hashiiiii-explain-pr

hashiiiii-explain-pr is a skill for Claude Code from hashiiiii/rules-for-ai. It costs 30 tokens per session (506 once invoked), scanned A, original, MIT.

A read-only guide for explaining a pull request, which is a proposed set of code changes, and its relationship to an issue, a tracked problem or request. It uses the pull request's text, commits, metadata, and complete code diff as evidence.

In plain words
What is it for?
Use it to explain a pull request's purpose, related requirements, changed behavior, and individual changes in a requested language and scope.
Why use it?
It separates observed changes from guesses about intent and makes missing or inaccessible information explicit.

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

hashiiiii-explain-pr 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 yesterday.

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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Explain a pull request

Explain the reviewed diff in the user's requested language and scope. Work read-only.

Gather evidence

  • Read the PR title, body, commits, and complete diff. Record the reviewed base and head revisions.
  • Find related issues in PR metadata and body links, then read them. A related issue is optional.
  • If a source is inaccessible or the diff is incomplete, state the limit and explain the available material.
  • Read surrounding code at those revisions when needed to explain behavior. Check dependency versions when choosing documentation.

Explanation

Background and purpose

Describe the background, problem, and goal in about ten lines. Use fewer lines when the evidence is sparse.

  • With related issues, explain their requirements and how they relate to the PR's stated purpose.
  • Without related issues, use the PR body, commit messages, and implementation before and after the change.
  • Cite the sources for the stated purpose. Label inferred motivations as inferences and missing information as unknown.

Changes by meaning

Give each independent changed statement, setting, condition, or test case its own entry. Keep a single expression spanning several lines together. Split function bodies into independent statements and branches. For example, three added test cases require three entries. Cover every change within the requested scope, including tests and documentation. Group repeated equivalent edits and list their affected locations.

For each entry, use these fields:

  • Location: file path, line numbers, and a short excerpt of the changed lines. Link to the reviewed revision.
  • Behavior: explain what the syntax means and what changes before and after the PR.
  • Purpose: explain its contribution to the PR's goal. With related issues, identify the corresponding requirement and link it.
  • References: link official documentation beside the syntax or behavior it supports.

Use base-revision locations for removed code and head-revision locations for added code. Say when a unit has no established relationship to the stated purpose or leaves a requirement unmet.

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.
