What it does
Mz PR Review is an agent skill from MaterializeInc/materialize. Local code review of current branch vs Materialize standards. Trigger: "review my code", "review my changes", "check my diff", "does this look ok", "what do you think of this PR", "code review", or look over changes before merging. Also PR number + wants feedback on quality, style, correctness.
Its SKILL.md is about 1.6k 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, Code review and SQL. It works with SQL, Rust, Git and PostgreSQL. The repository describes itself as: The live data layer for apps and AI agents. Create up-to-the-second views into your business, just using SQL.
When your agent uses it
- Tasks that involve Pull requests
- Tasks that involve Code review
- Tasks that involve SQL
Example prompts
- “review my code”
- “review my changes”
- “check my diff”
- “/mz-pr-review”
Requirements
- Pre-approved tools (allowed-tools): Bash, Read, Grep, Glob, Task
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Parse arguments from: $ARGUMENTS — a PR number, base branch, or nothing.
- Get the diff using the first method that works
- Get the file list from the same diff (add --stat for git, --stat for jj, or gh pr diff 123 --stat for PR).
- Review the diff against the checklists below.
- Present findings organized as: Blocking, Strong suggestions, Nits.
What it can do on your machine
Read from SKILL.md and the folder at commit 6515d14. 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:
BashReadGrepGlobTask
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
ghgitcargo
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
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
Mz PR Review loads about 1.6k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 748 words of instructions outside code blocks.
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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Bash, Read, Grep, Glob, Task
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 748 words (~1,617 tokens).
“Perform a local code review of the current branch's changes against Materialize project standards.”
