agent-review

agent-review is a skill for Claude Code, Codex from leenspace/contextur. It costs 27 tokens per session (5,093 once invoked), scanned A, original, MIT.

A code-review workflow that compares your changes with the develop branch—the shared branch where upcoming work is combined—and produces a pull-request-style review.

In plain words
What is it for?
Use it before opening a pull request. It reviews code quality, bugs, architecture, technical debt, performance, data-layer changes, and user-interface changes when those areas are affected.
Why use it?
It gathers the relevant changes and surrounding code, then checks them from several viewpoints so bugs, design problems, and rule violations are easier to spot before review.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Review vs Develop

Collects a rich context bundle (diff, stat, commit log, selected full file contents, consumer graph) then dispatches up to ten subagents: six-to-eight specialist reviewers run in parallel, then a challenger validates Critical findings, and a synthesis agent runs last to produce an executive summary.

Subagent Always runs? Triggered by
code-quality-reviewer ✅ Yes All diffs
bug-reviewer ✅ Yes All diffs
architecture-reviewer ✅ Yes All diffs
pre-pr-validator ✅ Yes All diffs
tech-debt-reviewer ✅ Yes All diffs
perf-reviewer Conditional Files in presentation/, *_bloc.dart, *_cubit.dart
data-layer-reviewer Conditional Files in data/service/, data/dto/, data/source/, data/repository/, data/mapper/
ui-reviewer Conditional Files in presentation/pages/, presentation/widgets/, or any *_page.dart/*_widget.dart
finding-challenger ✅ Yes (runs after parallel reviewers) All Critical/Blocker findings from above subagents
review-synthesizer ✅ Yes (runs last) All diffs — reads outputs of all other subagents + challenger report

steps:

  • agent: prompt: | Run git fetch origin with 'all' permissions to bypass sandbox restrictions for SSH key permissions.

  • run: git log develop..HEAD --oneline

  • run: git diff --stat develop...HEAD

  • run: git diff --name-only develop...HEAD

  • run: git diff develop...HEAD

  • agent: prompt: | You have the output of git diff --name-only develop...HEAD from the previous step.

      ## Pre-review configuration
    
      ### Step A — Classify conditional reviewers and path groups
    
      **A1 — Conditional reviewers:** Scan the changed file list and determine which conditional subagents apply:
    
      - `perf-reviewer` → triggered if any file is under `presentation/` OR matches `*_bloc.dart` / `*_cubit.dart`
      - `data-layer-reviewer` → triggered if any file path includes `data/service/`, `data/dto/`, `data/source/`, `data/repository/`, or `data/mapper/`
      - `ui-reviewer` → triggered if any file is under `presentation/pages/` or `presentation/widgets/`, or matches `*_page.dart` / `*_widget.dart`
    
      Build two lists:
      - `ALWAYS_REVIEWERS`: `code-quality-reviewer`, `bug-reviewer`, `architecture-reviewer`, `pre-pr-validator`, `tech-debt-reviewer`
      - `CONDITIONAL_REVIEWERS`: the subset of `perf-reviewer`, `data-layer-reviewer`, `ui-reviewer` that are triggered
    
      **A2 — Path groups:** Parse the changed file list and group files into logical review segments using this hierarchy (apply the first matching rule):
    
      | Path pattern | Group label |
      |---|---|
      | `packages/features/<feature>/lib/src/<segment>/` or files directly under `lib/src/<segment>/` | `<feature>/<segment>` (e.g. `store_oechsle/search`) |
      | `packages/features/<feature>/test/` | `<feature>/test` |
      | `packages/features/<feature>/` (anything else) | `<feature>` |
      | `packages/core/` | `core` |
      | `packages/libraries/<lib>/` | `<lib>` |
      | `apps/<app>/` | `apps/<app>` |
      | `.cursor/` | `project config` |
      | anything else | `other` |
    
      Build `PATH_GROUPS`: a deduplicated, sorted list of group labels present in this diff.
      For each group, also record the path prefix used to match files into it (needed for filtering in the orchestration step).
    
      ### Step B — Ask the user
    
      Use the `AskQuestion` tool to present **2–3 questions at once**:
    
      **Q1 (multi-select, id: `reviewers`):** "The following reviewers always run: code-quality-reviewer, bug-reviewer, architecture-reviewer, pre-pr-validator, tech-debt-reviewer. Which additional reviewers would you like to enable?"
      - Do NOT include the 5 core reviewers (`code-quality-reviewer`, `bug-reviewer`, `architecture-reviewer`, `pre-pr-validator`, `tech-debt-reviewer`) as options — they always run and are non-negotiable.
      - Do NOT list `finding-challenger` or `review-synthesizer` — they always run and are not user-configurable.
      - List ONLY the conditional reviewers that are in `CONDITIONAL_REVIEWERS`:
        - `perf-reviewer` — Widget rebuilds, memory leaks, BLoC state efficiency
        - `data-layer-reviewer` — Retrofit, DTOs, DataSource/Repository patterns
        - `ui-reviewer` — UI Kit compliance, design tokens, Agora* components
      - Pre-select all reviewers in `CONDITIONAL_REVIEWERS` by default; the user may deselect any of them.
      - If `CONDITIONAL_REVIEWERS` is empty, skip Q1 entirely and inform the user that only the 5 core reviewers apply for this diff.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agent-review is a skill published in the GitHub repository leenspace/contextur (7 stars, last pushed 2mo ago), licensed MIT. It adds 27 tokens to every session and 5,093 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
