msd-core/gsd-core/workflows/health.md

Validate `.planning/` directory integrity and report actionable issues. Checks for missing files, invalid configurations, inconsistent state, and orphaned plans. Optionally repairs auto-fixable issues.

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

**Parse arguments:**

Check if --repair, --backfill, or --context flags are present in the command arguments.

REPAIR_FLAG=""
BACKFILL_FLAG=""
CONTEXT_MODE=""
if arguments contain "--repair"; then
  REPAIR_FLAG="--repair"
fi
if arguments contain "--backfill"; then
  BACKFILL_FLAG="--backfill"
fi
if arguments contain "--context"; then
  CONTEXT_MODE="true"
fi

If CONTEXT_MODE is set, jump to the context_check step and skip the integrity validation steps. The two modes are orthogonal — context utilization has nothing to do with .planning/ directory health.

**Run only when `--context` is set.**

The model running this workflow self-reports the current session's approximate tokensUsed and the active model's contextWindow. Use the values visible in your runtime (Claude Code's /context slash command output, or the model's own session telemetry). If the runtime exposes neither, prompt the user once via AskUserQuestion for both numbers.

TEXT_MODE fallback: when text_mode is true (config or --text flag) the runtime is non-Claude (Codex, Gemini, etc.) and AskUserQuestion is not available — replace the prompt with a plain-text two-question sequence ("Approximate tokens used? Context window size?") and read the answers as plain text from the user's response.

_GSD_SHIM_NAME="gsd-tools.cjs"; _GSD_RUNTIME_ROOT="${RUNTIME_DIR:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}"; GSD_TOOLS="${_GSD_RUNTIME_ROOT}/gsd-core/bin/${_GSD_SHIM_NAME}"; if [ -f "$GSD_TOOLS" ]; then gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif command -v gsd-tools >/dev/null 2>&1; then GSD_TOOLS="$(command -v gsd-tools)"; gsd_run() { "$GSD_TOOLS" "$@"; }; elif [ -f "$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; else echo "ERROR: gsd-tools.cjs not found at $GSD_TOOLS and gsd-tools is not on PATH. Run: npx -y @opengsd/gsd-core@latest --claude --local" >&2; exit 1; fi
gsd_run query validate.context \
  --tokens-used "$TOKENS_USED" \
  --context-window "$CONTEXT_WINDOW"

The query prints a one-line status (Context utilization: NN% (state)) plus a recommendation line for the warning and critical states. Print the SDK output verbatim and end the workflow — do not mix in .planning/ health output, the two modes are independent diagnostics.

**Run health validation:**

gsd_run query validate.health $REPAIR_FLAG $BACKFILL_FLAG

Parse JSON output:

• status: "healthy" | "degraded" | "broken"
• errors[]: Critical issues (code, message, fix, repairable)
• warnings[]: Non-critical issues
• info[]: Informational notes
• repairable_count: Number of auto-fixable issues
• repairs_performed[]: Actions taken if --repair was used

**Format and display results:**

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 GSD Health Check
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Status: HEALTHY | DEGRADED | BROKEN
Errors: N | Warnings: N | Info: N

If repairs were performed:

## Repairs Performed

- ✓ config.json: Created with defaults
- ✓ STATE.md: Regenerated from roadmap

If errors exist:

## Errors

- [E001] config.json: JSON parse error at line 5
  Fix: Run /gsd:health --repair to reset to defaults

- [E002] PROJECT.md not found
  Fix: Run /gsd:new-project to create

If warnings exist:

## Warnings

- [W002] STATE.md references phase 5, but only phases 1-3 exist
  Fix: Review STATE.md manually before changing it; repair will not overwrite an existing STATE.md

- [W005] Phase directory "1-setup" doesn't follow NN-name format
  Fix: Rename to match pattern (e.g., 01-setup)

If info exists:

## Info

- [I001] 02-implementation/02-01-PLAN.md has no SUMMARY.md
  Note: May be in progress

Footer (if repairable issues exist and --repair was NOT used):

---
N issues can be auto-repaired. Run: /gsd:health --repair

**If repairable issues exist and --repair was NOT used:**

Ask user if they want to run repairs:

Would you like to run /gsd:health --repair to fix N issues automatically?

If yes, re-run with --repair flag and display results.

**If repairs were performed:**

Re-run health check without --repair to confirm issues are resolved:

gsd_run query validate.health

Report final status.

<repair_actions>

Action	Effect	Risk
createConfig	Create config.json with defaults	None
resetConfig	Delete + recreate config.json	Loses custom settings
regenerateState	Create STATE.md from ROADMAP structure when it is missing	Loses session history
addNyquistKey	Add workflow.nyquist_validation: true to config.json	None — matches existing default
backfillMilestones	Synthesize missing MILESTONES.md entries from .planning/milestones/vX.Y-ROADMAP.md snapshots	None — additive only; triggered by --backfill flag

Not repairable (too risky):

• PROJECT.md, ROADMAP.md content
• Phase directory renaming
• Orphaned plan cleanup

</repair_actions>

<stale_task_cleanup> Windows-specific: Check for stale Claude Code task directories that accumulate on crash/freeze. These are left behind when subagents are force-killed and consume disk space.

When --repair is active, detect and clean up:

# Check for stale task directories (older than 24 hours)
TASKS_DIR="$HOME/.claude/tasks"
if [ -d "$TASKS_DIR" ]; then
  STALE_COUNT=$( (find "$TASKS_DIR" -maxdepth 1 -type d -mtime +1 2>/dev/null || true) | wc -l )
  if [ "$STALE_COUNT" -gt 0 ]; then
    echo "⚠️  Found $STALE_COUNT stale task directories in ~/.claude/tasks/"
    echo "   These are leftover from crashed subagent sessions."
    echo "   Run: rm -rf ~/.claude/tasks/*  (safe — only affects dead sessions)"
  fi
fi

Report as info diagnostic: I002 | info | Stale subagent task directories found | Yes (--repair removes them) </stale_task_cleanup>
