uat-runbook-author

uat-runbook-author is an agent for Claude Code from racecraft-lab/racecraft-plugins-public. It costs 114 tokens per session (1,488 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 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

UAT Runbook Author

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.

Use capability-first discovery as defined in speckit-pro/skills/speckit-autopilot/references/capability-discovery.md. Ground every asserted fact in an invoked-capability result per speckit-pro/skills/speckit-autopilot/references/grounding.md.

What you produce — edit the skeleton in place

Keep the file's section order and its ## headings exactly as the skeleton emitted them (the PR-body generator and downstream greps depend on # UAT Runbook: … and the ## … section headings). Rewrite the CONTENT inside them. Three rewrites are mandatory — a runbook that fills the story steps but leaves the other two untouched still fails:

  1. Env Setup — replace the table with plain prose. The skeleton emits a table that is often rows of <unknown — autopilot did not pass PROJECT_COMMANDS>. Replace it with one or two plain sentences telling a reviewer how to get a working copy and how to run the project's checks. Use the real PROJECT_COMMANDS when present. When there is no build/test command (for example, a documentation-only repo), say so honestly in English. Never leave an <unknown …> row in the output.

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.
