lcp-wysiwid-spec

Use this skill when you are authoring or updating go-lcpd design documentation (the “What You See Is What It Does” / WYSIWID pattern).

References (in-repo)

• go-lcpd/WhatYouSeeIsWhatItDoes.md (background and rationale)

WYSIWID model (summary)

• A Concept is an independent capability. Concepts must not depend on each other.
• A Synchronization connects Concepts into an end-to-end flow/story.

Writing rules (must follow)

• Start with invariants (“Security & Architectural Constraints”). Use RFC 2119 language (MUST / MUST NOT) and include brief rationales.
• Keep Concepts dependency-free:
  • A Concept MUST NOT call actions from other Concepts.
  • A Concept MUST NOT reference other Concepts’ types.
  • Cross-Concept coordination belongs only in Synchronizations.
• Keep structure flat and scannable; prefer short lists, signatures, and data-shape bullets over long prose.
• Use a ubiquitous language: keep terminology consistent across docs and Go identifiers where possible.

Suggested section order (for spec.md)

1. Security & Architectural Constraints
2. Concepts
3. Synchronizations

Example template (shape)

• ### <ConceptName>

  • Purpose: …
  • Domain Model: Thing: field, field
  • Actions: action(arg) -> out (include side effects + error cases)

• ### sync <SyncName>

  • Summary: …
  • Flow: when / where / then (include error branches)

If the flow is complex, add a Mermaid sequence diagram or state chart.

Validation

• Ensure the doc can be read as the “ubiquitous language” for the relevant code.
• If the doc implies behavior changes, implement them and validate with the module’s normal test/lint flow (see $lcp-go-lcpd).
