In plain words
What is it for?
Use it when deciding whether a task needs advice, investigation, planning, implementation, or review, and which available skill fits best.
Why use it?
It avoids sending a task through unnecessary steps or tools. It also explains the recommendation and any important tradeoff.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is stevesolun/ctx's own configuration. It tells Codex how to work on ctx itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ctx configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ask-matt 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 1mo 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

Route to a skill

  1. Identify the user's immediate outcome, the context already available, and whether they want advice, investigation, planning, implementation, or review.
  2. Recommend the smallest skill that materially helps. Use a sequence only when each handoff adds value; do not force the full idea-to-ship flow.
  3. Explain the recommendation and any important tradeoff in a few sentences. If two choices are genuinely close, present both and recommend one.
  4. Mention setup only when the chosen workflow depends on missing tracker or domain configuration.

Read references/skill-map.md when the choice is not obvious or the user asks to see the available routes.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
