The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
emit_demand_pointer ~191
Record a missing capability on a MISS — a wish that returned zero candidates (empty), OR one where you rejected every candidate (the rejection reasoning reveals the gap). Pass the searched `wish` string plus a `sketch` STRING built per demand-sketch.md (a single-line JSON of purpose/inputs/outputs/operations/domain_vocab/section_sketch, prefixed with the query_id). Capability-level abstraction only — never plan/brief/output/data.
| Name | Type | Req | Description |
|---|---|---|---|
| query_id | string | – | optional; prepended to sketch as the trace if not already embedded |
| sketch | string | yes | condensed build spec per demand-sketch.md: "<query_id>: <minified-json>" (a STRING, not an object) |
| source | string | – | – |
| tags | array | – | – |
| wish | string | yes | the exact wish string you searched (the traceability anchor; required, non-empty) |
No output schema declared.
No examples provided.
find_skills ~83
Search a federated catalog of vetted agent skills for a privacy-abstracted wish-list. Returns up to k recall candidates per wish (the client agent makes the final pick). Send only abstracted wishes — never the plan, brief, outputs, or any tenant data.
| Name | Type | Req | Description |
|---|---|---|---|
| wishlist | array | yes | 1–10 wishes, each an ideal skill for the task |
No output schema declared.
No examples provided.
get_skill_bundle ~46
Fetch a confirmed match's bundle (SKILL.md + any extra files) for local install. Surface license/provenance/security_flags before installing.
| Name | Type | Req | Description |
|---|---|---|---|
| skill_id | string | yes | – |
No output schema declared.
No examples provided.
report_selection ~107
Report one wish's agentic-selection outcome. chosen = the selected skill id, or the literal string "None" when every candidate was rejected (a retrieval-quality label, complementary to a demand pointer — not a substitute for it). rejected = the other shown candidate ids.
| Name | Type | Req | Description |
|---|---|---|---|
| chosen | string | yes | selected skill id, or the literal "None" if all candidates were rejected |
| query_id | string | yes | – |
| rejected | array | – | the other shown candidate ids (hard negatives) |
No output schema declared.
No examples provided.
