Add a new skill kind, 'entry-point', and its sole instance at
skills/entry.md. When an orchestrator points an agent at BCQuality,
the agent's first call is Entry: it receives a task context and
returns a dispatch record naming the action skill(s) to invoke.
Routing logic lives in Entry, not in the orchestrator.
Entry structurally follows DO's Source -> Relevance -> Worklist ->
Action pattern but the units it selects are action skills (not
knowledge files) and its output is a dispatch record (not a
findings-report).
Contract highlights:
- Inputs semantics in DO clarified as any-of: orchestrator supplies
whichever listed input types it has; skill must return
'not-applicable' if the subset is insufficient. This matches
the existing al-* canonical skills which declare
[pr-diff, file-path] as alternatives.
- Relevance admits candidates whose inputs intersect
inputs-available, not whose inputs are a subset.
- Dispatched inputs are the intersection, not the full
inputs-available set, to avoid leakage between skills.
- Super-skill precedence in Worklist supersedes a sub-skill only
when the goal is a broader match for the super than the sub.
When the goal specifically names a concern the sub handles
(e.g., 'performance review'), the sub wins and the super is
dropped with reason 'narrower-sub-skill-selected'.
- Skill layer precedence is defined here as custom > community >
microsoft, matching READ's rule for knowledge files.
- skipped[] carries 'superseded-by' for layer-precedence,
sub-skill, and super-skill drops, for traceability.
Propagate the concept through:
- skills/README.md: distinguish the runtime entry-point skill from
the three meta-skill contracts.
- skills/do.md: acknowledge entry-point alongside meta-skills as
the only kinds that live outside a layer.
- README.md: rewrite the Skills and Agent bootstrapping sections
so the bootstrap instruction is 'invoke /skills/entry.md first'.
- agent-consumption.md: update the Mermaid flow and step narrative
to show Entry dispatch, with READ and DO read on demand.
