c4-diagrams from intent-driven-dev/intent-driven-template is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when explaining existing code architecture, visualizing a new system before detailed design, mapping software boundaries, or creating C4-style diagrams in ASCII or Mermaid.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# C4 Diagrams ## Overview Use C4 diagrams to clarify software architecture before detailed design. Focus on boundaries, responsibilities, actors, dependencies, and data flow; draw only the levels that add value. ## First Gates Before diagramming, determine these choices. If the user already specified one, honor it. If multiple choices are ambiguous, ask one concise combined question. | Choice | Options | Default behavior | | --- | --- | --- | | Purpose | Existing code, new system, design review | Existing code requires codebase exploration first; new systems require assumptions called out. | | Format | ASCII, Mermaid | Ask the user. Mermaid means plain Mermaid syntax, not C4-specific Mermaid. | | Rigor | Strict C4, lightweight C4-inspired, hybrid | Ask the user. Do not decide silently. | If the user asks to skip questions for speed, still preserve unresolved choices as explicit assumptions and keep the first diagram lightweight. ## Workflow 1. Establish purpose, format, and rigor. …

How to install
mdr add intent-driven-dev/intent-driven-template/c4-diagrams@sha256:5ba43fe1b6e7c763The line at the top of this page pins the label git:20260510.a8b8231, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
