What it installs

Skills (1)

  • c4-model

    Interactively co-build a software architecture using Simon Brown's C4 model (Context, Container, Component, Code). The skill detects the usage mode (greenfield design, retro-documenting from code or prose, review/explanation, update), runs a structured framing dialogue, proposes incremental drafts,

Slash commands (6)

  • /c4m:auto

    Co-build a C4 architecture diagram (Simon Brown's model) interactively. Detects the mode (design, document-code, document-prose, review, update) and runs the matching workflow.

  • /c4m:code

    Retro-document an existing codebase as a C4 diagram. Scans the repo, presents findings, then dialogues to fill ambiguities.

  • /c4m:design

    Design a new system architecture (C4) from scratch via structured dialogue. Skips mode detection — goes straight into Design mode.

  • /c4m:prose

    Extract a C4 architecture from prose (README, ADR, spec, meeting transcript). Fills gaps via dialogue — invents nothing.

  • /c4m:review

    Review or explain an existing C4 diagram. Critique by severity (blocking / important / nice-to-have) or narrate in prose.

  • /c4m:update

    Update an existing C4 diagram — add a container, change a flow, apply review corrections, evolve the architecture.
