Agent startup and graph rag nodes both run an interactive wizard when their
knowledge base has not been built, but neither offered the driver choice that
interactive named-RAG creation has, so both silently produced a yaml store.
A plain agent was the worse of the two: AgentConfig carries only documents, so
there was no way to get a duckdb RAG for one, interactively or declaratively. A
graph node could at least declare driver: in the workflow.
Agent startup now passes prompt_for_driver, and a rag node whose wizard runs is
asked too. The prompt is skipped when the node already declares a driver, and
sits inside the not-fully-specified branch after the non-interactive bail, so
declarative workflows and headless runs are unchanged. Temp RAGs still pass
false: they are deleted on the next run, so a persistent store would only leave
a sidecar behind.
The prompt moves to select_rag_driver rather than being duplicated.
`RagNode` gains an optional `driver`, forwarded into `RagInitConfig` so a
graph node can build its knowledge base on duckdb instead of yaml. Nodes
that name no driver forward `None`, which still resolves to yaml, so
existing workflows are unaffected.
An unknown driver is rejected up front rather than at construction time.
`Rag::create` dispatches unknown drivers to its yaml catch-all, so a typo
would otherwise embed every document and persist the bogus string, after
which every subsequent load fails validation and the agent cannot start.
The check asks `RagData::validate()` through a probe value instead of
restating the list of valid drivers, so the two cannot drift.
Adds QdrantProvider as a read-only driver for pre-existing remote Qdrant
collections, an interactive '.rag attach' wizard, and the sandbox credential
and domain-whitelisting wiring that lets an attached RAG work inside a sandbox.
Attach-only by design: rebuild_indexes bails for both the attached and the
unattached case rather than silently succeeding. Coyote never writes to Qdrant
in this change.
Vectors are never hydrated back from Qdrant. Cosine collections L2-normalize
stored vectors on write, so reading them back returns unit-length copies of the
originals; the YAML vector copy is authoritative and the serialization guard
stays scoped to the duckdb driver alone.
Collections keyed by string or UUID point IDs are rejected at attach time. The
read path parses point ids as u64 inside a filter_map, so such a collection
would otherwise yield zero results with no error.
The three response-shape parsers are pure functions over an already-parsed JSON
body, unit-tested against captured fixtures, with the async wrappers delegating
to them rather than duplicating the logic.
'.rag' now splits its first argument, so '.rag attach <name>' no longer tries to
load a RAG literally named 'attach <name>'.
Phase 3 of the RAG driver abstraction. Adds a `DuckDbProvider` that keeps
vectors and document content in a `.duckdb` sidecar next to the existing
YAML metadata, selected by the `driver: duckdb` field.
- `src/rag/providers/duckdb.rs` (new): vector search via the vss extension
and keyword search via fts, an all-or-nothing hydration path (a partial
read is an error, never a shorter map), and an anti-wipe guard that
refuses the destructive `CREATE OR REPLACE TABLE` when `data.vectors` is
empty while `data.files` is not and the store still holds rows.
- `src/rag/mod.rs`: `sync_documents` now refreshes `bm25`/`node_to_docs`
BEFORE the fallible `provider.rebuild_indexes`. `self.data` is already
mutated by that point, so propagating a provider error afterwards would
leave the derived in-memory state describing the previous corpus while
`data` describes the new one. Both rebuilds are pure functions of
`self.data` and cannot fail, so running them first is always safe.
- `src/config/paths.rs`: sidecar path helpers.
- `src/rag/providers/mod.rs`, `src/config/agent.rs`: driver dispatch and
RAG cache keying.
Also keeps `RequestContext::rag_key` in lockstep with `rag` at the two
sites that were still missing it, so that a cache insert and its matching
invalidate are structurally incapable of disagreeing:
- `use_agent` assigned `self.rag` from the agent but never set `rag_key`.
This one was live. Agent RAGs are inserted under `RagKey::Agent(<name>)`,
so with `rag_key == None` the invalidation guards in `rebuild_rag` and
`edit_rag_docs` matched nothing and `.rebuild rag` left the stale cache
entry in place. Worse, a preceding `.rag <name>` left a stale
`Named(<name>)` key attached to the agent's RAG, pointing the
invalidation at an unrelated RAG's cache entry. Now mirrors the insert
key exactly, yielding `None` when the agent has no RAG.
- `exit_agent` cleared `self.rag` but left `rag_key` behind. Latent rather
than live, since `rebuild_rag`/`edit_rag_docs` both bail on
`rag.is_none()` before reaching the invalidate guards, but the guards
that make it unobservable are not the kind of thing to depend on.
Covered by `use_agent_does_not_carry_stale_rag_key`, and by a new
assertion in `exit_agent_clears_all_agent_state`.
- Hang fix: 120s timeout on compression LLM call + raw_stream
channel-close handling (None => break instead of spinning)
- Supervisor effective active count: stop counting finished
JoinHandles as occupying capacity slots
- Universal tool result size cap: truncate_if_needed() on
ToolResult, applied in eval_tool_calls() after escalation block;
configurable via max_tool_result_chars in AppConfig/AgentConfig
- Windowed compression: compression_keep_last config param keeps
the N most recent messages visible after compression
- Fix pre-existing flaky test: add #[serial] to
handle_list_available_unrestricted_when_no_whitelist so it does
not race with TestConfigDirGuard-based tests that temporarily
populate the agents data dir
