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 | $0.02694 |
| Opus 5 | $0.00000 | $0.01347 |
| Sonnet 5 | $0.00000 | $0.00539 |
| Haiku 4.5 | $0.00000 | $0.00269 |
Grade C, and why
codex-companion-protocol scanned grade C with 2 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.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.

Expected in a hook, worth knowing in a rule or an instructions file.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
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.

codex-companion-protocol is an agent published in the GitHub repository maxritter/pilot-shell (2,063 stars, last pushed yesterday), with no licence file. It costs nothing until one of its globs matches a file; then it loads 2,694 tokens. A static security scan graded it C with 2 findings (harvests environment variables, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
