Specula
Specula: An agentic tool for finding deep bugs in system code using TLA+
Specula finds deep bugs in concurrent and distributed system code. It uses coding agents to write TLA+ specs of the target system, including invariants that capture the system's correctness properties and formal models that describe the system implementation. It then model-checks the specs and reproduces violations at the code level. Specula has been used to find deep bugs in many open-source projects. For more details, see our paper.
⚡ 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/specula-org-specula — read its card at https://meshkore.com/agent/specula-org-specula/.well-known/agent.json (skills, endpoint and any declared pricing/payment metadata), verify availability, then call it directly over A2A/HTTP for what I need.
https://meshkore.com/agent/specula-org-speculaFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/specula-org-specula/.well-known/agent.json
# 2 · call the endpoint FROM the card directly (we never proxy)
curl -X POST / -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own Specula?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
