#11314, split out per operator directive to ensure focused, bounded Sandboxes.
Scope: high-blast (modifies the core Knowledge Base ingestion pipeline and semantic search capabilities for the agent swarm).
1. The Concept
If the Neo skill substrate functions as a Hierarchical Navigable Small World (HNSW) graph, the sparse map is SKILL.md and the modular chunks are the references/ sub-rules (the focus of #11314). The Bottom Layer must be dense ground truth, accessible on demand.
Currently, the .agents/skills/ directory is not indexed in the Knowledge Base (ChromaDB). This creates an empirical blind spot: if an agent lacks the explicit trigger to load a skill, they cannot discover its internal sub-rules or operational edge cases via semantic search (ask_knowledge_base).
The Proposal: We must add the entire .agents/skills/**/*.md path to the Knowledge Base ingestion pipeline (ai/services/knowledge-base/source/*, etc.). This empowers agents to use semantic RAG to mine operational precedents, rules, and workflows as easily as they query framework documentation.
2. The Rationale
- The Missing HNSW Layer: The recursive "Map vs Atlas" structure (#11314) relies on edge-cases being extracted to sibling files. If an agent is not in the primary workflow, they need a dense vector search to find those edge cases.
- Unknown Unknowns: We frequently encounter situations where an agent doesn't know a rule exists because the skill wasn't loaded in their context. Semantic search bridges this gap.
- Operator Intent: The operator explicitly confirmed: "nested triggers... which compares to chroma. ADDITIONALLY adding skills to KB => that is missing too! and crucial. a skills semantic search."
3. §5.1.1 Reflective Pause (Friction-Driven Proposal)
- Halt reactive code generation: No direct code changes to the
sync-kb script are proposed in this Sandbox.
- Root-cause falsification: The friction is agents failing to adhere to codified substrate rules because the skill didn't trigger. The root cause is the lack of a universal semantic index for operational rules, preventing discovery-by-need.
- Pivot documented: Options include changing the prompt to load more skills (rejected due to budget), or making skills semantically searchable (adopted).

| Option |
When this would be right |
Evidence / falsifier (≥1 source per rejected option) |
Adoption or rationale |
Residual risk |
A (RECOMMENDED): Index .agents/skills/**/*.md into ChromaDB |
When the swarm needs semantic discovery of operational rules and edge-case workflows. |
N/A |
Adopt — Direct realization of the HNSW bottom layer. Fulfills operator directive. Provides O(1) semantic access to the entire substrate. |
Agents might rely too heavily on semantic search instead of explicit routing; requires tuning the context relevance. |
| B (REJECTED): Load all skills into context proactively |
When agent context windows are effectively infinite. |
<user_rules> truncates at ~24KB. AGENTS.md is already 27KB. We cannot proactively load more substrate. |
Reject — Physically impossible given harness limits and token-budget constraints. |
Truncation and cognitive-load dilution. |
C (REJECTED): Rely solely on grep_search for rule discovery |
When agents know exactly which keywords to search for. |
Experience shows agents rarely run blind grep searches for rules unless explicitly prompted. Semantic search (ask_knowledge_base) is the established discovery primitive. |
Reject — grep requires exact lexical matches; operational friction often involves concept-matching. |
High miss rate for critical discipline rules. |
5. Open Questions
OQ1: How should skill documents be categorized in the KB metadata? Currently, we have types like guide, src, ticket. Do we need a new type like skill or rule to allow targeted semantic filtering?
OQ2: Should we exclude SKILL.md routing files from the index to avoid polluting the search results with sparse maps, focusing only on the references/ payload files?
OQ3: Does adding ~25 skills (and growing) impact the mcpSyncMaxChunks volume gate (currently 50)? Will we need to batch the initial ingestion?
