fly.io agentic web readiness
A+ Manifest validity: 89% (8/9 valid, 2 errors, 5 warnings) · Surface score 65 (coverage 40 + breadth 15 + conformance 10). 10 standards observed across 4 of 9 steps; 9 manifests present, 2 errors, 5 warnings. Checked 2026-10-23 14:55:37 UTC. This grades the agent-facing files published at fly.io, not the organisation's products.

Agent pre-flight & practical readiness
Preferred mode: mcp (fallback openapi). Call the MCP endpoint at https://sprites.dev/mcp first. Do not scrape the HTML when a tool can answer.
Fetch: POST https://sprites.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 yes, render markdown_native, HTML quality high, first content at byte 0.
AI crawler posture: open_to_all · Assistant access: OpenAI partial, Anthropic partial, Google partial, Perplexity partial, Exa partial.
Readiness subscores: reach 20/20, readability 30/30, capabilities 35/35, conformance 10/15, total 95/100, grade A+.
How the grade is made
+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. Errors are specification violations; warnings are best-practice gaps. Only public paths are fetched, without credentials, so standards that need a login (skipped in the probe) are not counted either way. The same report is the validate_manifest tool on the MCP server.
