library8.8.3jsnpmunverified

AgentSkeptic re-checks downstream stores (SQL, HTTP, vectors, documents, S3) against agent tool activity traces, producing a deterministic Outcome Certificate v3 (schemaVersion:3). Version 8.8.3, Node 22.x/24.x, TypeScript types included. Key differentiator: verifies actual stored state rather than trusting execution traces, catching mismatches that trace-only tools miss. Supports optional coverage budgets for compliance policies. Local 'check' mode runs without license or API key; stateful 'enforce' mode is a commercial opt-in.

agentskeptic check
✓ npx agentskeptic check --workflow-id <id> --project <path> --db <path>
✗ npx agentskeptic --check ...
CLI tool, not a library import. Use npx to run directly.

Runs a single truth check comparing tool activity to downstream SQL state, outputting Outcome Certificate v3 JSON to stdout and verdict lines to stderr.

npx agentskeptic check --workflow-id wf_example --project ./path/to/your-app --db ./path/to/readable.sqlite

affects: >=3.0.0
Errors
