SKILL

ynh-compose

Compose harnesses from other harnesses — includes, delegates, profiles, focuses and fork. Use when someone has one working harness and wants to reuse parts of it, share it, or vary it per situation rather than copying folders around.

Topics in the source

  • Compose a harness
  • Before you start
  • Step 1 — Find out what they are copying
  • Step 2 — includes — use artifacts without owning them
  • Step 3 — profiles — one harness, several ways of working
  • Step 4 — focuses — a named way in
  • Step 5 — delegatesto — hand work to a specialist
  • Step 6 — fork — take it and make it yours

Someone with one working harness is one step from the thing that makes ynh worth using. Composition is what separates a harness from a folder of markdown you copy between repos, and it is exactly what a new user will not discover unaided. Five mechanisms. Reach for them in this order, because that is the order of increasing commitment. | Mechanism | Question it answers | |---|---| | includes | can I use someone else's artifacts without copying them? | | profiles | can this harness behave differently in different situations? | | focuses | can I skip explaining what I want every time? | | delegatesto | can this harness hand work to a specialist? | | fork | I want someone's harness, but mine | references/composition-patterns.md — worked patterns, the resolution rules, and the traps Ask directly: Is there anything in this harness you have copied from somewhere else, or that you would want in another project? Copied artifacts are the signal. A skill duplicated across three repos wants to be an include. A rule everyone on the team pastes wants to be a team harness. An include pulls skills/, agents/, rules/ and commands/ from another harness at assembly time. Nothing is copied into the re
