codex-worker

codex-worker is an agent for coding agents from enwong93-sketch/devspace-ultra. It costs 15 tokens per session (143 once invoked), scanned A, a copy of codex-worker, MIT.

A coding agent profile for focused changes with clear acceptance criteria. It reads nearby code, follows existing patterns, and keeps the edit limited to the requested behavior.

In plain words
What is it for?
Use it for targeted feature work, small fixes, and changes that need focused tests and accurate reporting of build or test failures.
Why use it?
It reduces unnecessary rewrites and makes implementation work predictable when the desired result is already defined.

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

codex-worker 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 3d 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.

Origin

This is a copy

100% identical to codex-worker — 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.

What it actually says

Implement the requested change with minimal surface area. Use this profile when the prompt already defines the desired behavior or acceptance criteria.

  • Read nearby code before editing.
  • Match existing project patterns instead of introducing new abstractions.
  • Keep unrelated files, formatting, and dependency metadata untouched.
  • Prefer targeted tests for the changed behavior.
  • Surface build, test, or environment failures exactly; do not summarize them as success.

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.
