Author, review, and maintain diagrams as code across Mermaid, PlantUML, Structurizr DSL, Graphviz DOT, and draw.io XML. Covers swimlane/cross-functional workflows, C4 architecture, sequence, state, ER, dependency, and network diagrams. Use when any agent needs to create or update a diagram in a PRD, ADR, spec, UX flow, or architecture doc.
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
# Diagrams as Code > **Purpose**: One conventions layer for all diagrams produced across Frontier roles. > **Principle**: Text-first, diffable, reviewable, rendered at read-time. Binary formats (PNG, JPG, VSDX) are an export, never the source of truth. > **Scope**: This skill is the convention layer. The `diagram-specialist` sub-agent (`.github/agents/internal/diagram-specialist.agent.md`) owns spawn-and-execute behavior. Each reference file covers one format or quality concern. --- ## When to Use Load this skill any time an agent needs to: - Create a swimlane / cross-functional workflow (e.g. the contract-lifecycle template) - Draw a C4 context / container / component diagram for an ADR or spec - Capture an API or event sequence - Document a state machine or lifecycle - Render an ER diagram or data model - Produce a network / infra / pipeline topology - Convert a legacy Visio file into a diffable code artifact - Review an existing diagram for clarity and correctness --- ## Default Format Policy (Mermaid-First) …

How to install
mdr add jnpiyush/agentx/diagram-as-code@sha256:fce635a7e60e6977The line at the top of this page pins the label v1.0.0, 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.
