msd-core/get-shit-done/workflows/code-review-fix.md

Auto-fix issues from REVIEW.md. Validates phase, checks config gate, verifies REVIEW.md exists and has fixable issues, spawns gsd-code-fixer agent, handles --auto iteration loop (capped at 3), commits REVIEW-FIX.md once at the end, and presents results.

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting. </required_reading>

<available_agent_types>

• gsd-code-fixer: Applies fixes to code review findings
• gsd-code-reviewer: Reviews source files for bugs and issues </available_agent_types>

Parse arguments and load project state:

PHASE_ARG="${1}"
INIT=$(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 from init JSON: phase_found, phase_dir, phase_number, phase_name, padded_phase, commit_docs.

Input sanitization (defense-in-depth):

# Validate PADDED_PHASE contains only digits and optional dot (e.g., "02", "03.1")
if ! [[ "$PADDED_PHASE" =~ ^[0-9]+(\.[0-9]+)?$ ]]; then
  echo "Error: Invalid phase number format: '${PADDED_PHASE}'. Expected digits (e.g., 02, 03.1)."
  # Exit workflow
fi

Phase validation (before config gate): If phase_found is false, report error and exit:

Error: Phase ${PHASE_ARG} not found. Run /gsd-status to see available phases.

This runs BEFORE config gate check so user errors are surfaced immediately regardless of config state.

Parse optional flags from $ARGUMENTS:

FIX_ALL=false
AUTO_MODE=false
for arg in "$@"; do
  if [[ "$arg" == "--all" ]]; then FIX_ALL=true; fi
  if [[ "$arg" == "--auto" ]]; then AUTO_MODE=true; fi
done

Compute scope variable:

if [ "$FIX_ALL" = "true" ]; then
  FIX_SCOPE="all"
else
  FIX_SCOPE="critical_warning"
fi

Compute review and fix report paths:

REVIEW_PATH="${PHASE_DIR}/${PADDED_PHASE}-REVIEW.md"
FIX_REPORT_PATH="${PHASE_DIR}/${PADDED_PHASE}-REVIEW-FIX.md"

Check if code review is enabled via config:

CODE_REVIEW_ENABLED=$(node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" config-get workflow.code_review 2>/dev/null || echo "true")

If CODE_REVIEW_ENABLED is "false":

Code review fix skipped (workflow.code_review=false in config)

Exit workflow.

Default is true — only skip on explicit false. This check runs AFTER phase validation so invalid phase errors are shown first.

Note: This reuses the workflow.code_review config key rather than introducing a separate workflow.code_review_fix key. Rationale: fixes are meaningless without review, so a single toggle makes sense. If independent control is needed later, a separate key can be added in v2.

Verify that REVIEW.md exists:

if [ ! -f "${REVIEW_PATH}" ]; then
  echo "Error: No REVIEW.md found for Phase ${PHASE_ARG}. Run /gsd-code-review ${PHASE_ARG} first."
  exit 1
fi

Do NOT auto-run code-review. Require explicit user action to ensure review intent is clear.

Parse REVIEW.md frontmatter to check status and extract context for --auto loop:

# Parse status field
REVIEW_STATUS=$(REVIEW_PATH="${REVIEW_PATH}" node -e "
  const fs = require('fs');
  const content = fs.readFileSync(process.env.REVIEW_PATH, 'utf-8');
  const match = content.match(/^---\n([\s\S]*?)\n---/);
  if (match && /status:\s*(\S+)/.test(match[1])) {
    console.log(match[1].match(/status:\s*(\S+)/)[1]);
  } else {
    console.log('unknown');
  }
" 2>/dev/null)

If status is "clean" or "skipped":

No issues to fix in Phase ${PHASE_ARG} REVIEW.md (status: ${REVIEW_STATUS}).

Exit workflow.

If status is "unknown":

Warning: Could not parse REVIEW.md status. Proceeding with fix attempt.

Extract review depth for --auto re-review:

REVIEW_DEPTH=$(REVIEW_PATH="${REVIEW_PATH}" node -e "
  const fs = require('fs');
  const content = fs.readFileSync(process.env.REVIEW_PATH, 'utf-8');
  const match = content.match(/^---\n([\s\S]*?)\n---/);
  if (match && /depth:\s*(\S+)/.test(match[1])) {
    console.log(match[1].match(/depth:\s*(\S+)/)[1]);
  } else {
    console.log('standard');
  }
" 2>/dev/null)

Extract original review file list for --auto re-review scope persistence:

# Extract review file list — portable bash 3.2+ (no mapfile, handles spaces in paths)
REVIEW_FILES_ARRAY=()
while IFS= read -r line; do
  [ -n "$line" ] && REVIEW_FILES_ARRAY+=("$line")
done < <(REVIEW_PATH="${REVIEW_PATH}" node -e "
  const fs = require('fs');
  const content = fs.readFileSync(process.env.REVIEW_PATH, 'utf-8');
  const match = content.match(/^---\n([\s\S]*?)\n---/);
  if (match) {
    const fm = match[1];
    // Try YAML array format: files_reviewed_list: [file1, file2]
    const bracketMatch = fm.match(/files_reviewed_list:\s*\[([^\]]+)\]/);
    if (bracketMatch) {
      bracketMatch[1].split(',').map(f => f.trim()).filter(Boolean).forEach(f => console.log(f));
    } else {
      // Try YAML list format: files_reviewed_list:\n  - file1\n  - file2
      let inList = false;
      for (const line of fm.split('\n')) {
        if (/files_reviewed_list:/.test(line)) { inList = true; continue; }
        if (inList && /^\s+-\s+(.+)/.test(line)) { console.log(line.match(/^\s+-\s+(.+)/)[1].trim()); }
        else if (inList && /^\S/.test(line)) { break; }
      }
    }
  }
" 2>/dev/null)

If REVIEW.md contains a files_reviewed_list frontmatter field, use that as the re-review scope. If not present, fall back to re-reviewing the full phase (same behavior as initial code-review).

Spawn the gsd-code-fixer agent with config:

# Build config for agent
echo "Applying fixes from ${REVIEW_PATH}..."
echo "Fix scope: ${FIX_SCOPE}"

Use Task() to spawn agent:

Task(subagent_type="gsd-code-fixer", prompt="
<files_to_read>
${REVIEW_PATH}
</files_to_read>

<config>
phase_dir: ${PHASE_DIR}
padded_phase: ${PADDED_PHASE}
review_path: ${REVIEW_PATH}
fix_scope: ${FIX_SCOPE}
fix_report_path: ${FIX_REPORT_PATH}
iteration: 1
</config>

Read REVIEW.md findings, apply fixes, commit each atomically, write REVIEW-FIX.md. Do NOT commit REVIEW-FIX.md (orchestrator handles that).
")

Agent failure handling:

If Task() fails:

Error: Code fix agent failed: ${error_message}

Check if FIX_REPORT_PATH exists:

• If yes: "Partial success — some fixes may have been committed."
• If no: "No fixes applied."

Either way:

Some fix commits may already exist in git history — check git log for fix(${PADDED_PHASE}) commits.
You can retry with /gsd-code-review-fix ${PHASE_ARG}.

Exit workflow (skip auto loop).

Key design decisions for --auto (addresses ALL review HIGH concerns):

1. Re-review scope: Uses REVIEW_FILES_ARRAY from original REVIEW.md frontmatter, falling back to full phase scope. Scope is NOT lost between iterations. Uses portable while-read loop (bash 3.2+ compatible, handles spaces in paths).
2. Artifact semantics: REVIEW.md is overwritten by each re-review (latest review state). REVIEW-FIX.md is overwritten by each fixer iteration (latest fix state with iteration count). There is ONE final version of each artifact, not per-iteration copies. Backup files (.iterN.md) preserve history for post-mortem analysis if iterations degrade.
3. Commit timing: Fix commits happen per-finding inside the agent. REVIEW-FIX.md is NOT committed until step 7 (after ALL iterations complete). Only ONE docs commit for REVIEW-FIX.md, not one per iteration.

After ALL iterations complete (or single pass in non-auto mode), validate and commit REVIEW-FIX.md:

if [ -f "${FIX_REPORT_PATH}" ]; then
  # Validate REVIEW-FIX.md has valid YAML frontmatter with status field
  HAS_STATUS=$(REVIEW_PATH="${REVIEW_PATH}" node -e "
    const fs = require('fs');
    const content = fs.readFileSync(process.env.FIX_REPORT_PATH, 'utf-8');
    const match = content.match(/^---\n([\s\S]*?)\n---/);
    if (match && /status:/.test(match[1])) { console.log('valid'); } else { console.log('invalid'); }
  " 2>/dev/null)
  
  if [ "$HAS_STATUS" = "valid" ]; then
    echo "REVIEW-FIX.md created at ${FIX_REPORT_PATH}"
    
    if [ "$COMMIT_DOCS" = "true" ]; then
      node "$HOME/.claude/get-shit-done/bin/gsd-tools.cjs" commit \
        "docs(${PADDED_PHASE}): add code review fix report" \
        --files "${FIX_REPORT_PATH}"
    fi
  else
    echo "Warning: REVIEW-FIX.md has invalid frontmatter (no status field). Not committing."
    echo "Agent may have produced malformed output. Review manually: ${FIX_REPORT_PATH}"
  fi
else
  echo "Warning: REVIEW-FIX.md not found at ${FIX_REPORT_PATH}."
  echo "Agent may have failed before writing report."
  echo "Check git log for any fix(${PADDED_PHASE}) commits that were applied."
fi

This commit happens ONCE at the end of the workflow, after all iterations (if --auto) complete. Not per-iteration.

Parse REVIEW-FIX.md frontmatter and present formatted summary to user.

First check if fix report exists:

if [ ! -f "${FIX_REPORT_PATH}" ]; then
  echo ""
  echo "═══════════════════════════════════════════════════════════════"
  echo ""
  echo "  ⚠ No fix report generated"
  echo ""
  echo "───────────────────────────────────────────────────────────────"
  echo ""
  echo "The fixer agent may have failed before completing."
  echo "Check git log for any fix(${PADDED_PHASE}) commits."
  echo ""
  echo "Retry: /gsd-code-review-fix ${PHASE_ARG}"
  echo ""
  echo "═══════════════════════════════════════════════════════════════"
  exit 1
fi

Extract frontmatter fields:

# Extract only the YAML frontmatter block (between first two --- lines)
FIX_FRONTMATTER=$(REVIEW_PATH="${REVIEW_PATH}" node -e "
  const fs = require('fs');
  const content = fs.readFileSync(process.env.FIX_REPORT_PATH, 'utf-8');
  const match = content.match(/^---\n([\s\S]*?)\n---/);
  if (match) process.stdout.write(match[1]);
" 2>/dev/null)

# Parse fields from frontmatter only (not full file)
FIX_STATUS=$(echo "$FIX_FRONTMATTER" | grep "^status:" | cut -d: -f2 | xargs)
FINDINGS_IN_SCOPE=$(echo "$FIX_FRONTMATTER" | grep "^findings_in_scope:" | cut -d: -f2 | xargs)
