Generate temporal HTML call graph visualization
Command definition
visualize.mddescription: Generate temporal HTML call graph visualization
Generate an interactive temporal call graph visualization that starts with recent movement/onboarding context, then supports module overview, symbol exploration, hotspots, and cycles.
User input: $ARGUMENTS
Parse input for optional parameters:
- Plain text → directory filter (e.g., `/visualize src/services`)
- `max=N` or "limit N" → sets maxNodes
- `orphans` or `include-orphans` → sets includeOrphans=true
- No input → visualize recent code movement plus entire call graph
Call `index_visualize` with parsed parameters.
Examples:
- `/visualize` → temporal onboarding view with changes, modules, symbols, hotspots, and cycles
- `/visualize src/tools` → only symbols in src/tools/
- `/visualize max=1000` → limit to 1000 nodes
- `/visualize src/indexer orphans` → include disconnected nodes
If the index doesn't exist, run `index_codebase` first.
Return the generated file path and open instructions.
Terminology:
- Modules are path-based code areas, such as `src/tools` or `native`.
- Symbols are indexed named code units, such as functions, methods, classes, or Rust modules.
- Cycles are loops where code can eventually call or depend back on itself.
Search a codebase by meaning, then follow the result into definitions, callers, and dependency paths. open-codebase-index is a local semantic code index for OpenCode, Jcode, Pi, Codex, Claude Code, and other MCP clients.
