Permissions Audit
Review and reorganize Claude Code permission settings so global settings are the source of truth, project-local files stay minimal, and read vs write operations have clear separation.
When to Use
- Reviewing what tools and commands are pre-allowed
- Cleaning up accumulated ad-hoc permission entries
- After adding a new MCP server and deciding which operations to pre-allow
- Ensuring global vs project-local settings are properly split
- Periodic hygiene check on permission sprawl
Phase 1: Discover All Settings Files
Scan for every settings file that contributes to the effective permission set.
Locations to check:
~/.claude/settings.json— global settings (source of truth)<project>/.claude/settings.json— project shared settings (committed)<project>/.claude/settings.local.json— project local settings (gitignored)~/.claude/.claude/settings.local.json— home directory project local- Any dotfiles-managed copy (e.g.
home/.claude/settings.jsonin a dotfiles repo)
Read all of them in parallel. If a file doesn't exist, note it and move on.
Phase 2: Audit
For each permission entry across all files, assess:
- Redundancy — Is this entry already covered by a broader rule elsewhere?
- Example:
Bash(gws calendar events:*)is redundant whenBash(gws:*)exists globally
- Example:
- Misplacement — Is this general-purpose but stuck in a project-local file?
- Example:
Bash(python3:*)in project local when it's useful everywhere
- Example:
- Inconsistent granularity — Are similar tools allowed at different specificity levels?
- Example: Global has
gh pr list,gh pr viewindividually, but project local hasgh:*
- Example: Global has
- Missing read/write distinction — Are read-only and write operations mixed together?
- Stale entries — One-time approvals that accumulated (e.g., a specific git command with hardcoded paths)
Present findings as a table with issues and proposed resolution for each.
Phase 3: Propose Reorganization
Design the new layout following these principles:
Global settings (source of truth)
Organize permissions into labeled sections by grouping related entries together. Do NOT use JSON comments (// or /* */) — settings.json must be valid JSON. Instead, rely on the ordering of entries to convey grouping. Within the allow array, cluster related permissions together in this order:
Section order (group entries in this sequence, no separators needed):
filesystem reads — cat, tree, grep, wc, file reads
<lang> inspection — go doc, cargo check, linters (no side effects)
GitHub CLI reads — gh pr list/view/diff, gh issue list (no mutations)
external tool reads — calendar, slack CLI, other read CLIs
web reads — WebSearch, WebFetch with domain allowlist
MCP <service> reads — list, get, describe, search operations
build / test / install — go build, cargo test, pnpm install (local side effects)
skills — Skill(superpowers:*), etc.
Project-local settings (minimal overrides)
Only keep entries that are genuinely project-specific:
- Broader tool access needed for a specific workflow (e.g.,
Bash(gh:*)for a repo that creates PRs frequently) - Project-specific MCP tools not used elsewhere
- Temporary elevated access during active development
Clarifying questions
Before applying, ask the user about edge cases. Common questions:
- Scope of CLI tools: Should
gh:*(all subcommands) go global, or keep read-only globally with broader access per-project? - MCP write operations: Which write operations (send message, create issue) should stay prompted vs pre-allowed?
- Environment separation: Should dev and prod data sources have the same read access, or should prod be more restrictive?
- Dotfiles sync: Does the user maintain a dotfiles copy that needs updating?
Adapt questions to what's actually ambiguous — don't ask about things that are obvious from context.
Phase 4: Apply Changes
Once the user confirms the plan:
- Write the updated global settings file
- Write the trimmed project-local settings file
- Update any dotfiles copies to stay in sync
- Clear out entries from other local files that were absorbed into global
Phase 5: Summary
Present a before/after comparison:
| File | Before | After |
|---|---|---|
| Global | N flat entries | M entries in K sections |
| Project local | X entries | Y entries (project-specific only) |
List what moved where, and what still requires prompting (write operations not pre-allowed).
