## Cheapest next steps

1. AGENTS.md: instructions for coding agents working on or with the site (https://agenticweb.wiki/protocols/agents-md/)
2. security.txt (RFC 9116): RFC 9116 contact and expiry, read by agents and people (https://www.rfc-editor.org/rfc/rfc9116)

## 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). A+ >= 60, A >= 45, B >= 30, C >= 20, D >= 10.
