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- skipped[] carries 'superseded-by' for layer-precedence,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.

DO contract (skills/do.md)
- New 'sub-skills' optional frontmatter field on action skills: when
present and non-empty, the skill is a super-skill that composes
other action skills.
- New 'Composition (super-skills)' section covering section
interpretation, outcome rollup, summary aggregation, and suppression
scope.
- Output schema gains three optional fields: 'from-sub-skill' on each
finding, top-level 'sub-results[]' carrying nested findings-reports,
and top-level 'skipped-sub-skills[]'.
- Super-skills MUST NOT filter sub-skills by task content; leaves own
task-level applicability and signal via outcome.
- Findings from a failed sub-skill MUST NOT flow into the parent's
findings[] or counts, consistent with DO's rule that consumers
ignore a failed skill's findings. Reports are still preserved in
sub-results[] for traceability.
- Rolled-up non-citation finding ids MUST be prefixed with the sub-
skill id to prevent collisions across sub-skills. Citation-based
ids are already unique via repo path and are not rewritten.
- Outcome rollup rules updated: 'partial' covers S = {partial},
{partial, partial}, and {partial, failed}. Empty worklist rolls up
to 'not-applicable' with outcome-reason.
- Nested super-skills are not permitted in v1.
Reference skills (microsoft/skills/)
- al-code-review.md rewritten as the canonical super-skill: lists
al-performance-review and al-security-review as sub-skills, orch-
estrates invocation, aggregates output, and includes a worked
rolled-up JSON example plus the empty-corpus rollup.
- al-performance-review.md added as a leaf reference skill for the
performance knowledge domain.
- al-security-review.md added as a leaf reference skill for the
security knowledge domain.
- Both leaves retain the leaf-level rules validated in the prior
pass: partial-context message requirement, worklist-scoped
suppression, application-area semantics, and the platform-guarantee
threshold for blocker severity.
README updated to describe leaf vs super-skill and link all three
reference skills.
Two rubber-duck passes tightened the contract and caught schema
violations in the worked examples before commit.

- skills/read.md (READ, Schema + Use) — knowledge-file contract:
frontmatter schema, required/optional sections (normative vs
non-normative), layer precedence with applicability-based conflict
detection, explicit frontmatter matching semantics (including
partial-context handling).
- skills/do.md (DO, Action Skill) — action-skill template:
frontmatter schema, required sections, four-step pattern
(Source -> Relevance -> Worklist -> Action), and the output contract
as a JSON schema with outcome, findings, structured references,
confidence, and mandatory suppression recording. Includes a worked
example.
- skills/write.md (WRITE, New Knowledge) — authoring guide:
atomicity, size, section guidance, field-by-field choices, file
naming, layer choice, pre-PR checklist. Defers to READ for the
format spec.
- README.md — link the three files from the meta-skills section and
update the output-contract paragraph to include outcome and
suppressed.
- agent-consumption.md — update step 5 (Agent emits structured output)
to match the richer DO contract.
