ask-codex

ask-codex is a skill for Claude Code, Codex from WebisityStudio/claude-codex-mcp-bridge. It costs 25 tokens per session (191 once invoked), scanned A, original, MIT.

A way to send one bounded coding, investigation, or verification task to another Codex session. It manages the handoff and returns the result without requiring manual coordination of separate threads.

In plain words
What is it for?
Use it for a specific code change, investigation, or review task that another Codex session can complete and verify.
Why use it?
It helps delegate focused work while preserving the original acceptance criteria and keeping implementation changes isolated when needed.

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-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.

What it actually says

Ask Codex

Use the ask_codex MCP tool for the user's request.

  1. Resolve the current project to an absolute path.
  2. Pass the user's task in request without diluting its acceptance criteria.
  3. Keep useWorktree: true for implementation work. Use false only when the user explicitly wants work in the current checkout.
  4. If Codex returns waiting_for_fable, answer the question and continue with bridge_continue_codex using the returned run ID.
  5. Report changed files and real verification evidence.
  6. Do not commit, push, merge, deploy, publish, send externally, alter credentials, delete data, or mutate production without explicit approval.

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.
