GitHub Contributor

A phase-based playbook for shipping pull requests that maintainers of third-party repos actually merge.

Dev & CodingIntermediate★ 1,323⑂ 212AI score 9/10Last updated: Aug 8, 2026

What it does

Breaks the PR lifecycle into five phases, each targeting a distinct failure mode:

  • Phase 1 – Discovery: treat CONTRIBUTING.md as a hard contract, benchmark your diff against recently merged PRs with gh pr list, and write a scope contract before coding
  • Phase 2 – Implementation: branch from upstream main, smallest-possible diff, Conventional Commits, --fixup + autosquash workflow
  • Phase 3 – Quality gates: run the project's exact lint/test commands, isolate the data directory before real E2E runs on Tauri/Electron apps, self-audit every "I tested…" claim, verify mergeability before declaring ready
  • Phase 4 – PR description: body skeleton (Summary / Why / Test Plan / Backward Compatibility / Screenshots), test-coverage matrix, AI-assisted disclosure template, screenshot handling without polluting the repo
  • Phase 5 – Post-submission: reply inline to bot reviews via gh api in_reply_to, rebase with --force-with-lease, filter counter-review findings by probability/cost/scenario

Closes with 10 anti-patterns that get PRs shut down and concrete quality metrics (1–5 files, <200 lines of production code, <24h response time).

Who it's for

  • Developers making their first contributions to unfamiliar OSS repos
  • Anyone using AI assistance who needs to disclose it credibly
  • Teams standardizing bot-review responses and rebase hygiene

Examples

  1. "Open a PR upstream for this fix" → parse CONTRIBUTING.md → compare size to merged baseline → minimal commits → PR body with real test evidence
  2. "Respond to the CodeRabbit review" → filter findings, then reply on each line citing the fixing commit and test
  3. "Rebase my branch against main" → fetch, resolve file-by-file, autosquash fixups, push with --force-with-lease so review threads survive

Try it now, no install

Paste this into Claude to use the skill without installing anything.

Read the instructions in this file and follow them to help me:
https://raw.githubusercontent.com/daymade/claude-code-skills/HEAD/github-contributor/SKILL.md

What I want: (describe your task here)

If Claude can't open the link, open it yourself and paste the contents instead.

↓ If it works for you, download the ZIP below and install it. Then it runs on its own — no pasting each time.

Install in the Claude app (no terminal)
  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.
↓ Download ZIP
Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the github-contributor folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/github-contributor/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git /tmp/ccs && mkdir -p ~/.claude/skills && cp -r /tmp/ccs/github-contributor ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and confirm git --version and gh --version work. Install GitHub CLI if needed (brew install gh or your OS package manager) and authenticate with gh auth login.
  2. Clone the repo to a temp folder: git clone https://github.com/daymade/claude-code-skills.git /tmp/ccs
  3. Create your skills directory: mkdir -p ~/.claude/skills
  4. Copy the whole skill folder, including references/: cp -r /tmp/ccs/github-contributor ~/.claude/skills/
  5. Verify with ls ~/.claude/skills/github-contributor — you should see SKILL.md plus a references/ directory.
  6. Restart Claude Code and try a prompt like "submit a PR to owner/repo" to trigger the skill.
