Smarthr's API program shows strength in basic contract structure, but agent understanding and agent usability are critically underdeveloped — partners and their AI agents cannot reliably parse errors, understand operation intent, or run safe end-to-end workflows. The most urgent priorities are making the API surface interpretable and executable for agents (structured error semantics, operation clarity, and runnable examples), then closing the discoverability and onboarding gaps that slow every new partner's first integration.

API DesignA clean, typed, well-governed API contract agents can reason about1 pass2 warn2 fail61C
SignalPointsFindingsRationale
warnMachine-readable, versioned contractvia spec18.8/25info.version="0.0.1" set but no versioning scheme (URL / header / media type) detected. Investigated: spec 75%, docs 50%.A current OpenAPI version with a declared versioning scheme lets agents reason about the contract.
warnSchema coverage & depthvia spec16.7/2592% of operations have documented schemas (target 95%+). Investigated: spec 67%, sdk 0%.Typed, complete request/response schemas are what make agent function-calling possible.
passSecurity & governance hygienevia spec15/15No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 100%.No leaked secrets, no critical lint violations, no OWASP API Top-10 spec smells, and a published vulnerability-disclosure channel.
failAuth declared & discoverablevia spec0/25No securitySchemes declared. Investigated: spec 0%, docs 0%.Agents can only authenticate when auth is declared, scoped, and discoverable.
failExample coveragevia spec0/100% example coverage. Investigated: spec 0%, docs 0%, sdk 0%.Examples carry shape semantics schemas under-specify — for humans and agents alike.
Developer ExperienceThe context both developers and agents need to integrate fast — onboarding, code samples, complete descriptions and worked examples2 pass0 warn3 fail56D
SignalPointsFindingsRationale
passSelf-service developer portalvia docs29/29Self-service signup at https://smarthr.jp/signup/; free tier / sandbox documented. Investigated: docs 100%.Self-serve key/account creation is the fast first call for partners, with no sales gate.
passChangelog publishedvia sdk13/13Newest official SDK activity 0 day(s) ago. Investigated: sdk 100%, spec 0%, docs 0%.A published changelog lets partners track changes without surprise.
failQuickstart presentvia docs0/25No quickstart/getting-started page found at the conventional paths. Investigated: docs 0%.A quickstart is the fastest path from landing page to first successful call.
failCode samples in docsvia docs0/18No detectable code samples across 1 sampled docs pages. Investigated: docs 0%.Multi-language samples shorten time-to-first-call.
failDescription completenessvia spec0/1532% description completeness. Investigated: spec 0%.Complete descriptions are the context humans and agents need to use endpoints.
Agent DiscoveryPartners and their agents can find your APIs — llms.txt, registries, crawlable and reachable docs1 pass2 warn1 fail65C
SignalPointsFindingsRationale
passRegistry & SDK presencevia docs28/28Indexed on Context7 (websites/support_smarthr_jp_ja, 1420 snippets). Investigated: docs 100%, sdk 75%, cli 0%.Listing in MCP registries and publishing SDKs puts the API where agents and their tooling look.
warnDocs reachable, not hard auth-gatedvia docs22.5/30Server ignores Accept: text/markdown header (0/1 pages return markdown). Investigated: docs 75%.Agents can only index and fetch docs they can reach — past auth gates and over correct HTTP semantics.
warnCrawlable / AEOvia wellknown6/12No sitemap discoverable via robots.txt or /sitemap.xml on the docs host. Investigated: wellknown 50%.Bots allowed plus a fresh sitemap make docs findable by agent crawlers.
failllms.txt present, valid & comprehensivevia docs0/30No llms.txt found at any candidate location (https://developer.smarthr.jp/llms.txt, https://developer.smarthr.jp/docs/llms.txt). Investigated: docs 0%.A valid, comprehensive llms.txt is the machine-readable entry point for agents.
Agent UnderstandingAgents can correctly interpret your APIs — machine-readable errors, consistent descriptions, structured data, parseable docs0 pass1 warn4 fail45F
SignalPointsFindingsRationale
warnAgent-navigable, token-efficient docsvia docs17.3/22No pages support .md URLs (0/1 tested). Investigated: docs 79%.Server-rendered, clean, small-footprint docs are what an agent can cheaply fetch and parse correctly.
failMachine-readable errors (RFC 9457)via spec0/28No 4xx/5xx response codes (or default error response) documented anywhere in the spec. Investigated: spec 0%, docs 0%.RFC 9457 problem details and a documented error-code inventory let agents parse failures without burning tokens.
failOperation purpose clarityvia spec0/258% of operations are agent-inferable. Investigated: spec 0%.Agents select the right endpoint from its summary + operationId; clear, named operations make tool-selection reliable — the strongest driver of correct tool choice.
failAgent instructions file (AGENTS.md)via wellknown0/10No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.An AGENTS.md gives coding agents explicit setup, auth, and usage instructions to interpret and operate the API — beyond llms.txt's link index.
failDocs structured datavia docs0/8Neither JSON-LD nor OpenGraph/meta tags detected across 1 assessed pages (1 JS-rendered). Investigated: docs 0%.Structured data (JSON-LD/schema.org) on docs pages gives agents an unambiguous parse target and is what answer engines cite. Detected on the JS-rendered head (Firecrawl) for a bounded page budget, so JS-injected JSON-LD is now caught; pages we can't render are excluded rather than failed.
naDescription consistency across surfaces—/7Only 0 surface description(s) with ≥6 tokens available; need at least 2 to compare.Every surface tells the same story about what the product is.
Agent UsabilityAgents have the context to use your APIs reliably, not just find them1 pass0 warn4 fail46F
SignalPointsFindingsRationale
passPagination documented & consistentvia spec22/22Pagination params detected on 26 list endpoint(s). Investigated: spec 100%, docs 100%.Consistent, documented pagination lets agents traverse collections.
failIdempotency documentedvia spec0/270% of mutating operations document idempotency. Investigated: spec 0%, docs 0%.Documented idempotency lets agents retry safely.
failRate-limit signalingvia spec0/22No rate-limit response headers documented. Investigated: spec 0%, docs 0%.Machine-readable rate-limit headers let agents throttle adaptively.
failSandbox separationvia spec0/20No sandbox/test server declared across 1 server entries; no test-key prefixes documented. Investigated: spec 0%, docs 0%.An isolated environment lets agents exercise destructive operations safely.
failRunnable collection with test scriptsvia platform0/9No public Postman workspace discovered for the org. Investigated: platform 0%.A public, maintained collection with assertions is runnable truth agents validate against.
