angular-runtime-config

A code review guide for Angular single-page apps running in containers. It checks whether settings such as API addresses and feature flags are supplied when the container starts, rather than fixed when the app is built.

In plain words
What is it for?
Use it to review runtime configuration, startup loading, caching, fallback handling, and precedence between default and runtime values.
Why use it?
It helps one built Docker image work across environments without rebuilding it, while catching exposed secrets and startup configuration failures.

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-runtime-config 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 — 311 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Standard IDs

ID Severity What it checks
ARC-001 P1 API base URL / feature flags baked into environment.ts at build time
ARC-002 P1 No runtime config.json + APP_INITIALIZER/provideAppInitializer pattern
ARC-003 P1 Runtime config not cached synchronously before early-bootstrap code needs it
ARC-004 P0 Secrets or sensitive values placed in the client-visible config.json
ARC-005 P1 No fallback/error handling when the config endpoint is unreachable at startup
ARC-006 P2 Inconsistent precedence between build-time defaults and runtime overrides

Cross-reference: this is the Angular-side counterpart to dotnet-dynamic-configuration — that skill governs the backend's layered configuration providers (appsettings + environment variables + Azure App Configuration); this skill governs how the same promoted container image picks up environment-specific values on the client without a rebuild.


Check A — Build-time config forces per-environment images (ARC-001)

Detection

  1. Inspect src/environments/environment.ts / environment.prod.ts (or fileReplacements in angular.json) for apiBaseUrl, feature-flag booleans, or tenant-specific values.
  2. Confirm whether the Dockerfile/CI pipeline builds a distinct image per environment (ng build --configuration=staging, ng build --configuration=production) rather than building once and promoting the same artifact through environments.
  3. Flag any environment-specific value that only exists as a compiled-in TypeScript constant — changing it requires a rebuild, which breaks "build once, deploy everywhere" and makes the staging-tested image different from the production image.

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-runtime-config is a skill published in the GitHub repository AgenticPawan/FullStack-Pilot (2 stars, last pushed 1mo ago), licensed MIT. It adds 95 tokens to every session and 2,966 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.
