What You Can Build

Tool functions that connect your AI assistants to real systems — safely and reliably.

  • Actionable AI Tools

    Define tool functions that assistants can call to perform real-world actions.

    • Call external APIs & internal services
    • Trigger workflows and state changes
    • Write to CRM/ERP/helpdesk systems
    • Run calculations and business rules

  • Structured Inputs & Outputs

    Force predictable tool usage with schemas and validated parameters.

    • JSON schema-like parameters
    • Type-safe inputs
    • Deterministic outputs
    • Consistent tool behavior across models

  • Guardrails & Safety Controls

    Keep agentic behavior safe with permissions, constraints, and explicit policies.

    • Role-based permissions (RBAC)
    • Allowlist endpoints and actions
    • Rate limits and quotas
    • PII-safe design patterns

  • Observability & Operations

    Operate tool-based assistants confidently with logs, retries, and error handling.

    • Tool execution logs
    • Retries & timeout handling
    • Error fallbacks and escalation
    • Performance tracking

Use Cases

Common patterns for agentic assistants in sales, support, and operations.

  • Sales Assistant Actions

    Create leads, qualify requests, check inventory, and schedule follow-ups automatically.

    • Example: Create lead → enrich → assign → book meeting

  • Support Automation

    Fetch order status, open tickets, refund requests, and escalate complex issues to agents.

    • Example: Verify user → fetch order → update ticket → notify agent

  • Operations & Back Office

    Automate repetitive internal tasks with tool calls to finance, logistics, and HR systems.

    • Example: Generate invoice → update ERP → send payment link

Key Benefits

Move from “AI that talks” to “AI that does” — with control and compliance.

  • Faster Resolutions

    Assistants complete tasks instantly by calling tools instead of asking humans to switch systems.

  • Fewer Manual Errors

    Structured parameters and validations reduce mistakes and ensure consistent execution.

  • Scalable Automation

    Handle high-volume operations with repeatable tools and reliable outputs.

  • Full Control & Auditability

    Permissions + logs ensure every action is traceable and compliant with your policies.
