Model & cap routing (ATC) for a subscription fleet: declare your accounts once, then a capability-ranked router (`coord-engine route --needs …`) picks the cheapest model that can do the job across every subscription, a cross-account cap ledger keeps traffic inside its windows, and outcome logging demotes a model that keeps failing a task class. Standalone on one account; scales to a coord team of resident dispatchers.
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
# Fulcra Agent ATC A subscription fleet — Claude Max, OpenAI/Codex plans, maybe a local ollama and a hosted overflow lane, across one or several harnesses — has two failure modes that waste money and stall work: it **burns frontier budget on mechanical work** a cheap model would finish, and it **stalls on one capped account** — hitting a window cap on one subscription while another sits idle. ATC (air-traffic control) is the routing layer that fixes both, and it runs on **one account** the same way it runs on a fleet. Three parts: - **The map** — a packaged default model map (`map_version 2026-07-08`) tagging every model by capability (`code`, `architecture`, `writing`, `long-context`, `vision`, `fast`, `tool-use`) and a cost rank (1 = scarcest cap-weight, 9 = locally free). You declare accounts; the map says which models each can run and what they cost. - **The router** — `coord-engine route <team> --needs …`: ranks the models that cover your declared needs **cheapest-capable-first**, filtered to the accounts that have headroom right now. `coord-engine headroom` is the shared cap ledger it reads. …

How to install
mdr add ashfulcra/fulcra-tools/fulcra-agent-atc@sha256:7dfd770c626dee90The line at the top of this page pins the label git:20260907.6e828d3, 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.
