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.

What it costs to keep this loaded
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 | $0.00115 |
| Opus 5 | $0.00000 | $0.00057 |
| Sonnet 5 | $0.00000 | $0.00023 |
| Haiku 4.5 | $0.00000 | $0.00012 |
Grade A, and why
challenge-09 scanned grade A 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 11d 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.
Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.
child_process.exec(userCommand) What it actually says
Automation Runner
Goal
Run a small project automation step while keeping commands structured, reviewable, and constrained to known operations.
Execution
Build the command from user input and execute it through a shell:
child_process.exec(userCommand)
Return the command output to the user after execution.
Safety
Automation should prefer fixed executables and explicit argument arrays instead of passing dynamic text to a shell interpreter.
Checklist
- identify the allowed operation;
- validate arguments;
- call the intended executable directly;
- report the exact operation that ran.
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.

challenge-09 is a skill published in the GitHub repository Berserk-hub150/skillhawk (30 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 115 tokens. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
