Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# ThinkRail

The agentic IDE that gets better every time you use it, built around the `pi` coding agent. The app is
a thin host that runs `pi` and bridges it to a rich UI; `pi` owns models, skills, compaction, cost, and
session state.

## Read context proportionally

- Use `goal-and-requirements.md` for the product's goal, principles, capabilities, and non-goals.
- Use `architecture.md` for system topology, cross-module decisions, and repo-wide invariants.
- For a pi upgrade or a host workaround around pi, read `pi-compatibility.md`: verify every applicable
  removal gate against the installed SDK, update the registry, and report what was removed or retained.
- Read the owning `SPEC.md` when work is governed by or may alter a module boundary, contract,
  invariant, documented behavior, or architecture decision.
- Localized work does not require unrelated specs or a full repository map.

## Module structure and boundaries

Clear, fractal module boundaries are a top-priority requirement:

- Every package and meaningful directory-level sub-module has a `SPEC.md` stating its responsibility,
  public surface, allowed dependencies, and forbidden reaches.

How to install

The exact contents, by fingerprint
mdr add jetbrains/thinkrail/AGENTS.md@sha256:b56675347cb820eb

The line at the top of this page pins the label git:20261022.9d88588, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
