Build Code Knowledge Graph

Build or update the .gauntlet/graph.db knowledge graph for the current codebase.

Steps

Detect target: Use the current working directory or a user-specified path.
Check for existing graph: If .gauntlet/graph.db exists, run an incremental update. Otherwise, run a full build.

Run the build script:

For full build:

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/graph_build.py <dir>

For incremental update:

python3 ${CLAUDE_PLUGIN_ROOT}/scripts/graph_build.py <dir> --incremental

Report results: Show the JSON output including files parsed, nodes created, edges created, and duration.
Suggest next steps: Recommend searching the graph or running blast radius analysis.

When To Use

At the start of a session to build structural awareness
After significant code changes to update the graph
Before running blast radius analysis or flow tracing
When the user asks about codebase structure

When NOT To Use

Querying a graph that already exists (use gauntlet:graph-search)
Building the challenge knowledge base (use gauntlet:extract)

What Gets Parsed

The graph extracts nodes (File, Class, Function, Type, Test) and edges (CALLS, IMPORTS_FROM, INHERITS, CONTAINS, IMPLEMENTS, TESTED_BY) from 20+ languages including Python, JavaScript, TypeScript, Go, Rust, Java, C/C++, Ruby, and PHP.

Storage

Database: .gauntlet/graph.db (SQLite with WAL mode)
Auto-creates .gauntlet/.gitignore to prevent commits
Incremental updates use SHA-256 hashing to skip unchanged files

Exit Criteria

.gauntlet/graph.db exists and is a valid SQLite file after the skill completes; .gauntlet/.gitignore exists to prevent the database from being committed
Build report JSON includes all four keys: files_parsed, nodes_created, edges_created, duration; values are non-zero for non-empty codebases
Incremental update path used when .gauntlet/graph.db already exists (script invoked with --incremental); full build only on first run
Next-step suggestions presented to the user: search the graph or run blast-radius analysis
