v0.6.0 — Tool Consolidation & Schema Optimization

Breaking Changes ⚠️

Tool API surface reduced from 27 → 18 tools (~33% reduction). If you reference old tool names in agent configs, update them:

| Removed Tool | Replacement |
|---|---|
| search | search_memory(mode: "vector") |
| search_text | search_memory(mode: "bm25") |
| get_valid_at | get_valid(timestamp: "...") |
| search_code | recall_code(mode: "vector") |
| get_callers | symbol_graph(action: "callers") |
| get_callees | symbol_graph(action: "callees") |
| get_related_symbols | symbol_graph(action: "related") |
| get_index_status | project_info(action: "status") |
| list_projects | project_info(action: "list") |
| get_project_stats | project_info(action: "stats") |
| create_entity | knowledge_graph(action: "create_entity") |
| create_relation | knowledge_graph(action: "create_relation") |
| get_related | knowledge_graph(action: "get_related") |
| detect_communities | knowledge_graph(action: "detect_communities") |

New Features

AST Breadcrumbs: Code chunks now include hierarchical context paths (e.g. src/auth.ts > AuthService > login)
Pre-filtering: recall_code supports path_prefix, language, chunk_type filters applied before RRF fusion
Bounded BFS Symbol Graph Traversal: New SymbolGraphTraverser with frontier-based exploration and cycle detection

Improvements

Schema Token Optimization: All tool descriptions shortened to 1-2 sentences, removed title/format noise from JSON Schema (~40-50% fewer tokens per tool definition)
Polymorphic Tools: Related tools merged into single entry points with action/mode parameters for cleaner agent interaction
