Five independent advisors. One clear recommendation.
Council is a skill that helps you make decisions. Ask a question about your project. Five independent advisors weigh in. The Chairman brings it all together. Your agent adds its own take and next step.
Use it for architectural calls, product and marketing decisions, naming debates — any decision worth more than one perspective.

Works with Codex, Claude Code, OpenCode, Cursor, ChatGPT Work, and other harnesses that support parallel, isolated subagents.
Inspired by Karpathy's LLM Council.
Claude: /council:council should we rewrite this service in Rust?
Codex: $council:council deep what's the commercial viability of this app right now?
/plugin marketplace add mattakins/council
/plugin install council@mattakins
Plugin skills are namespaced. Invoke this skill as /council:council <question>.
codex plugin marketplace add mattakins/council
codex plugin add council@mattakins
Invoke the plugin skill as $council:council <question>.
npx skills add mattakins/council -g
The Skills CLI installs the shared SKILL.md into the paths expected by the agents you select.
Clone or copy plugins/council/skills/council into one of these supported locations:
- Claude Code:

~/.agents/skills/council/ - OpenCode:
~/.agents/skills/council/or~/.config/opencode/skills/council/
| Command | What it does |
|---|---|
<council> <question> |
Default: 5 agents + Chairman |
<council> 3 <question> |
Use 3 agents |
<council> 7 <question> |
Use 7 agents |
<council> deep <question> |
Research + 7 agents + Chairman (full treatment) |
<council> research <question> |
Explicitly enable research |
<council> no research <question> |
Skip research, reasoning only |
<council> "SEO, legal, UX" <question> |
Specify perspectives explicitly |
<council> quick <question> |
Skip Chairman, faster output |
<council> no chairman <question> |
Same as quick |
<council> save <question> |
Write output to council-YYYY-MM-DD-<slug>.md |
<council> opus <question> |
Run all advisors on Opus (any named model works if your harness supports per-subagent overrides) |
<council> sonnet <question> |
Run all advisors on Sonnet |
Replace <council> with /council:council for the Claude plugin or $council:council for the Codex plugin. Flags combine, and options also work as plain language — e.g. use 4 advisors, no research, and save: <question>.
- Parse — extracts agent count, perspectives, flags, and auto-detects if research is needed
- Research detection — if the question involves markets, companies, current events, or real-world data, agents are automatically told to research before answering. No flag needed.
- Parallel agents — all advisors run simultaneously, blind to each other, each from their assigned perspective
- Chairman synthesis — a fresh, isolated subagent synthesizes the council into a definitive verdict (skippable with
quick) - My Take — the final section: an opinionated recommendation drawing on both the council outputs and full conversation context
Chairman's Verdict:
[Definitive synthesis]
| Agent | Perspective | Recommendation | Confidence |
| ... | ... | ... | ... |
Consensus: ...
Dissent (if any): ...
Risks: ...
Verdict: ...
My Take: ... ← always present, always opinionated

| Tool | Works? | Install path |
|---|---|---|
| Claude Code | ✅ | Plugin or ~/.claude/skills/council/ |
| OpenAI Codex | ✅ | Plugin or ~/.agents/skills/council/ |
| OpenCode | ✅ | ~/.agents/skills/council/ or native OpenCode path |
| Cursor | ✅ | Agent Skills install ( npx skills add ) |
| Other harnesses | Conditional | Requires parallel subagent support |
The instruction format follows the open Agent Skills specification. Full behavior requires a harness that can launch parallel, isolated subagents.
