Read how loaded the current session has become and report it as a tier, so a conversation gets wrapped before its answers start degrading. Use whenever someone asks how the session is holding up, whether it is time to wrap or start fresh, why the agent feels sluggish or forgetful; whenever a strain tick fires; and as a standing habit on long multi-hour work. Triggers on: session strain, is this session too long, should we wrap, context is filling up, running out of context, start a fresh…
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
# Strain A long session degrades before it fails. The context window fills, the same problem comes back a third time, an earlier answer turns out to be wrong — and the work keeps going, because nothing in the loop is watching the loop. Strain is the thing that watches: a small, countable reading of how loaded this conversation has become, reported on a schedule, in a form the user can act on. The failure this exists to prevent is not a crash. It is **silence** — the agent that never mentions the session has gone bad, and lets the user find out from the output. ## The one rule **One session, one reading.** Strain measures a single conversation, identified by its session id. Two agents working the same project in two windows are two sessions and their counts never add up. If you cannot tell which session a number belongs to, it is not a measurement. Every place below that asks you to DO something is a numbered procedure. Follow the steps in order and do not skip one because it seems implied. Every command you need is printed, filled in, in the latest strain tick — copy it from there (it carries this session's key, the state folder and the plugin's path). …

How to install
mdr add jovesun-lab/whetstone/strain@sha256:f6f6e120016d2ffeThe line at the top of this page pins the label git:20261018.8fe4b85, 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.
