## Check Results

### API Design

- [pass] Schema coverage & depth — 12/12 (100%) public params are fully typed (no any/**kwargs). Analyzer confirms 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%.
- [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

- [pass] Description completeness — 11/11 operations carry a description. Investigated: sdk 100%.
- [pass] Changelog published — Newest official SDK activity 65 day(s) ago. Investigated: sdk 100%.
- [warn] Quickstart present — Quickstart page reachable (12 variants scanned starting at https://developers.adp.com/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%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/developers_adp, 11620 snippets). Investigated: docs 100%, sdk 67%, cli 0%.
- [warn] Docs reachable, not hard auth-gated — 1 of 1 pages return 200 for non-existent URLs (soft 404). Investigated: docs 50%.
- [warn] llms.txt present, valid & comprehensive — No llms.txt found at any candidate location (https://developers.adp.com/llms.txt, https://developers.adp.com/docs/llms.txt). Investigated: docs 33%, sdk 0%.
- [warn] Crawlable / AEO — Sitemap present (0 entries) but carries no lastmod values. Investigated: wellknown 75%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — Single base error "ADPError" with 10 subclasses. Investigated: sdk 100%.
- [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 57%.
- [warn] Docs structured data — OpenGraph/meta tags only across 1 assessed pages — no JSON-LD for answer engines to cite. Investigated: docs 50%.
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.
- [skip] Operation purpose clarity — No surface produced evidence for this capability in this run.
- [skip] Description consistency across surfaces — Only 0 surface description(s) with ≥6 tokens available; need at least 2 to compare.

### Agent Usability

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%.
- [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.
- [skip] Pagination documented & consistent — No surface produced evidence for this capability in this run.

## Executive Summary

ADP's API program shows strength in agent discoverability and structured data, but two areas demand immediate attention: developer onboarding is the weakest link — partners lack a self-service portal and in-context code samples, meaning they cannot get hands-on without a sales conversation — and the program is missing both the agent instruction context and runnable, test-backed collections that AI-powered integrations depend on. Prioritize closing the onboarding gap and establishing a runnable source of truth first, then layer in agent-specific artifacts to make the program ready for partner-built AI workflows.
