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 | $0.00017 | $0.01413 |
| Opus 5 | $0.00009 | $0.00707 |
| Sonnet 5 | $0.00003 | $0.00283 |
| Haiku 4.5 | $0.00002 | $0.00141 |
Grade A, and why
codex 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 5d 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.
This is a copy
100% identical to codex — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codex CLI
Delegate coding tasks to Codex via the Hermes terminal. Codex is OpenAI's autonomous coding agent CLI.
When to use
- Building features
- Refactoring
- PR reviews
- Batch issue fixing
Requires the codex CLI and a git repository.
Prerequisites
- Codex installed:
npm install -g @openai/codex - OpenAI auth configured: either
OPENAI_API_KEYor Codex OAuth credentials from the Codex CLI login flow - Must run inside a git repository — Codex refuses to run outside one
- Use
pty=truein terminal calls — Codex is an interactive terminal app
For Hermes itself, model.provider: openai-codex uses Hermes-managed Codex
OAuth from ~/.hermes/auth.json after hermes auth add openai-codex. For the
standalone Codex CLI, a valid CLI OAuth session may live under
~/.codex/auth.json; do not treat a missing OPENAI_API_KEY alone as proof
that Codex auth is missing.
One-Shot Tasks
terminal(command="codex exec 'Add dark mode toggle to settings'", workdir="~/project", pty=true)
For scratch work (Codex needs a git repo):
terminal(command="cd $(mktemp -d) && git init && codex exec 'Build a snake game in Python'", pty=true)
Background Mode (Long Tasks)
# Start in background with PTY
terminal(command="codex exec --full-auto 'Refactor the auth module'", workdir="~/project", background=true, pty=true)
# Returns session_id
# Monitor progress
process(action="poll", session_id="<id>")
process(action="log", session_id="<id>")
# Send input if Codex asks a question
process(action="submit", session_id="<id>", data="yes")
# Kill if needed
process(action="kill", session_id="<id>")
Key Flags
| Flag | Effect |
|---|---|
exec "prompt" |
One-shot execution, exits when done |
--full-auto |
Sandboxed but auto-approves file changes in workspace |
--yolo |
No sandbox, no approvals (fastest, most dangerous) |
--sandbox danger-full-access |
No Codex sandbox; useful when the host service context breaks bubblewrap |
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 is a skill published in the GitHub repository pedroiff0/awesome-skills (1 stars, last pushed 9d ago), licensed MIT. It adds 17 tokens to every session and 1,413 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to codex, differing in 0 lines, and is treated as a copy.
