Keep the knowledge base updated automatically while coding:
# Start watching a project directory curl -X POST http://localhost:8080/api/watch \ -H "Content-Type: application/json" \ -d '{"path": "/path/to/project"}'Check watcher status
curl http://localhost:8080/api/watch
Stop watching
curl -X DELETE http://localhost:8080/api/watch
The watcher automatically syncs
.rs.ts.tsx.js.jsx.py.gonode_modules/target/.git/__pycache__/dist/build/Query the code graph instead of reading files directly:
# Semantic search across code curl "http://localhost:8080/api/code/search?q=error+handling&language=rust&limit=10"Get symbols in a file (functions, structs, etc.)
curl "http://localhost:8080/api/code/symbols/src%2Flib.rs"
Find all references to a symbol
curl "http://localhost:8080/api/code/references?symbol=AppState&limit=20"
Get file dependencies (imports and dependents)
curl "http://localhost:8080/api/code/dependencies/src%2Fneo4j%2Fclient.rs"
Get call graph for a function
curl "http://localhost:8080/api/code/callgraph?function=handle_request&depth=2&direction=both"
Analyze impact before changing a file
curl "http://localhost:8080/api/code/impact?target=src/lib.rs&target_type=file"
Get architecture overview
curl "http://localhost:8080/api/code/architecture"
Find similar code patterns
curl -X POST http://localhost:8080/api/code/similar
-H "Content-Type: application/json"
-d '{"snippet": "async fn handle_error", "limit": 5}'Find all types implementing a trait
curl "http://localhost:8080/api/code/trait-impls?trait_name=Module"
Find all traits implemented by a type
curl "http://localhost:8080/api/code/type-traits?type_name=Orchestrator"
Get all impl blocks for a type
curl "http://localhost:8080/api/code/impl-blocks?type_name=Neo4jClient"
# Fetch your task context curl http://localhost:8080/api/plans/$PLAN_ID/tasks/$TASK_ID/prompt
curl -X POST http://localhost:8080/api/tasks/$TASK_ID/decisions \ -H "Content-Type: application/json" \ -d '{ "description": "Chose X over Y", "rationale": "Because..." }'
