| description | Clarify domain concepts, language, boundaries, and durable architectural decisions. Use when terminology is ambiguous, the user is shaping a domain model, or a design depends on resolving what concepts mean. |
Model the domain
Build a precise shared understanding of the concepts that matter to the current
decision. Read existing glossaries, context maps, ADRs, code, and tests when
they provide relevant evidence.
Sharpen the model
- Identify overloaded terms, hidden distinctions, and conflicting definitions.
- Use concrete scenarios and edge cases to test whether concepts and boundaries
hold.
- Compare the stated model with behavior in the code and surface material
contradictions.
- Propose clear language when ambiguity is blocking progress, while respecting
established repository terminology that remains accurate.
Ask the user to resolve a term only when their intent cannot be inferred safely
and the distinction affects the outcome.
Record durable knowledge proportionally
Update a glossary or context map when the user requests it or when a resolved
term is durable, project-specific, and useful beyond the current conversation.
Follow an existing repository format first; otherwise use the
context format as a lightweight starting point.
Record an ADR only when a decision is costly to reverse, surprising without its
context, and based on a meaningful tradeoff. Follow existing ADR conventions or
use the ADR format. Do not create artifacts merely to complete
the workflow.
Keep domain definitions separate from implementation plans. Report unresolved
ambiguity and artifact changes explicitly.
