COORD-Harness AGENTS.md

COORD-Harness AGENTS.md is an instructions file for Codex, OpenCode from 0marm0/COORD-Harness. It costs 451 tokens per session, scanned A, original, MIT.

Repository instructions for CoordHarness, a local system that coordinates multiple coding agents. They explain how the shared SQLite database records tasks, claims, temporary leases, handoffs, and lifecycle events.

In plain words
What is it for?
Onboarding agents, checking the task board, claiming work, reading limited context, renewing leases, handing off tasks, and completing work only after its proof passes.
Why use it?
They reduce coordination errors by defining one source of truth and clear rules for claiming, completing, pausing, or transferring work.

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

COORD-Harness AGENTS.md 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 3d 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.

What it actually says

CoordHarness agent entrypoint

COORDHARNESS_AGENT_INSTRUCTION_SENTINEL=v1

CoordHarness coordinates multi-agent work through one local SQLite authority. coord.db owns work, claims, leases, handoffs, and lifecycle events. Markdown provides stable orientation only; dashboards, job sidecars, knowledge.db, facts, KFTS, and accepted memory are evidence or recall, never lifecycle state.

Start and finish

  1. Use $operating-coordharness (repo skill: .agents/skills/operating-coordharness/).
  2. Run .venv/bin/coord onboard --register-clients once, then MCP preflight. If the board is empty, use .venv/bin/coord create with a concrete repository-relative done_signal.
  3. Expand with bounded board, next_work, and work_context reads. Use the context lenses only when the active row needs broader history or source evidence.
  4. Claim before substantive work. Renew only near lease expiry or a material milestone.
  5. Complete only after the declared proof passes. Otherwise park, block, release, or use the typed handoff command with exact row fences.

Do not edit SQLite or lifecycle projections by hand. Preserve unrelated dirty work and never weaken identity, proof, review, or authority checks to make a transition pass.

Context hierarchy

  • Clean-room installation and verification: docs/agent-onboarding.md
  • Claims, reviews, events, and handoffs: docs/agent-protocol.md
  • Bounded board and federated retrieval: docs/context-architecture.md
  • Facts, knowledge, and memory boundaries: docs/context-and-memory.md
  • Durable CPU/GPU processes: docs/jobs-and-runs.md
  • Detailed skill references: .agents/skills/operating-coordharness/references/

Read the focused document that answers the current gap; do not load the documentation set or a full board dump by default. Run focused tests for changed surfaces and report exact files, commands, uncertainty, and remaining risk. Do not commit or push unless the user explicitly asks.

Changes

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.
