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 | $0.00549 |
| Opus 5 | $0.00000 | $0.00275 |
| Sonnet 5 | $0.00000 | $0.00110 |
| Haiku 4.5 | $0.00000 | $0.00055 |
Grade A, and why
codex-do 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.
How it starts
The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Delegate Task to Codex
Delegate a well-scoped implementation task to Codex.
Instructions
You are delegating an implementation task to Codex. Follow these steps:
-
Parse the task from
$ARGUMENTS. If the argument is vague or missing, ask the user to be more specific before proceeding. -
Evaluate if the task is suitable for delegation:
- Good for Codex: repetitive bulk changes, boilerplate generation, test writing for existing code, migration scripts, file format conversions, well-defined single-file edits
- Keep for yourself: architectural decisions, cross-module refactoring, tasks requiring deep conversation context, ambiguous requirements, and trivial edits you'd finish faster yourself than you can write a spec for
- If the task is poorly scoped, explain why and suggest how to break it down.
-
Prepare a precise, self-contained prompt for Codex. Include:
- Exact file paths to create or modify
- The specific change required with examples if helpful
- Constraints (language, framework, coding style, naming conventions)
- What "done" looks like
-
Call the
codex_execMCP tool with:prompt: the prepared promptmode: "full-auto"requireGit: true
-
Review Codex's output critically:
- Run
git status --shortfirst to see ALL changes, including newly-created files (lines starting with??). Codex in full-auto mode often creates new files, andgit diffalone is blind to untracked files. - Run
git difffor modifications to tracked files, and read any new untracked files directly to review their contents. - Check for introduced bugs, regressions, or style violations
- Verify it matches the requested changes
- Verify it doesn't modify files outside the requested scope
- Run
-
Present the result with your assessment:
- What was done correctly
- What needs adjustment
- Apply changes only if they pass your review
- If issues found, offer to fix them yourself or re-delegate with refined instructions
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-do is a command published in the GitHub repository Arystos/skill-codex (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 549 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 2026-08-31.
