What it does

Code Review is an agent skill from timmo001/system-bridge. Review a pull request, branch, work-in-progress changes, or diff for concrete defects, unmet requirements, and repository convention violations. Keep findings scoped, evidenced, and proportionate.

Its SKILL.md is about 730 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 Pull requests. The repository describes itself as: A bridge for your systems. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Code review
  • Tasks that involve Pull requests

Example prompts

  • “/code-review”

What it can do on your machine

Read from SKILL.md and the folder at commit 504c45d. 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 729 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 369 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~729

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.

Code Review

Load changeset-scope first, then effect for Effect code or effect-principles for other code and independently matching specialist skills. Report only problems introduced or worsened by the changeset.

Review

  • Establish the intended behaviour from the user's request and available issue, PR, or spec. State missing context rather than inventing requirements.
  • Read changed code and its callers to trace actual behaviour. Prioritise correctness, compatibility, security, resource handling, and meaningful performance risks where the change touches them.
  • Follow repository guidance and nearby patterns. In shared repos, consult the user's recently merged work when style is unclear. Cite the rule or precedent for convention findings; skip what linting and formatting already enforce.
  • Do not turn code-smell labels, personal preferences, or hypothetical reuse into findings. Recommend structural changes only to resolve a concrete problem.
  • Apply testing when choosing checks or considering test requests. Missing coverage alone is not a finding; explain the meaningful failure left unprotected.
  • Keep straightforward reviews direct. When a concrete reasoning risk or independent review area warrants another perspective, apply session-coordination to propose a Herdr reviewer with a stronger model or higher effort. Give it the same boundary and applicable skills, and verify its claims before reporting them. Delegate mechanical evidence collection separately when useful; do not make another reviewer a mandatory step for every change.

Findings

Each finding needs:

  • A precise file and line in the change.
  • A concrete failure path or violated requirement, with the triggering conditions.
  • The impact and smallest useful fix direction.

Quote code or include a short example only when it helps establish the problem. If the evidence is incomplete, state the unresolved question or verification limit instead of presenting speculation as a defect.

Delivery

Lead with findings ordered by severity, then material open questions or remaining risks. Keep requirements and repository conventions in view without forcing separate report sections. If there are no concrete findings, say so and briefly state any verification limits. Give an approval recommendation when requested.

Keep the review read-only unless edits are separately requested. Posting review comments, changing PR text, and switching the user's checkout each require the appropriate explicit authorisation. Use the available read-only GitHub tools for PR context; consult owning docs or source for uncertain API behaviour.
