Prbuddy

prbuddy

Overview

prbuddy helps agents monitor PR health by checking CI status and triaging review comments. It fixes immediate issues and implements systematic prevention measures.

Philosophy: "Fix the acute issue AND prevent the class of error from recurring."

Sub-skills:

• prbuddy:ci - CI/workflow monitoring, failure diagnosis, fix + prevent
• prbuddy:reviews - Review comment triage, fix critical, create issues for nitpicks

Prerequisites

Required: gh CLI

Verify gh is installed and authenticated:

gh auth status

If not authenticated, run gh auth login.

Required token scopes:

• repo - Full control of private repositories (for PR operations)
• read:org - Read org membership (for issue creation in org repos)
• workflow - Update GitHub Action workflows (for CI operations)

To check scopes: gh auth status shows granted scopes.

Required: gh-pr-review Extension

This extension is required for review comment handling:

gh extension install agynio/gh-pr-review

Verify installation:

gh pr-review --help

When This Skill Applies

• "check my PR" / "PR status"
• "make this PR green"
• "fix my PR"
• "ready to merge"
• "handle PR feedback"
• "what's blocking my PR"

Workflow

Step 1: Detect PR

gh pr view --json number,title,body,url,headRefName,closingIssuesReferences

If no PR found for current branch, ask user:

• Create a PR: gh pr create
• Specify PR number: /prbuddy 123
• Specify PR URL

Step 2: Check CI Status

gh pr checks --json name,state,bucket,link

If any checks failed: Route to prbuddy:ci

If checks pending: Report status and suggest checkpoint timing:

• "CI is still running. Check again before requesting review or declaring done."

If all checks passed: Continue to reviews

Step 3: Check Review Comments

Route to prbuddy:reviews

Step 4: Report Summary

PR #42 Health Check Complete

CI: ✓ All checks passing
Reviews:
  - 2 critical comments fixed (with prevention)
  - 3 issues created from nitpicks

Ready for: [next action - request review / merge / etc.]

Routing Logic

Keywords → Sub-Skill

prbuddy:ci:

• "CI failing", "workflow failed", "checks red"
• "build broken", "tests failing"
• "check CI status", "rerun workflows"

prbuddy:reviews:

• "review comments", "address feedback"
• "reviewer asked", "changes requested"
• "handle comments", "triage reviews"

prbuddy (full orchestrator):

• "check my PR", "PR health", "make PR green"
• "fix PR", "ready to merge"
• Ambiguous requests

Routing Process

1. Analyze request for keywords
2. If clearly CI-related → prbuddy:ci
3. If clearly reviews-related → prbuddy:reviews
4. Otherwise → Run full orchestrator (CI then reviews)

Error Handling

No PR Found

No PR found for current branch 'feature-xyz'.

Options:
1. Create a PR: gh pr create
2. Specify PR number: /prbuddy 123
3. Specify PR URL: /prbuddy https://github.com/owner/repo/pull/123

gh-pr-review Extension Missing

Fork-Based PRs

This skill assumes write access to the PR branch. For fork-based PRs:

• You may not have push access to the source branch
• Protected branch rules may prevent direct pushes
• Consider creating a fix branch and opening a separate PR

Workaround: Ask the user to push changes manually or grant write access.

Dry-Run Mode

To preview changes without committing, tell the agent:

• "Show me what you would fix, but don't commit"
• "Dry-run mode" or "preview only"

The agent will analyze and report proposed fixes without making changes.
