claude-fix-pr

Fix PR issues (review comments, test failures, missing docs) using Claude Code. Works as both a local CLI plugin and a reusable GitHub Action.

Installation

As a Claude Code Plugin (local development)

claude plugin install deployhq/claude-fix-pr

Then in any repo with a PR:

/fix-pr           # fixes current branch's PR
/fix-pr 123       # fixes PR #123

As a GitHub Action (CI automation)

Add .github/workflows/fix-pr.yml to your repo:

name: Fix PR
on:
  check_suite:
    types: [completed]
  issue_comment:
    types: [created]

jobs:
  fix-pr:
    uses: deployhq/claude-fix-pr/.github/workflows/fix-pr.yml@main
    secrets:
      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}

That's it. The action will:

• Auto-trigger when CI fails on a PR branch
• Manual trigger when someone comments /fix-pr on a PR
• Skip protected branches (main, master, staging)

How It Works

flowchart TD
    A["/fix-pr comment on PR"] --> B["React with eyes emoji"]
    C["CI fails on PR branch"] --> D{Protected branch?}
    B --> D

    D -- Yes --> E["Skip — refuse to modify"]
    D -- No --> F["Gather PR context via gh CLI"]

    F --> G["Review comments"]
    F --> H["CI failure logs"]
    F --> I["Documentation feedback"]
    F --> J["PR diff"]

    G & H & I & J --> K["Fill prompt template"]
    K --> L["Run Claude Code with scoped tools"]
    L --> M{Changes made?}

    M -- Yes --> N["Reply to each addressed comment"]
    N --> O["Commit & push fixes"]
    O --> Q["Post summary comment on PR"]
    M -- No --> P["Comment: no issues found"]

Steps

1. Gathers context — review comments (with IDs), CI failures, documentation feedback, and PR diff using gh CLI
2. Builds a prompt — fills a shared template with all gathered context
3. Runs Claude — Claude reads the context, makes targeted fixes, and replies to each addressed comment via gh api
4. Reports back — commits changes and posts a summary comment on the PR

What It Does

• Fixes review comments — reads inline code review feedback and conversation comments, applies fixes
• Fixes CI failures — analyzes test failures, linting errors, type check issues
• Fixes documentation — typos, missing docs, outdated comments
• Replies to comments — replies to each addressed review comment with a brief description of the fix

Safety

• Only modifies files in the PR's diff
• Refuses to run on protected branches (main, master, staging)
• Tool access is scoped — Claude can only read, edit, run tests/linters, and reply to PR comments
• In local mode, asks for confirmation before committing
• In CI mode, commits are attributed to claude-fix-pr[bot]

Requirements

• GitHub CLI (gh) — authenticated
• Claude Code CLI — for local plugin use
• ANTHROPIC_API_KEY — set as environment variable (local) or GitHub secret (CI)

Repository Structure

.claude-plugin/plugin.json    — Plugin metadata
commands/fix-pr.md            — Local /fix-pr slash command
agents/pr-fixer.md            — Subagent for complex fixes
scripts/gather-pr-context.sh  — Context gathering (shared by CLI and CI)
prompt-template.md            — Prompt template (shared by CLI and CI)
.github/workflows/fix-pr.yml  — Reusable GitHub Action workflow

Configuration

Customizing triggers (GitHub Action)

The reusable workflow responds to check_suite (auto) and issue_comment (manual). To limit triggers, override in your calling workflow:

on:
  issue_comment:
    types: [created]   # manual only — no auto-trigger on CI failure

jobs:
  fix-pr:
    uses: deployhq/claude-fix-pr/.github/workflows/fix-pr.yml@main
    secrets:
      ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}

Adding custom test commands

The workflow allows Claude to run common test commands (bin/rspec, rubocop, go test, yarn test, npm test). To add more, fork the workflow and extend the --allowedTools list.
