Agent skill

configuring-permissions

Use when adding allow/deny rules to Claude Code, granting project permissions, troubleshooting "permission denied" errors, "skill requires approval" prompts, or setting up shared team permissions. Also use when working with git worktrees and permissions aren't being inherited.

Configuring Permissions

STOP: Freshness Check Required

Before using this skill: Check .state file — if missing or last_evaluated > 7 days ago, warn user and research current CC issues before proceeding.

bash
find ~/.claude/plugins -path "*/claude-code/skills/configuring-permissions/.state" 2>/dev/null | head -1

Full procedure: freshness-check.md


Overview

Claude Code permissions control which tools/skills can run without prompting. Core principle: prompt grants update memory immediately; manual edits require restart.

CRITICAL

Team vs Solo Project Detection

Before modifying project settings: Check if changes affect a team (git shortlog -sne --all | head -10). User-level Skill(*) won't help teammates — team projects need project-level config.

Full decision flow: team-detection.md

Restart Requirement

Method Restart? Why
Prompt grant No Updates file AND in-memory simultaneously
Manual settings.json edit Yes File only read at startup

When manually editing settings.json, tell user:

Restart Claude Code for the new permission to take effect.

Skill Permission Naming

Common mistake: Using marketplace name instead of plugin name.

Plugin Identifier Correct Pattern Wrong Pattern
claude-code@jasonkuhrt Skill(claude-code:*) Skill(jasonkuhrt:*)
hookify@claude-plugins-official Skill(hookify:*) Skill(claude-plugins-official:*)

The format is Skill(plugin-name:skill-name), NOT Skill(marketplace-name:skill-name).

To find the correct plugin name: Look at the part BEFORE the @ in the plugin identifier.

MCP Permission Syntax

MCP permissions support three patterns (docs):

Pattern Matches
mcp__server All tools from server
mcp__server__* All tools (wildcard, equivalent)
mcp__server__tool Specific tool only

Example:

json
{
  "permissions": {
    "allow": [
      "mcp__serena",
      "mcp__claude-in-chrome",
      "mcp__effect-docs"
    ]
  }
}

Fully qualified names (e.g., mcp__serena__find_symbol) only needed to allow specific tools while denying others from the same server.

Note: Issue #3107 (July 2025) claimed wildcards weren't supported, but current docs confirm both patterns are valid and equivalent.

Skill Permissions

Skill(*) is broken everywhere:

  • ~/.claude/settings.json (user): buggy, sometimes ignored (#5140, #10833)
  • .claude/settings.json (project): doesn't work at all
  • .claude/settings.local.json (project local): works, but see team workaround below

For individuals: Use explicit patterns in user settings:

json
"Skill(plugin-name:*)"

Extract plugin names from enabledPlugins keys (the part before @).

For teams — Option A (simple, no personal overrides): Commit .claude/settings.local.json with skill permissions. Tradeoff: team members can't have personal overrides without merge conflicts.

For teams — Option B (recommended, allows personal overrides): Use a SessionStart hook to sync baseline permissions:

  1. Create .claude/settings.local.json.example (committed) with baseline permissions
  2. Keep .claude/settings.local.json gitignored
  3. Add SessionStart hook to sync example → local:
bash
#!/bin/bash
# .claude/scripts/sync-local-permissions.sh
EXAMPLE=".claude/settings.local.json.example"
LOCAL=".claude/settings.local.json"

[[ ! -f "$EXAMPLE" ]] && exit 0

if [[ ! -f "$LOCAL" ]]; then
  cp "$EXAMPLE" "$LOCAL"
  echo "Created $LOCAL from example. Restart CC for permissions to take effect."
  exit 0
fi

CURRENT=$(jq -S '.permissions.allow // [] | sort' "$LOCAL" 2>/dev/null || echo '[]')
BASELINE=$(jq -S '.permissions.allow // [] | sort' "$EXAMPLE" 2>/dev/null || echo '[]')
MERGED=$(jq -n --argjson a "$CURRENT" --argjson b "$BASELINE" '$a + $b | unique | sort')

if [[ "$CURRENT" != "$MERGED" ]]; then
  jq --argjson allow "$MERGED" '.permissions.allow = $allow' "$LOCAL" > "$LOCAL.tmp" && mv "$LOCAL.tmp" "$LOCAL"
  echo "Added baseline permissions. Restart CC for changes to take effect."
fi

Hook in .claude/settings.json:

json
{
  "hooks": {
    "SessionStart": [{ "hooks": [{ "type": "command", "command": ".claude/scripts/sync-local-permissions.sh" }] }]
  }
}

Benefits: team gets baseline permissions, individuals can add extras without conflicts.

Tracking: #10833 — when fixed, move to settings.json and simplify.

Permission Files

File Scope Committed? Precedence
~/.claude/settings.json User (global) No Lowest
.claude/settings.json Project Yes Middle
.claude/settings.local.json Project local Usually no Highest

Adding Permissions

Via Prompt (Recommended)

Select "Yes, and don't ask again" → adds to appropriate settings file, no restart needed.

Via Manual Edit

json
{
  "permissions": {
    "allow": ["Bash", "Skill(superpowers:*)"],
    "deny": []
  }
}

Team-Shared Permissions

dot
digraph team_permissions {
    "Project permission needed" [shape=box];
    "settings.local.json committed?" [shape=diamond];
    "Works for user only" [shape=box];
    "Share with team?" [shape=diamond];
    "Add to settings.local.json" [shape=box];
    "Override gitignore + commit" [shape=box];

    "Project permission needed" -> "settings.local.json committed?";
    "settings.local.json committed?" -> "Add to settings.local.json" [label="yes"];
    "settings.local.json committed?" -> "Works for user only" [label="no"];
    "Works for user only" -> "Share with team?";
    "Share with team?" -> "Override gitignore + commit" [label="yes"];
    "Share with team?" -> "Add to settings.local.json" [label="no"];
    "Override gitignore + commit" -> "Add to settings.local.json";
}

Check: git ls-files .claude/settings.local.json

To share with team, override gitignore:

gitignore
.claude/
!.claude/settings.local.json

Why commit: Team members get permissions automatically; worktrees don't inherit uncommitted files.

Permission Patterns

Bash                           # All bash commands
Bash(npm run build)            # Specific command
Edit                           # All file edits
Read(~/**)                     # Read files in home
Skill(plugin-name:*)           # All skills from plugin
Skill(plugin-name:skill-name)  # Specific skill
mcp__server                    # All tools from MCP server
mcp__server__*                 # All tools (wildcard, equivalent)
mcp__server__tool              # Specific tool from MCP server
WebFetch(domain:example.com)   # Specific domain

Known Issues (Jan 2026)

Path Prefix Gotcha (#6881)

Prefix Meaning Example
/path Relative to settings file /src/** → <settings-dir>/src/**
//path Absolute filesystem //Users/me/code/**
~/path Home directory ~/.config/**

Common mistake: /Users/me/... is NOT absolute — use //Users/me/...

Skill Permissions Broken (#5140, #10833)

Skill(*) doesn't work reliably anywhere:

  • User settings: sometimes ignored, worktree bug
  • Project settings.json: doesn't work at all
  • Project settings.local.json: works but blocks personal overrides

Team workaround: Commit settings.local.json with explicit skill patterns. See Skill Permissions above.

Skill allowed-tools Broken (#14956)

Skills with allowed-tools in frontmatter don't actually grant permissions. The skill loads, reports correct allowedTools, but Bash commands are still denied.

Workaround: Add patterns to global allow list directly.

Plugin Enable/Disable Ignored (#13344)

When plugins share a source directory, disabling one loads all skills anyway. enabledPlugins settings have no effect.

Impact: ~35-40k tokens wasted on unwanted skills.

User Settings Sometimes Ignored (#5140)

~/.claude/settings.json permissions may not apply. Same rules work in project .claude/settings.local.json.

UI Grant Overwrites List (#9814)

Clicking "don't ask again" can overwrite entire permissions array with single new entry.

Workaround: Backup settings before using UI grants, or prefer manual edits.

Bash Wildcards + Env Vars (#8581)

Bash(cmd:*) fails to match commands with env var prefixes like NODE_OPTIONS=....

Plugin-Scoped Permissions Not Planned (#10093)

Feature request for plugin-level permissions was closed as NOT_PLANNED (Jan 2026).

Notes

  • * matches any characters; ** matches directory depth
  • Deny rules take precedence over allow
  • Project settings override user settings
