PR Description Writer

Read the current branch diff and write a complete GitHub pull request description. Create or update the PR with one command.

Writing Style

Apply to all generated PR descriptions:

• Active voice. "Adds X" not "X has been added."
• Present tense for summary ("Adds caching layer"), past tense for context ("The old approach caused N requests per render")
• Short sentences, one idea per bullet
• No em dashes — use a comma or period instead
• No filler: "this PR", "this commit", "as per the discussion"
• Specifics beat generalities: "reduces p95 latency from 800ms to 90ms" beats "improves performance"
