Health: Audit the Six-Layer Stack
Prefix your first line with 🥷 inline, not as its own paragraph.
Audit the current project's Gemini CLI setup against the six-layer framework:
GEMINI.md → rules → skills → hooks → subagents → verifiers
Find violations. Identify the misaligned layer. Calibrate to project complexity only.
Output language: Check in order: (1) GEMINI.md ## Communication rule (global over local); (2) user's recent language; (3) English.
Step 0: Assess project tier
Pick one. Apply only that tier's requirements.
| Tier | Signal | What's expected |
|---|---|---|
| Simple | <500 files, 1 contributor, no CI | GEMINI.md only; 0-1 skills; hooks optional |
| Standard | 500-5K files, small team or CI | GEMINI.md + 1-2 rules; 2-4 skills; basic hooks |
| Complex | >5K files, multi-contributor, active CI | Full six-layer setup required |
Step 1: Collect data
Run the collection script. Do not interpret yet.
bash "${GEMINI_SKILL_DIR:-$HOME/.agents/skills/health}/scripts/collect-data.sh"
Sections may show (unavailable) when tools are missing:
jqmissing → conversation sections unavailablepython3missing → MCP/hooks/allowedTools sections unavailablesettings.local.jsonabsent → hooks/MCP may be unavailable (normal for global-only setups)
Treat (unavailable) as insufficient data, not a finding. Do not flag those areas.
Step 1b: MCP Live Check
Test every MCP server: call one harmless tool per server. Record live=yes/no with error detail. Respect enabled: false (skip without flagging). For API keys, only check if the env var is set (echo $VAR | head -c 5), never print full keys.
Step 2: Analyze
Confirm the tier. Then route:
- Simple: Analyze locally. No subagents.
- Standard/Complex: Launch two subagents in parallel. Redact credentials to
[REDACTED].- Agent 1 (Context + Security): Read
agents/inspector-context.md. FeedCONVERSATION SIGNALSsection. - Agent 2 (Control + Behavior): Read
agents/inspector-control.md. Feed detected tier.
- Agent 1 (Context + Security): Read
- Fallback: If a subagent fails, analyze that layer locally and note "(analyzed locally)".
Step 3: Report
Health Report: {project} ({tier} tier, {file_count} files)
[PASS] Passing checks (table, max 5 rows)
Finding format
- [severity] <symptom> ({file}:{line} if known)
Why: <one-line reason>
Action: <exact command or edit to fix>
Action: must be copy-pasteable. Never write "investigate X" or "consider Y". If the fix is unknown, name the diagnostic command.
[!] Critical -- fix now
Rules violated, dangerous allowedTools, MCP overhead >12.5%, security findings, leaked credentials.
Example:
- [!]
settings.local.jsoncommitted to git (exposes MCP tokens) Why: leaked token enables remote code execution via installed MCP servers Action:git rm --cached .gemini/settings.local.json && echo '.gemini/settings.local.json' >> .gitignore
[~] Structural -- fix soon
GEMINI.md content in wrong layer, missing hooks, oversized descriptions, verifier gaps.
[-] Incremental -- nice to have
Outdated items, global vs local placement, context hygiene, stale allowedTools entries.
If no issues: All relevant checks passed. Nothing to fix.
Non-goals
- Never auto-apply fixes without confirmation.
- Never apply complex-tier checks to simple projects.
Gotchas
| What happened | Rule |
|---|---|
| Missed the local override | Always read settings.local.json too; it shadows the committed file |
| Subagent timeout reported as MCP failure | MCP failures come from the live probe, not data collection |
| Reported issues in wrong language | Honor GEMINI.md Communication rule first |
| Flagged intentionally noisy hook as broken | Ask before calling a hook "broken" |
| Hook seemed not to fire, but it did -- a later UI element rendered above it | Hook firing order is not visual order. Before re-editing the hook config: (a) confirm with --debug or by piping output, (b) check whether a diff dialog, permission prompt, or other UI element rendered on top and pushed the hook output offscreen, (c) only then suspect the hook itself. |
Design System Audit
Activate when: "font not loading", "style inconsistency", "design tokens", or visual rendering bugs
Check:
- Font stack: @font-face paths, file existence, CORS headers
- Token drift: Hardcoded values that should reference design tokens
- Fallback chain: Fonts exist on target platform
- CSS variables: Inline styles bypassing the design system
Report findings with Action: lines, then ask before applying any fix.
