PIC Standard: Provenance & Intent Contracts features

  • Action Proposal schema. Agents emit a JSON contract describing intent, impact, provenance and evidence before each tool call.
  • Deterministic evidence verification. SHA-256 resolvable artifacts are validated; unverifiable evidence blocks high-impact actions.
  • Fail-closed security model. If verification fails, the action is automatically rejected to prevent unsafe operations.
  • CLI and SDK integrations. Provides a command-line tool and drop-in integrations for LangGraph and MCP servers.
  • Cryptographic signing. Supports signing of contracts and API attestations for trusted provenance.
  • Risk classification. Allows agents to label impact classes such as money, privacy, compute or irreversible actions.

Syrin - Static Contract Analysis for MCP Servers features

  • First-class budget enforcement. Set dollar limits per agent; stop, warn or switch models when the budget is exceeded.
  • Budget-aware persistent memory. Four memory types with decay, import-rank and token-cost awareness, persisting across sessions.
  • Isolated sandbox execution. Run LLM-generated Python, Bash or JavaScript in subprocesses with timeouts and no shared state.
  • 72+ lifecycle hooks. Typed events fire on every LLM request, tool call, memory read, sandbox exec, etc., for observability.
  • Built-in guardrails. PII redaction, prompt-injection detection, content filtering, fact verification and output length limits.
  • Multi-agent orchestration. Swarm topologies and recursive sub-agent spawning share budget, memory and observability.
  • Agent identity & signing. Each agent has a cryptographic Ed25519 identity; messages are signed to prevent impersonation.
  • Token-Oriented Object Notation (TOON). Compact schema format reduces token usage on tool calls by ~40%.
