What it does

PR Review is an agent skill from sd0xdev/sd0x-harness. PR self-review — review changes, produce checklist, update rules

Its SKILL.md is about 230 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. The repository describes itself as: The harness layer for Claude Code — a reference implementation of harness engineering with hook-enforced dual review, state-machine gates that survive context compaction, and… The licence is MIT.

When your agent uses it

  • Tasks that involve Pull requests

Example prompts

  • “/pr-review”

Requirements

  • Pre-approved tools (allowed-tools): Bash(git:*), Read, Grep, Glob, Edit

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Run /risk-assess --mode fast — if High+, auto-escalate to deep mode
  2. Review: correctness, security, performance
  3. PR checklist: tests, rollout, compatibility
  4. Discover new rules -> update CLAUDE.md or .claude/rules/

What it can do on your machine

Read from SKILL.md and the folder at commit a4d4bc1. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash(git:*)
    • Read
    • Grep
    • Glob
    • Edit

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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 Review loads about 229 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 63 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~229

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.
