What it does

Code Review is an agent skill from razorpay/blade. Guidelines for reviewing Blade PRs — sanity checks, code quality, API decisions, usecase validity, and UI review.

Its SKILL.md is about 260 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/api-decision-critique.md`, `references/code-quality-critique.md` and `references/output-format.md`).

It sits in Development, covering Code review and Code quality. The repository describes itself as: Design System that powers Razorpay. The licence is MIT.

When your agent uses it

  • Tasks that involve Code review
  • Tasks that involve Code quality

Example prompts

  • “Use the code-review skill to guideline for reviewing Blade PRs — sanity checks, code quality, API decisions, usecase validity, and UI review”
  • “/code-review”

What it can do on your machine

Read from SKILL.md and the folder at commit e65bdec. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Code Review loads about 260 tokens when it runs, and up to ~2.7k if it reads all its reference files. Until then it costs about 31 tokens; SKILL.md has 112 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~31
When it runs · the whole SKILL.md, loaded when a task matches
~260
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.7k

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.

Blade PR Code Review Guidelines

Use these guidelines to review a Blade PR. Apply each critique lens based on what the diff touches. No subagents — you perform the review directly.

Arguments

  • Identify PR_NUMBER from the PR link.

Critique Lenses

Load and apply whichever references are relevant (they are referenced relative to this skill file path):

  • PR Sanity — Always relevant. CI status, changeset coverage, docs, tests → pr-sanity-critique.md
  • API Decisions — Relevant for component changes. prop naming, component structure, design system consistency (apply when diff touches component files) → api-decision-critique.md

All issues raised by PR Sanity and API Decisions are critical and high importance issues. They take priority over any other code quality or other issues.
