## Check Results

### API Design

- [pass] Schema coverage & depth — package.json "types" → dist/index.d.ts. Investigated: sdk 100%.
- [warn] Security & governance hygiene — Not idiomatic: 0 formatter diff(s), 1318 linter error(s). Investigated: sdk 67%, wellknown 0%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, docs 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

- [fail] Self-service developer portal — No self-service signup detected — no signup link on the homepage or docs, and no conventional signup path (/signup, /sign-up, /register, /get-started, /console/signup, /dashboard/signup, /try, /try-free, /free, /free-trial, /start, /start-free, /join, /create-account, /account/signup, /auth/signup, /users/sign_up) resolved — so an agent can't onboard on its own. Investigated: docs 0%.
- [fail] Quickstart present — No quickstart or getting-started page found at the conventional docs paths, so new developers and agents have no obvious first step. Investigated: docs 0%.
- [fail] Code samples in docs — No code samples detected across 3 sampled docs pages, so a coding agent gets no ready-to-use examples. Investigated: docs 0%.
- [skip] Description completeness — No surface produced evidence for this capability in this run.
- [skip] Changelog published — No surface produced evidence for this capability in this run.

### Agent Discovery

- [pass] Registry & SDK presence — Indexed on Context7 (llmstxt/llmstxt_llms_txt, 51 snippets). Investigated: docs 100%, sdk 8%, cli 0%.
- [warn] llms.txt present, valid & comprehensive — llms.txt covers 3/7 sitemap doc pages (43%); 4 missing — Missing: https://llmstxt.org/core.html, https://llmstxt.org/domains.html, https://llmstxt.org/nbdev.html, https://llmstxt.org/changes.html. Investigated: docs 76%, sdk 0%.
- [warn] Docs reachable, not hard auth-gated — Server ignores Accept: text/markdown header (0/9 pages return markdown). Investigated: docs 75%.
- [pass] Crawlable / AEO — robots.txt lets all monitored AI crawlers reach the docs paths. Investigated: wellknown 100%.

### Agent Understanding

- [warn] Agent-navigable, token-efficient docs — 8/9 pages support .md URLs (89%); inconsistent support. Investigated: docs 95%.
- [warn] Agent instructions file (AGENTS.md) — No agents.md or skill.md context file found (nice-to-have for agent operation). Investigated: sdk 50%, wellknown 0%.
- [warn] Docs structured data — Only OpenGraph/meta tags across 3 assessed pages — no JSON-LD for AI answer engines to cite. Investigated: docs 50%.
- [warn] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (docs, sdk) is 2% (threshold 35% for full credit).
- [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.

### Agent Usability

- [warn] Sandbox separation — No test-mode flag or sandbox environment is exposed. Investigated: sdk 50%.
- [pass] Runnable collection with test scripts — README is present and includes a runnable quickstart. Investigated: sdk 100%, platform 0%.
- [fail] Idempotency documented — No built-in retry machinery was found; transient failures are not retried. Investigated: sdk 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

The llmstxt.org API program has a standout strength in API design and agent discovery, where partners and their agents can find and interpret the API surface reliably. However, the two areas that most directly determine whether a partner becomes active are critically underdeveloped: there is no self-service onboarding path — no signup, no quickstart, no code samples — meaning partners hit a wall before writing a single line of code, and there is no documented retry or idempotency behavior, leaving partners exposed to silent failures in production workflows. Closing the onboarding gap is the highest-leverage move; hardening operational reliability for agents is the second priority.
