## Check Results

### API Design

- [pass] Schema coverage & depth — 4/4 (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%.
- [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] Self-service developer portal — Signup page at https://claude.ai/sign-up; no free-tier language detected in docs/pricing. Investigated: docs 100%.
- [pass] Changelog published — Newest official SDK activity 0 day(s) ago. Investigated: sdk 100%.
- [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%.
- [fail] Description completeness — 8/8 operations lack a description. Investigated: sdk 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/platform_claude_en, 18472 snippets). Investigated: docs 100%, sdk 100%, cli 0%.
- [warn] llms.txt present, valid & comprehensive — llms.txt found but only reachable via cross-host redirect (agents may not follow it); 1 failed to fetch. Investigated: docs 71%, sdk 0%.
- [warn] Docs reachable, not hard auth-gated — 1 of 50 sampled pages return 200 for non-existent URLs (soft 404). Investigated: docs 63%.
- [warn] Crawlable / AEO — Sitemap present (2699 entries) but carries no lastmod values. Investigated: wellknown 75%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — Single base error "ClaudeSDKError" with 5 subclasses. Investigated: sdk 100%.
- [warn] Agent-navigable, token-efficient docs — 31 of 50 sampled pages have content starting past 50% (worst 104%). Investigated: docs 75%.
- [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 sampled pages — likely a CSR-only docs site. Investigated: docs 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] 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

API Design and Agent Discovery are clear strengths — partners and agents can find and authenticate with these APIs without friction. The critical gaps are in Developer Experience and Agent Usability: there is no quickstart, code samples are absent, and descriptions are incomplete, meaning partners cannot get hands-on quickly without significant hand-holding. Compounding this, agents lack the structured context files, runnable collections, and idempotency guidance they need to integrate reliably and autonomously. Closing these gaps should be the immediate priority to enable self-serve partner onboarding and trustworthy agent-driven workflows.
