project-health（项目健康）

Project Health

One skill for everything about your project's Claude Code configuration. Run it at the start, middle, or end of a project — it figures out what's needed.

Goal: Zero permission prompts, well-organised context files, no cruft.

When to Use

Architecture: Sub-Agents

Heavy analysis runs in sub-agents to keep the main conversation clean. The main agent orchestrates; sub-agents do the scanning and return summaries.

Agent 1: Permission Auditor

Launched with Task(subagent_type: "general-purpose"). Prompt:

Read .claude/settings.local.json.

**Discover connected MCP servers**: Use ToolSearch (search "mcp") and extract unique
server prefixes from tool names (e.g. mcp__vault__secret_list → vault).

**Discover installed skills**: Use the Skill tool or ToolSearch to list available skills.
For each skill that has scripts/ in its directory, note what Bash patterns it needs
(python3, env var prefixes like GEMINI_API_KEY=*, etc.). Check the SKILL.md for any
MCP tools the skill references (e.g. mcp__vault__secret_get).

Report:
1. MCP servers connected but NOT in settings (missing)
2. MCP servers in settings but NOT connected (stale)
3. Skill permissions: Bash patterns and MCP tools that installed skills need but aren't approved
4. File access: check for Read/Edit/Write patterns for .claude/** and //tmp/**
   in project settings, and ~/Documents/**/~/.claude/** in global settings
5. Leaked secrets: entries containing API keys, tokens, bearer strings, hex >20 chars, base64 >20 chars
6. Legacy colon syntax: entries like Bash(git:*) instead of Bash(git *)
7. Junk entries: shell fragments (Bash(do), Bash(fi), Bash(then), Bash(else), Bash(done)),
   __NEW_LINE_* artefacts, loop body fragments (Bash(break), Bash(continue), Bash(echo *))
8. Duplicates: entries covered by a broader pattern (e.g. Bash(git add *) redundant if Bash(git *) exists)
9. Missing presets: based on files present, suggest presets from [permission-presets.md]

Prefer Read/Glob/Grep tools over Bash. If you need to scan multiple files or
run 3+ commands for one analysis, write a Python script to .jez/scripts/
and run it once (mkdir -p .jez/scripts first).

Return a structured summary, not raw data.

Agent 2: Context Auditor

Launched with Task(subagent_type: "general-purpose"). Prompt:

Audit the project context landscape at [repo-path]:

1. Find all CLAUDE.md files. For each:
   - Count lines (target: root 50-150, subdirs 15-50)
   - Score quality on 6 criteria (see quality-criteria.md)
   - Check for stale file/path references
   - Flag oversized files

2. Find .claude/rules/ topic files. Check sizes (target: 20-80 lines).

3. Detect project type from files present (see project-types.md).
   Check expected docs exist (ARCHITECTURE.md, DATABASE_SCHEMA.md, etc.)

4. Find public markdown (README.md, LICENSE, CONTRIBUTING.md).
   Check for overlap with CLAUDE.md content.

5. Check auto-memory at ~/.claude/projects/*/memory/MEMORY.md

6. If Cloudflare project: find all wrangler.jsonc/wrangler.toml files.
   Check each has "observability": { "enabled": true }. Flag any missing it.

Prefer Read/Glob/Grep tools over Bash. If you need to scan many files or
aggregate data across the repo, write a Python script to .jez/scripts/
and run it once rather than running many individual bash commands
(mkdir -p .jez/scripts first).

Return: project type, quality scores, missing docs, stale refs, overlaps,
size violations, observability gaps, and total markdown footprint.

Parallel Execution

For a full health check, launch both agents in parallel:

Task(subagent_type: "general-purpose", name: "permission-audit", prompt: "...")
Task(subagent_type: "general-purpose", name: "context-audit", prompt: "...")

Both return summaries. The main agent combines them into one report and proposes fixes.

Mode 1: Full Health Check

The default. Run this anytime.

Steps

1. Launch Permission Auditor and Context Auditor agents in parallel
2. Combine findings into a single report: ## Project Health Report **Project type**: [detected type] **CLAUDE.md quality**: [score]/100 ([grade]) ### Permissions - Missing MCP servers: [list] - Leaked secrets: [count] found - Legacy syntax: [count] entries - Missing presets: [list] ### Context - Oversized files: [list] - Stale references: [list] - Missing docs: [list] - Overlaps: [list] ### Recommended Fixes 1. [fix 1] 2. [fix 2]...
3. Apply fixes after single yes/no confirmation

Mode 2: New Project Setup

When: No .claude/settings.local.json exists, or user says "setup" / "kickoff".

Steps

1. Detect project type from files present: Indicator Type Preset wrangler.jsonc or wrangler.toml cloudflare-worker JS/TS + Cloudflare vercel.json or next.config.* vercel-app JS/TS + Vercel astro.config.* astro JS/TS + Static Sites package.json (no deploy target) javascript-typescript JS/TS pyproject.toml or setup.py or requirements.txt python Python Cargo.toml rust Rust go.mod go Go Gemfile or Rakefile ruby Ruby composer.json or wp-config.php php PHP pom.xml or build.gradle* java Java/JVM *.sln or *.csproj dotnet.NET mix.exs elixir Elixir Package.swift swift Swift + macOS pubspec.yaml flutter Mobile Dockerfile or docker-compose.yml docker Docker fly.toml or railway.json or netlify.toml hosted-app Hosting Platforms supabase/config.toml supabase Hosting + Database .claude/agents/ or operational scripts ops-admin — Empty directory Ask the user — Types stack (e.g. cloudflare-worker + javascript-typescript).
2. Generate .claude/settings.local.json:

- Read references/permission-presets.md - Always include Universal Base (includes file access for .claude/**, //tmp/**) - Add detected language + deployment presets - Check if global ~/.claude/settings.local.json has home-relative file access patterns (~/Documents/**, ~/.claude/**). If not, suggest adding them there (NOT in the project file — home paths belong in global settings only) - Launch Permission Auditor agent to discover MCP servers and add per-server wildcards - Always include WebSearch, WebFetch - Always include explicit gh subcommands (workaround for Bash(gh *) bug) - Write with // comment groups

1. Generate CLAUDE.md:

- Read references/templates.md - Use project-type-appropriate template

1. Generate .gitignore:

- Read references/templates.md - Always include .claude/settings.local.json, .claude/plans/, .jez/screenshots/, .jez/artifacts/ - Do NOT gitignore .jez/scripts/ — generated scripts are worth keeping

1. Optionally (ask first): git init + gh repo create
2. Warn: "Project settings.local.json SHADOWS global settings (does not merge). Session restart needed."

Mode 3: Tidy Permissions

When: User says "tidy permissions" or health check found permission issues.

Launch the Permission Auditor agent, then apply its recommended fixes.

Mode 4: Capture Learnings

When: End of session, "capture learnings", "save what we learned".

This runs in the main context (not a sub-agent) because it needs access to the conversation history.

1. Review conversation for discoveries worth preserving
2. Decide placement: Applies to all projects? ├── YES → ~/.claude/rules/<topic>.md └── NO → Specific to a subdirectory? ├── YES → <dir>/CLAUDE.md └── NO → Reference or operational? ├── Reference → docs/ or ARCHITECTURE.md └── Operational →./CLAUDE.md (root)
3. Draft all changes as diffs in a single batch
4. Apply after single yes/no confirmation

Keep it concise: one line per concept.

Mode 5: Add Preset

When: "add python permissions", "add docker", "add MCP servers".

1. Read the preset from references/permission-presets.md
2. Read existing .claude/settings.local.json
3. Merge without duplicating
4. Remind: session restart required

Mode 6: Restructure Context

When: Root CLAUDE.md over 200 lines, "restructure memory".

1. Launch Context Auditor agent first
2. Based on findings:

- Split oversized CLAUDE.md into .claude/rules/<topic>.md - Extract directory-specific content to sub-directory CLAUDE.md - Move reference material to docs/ - Resolve overlaps - Create missing docs for project type

1. Present plan, apply after approval

What Does NOT Work

Important Behaviours

• Not hot-reloaded: settings.local.json edits need session restart
• "Don't ask again" injects at runtime (no restart) using colon format — normal
• Shadows, not merges: Project settings completely replace global
• gh bug: Bash(gh *) sometimes misses subcommands — include explicit Bash(gh issue *) etc.

Autonomy

• Just do it: Detect project type, launch audit agents, discover MCP servers
• Brief confirmation: Write/update files (single batch yes/no)
• Ask first: git init, GitHub repo, delete existing content, major restructures
