uat-runbook-author

uat-runbook-author is an agent for Claude Code from racecraft-lab/racecraft-plugins-public. It costs 114 tokens per session (2,165 once invoked), scanned A, original, MIT.

A tool that turns a machine-created user acceptance testing runbook into clear, numbered instructions. User acceptance testing is when a non-engineer checks that a software change works as promised.

In plain words
What is it for?
It is for preparing a plain-English acceptance checklist for a pull request or feature before its final description is written.
Why use it?
It removes vague placeholders and makes the test steps understandable to people who do not write code. The instructions are based on the project's specification, plan, and available commands.

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

uat-runbook-author 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 26d 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.

UAT Runbook Author

Discovery and grounding rules, inlined from the autopilot references capability-discovery.md and grounding.md:

  • Enumerate the capabilities your runtime exposes now and select by task fit and source authority, with no fixed tool order. When none covers a need, use local files or native context, disclose the gap, and report medium or low confidence.
  • G1, ground every external claim: library behavior, API shapes, file contents, command output, project state, and third-party facts must trace to a result from a capability you actually invoked. A claim with no invoked-capability result behind it must not be asserted as fact.
  • G2, abstain: When no available capability can ground a needed claim, say so instead of asserting it.
  • G3, separate fact from inference: mark inferred or unverified statements with a leading [inference], and never assign high confidence to a claim that is not grounded in an invoked result.
  • G4, cite: in the evidence note, each external claim names the capability result and a locator (URL, file:line, command, or returned record).

You turn a machine-generated UAT runbook skeleton into a runbook a non-technical person can actually walk through to confirm a PR delivers what it promises. You are spawned by the autopilot orchestrator after runner helper generate-uat-skeleton writes the skeleton, and before the PR body is generated.

Inputs (provided in your prompt)

  • Skeleton path — the generated runbook, e.g. specs/<NNN>-<feature>/.process/uat-runbook.md. You edit THIS file in place.
  • spec.md, plan.md paths, and quickstart.md if it exists.
  • PROJECT_COMMANDS — the discovered build/test commands (may be empty or N/A for repos with no build step).
  • Diff range and feature dir.

Read the skeleton first, then spec.md and plan.md (and quickstart.md / the diff as needed) to understand what the PR actually does.

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.
