What it does

Review Changes is an agent skill from blockscout/frontend. Review a change axis by axis — spec compliance, repo standards, correctness, and a Jev screen — then publish the findings as inline PR comments or into a review file in the task folder.

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `axes.md`, `gh-commands.md` and `output-md.md`).

It sits in Legal & Compliance. The repository describes itself as: Front-end application for Blockscout chain explorer.

When your agent uses it

  • Legal & Compliance work in your project

Example prompts

  • “/review-changes”

Workflow steps

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

  1. Pin the ground
  2. Round first — spawn the axes
  3. Round follow-up — arbitration
  4. Normalize
  5. Publish

What it can do on your machine

Read from SKILL.md and the folder at commit 9438622. 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:

    • git
    • pnpm
    • gh

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

  • Network

    No URLs in SKILL.md. Its commands use git, pnpm and 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

Review Changes loads about 3k tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 1,660 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~3k

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 1,660 words (~3,008 tokens).

“Review a change the way a lead reviewer would: the axes that apply, in parallel, each in its own fresh subagent context, then one normalized report.”
