generic-mapreduce SKILL.md skillA
generic-mapreduce from smars-bin-hu/copilot-agentic-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add smars-bin-hu/copilot-agentic-harness/generic-mapreduce@git:20261102.d95f023Pins git:20261102.d95f023 in mdr.lock. Pin the fingerprint instead.

Split a job that needs a lot of reading into parts, hand them in parallel to read-only subagents (mappers), get a summary with sources from each, then put them together yourself. Expensive: use with care. Use only when the user clearly types /generic-mapreduce; an agent must not call it by itself. Keywords: mapreduce, parallel, chunked reading, research, scattered RCA, reading code, reading the knowledge base, brainstorm.
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
# MapReduce: reading in parallel chunks You split the job, hand out the parts, collect the summaries and put them together. A batch of read-only subagents (`mapper`) each reads one part. What it buys is parallel work and a clean context. What it costs is usage: by experience, several times what doing it yourself costs. ## When to Use This Skill **Use it only when the user types `/generic-mapreduce`.** You cannot call it yourself. When parallel work seems worth it, you may tell the user "this suits `/generic-mapreduce`, at roughly several times the usage", and the user decides. It does reading only: - Research: several unrelated directions, each looked into. - A scattered RCA: several possible causes, each with its own logs and code. - Scattered reading of code or the knowledge base: several modules or domains, a summary of each. - Brainstorming: one question, thought through from several angles. **It does no writing.** A mapper has no edit tools and no terminal. To change files in parallel, this is not the skill. ## Prerequisites - The user typed `/generic-mapreduce` in this prompt. The hook lets the calls through because of it; without it, a call of `mapper` is refused. …

How to install
mdr add smars-bin-hu/copilot-agentic-harness/generic-mapreduce@sha256:cfc09cae93b1c3bcThe line at the top of this page pins the label git:20261102.d95f023, 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.
