dawnai AGENTS.md

A repository guide for people and coding agents working in the Dawn monorepo, a codebase containing several related projects. It explains the workspace layout, contribution rules, and what counts as finished.

In plain words
What is it for?
Use it when starting work in the Dawn repository, checking the definition of done, or following links to related contribution documents.
Why use it?
It gives contributors one agreed set of rules and helps them find the right files. It also prevents confusion with Dawn’s separate runtime memory feature, which uses a file with the same name.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

dawnai 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 223 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Standards for anyone — human or coding agent — working in this repository: the workspace map, the Definition of Done, and the conventions that keep changes consistent.

What this is (and isn't)

This is the repo-root contributor/agent standards doc — how to find your way around the Dawn monorepo, what "done" means for a change, and the rules that keep the codebase consistent. It's the canonical entrypoint; see Cross-links for how it relates to CONTRIBUTING.md and CONTRIBUTORS.md.

This is not the runtime workspace/AGENTS.md capability. Dawn ships a built-in capability (packages/core/src/capabilities/built-in/agents-md.ts) that auto-injects the contents of an app's <appRoot>/workspace/AGENTS.md into that agent's system prompt as its persistent "# Memory" — re-read every turn, updated by the agent itself via writeFile. That's an end-user Dawn app feature, documented at dawnai.org/docs/memory. The name collision is real: this file (repo root, for contributors) and that file (inside a generated app's workspace/, for the agent at runtime) share a filename but nothing else. If you're looking for the runtime feature, this isn't it.

Workspace map

Every packages/* directory is a pnpm workspace member (verify: pnpm -r list --depth -1). One-line purpose is each package's own README.md first line.

Core framework

Package Purpose
@dawn-ai/sdk The author-facing TypeScript SDK — agent(), defineMiddleware(), allow()/reject(), and the type primitives the CLI consumes.
@dawn-ai/core Filesystem-based route discovery, app config loading, state-field resolution, and typegen primitives that the Dawn CLI builds on.
@dawn-ai/cli The dawn CLI — local HMR dev runtime, route execution, validation, typegen, and the build step that produces LangSmith deployment artifacts.
@dawn-ai/langgraph LangGraph runtime adapters and route module contracts (graphAdapter, workflowAdapter, defineEntry) used by the CLI.
@dawn-ai/langchain LangChain backend adapters — materializes chain routes and provider-aware agent routes (tool conversion, streaming, retry).

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.
