# Claude Settings Audit

Analyze this repository and generate recommended Claude Code `settings.json` permissions for read-only commands.

## Phase 1: Detect Tech Stack

Run these commands to detect the repository structure:

```bash
ls -la
find . -maxdepth 2 \( -name "*.toml" -o -name "*.json" -o -name "*.lock" -o -name "*.yaml" -o -name "*.yml" -o -name "Makefile" -o -name "Dockerfile" -o -name "*.tf" \) 2>/dev/null | head -50
```

Check for these indicator files:

| Category | Files to Check |
|----------|---------------|
| **Python** | `pyproject.toml`, `setup.py`, `requirements.txt`, `Pipfile`, `poetry.lock`, `uv.lock` |
| **Node.js** | `package.json`, `package-lock.json`, `yarn.lock`, `pnpm-lock.yaml` |
| **Go** | `go.mod`, `go.sum` |
| **Rust** | `Cargo.toml`, `Cargo.lock` |
| **Ruby** | `Gemfile`, `Gemfile.lock` |
| **Java** | `pom.xml`, `build.gradle`, `build.gradle.kts` |
| **Build** | `Makefile`, `Dockerfile`, `docker-compose.yml` |
| **Infra** | `*.tf` files, `kubernetes/`, `helm/` |
| **Monorepo** | `lerna.json`, `nx.json`, `turbo.json`, `pnpm-workspace.yaml` |

## Phase 2: Detect Services

Check for service integrations:

| Service | Detection |
|---------|-----------|
| **Sentry** | `sentry-sdk` in deps, `@sentry/*` packages, `.sentryclirc`, `sentry.properties` |
| **Linear** | Linear config files, `.linear/` directory |

Read dependency files to identify frameworks:
- `package.json` → check `dependencies` and `devDependencies`
- `pyproject.toml` → check `[project.dependencies]` or `[tool.poetry.dependencies]`
- `Gemfile` → check gem names
- `Cargo.toml` → check `[dependencies]`

## Phase 3: Check Existing Settings

```bash
cat .claude/settings.json 2>/dev/null || echo "No existing settings"
```

## Phase 4: Generate Recommendations

Build the allow list by combining:

#### Other Languages

| If Detected | Add These Commands |
|-------------|-------------------|
| `go.mod` | `go version`, `go list`, `go mod graph`, `go env` |
| `Cargo.toml` | `rustc --version`, `cargo --version`, `cargo tree`, `cargo metadata` |
| `Gemfile` | `ruby --version`, `bundle list`, `bundle show` |
| `pom.xml` | `java --version`, `mvn --version`, `mvn dependency:tree` |

| `Makefile` | `make --version`, `make -n` |

### Skills (for Sentry Projects)

If this is a Sentry project (or sentry-skills plugin is installed), include:

```json
[
  "Skill(sentry-skills:commit)",
  "Skill(sentry-skills:create-pr)",
  "Skill(sentry-skills:code-review)",
  "Skill(sentry-skills:find-bugs)",
  "Skill(sentry-skills:iterate-pr)",
  "Skill(sentry-skills:claude-settings-audit)",
  "Skill(sentry-skills:agents-md)"
]
```

### WebFetch Domains

#### Always Include (Sentry Projects)
```json
[
  "WebFetch(domain:docs.sentry.io)",
  "WebFetch(domain:develop.sentry.dev)",
  "WebFetch(domain:docs.github.com)",
  "WebFetch(domain:cli.github.com)"
]
```

#### Framework-Specific

| If Detected | Add Domains |
|-------------|-------------|
| **Django** | `docs.djangoproject.com` |
| **Flask** | `flask.palletsprojects.com` |
| **FastAPI** | `fastapi.tiangolo.com` |
| **React** | `react.dev` |
| **Next.js** | `nextjs.org` |

### MCP Server Suggestions

MCP servers are configured in `.mcp.json` (not `settings.json`). Check for existing config:

```bash
cat .mcp.json 2>/dev/null || echo "No existing .mcp.json"
```

#### Sentry MCP (if Sentry SDK detected)

Add to `.mcp.json` (replace `{org-slug}` and `{project-slug}` with your Sentry organization and project slugs):
```json
{
  "mcpServers": {
    "sentry": {
      "type": "http",
      "url": "https://mcp.sentry.dev/mcp/{org-slug}/{project-slug}"
    }
  }
}
```

#### Linear MCP (if Linear usage detected)

Add to `.mcp.json`:
```json
{
  "mcpServers": {
    "linear": {
      "command": "npx",
      "args": ["-y", "@linear/mcp-server"],
      "env": {
        "LINEAR_API_KEY": "${LINEAR_API_KEY}"
      }
    }
  }
}
```

**Note**: Never suggest GitHub MCP. Always use `gh` CLI commands for GitHub.

```

## Important Rules

### What to Include
- Only READ-ONLY commands that cannot modify state
- Only tools that are actually used by the project (detected via lock files)
- Standard system commands (ls, cat, find, etc.)
- The `:*` suffix allows any arguments to the base command

### What to NEVER Include
- **Absolute paths** - Never include user-specific paths like `/home/user/scripts/foo` or `/Users/name/bin/bar`
- **Custom scripts** - Never include project scripts that may have side effects (e.g., `./scripts/deploy.sh`)
- **Alternative package managers** - If the project uses pnpm, do NOT include npm/yarn commands
- **Commands that modify state** - No install, build, run, write, or delete commands

### Package Manager Rules

Only include the package manager actually used by the project:

| If Detected | Include | Do NOT Include |
|-------------|---------|----------------|
| `pnpm-lock.yaml` | pnpm commands | npm, yarn |
| `yarn.lock` | yarn commands | npm, pnpm |
| `package-lock.json` | npm commands | yarn, pnpm |
| `poetry.lock` | poetry commands | pip (unless also has requirements.txt) |
| `uv.lock` | uv commands | pip, poetry |
| `Pipfile.lock` | pipenv commands | pip, poetry |

If multiple lock files exist, include only the commands for each detected manager.
