What is hostproto-dap-core AGENTS.md?

Project instructions for a debugging host that connects different code engines through the Debug Adapter Protocol (DAP). They define where host behavior ends, how schemas and types must be updated, and which tests to run.

Use them when modifying this project’s DAP host semantics, schemas, TypeScript types, tests, or engine bindings.

They give contributors shared rules for changing host behavior without duplicating definitions or mixing host logic with engine-specific details.

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

Security

Grade A, and why

hostproto-dap-core 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

Agent guidance

This package owns DAP host semantics. A binding (debugpy, delve, …) owns process and protocol facts only; see docs/PROMISE.md for the line.
Never copy a schema in. Change hostproto-semantics.lock.json and run npm run schemas. Bindings pin this package by commit.
Never hand-write a TypeScript interface for a HostProto type; validate with assertValid.
A semantic change needs a case in tests/promise.test.ts against the fake engine first; the real-engine adapters confirm it afterwards.
Run npm test and npx tsc -p tsconfig.json before committing; bindings run npm ci against the new commit.

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.
