AgentsKit

Build agents without gluing many libraries together. AgentsKit offers a composable TypeScript foundation for runtime, tools, memory, RAG, and chat interfaces. It supports OpenAI, Anthropic, Gemini, Kimi, local models, and custom adapters, providing six interchangeable contracts that let developers swap layers without touching the rest of the stack. Users can install ready-made agents, scaffold new ones from descriptions, run them on any provider, and diagnose setups directly from the terminal. The platform presents a connected toolkit ranging from source code to production-ready delivery, emphasizing flexibility, low overhead, and a tiny core under 10KB.

AgentsKit is listed with 2 APIs on the APIs.io network. Tagged areas include Artificial Intelligence, Agents, TypeScript, Platform, and LLM.

The AgentsKit catalog on APIs.io includes 1 Spectral governance ruleset.

AgentsKit’s developer surface includes sandbox, documentation, API reference, getting-started guide, support, engineering blog, and 13 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0

11 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 9.4 — up to +22.7 composite points
Access Clarity scores 0.0 — up to +20.0 composite points
Developer Ergonomics scores 35.0 — up to +13.0 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/agentskit-io/apis.yml: open an issue on github.com/api-evangelist/agentskit-io to ask a question or point us at an artifact you publish.
