Agent Council

Five reviewers pull your draft apart, keep their disagreement visible, and hand you one verdict — for the text you can't un-ship.

A runtime-portable 5-agent council that adjudicates text artifacts before they ship. Five role-conditioned LLM deliberators run in a 2-round async protocol with cross-read rebuttal. One verdict — SHIP, REVISE, or HOLD — plus a structured revision brief and a full audit transcript.

No SDK. No API keys. No vendor lock-in. The Council shells out to whatever LLM CLI is configured (claude, lmstudio, ollama, mock). Modularity invariant is CI-tested — the council can be removed and producing agents keep working unchanged.

Install

Claude Code (plugin)

claude plugin marketplace add Avyayalaya/agent-council
claude plugin install agent-council@avyayalaya

Then in any Claude Code session: /council-review path/to/artifact.md or /council-sweep.

Python (pip from source)

git clone https://github.com/Avyayalaya/agent-council.git
cd agent-council
pip install -e .
cp council.yaml.example council.yaml  # then edit
python -m agent_council review path/to/artifact.md --tier=1

Requires Python ≥3.11 and at least one supported LLM CLI on PATH.

MCP server (Claude Desktop, Cursor, Cline, custom agents)

pip install mcp>=1.0

Add to your client's MCP config:

{
  "mcpServers": {
    "agent-council": {
      "command": "python",
      "args": ["<absolute-path>/agent-council/mcp/agent_council_mcp_server.py"],
      "env": {
        "COUNCIL_CONFIG": "<absolute-path>/agent-council/council.yaml"
      }
    }
  }
}

Tool exposed: council_review(artifact_path, tier=1). Full setup: mcp/README.md. council_sweep and council_audit tools land in v0.1.2.

the analytics product CLI, Cursor, Cline, OpenCode (via APM Skills)

v0.1.1 ships each deliberator as a standalone Skill under skills/ so any APM-compatible harness gets the methodology inline — no Python CLI required for single-perspective review.

apm marketplace add Avyayalaya/agent-council
apm install agent-council --target copilot

Then in the harness, load one Skill at a time:

• skeptic-review — adversarial steelman pass
• voice-identity-review — line-level voice audit + CXO test
• evidence-calibration-review — per-claim T1-T6 evidence-tier audit
• strategy-stakes-review — goal-fit and opportunity-cost check
• adjudicator-synthesis — verdict synthesis from 2+ deliberator outputs

Use cases per surface:

| Use case | Surface | |---|---| | Run full automated Council on an artifact with parallel deliberators + 2-round cross-read + JSONL audit | python -m agent_council review path/to/artifact.md --tier=1 or MCP council_review tool | | Apply one deliberator role to a doc I am editing right now (the analytics product, Claude, Cursor) | Load the matching Skill | | Compose 2 or 3 deliberators ad-hoc for a multi-angle ad-hoc review | Load multiple Skills sequentially, then optionally load adjudicator-synthesis | | Use slash commands in Claude Code | /council-review path/to/artifact.md (Claude Code only) |

Skills vs CLI — what you get on each path

The Skills are the interactive single-perspective surface. The CLI / MCP is the automated full-Council surface. They share the same 5-deliberator methodology but trade differently:

| Capability | Compose Skills sequentially | Full Council via CLI / MCP | |---|:---:|:---:| | One perspective at a time | yes | yes (the deliberators) | | Parallel deliberator execution | no | yes | | Round 2 cross-read rebuttal (each deliberator sees the other 3 R1 critiques) | no | yes | | Adjudicator prior-verdict compounding loop on artifact_type | no | yes | | JSONL audit log, replayable | no | yes | | Single adjudicated verdict (not 5 separate critiques) | no | yes | | Structured, persisted verdict record per run | no | yes | | Cost per review | 1 LLM call per Skill | ~9 LLM calls (4 deliberators × 2 rounds + Adjudicator) | | Sweet spot | Ad-hoc 1 or 2 perspectives on a doc you are editing | Pre-ship gating in pipelines; structured, persisted audit trail |

Composing 5 Skills sequentially produces 5 independent critiques. That is useful for ad-hoc multi-angle review, but it is not the same artifact as the automated Council. If you need parallel execution, cross-read rebuttal, or a structured, persisted JSONL verdict record, use the CLI / MCP path.

Any other LLM (ChatGPT, Gemini, manual)

Read the 5 prompts at prompts/. Each is self-contained and explains what the deliberator should produce. Run them in your tool of choice, then merge the verdicts using the policy in src/agent_council/verdict.py.

The five roles

| Deliberator | Concern | Reads | |---|---|---| | Skeptic | Adversarial review — catches premature coherence, narrative fallacy, survivorship bias, unstated assumptions | (artifact only) | | Voice & Identity | Voice DNA, banned-pattern enforcement, channel register, CXO test | Operator's voice corpus + persona DNA | | Evidence & Calibration | Source verification, evidence-tier classification (T1–T6), confidence levels, base rates | (artifact only) | | Strategy & Stakes | Goal alignment, stake calibration, opportunity cost vs. operator's active projects | Operator's goals doc + project state | | Adjudicator | Merge + prior-verdict loop. Final verdict and revision brief | All four above + council_log.jsonl |

Why a council, not a single judge?

LLM-as-judge approaches collapse five distinct concerns into one critic:

• Is the argument adversarially sound?
• Does it match the operator's voice?
• Are the sources credible?
• Does it advance the operator's actual goals?
• Should it ship?

A unified judge averages these into one score. The Council keeps them separated. Each deliberator owns one concern, reads one context, surfaces one kind of dissent. The Adjudicator merges them — but you see which deliberator blocked and why, not just the merged number.

This matters for tier-1 artifacts where the cost of shipping a flaw is high (public publish, irreversible commitment, identity-shaping document) and the cost of one more revision pass is low.

Quickstart

After pip install -e . and copying council.yaml.example → council.yaml:

# Single artifact
python -m agent_council review path/to/artifact.md --tier=1

# Daily sweep over watch paths
python -m agent_council sweep --since=24h

# Audit recent verdicts (filter by date/verdict/artifact-type)
python -m agent_council audit --since=7d --verdict=HOLD

Output goes to stdout as JSON; the audit row appends to council_log.jsonl.

See what a verdict looks like

examples/demo/ ships a fictional LinkedIn post + the structured verdict the Council produced for it + the extracted revision brief. Read these first to calibrate expectations before running your first real review.

Tier classification

The Council is designed for tier-1 artifacts — the ones where review cost is justified:

• Tier 1 (gates through Council): external-facing OR irreversible OR identity-shaping OR memory writes. Examples: published writing, public READMEs, investor messages, resume revisions, additions to a learnings file, memory writes.
• Tier 2 (skips Council): internal drafts, dashboards, infrastructure, dispatch updates.
• Tier 3 (1-in-5 sample): daily briefings, internal analyses, planning artifacts.

Tier classification is rule-based — glob patterns in council.yaml#tier_rules.

---

Built for agents

The Council was designed to be invoked from outside an agent loop, not from inside it. That's not a stylistic choice — it's a CI-tested invariant:

PYTHONPATH=src python -m unittest tests.test_modularity_invariant -v

The test scans the host operator system's agents/*/prompt.md files and asserts zero references to Council. If a producing agent's prompt starts to know about the gate that reviews it, the build fails.

This means:

• An orchestrator can route any artifact to Council without touching the producing agent.
• Removing the Council leaves every producing agent functional (with reduced quality on tier-1 artifacts).
• The Council ships as a standalone runtime — wire it into Emissary, MCP servers, slash commands, CI pipelines, or your own agent system without coupling.

AGENTS.md is the machine-readable capability manifest — agent orchestrators read this to route tasks without reading 1,300 lines of source.

Add a new runtime adapter (one file)
