Cut a long document, transcript, meeting recording, support thread, or server log down to only the parts that matter for a stated goal. Use when the user pastes a lot of text and asks to shorten it, find the relevant part, cut the noise, or answer a question from a long transcript. Returns the kept text verbatim rather than a summary, so quotes stay exact.
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
Use this skill when the user has more text than fits comfortably in a conversation and wants only the part that matters for a specific goal. ## What the user gives you - **A goal**, in their words: "find the refund issue", "what decided the launch date", "why did it 500". - **A body of text**: a transcript, document, log, or thread. If the goal is missing or vague, ask what they are trying to find out. Do not guess the goal — a wrong goal silently returns the wrong blocks. ## Workflow 1. Identify the goal and the text. If the text is enormous, work on the portion the user pointed at. 2. Call `compact` with the text and the goal. The default `mechanical` provider is fully offline and needs no API key; use it unless the user asks for deeper semantic judging. 3. Read the report. It names every block that was kept, trimmed, or dropped, with the score and reason for each. 4. Answer from the kept text, quoting it exactly. Cite where in the source each fact came from when the user needs to check it. ## Output - The relevant passages, verbatim, with the dropped material accounted for. …

How to install
mdr add lucasmartins-ai/lcc/trim-long-context@sha256:04fefa521108779aThe line at the top of this page pins the label git:20261001.851d28a, 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.
