# Design Authoring (Thin Wrapper) This skill contains **no design methodology of its own**. The canon lives in two places and is loaded by reference: - **Persona, entry gates, working principles, final self-review** → `${CLAUDE_PLUGIN_ROOT}/agents/harnie-designer.md` - **Output contract per altitude** → `${CLAUDE_PLUGIN_ROOT}/instructions/design-authoring-arch.md` (ARCH) or `${CLAUDE_PLUGIN_ROOT}/instructions/design-authoring-detail.md` (DETAIL) If this file ever appears to disagree with those documents, they win. Do not copy their content into this file or into the conversation; Read them and follow them. ## Procedure 1. **Pick the altitude.** Use the altitude definitions in `${CLAUDE_PLUGIN_ROOT}/instructions/model-matrix.md` §1. A standalone request is ARCH or TASK-DETAIL (the detailed-design profile); the CONTRACT altitude is internal to the L pipeline and never a standalone request. When the request is ambiguous, confirm the altitude with the requester once. 2. **Load the canon.** Read the designer agent body and the matching altitude profile. When authoring inline, apply the agent body's entry gates and working principles yourself. When delegating to the `harnie-designer` subagent instead, pass the profile's **absolute path**, the altitude and mode signal, and the output path in the delegation prompt — the agent body requires Reading the profile, so never paste its contents. 3. **Author.** Follow the profile's section contract. Lightweight is the default; use the F
