## Check Results

### API Design

- [warn] Schema coverage & depth — 2 of 11 public signatures use loose types (anyTypeRatio=0.182). Investigated: sdk 75%.
- [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] Self-service developer portal — Self-service signup at https://login.llamaindex.ai/?client_id=client_01K39WZXHMNYBR1MSJSYAQRVFT&redirect_uri=https%3A%2F%2Fapi.cloud.llamaindex.ai%2Fapi%2Fv1%2Fauth%2Fworkos%2Fcallback&state=eyJyZWRpcmVjdCI6ICJodHRwczovL2Nsb3VkLmxsYW1haW5kZXguYWkvIn0%3D&authorization_session_id=01KY9HENEBXDE5S8GND0400W0W; no free tier or sandbox language detected. Investigated: docs 100%.
- [pass] Changelog published — Newest official SDK activity 0 day(s) ago. Investigated: sdk 100%.
- [warn] Quickstart present — Quickstart page reachable (1 variants scanned starting at https://developers.api.llamaindex.ai/getting-started/) but no runnable code sample detected in HTML or .md variant. Investigated: docs 50%.
- [fail] Code samples in docs — No detectable code samples across 1 sampled docs pages. Investigated: docs 0%.
- [fail] Description completeness — 3/3 operations lack a description. Investigated: sdk 0%.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (websites/developers_llamaindex_ai, 59350 snippets). Investigated: docs 100%, cli 100%, sdk 92%.
- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/50 sampled pages return markdown). Investigated: docs 75%.
- [warn] llms.txt present, valid & comprehensive — No llms.txt directive found in HTML of any of 50 sampled pages. Investigated: docs 50%, sdk 0%.
- [warn] Crawlable / AEO — No sitemap discoverable via robots.txt or /sitemap.xml on the docs host. Investigated: wellknown 50%.

### Agent Understanding

- [warn] Agent-navigable, token-efficient docs — 12 of 50 pages have substantive content differences between markdown and HTML (avg 12% missing). 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 assessed pages (1 JS-rendered). Investigated: docs 0%.
- [skip] Machine-readable errors (RFC 9457) — No surface produced evidence for this capability in this run.
- [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

- [warn] Sandbox separation — No test-mode flag or sandbox environment is exposed. Investigated: sdk 50%.
- [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

LlamaIndex's API program shows genuine strength in agent discoverability — crawlability and docs reachability are solid foundations partners and agents can build on. However, the program has two critical gaps holding back partner outcomes: agents and developers lack the structured context and executable truth needed to integrate confidently, and the documentation surface is missing the completeness, code samples, and machine-readable signals that compress time to a first successful integration. Prioritize making the API surface fully understandable and runnable for both human partners and their AI agents, then close the remaining design and onboarding gaps to protect partner trust at scale.
