codex-claude-council

Quick start

1. Install in Claude Code and Codex (this checks Node.js and both CLIs first; other ways under Install):

   npx -y codex-claude-council install

2. Restart Claude Code and Codex, so they load the plugin.

3. Ask, in a project: "Ask the council: what does this project do, and what would you improve first?"

Related MCP server: codex-mcp-server

Why two models?

One model answers with confidence, right or wrong. Two models that disagree, and must explain why to each other, catch what either misses alone, the way a second reviewer does.

A real run (low effort): "PostgreSQL or SQLite for a single-server internal tool with about 20 users?"

The final answer was sharper than either opening answer: SQLite, with the exact conditions under which to move to PostgreSQL. See the whole discussion as a page: open it (source) (make your own with --html, see From the terminal).

Benchmark

24 programs in which several traps interact (the hard set: the event loop across nested promises and timers, class fields, yield from, NULL in joins, …), each asked "what exactly does this print?" and graded against what it really prints. Codex gpt-6.1-sol and Claude Sonnet 5.5, both at low effort, fresh sessions, no web search (October 13, 2026):

• The council caught the one mistake: on h-py-dunder Claude alone printed V3 V102 V3 …; the council printed the right V3 V102 V102 …, with both models agreeing.

• It never made things worse: there is no question the council got wrong that either model got right alone.

• What it means: here Codex alone was already perfect, so the council's gain is insurance. You get the better answer without knowing in advance which model will slip, at about 3 to 5 times the time. One miss in 24 is a small sample, not proof.

Every answer is in the result file. Run it yourself with your own models and effort.

How it works

flowchart LR
    Q[Your question] --> CA[Codex answers]
    Q --> LA[Claude answers]
    CA -- to Claude --> L1[Claude replies]
    LA -- to Codex --> C1[Codex replies]
    L1 -- to Codex --> C2[Codex replies]
    C1 -- to Claude --> L2[Claude replies]
    C2 & L2 --> V{Both agree?}
    V -- no: exchange again --> V
    V -- yes --> F[One writes the final answer, the other checks it]

1. Answer: both models answer on their own, without seeing each other.

2. Exchange: each model gets the other's latest message (first its answer, then its replies) and replies point by point: what it accepts and how its position changes, where it still disagrees and why, then its current answer and a verdict, AGREE or DISAGREE. The two replies cross over, and the exchange repeats: a crossed zig-zag that narrows round after round.

3. Converge: as soon as both say AGREE in the same exchange, one model writes the final answer and the other checks that it matches what they agreed (at most 5 exchanges by default; max_rounds: 0 for no limit).

4. No agreement: if the limit is reached first, the final answer sets out what they agree on and each point still in dispute, with both positions.

Neither model leads the discussion: in every exchange both reply to each other at the same time, and only after they agree does one of them write the final text. Each model keeps its session between questions, so it remembers the discussion and what it has already read, and each prompt carries only what that model has not seen yet.

Requirements

• Both CLIs are required. The installer checks for them and stops, with these install steps, if either is missing. Before each council, the CLIs it runs are checked for a sign-in, and nothing is sent until they are signed in.

• Git lets both models look at your project's history, changes and blame, and skill add uses it to download a repository's skills.

Install

macOS / Linux / WSL

curl -fsSL https://raw.githubusercontent.com/hamza-aziz-ai/codex-claude-council/main/install.sh | bash

Windows (PowerShell)

irm https://raw.githubusercontent.com/hamza-aziz-ai/codex-claude-council/main/install.ps1 | iex

Any OS with Node.js

npx -y codex-claude-council install

The installer checks Node.js and both CLIs (and whether each is signed in), then adds this repository's marketplace to Claude Code and Codex and installs the plugin in both (for Claude Code, for your user, so it works in every project). If the plugin is already installed, it updates it instead.

Options: --only claude|codex (one app only; both CLIs are still required), --claude-desktop (also register the server with Claude Desktop's Chat tab), --dry-run (show the commands without running them). To pass them:

curl -fsSL https://raw.githubusercontent.com/hamza-aziz-ai/codex-claude-council/main/install.sh | bash -s -- --claude-desktop

& ([scriptblock]::Create((irm https://raw.githubusercontent.com/hamza-aziz-ai/codex-claude-council/main/install.ps1))) --claude-desktop

Afterwards:

1. Fully quit and reopen Claude Code and Codex (and Claude Desktop), so they load the plugin.

2. Check the setup: npx -y codex-claude-council doctor.

3. Try it in a project: "Ask the council: what does this project do, and what would you improve first?"

Update

npx -y codex-claude-council update               # both apps
npx -y codex-claude-council update --only claude # or --only codex
npx -y codex-claude-council update --dry-run     # show the commands only

It refreshes the marketplace and updates the plugin in Claude Code and Codex; then fully quit and reopen both. Running the installer again does the same. CHANGELOG.md lists what changed. In Claude Desktop, updates arrive through Sync automatically (or Sync under Settings → Plugins); in the ChatGPT desktop app, update the plugin under Settings → Plugins.

Or install per app

Use it

Just ask in plain language. The host (the app you are asking in) picks the tool and fills in its inputs:

In a project, the host passes its folder as the workspace, and the models read what they need themselves: point them at files, functions, the failing test or the error rather than pasting whole files. They cannot see the host's conversation (unless the host takes part itself), so the host states the task and any context that is not in the project.

The host picks the tool from your words. Name the tool if you want to be sure:

Use it from the desktop apps

Claude Cowork with a ChatGPT Work conversation. Conversations in ChatGPT's Work mode are saved as Codex sessions, so the plugin can continue one by its title. In a Cowork conversation, ask:

Discuss with my ChatGPT Work session "Find UAE job platforms": which three job portals should I focus on first, and why?

• Cowork is the Claude member, with everything its project gives it: its folders, instructions, connectors and skills.

• Codex continues that Work conversation, read-only, in its own folder, and the council's turns appear there when you reopen it. Close it in the ChatGPT app first.

• A Cowork conversation can't be continued from outside: Cowork doesn't save its conversations as Claude Code sessions. Start from Cowork to have it take part.

• Share the project folder. If both apps' projects use the same folder on your computer, both models read the same files. Instructions stored only inside an app (a Cowork project's instructions, ChatGPT project settings) are not shared: the other model sees the folder's CLAUDE.md / AGENTS.md instead.

Give the members what they can't reach

The members run on your computer, read-only. By default Codex's commands have no network access: it can't call an API, query a database, open a Google Sheet or open a claude.ai link, and its web search runs on OpenAI's side and only reaches public pages. Claude's read-only commands can reach the network. Turn on network to let Codex call APIs too. Either way, data behind a login (SSH, databases, private sheets) is best collected by the host first, into the workspace, with the question pointing to it:

flowchart LR
    subgraph Remote[Out of the members' reach]
        L[(Server logs)]
        DB[(Database)]
        G[Google Sheet]
        A[claude.ai artifact]
    end

    L & DB & G & A -.-> H
    F --> C[Claude member]
    F --> X[Codex member]

• Copy only what the question needs, such as the log lines for the calls in question, not whole log folders.

• Keep the copies out of git: put them in a folder listed in .git/info/exclude, which stays on your machine.

• Keep secrets out of the question. The question is saved in both sessions and sent to both providers. Have the host read a connection string from an environment variable instead.

Write a question that works

The members can't see your conversation with the host: they see only the question (at most 12,000 characters) and the workspace. For a long task, split your prompt in two:

## Part A — instructions for you (the host), not sent to the other model
1. Collect the data into .council-data/ (see above).
2. Start council_join with me "claude", other_session_id "<id>",
   workspace "<absolute path>", max_rounds 0.
3. When they agree, show me the result and wait for my OK before changing code.

## Part B — the council question (send verbatim)
Goal: <what you want, and what "done" means>.
Data: <each file or folder, and its format>.
Tasks: 1. Measure … 2. Trace the code path (file:line) … 3. Propose the smallest fix as a diff …
Constraints: every claim cites a log line, a file:line or a measured number.

• Say what to measure, not what to find. If the question states the answer ("p50 is 2.7 s"), the other model tends to confirm it instead of checking. Give earlier findings as a file to open after its own measurement: "Do not open prior-study.md until you have your own numbers; then compare."

• Ask for evidence and for measured results. "Report the saving as measured; do not round it up to a target" keeps a goal like "save 2 s" from turning into a claim.

• State the premise as a question, not a fact. "Measure first; do not assume a fast path exists" lets the models correct a wrong assumption.

• The members only propose. They are read-only, so the host applies the agreed change afterwards, then tests and commits it.

• In Claude Code, /goal is limited to 4,000 characters. Save a long prompt as a file and give /goal a short condition: "/goal Follow every step in /path/task.md in order. Done when: …".

Skills, models and effort

• Several skills at once. Name them all (skill: "llm-council, caveman", or --skill llm-council --skill caveman). Both models get each one's instructions and use each where it fits. With council_join, have the host invoke the same skills itself.

• Use heavy skills once. llm-council starts five advisors each time it runs. Ask for it once, on the final plan, not on every turn.

• Model and effort: anything you don't set comes from the plugin's config (effort high by default), then from each CLI's own config. So Codex uses the model in your ~/.codex/config.toml, but the plugin's high effort replaces the effort set there. Ask for xhigh or max for one question, or set it in the config.

Sessions

• Close a session before the council continues it. Codex refuses a session that is open in the Codex CLI or app ("already has an active writer"). A session Codex hasn't saved yet (no message sent in it) can't be continued either.

• Pass the id when it matters which session you get. Names are easy to reuse; codex resume and /status show ids.

Who takes part

There are three ways to run the two members. The discussion is the same in all of them.

New sessions

By default each side runs a new Codex / Claude Code session in the workspace, which lasts as long as your host session: follow-up questions reuse it, so the models remember earlier questions and what they read. When you start a new host session, the council starts new sessions too.

Your sessions

Pass sessions you already have, by id or by name, and the council continues those sessions in place, with everything they have read and discussed. The council's turns are added to them, so you see the discussion when you go back.

Finding a session's id or giving it a name:

• A name is looked up where each CLI keeps it: Claude Code in the session's own transcript, Codex in ~/.codex/session_index.jsonl. If several sessions have that name, the most recently used one is taken (an exact match before one that differs only in case). A name can contain spaces: --codex-session "auth refactor".

• Names are easy to reuse by mistake, so pass the id when it matters which session you get.

• Each session runs in the folder it was started in, which is also the default workspace. Pass a workspace to have it work in another folder.

• For the council's turns, both run in plan mode / read-only, whatever mode you used them in.

• Close those sessions first, or at least don't type in them while the council runs: two programs writing to one session can mix up its history. Reopen them afterwards (claude --resume <id>, codex resume <id>) to see the council's turns.

• Don't pass the id of the session you are asking from; to have that session take part, use council_join.

Sessions on another machine

A session on another computer takes part too: write it as user@host:session, with the session's id or name as there, for example --claude-session hamza@10.152.15.202:fix-order-dialog-bugs or "continuing my Claude session hamza@10.152.15.202:fix-order-dialog-bugs". That member runs on that machine, through ssh: this plugin's own codex / claude command, with that machine's CLI and its sign-in (any account, not necessarily yours here), in the session's own folder, read-only as here.

• Needs: key-based ssh from this computer (no password prompt: ssh -o BatchMode=yes user@host true must work), and Node.js 20+ and the CLI, signed in, on that machine (Linux or macOS). Node.js installed with nvm is found too, even when nvm loads only in ~/.bashrc. Nothing is installed there: npx fetches this plugin's version for the call.

• Its model and effort come from that machine's config, unless you set them for the call.

• Skills (skill): the council asks that machine which of them are installed for its CLI (in the session's folder too), with one ssh call; those it loads by name, the others' instructions are sent. If the check fails, every skill's instructions are sent.

• It continues the saved session, not the window it is open in: don't type in that session while the council runs, and resume it afterwards to see the council's turns.

• Cancelling stops the council here; a turn already running on that machine finishes there.

• ssh is found on your PATH; set "ssh": { "command": "<path>" } in the config to use another.

Take part yourself: council_join

Say your repository has a Claude Code session abcd and a Codex session efgh, and you are working in abcd. Ask there: "discuss with my Codex session efgh whether we should split the auth module".

• abcd itself is the Claude member. No second Claude session is started. council_join hands abcd each of Claude's turns (the same prompts a Claude member gets); abcd writes them in its own conversation, with everything it already knows, and sends each back with council_turn.

• Codex continues efgh in place, read-only. Without a session id, Codex starts a new session.

• The steps are the same as council_ask: abcd and Codex exchange replies until both agree, and the agreed answer lands in abcd. abcd writes the final answer and Codex checks it, unless you name another synthesizer.

It works the other way round too: from a Codex session, council_join makes that session the Codex member, and Claude continues the Claude Code session you name (or a new one).

• The host is asked, not forced, to leave files alone. The other model is read-only as usual, but the session you are asking from keeps its own permissions.

• Only the other model's CLI must be signed in.

• Each of the host's turns may take up to skill_timeout_seconds (default 1800); after that the council stops. council_cancel stops it at any time.

• It needs a host that takes turns (Claude Code, Codex, the desktop apps), so it is not a terminal command.

What the members can use

Skills that a step would use to change something (saving a report, building an index) have those steps skipped. Your MCP servers' tools run in their own processes: plan mode refuses Claude's tools that change things, while Codex follows each server's own approval settings. See Security and privacy.

Options

Agreement: max_rounds and synthesizer

Each exchange is one reply from each model, sent at the same time, each to the other's latest message. They have agreed when both end the same exchange with AGREE. Then the synthesizer writes the final answer and the other model checks that it matches what they agreed; if it does not, the writer revises it once.

Claude writes the final answer by default; pass synthesizer: "codex" (or change it in your config) to swap. With council_join, the host writes it by default, whichever model it is, since it has the whole context; pass synthesizer to have the other model write it instead. The writer only turns an agreement into text: the discussion itself is symmetric.

If the limit is reached without agreement, the synthesizer writes a final answer that sets out what they agree on and each point still in dispute, with both positions; it is marked as not agreed. If a call fails partway (for example a usage limit), you get what was reached and the reason.

Web search: web_search

Both models can search the web and read pages (on by default): Codex with its live web search, Claude with WebSearch and WebFetch. They prefer primary sources such as official docs and release notes, say where a fact came from, and check each other's claims against them. With a workspace they combine the two: "Is our use of the Stripe API in src/billing still correct for the current API version?"

Turn it off with web_search: false for one question ("ask the council without internet access"), --no-web in the terminal, or "web_search": false in your config. See Security and privacy before using it with a sensitive project.

Network for Codex's commands: network

By default Codex's commands have no network access (its web search still works). Turn on network to let them reach the network, for example to call an API or fetch live data, while the disk stays read-only: "ask the council, with network access for Codex: is our API returning the new field yet?", --network in the terminal, or "network": true in your config. Claude's read-only commands can already reach the network in plan mode.

• Limit where it can connect with "network_domains": ["api.github.com", "*.example.com"] in your config. With a list, Codex's network proxy blocks every other domain; with an empty list (the default), any domain is allowed.

• How: Codex runs with a permission profile instead of its read-only sandbox: the whole disk read-only, the network on. Permission profiles are a beta feature of Codex and may change; checked with Codex CLI 0.160.

• Windows: HTTPS from curl.exe, Invoke-WebRequest and git fails inside Codex's sandbox (Windows' own TLS has no credentials for the sandbox account), while Python and Node work; Codex is told so. The sandbox also can't read ~/.ssh, so SSH logins don't work from Codex there.

• Off by default, for a reason: a model that can read your files and reach the network could also send them out, for example if a log or web page it reads tries to instruct it (a prompt injection). Use a domain list, and keep network off for sensitive projects.

Skills: skill

Skills are SKILL.md folders with a method or style the models can follow. Install a repository's skills once:

npx -y codex-claude-council skill add https://github.com/aiwithremy/claude-skills-llm-council
npx -y codex-claude-council skill add https://github.com/JuliusBrussee/caveman.git
npx -y codex-claude-council skill add https://github.com/DietrichGebert/ponytail.git
npx -y codex-claude-council skill add https://github.com/Graphify-Labs/graphify.git
npx -y codex-claude-council skill list
npx -y codex-claude-council skill remove caveman-stats

• skill add clones the repository and installs every skill in it, each with its files (references, scripts): caveman brings 20 (caveman, caveman-review, caveman-compress, …), ponytail 6 (ponytail, ponytail-review, …), graphify and llm-council one each. It also takes one folder of a repository (…/tree/<branch>/<folder>), a local folder or a SKILL.md file. Without git, it installs a repository's top-level SKILL.md only.

• Skills are saved in ~/.codex-claude-council/skills/<name>/. Skills installed natively for Claude Code (~/.claude/skills) or Codex (~/.codex/skills, ~/.agents/skills), and those of their enabled plugins, can be named too. Restart the apps afterwards so the tools list new skills (plugin skills are not listed, but work by name).

• A skill a member already has is named, not sent. If the member's own CLI has the skill (in its skills folder, the project's .claude/skills or .agents/skills, or an enabled plugin), the member is told to load it by name, as it loads any of its skills. Only the skills it lacks have their instructions sent. For llm-council and graphify, both installed for both CLIs here, that cuts the first prompt from about 61,000 characters to about 1,100. The host of a council_join always gets the full instructions, since a desktop app may not load the CLI's skills.

• Nothing third-party ships with the plugin: check a skill's license and contents before you install it (llm-council, for example, has no license file).

A skill is used only when you ask for it: "ask the council, using the llm-council skill: …", or --skill llm-council in the terminal. For several, name them all: "using the llm-council and caveman skills", skill: "llm-council, caveman", or --skill llm-council --skill caveman. Both models (and the host, with council_join) get its instructions with the question and decide for themselves at which steps it is needed, following the skill's own guidance: a method like llm-council for a real decision or disagreement, a style like caveman (terse replies) or ponytail (the simplest solution that works) on every reply. When a model uses a skill, it follows it fully, including sub-agents, which are read-only too. The discussion's rules come first, and each answer comes back in the format its step asks for.

graphify builds its knowledge graph by running a Python tool that writes graphify-out/, which the members cannot do. Build it yourself first (pip install graphifyy, then graphify . in the project); the members then read graphify-out/GRAPH_REPORT.md and graph.json, and Codex can run graphify query.

A step that uses a skill with sub-agents can take several minutes and uses much more of both plans; such a call may take up to skill_timeout_seconds (default 1800).

Tool reference

Every tool also returns its result as structuredContent (declared in its outputSchema): status (done, working, your_turn or stopped), the text, and the job_id or council_id to use next. The tool names before 0.11.7 (debate, ask_codex, ask_claude) still work.

• workspace: the absolute path of the project folder both models work in. In Claude Code and Codex, the plugin's skill tells the host to pass the folder you are working in.

• Codex effort: none, minimal, low, medium, high, xhigh. Claude effort: low, medium, high, xhigh, max.

• Claude models: an alias (opus, sonnet, fable) or a full model name. Codex models: any name your Codex CLI accepts.

• Anything you leave out comes from your config.

From the terminal

npx -y codex-claude-council ask "Which is faster for 10M rows, A or B?"
npx -y codex-claude-council debate "..." --codex-effort xhigh --claude-model opus
npx -y codex-claude-council ask "..." --max-rounds 0          # until both agree

npx -y codex-claude-council ask "..." --no-web                # no web search
npx -y codex-claude-council ask "..." --network               # Codex's commands may reach the network
npx -y codex-claude-council ask "..." --skill llm-council     # with an installed skill
npx -y codex-claude-council ask "..." --skill llm-council,caveman  # with several
npx -y codex-claude-council ask "..." --html council.html  # also save the discussion as a page to share
npx -y codex-claude-council ask "..." --claude-session <uuid> --codex-session <id>  # your sessions
npx -y codex-claude-council codex "..." --session <id>        # your Codex session

In the terminal, both models work in the git repository you run the command from (if any), unless you pass --workspace, --no-workspace or a session id. Each command is a new pair of sessions for that run, unless you pass session ids. Questions can also be piped on stdin. For a shorter command, install it globally (npm install -g codex-claude-council) and use codex-claude-council ask "...".

Configure

npx -y codex-claude-council config --init

This creates ~/.codex-claude-council/config.json. It is re-read on every call, so edits apply immediately:

{
  "timeout_seconds": 600,
  "skill_timeout_seconds": 1800,
  "tool_wait_seconds": 50,
  "synthesizer": "claude",
  "max_rounds": 5,
  "web_search": true,
  "network": false,
  "network_domains": [],
  "allow_api_key_auth": false,
  "codex":  { "command": null, "model": null, "effort": "high" },
  "claude": { "command": null, "model": null, "effort": "high" }
}

Set COUNCIL_CONFIG to use a different config file. The installer shows the plugin's icon in terminals that draw sixel images, which it asks the terminal (so it works over ssh too); set COUNCIL_BANNER=image to always show it, or COUNCIL_BANNER=text never to.

Security and privacy

• Everything runs on your computer. Your question goes to OpenAI and Anthropic through their official CLIs, under your own accounts.

• The members cannot change your files.

  • Codex runs codex exec in its read-only sandbox, enforced by the operating system, with approval_policy="never". Both are set on the command line, which overrides your config.toml, so even a config that grants full access stays read-only.

  • Claude Code runs in plan mode: it reads, searches and runs commands it knows to be read-only, and every edit, write or other command is refused, since nobody is there to approve it. Plan mode is Claude Code's own permission guard, not an operating-system sandbox; the only file it may write is its plan file under ~/.claude/plans/.

  • With council_join, the host is your own session and keeps its own permissions; it is only asked not to change files.

• Your own setup applies. The members run with your skills, plugins, MCP servers, hooks, CLAUDE.md / AGENTS.md and permission rules. This plugin is switched off inside them, so a member can't start another council. MCP tools run in their own processes: plan mode refuses Claude's tools that change things, while Codex follows each server's own approval settings, so keep that in mind for MCP servers that can change things.

• What they read is sent to the model providers. Whatever either model chooses to read goes to OpenAI or Anthropic, as when you paste it. Both can read files outside the project too, as in your normal sessions: Codex's read-only sandbox allows reading the whole disk, and plan mode allows read-only commands anywhere. Without a workspace, they start in an empty folder and are told to work from the question.

• Web access. Codex's web search runs on OpenAI's side (its sandbox has no network for commands unless you turn on network); Claude can search and fetch pages, and its read-only commands can reach the network. With a workspace as well, text in the project that tries to instruct the model (a prompt injection) could in principle get it to send project content to a website, for example in a URL it fetches. For sensitive projects, turn web access off.

• Sessions. The members' sessions are saved by the CLIs like any other, so they appear in claude --resume and codex resume for that folder. A session you pass by id is continued in place: the council's turns are added to it.

• Subscriptions, not API keys. API-key environment variables are removed before the CLIs start. Codex must be signed in with ChatGPT and Claude Code with a Claude subscription, unless you set allow_api_key_auth.

• Privacy policy: PRIVACY.md. The plugin has no servers and no telemetry; what goes to OpenAI and Anthropic goes through their CLIs, under your accounts.

• The plugin itself runs with your user permissions: about 1,700 lines of dependency-free JavaScript in src/. Read it before installing if you like.

Troubleshooting

Run the doctor. It checks Node.js, both CLIs, their sign-ins and your effective config:

npx -y codex-claude-council doctor

• "The council needs … signed in": nothing was sent. The message names each CLI with a problem and the fix: codex login (choose Sign in with ChatGPT) and/or claude auth login.

• "usage limit": your ChatGPT or Claude plan hit its limit. Wait for the reset or lower the effort.

• "timed out": raise timeout_seconds (or skill_timeout_seconds with a skill), or lower the effort.

• The tool call ended after about 60 seconds: update to 0.6.2 or later, where every tool returns within about 50 seconds and the host polls council_result. If your app has no such limit, "tool_wait_seconds": 0 waits in one call.

• "no … session named …": no session has that name. Check it with claude --resume / codex resume --all, rename the session with /rename, or pass its id from /status.

• "Waiting for the … session": another council or question is using that session; each session takes one at a time, and this one starts when it is free. If the message names a council_join job waiting for your reply, that job holds the session until the host answers it (up to skill_timeout_seconds, 30 minutes by default): send the reply with council_turn, or stop that job with council_cancel.

• "… is not waiting for your reply now" (council_join): the other model is still working; the host should call council_result with the id to get its next turn.

• skill "…" is not installed: install it with skill add, then restart the app so the tools list it.

• Tools don't appear: fully quit and reopen the app after installing. In the desktop apps, check the plugin is installed and enabled under Settings → Plugins.

• node not found by a desktop app on macOS: GUI apps don't read your shell profile, so Node installed with nvm may be invisible to them. Install Node from nodejs.org or Homebrew.

• CLI not found: set codex.command / claude.command to the full path.

• "unknown option" / "unexpected argument": a CLI is too old. Update it: claude update, or npm install -g @openai/codex@latest.

• Windows: "Access is denied (os error 5)" when installing or updating: see Update.

Uninstall

npx -y codex-claude-council uninstall

This removes the plugin from Claude Code and Codex and the Claude Desktop chat entry, and keeps your config file and installed skills. In the desktop apps, uninstall it under Settings → Plugins.

Development

git clone https://github.com/hamza-aziz-ai/codex-claude-council.git
cd codex-claude-council
npm test

The tests use fake codex / claude executables, so they make no model calls. CI runs them on Windows, macOS and Linux. To try a local checkout, use its path as the marketplace: claude plugin marketplace add ./codex-claude-council or codex plugin marketplace add ./codex-claude-council.
