## Check Results

### API Design

- [warn] Schema coverage & depth — 37 of 264 public signatures use loose types (anyTypeRatio=0.140). Investigated: sdk 82%, spec 67%.
- [warn] Machine-readable, versioned contract — info.version="0.0.1" set but no versioning scheme (URL / header / media type) detected. Investigated: spec 75%, docs 50%.
- [pass] Security & governance hygiene — No credential-shaped strings detected in spec. Investigated: spec 100%, wellknown 100%.
- [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] Changelog published — Newest official SDK activity 0 day(s) ago. Investigated: sdk 100%, spec 0%, docs 0%.
- [warn] Description completeness — 94/115 operations carry a description. Investigated: sdk 82%, spec 0%.
- [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 7 sampled docs pages. Investigated: docs 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (bodaay/huggingfacemodeldownloader, 339 snippets). Investigated: docs 100%, sdk 100%, mcp 100%, cli 0%, wellknown 0%.
- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/39 pages return markdown); 39 rate-limited (HTTP 429). Investigated: docs 75%.
- [warn] Crawlable / AEO — Sitemap present (7 entries) but carries no lastmod values. Investigated: wellknown 75%.
- [fail] llms.txt present, valid & comprehensive — No llms.txt found at any candidate location (https://huggingface.co/docs/llms.txt, https://huggingface.co/llms.txt). Investigated: docs 0%, sdk 0%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 4 distinct 4xx/5xx response codes documented. Investigated: docs 100%, spec 50%.
- [warn] Agent-navigable, token-efficient docs — No pages support .md URLs (0/39 tested). Investigated: docs 71%.
- [warn] Operation purpose clarity — 0% of operations are agent-inferable. Investigated: spec 50%.
- [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 3 assessed pages (3 JS-rendered). Investigated: docs 0%.
- [fail] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (spec, sdk) is 0% (threshold 35% for full credit).

### Agent Usability

- [pass] Idempotency documented — Built-in retry machinery is present (grep-derived). Investigated: sdk 100%, spec 0%, docs 0%.
- [pass] Pagination documented & consistent — Pagination params detected on 36 list endpoint(s). Investigated: spec 100%, docs 100%.
- [pass] Sandbox separation — Sandbox environments are exposed (sandbox). Investigated: sdk 100%, spec 0%, docs 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

Hugging Face's API design and contract quality are strong, giving partners a solid technical foundation to build on. However, the partner program is held back by two critical gaps: developer onboarding is entirely self-directed with no portal, quickstart, or code samples to accelerate a first successful call, and the documentation surface is invisible to AI agents — no llms.txt, no agent instructions file, no structured data, and inconsistent descriptions mean agents cannot discover, parse, or act on the APIs without guessing. Prioritize creating a self-service onboarding experience with runnable examples first, then systematically layer in agent-readable signals so partners and their AI tools can integrate without friction or human intervention.
