Read from the package source without running it. The installed server may list more.

cgis_analyze_impact
Upstream subgraph of one FQN: everything that reaches it within ``depth`` hops.
cgis_audit_reachability
Reachability/authorization audit — which sources never reach a checkpoint.
cgis_context
Prompt-ready brief on one FQN: its source, class, direct callers and callees.
cgis_drift
Report per-domain architectural drift against declared ideal patterns.
cgis_find_orphans
Classes nothing in production builds, extends or names — dead-code candidates.
cgis_find_symbol
Resolve a partial symbol name to candidate FQNs (substring match, ranked).
cgis_fractal
Report the motif census across the repository's structural tiers.
cgis_get_structure
Members of a module or class — or, for a package prefix, the modules it holds.
cgis_ingest
Scan a local directory, extract all symbols, resolve links, and build the graph DB.
cgis_init_ontology
Propose a starter patterns.yaml from the measured graph (read-only).
cgis_metrics
Whole-graph architectural metrics — coupling bottlenecks, God classes, PageRank.
cgis_overview
Where to start in a graph you know nothing about: sizes and a package map.
cgis_suggest_packages
Suggest sub-package boundaries for a package from its dependency communities.
cgis_trace_flow
Downstream subgraph of one FQN: everything it reaches within ``depth`` hops.
cgis_validate
Report graph integrity as JSON: edge resolution stats + health verdict.
