# PM - Diagrams ## Agent mode (`--agent`) Supports `--agent`: runs autonomously in a subagent, drafts the diagram from existing inputs, and returns a short summary + coverage note. - **No flag** → interactive (default); if inputs are heavy, offer agent mode. - **`--agent`** → obey. First check inputs are complete. Anything missing: do NOT invent it - mark `[ASSUMED - what/why]` in the output and summary. Never hallucinate to fill a gap. --- ## Standalone run Runs with or without a Pureinn workspace - it needs no other skill's artifact, so it works as a single tool from an install that never ran `/pureinn`. - No workspace: create just the folder this skill writes into, or write to a path the user names, and say where the file went. Do not scaffold a project, do not invent a `state.json`, and do not send the user to `/pureinn` first. - Read `pureinn-variables.md` / `state.json` where a value is actually used, not at the top of the run. Missing value: continue and name the capability it costs. --- ## What this skill does Generates visual diagrams. It is a **rendering engine + composition knowledge** utility: it owns *how each diagram type is correctly composed*, not the analysis behind it. The correct composition rules for every type live in **`references/[slug].md`** - the skill reads the relevant reference before drawing, so it never renders from memory. **Two rendering modes:** - **Mermaid.js** (primary, Claude Code workflow) - rendered inline in markdown, embedded i
