About pr
A coding-agent skill for developers preparing pull requests. It guides concise PR bodies with visuals suited to the change, before-and-after evidence, and an assessment of merge risk.
Key features
- 01Choose a visual format by change type
- 02Use pseudocode, call trees, or Mermaid
- 03Include before-and-after evidence
- 04Assess rollback difficulty and blast radius
Use cases
- 01Draft a PR body for a code change
- 02Illustrate control flow or file structure
- 03Summarize test and screenshot evidence

Details
From the project READMEUse this template for writing the PR body:
## Summary
<diagram, diff-sketch, or tree>
## Evidence
- **Before:** <screenshot/output/failing test run>
**After:** <screenshot/output/passing test run>
## Merge Danger
**Door:** <one-way or two-way>
<optional: description>
**Blast Radius:** <one-word description>
<optional: potential ramifications of merge>
Sections
Skip all preambles and keep prose brief. Use the user's domain language from GLOSSARY.md.
Summary
Pick the smallest view that makes the key point clear.
- Show logic or an algorithm as pseudocode:
on(save)
if content is unchanged
return cached result
write new content
return fresh result
- Show runtime control flow as a call tree:
submitForm
createSession
persistPrompt
launchAgent
navigateToSession
- Show UI structure as a component tree, including state and module boundaries that matter:
<SessionPage> (apps/example/src/routes/session.tsx)
useSessionEvents()
<SessionToolbar>
<RunSkillButton> (packages/ui)
- Show file responsibility or a broad refactor as a shallow file tree:
src/
├── commands/ # parses user actions
├── sessions/ # owns session state
└── transport/ # sends API requests
- Show component interaction, control flow, or data flow with Mermaid:
sequenceDiagram
participant User
participant UI
participant Daemon
User->>UI: choose command
UI->>Daemon: send expanded prompt
Daemon-->>UI: stream result
- Use
diffwhen the point is what changes and the surrounding shape already exists. Match the diff shape to the topic.
For a component change:
<SessionPage>
useSessionEvents()
<SessionToolbar>
+ <RunSkillButton />
<SessionTimeline>
+ <SkillResultCard />
For a file-layout change:
src/
├── commands/
+│ └── show-me.ts # expands the slash command
├── sessions/
-└── transport.ts
+└── transport/
+ ├── client.ts
+ └── stream.ts
For a call-tree or call-stack change:
submitForm
createSession
persistPrompt
+ expandSkillMention
launchAgent
- navigateToSession
+ navigateToSession
+ subscribeToEvents
For a state or control-flow change:
on(save)
- write content
+ if content is unchanged
+ return cached result
+ write new content
+ invalidate cache
- Show the whole block when most of it is new, when omitted context would hide ownership or order, or when the user needs a copyable target shape:
function expandSkill(command: string): string {
const skillName = command.slice(1);
return `use the ${skillName} skill`;
}
Guidance
Place each visual next to the short text it supports. Keep only the calls, files, props, states, and boundaries needed to answer the user's current question or the options to resolve the current discussion point.
You may use one of these, you may use several, it is unlikely you will use all of them. Use your judgement and don't overwhelm the user.
Evidence
Concrete evidence that the change works. Show a before and after.
Screenshots are S-tier - when the environment is set up for it and the change is visual.
Execution-based evidence is A-tier. Test results, console output. Show the exact test that now fails and passes, using pseudocode.
Merge Danger
Describe whether it's a one-way or two-way door. You can walk back through two-way doors, but not one-way doors. A PR that is cheap to roll back is lower risk. Changes that involve destructive actions or hard-to-reverse decisions are one-way doors.
The blast radius is the potential impact or scope of the changes introduced by this PR. Consider all possibilities. Examples are layout shift, breakages for consumers, mobile responsiveness, etc.
