plan-runner

A workflow guide for completing one assigned PlanWeave coding task within a defined scope, including reading the task brief, changing the relevant files, running checks, and reporting the result.

In plain words
What is it for?
Use it when a coordinator hands over a specific coding block with file boundaries, expected results, and validation commands.
Why use it?
It helps an implementation agent stay focused on its assigned work without taking over planning or unrelated repairs.

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

plan-runner 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 2d 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 — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan Runner

Use this skill after the coordinator assigns one implementation block. Focus on completing that block precisely; do not schedule, discover, repair PlanWeave state, or reconcile the Plan Package.

Required Packet

The handoff should include:

  • assigned block ref.
  • rendered prompt or prompt path.
  • claim ownership: usually already claimed.
  • scope boundaries and files not to touch.
  • expected report/result artifact.
  • validation commands or observable completion criteria.

If any required item is missing, ask the coordinator for it instead of claiming other work.

Execution Loop

  1. Confirm the assigned ref is implementation work.
  2. If ownership is already claimed, do not run claim or claim-next.
  3. If ownership is claim required, claim only the exact assigned ref/task and stop if a different ref is returned.
  4. Read the rendered prompt and referenced files.
  5. Search nearby producers, consumers, schemas, tests, fixtures, and docs that affect this block.
  6. Make the smallest scoped change that satisfies the prompt.
  7. Run the assigned or directly relevant validation.
  8. Write the requested report and return it, or submit only if the coordinator explicitly asked you to submit.

Quality Gate

  • Do not treat mock, dry-run, fixture-only tests, or uncalled APIs as live completion unless the prompt explicitly scopes the block that way.
  • Keep schema/type/API/CLI/file/prompt contracts aligned between producers and consumers.
  • Preserve unrelated files and behavior.
  • If the prompt is empty, contradictory, stale, blocked, diverged, or points at missing source files, stop and return NEEDS_COORDINATOR.
  • If the assigned block cannot be completed because the plan has bad dependencies, missing prompts, invalid acceptance, wrong review gate design, or stale task scope, stop and return NEEDS_COORDINATOR with the exact plan defect.

Report

Include:

  • assigned ref.
  • changed files.
  • behavior changed and behavior kept.
  • validation run and result.
  • remaining risks or none.
  • any coordinator/recovery issue.

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.

plan-runner is a skill published in the GitHub repository GaosCode/PlanWeave (364 stars, last pushed 4d ago), licensed MIT. It adds 42 tokens to every session and 584 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
