Recommend the smallest sufficient path; do not invoke it. Core coding needs no advanced skill: answer No advanced skill — use the core fabric_exec path.
| Need | Recommend |
|---|---|
| Finite discover → fan-out → verify work | /skill:fabric-workflow |
| Same-model independent roles and synthesis | /skill:fabric-council |
| Different models compared by a judge | /skill:fabric-fusion |
| Work too large for one context window | /skill:fabric-rlm |
| Evidence-gated or transactional local-file mutation | /skill:fabric-schema |
| Persistent material peer advice | /skill:fabric-advisor |
| Persistent progress toward one measurable goal | /skill:fabric-supervisor |
| One command that infers advisor versus supervisor | /skill:fabric-ambient |
| Durable actor team with mailboxes and CAS tasks | /skill:fabric-swarm |
Prefer the smallest sufficient mechanism. Distinguish workflow/council/fusion by execution shape, RLM by context size, ambient roles by persistence, and swarm by durable multi-actor coordination.
Completion criterion
Complete with one of three outputs: (1) No advanced skill plus one-sentence reasoning for core work; (2) one advanced recommendation, one-sentence reasoning, and an exact /skill:... command that preserves the user’s task as arguments; or (3) one discriminating question when two choices are genuinely tied. Never load or execute a recommended skill yourself.
