What it does

Codexbar is an agent skill from lizhelang/codexbar. Operate Codexbar's bundled CLI for OpenAI OAuth account login, import, listing, and activation. Use when the user mentions codexbar, OpenAI OAuth login, add account, activate account, or switch account.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering OAuth and OpenID Connect. It works with OpenAI. The repository describes itself as: macOS menu bar app for switching Codex providers and accounts without breaking shared session history. The licence is MIT.

When your agent uses it

The user mentions codexbar
OpenAI OAuth login
Activate account

Example prompts

“/codexbar”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

codexbarctl
/Applications/codexbar.app/Contents/MacOS/codexbarctl
Build from the repo

What it can do on your machine

Read from SKILL.md and the folder at commit 9f2e0f5. 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
Shell commands in SKILL.md call:
- xcodebuild
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Codexbar loads about 375 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 110 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~53
When it runs · the whole SKILL.md, loaded when a task matches: ~375

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); files beside SKILL.md are not scanned.

SKILL.md

Codexbar CLI Skill

Use this skill when the task is about operating Codexbar accounts or OAuth flows. Prefer the CLI over the GUI.

Resolve the binary

Use the first working path:

codexbarctl
/Applications/codexbar.app/Contents/MacOS/codexbarctl
Build from the repo:

bash

xcodebuild -scheme codexbarctl -destination 'platform=macOS' build

Then invoke the built binary from Xcode's product directory if needed.

Standard commands

Interactive human flow:

bash

codexbarctl openai login

Automation / AI flow:

bash

codexbarctl openai login start --json
codexbarctl openai login complete --flow-id <id> --callback-url <url> --json

If only the code parameter is available:

bash

codexbarctl openai login complete --flow-id <id> --code <code> --json

List accounts:

bash

codexbarctl accounts list --json

Activate an account:

bash

codexbarctl accounts activate --account-id <id> --json

Rules

Prefer openai login for a person in a terminal.
Prefer login start + login complete for AI or scriptable flows.
Do not hand-edit ~/.codex/auth.json or ~/.codex/config.toml if the CLI is available.
Never echo or summarize access_token, refresh_token, or id_token.
