What it does

Review is an agent skill from guardana/guardana. Pre-ship code review by a fresh-context Opus reviewer that checks the change against this project's hard rules — a false green, a channel rebuilt field by field, engine purity, schema versions, tenancy, the fixture pair, the five documentation places. Use after the gate is green and before /ship on every M or L change.

Its SKILL.md is about 320 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 Security, covering Prompt injection and agent security. It works with Model Context Protocol. The repository describes itself as: Open-source AI security verification for model artifacts, live endpoints, MCP servers, and recorded agent traces. Reproducible evidence for release decisions. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Prompt injection and agent security

Example prompts

  • “/review”

What it can do on your machine

Read from SKILL.md and the folder at commit 616c63b. 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

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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 loads about 315 tokens when it runs. Until then it costs about 82 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
~82
When it runs · the whole SKILL.md, loaded when a task matches
~315

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.

Review this change.

Range: $ARGUMENTS (If the range is empty, review the uncommitted working tree: git diff plus untracked files from git status --short.)

In-flight work files — read the one that matches the change for its goal and done-criteria:

ls .work/*.md 2>/dev/null || echo "none"

Changed files right now:

git status --short | head -60

Other people's uncommitted work may sit in this tree. Review only what belongs to the change described by the work file or the range; list anything else under "not reviewed".

When the work file names an issue, check each ticked acceptance box against its evidence and say which are not proven; a closing keyword over an unproven box is a finding.

Follow your review order and report format exactly.

How many tokens does Review use?

About 315 tokens (SKILL.md is roughly 1.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
