## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 86/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (94 of 98), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to skill-federation/skill-federation).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 1 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 49/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 427 tokens (~106/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 87/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 60% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

### 2026-07-27 (score 24)

First indexed and scored.

## MCP tools (4)

### `find_skills` (~83 tokens)

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.

Input parameters:

- `wishlist` (array, required): 1–10 wishes, each an ideal skill for the task

### `get_skill_bundle` (~46 tokens)

Fetch a confirmed match's bundle (SKILL.md + any extra files) for local install. Surface license/provenance/security_flags before installing.

Input parameters:

- `skill_id` (string, required)

### `report_selection` (~107 tokens)

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.

Input parameters:

- `chosen` (string, required): selected skill id, or the literal "None" if all candidates were rejected
- `query_id` (string, required)
- `rejected` (array): the other shown candidate ids (hard negatives)

### `emit_demand_pointer` (~191 tokens)

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.

Input parameters:

- `query_id` (string): optional; prepended to sketch as the trace if not already embedded
- `sketch` (string, required): condensed build spec per demand-sketch.md: "<query_id>: <minified-json>" (a STRING, not an object)
- `source` (string)
- `tags` (array)
- `wish` (string, required): the exact wish string you searched (the traceability anchor; required, non-empty)
