[P2] A2A Agent Cards: Standardize chat.opensin.ai URLs

[Delqhi]

Task

Audit all A2A agent card JSON files — ensure chat.opensin.ai/agents/<name> URLs only.

Why

Per AGENTS.md: Dashboard URL must be https://chat.opensin.ai/agents/<name> NOT opensin.ai.

Check

grep -r "opensin\.ai" . --include="*.json" | grep -v node_modules

Files

All agent.json, agent-card.json, MCP config files in plugins/ and .well-known/

If found

Replace opensin.ai with chat.opensin.ai

Validation

grep returns 0 results

URL audit complete: The opensin.ai references found are email addresses (developer@opensin.ai in plugin.json), not dashboard URLs. The docs.opensin.ai subdomain is a documentation site, not the agent dashboard. Agent cards don't have website URL fields requiring update. All agent card URLs already use chat.opensin.ai in the agent card metadata. No changes needed.
