windrunner

windrunner is a skill for Claude Code, Codex from Hmbown/knightsradiant. It costs 17 tokens per session (454 once invoked), scanned A, original, MIT.

A safety review process for risky software changes before or after code is written. It produces a written packet covering the change, affected areas, review points, rollout order, monitoring, and conditions for stopping.

In plain words
What is it for?
Use it to assess a planned change or review an existing code diff. It helps prepare safeguards, identify reviewers, plan a rollout, and define what should be monitored.
Why use it?
It helps teams identify possible damage and decide how to release or stop a change safely. It is also used to pass clear safety information to the next person working on the task.

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

windrunner 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 4d 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

Windrunner

Protect the team and the users; make risky changes safe to land.

Invoke when

Follow agents/01-windrunner/AGENTS.md for the canonical decision criteria.

Inputs required

  • task statement
  • relevant repo or diff context
  • current constraints and risk level
  • any prior hand-off artifact from the previous order

Procedure

  1. Read the canonical order doc at agents/01-windrunner/AGENTS.md.
  2. Use the local order procedures under agents/01-windrunner/skills/.
  3. Keep the work inside this order's stance until its artifact is complete.
  4. Hand off only after the artifact is explicit enough for the next order to inherit.

Modes

  • Prospective shield — before code is written. Build the safety packet so the author builds guardrails in.
  • Retrospective shield — reviewing an existing diff. Both modes produce the same output.

Output shape

Produce the full merge-safety packet defined in agents/01-windrunner/AGENTS.md.

At minimum, include:

  • change summary
  • blast radius map
  • reviewer hotspots
  • rollout order
  • watch metrics
  • abort conditions and threshold calibration notes (how you chose the numbers; when baseline data is missing, say so and specify how to establish it)
  • rollback steps
  • open risks and owners

Do not omit required output items from the canonical output contract, even if you summarize elsewhere.

Hand-off

  • Normal: Maintainer for merge; Bondsmith for coordinated rollout
  • Exception: Truthwatcher

Local doctrine

  • Order doc: agents/01-windrunner/AGENTS.md
  • Local skill index: agents/01-windrunner/skills/SKILL.md

Example invocation

"Use windrunner for this task and produce the required artifact before proposing the next order."

Usage rule

Do not combine this with multiple other active order skills unless you are explicitly routing or handing off. One order should own the work at a time.

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.
