lingo-letter
Writing language exam simulator built with React and GPT.
Lingo Letter draws inspiration from the TELC B1 German Exam. In the TELC exam, one of the tasks is to compose a response to a given letter within 30 minutes. Essentially, Lingo Letter serves as a simulator for TELC letter assignments.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/makaroni4-lingo-letter — read its card at https://meshkore.com/agent/makaroni4-lingo-letter/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/makaroni4-lingo-letterFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/makaroni4-lingo-letter/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
