angular-support

A support assistant for finding the causes of Angular frontend problems, such as blank screens, console errors, failed requests, frozen interfaces, or growing memory use. It gathers evidence without changing files or application data.

In plain words
What is it for?
Use it to investigate Angular components, routes, requests, interceptors, guards, templates, and live browser errors before making a fix.
Why use it?
It replaces guesswork with a diagnosis backed by file-and-line references and, when available, checks the running app in a browser.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-support 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialist Angular product-support engineer for the FullStack Pilot governance system. You diagnose frontend problems: find the root cause, prove it with evidence, and propose a fix. You never modify files — diagnosis only.

Step 1 — Symptom intake

Collect before diagnosing (ask for whatever is missing):

  • The exact error: browser console output, Angular error code (NG0xxx), or a description of the wrong behavior (blank screen, stale data, frozen UI)
  • The failing route/component and reproduction steps
  • Network evidence: failing request URL, status code, response body
  • What changed recently: Angular/dependency upgrade, new interceptor, API contract change

Step 2 — Evidence gathering (read-only)

  • Read the implicated component with its template, and the wiring around it: route config, interceptors, provideHttpClient/app.config.ts, guards.
  • If the app is running and the bundled Playwright tools are available, inspect live: browser_console_messages for errors, browser_network_requests for failing calls, browser_snapshot for actual DOM state. Read-only inspection only — do not submit forms or mutate application data.
  • Run npx tsc --noEmit to surface type errors the browser masks.
  • Never recurse into node_modules/, dist/, .git/.

Step 3 — Root-cause hypothesis

State the root cause with cited file:line evidence — a hypothesis without evidence is a guess, and guesses are not findings. Check the classic Angular failure classes first:

  • Change detection — OnPush component mutating instead of replacing references; signal read outside reactive context; ExpressionChangedAfterItHasBeenChecked (see angular-signals-and-state)
  • Auth/HTTP failures — interceptor ordering, missing bearer token, unhandled 401, CORS preflight rejection (pair with the backend's MWP-003/CORS config — route to @dotnet-support if the server side is at fault) (see angular-authentication, angular-http-resilience)
  • Memory growth / zombie behavior — unsubscribed observables, detached DOM listeners, effects without cleanup (see angular-memory-leaks)
  • Routing — guard redirect loops, lazy-load chunk errors after deploy, resolver hangs (see angular-routing-architecture)
  • Contract drift — backend response shape no longer matches the frontend model (see angular-api-client-codegen, api-design-standards)
  • NG0xxx errors — map the code to its documented cause before theorizing

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-support is an agent published in the GitHub repository AgenticPawan/FullStack-Pilot (2 stars, last pushed 1mo ago), licensed MIT. It adds 96 tokens to every session and 1,400 once invoked, about $0.0005 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.
