# desvela.dev: agentic web grade A

Score 51 (coverage 30 + breadth 6 + conformance 15); 4 standards observed across 3 of 9 steps; checked 2026-10-23T14:59:13Z. This grades the agent-facing files published at desvela.dev, not the organisation's products.

## Agent pre-flight & practical readiness

Preferred mode: `mcp` (fallback `llms_txt`). Call the MCP endpoint at https://registry.desvela.dev/mcp first. Do not scrape the HTML when a tool can answer.

Fetch: `POST https://registry.desvela.dev/mcp` POST a JSON-RPC tools/list, or server/discover on the 2026-07-28 revision, before reading HTML.

Practical readability: exa_parsable yes, markdown negotiation no, render `ssr_rich`, HTML quality `high`, tables 3 (31 rows), first content at byte 8792.

AI crawler posture: `open_to_all` · Assistant access: OpenAI `allowed`, Anthropic `allowed`, Google `allowed`, Perplexity `allowed`, Exa `allowed`.

Readiness subscores: reach 20/20, readability 20/30, capabilities 19/35, conformance 15/15, total 74/100, grade A.

## Rubric

+10 per lifecycle step with a standard observed, counting manifests that validate or that the probe rule for the standard recognises (a valid MCP server card counts for MCP; max 90); +3 per observed standard beyond the first two (max 15); conformance +15 (+10 with one manifest) minus 5 per agent-facing manifest with errors, never below 0 (security.txt is reported, not scored). Lifecycle grade: A+ >= 60, A >= 45, B >= 30, C >= 20, D >= 10. Strict 100-point composite (subscores.total_100 / subscores.grade_100): reach_and_policy (20) + readability (30) + capabilities (35) + conformance (15), where A+ >= 80, A >= 65, B >= 45, C >= 28, D >= 15.
