# llms.txt — agentjson.org # Canonical agent-guidance surface (text/plain). Not a glyph catchall. # Updated: 2026-08-06 # Sources: /.well-known/agent.json + /.well-known/agent-discovery.json > agentjson.org is the constellation schema registry and bootstrap node for the velastra-codex agent mesh. ## Identity - Name: agentjson.org - Role: schema_registry - Protocol: FCS-4.0 - Constellation: velastra-codex - Description: Constellation schema registry and bootstrap node for the velastra-codex agent mesh - Manifest updated: 2026-04-30 ## Primary discovery (authoritative) - Agent manifest: https://agentjson.org/.well-known/agent.json - Agent discovery: https://agentjson.org/.well-known/agent-discovery.json - Bootstrap: https://agentjson.org/.well-known/agent-bootstrap.json - Constellation: https://agentjson.org/.well-known/constellation.json (also /constellation.json) - ABF feed: https://agentjson.org/.well-known/abf.json (application/json) - Sitemap: https://agentjson.org/sitemap.xml - Discovery sitemap: https://agentjson.org/sitemap-discovery.xml ## Feeds - type=abf → https://agentjson.org/.well-known/abf.json ## Optional protocol surfaces - Invocation registry: https://agentjson.org/invocation-registry.json - Trust verify: https://agentjson.org/verify?domain={domain} - Invoke demos: https://agentjson.org/invoke/* ## Canonical paths for this document - https://agentjson.org/llms.txt - https://agentjson.org/.well-known/llms.txt - Both MUST return the same text/plain body. ## Explicit non-advertisements - /.well-known/ai.txt and /ai.txt — NOT an authoritative AI-policy document. Not advertised in sitemaps or discovery until a real policy is defined and approved. Honest response is non-discovery (404), not a glyph-catchall JSON 200. - Glyph-resonance JSON responses are non-canonical. Do not treat them as llms/ai policy. ## How to use 1. Fetch /.well-known/agent.json for identity. 2. Fetch /.well-known/agent-discovery.json for protocol family + feeds. 3. Use this llms.txt as the human/agent readable map of those surfaces.
