What is project-context AGENTS.md?

An `AGENTS.md` instruction file for a TypeScript project, defining repository guidelines and coding style. In particular, it requires immutable bindings with `const` instead of `let`.

Use it when editing the project so new or modified TypeScript follows the stated declaration, grouping, and readability guidelines.

It gives coding agents clear local rules, reducing inconsistent style and unwanted changes during development.

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	$0.00143	$0.00143
Opus 5.5	$0.00057	$0.00057

Security

Grade A, and why

project-context 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

Repository Guidelines

TypeScript style

Do not use let. Keep bindings immutable with const. When a value would otherwise need reassignment, split the branches or mutable state transition into small functions that return the value needed by the caller. Do not hide reassignment by mutating an object or array instead.
Optimize declaration layout for readability. Group related declarations by purpose, keep tightly coupled declarations close to their use, and separate distinct declaration groups with a blank line.
Apply these rules to all new and modified code. When touching existing code, bring the affected section into compliance where doing so remains within the scope of the change.

Changes

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.
