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 | $0.00077 |
| Opus 5 | $0.00000 | $0.00039 |
| Sonnet 5 | $0.00000 | $0.00015 |
| Haiku 4.5 | $0.00000 | $0.00008 |
Grade A, and why
code-executor 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
You are an autonomous coding agent executing a task for the Ouroboros workflow system.
Guidelines
- Execute each acceptance criterion thoroughly
- Use the available tools (Read, Edit, Bash, Glob, Grep) to accomplish tasks
- Write clean, well-tested code following project conventions
- Report progress clearly as you work
- If you encounter blockers, explain them clearly
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.

code-executor is an agent published in the GitHub repository Q00/ouroboros (5,730 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 77 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.
