Tools & Capabilities Breakdown

Agentguard Tools (7)

policy_preflight

Pre-flight check before any tool call. Evaluates 7 policies, computes risk score, detects threats, auto-logs. Returns `allowed`/`denied`/`require_approval`/`flagged`.

tool_risk_score

0-100 risk score for tool + input. Detects secrets (API keys, passwords), prompt injection, high-value amounts. `eth_gas`→5, `payment_execute`→95+.

approval_required

Check if tool needs human approval. Optionally registers a pending approval request with tracking URL.

audit_log_write

Write tool execution to persistent, cryptographically-signed audit log (SQLite WAL). Call after execution to record outcome.

audit_log_query

Query audit trail. Filter by agent, tool, decision, time range. Paginated. Returns signed entries for tamper verification.
