQUIST_CFG is false: exit with "Nyquist validation is disabled. Enable via /gsd:settings."

1. Detect Input State

VALIDATION_FILE=$(ls "${PHASE_DIR}"/*-VALIDATION.md 2>/dev/null | head -1)
SUMMARY_FILES=$(ls "${PHASE_DIR}"/*-SUMMARY.md 2>/dev/null)

• State A (VALIDATION_FILE non-empty): Audit existing
• State B (VALIDATION_FILE empty, SUMMARY_FILES non-empty): Reconstruct from artifacts
• State C (SUMMARY_FILES empty): Exit — "Phase {N} not executed. Run /gsd:execute-phase {N} ${GSD_WS} first."

2. Discovery

2a. Read Phase Artifacts

Read all PLAN and SUMMARY files. Extract: task lists, requirement IDs, key-files changed, verify blocks.

2b. Build Requirement-to-Task Map

Per task: { task_id, plan_id, wave, requirement_ids, has_automated_command }

2c. Detect Test Infrastructure

State A: Parse from existing VALIDATION.md Test Infrastructure table. State B: Filesystem scan:

find . -name "pytest.ini" -o -name "jest.config.*" -o -name "vitest.config.*" -o -name "pyproject.toml" 2>/dev/null | head -10
find . \( -name "*.test.*" -o -name "*.spec.*" -o -name "test_*" \) -not -path "*/node_modules/*" 2>/dev/null | head -40

2d. Cross-Reference

Match each requirement to existing tests by filename, imports, test descriptions. Record: requirement → test_file → status.

3. Gap Analysis

Classify each requirement:

Status	Criteria
COVERED	Test exists, targets behavior, runs green
PARTIAL	Test exists, failing or incomplete
MISSING	No test found

Build: { task_id, requirement, gap_type, suggested_test_path, suggested_command }

No gaps → skip to Step 6, set nyquist_compliant: true.

4. Present Gap Plan

Call AskUserQuestion with gap table and options:

1. "Fix all gaps" → Step 5
2. "Skip — mark manual-only" → add to Manual-Only, Step 6
3. "Cancel" → exit

5. Spawn gsd-nyquist-auditor

Task(
  prompt="Read ~/.claude/agents/gsd-nyquist-auditor.md for instructions.\n\n" +
    "<files_to_read>{PLAN, SUMMARY, impl files, VALIDATION.md}</files_to_read>" +
    "<gaps>{gap list}</gaps>" +
    "<test_infrastructure>{framework, config, commands}</test_infrastructure>" +
    "<constraints>Never modify impl files. Max 3 debug iterations. Escalate impl bugs.</constraints>",
  subagent_type="gsd-nyquist-auditor",
  model="{AUDITOR_MODEL}",
  description="Fill validation gaps for Phase {N}"
)

Handle return:

• ## GAPS FILLED → record tests + map updates, Step 6
• ## PARTIAL → record resolved, move escalated to manual-only, Step 6
• ## ESCALATE → move all to manual-only, Step 6

6. Generate/Update VALIDATION.md

State B (create):

1. Read template from ~/.claude/get-shit-done/templates/VALIDATION.md
2. Fill: frontmatter, Test Infrastructure, Per-Task Map, Manual-Only, Sign-Off
3. Write to ${PHASE_DIR}/${PADDED_PHASE}-VALIDATION.md

State A (update):

1. Update Per-Task Map statuses, add escalated to Manual-Only, update frontmatter
2. Append audit trail:

## Validation Audit {date}
| Metric | Count |
|--------|-------|
| Gaps found | {N} |
| Resolved | {M} |
| Escalated | {K} |

7. Commit

git add {test_files}
git commit -m "test(phase-${PHASE}): add Nyquist validation tests"

node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" commit "docs(phase-${PHASE}): add/update validation strategy"

8. Results + Routing

Compliant:

GSD > PHASE {N} IS NYQUIST-COMPLIANT
All requirements have automated verification.
▶ Next: /gsd:audit-milestone ${GSD_WS}

Partial:

GSD > PHASE {N} VALIDATED (PARTIAL)
{M} automated, {K} manual-only.
▶ Retry: /gsd:validate-phase {N} ${GSD_WS}
