Persona: Implementer

REFERENCE MODE: This skill is a persona shell. It declares the implementer work identity and the composition it resolves to; it carries no executable workflow of its own.

The implementer is the work-activity persona for building and modifying production code. Its primary profile is implementation; it also applies the quality ref so every implementation task carries the code-quality lens.

Composition

The persona resolver (manage-personas resolve) flattens this persona's composition DAG into a deduped skills[]:

• Base — plan-marshall:persona-plan-marshall-agent (the unconditional foundational base every persona inherits).
• Applies (ref) — plan-marshall:ref-code-quality, declared in the composes: frontmatter (the quality profile maps to this ref).
• Profile × domain — for each entry in profiles: (implementation, quality), the resolver merges the profile × {domains} domain skills resolved via the Extension API.

Profiles

• implementation (primary) — the identity profile a task with profile: implementation is reverse-looked-up to.
• quality (secondary) — applies the code-quality ref alongside implementation work.
