  Hygiene (C1-C7)  Sync (S1-S3)

Hygiene Module — Checks (7 items)

Check 1: Junk Files

find .claude/ -name ".DS_Store" -o -name "*.zip" -o -name ".tmp*" 2>/dev/null

• Has results → P1: List files, suggest deletion
• No results → ✅

Check 2-3: .gitignore

ls .claude/.gitignore 2>/dev/null || echo "MISSING"

Missing → P1. If exists, read content and compare required items:

Missing any → P2

Check 4: Naming Consistency

# Scan all skill subdirectories
for dir in .claude/skills/*/; do
  if [ -d "${dir}reference" ]; then echo "INCONSISTENT: ${dir}reference"; fi
done

Has reference/ (singular) → P2, suggest renaming to references/

Check 5: README Count Sync

# Count actual items
ls .claude/commands/ 2>/dev/null | wc -l
ls .claude/skills/ 2>/dev/null | wc -l
ls .claude/agents/ 2>/dev/null | wc -l
ls .claude/rules/ 2>/dev/null | wc -l
ls .claude/hooks/*.sh 2>/dev/null | wc -l

Extract counts from README.md, compare. Mismatch → P2

Check 6: Command-Skill Pairing

Scan all skills/*/SKILL.md, exclude these types, then check for corresponding command:

Remaining skills without command → P1

Check 7: Cache Size

du -sh .claude/cache/ 2>/dev/null

• > 50M → P2, suggest cleanup
• ≤ 50M → ✅

Sync Module — Checks (S1-S3)

Only runs when --scope sync or --scope all (default).

S1: Version Check

Plugin version resolution (priority order):

.claude-plugin/plugin.json → package.json → "unknown"

Plugin source location (same as /install-rules Phase 1):

Glob: ~/.claude/plugins/**/sd0x-dev-flow/rules/auto-loop.md
Glob: ${REPO_ROOT}/node_modules/sd0x-dev-flow/rules/auto-loop.md
Fallback: @rules/auto-loop.md (plugin-relative)

S2: Component Classification

For each managed component (rules, hooks, scripts), compute 3 hashes and classify:

manifest_hash  = manifest[category][filename].hash    # null if missing
local_hash     = git hash-object --no-filters <local-path>  # null if file missing
plugin_hash    = git hash-object --no-filters <plugin-path>  # source of truth

Classification table (read-only diagnostic; maps to install-rules states for delegation):

Managed inventory (hardcoded):

S2.5: Override Safeguard Checks

5 checks for project override files (e.g., auto-loop-project.md):

Policy contradiction detection: Parse the project override's Auto-Trigger table for required check commands. Cross-reference against hook-enforced sentinels: if override omits /codex-review-fast for code changes or /codex-review-doc for .md changes, flag as P1.

Override drift detection: Read the <!-- Based on: auto-loop.md @ <hash> --> comment from the project file. Compare against git hash-object --no-filters .claude/rules/auto-loop.md | cut -c1-7. If different, the base has been updated since the override was authored. Uses blob hash for content-level comparison; accepts legacy commit-style hashes (any 7+ hex chars) during backward-compat transition.

S3: Settings Compatibility

Check both settings.json and settings.local.json (precedence: settings.local.json > settings.json). A hook entry in either file satisfies the integrity check.

Settings file precedence: settings.local.json overrides settings.json at runtime. When delegating S3 fixes, use /install-hooks --local if the issue is in settings.local.json.

Legacy path detection:

Grep for: "\.claude/hooks/[^"]+\.sh"  (without leading "$CLAUDE_PROJECT_DIR")
Applied to both: settings.json and settings.local.json

Fix Tiers

Only applies when --fix-safe or --fix is specified alongside sync scope.

Category-specific safe fix delegation:

Why hooks/scripts OUTDATED is report-only in safe tier: /install-hooks and /install-scripts use skip/force semantics (no manifest-aware smart merge). Only /install-rules has 7-state classification for safe auto-update.

S3 settings fix delegation: All settings mutations delegate to /install-hooks (sync module never writes JSON directly).

--fix tier: Delegates all actionable states (including CONFLICT, LEGACY) to /install-* commands which handle interactive resolution.

Argument conflict: --fix and --fix-safe are mutually exclusive. If both specified, error.

Verification

• Hygiene: All 7 checks executed (when scope includes hygiene)
• Sync: S1-S3 checks executed (when scope includes sync)
• Each check has clear ✅/⛔ status
• P1 issues have specific fix commands
• S2 classification covers all 23 managed files
• Fix delegation uses targeted file names (not --all)

Examples

Input: /claude-health
Action: Scan hygiene (7 items) + sync (S1-S3) → Generate consolidated report

Input: /claude-health --scope sync
Action: Scan S1-S3 only → Report version drift + component status

Input: /claude-health --fix-safe
Action: Scan all → Auto-fix safe items → Delegate to /install-* → Report
