angular-security

Guidance for securing Angular applications, a web framework for building browser-based software. It covers security-sensitive code, authentication, user input, content security policies, server-side rendering, and related protections.

In plain words
What is it for?
Use it when writing or reviewing security-sensitive Angular code, configuring login systems, handling form input, setting up CSP, securing Angular SSR, or hardening an application.
Why use it?
It helps developers avoid common security mistakes when building or reviewing Angular applications, including cross-site scripting (XSS), where unsafe content can run in a user's browser.

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-security scanned grade A with 1 finding 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.

Unrestricted tool accesslowExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

- **ng add schematics**: Execute arbitrary code — audit all third-party schematics

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

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-security is a skill published in the GitHub repository mamamou/ai-coding-skills (16 stars, last pushed 2mo ago), with no licence file. It adds 207 tokens to every session and 5,542 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
