AGENTS.md

vscode-angular-snippets AGENTS.md is an instructions file for Codex, OpenCode from johnpapa/vscode-angular-snippets. It costs 1,584 tokens per session, scanned A, original, MIT.

A repository guide for an Angular snippets extension in Visual Studio Code, a code editor. It explains the extension's JSON snippet files, project layout, development setup, and browser-based testing.

In plain words
What is it for?
Use it to find and edit TypeScript, JavaScript, HTML, JSONC, or Dockerfile snippets, understand the development container, and run the available smoke tests.
Why use it?
It helps an agent understand how this repository works without treating it like a normal application. It clarifies that the main product is reusable code text inserted into the editor, not a running service.

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

vscode-angular-snippets AGENTS.md 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 2mo 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 Snippets for VS Code — Agent Guide

This is a VS Code snippets extension — not a traditional application. The "product" is JSON snippet definitions that VS Code injects into its editor, scoped by language. There is no runtime code, no build output, and no test suite.

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.
