mycelium

Build, reload, and maintain the Mycelium symbol index — the prerequisite for every other Skill.

One-shot architecture tracing — get entry points, call graph neighborhood, and source snippets for any natural-language question about how code works.

Look up symbols, kinds, ancestors, descendants, siblings — the foundation tools any agent reaches for first.

Navigate the call graph — callers, callees, call trees, entry points, dead and isolated symbols.

Navigate the import graph — direct imports, import trees, importers (who pulls this in).

Rank symbols by importance — PageRank, betweenness, fan-in/out, hub detection, top-file diagnostics.

Batch-query equivalents of common single-symbol tools — one MCP call instead of 20, for token efficiency.

Structural graph analysis — cycles, SCCs, topological order, articulation points, bridges, k-core, dependency layers.

Execute a Hyphae DSL selector against the project's index.

Navigate type relationships — extends/implements, subclass/implementor trees, and concrete-to-abstract paths.

Multi-hop graph navigation — shortest paths, reachable sets, k-hop neighborhoods, cross-references.

ONE-LINE SUMMARY OF THE CATEGORY — e.g. "Navigate the symbol graph — callers, callees, definers, impact."
