What is tabs-extension AGENTS.md?

A short guide for AI coding agents working on a Markdown and React tab extension. It points to detailed documents about the code structure and development tools.

Use it when changing the tab extension, its Markdown transformation, runtime behavior, React integration, display variants, tests, linting, or formatting.

It gives an agent the repository context and working rules in one place, reducing the need to search through the project before making changes.

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	$0.00138	$0.00138
Opus 5.5	$0.00055	$0.00055

Security

Grade A, and why

tabs-extension 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.

What it actually says

AGENTS.md

Short index for AI coding agents working on this repository.

Detailed guidance is in docs/AGENTS/:

docs/AGENTS/core.md — package overview and architecture:
- Plugin (MarkdownIt transform), runtime (TabsController), React (hook, TabsRuntime);
- variants (regular, radio, dropdown, accordion);
- key modules and entry points.
docs/AGENTS/dev-infrastructure.md — build, test, and lint:
- npm scripts, Vitest, ESLint, Prettier, Stylelint;
- development workflow.

Use these as the main reference when changing or extending the extension.

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.
