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 | $0.00000 | $0.00261 |
| Opus 5.5 | $0.00000 | $0.00104 |
| Sonnet 5.5 | $0.00000 | $0.00052 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
IMPLEMENT scanned grade A with 0 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Implement a Feature or Bugfix
Overview
Use this command to implement a feature or bugfix.
- If on the
mainbranch, create a new branch for the feature or bugfix, otherwise ask the user if they want to create a new branch for the feature or bugfix or use the current branch. - Use the Github MCP server (or the Github (gh) skill) to understand the requirements of the feature or bugfix. If the user did not provide a Github issue URL, create a new issue with the details of the feature or bugfix.
- Don't assume you know everything about the request and ask for clarification on any details you are not 100% sure about.
- When you feel satisfied with the requirements, use the @test-driven-development skill to write the test first, watch it fail, write minimal code to pass.
- Once you are satisfied with the test and implementation, use the @test-and-lint command to run the tests and lint the code.
- If the tests or linting fail, fix the issues and repeat the process until the tests and linting pass.
- Once the tests and linting pass, use the @open-pr command to open a pull request with the changes in DRAFT mode.
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.

IMPLEMENT is a command published in the GitHub repository dep/agent-rules (11 stars, last pushed 4mo ago), licensed MIT.
