What is Maple AGENTS.md?

Repository-wide instructions for working on the Maple application, covering its product structure, code ownership, setup, runtime environment, and security rules. A worktree is the local folder containing a checked-out version of the code.

Use them before changing Maple code, installing dependencies, configuring the frontend, or starting services.

They help agents understand where changes belong and avoid damaging shared configuration, running services, local changes, or privacy protections.

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	$0.03485	$0.03485
Opus 5.5	$0.01394	$0.01394
Sonnet 5.5	$0.00697	$0.00697
Haiku 4.5	$0.00348	$0.00348

Security

Grade A, and why

Maple 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.

The opening of the file, as written. The whole thing — 294 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Maple agent guide

This file applies to the entire repository. It defines the durable rules an agent should know before changing Maple. Task-specific procedures live under .agents/skills/; load the matching skill before doing that work.

Start here

Confirm the checkout, branch, and worktree state. Preserve unrelated user changes and do not switch branches or rewrite history in a dirty checkout.
Read the relevant source and tests before proposing placement. Do not treat historical design documents as stronger evidence than current code.
Before creating configuration or starting or stopping services, determine whether an external development environment owns this checkout's ignored environment files, local Tauri overlay, ports, or processes. Preserve those resources and follow that environment's lifecycle instructions. Standalone setup and startup examples apply only when no external orchestrator owns the affected resource.
Enter the pinned environment with nix develop. Install dependencies with just install and enable the repository hook with ./setup-hooks.sh.
If frontend/.env.local is absent, create it with test -e frontend/.env.local || cp frontend/.env.example frontend/.env.local. Never overwrite an existing file: it may be externally managed or contain checkout-specific backend and application configuration. Record the selected OpenSecret, feature-flags, and billing endpoints in smoke-test evidence; never put secrets in VITE_* variables.
Choose the runtime you actually need: just dev is web-only; just desktop-dev is the Tauri application and is required for Agent Mode and other native behavior.

Product and runtime map

Maple is a React/Vite application packaged with Tauri for desktop and mobile. OpenSecret is its required backend. Keep these runtime paths distinct:

Research chat: React -> OpenAI JavaScript client -> @opensecret/react encrypted custom fetch -> OpenSecret Responses and Conversations APIs.
Desktop Agent Mode: React -> Maple-owned Tauri commands/events -> MapleAgentService -> embedded pinned Goose -> MapleProvider -> Rust OpenSecret SDK -> /v1/chat/completions.
ACP: an external client edge over a protected local socket into the same Maple Agent service. ACP is not Agent Mode's internal abstraction.
Local proxy: a separate user-facing OpenAI-compatible relay. Research chat and Agent Mode do not internally route through it.

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.
