Capability catalog

Programmatic

from drtoller.framework.capability import build_catalog, get_contract, list_primitives

catalog = build_catalog()          # deterministic snapshot
algs = list_primitives(kind="algorithm")
sgns = get_contract("sgns_v1", kind="algorithm")

Kinds: algorithm, metric, evaluation, storage_backend, parallel_backend, execution_pattern, execution_mode.

CLI

drtoller inspect
drtoller inspect --format json
drtoller inspect --kind metric
drtoller inspect sgns_v1 --kind algorithm --format json
drtoller inspect --schema
drtoller inspect --list-kinds
drtoller inspect --docs   # markdown dump of contracts

Progressive discovery (for agents)

Level	CLI	Content
1	inspect --level 1	ids (+ kinds)
2	inspect --level 2	describe + I/O
3	inspect --level 3	parameters + capabilities
4	inspect --level 4	composition / compatible_with
5	inspect --level 5	documentation_ref + version

drtoller inspect --level 1
drtoller inspect sgns_v1 --kind algorithm --level 3 --format json

Catalog schema 1.1 includes a composition index and per-primitive compatible_with. Drift CI requires catalog ids to cover all runtime registries.
