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 | $0.01631 | $0.01631 |
| Opus 5 | $0.00816 | $0.00816 |
| Sonnet 5 | $0.00326 | $0.00326 |
| Haiku 4.5 | $0.00163 | $0.00163 |
Grade C, and why
ai-agent-skills CLAUDE.md scanned grade C with 1 finding 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 8d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- Original command: `rm -rf /some/path` How it starts
The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MUST
- MUST only communicate to me in ENGLISH, and start every reply with "Hi Leo, "
- Never commit unless asked. On "commit", auto-generate the message from the diff and commit immediately, no confirmation.
- NEVER create GitLab/GitHub MRs or PRs without being explicitly asked. Diagnosing or finding a fix does NOT mean create the MR -- only explain the fix and wait for an explicit instruction.
- Never push unless explicitly told to; after committing, ask before pushing.
- NEVER start implementing without completing the full planning workflow below. No exceptions.
- NEVER use typographic Unicode in authored content. Use ASCII only:
->(not the arrow char),-or--(not em/en dashes), straight quotes"'(not curly quotes),...(not the ellipsis char). Reason: skill/marketplace/flow files are JSON-serialized with ensure_ascii=True, so any non-ASCII char becomes an ugly\uXXXXescape. Applies everywhere (SKILL.md frontmatter/descriptions, JSON, commit messages, docs, prose), not just JSON.
Coding Principles & Workflow
The principles are the mindset; the workflow enforces them. Think before you type; do not skip steps.
The Four Principles
The mindset behind the workflow. Each is a one-line rule plus its test; the workflow below is how they get enforced per task.
| Principle | Guards against | The rule (and its test) |
|---|---|---|
| Think Before Coding | wrong assumptions, hidden confusion | State assumptions, surface tradeoffs, and ask when ambiguous or confused -- never pick an interpretation silently. |
| Simplicity First | overengineering, bloat | Minimum code that solves it -- no speculative features, abstractions, config, or error-handling for impossible cases. Test: a senior engineer wouldn't call it overcomplicated. |
| Surgical Changes | orthogonal edits | Touch only what the task needs; match existing style; don't refactor or "improve" unrelated code; remove only the orphans your change creates, never pre-existing dead code (mention it). Test: every changed line traces to the request. |
| Goal-Driven Execution | vague success, "make it work" | Turn the task into a verifiable goal -- tests-first (reproduce/validate, then make pass), a verify check per step, loop until proven. |
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.

ai-agent-skills CLAUDE.md is an instructions file published in the GitHub repository nphausg/ai-agent-skills (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 1,631 tokens to every session, about $0.0082 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
