feat(tool-search): Jev over an embedding top-20 by default; measured on the Composio catalogue - #6438
Conversation
Add a JSONL fixture file containing intents for tool search tests, providing sample data to support test coverage for search functionality. Auto-committed-on: macbook
The benchmark now tracks and reports accuracy separately for composio and core tool sources, and falls back to the signed-in TinyHumans session when no API key is set, matching product behavior. Auto-committed-on: macbook
The tinyjevclient dependency is temporarily pointed at a local path as part of a benchmark experiment testing size-aware probability tolerance, pending upstream PR. This change is not intended for production and should be reverted once the experiment concludes. Auto-committed-on: macbook
Auto-committed-on: macbook
The discovery module is reorganized into a subdirectory to accommodate the new embedding ranker component, which is added as a separate module and re-exported for public use. Auto-committed-on: macbook
Refactored the disk cache loading logic in `with_disk_cache` to use a chain of combinators (`ok`, `and_then`, `filter`) instead of nested `if let` conditions. This makes the control flow more linear and readable while preserving the same behavior: only a valid, signature-matching cache file is loaded, and any failure results in an empty cache. Auto-committed-on: macbook
The tool search benchmark now supports an `--embedding` flag that switches the Jev ranker's retriever from BM25 to the process's configured embedding provider, with a disk cache so the catalogue is embedded only once per process. The TinyHumansJevRanker also reuses the embedding retriever across rebuilds, falling back to BM25 when the provider cannot embed, so family decisions are cut by meaning rather than shared words. Auto-committed-on: macbook
Remove the JevRankerConfig from the use statement in the JEV ranker setup, as it is no longer referenced in the code. Auto-committed-on: macbook
Resolves the tool-search-bench / tool-dialect-bench bin table and keeps both the discovery policy and the pinned tool dialect in the turn harness. Co-authored-by: Medulla <medulla@tinyhumans.ai>
…nyagents on main + tinytools main Co-authored-by: Medulla <medulla@tinyhumans.ai>
The TinyHumansJevRanker now supports a per-evaluation deadline, defaulting to six seconds, which is applied to the TinyJevEvaluator. This bounds slow proxy responses and triggers a BM25 fallback within the turn, while the benchmark tool sets a 20-second deadline for its runs. The change also simplifies the recall accounting in the benchmark by using an if-let binding instead of map. Auto-committed-on: macbook
Adds a row to the binary index table for `tool-search-bench`, which compares `tool_search` rankers (bm25, overlap, embedding, jev) against the real orchestrator registry and recorded Composio catalogues using the intents fixture. Auto-committed-on: macbook
…rch ranking Adds a planning document recording the measured baseline for the `tool_search` ranking work, including benchmark methodology, per-ranker results across 160 intents and 1,000 Composio actions, and the rationale for the product default of family-first selection with an embedding-based cut.

Run the explicitly selected embedding ranker.
--ranker embedding is accepted by the help text, but this condition also requires --embedding. Without that second flag, the benchmark registers no ranker and exits after printing an empty report. Register the standalone embedding ranker when args.ranker == "embedding".

Honor --embedding in the signed-in fallback. The family strategy is passed through correctly, but the retriever choice is not. When environment credentials are absent, TinyHumansJevRanker::current replaces the configured retriever with retriever_for(&config). If the process embedding provider is usable, --embedding=false still runs with embeddings while the report is labeled jev(retrieve+bm25). The resulting metrics are mislabeled and are not comparable with BM25 results. Preserve the benchmark's configured retriever at this fallback boundary, or add an explicit retriever override without changing the product default.

Keep the detailed Jev report lookup aligned with the report name.
This code now stores names such as jev(family+embedding), but the detailed token pass still searches for r.ranker == "jev" on Line 553. The condition never matches, so the token and USD columns remain unset for every Jev run. Match the Jev prefix or retain the ranker kind separately.

Serialize cold-cache initialization.
When concurrent searches use the same EmbeddingToolRanker, both calls can capture the same full missing catalogue before either call writes to the cache. For the documented 1,215-tool catalogue, each call can submit 19 embedding batches. This increases provider load and can trigger rate-limit errors. The harness then falls back to BM25, so the supported impact is degraded semantic ranking rather than a major availability failure.
Guard ensure_cached with shared asynchronous initialization or an in-flight mechanism so one call populates each missing entry before concurrent calls recheck the cache.

Validate vector dimensions before cosine scoring.
cosine truncates unequal vectors because zip stops at the shorter input. Disk-cache loading validates only the provider signature, and catalogue embedding validates only the number of returned vectors. The query path also passes the first returned vector to cosine without checking its length. A wrong-length cache, catalogue vector, or query vector can therefore produce incorrect scores and rankings.
Validate every vector against provider.dimensions(). Ignore invalid disk entries so ensure_cached regenerates them. Return RankError::Backend for invalid catalogue or query output.

Invalidate the cached retriever when the embedding signature changes.
current() reloads the configuration, but the cache fingerprint includes only the Jev credential and backend URL. A changed embedding provider, model, or dimensions therefore returns the old cached JevRanker.
Add embedding_signature: String to Cached. Compute it with openhuman_core::inference::embedding_host::format_embedding_signature(&config.memory.embedding_provider, &config.memory.embedding_model, config.memory.embedding_dimensions). Require both fingerprints for the ranker cache hit. Reuse entry.retriever after a Jev credential or backend change only when the embedding signatures match; otherwise call retriever_for(&config) and store the new signature.

…on missing embeddings The default Jev ranker strategy changes from FamilyThenDecide to RetrieveThenDecide, using the embedding provider to retrieve the top 20 tools by meaning before a single Jev evaluation with a 6-second deadline. When no usable embedding provider is available, the retriever now returns an error instead of falling back to BM25, because a lexical shortlist would cap Jev at BM25's recall (measured at 70% on the Composio catalogue) while adding a network round trip. A new test verifies that a `none` embedding provider disables the search outright. Auto-committed-on: macbook
…ev search The product ranker now retrieves the top 20 tools by meaning through the process's embedding provider and decides with one Jev evaluation, one proxy round trip. Without a usable embedding provider the ranker returns an error and the harness's BM25 bridge answers alone: a Jev decision over a lexical shortlist was measured to add a round trip and nothing else.

…nged tools Add a test that verifies the embedding ranker only embeds new or changed tool descriptions incrementally, rather than re-embedding the entire catalogue, when a new toolkit is connected or an existing tool's description is rewritten. Auto-committed-on: macbook

Correct the cache lifecycle description.
EmbeddingToolRanker embeds new or changed catalogue tools incrementally. Therefore, “every later search embeds only the intent” is not true after a catalogue change. A disk-cache hit can also avoid recomputing the catalogue in a new process. Limit this statement to searches with an unchanged, warm catalogue, and document incremental updates.

Summary
Follow-up to #6435: the
tool_searchranker is measured on the real catalogue and reshaped around what the measurement showed. Full tables and method indocs/plans/jev-tool-search-baseline.md.Composio actions (66 labelled intents over 1,000 real actions across 9 toolkits, live Jev):
rank_tools_by_prompt(the integrations sub-agent's narrowing today)Needless answers on 31 tool-less requests: 26 with BM25, ≤1 with any Jev configuration. Family-then-decide runs at 1.3 s p50 through the proxy (two round trips, second stage concurrent).
What changed
tinytools-jevis transport-free upstream now (JevEvaluator), so thetinyjevclientwire moves here:openhuman_tinyhumans::jev::TinyJevEvaluatorbuilds oneChoice+needs_toolNoulperJevRequest, honours the request'sinstructions(the family stage asks "which group"), owns the credential, the client's retries and a per-evaluation deadline (6 s product default; raised from 3 s after measured proxy latency of 0.7–1.9 s p50).tinyjevclientpinned to84b3983(fix(response): size the probability-sum tolerance to the option count tinyjevclient#6, the probability-sum tolerance that was rejecting 3–8% of many-option answers).FamilyThenDecide(feat(jev): FamilyThenDecide strategy over the evaluator seam tinytools#19) scores a few points higher at a second round trip and stays available viaJevRankerConfig::with_strategy. No embedder, no Jev search: when the configured embedding provider isnone,TinyHumansJevRankererrors and the harness's BM25 bridge answers alone.EmbeddingToolRanker(agent/tinyagents/discovery/embedding_ranker.rs): cosine over the process's configured embedding provider (the same one memory recall uses), catalogue embeddings computed once in batches of 64 and cached in memory + on disk (<workspace>/cache/tool_search_embeddings.json, keyed by provider signature). It is the retriever insideJevRankerfor any family larger than one Jev choice (GitHub's 500 actions), lifting recall@20 from 70.5% to 86.8% (90.9% on Composio). BM25 remains the retriever when the process has no usable embedder (none).tool-search-benchgains--family,--embedding,--ranker embedding, a per-source (composio / core) split, retriever recall of the active retriever, and falls back to the signed-in TinyHumans session when no key is in the environment — exactly the product path.tests/fixtures/tool_search/intents.jsonl: 160 hand-written intents (66 Composio, 63 core, 31 none).vendor/tinyagents→ chore(vendor): tinytools to main (FamilyThenDecide merged) tinyagents#189 (main+vendor/tinytoolsonmainaa811fe, which includes Update quote in README.md #19).Notes
decodenow abstains whenneeds_tool < 0.5ornonewins; many core intents ("show me my todos") read as answerable without a tool. In the product those tools areDirectand never searched, so the Composio column is the onetool_searchis measured by.
