    Why it matters

    It lets teams embed a proven coding-agent harness in their own applications while choosing the permissions and tools the agent may use.

    Example

    A team evaluating Claude Agent SDK can compare its delivery model, lifecycle, tools, memory, approvals, and evaluation surface with Claude Code before choosing an architecture.

    Common confusion

    Including Claude Agent SDK in this learning center does not mean OverLift uses, endorses, or treats every advertised capability as independently verified.

    How OverLift uses it

    The Agentic AI Glossary catalogs Claude Agent SDK as a source-reviewed ecosystem profile. OverLift may compare its role, lifecycle, and capabilities, but the product receives no authority over evidence, policy, execution, or glossary receipts.

    Official and reviewed sources

    Explore the technical detail Formal definition, lifecycle, use boundaries, capabilities, prerequisites, and comparisons

    Technical definition

    The SDK provides programmable sessions, streaming and single-message modes, tool permissions, hooks, subagents, context management, and access to Claude Code's execution-oriented agent behavior.

    Lifecycle and review boundary

    Current public product or framework; recheck official release notes before major adoption decisions.

    Use it when

    Use it when you want to build a programmable tool-using agent around Claude Code capabilities and need explicit control over allowed tools, sessions, and automation entry points.

    Avoid or reconsider when

    Reconsider it when you only need a direct model API call or when the host application cannot safely sandbox file, shell, browser, or network tools.

    LEARN THE SECURITY BOUNDARY

    Retrieval can inform an agent. Retrieved content cannot grant it authority.

    The glossary demonstrates the same OverLift rule it teaches: exact and semantic retrieval may propose useful evidence, but source eligibility, permissions, capability admission, deterministic fallback, Tier-S verification, receipts, and replay decide what the product may trust.

    PRIVACY What information leaves the chosen boundary?

    Prefer browser-local, same-origin, or offline processing; disclose only the approved evidence a remote service actually needs.

    SECURITY What can this code or agent reach, call, change, or persist?

    Use worker and WebAssembly containment, explicit imports, typed tools, deadlines, allowlists, and fail-closed defaults.

    AUTHORITY What is allowed to become official truth or state?

    Keep identity, permissions, policy, approval, exact execution, verification, receipts, and replay outside probabilistic control.
