What it does
Local Codex is an agent skill from daymade/claude-code-skills. Launches and manages the local OpenAI Codex CLI as a non-interactive coding sub-agent via ChatGPT Pro OAuth, never API keys. Use to delegate coding tasks to Codex, run codex exec, generate or refactor code, or get a Codex code review; phrases like 'codex', 'run codex', 'codex exec', 'delegate to codex'.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts and reference files (for example `references/oauth-guide.md` and `scripts/codex_wrapper.py`).
It sits in Backend & APIs, covering OAuth and OpenID Connect, Subagents and Code review. It works with OpenAI. The repository describes itself as: Professional Claude Code skills marketplace featuring production-ready skills for enhanced development workflows. The licence is MIT.
When your agent uses it
- Delegate coding tasks to Codex
- Get a Codex code review
- Phrases like codex
- Delegate to codex
Example prompts
- “run codex”
- “codex exec”
- “delegate to codex”
- “/local-codex”
Requirements
- Python 3
- A credential in OPENAI_API_KEY
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 3c268d6. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
codexpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
OPENAI_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Local Codex loads about 1.6k tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 759 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.
Safety
Auto-check passed
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.

- description
- Launches and manages the local OpenAI Codex CLI as a non-interactive coding sub-agent via ChatGPT Pro OAuth, never API keys. Use to delegate coding tasks to Codex, run codex exec, generate or refactor code, or get a Codex code review; phrases like 'codex', 'run codex', 'codex exec', 'delegate to codex'.
Local Codex
Delegate coding tasks to the local OpenAI Codex CLI agent using your ChatGPT Pro subscription (OAuth, no API charges).
When to Use
- User wants to generate, refactor, or review code via Codex
- User wants to run
codex execfor non-interactive tasks - User wants to use Codex's GPT-5.5 agent capabilities
- User mentions "codex", "run codex", "delegate to codex"
Authentication (OAuth / ChatGPT Pro)
CRITICAL: This skill uses OAuth authentication from ~/.codex/auth.json (ChatGPT Pro flat-rate subscription). Do NOT set OPENAI_API_KEY or pass API keys — that would switch to pay-per-use billing.
- The ChatGPT.app desktop bundle and CLI share the same auth cache
- If auth fails, run
codex loginin terminal (browser OAuth flow) - For auth issues, see references/oauth-guide.md
Codex CLI Path
The skill auto-detects Codex CLI in this order:
CODEX_BINenv var, if set — explicit override. A non-executable path fails loudly instead of silently falling through to a different build (that would make whatever the wrapper measured unattributable).which codex— whatever is first on PATH. This is the build the surrounding environment actually runs, so it is the right default: npm global installs under nvm (~/.nvm/versions/node/*/bin/codex) resolve here./Applications/ChatGPT.app/Contents/Resources/codex— the copy bundled inside ChatGPT.app, fallback only. Its version tracks the Desktop app and can diverge from the npm build, so it is deliberately last.
If a bad CODEX_BIN was set, the wrapper exits 1 with
{"error": "CODEX_BIN not executable", "path": <value>} — the offending value is in
the error itself, and searched_paths is not emitted for this case (no other search
step ran). If neither PATH nor the app bundle has a codex, the wrapper exits 1 with
the actual search order in searched_paths.
Whichever binary wins, attribute behaviour to it by versioning the binary that
ran, not codex --version: the bare command always resolves the PATH copy, which is
the wrong build to quote when the fallback picked the app-bundled one. Use the
codex_path field from the wrapper's status output:
"<codex_path from status output>" --versionTwo builds on one machine is the normal state, not an anomaly.
Usage Patterns
1. Basic exec (single task)
python3 scripts/codex_wrapper.py exec "<prompt>" [<workdir>] [<model>] [<sandbox>] [<timeout>]Example:
python3 scripts/codex_wrapper.py exec \
"Write a Python function to calculate fibonacci" \
/tmp \
gpt-5.5 \
workspace-write \
3002. Code review
python3 scripts/codex_wrapper.py review [<workdir>] [<model>] [uncommitted:true] [<timeout>]Example:
python3 scripts/codex_wrapper.py review \
/path/to/repo \
gpt-5.5 \
true \
3003. Check status
python3 scripts/codex_wrapper.py statusOutput Format
The wrapper returns JSON with:
success: boolexit_code: intelapsed_seconds: floatstdout: raw outputstderr: error stream (truncated)parsed_jsonl: parsed JSONL events (if --json)final_message: extracted assistant text (if available)
Parameters
| Parameter | Default | Options |
|---|---|---|
| model | gpt-5.5 | gpt-5.5, gpt-5.5-pro, o4-mini, etc. |
| sandbox | workspace-write | read-only, workspace-write, danger-full-access |
| timeout | 300 | seconds (increase for large tasks) |
| json_output | true | always true (wrapper parses JSONL) |
Safety Notes
sandbox=read-onlyfor analysis/review tasks (no file writes)sandbox=workspace-writefor code generation (writes to working dir)sandbox=danger-full-accessonly when explicitly needed (full system access)- Always use
--skip-git-repo-checkwhen running outside git repos - Use
--ephemeralfor one-off tasks (no session persistence)
Show full SKILL.md (309 more words)Show less
Session Management
For multi-step tasks, Codex supports session resume:
# First step
codex exec --ephemeral "Step 1..."
# Later
codex exec resume --last "Step 2..."The wrapper currently runs single-shot exec. For multi-step workflows, use raw codex exec commands.
Limitations
- Desktop app must be running for OAuth token refresh (or token must be fresh)
codex doctorworks and is the first thing to run when Codex misbehaves. Run it without--summary—--summarycuts reachability down to a bare✗ reachability ... unreachableline (it actually prints twice, once under Notes and once under Connectivity) with no host and no remedy, in both the fail and the warning state. The full form names the host, the endpoint statuses, and a→ check proxy, ...remedy line, likewise in both states; what differs between fail and warning is which endpoint failed and whether it is marked(required). For--json, everything lives underchecks["network.provider_reachability"]:detailsmaps endpoint → status, andissuesis a list whose objects carryseverity/cause/measured/expected/remedy/fields(the last three are optional). Two traps: there is no top-levelissueskey at all — do not writereport["issues"](KeyError) orreport.get("issues")(silently None); and a check's ownissueskey is omitted entirely when empty rather than sent as[], socheck.get("issues")returns None for the 20+ checks that have nothing to report. Top level has exactly 5 keys,generatedAtis a string like"1790057704s since unix epoch"rather than a timestamp, and exit 1 fires on any failed check, not just reachability —rollout_db_parityis ⚠ on this install, and if it ever flips to fail it turns that exit code red for a reason unrelated to your network, which is what gates likecodex-1m-context-window-setup'sreturncode == 0check read. Verified 2026-09-22 on 0.155.1 (npm) and 0.155.0-alpha.9.2 (ChatGPT.app-bundled); the remedy wording quoted here is specific to those builds — upstream has since changed it.- Environment variables are NOT inherited into Codex's sandbox; pass via config or prompt

Can I use Local Codex in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add daymade/claude-code-skills --skill local-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/local-codex, .gemini/skills/local-codex, .github/skills/local-codex and .opencode/skills/local-codex in your project.
What does Local Codex need to run?
Going by SKILL.md and its folder, Local Codex needs Python for the scripts in its folder, the command-line tools its instructions call (codex and python3) and credentials named OPENAI_API_KEY. Our summary lists: Python 3; A credential in OPENAI_API_KEY.
Does Local Codex access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Local Codex safe to install?
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.
What licence does Local Codex use?
