pluto AGENTS.md

Repository guidance for Pluto, a system and command-line tool for running Flutter apps on reMarkable e-ink tablets.

In plain words
What is it for?
It helps agents build, install, discover, debug, capture screenshots of, and hot-reload Flutter apps on supported tablets.
Why use it?
It maps the hardware backends, tools, packages, tests, and device workflow so agents can work in the right part of the project.

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

pluto 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 — 430 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md — Pluto engineering playbook

This is the fast path for an agent (or a new human) to become productive in the Pluto repository. It covers the toolchain, the device workflow, tests, benchmarks, deployment (AOT vs. JIT), hot reload, and the pluto CLI. Read README.md for the elevator pitch and docs/GETTING_STARTED.md for the guided first run; this file is the reference you keep open while working.

What Pluto is

Pluto runs Flutter apps on supported reMarkable e-ink tablets through one discovery-driven product and CLI. Hardware-specific display and lifecycle backends are selected internally:

  • a custom software-rendering Flutter embedder (embedder/, C++), with an e-ink renderer and presenters that drive the panel's waveform controller;
  • the pluto CLI (tools/pluto/, Dart) for device discovery, provisioning, build, install, logs, screenshots, and hot reload;
  • a Flutter Home/launcher (apps/launcher/) that is the common entry point for Pluto applications;
  • pluto_* Dart packages (packages/) exposing device, settings, pen, touch, sensors, manifest, provision, and UI APIs;
  • example and product apps (apps/): counter, motion_lab, ink_lab, validation_lab, ink (drawing), codex (terminal).

Apps ship as release AOT by default. JIT exists only behind explicit --debug flags for hot reload and can never become the boot default.

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.
