What it does

Code Review is an agent skill from ozontech/seq-db. Review the current code changes (branch diff vs main, a commit range, or a PR) for seq-db. Delegates to the code-reviewer subagent so the review's file reading and test runs stay out of the main context, then relays ranked findings. Use when the user asks to review changes, a branch, or a diff before opening a PR.

Its SKILL.md is about 410 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 Code review and Subagents. The repository describes itself as: seq-db is a scalable and high-performance database designed for storing and querying logs efficiently. The licence is Apache-2.0.

When your agent uses it

  • The user asks to review changes
  • A diff before opening a PR

Example prompts

  • “/code-review”

Workflow steps

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

  1. Determine scope from the user's request
  2. Spawn the code-reviewer subagent (Agent tool, `subagent_type
  3. Relay the findings. Present the subagent's verdict and findings to the
  4. Do not fix anything unless asked. Reviewing and editing are separate

What it can do on your machine

Read from SKILL.md and the folder at commit 70af159. 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 411 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 191 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
~411

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.

description
Review the current code changes (branch diff vs main, a commit range, or a PR) for seq-db. Delegates to the code-reviewer subagent so the review's file reading and test runs stay out of the main context, then relays ranked findings. Use when the user asks to review changes, a branch, or a diff before opening a PR.

Review changes

Delegate the review to a subagent so the diff reading, context gathering, and any test/lint runs stay out of this conversation's context. You orchestrate and relay; you do not read the whole diff yourself.

Steps

  1. Determine scope from the user's request:
    • No argument → current branch vs main plus uncommitted changes.
    • A commit/range, path(s), or PR number → pass that through verbatim.
  2. Spawn the code-reviewer subagent (Agent tool, subagent_type: "code-reviewer"). Give it the scope and any focus the user asked for (e.g. "concentrate on the sealing path"). One agent is enough; only fan out into several code-reviewer agents if the diff spans clearly independent subsystems and the user asked for a thorough pass.
  3. Relay the findings. Present the subagent's verdict and findings to the user, ranked most-severe first. If code-review reporting via ReportFindings is available, call it once with the verified findings for structured rendering; otherwise present them as a concise markdown list. Do not pad the output — a clean review is a valid result.
  4. Do not fix anything unless asked. Reviewing and editing are separate steps. After presenting findings, offer to fix specific ones on request.
