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 5.1 | $0.00000 | $0.00294 |
| Opus 5 | $0.00000 | $0.00147 |
| Sonnet 5 | $0.00000 | $0.00059 |
| Haiku 4.5 | $0.00000 | $0.00029 |
Grade A, and why
ryk-protect 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 6d 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
ryk-protect
Explain how to run the current Codex workflow under ryk protection.
When to use
Use this skill when you want to ensure the current Codex session or command runs inside ryk supervision.
Strongest protection
The strongest local protection is running the Codex process itself through ryk:
ryk run -- <codex-command>
If the exact Codex invocation is unknown, run the Codex CLI through ryk using the command you normally use to start Codex.
What the plugin provides
The Codex plugin adds:
- Native skills for doctor, init, protect, redteam, and replay.
- Lifecycle hooks that call
ryk hook codex <event>for safety checks.
Important limitation
The Codex plugin adds native skills and lifecycle hooks. The strongest protection remains running the agent process through
ryk run.
Hooks are advisory and additive. They do not replace the supervision that ryk run provides over the child process.
Quick check
Verify ryk is ready:
ryk plugin doctor codex
Notes
- This skill does not modify host configuration.
- The plugin does not collect telemetry. A user-invoked
ryk runwrapper may record only fixed anonymous CLI metadata; seedocs/telemetry.md. - Hooks call the ryk CLI; they do not duplicate policy logic.
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.

ryk-protect is a skill published in the GitHub repository christopherkarani/ryk (39 stars, last pushed 16d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 294 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.
