Knowledge

4 operations. {prefix} is the route prefix passed to MapAgentPrism; the template uses /agentprism.

GET {prefix}/api/knowledge/{collection}/documents

Operation ID: AgentPrismListKnowledgeDocuments

Lists the sources in a collection.

The response is a flat list of source identifiers, not the chunks or their text: a source is the unit a document was uploaded and is deleted as. An unknown collection is not an error — it simply has no sources and returns an empty list. Knowledge storage requires PostgreSQL; without it the response is 501.

POST {prefix}/api/knowledge/{collection}/documents

Operation ID: AgentPrismUploadKnowledgeDocument

Uploads a document to the knowledge base.

The body carries either ‘text’ (the server chunks and embeds it) or ‘chunks’ (pre-chunked). PostgreSQL only: UsePostgreSql and an IEmbeddingGenerator must be registered.

501 Not Implemented	application/problem+json → ProblemDetails	—

DELETE {prefix}/api/knowledge/{collection}/documents/{sourceId}

Operation ID: AgentPrismDeleteKnowledgeDocument

Deletes all chunks of a source.

Every chunk and embedding produced from the source is removed; re-uploading the document is the only way back, and it costs a fresh round of embedding calls. The call is idempotent: an unknown source id still answers 204, because the requested end state — no such source — already holds. Knowledge storage requires PostgreSQL; without it the response is 501.

POST {prefix}/api/knowledge/{collection}/search

Operation ID: AgentPrismSearchKnowledge

Performs a semantic search in a collection (for diagnostics and calibration).

This runs the same retrieval an agent performs, so it is how a retrieval problem is separated from a prompt problem: if the right chunk does not come back here, the agent was never going to see it. The query is embedded, which costs one embedding call per request. Each hit carries its distance — smaller is closer — along with the chunk text and its metadata, so a relevance threshold can be calibrated from real values. Knowledge storage requires PostgreSQL; without it the response is 501.
