council-runtime

council-runtime is a skill for Claude Code from dorukanc/harness-council. It costs 61 tokens per session (814 once invoked), scanned A, original, MIT.

A guide for coordinating several coding agents, including Grok, AGY, and Claude, through Harness Council, with workers shown in separate cmux tabs.

In plain words
What is it for?
Delegating codebase exploration, coding, testing, planning, and review tasks to other coding agents.
Why use it?
It provides a defined way to divide exploration, implementation, planning, and review between different agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

council-runtime scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Harness Council runtime

You are the orchestrator. Council lets you spawn other coding harnesses as visible cmux workers, pass context between jobs, and collect results. You decide the routing — which harness, model, and mode fits each task. The role table below is the user's recommended defaults, not a hard rule.

Routing precedence

  1. Explicit user instruction in the conversation ("use grok for this").
  2. Project overrides — CLAUDE.md / AGENTS.md guidance and .harness-council.toml role config in the project root.
  3. Recommended defaults below.
Role Harness Mode Use for
explore agy headless (visible log tab) Codebase scout, web research, cheap/light work
code grok interactive (visible TUI) Implementation, refactors, tests, dev tasks
review grok headless read-only Adversarial / second-opinion review
plan claude interactive Peer planner / heavy-model reasoning

Override any of these with harness / model / mode / permission fields on council_spawn (or --harness etc. on the CLI) when the task calls for it.

Prefer MCP tools when configured

If the harness-council MCP server is connected, use:

Tool When
council_spawn Start a worker (role: explore | code | review | plan)
council_wait Block until a job finishes (or poll with council_get_job)
council_get_result Read summary + result after completion
council_list_jobs See running / recent jobs
council_message Nudge a running worker
council_cancel Stop a worker
council_attach Focus the worker's cmux tab
council_setup Readiness check

CLI fallback

council setup
council spawn --role explore "Find all auth entrypoints and summarize"
council spawn --role code --input-job <explore_job_id> "Implement rate limiting based on the exploration summary"
council wait <job_id>
council result <job_id>
council list --status running

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
