Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00304 |
| Opus 5 | $0.00000 | $0.00152 |
| Sonnet 5 | $0.00000 | $0.00061 |
| Haiku 4.5 | $0.00000 | $0.00030 |
Grade A, and why
mutate 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 2d 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
/mutate - Run Mutation Testing
Run mutation testing to evaluate test suite effectiveness.
Steps
- Detect the project language and testing framework from configuration files
- Check if a mutation testing tool is installed (Stryker for JS/TS, mutmut for Python, PITest for Java)
- If not installed, provide installation instructions for the appropriate tool
- Identify the source files and their corresponding test files
- Configure mutation operators: arithmetic, conditional, string, return value mutations
- Run the mutation testing tool on the target source files
- Monitor progress: total mutants generated, killed, survived, timed out
- Calculate the mutation score (killed / total * 100)
- List survived mutants with file location, line number, and mutation description
- For each survived mutant, identify which test should have caught it
- Suggest specific test cases to write for the top 10 survived mutants
- Save the mutation report to the reports directory
Rules
- Start with a single file or module to keep execution time reasonable
- Set a timeout per mutant of 10x the normal test execution time
- Exclude test files, configuration files, and generated code from mutation
- A mutation score below 80% indicates weak test coverage
- Focus on survived mutants in critical business logic first
- Do not count equivalent mutants (mutations that produce identical behavior)
- Report execution time and mutant count for performance tracking
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.

mutate is a command published in the GitHub repository aegntic/cldcde (11 stars, last pushed 5d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 304 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
