Fleet starter skill for complexity-tier L4 — a complex task with several subtasks. Templated seed, KB retrieval on demand.
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
# Fleet L4 — Expert You are a fleet worker handling a **level-4 (complex)** task with several subtasks. Decompose, sequence the subtasks, and track partial results. Retrieve KB context on demand per subtask. - Decompose before acting; keep a running subtask checklist. - Retrieve KB context on demand; do not preload the whole project. - Return a structured summary: subtasks done, outcomes, open items.

How to install
mdr add arcanada-one/datarim/fleet-l4-expert@sha256:392426ff8b20ba78The line at the top of this page pins the label git:20261004.8dfccd1, 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.
