## Check Results

### API Design

- [warn] Machine-readable, versioned contract — info.version="2.0.0" set but no versioning scheme (URL / header / media type) detected. Investigated: spec 88%, docs 75%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 0%.
- [warn] Auth declared & discoverable — No securitySchemes declared. Investigated: docs 50%, spec 25%.
- [pass] Example coverage — 0% example coverage. Investigated: spec 100%, sdk 100%, docs 0%.

### Developer Experience

- [pass] Description completeness — 50% description completeness. Investigated: spec 100%, sdk 94%.
- [pass] Changelog published — Newest official SDK activity 1 day(s) ago. Investigated: sdk 100%, spec 0%, docs 0%.
- [fail] Self-service developer portal — No self-service signup detected: no signup link found on the homepage or docs, and no conventional signup path (/signup, /sign-up, /register, /get-started, /console/signup, /dashboard/signup, /try, /try-free, /free, /free-trial, /start, /start-free, /join, /create-account, /account/signup, /auth/signup, /users/sign_up) resolved. Investigated: docs 0%.
- [fail] Quickstart present — No quickstart/getting-started page found at the conventional paths. Investigated: docs 0%.
- [fail] Code samples in docs — No detectable code samples across 1 sampled docs pages. Investigated: docs 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/arrow-kt_io_learn, 750 snippets). Investigated: docs 100%, sdk 100%, cli 0%.
- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/1 pages return markdown). Investigated: docs 75%.
- [warn] Crawlable / AEO — No sitemap discoverable via robots.txt or /sitemap.xml on the docs host. Investigated: wellknown 50%.
- [fail] llms.txt present, valid & comprehensive — No llms.txt found at any candidate location (https://developers.arrow.com/api/llms.txt, https://developers.arrow.com/llms.txt, https://developers.arrow.com/docs/llms.txt). Investigated: docs 0%, sdk 0%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — No 4xx/5xx response codes (or default error response) documented anywhere in the spec. Investigated: docs 100%, spec 50%, sdk 0%.
- [warn] Operation purpose clarity — 76% of operations are agent-inferable (target 90%+). Investigated: spec 75%.
- [warn] Agent-navigable, token-efficient docs — No pages support .md URLs (0/1 tested). Investigated: docs 71%.
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.
- [fail] Docs structured data — Neither JSON-LD nor OpenGraph/meta tags detected across 1 assessed pages (1 JS-rendered). Investigated: docs 0%.
- [skip] Description consistency across surfaces — Only 1 surface description(s) with ≥6 tokens available; need at least 2 to compare.

### Agent Usability

- [pass] Pagination documented & consistent — Pagination params detected on 7 list endpoint(s). Investigated: spec 100%, docs 100%.
- [warn] Sandbox separation — No test-mode flag or sandbox environment is exposed. Investigated: sdk 50%, spec 0%, docs 0%.
- [fail] Idempotency documented — 0% of mutating operations document idempotency. Investigated: spec 0%, docs 0%, sdk 0%.
- [fail] Rate-limit signaling — No rate-limit response headers documented. Investigated: spec 0%, docs 0%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.

## Executive Summary

Arrow's API design and security foundations are strong, giving partners a reliable contract to build against. However, the partner onboarding experience is the most urgent gap: there is no self-service portal, no quickstart, and no code samples, meaning partners cannot get hands-on without a sales conversation — a critical barrier to program growth. Agent discoverability and usability are also materially weak, with missing machine-readable context files and no runnable collections, leaving AI agents unable to find, understand, or safely execute Arrow's APIs. Prioritize building a self-service onboarding surface first, then layer in agent-readiness signals to unlock both human partners and their AI tooling.
