Use when loading a built plugin in a harness session to check it — the command per harness and the setup each one needs first.
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
# Session check
Build first with `cargo xtask build`; each command loads what `dist/` holds.
| Harness | Command |
| --- | --- |
| Claude Code | `claude --plugin-dir dist/claude-code` |
| Claude Code, installed with its companions | `claude plugin marketplace add ./dist/claude-code`, then `claude plugin install tightship@tightship`, once the catalogs `DietrichGebert/ponytail`, `ayghri/i-have-adhd`, and `blader/humanizer` are added |
| Cursor | `agent --plugin-dir dist/cursor`, an interactive CLI session |
| Antigravity CLI | `agy plugin validate dist/antigravity-cli --strict` |
## Setup per harness
- **Claude Code** under `--plugin-dir` has no vault option: export `CLAUDE_PLUGIN_OPTION_VAULT_FOLDER`
before `claude`. Its companions are enabled in the user settings, so `--setting-sources project` disables
the plugin for a missing dependency; keep them and pass
`--settings '{"enabledPlugins":{"tightship@tightship":false}}'`, so an installed copy stays off.
- **Cursor**'s `agent` runs from PowerShell with `$env:SHELL = $null`.
- **Antigravity CLI**: `agy plugin install` writes into the adopter's own config, and on Windows needs

How to install
mdr add atnexuslab/tightship/session-check@sha256:6be861d13b27e1bdThe line at the top of this page pins the label git:20261023.787b77e, 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.
