AgentAssert Type-C kernel — formal behavioral contracts for AI agent harnesses. Provider-blind, transport-blind runtime enforcement.
Project description
agentassert-typec-core
Formal behavioral contract kernel. Provider-blind, transport-blind.
This is the core engine — zero LLM deps, zero HTTP deps. Every adapter (proxy, SDK, hook) imports this.
Features
- 7 Process Contract Operators — tool_blocklist, tool_allowlist, must_state, must_precede, context_budget, process_drift, judge_predicate
- ContractSpec DSL — YAML-based,
dsl_version: "0.4"for full Type-C,dsl_version: "0.3"for ABC compatibility - JSD Drift Tracker — Welford-style incremental (O(1) per update), frozen baseline at window boundary
- Θ Reliability Scorer — Θ = 0.35C̄ + 0.25(1-D̄) + 0.20/(1+E) + 0.20S
- Thread-safe SessionMonitor — RLock-protected, evaluate() never blocks for >10ms
- Pre-compiled AST — all regex patterns compiled once at SessionStart
Install
pip install agentassert-typec-core
Quickstart
from agentassert_typec_core import SessionMonitor, PreAction, DecisionResult
monitor = SessionMonitor.from_yaml("contract.yaml")
event = PreAction(session_id="s1", contract_id="c1", tool="Read", args={})
result = monitor.evaluate(event)
print(result.decision.name) # ALLOW or DENY
Optional: OTel
pip install agentassert-typec-core[otel]
