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 o…

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

LikeC4 Architecture
Model software architecture in LikeC4, keep it executable, and return validation-backed outputs.
Workflow
- Scope the model:
- Identify system boundary and audience.
- Start with context and container views unless user asks otherwise.
- Locate model files:
- Reuse existing
.c4/.likec4files when present. - If missing, bootstrap from
assets/likec4-starter/docs/architecture/model.c4.
- Model structure before visuals:
- Define stable element IDs and meaningful names.
- Add explicit directional relationships with short labels.
- Add technology/description fields where helpful.
- Keep views focused:
- Build small, purposeful views.
- Split crowded diagrams by domain, team, or bounded context.
- Validate and package:
- Run
npx likec4 validateand fix all errors. - Provide
npx likec4 startpreview command. - If requested, provide
build/exportcommands.
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/architectureOutput Contract
When architecture files change, return:
- Changed files.
- Validation result.
- One-line purpose for each view.
- Preview/build/export command(s) relevant to the request.
