pr-describe

pr-describe is a skill for Claude Code from oguzsh/claudey. It costs 50 tokens per session (620 once invoked), scanned A, original, MIT.

A tool that turns the current Git branch's commits and code changes into a structured pull request description. A pull request is a proposed set of changes for review before merging into a shared codebase.

In plain words
What is it for?
Use it to summarize what changed, why it changed, and the relevant implementation details after comparing the branch with its base branch.
Why use it?
It saves you from reconstructing the purpose and details of a change by hand from commit history and a code comparison.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pr-describe scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

PR Description Generator

Generate a comprehensive, structured pull request description by analyzing the current branch's git history and diff against the base branch.

Workflow

Step 1: Detect base branch and gather changes

  1. Determine the base branch. Default to main unless the user specifies otherwise.
  2. Run these git commands to gather all changes on the current branch:
# Get current branch name
git rev-parse --abbrev-ref HEAD

# Get commit log since diverging from base
git log main...HEAD --oneline --no-merges

# Get full diff against base
git diff main...HEAD
  1. If the diff is very large, also run git diff main...HEAD --stat for a file-level summary to help with the high-level overview.

Step 2: Analyze changes and generate description

Analyze all commits and the full diff to populate each section of the template below. Be thorough - read the actual code changes, not just commit messages.

Guidelines for each section:

  • What? - Concise summary of what the PR does. Use bullet points for multiple changes. Focus on observable behavior changes and new capabilities.
  • Why? - Explain the motivation. What problem does this solve? What ticket or initiative does it relate to? Infer from branch name, commit messages, and code context.
  • Architecture - Include a mermaid diagram ONLY when changes involve architectural patterns: new modules, service layers, API routes, data flow changes, new abstractions, or significant structural reorganization. Skip this section entirely for simple bug fixes, config changes, or minor updates.
  • How it works? - Explain the implementation approach. Walk through the key changes and how they connect. Mention important design decisions.
  • How can I test the branch? - Provide concrete, actionable test steps. Include specific commands to run tests, endpoints to hit, or scenarios to verify. Reference specific test files if tests were added/modified.

Step 3: Output the description

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
