What is vscode-winteriscoming AGENTS.md?

A set of instructions for contributing to Winter Is Coming, a Visual Studio Code color-theme extension with dark and light themes. It explains the theme files, variants, repository layout, and how to work on the project.

Use it when changing theme colors, syntax highlighting, theme variants, or extension metadata, or when checking how to package and run the theme project.

It gives a coding agent the project context needed to edit the right theme files and follow the repository’s conventions. It also makes clear that the project has no runtime code, build step, or tests.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01444	$0.01444
Opus 5.5	$0.00578	$0.00578
Sonnet 5.5	$0.00289	$0.00289
Haiku 4.5	$0.00144	$0.00144

Security

Grade A, and why

vscode-winteriscoming 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.
