## Check Results

### API Design

- [pass] Auth declared & discoverable — authentication documented in the docs site at https://github.com/e2b-dev/e2b-cookbook. Investigated: spec 100%, docs 100%.
- [pass] Schema coverage & depth — 244/244 (100%) public params are fully typed (no any/**kwargs). Analyzer confirms all methods have a derivable input schema. Investigated: sdk 100%, spec 67%.
- [warn] Machine-readable, versioned contract — info.version="0.1.0" 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 50%.
- [pass] Example coverage — README is present and includes a runnable quickstart. Investigated: sdk 100%, spec 0%, docs 0%.

### Developer Experience

- [pass] Self-service developer portal — Signup page at https://e2b.dev/docs/mcp?utm_source=billboard&utm_medium=outdoor&utm_campaign=docker_2025&utm_content=ooh (CSR-rendered — body classifier inconclusive); free tier / sandbox documented in pricing/docs. Investigated: docs 100%.
- [pass] Quickstart present — Quickstart at https://e2b.dev/docs/quickstart has a runnable sample in the .md variant (https://e2b.dev/docs/quickstart.md). Investigated: docs 100%.
- [pass] Changelog published — changelog documented in the docs site at https://e2b.dev/docs/changelog. Investigated: spec 100%, docs 100%, sdk 100%.
- [warn] Description completeness — 33/126 operations lack a description. Investigated: sdk 74%, spec 0%.
- [fail] Code samples in docs — No detectable code samples across 20 sampled docs pages. Investigated: docs 0%.

### Agent Discovery

- [pass] Docs reachable, not hard auth-gated — All 50 sampled pages are publicly accessible. Investigated: docs 100%.
- [pass] Registry & SDK presence — Indexed on Context7 (websites/e2b_dev, 1782 snippets). Investigated: docs 100%, sdk 100%, cli 100%.
- [warn] llms.txt present, valid & comprehensive — llms.txt contains parseable links but doesn't fully follow the proposed structure: https://e2b.dev/docs/llms.txt: No blockquote summary found. Investigated: docs 92%, sdk 0%.
- [warn] Crawlable / AEO — Sitemap lastmod coverage 64% or newest entry older than 90 days. Investigated: wellknown 75%.

### Agent Understanding

- [pass] Machine-readable errors (RFC 9457) — 6 distinct 4xx/5xx response codes documented. Investigated: docs 100%, sdk 100%, spec 50%.
- [warn] Agent-navigable, token-efficient docs — 7 of 50 pages have minor content differences between markdown and HTML. Investigated: docs 94%.
- [pass] Docs structured data — JSON-LD Article markup on 15/15 assessed pages (100%) with dateModified present. Investigated: docs 100%.
- [warn] Description consistency across surfaces — Mean pairwise description similarity across 2 surfaces (docs, sdk) is 14% (threshold 35% for full credit).
- [fail] Operation purpose clarity — 0% of operations are agent-inferable. Investigated: spec 0%.
- [fail] Agent instructions file (AGENTS.md) — No AGENTS.md at the site root or /.well-known/. Investigated: wellknown 0%.

### 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 11 list endpoint(s). Investigated: docs 100%, spec 75%, sdk 13%.
- [pass] Sandbox separation — sandbox documented in the docs site at https://e2b.dev/docs/sandbox. Investigated: spec 100%, docs 100%, sdk 100%.
- [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

E2b's API Design and Agent Discovery are standout strengths — partners and agents can find and read the contract reliably. The critical gaps lie in Agent Understanding and Agent Usability: operations lack the semantic clarity and structured context that AI agents need to act autonomously, and there are no runnable collections or rate-limit signals to let partners safely validate real workflows. Closing these two areas should be the immediate priority to unlock self-serve partner integrations and agent-driven automation.
