AWS AgentCore

Purpose

Build and operate Amazon Bedrock AgentCore agents without stuffing runtime, harness, Memory, Gateway, Identity, Observability, Browser, Code Interpreter, Evaluations, Registry, Payments, policy, and environment/skills details into every prompt.

When to use

Use this skill when the user asks to:

• create or adapt an AgentCore project,
• configure local development, invocation, packaging, deployment, runtime settings, harness settings, or environment/skills paths,
• integrate AgentCore Memory, Gateway, MCP tools, Identity, Observability, Browser, Code Interpreter, Evaluations, Registry, or Payments,
• review AgentCore security, least privilege, policy, tool exposure, credential handling, migration, or production readiness.

Lean operating rules

• First decide whether the user has an existing agent or needs a new project. Do not scaffold over an existing codebase.
• For new projects, prefer the npm AgentCore CLI package @aws/agentcore because current AWS documentation recommends it.
• Treat the Python starter toolkit as legacy/migration-oriented unless the user is explicitly working inside an existing Python-based toolkit workflow.
• Separate code-based agents from config-based harnesses. Do not mix their guidance casually; current AWS docs describe the harness path as preview.
• Prefer current AWS documentation tools for AgentCore service behavior. Use the component facts and sampled live evidence in references/official-sources.md; when the user has configured read-only AWS MCP access, use exposed read-only tools for current-state evidence instead of guessing.
• Treat CLI syntax as version-sensitive; verify exact commands with installed tooling before production use.
• Treat Gateway policy, identity propagation, skill-path and filesystem loading, observability prerequisites, evaluation loops, registry governance, and payment spending controls as first-class concerns, not afterthoughts.
• Never ask users to paste AWS credentials, client secrets, access tokens, account IDs, customer data, or private keys into chat.
• Load only the reference needed for the component in scope.

References

Load these only when needed:

• Workflow and output contract — use for end-to-end AgentCore project, local test, deployment, and output formatting.
• Safety checklist — use before deployment, tool exposure, credential integration, Memory/Gateway changes, or production recommendations.
• Official sources — use when grounding current AgentCore service behavior and docs URLs.
• Getting started — use for project/runtime/harness/local workflow details, direct code deployment, filesystem mounts, and CLI/Inspector caveats, then verify commands against current toolkit version.
• Memory integration — use only for AgentCore Memory resource and agent wiring work.
• Gateway integration — use only for Gateway, MCP tools, and tool target integration.

Response minimum

Return, at minimum:

• the AgentCore component in scope,
• evidence level and docs/tooling used,
• safest next action,
• command or code path to verify,
• security and rollback caveats.
