Getting it into your agent

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00104 | $0.01869 |
| Opus 5 | $0.00052 | $0.00934 |
| Sonnet 5 | $0.00021 | $0.00374 |
| Haiku 4.5 | $0.00010 | $0.00187 |
Grade D, and why
claude-permissions-optimizer scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Claude Permissions Optimizer
Find safe Bash commands that are causing unnecessary permission prompts and auto-allow them in settings.json -- evidence-based, not prescriptive.
This skill identifies commands safe to auto-allow based on actual session history. It does not handle requests to allowlist specific dangerous commands. If the user asks to allow something destructive (e.g., rm -rf, git push --force), explain that this skill optimizes for safe commands only, and that manual allowlist changes can be made directly in settings.json.
Pre-check: Confirm environment
Determine whether you are currently running inside Claude Code or a different coding agent (Codex, Gemini CLI, Cursor, etc.).
If running inside Claude Code: Proceed directly to Step 1.
If running in a different agent: Inform the user before proceeding:
"This skill analyzes Claude Code session history and writes to Claude Code's settings.json. You're currently in [agent name], but I can still optimize your Claude Code permissions from here -- the results will apply next time you use Claude Code."
Then proceed to Step 1 normally. The skill works from any environment as long as ~/.claude/ (or $CLAUDE_CONFIG_DIR) exists on the machine.
Step 1: Choose Analysis Scope
Ask the user how broadly to analyze using the platform's blocking question tool (AskUserQuestion in Claude Code, request_user_input in Codex, ask_user in Gemini). If no question tool is available, present the numbered options and wait for the user's reply.
- All projects (Recommended) -- sessions across every project
- This project only -- sessions for the current working directory
- Custom -- user specifies constraints (time window, session count, etc.)
Default to All projects unless the user explicitly asks for a single project. More data produces better recommendations.
Step 2: Run Extraction Script
Run the bundled script. It handles everything: loads the current allowlist, scans recent session transcripts (most recent 500 sessions or last 30 days, whichever is more restrictive), filters already-covered commands, applies a min-count threshold (5+), normalizes into Bash(pattern) rules, and pre-classifies each as safe/review/dangerous.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

claude-permissions-optimizer is a skill published in the GitHub repository Jerrylalala/compound-engineering (5 stars, last pushed 3mo ago), licensed MIT. It adds 104 tokens to every session and 1,869 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it D with 2 findings (reads agent configuration directories, recursive force delete). It is 100% identical to claude-permissions-optimizer, differing in 0 lines, and is treated as a copy.
