## Check Results

### API Design

- [pass] Schema coverage & depth — 78/78 enums are named types (not bare strings). Investigated: sdk 100%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, docs 0%.
- [fail] Security & governance hygiene — No security.txt at /.well-known/security.txt or /security.txt. Investigated: wellknown 0%.
- [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

- [warn] Quickstart present — Quickstart page reachable (24 variants scanned starting at https://developer.workday.com/documentation/quickstart) but no runnable code sample detected in HTML or .md variant. Investigated: docs 50%.
- [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] Code samples in docs — No detectable code samples across 1 sampled docs pages. Investigated: docs 0%.
- [fail] Description completeness — 8/8 operations lack a description. Investigated: sdk 0%.
- [fail] Changelog published — Official SDKs stale: newest activity 426 days ago. Investigated: sdk 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/canvas_workdaydesign_guidelines_color, 7 snippets). Investigated: docs 100%, sdk 50%, cli 0%.
- [warn] llms.txt present, valid & comprehensive — No llms.txt directive found in HTML of any of 1 pages. Investigated: docs 60%, sdk 0%.
- [warn] Docs reachable, not hard auth-gated — 1 of 1 pages return 200 for non-existent URLs (soft 404). Investigated: docs 50%.
- [warn] Crawlable / AEO — Sitemap present (0 entries) but carries no lastmod values. Investigated: wellknown 75%.

### Agent Understanding

- [warn] Agent-navigable, token-efficient docs — 1 of 1 pages appear to be client-side rendered SPA shells (root detected); agents using HTTP fetches will see no content. Investigated: docs 63%.
- [fail] Machine-readable errors (RFC 9457) — No single common SDK base error class was found; errors do not share one root. Investigated: sdk 0%.
- [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] Operation purpose clarity — No surface produced evidence for this capability in this run.
- [skip] Description consistency across surfaces — Only 1 surface description(s) with ≥6 tokens available; need at least 2 to compare.

### Agent Usability

- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%.
- [fail] Idempotency documented — No built-in retry machinery was found; transient failures are not retried. Investigated: sdk 0%.
- [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.
- [skip] Pagination documented & consistent — No surface produced evidence for this capability in this run.

## Executive Summary

Workday's API program shows solid discoverability fundamentals, but partners and their AI agents face critical friction in two areas: developer experience and agent understanding. There is no self-service portal, no changelog, no code samples, and no machine-readable error or context signals — meaning partners cannot onboard without a sales conversation, and agents cannot reliably parse or act on the API surface. The highest-priority investments are establishing a self-service documentation and onboarding layer and making the API surface fully machine-readable and agent-actionable.
