## Check Results

### API Design

- [pass] Schema coverage & depth — .d.ts present on disk but not declared in package.json. Investigated: sdk 100%.
- [pass] Auth declared & discoverable — The MCP server at https://nexez.app/mcp accepts unauthenticated requests, so an agent knows it needs no credentials. Investigated: mcp 100%.
- [pass] Security & governance hygiene — Code is formatter-clean with zero linter errors and zero style warnings. Investigated: sdk 100%, wellknown 0%.
- [pass] Example coverage — Code samples appear on 2 of 20 sampled docs pages across 1 language(s), but broader multi-language coverage is missing. Investigated: docs 100%, sdk 100%.
- [skip] Machine-readable, versioned contract — No surface produced evidence for this capability in this run.

### Developer Experience

- [pass] Self-service developer portal — Signup page at https://exe.dev/auth?plan=personal&source=public_nav (client-rendered, so its contents couldn't be classified); free tier or sandbox is documented in pricing/docs. Investigated: docs 100%.
- [pass] Quickstart present — Quickstart at https://exe.dev/docs/search?q=quickstart&from=%2Fdocs%2Fwhat-is-exe%2Fquickstart includes a runnable first-call code sample. Investigated: docs 100%.
- [pass] Code samples in docs — Code samples appear on 2 of 20 sampled docs pages across 1 language(s), but broader multi-language coverage is missing. Investigated: docs 100%.
- [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] llms.txt present, valid & comprehensive — llms.txt found at https://exe.dev/llms.txt. Investigated: docs 100%, sdk 0%.
- [pass] Docs reachable, not hard auth-gated — All 1 pages are publicly accessible. Investigated: docs 100%.
- [pass] Registry & SDK presence — Indexed on Context7 (websites/exe_dev, 1069 snippets). Investigated: docs 100%, cli 100%, sdk 50%, wellknown 50%, mcp 0%.
- [warn] Crawlable / AEO — Sitemap has 2 entries but no lastmod values, so crawlers can't tell what changed recently. Investigated: wellknown 75%.

### Agent Understanding

- [pass] Agent-navigable, token-efficient docs — All 1 pages contain server-rendered content. Investigated: docs 100%.
- [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%.
- [fail] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (docs, sdk) is 0% (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

Exe's API program shows strong discoverability — partners and agents can find your APIs without friction. The two areas that need urgent attention are description consistency and retry/idempotency support. When your SDK and docs describe the same endpoints in entirely different language, AI agents cannot reliably map intent to the right call, and integration breaks silently. Layered on top, the absence of retry machinery means transient failures surface as hard errors for partners — prioritizing these two gaps will materially improve integration success rates and partner trust.
