angular-reactivity-review

An automated review agent for Angular, a framework for building web applications. It checks how Angular updates the screen, how data changes are handled, and whether RxJS subscriptions may keep running after they should stop.

In plain words
What is it for?
Use it on Angular component, template, service, and TypeScript files. It reports likely issues with severity, confidence, and suggested fixes, or skips projects that do not use Angular.
Why use it?
It helps catch issues that can leave the screen out of date or cause memory leaks, especially when using OnPush change detection, immutable data, or Angular Signals.

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

angular-reactivity-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 2d 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.

Angular Reactivity Review

Scope:

  • **/*.component.ts
  • **/*.component.html
  • **/*.service.ts
  • **/*.ts Cites: [adversarial-review-protocol]

Scope: Angular component, directive, and service files (.component.ts, .component.html, .service.ts, and general .ts files in Angular projects). Skip this agent entirely if the project has no @angular/core dependency in package.json (or equivalent manifest). Covers Zone.js-based Angular (Angular 2–17) and Angular Signals (Angular 16+ signal(), computed(), effect()).

Output JSON: per ${CLAUDE_PLUGIN_ROOT}/knowledge/review-agent-output-contract.md (Whole-file load: short, canonical schema).

Status: pass=no reactivity issues, warn=potential concerns, fail=likely silent reactivity breakage Severity: error=silent change-detection failure or subscription leak; warning=potential reactivity concern; suggestion=defensive improvement Confidence: high=mechanical Angular fix (use async pipe, markForCheck, unsubscribe); medium=pattern identified but component design may affect the fix; none=requires human judgment

Context needs: full-file

Skip

Return {"status": "skip", "issues": [], "summary": "No Angular files in target"} when:

  • No @angular/core dependency found in the project manifest (package.json, package-lock.json, yarn.lock, etc.)
  • No Angular component/service/directive files in the target set

Detect

Whole-file load: ${CLAUDE_PLUGIN_ROOT}/knowledge/reactive-effect-patterns.md for cross-framework effect/watcher patterns shared with React and Vue agents before running the Angular-specific checks below.

Zone.js change-detection pitfalls:

  • State mutations inside setTimeout / setInterval callbacks when NgZone.runOutsideAngular() is used — Zone.js won't detect them; must call NgZone.run() to trigger CD or use Angular Signals
  • Using native browser APIs (IndexedDB callbacks, third-party library callbacks) that run outside Zone.js without a corresponding NgZone.run() to re-enter the zone
  • Mutating component state inside a Promise.then() that was created before Zone.js could patch it (rare, but occurs with some polyfills)

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.

angular-reactivity-review is an agent published in the GitHub repository bdfinst/agentic-dev-team (277 stars, last pushed yesterday), licensed MIT. It adds 30 tokens to every session and 1,457 once invoked, about $0.0002 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 2026-08-30.
