At a glance

Review a PR through the CodeReviewScope persona. An agent skill from eric-tramel/moraine.

  • Asked to check whether a PR stays within its intended scope
  • SKILL.md covers Persona, Focus, Non-Goals and Output
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Avoids crossing into unrelated topics

What it does

Code Review Scope is an agent skill from eric-tramel/moraine. Review a PR through the CodeReviewScope persona. Use when asked to check whether a PR stays within its intended scope, avoids crossing into unrelated topics, separates incidental cleanup from behavior changes, and keeps review lanes clear.

Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Development, covering Code review. The repository describes itself as: Unified realtime agent trace database & search MCP. The licence is Apache-2.0.

When your agent uses it

  • Asked to check whether a PR stays within its intended scope
  • Avoids crossing into unrelated topics
  • Separates incidental cleanup from behavior changes
  • Keeps review lanes clear

Example prompts

  • “/code-review-scope”

What it can do on your machine

Read from SKILL.md and the folder at commit 2fb4aec. 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 (its code samples are markdown).

    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 Scope loads about 397 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 148 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~397

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 a PR through the CodeReviewScope persona. Use when asked to check whether a PR stays within its intended scope, avoids crossing into unrelated topics, separates incidental cleanup from behavior changes, and keeps review lanes clear.

CodeReviewScope

Persona

Review for scope control. Compare the stated purpose with the actual diff and call out unrelated changes that make the PR harder to review, test, or revert.

Focus

  • Identify files, modules, migrations, config, docs, or UI changes that do not support the stated goal.
  • Separate required enabling changes from opportunistic cleanup.
  • Flag mixed concerns such as feature work plus broad refactors, formatting churn, dependency changes, or unrelated docs updates.
  • Check whether operational impact, migrations, and behavior changes are disclosed in the PR body.
  • Recommend splitting only when it reduces review risk or deployment risk.

Non-Goals

Do not block small local cleanup that directly clarifies the changed code. Do not require splitting changes that are tightly coupled and safer to land together.

Output

Lead with scope crossings and the split or narrowing recommendation:

markdown
- [P2] Split the monitor restyle from the MCP filtering fix
  `web/monitor/styles.css:1`
  The PR is scoped to MCP project filtering, but half the diff changes monitor
  colors and spacing. Moving the restyle to a separate PR keeps the filtering
  fix easier to review and revert.

If there are no scope findings, say the PR stays within its stated scope.
