Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Legal Reasoning
Formal frameworks for legal analysis, argumentation, normative reasoning, and their intersection with formal verification and AI governance.
Routing
- USE FOR: Legal reasoning formalization — statutory interpretation, case-based reasoning, argumentation frameworks, defeasible rules, deontic norms, regulatory compliance, and their connection to provenance chains, governance structures, and formal verification for legal-adjacent AI systems.
- DO NOT USE FOR: formalising those legal models in Lean (use @lean-applied-reasoning); deontic reasoning specifically (use @ai-causal-deontic); security policy (use @applied-data-information-security).
- TRIGGERS: statutory interpretation, case-based reasoning, argumentation framework, defeasible rule, deontic norm, legal reasoning, regulatory.
Workflow
- Classify the legal task: statutory interpretation, case-based reasoning, argumentation, or deontic-norm modelling.
- Pick the matching framework (ASPIC+, Carneades, defeasible-logic, deontic-action) from the body.
- Apply the framework; document the argument structure + defeaters.
- Hand off: to
@ai-causal-deonticfor deontic-logic encoding, to@lean-applied-reasoningfor Lean formalisation, to@lean-zettelkasten.
Recovery & STOP
- STOP if the question is about pure deontic logic — delegate to
@ai-causal-deontic. - STOP if the legal regime is jurisdiction-specific and not in the body — escalate to
@research-council. - STOP if security/privacy policy dominates — delegate to
@applied-data-information-security.
