// Recommend safe Bash permissions for Elixir mix commands in settings.json. Use when permission prompts slow workflow, "fix permissions", "reduce prompts", "auto-allow mix".
Self-improving loop for plugin skills. Reads program.md, proposes one mutation per iteration, evaluates against deterministic scorer, keeps improvements via git, reverts failures. Targets weakest skill+dimension. Use with /loop for overnight runs.
Compute metrics for Claude Code sessions. Discovers via ccrider, filters trivial, computes friction/opportunity/fingerprint scores. Use for broad session triage.
Project health audit and health check — architecture, performance, tests, dependencies, code quality. Use when assessing overall project health, before releases, or after refactors.
Brainstorm Elixir/Phoenix features — explore ideas, compare approaches, gather requirements. Use when vague idea, not sure how to approach, or want to discuss before plan.
Analyze Elixir/Phoenix performance — N+1 queries, assign bloat, ecto optimization, genserver bottlenecks. Use when slowness, timeouts, or high memory reported.
Address PR review comments on Elixir/Phoenix code — fetch comments, draft responses, optionally fix code. Use when the user shares a PR URL or mentions reviewer feedback.

| argument-hint | [--days=14] [--dry-run] |
Scan recent session transcripts to find Bash commands you keep approving,
cross-reference with current settings.json, and recommend adding the missing ones.
Primary goal: Discover MISSING permissions from actual usage. Secondary goal: Clean up redundant/garbage entries.
/phx:permissions [--days=14] [--dry-run] — Scans session JSONL files, finds uncovered Bash commands, classifies risk, and recommends settings.json changes. Use --dry-run to preview without writing.
$ARGUMENTS — --days=N (default: 14), --dry-run (preview only).
rm, sudo, kill, curl|sh, mix ecto.reset, git push --force, chmod 777| Level | Examples | Action |
|---|---|---|
| GREEN | ls, cat, grep, tail, which, mkdir, cd, mix test/compile/credo/format, git status/log/diff | Auto-recommend |
| YELLOW | git add/commit/push, mix ecto.migrate, mix deps.get, npm install, docker build/run, source, mise exec | Recommend with note |
| RED | rm -rf, sudo, kill, `curl | sh,mix ecto.reset/drop,git push --force,git reset --hard` |
Run the extraction script from ${CLAUDE_SKILL_DIR}/references/extraction-script.md.
This scans all project JSONL files from the last N days, checks each Bash command
against current settings.json patterns, and reports uncovered commands with counts.
IMPORTANT: Run this FIRST. Do NOT skip to settings cleanup.
For each uncovered command from Step 1 output:
Bash(base_command *) format
(use SPACE before *, NOT colon — :* is deprecated)
mkdir -p (94x) → Bash(mkdir *)mise exec (39x) → Bash(mise *)tail -5 (20x) → Bash(tail *)Bash(done), Bash(fi),
Bash(__NEW_LINE_*), partial heredocs, entries covered by broader patterns:* patterns — replace any Bash(name:*) with Bash(name *)
(space before *). The :* suffix is deprecated and may not match reliablyPresent a combined table:
## Permission Recommendations (last N days)
### ADD — Missing permissions (from session scan)

### REMOVE — Redundant/garbage entries
| Entry | Reason |

### RED — Require manual approval (not adding)

--dry-run)Walk through findings interactively using AskUserQuestion. Present items
in batches by risk level, starting with GREEN (safest):
Batch 1 — GREEN items (read-only, tests, safe tools):
Use AskUserQuestion with options:
Batch 2 — YELLOW items (write ops, need caution):
Always show individually — one AskUserQuestion per item with options:
Batch 3 — REMOVE candidates (garbage/redundant):
Use AskUserQuestion with options:
Track approved items in a list. After triage, show final summary of what will be added/removed and ask for confirmation.
Merge approved additions into ~/.claude/settings.json under permissions.allow.
Remove approved garbage entries. Report final counts.
