fix(vision-search): accept limit as an alias for topK#1255anhtahaylove wants to merge 4 commits into
limit as an alias for topK#1255Conversation
vision-search and vision-embed are the only search-shaped functions that
name their result count `topK`; the other 23 (mem::search, smart-search,
lesson-recall, graph-query, facet-query, skill-match, ...) take `limit`.
An unknown key is dropped silently, so calling vision-search with `limit`
returns the default 10 results and looks like a hard cap.
Accept `topK ?? limit` in the function and in the REST layer, and note the
alias in the MCP tool schema. Existing topK callers are unaffected.
Measured on a 24-image store before the change: {"limit": 24} -> 10
results, {"topK": 24} -> 24. The silent truncation also skews retrieval
benchmarks, since anything ranked past 10 is invisible.

📝 WalkthroughWalkthroughVision search now accepts ChangesVision search limit alias
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The alias is accepted by the function and REST endpoint, but the MCP schema still does not expose limit as an input property, so MCP callers may be unable to discover or use the alias as intended. The new API test also uses local SDK fakes rather than the repository-standard SDK mock, leaving a bounded test reliability and maintenance risk. Merge should wait for these issues to be fixed or explicitly accepted by the owner. Sequence Diagram(s)sequenceDiagram

The MCP handler read only args.topK, so { limit: 2 } still reached
mem::vision-search with the default topK of 10 and the alias stopped at
the tool boundary. Resolve topK ?? limit there too, advertise limit in
the tool schema, and pin both in the registry test.

Good catch — fixed in e81352f. This was a real gap, not a nitpick: the alias worked over REST but died at the MCP boundary, which is exactly where I first hit the bug.
const topK = Math.max(1, Math.min(50, asNumber(args.topK, 10) ?? 10));So I also split the schema rather than mentioning the alias in topK: { type: "number", description: "Max results (default 10, max 50)" },
limit: { type: "number", description: "Alias for topK; topK wins when both are given" },Added a registry test pinning both properties, so a future edit that drops

@rohitg00 — ready for review. Fixes #1254. The PR accepts The MCP layer is worth calling out — CodeRabbit caught that my first commit missed it. The dispatcher in Tests: 42/42 across |
The REST trigger parses the result count itself, so the alias could regress there while the function-core tests stayed green. Removing `?? body["limit"]` now fails four of these six. Also pins the edges the core tests do not reach through this path: clamping to 50, and rejecting a zero or malformed limit rather than falling through to the default.

Fixes #1254.
mem::vision-searchandmem::vision-embedare the only search-shaped functions in the codebase that name their result counttopK. The other 23 —mem::search,mem::smart-search,mem::lesson-recall,mem::graph-query,mem::facet-query,mem::insight-search,mem::skill-matchand the rest — all readdata.limit.An unknown key is dropped silently, so a caller who reaches for the key they use everywhere else gets the default 10 results back with no error and no warning. It reads like a hard cap.
Measured on a 24-image store before this change:
{"queryText": "...", "limit": 24}{"queryText": "...", "topK": 24}{"queryText": "..."}What this changes
topK ?? limitin three places:src/functions/vision-search.ts— the function itself, so SDK and MCP callers are coveredsrc/triggers/api.ts— the REST endpoint, which parsed onlybody["topK"]src/mcp/tools-registry.ts— the tool schema now documents the aliastopKstill wins when both are present, so every existing caller behaves exactly as before.Why it is worth fixing rather than documenting
Silent truncation does not just cost a retry — it distorts measurements. Evaluating text→image retrieval on that 24-image store, top-5 accuracy reads 89% when the result set is quietly cut to 10, and 100% once the full set comes back. Anyone benchmarking vision-search with the wrong key under-measures it and may conclude the CLIP path is weaker than it is.
Tests
Two new cases in
test/vision-search.test.ts:accepts \limit` as an alias for topK— assertslimit: 2` returns 2 resultsprefers topK when both topK and limit are given— assertstopK: 1, limit: 3returns 1Both were confirmed to fail without the fix (reverting the
?? data?.limitalias turns the first one red), so they genuinely pin the behaviour rather than passing vacuously.Full suite:
30 failed | 1667 passed. Those 30 failures are present on a cleanmainat e04ba88 (30 failed | 1665 passed) and are unrelated to this change — the delta is exactly the 2 tests added here. Likewisenpx tsc --noEmitreports 5 pre-existing errors insrc/triggers/api.tson bothmainand this branch; none are in the lines touched.An alternative would be rejecting unknown keys with a 400 instead of aliasing. That is a breaking change for anyone currently passing stray keys, so I went with the compatible option — happy to switch if you would rather have it loud.
