review-context-builder

review-context-builder is a skill for Claude Code, Codex from explyt/spring-plugin. It costs 64 tokens per session (1,731 once invoked), scanned A, original, Apache-2.0.

A preparation helper for code reviews. It collects information about affected modules, dependencies, tests, conventions, performance-sensitive paths, and risks.

In plain words
What is it for?
Use it after deciding the review scope and before review passes focused on architecture, tests, conventions, or application responsiveness.
Why use it?
It gives several reviewers shared background before they inspect a change.

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

review-context-builder 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 4d 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 context builder

You do not produce final review findings. Your job is to build shared reusable context that benefits all reviewer subskills.

Inputs

The orchestrator must pass you:

  • the exact review target;
  • the path to REVIEW_SCOPE.md;
  • an explicit focus for this context pass:
    • architecture
    • tests-conventions
    • freeze-safety
    • combined
  • the path where the full result must be written.

What to collect

Depending on the focus:

architecture

Collect:

  • affected modules (e.g. modules/spring-core, modules/spring-web, modules/spring-data) and their dependencies;
  • integration points;
  • contracts between components;
  • side effects and hidden couplings;
  • systemic risks for the review.

tests-conventions

Collect:

  • related tests and test patterns (including modules/test-framework usage);
  • lifecycle and disposal expectations;
  • project conventions relevant to the target;
  • observability, logging, and maintainability expectations;
  • known risk areas.

freeze-safety

A specialized focus for user-perceived responsiveness (typing latency, scroll stutter, slow window opening, EDT freezes). Do not duplicate the reviewer subskill rules — only inventory hot paths and provide reasoning anchors.

Collect from the scope and surrounding code:

  1. Hot-path inventory — explicitly list the in-scope elements of each category with paths/names:
    • renderers: ListCellRenderer, TreeCellRenderer, TableCellRenderer, ColoredListCellRenderer, ColoredTreeCellRenderer, paintComponent, icons in hot render paths;
    • action updates: AnAction.update, ActionPromoter, EditorActionHandler.isEnabledForCaret;
    • service init: @Service constructor / init {}, projectOpened, StartupActivity, ProjectActivity;
    • UI open paths: ToolWindowFactory.createToolWindowContent, DialogWrapper.createCenterPanel, Configurable.createComponent;
    • typing hot path: CompletionContributor, Annotator, ExternalAnnotator, TypedHandlerDelegate, DocumentListener.documentChanged, LineMarkerProvider;
    • event handlers: BulkFileListener, DocumentListener, CaretListener, SelectionListener, messageBus subscribers;
    • dispose paths: dispose(), disposeUIResources(), projectClosed.

What this file has done since we first saw it

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.
