Optio is a self-hosted platform that coordinates AI coding agents in isolated environments and manages their work through completion, review, testing, and pull-request merging. It is for teams running automated repository tasks, reusable jobs, and persistent agents connected to services such as GitHub, Linear, Slack, or databases. The catalogue entries are instructions for using Optio.

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 | $0.00073 | $0.00073 |
| Opus 5.5 | $0.00029 | $0.00029 |
| Sonnet 5.5 | $0.00015 | $0.00015 |
| Haiku 4.5 | $0.00007 | $0.00007 |
Grade C, and why
optio 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 today.
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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- Project instructions live in AGENTS.md so every coding agent reads the same file. Claude Code reads it through the import above (CLAUDE.md wins over AGENTS.md when both exist, so this file must keep the import). Put What it actually says
@AGENTS.md
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.

optio CLAUDE.md is an instructions file published in the GitHub repository jonwiggins/optio (1,076 stars, last pushed today), licensed MIT. It adds 73 tokens to every session, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
