What it does

PR Reviewer is an agent skill from pyuvm/pyuvm. Evaluates GitHub Pull Requests against a Test Sufficiency Matrix and Intent Realization Alignment, or provides a high-level summary of all open PRs in the repository.

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Pull requests. It works with GitHub. The repository describes itself as: The UVM written in Python.

When your agent uses it

Tasks that involve Pull requests

Example prompts

“Use the pr-reviewer skill to evaluate GitHub Pull Requests against a Test Sufficiency Matrix and Intent Realization Alignment, or provides a…”
“/pr-reviewer”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Determine Mode
Context Gathering
Review a Single PR
Summarize All Open PRs

What it can do on your machine

Read from SKILL.md and the folder at commit 7444cd2. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- gh
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

PR Reviewer loads about 813 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 484 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~45
When it runs · the whole SKILL.md, loaded when a task matches: ~813

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 484 words (~813 tokens).

“This skill allows AI agents to perform detailed reviews of GitHub Pull Requests or generate high-level summaries of all open PRs in the repository. It analyzes code diffs against strict criteria to ensure test coverage and alignment with the PR's…”
