Collaborating With Codex is an agent skill from appautomaton/agent-designer. Delegate tasks to Codex CLI for prototyping, debugging, code review, implementation handoff, cross-model second opinions, and multi-turn Codex sessions via SESSIONID.
Its SKILL.md is about 3.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts, reference files and assets (for example `assets/prompt-template.md`, `references/cli-reference.md` and `references/handoff-patterns.md`).
It sits in Development, covering Prototyping. The repository describes itself as: Portable SKILLs workspace for Claude Code, Codex, and Gemini — issue-driven workflows and cross-agent collaboration via bridge scripts with session continuity.
Read from SKILL.md and the folder at commit b6e95dc. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
codexpython3gitFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
OPENAI_API_KEYFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Collaborating With Codex loads about 3.4k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 48 tokens; SKILL.md has 1,444 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,444 words (~3,372 tokens).
“Use Codex CLI as an independent collaborator while the primary agent remains responsible for verification, synthesis, and final user-facing decisions.”

Delegate tasks to Codex CLI for prototyping, debugging, code review, implementation handoff, cross-model second opinions, and multi-turn Codex sessions via SESSIONID. Collaborating With Codex is an agent skill from appautomaton/agent-designer. Delegate tasks to Codex CLI for prototyping, debugging, code review, implementation handoff, cross-model second opinions, and multi-turn Codex sessions via SESSIONID.
Collaborating With Codex fits situations like: tasks that involve Prototyping.
Run `npx skills add appautomaton/agent-designer --skill collaborating-with-codex -a claude-code`. Or copy the skill folder (skills/collaborating-with-codex in appautomaton/agent-designer) into .claude/skills/collaborating-with-codex in your project. Claude Code loads it when a task matches its description.
Run `npx skills add appautomaton/agent-designer --skill collaborating-with-codex -a codex`. Or copy the skill folder (skills/collaborating-with-codex in appautomaton/agent-designer) into .agents/skills/collaborating-with-codex in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add appautomaton/agent-designer --skill collaborating-with-codex -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/collaborating-with-codex, .gemini/skills/collaborating-with-codex, .github/skills/collaborating-with-codex and .opencode/skills/collaborating-with-codex in your project.
Going by SKILL.md and its folder, Collaborating With Codex needs Python for the scripts in its folder, the command-line tools its instructions call (codex, python3 and git) and credentials named OPENAI_API_KEY. Our summary lists: Python 3; A credential in OPENAI_API_KEY.
SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
No licence was found for Collaborating With Codex or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
About 3.4k tokens (SKILL.md is roughly 13k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 8k tokens, read only when the agent opens those files.
