At a glance

Drafts a pull request body from the session's paper trail: a one-line claim with the smallest proving visual, verify evidence, a reversibility note and glossary terms.

  • Opening a pull request once the work has been verified
  • SKILL.md covers Template, Sections, Triggers and Output
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Updating a PR description after a material change

What it does

This skill assembles the PR body that a reviewer outside the session will read, using only material already established earlier. The Summary states the change in one sentence and adds the smallest fitting visual: pseudocode for logic, a call tree for control flow, a component tree for UI, a shallow file tree for refactors, a Mermaid diagram for data flow, or a diff shaped like the change.

The Evidence section reuses output from the verify protocol (build, test, lint and functionality checks) as before and after pairs, prefers a screenshot for visual changes, and never re-collects or invents evidence. The Reversibility section runs the diff through three ADR questions: hard to reverse, surprising without context, a real trade-off. It then names the rollback method and ends with the blast radius. The result is a paste-ready body plus pointers to the evidence, ADRs and spec it relies on.

When your agent uses it

  • Opening a pull request once the work has been verified
  • Updating a PR description after a material change
  • Writing a PR description that explains how to roll the change back

Example prompts

  • “Draft the PR body for the checkout refactor using the verify results.”
  • “Write a PR description with a component tree for the new settings page.”
  • “Add a reversibility section saying whether reverting the merge is enough to undo this change.”

Requirements

  • Verify-protocol output (build, test and lint evidence) from the session
  • A CONTEXT.md glossary (optional)

What it can do on your machine

Read from SKILL.md and the folder at commit 454bae0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

PR Body Drafter loads about 773 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 373 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~773

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Draft a PR body from OMC's paper trail — the smallest visual that proves the change, evidence consumed from the verify protocol (never re-collected), reversibility from the ADR test on the diff, glossary language throughout.

PR Body

When work lands behind a review, the PR body is the one artifact a reviewer outside the session reads. Everything it needs already exists in the paper trail — this skill assembles it and adds nothing that was not already established. The summary-visual discipline is inspired by show-me (credited in the frontmatter).

Template

markdown
## Summary
<one-line claim, then the smallest visual that proves it>

## Evidence
- **Before:** <output / failing check>
  **After:** <output / passing check>

## Reversibility
<Rollback: cheap via <mechanism> | expensive because <reason>>
<Blast radius: one line>

Sections

Summary

State the change in one sentence, then show the smallest view that makes the point. Match the visual to the change:

  • logic or an algorithm → pseudocode
  • runtime control flow → a call tree
  • UI structure → a component tree
  • file responsibility or a broad refactor → a shallow file tree
  • component interaction or data flow → a Mermaid diagram
  • the delta itself → a diff shaped like the change (component, layout, call tree, or state machine)

Show the whole block only when most of it is new, omitted context would hide ownership, or the reviewer needs a copyable target shape. One visual usually suffices; never all forms.

Evidence

Consume the verify protocol's output — BUILD, TEST, LINT, FUNCTIONALITY evidence, freshness rule inherited. Present before/after pairs: the exact check that failed before and passes after, quoted from the output itself. When the change is visual, prefer a captured screenshot; qa-tester can drive the runtime for one. Never re-collect evidence here and never claim evidence the verify pass did not produce.

Show full SKILL.md (154 more words)Show less
Reversibility

Run the ADR test on the diff itself — the same three questions launch applies to decisions: hard to reverse? surprising without context? the result of a real trade-off? A no on all three is a cheap rollback: say by what mechanism (revert the merge, toggle the flag). Any yes means an expensive rollback: say why. Link the ADR when the change implements or touches one. Close with the blast radius in one line — what else this change can move.

Language

Terms come from CONTEXT.md where a glossary exists. The PR is read outside the session; the glossary is the only vocabulary the reader shares with it.

Triggers

  • launch Phase 5, when the platform reviews through PRs: the completion report carries a PR body drafted by this skill.
  • Any session that opens or materially updates a PR.

Output

  • The PR body, ready to paste
  • The paper-trail pointers it relies on (verify evidence, ADRs, spec)
