Prune verbose histories, logs, and resolved turns during long debugging or triage sessions into a stateful compact handoff.
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
# Prune context during long sessions Compress accumulated conversation history, trial outputs, and resolved turns into a compact handoff artifact (< 300 tokens). Use during long sessions or before subagent delegation to prevent context degradation and eliminate token waste. ## 1. Trigger Conditions Initiate context pruning when: - The session reaches 15+ turns or approaches token limits. - Iterative debugging left long stack traces, compiler dumps, or reverted edits in history. - The user requests a session summary, checkpoint, `/compact`, or clean handoff. - Preparing to hand off state to an isolated subagent or fresh prompt session. ## 2. Pruning Strategy: Retain vs. Discard - **Retain (Keep in Handoff)**: Exact user objective and constraints, deterministic repro command and exit code, verified architectural invariants, target file paths and lines, and 1-line list of disproven theories. - **Discard (Strip Entirely)**: Chit-chat, full tracebacks, multi-page build logs, speculative opinions, unmodified file reads, and reverted patch diffs. ## 3. Structured Handoff Template Format the compressed state using this schema (< 250 tokens): ```markdown …

How to install
mdr add 00200200/maintainer-skills-lab/mkl-prune-context@sha256:23f3d10a5b01d933The line at the top of this page pins the label git:20261016.1cc940d, 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.
