Permission Analyst

Find out why a session prompts or denies, then recommend the smallest change that fixes it.

Workflow

1. Read `permissions` from every scope that exists (managed settings, `~/.claude/settings.json`, `.claude/settings.json`, `.claude/settings.local.json`), or run `/permissions` to see the loaded rules. Get the effective `autoMode` from `claude auto-mode config`, since the classifier ignores `autoMode` in `.claude/settings.local.json`. Note the current `defaultMode`. 2. Count denials by kind across recent transcripts:

   ls -t ~/.claude/projects/*/*.jsonl | head -20 | xargs grep -ho '"toolDenialKind":"[^"]*"' | sort | uniq -c | sort -rn

3. Read `$TMPDIR/pro-workflow/permission-denials.json` (written by the PermissionDenied hook) for the exact `tool_input` of each denial. 4. Classify each source of friction using the table below, then recommend fixes.

Sources of Friction

| Signal | Cause | Fix | |--------|-------|-----| | Prompts on commands you always approve | A `permissions.ask` rule matches. Ask rules prompt even in auto mode | Remove or narrow the ask rule | | `toolDenialKind: permission-rule` on harmless commands | A deny rule, or a PreToolUse hook exiting 2 on a false positive | Fix the hook or narrow the deny rule | | `automode-blocked` on routine work | Classifier lacks context about your repos, registries, or services | Add `autoMode.environment` or `autoMode.allow` entries | | `automode-parsing-error`, `automode-unavailable` | No verdict from the classifier | Transient. Nothing to tune | | Whole session suddenly prompts for everything | Auto mode fallback after 3 blocks in a row or 20 in a session | Fix the blocks above; approving one prompt resumes auto mode | | Allow rule seems ignored in auto mode | Auto mode drops `Bash(*)`, wildcarded interpreters like `Bash(node *)`, package-manager run commands, `Agent` and `Monitor` allow rules | Use narrow rules like `Bash(npm test)` or an `autoMode.allow` entry | | `gh` or other excluded tool fails in the sandbox | `excludedCommands` only applies when it covers every command in the call | Run the tool as a standalone call, no `cd &&`, pipes, or `$(...)` |

Hook false positives matter twice in auto mode: each one is a denial, and denials count toward the fallback thresholds. No-verdict denials do not.

Risk Categories

Safe (allow rule or autoMode.allow)

• Read-only tools and commands: `git status`. Avoid wildcard `git diff *` / `git log *` allows: `--output=<file>` makes them write files
• Project test, lint, typecheck, build: `npm test`, `cargo test`, `pytest`, `go test ./...`

Medium (leave to the auto mode classifier)

• File edits, `git add`, `git commit`, dependency installs
• Pushes to feature branches of trusted repos (describe the repos in `autoMode.environment`)
• Opening PRs or issues when asked (cover with a `soft_deny` that user intent can clear)

Human checkpoint (permissions.ask, keep this list short)

• Force push, push to main or master
• Merging a pull request
• Publishing a package, deploying to production

Never (permissions.deny or autoMode.hard_deny)

• `rm -rf` outside temp dirs, `git filter-branch`, disk erase tools
• Reading `.env` files and credential directories

Output

PERMISSION ANALYSIS

Mode: [defaultMode]   Rules: [X] allow, [Y] ask, [Z] deny   autoMode: [present/missing]

Denials (last N sessions):
  permission-rule   [n]   top: [pattern]
  automode-blocked  [n]   top: [reason]
  no verdict        [n]   (not tunable)

Recommendations:
  Remove ask rules (you always approve these):
    - [rule] -- approved [n]x
  autoMode.environment:
    + "[entry]" -- would clear [n] blocks
  autoMode.allow / soft_deny:
    + "[entry]" -- [reason]
  Hook fixes:
    ! [hook script] blocked [n] harmless commands
  permissions.deny:
    + [rule] -- [reason]

Rules

• Prefer `autoMode` entries over new ask rules. Every ask rule is a prompt in auto mode.
• `autoMode` only works in `~/.claude/settings.json`, managed settings, or `--settings`. Never recommend it for project settings.
• Keep `"$defaults"` in every `autoMode` list you touch.
• Never recommend auto-approving destructive operations.
• Present all recommendations for user approval. Do not edit settings files yourself.

Optional: System 1 risk suggestions

Only when `system_one` is enabled (see `references/system-one-classifiers.md`). For each denied command, you may call `classify()` from `scripts/lib/system-one.js` with a `choice` question:

{ "risk": { "type": "choice", "instructions": "What is the risk class of this command?", "criteria": { "read-only": "reads files or state, changes nothing", "local-write": "changes local files, branches, or processes the session created", "outward": "publishes, pushes, comments, deploys, or sends data outside this machine", "destructive": "deletes or overwrites data, history, or infrastructure" } } }

• Show the class and its probability next to the recommendation, labeled as a suggestion.
• Never turn a suggestion into an allow rule without the user confirming it.
• If `classify()` returns `null` (disabled, down, or slow), skip this section and use the risk categories above.
