fix(query_engine): progress tracker leak in expand_entity_uri stop_tracking was only called inside the `if hasattr(execute_sparql)` block; backends without execute_sparql silently leaked a tracker entry. Now stop_tracking(completed) is always reached on the happy path, and stop_tracking(failed) is reached on exception. - fix(query_engine): add skos:relatedMatch to expand_entity_uri FILTER get_alignment_predicates() exposed relatedMatch but the SPARQL filter did not include it, making relatedMatch alignments invisible. - fix(query_engine): sanitize URIs in build_values_clause URIs were interpolated raw into <{uri}> angle-bracket literals. A URI containing > would break the VALUES clause. Now _sanitize_uri is applied to every URI before wrapping. - fix(engine): add skos:relatedMatch to get_alignments and list_alignments FILTER lists now consistent with get_alignment_predicates(). - fix(engine): close SPARQL injection vector in list_alignments Previously only " was escaped in the ontology_uri filter string. A URI containing } would break out of the WHERE block. Now \, ", { and } are all percent-encoded before interpolation. - fix(engine): validate predicate is a full URI in create_alignment Passing a CURIE like "owl:equivalentClass" silently stored a broken triple that get_alignments() could never find. Now raises ProcessingError with a clear message if the predicate does not start with http/https. - fix(tests): rewrite E2E test to actually be end-to-end test_end_to_end_cross_ontology_uri_flow was mocking expand_entity_uri itself, so it only tested build_values_clause string formatting. Now uses a real mock backend with execute_sparql, calls the real expand_entity_uri, and asserts both the backend was queried and the resulting SPARQL template contains both URIs.

`AgnoContextStore` — graph-backed MemoryDb (AgentMemory/storage) - `AgnoKnowledgeGraph` — relational AgentKnowledge with multi-hop GraphRAG - `AgnoDecisionKit` — Agno Toolkit: 6 decision-intelligence tools - `AgnoKGToolkit` — Agno Toolkit: 7 knowledge-graph tools - `AgnoSharedContext` — team-level shared ContextGraph with role scoping ### tests/integrations/agno/ - 110 tests, 0 failures - conftest.py installs comprehensive agno stubs for offline testing - Covers MemoryDb protocol, tool registration, shared memory pool, thread-safety, GraphRAG search, NER/relation extraction, and inference ### cookbook/integrations/ - agno_decision_intelligence.ipynb (finance/loan underwriting) - agno_graphrag_context.ipynb (regulatory compliance GraphRAG) - agno_multi_agent_shared_context.ipynb (multi-agent product strategy team) ### docs/integrations/agno.md - Full reference documentation with examples for all 5 components ## pyproject.toml - Added `agno = ["agno>=1.0.0"]` optional dependency - Added agno to the `all` extra ## Design notes - Zero breaking changes — fully additive - Graceful degradation when agno is not installed - Auto-creates VectorStore(backend="faiss") when none provided - _tools always populated for inspection regardless of agno install state - Works with both real agno package and offline stubs Co-Authored-By: Claude Sonnet 4.6 --- .../agno_decision_intelligence.ipynb | 534 ++++++++++++++ .../integrations/agno_graphrag_context.ipynb | 615 ++++++++++++++++ .../agno_multi_agent_shared_context.ipynb | 676 ++++++++++++++++++ docs/integrations/agno.md | 334 +++++++++ integrations/agno/__init__.py | 50 ++ integrations/agno/context_store.py | 301 ++++++++ integrations/agno/decision_kit.py | 384 ++++++++++ integrations/agno/kg_toolkit.py | 438 ++++++++++++ integrations/agno/knowledge_graph.py | 344 +++++++++ integrations/agno/shared_context.py | 288 ++++++++ pyproject.toml | 5 +- tests/integrations/__init__.py | 1 + tests/integrations/agno/__init__.py | 1 + tests/integrations/agno/conftest.py | 125 ++++ tests/integrations/agno/test_context_store.py | 233 ++++++ tests/integrations/agno/test_decision_kit.py | 256 +++++++ tests/integrations/agno/test_kg_toolkit.py | 366 ++++++++++ .../integrations/agno/test_knowledge_graph.py | 233 ++++++ .../integrations/agno/test_shared_context.py | 237 ++++++ 19 files changed, 5420 insertions(+), 1 deletion(-) create mode 100644 cookbook/integrations/agno_decision_intelligence.ipynb create mode 100644 cookbook/integrations/agno_graphrag_context.ipynb create mode 100644 cookbook/integrations/agno_multi_agent_shared_context.ipynb create mode 100644 docs/integrations/agno.md create mode 100644 integrations/agno/__init__.py create mode 100644 integrations/agno/context_store.py create mode 100644 integrations/agno/decision_kit.py create mode 100644 integrations/agno/kg_toolkit.py create mode 100644 integrations/agno/knowledge_graph.py create mode 100644 integrations/agno/shared_context.py create mode 100644 tests/integrations/__init__.py create mode 100644 tests/integrations/agno/__init__.py create mode 100644 tests/integrations/agno/conftest.py create mode 100644 tests/integrations/agno/test_context_store.py create mode 100644 tests/integrations/agno/test_decision_kit.py create mode 100644 tests/integrations/agno/test_kg_toolkit.py create mode 100644 tests/integrations/agno/test_knowledge_graph.py create mode 100644 tests/integrations/agno/test_shared_context.py diff --git a/cookbook/integrations/agno_decision_intelligence.ipynb b/cookbook/integrations/agno_decision_intelligence.ipynb new file mode 100644 index 00000000..168f6e92 --- /dev/null +++ b/cookbook/integrations/agno_decision_intelligence.ipynb @@ -0,0 +1,534 @@ +{ + "cells": [ + { + "cell_type": "markdown", + "id": "title", + "metadata": {}, + "source": [ + "# Agno × Semantica: Decision Intelligence Agent\n", + "\n", + "This notebook shows how to wire Semantica's **Decision Intelligence** stack into an Agno agent so it can:\n", + "\n", + "- Record every decision it makes with full reasoning provenance\n", + "- Search historical precedents before acting\n", + "- Validate decisions against policy rules\n", + "- Trace causal chains across decisions\n", + "- Accumulate institutional knowledge that survives across sessions\n", + "\n", + "**Domain used:** Financial loan underwriting (easily adapted to healthcare, legal, HR, etc.)\n", + "\n", + "---\n", + "\n", + "## Architecture\n", + "\n", + "```\n", + "Agno Agent\n", + " ├── memory=AgnoContextStore ← graph-backed persistent memory\n", + " └── tools=[AgnoDecisionKit] ← decision tools the LLM can call\n", + " │\n", + " ├── record_decision ← Semantica AgentContext.record_decision()\n", + " ├── find_precedents ← Semantica AgentContext.find_precedents_advanced()\n", + " ├── trace_causal_chain ← Semantica ContextGraph.trace_decision_causality()\n", + " ├── analyze_impact ← Semantica AgentContext.analyze_decision_influence()\n", + " ├── check_policy ← Semantica PolicyEngine\n", + " └── get_decision_summary ← Semantica AgentContext.get_context_insights()\n", + "```\n", + "\n", + "## Install\n", + "\n", + "```bash\n", + "pip install semantica[agno]\n", + "```" + ] + }, + { + "cell_type": "markdown", + "id": "setup-section", + "metadata": {}, + "source": [ + "## 1.

distribution - pyproject.toml: add integrations* to packages.find include so pip install semantica[agno] ships the integration context_store.py - upsert_memory(): run NERExtractor after store() to index entities into the ContextGraph - delete_memory() / drop_table() / clear(): call AgentContext.forget() to propagate deletions to vector/graph storage - find_precedents(): pass limit parameter to find_precedents_advanced() - retrieve(): pass limit as max_results to AgentContext.retrieve() - add get_context_for_prompt() for automatic system-prompt injection knowledge_graph.py - __init__: wire graph_builder.graph_store = self._graph so build() persists into the ContextGraph - add internal AgentContext for vector retrieval (shared ContextGraph) - search(): use AgentContext.retrieve() for vector similarity; keyword scoring as fallback - _ingest_text(): add paragraph-level chunking before NER/relation extraction (parse → split → NER → relation extract → graph build) - get_graph_context(): return structured subgraph with edge types via ContextGraph.get_neighbors() - load_urls(): validate scheme (http/https only) to prevent SSRF decision_kit.py - check_policy(): replace broken PolicyEngine.check_compliance() call with inline _eval_rule() that evaluates simple field-op-value rules; return compliant=False (not True) on failure — closes security bug kg_toolkit.py - add_to_graph(): fix add_node(node_id=, node_type=) and add_edge(source_id=, target_id=, edge_type=) to match real API - query_graph(): use find_nodes() (no label param) + keyword filter - find_related(): use get_neighbors(node_id=) returning List[Dict] - infer_facts() / export_subgraph(): use find_nodes() public API instead of private _nodes dict shared_context.py - _AgentScopedStore: store shared context as self._context (not self._ctx) so all inherited AgnoContextStore methods work correctly tests/integrations/agno/test_kg_toolkit.py - _FakeGraph: rewrite to
