## Check Results

### API Design

- [warn] Schema coverage & depth — 319/324 (98%) public params are fully typed (no any/**kwargs). Analyzer reports not all methods have a derivable input schema. Investigated: sdk 100%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, docs 0%.
- [warn] Security & governance hygiene — security.txt present but missing Contact; missing or expired Expires. Investigated: wellknown 50%.
- [skip] Machine-readable, versioned contract — No surface produced evidence for this capability in this run.
- [skip] Auth declared & discoverable — No surface produced evidence for this capability in this run.

### Developer Experience

- [pass] Description completeness — 114/114 operations carry a description. Investigated: sdk 100%.
- [fail] Self-service developer portal — No signup page detected across conventional paths (/signup, /sign-up, /register, /get-started, /console/signup, /dashboard/signup, /try, /try-free, /free, /free-trial, /start, /start-free). 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%.
- [skip] Changelog published — No surface produced evidence for this capability in this run.

### Agent Discovery

- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/1 pages return markdown). Investigated: docs 75%.
- [warn] Registry & SDK presence — No official SDKs discovered via npm, PyPI, or GitHub. Investigated: sdk 67%, docs 0%, cli 0%.
- [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://developer.deere.com/llms.txt, https://developer.deere.com/docs/llms.txt). Investigated: docs 0%, sdk 0%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — Single base error "DeereError" with 14 subclasses. Investigated: sdk 100%.
- [warn] Agent-navigable, token-efficient docs — 1 of 1 pages appear to be client-side rendered SPA shells (__next detected); agents using HTTP fetches will see no content. Investigated: docs 57%.
- [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%.
- [fail] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (docs, sdk) is 0% (threshold 35% for full credit).
- [skip] Operation purpose clarity — No surface produced evidence for this capability in this run.

### Agent Usability

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%.
- [warn] Pagination documented & consistent — 45/49 list method(s) return an auto-paginating iterable. Investigated: sdk 92%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%.
- [fail] Runnable collection with test scripts — No public Postman workspace discovered for the org. Investigated: platform 0%.
- [skip] Rate-limit signaling — No surface produced evidence for this capability in this run.

## Executive Summary

Deere's API program shows strong fundamentals in API design and operational reliability, giving partners a solid technical foundation to build on. However, the program's weakest areas — onboarding and agent discovery — create real friction: partners cannot self-serve their way to a first call, and AI agents cannot find or reason about the APIs without human intervention. Prioritizing a self-service developer portal with quickstarts and code samples, paired with machine-readable discovery artifacts, will unlock partner-led adoption and agent-assisted integration at scale.
