pr-description

A tool for drafting a pull request description from the commits and code changes on the current Git branch. A pull request is a request to review and merge changes into a shared branch.

In plain words
What is it for?
Finding the default branch, comparing the current branch with it, reviewing the commits and file changes, and producing a formatted pull request description.
Why use it?
It removes the need to reconstruct the change summary manually and can use an existing pull-request template.

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-description 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 2d 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.

The opening of the file, as written. The whole thing — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Generate PR Description

Analyze the current branch's commits and diffs against the default branch, optionally use a PR template, and output a well-formatted PR description.

Step 1: Determine the default branch

Try to find the default branch name:

git rev-parse --verify main >/dev/null 2>&1

If main exists, set DEFAULT_BRANCH=main.

Otherwise, try master:

git rev-parse --verify master >/dev/null 2>&1

If master exists, set DEFAULT_BRANCH=master.

If neither exists, try to detect via the remote HEAD:

git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's|refs/remotes/origin/||'

If this returns a branch name, use that as DEFAULT_BRANCH.

If no default branch can be determined, report "❌ Could not determine the default branch (tried main, master, and origin HEAD)" and stop.

Step 2: Gather commits and diffs

Run the following commands to collect change information:

  1. Full commit log with diffs (for deep analysis):

    git log $DEFAULT_BRANCH..HEAD -p --reverse
    
  2. File change summary (for the overview):

    git diff $DEFAULT_BRANCH..HEAD --stat
    
  3. One-line commit list (for reference):

    git log $DEFAULT_BRANCH..HEAD --format="%h %s"
    

If no commits are found between $DEFAULT_BRANCH and HEAD (i.e., the output is empty), report "❌ No commits found between $DEFAULT_BRANCH and HEAD. Make sure you are on a feature branch with commits ahead of $DEFAULT_BRANCH." and stop.

Step 3: Search for a PR template

Check for a PR template in these locations, in priority order, using the Glob tool:

  1. .github/PULL_REQUEST_TEMPLATE.md
  2. .github/pull_request_template.md
  3. PULL_REQUEST_TEMPLATE.md (repo root)
  4. pull_request_template.md (repo root)
  5. docs/PULL_REQUEST_TEMPLATE.md
  6. docs/pull_request_template.md
  7. .github/PULL_REQUEST_TEMPLATE/ directory (if it exists, list all .md files inside and use the first one)

Use glob patterns like **/{PULL_REQUEST_TEMPLATE,pull_request_template}.md to search efficiently.

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.

pr-description is a skill published in the GitHub repository surajssd/dotfiles (5 stars, last pushed 4d ago), licensed MIT. It adds 53 tokens to every session and 1,396 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
