Likec4 architecture

Skill timseriakov/likec4-architecture-skill/likec4-architecture

Build and maintain software architecture as code with LikeC4 DSL. Use when tasks mention architecture diagrams, C4/context/container/component views, system landscape, dependency/integration maps, or when the user wants architecture generated/evolved from code. Apply for creating new `.c4`/`.likec4` models, updating existing models, validating with LikeC4 CLI, and preparing preview/build/export outputs.From its SKILL.md

LikeC4 Architecture

Model software architecture in LikeC4, keep it executable, and return validation-backed outputs.

Workflow

  1. Scope the model:
  • Identify system boundary and audience.
  • Start with context and container views unless user asks otherwise.
  1. Locate model files:
  • Reuse existing .c4/.likec4 files when present.
  • If missing, bootstrap from assets/likec4-starter/docs/architecture/model.c4.
  1. Model structure before visuals:
  • Define stable element IDs and meaningful names.
  • Add explicit directional relationships with short labels.
  • Add technology/description fields where helpful.
  1. Keep views focused:
  • Build small, purposeful views.
  • Split crowded diagrams by domain, team, or bounded context.
  1. Validate and package:
  • Run npx likec4 validate and fix all errors.
  • Provide npx likec4 start preview command.
  • If requested, provide build/export commands.

Required Quality Gates

  • Do not leave unlabeled ambiguous relationships.
  • Do not leave orphan elements that never appear in views.
  • Prefer domain names over implementation noise in element titles.
  • Finish only after successful CLI validation.

Command Set

Use the minimal commands needed for the task:

npx likec4 validate
npx likec4 start
npx likec4 build -o ./dist
npx likec4 export png -o ./assets/architecture

Output Contract

When architecture files change, return:

  1. Changed files.
  2. Validation result.
  3. One-line purpose for each view.
  4. Preview/build/export command(s) relevant to the request.
