Implementation Reference

  • src/aws_agentcore_mcp_server/server.py:21-26 (handler)
    The handler function for the 'quickstart' MCP tool, registered via @mcp.tool() decorator. It loads and returns the content of quickstart.md from the package data.
    @mcp.tool()
async def quickstart() -> str:
    """Quickstart documentation for AWS AgentCore SDK."""
    return pkg_resources.joinpath("content", "quickstart.md").read_text(
        encoding="utf-8"
    )
  • src/aws_agentcore_mcp_server/server.py:5-5 (helper)
    Helper variable providing access to package resources (content files) used by the quickstart tool and others.
    pkg_resources = resources.files("aws_agentcore_mcp_server")

Tool Definition Quality

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden for behavioral disclosure. It states the tool provides documentation but doesn't specify whether this is read-only, if it requires authentication, how it retrieves or displays the documentation, or what format the documentation takes. For a tool with zero annotation coverage, this leaves significant behavioral questions unanswered.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, efficient sentence that states exactly what the tool does without unnecessary words. It's appropriately sized for a zero-parameter documentation tool and front-loads the essential information. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (0 parameters, 100% schema coverage, output schema exists), the description is reasonably complete. The existence of an output schema means the description doesn't need to explain return values. However, for a documentation tool with no annotations, it could benefit from specifying the documentation format or access method to be fully complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description appropriately doesn't discuss parameters since none exist, and the schema fully documents this absence. No additional parameter information is needed or provided.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool provides 'Quickstart documentation for AWS AgentCore SDK' - a specific resource (documentation) with a clear purpose (getting started). It distinguishes from siblings by focusing on documentation rather than functional components like code interpretation or identity management. However, it doesn't specify the exact format or delivery method of this documentation.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. There's no indication of prerequisites, timing considerations, or comparison to other documentation tools. The agent must infer usage from the tool name and description alone without explicit guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
