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. How we score →

Supply Chain Security87
  • No malware found by supply-chain analysis.Pass
  • Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
  • No install/post-install scripts declared.Pass
  • Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency45
Schema Quality & AI Usability51
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 999 tokens (~249/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 4 exposed · ~734 tokens

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.

Tool Tokens
load_skill ~329

Load a community-vetted skill into your context on demand - like installing it mid-task. Reach for this when a task is in a domain a skill likely covers (tests, frontend/UI, an API/DB, infra, a named framework) and a proven recipe would beat improvising - most valuable in territory you are less sure of, or fast-moving stacks where your memory may be stale. You MUST pass `context` (your task + stack + constraints): it ranks candidates, fits them to your current repo, flags dependency mismatches, and keeps the load deliberate. Returns the best match (real SKILL.md + bundled scripts/refs materialized to a temp folder, used like an installed skill) PLUS the next-best candidates so you can switch. Always verify the loaded skill against your project before trusting it. For broad "current best practices across the field" tasks that span several skills, use synthesize_skills instead.

NameTypeReqDescription
contextstringyesREQUIRED. What you are actually doing + your stack + constraints/anti-patterns (e.g. "Next.js marketing page, no new deps, role-based locators"). Ranks candidates, fits them to your repo, and flags d…
idstring—An exact skill id from search_skillselion, e.g. "skill:owner/repo#slug".
querystring—What you need - task/skill keywords (e.g. "playwright e2e tests"). Required unless you pass an exact id.

No examples provided.

search_skillselion ~155

Search Skillselion, a curated directory of Claude Code agent skills, MCP servers and plugin marketplaces, ranked by real community signal (installs + GitHub stars). Use to browse trusted skills/MCPs/marketplaces for the task at hand (e.g. "postgres", "code review", "playwright"). To actually USE a skill, call load_skill (with an id from here, or directly with a query - it searches for you).

NameTypeReqDescription
limitinteger—Max results (default 8).
querystringyesWhat to search for - a tool, framework, task, or keyword.
typestring—Restrict to one listing type. Omit to search all.

No output schema declared.

No examples provided.

synthesize_skills ~178

Pull the BEST rules across the top matching community skills and merge them into one cross-source playbook - use for broad "how should I approach X / current best practices" tasks that span multiple skills, or when you want the field's combined guidance rather than one skill's. For a single specific skill (and its bundled scripts/files), use load_skill instead. Pass your task as `query` and your stack + constraints as `context` (required). Returns a deduped, provenance-tagged rule digest plus each source skill materialized on disk.
