Use when building, rendering, or debugging the Cursor plugin of this repository — Cursor's plugin layout, what each piece and hook does in the editor and in the `agent` CLI, how hooks run on Windows, and how to probe a behavior the docs do not settle.

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

# Cursor plugin

What Cursor does with a plugin, as observed by probing, not as its docs promise. The docs are wrong or silent
on several points below, so a fact marked **docs** is a hypothesis until a probe confirms it.

Probed on 2026-10-15, Windows 11: editor 3.25.6, CLI `agent` 2026.10.14-941492e. On 2026-10-16, Linux
(maintainer dev, editor 3.25.6) confirmed Unix hook execution and the 10 000-character kit payload (issue
65). Plugin **code** is cross-checked in CI (`rust.yml` on ubuntu, macos, windows); hook behavior in the
editor is documented from the maintainer's dev machine plus the Windows probe, not from manual sessions on
every OS. Re-probe a fact before relying on it at a newer version.

## Probe checklist (#65)

Issue 65 is **closed** when this table matches what you measured. Git marketplace install E2E is tasks 72
and 75, not this task.

| Platform | Hooks (shell, paths, JSON stdout) | `additional_context` size cap |
| --- | --- | --- |
| Windows | Done 2026-10-15: PowerShell 7 wrapper; `${CURSOR_PLUGIN_ROOT}/bin/…` resolves `.cmd` | **10000** (M2 contract limit; kit payload matches spec) |

How to install

The exact contents, by fingerprint

mdr add atnexuslab/tightship/cursor-plugin@sha256:dbc290448c789e3a

The line at the top of this page pins the label git:20261017.0afecbf, 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.
