Implementation Reference

  • Handler for the 'append_insight' tool. Appends the provided insight to the database's insights list, synthesizes a memo, notifies clients of the update, and returns a success message.
    elif name == "append_insight":
        if not arguments or "insight" not in arguments:
            raise ValueError("Missing insight argument")
    
        db.insights.append(arguments["insight"])
        _ = db._synthesize_memo()
    
                # Notify clients that the memo resource has changed
        await server.request_context.session.send_resource_updated(AnyUrl("memo://insights"))
    
        return [types.TextContent(type="text", text="Insight added to memo")]
  • Registration of the 'append_insight' tool in the list_tools handler, including name, description, and input schema.
    types.Tool(
        name="append_insight",
        description="Add a business insight to the memo",
        inputSchema={
            "type": "object",
            "properties": {
                "insight": {"type": "string", "description": "Business insight discovered from data analysis"},
            },
            "required": ["insight"],
        },
    ),
  • Helper method in LogDatabase class that generates a formatted business intelligence memo from the list of insights. Called after appending a new insight.
    def _synthesize_memo(self) -> str:
        """Synthesizes business insights into a formatted memo"""
        logger.debug(f"Synthesizing memo with {len(self.insights)} insights")
        if not self.insights:
            return "No business insights have been discovered yet."
    
        insights = "\n".join(f"- {insight}" for insight in self.insights)
    
        memo = "📊 Business Intelligence Memo 📊\n\n"
        memo += "Key Insights Discovered:\n\n"
        memo += insights
    
        if len(self.insights) > 1:
            memo += "\nSummary:\n"
            memo += f"Analysis has revealed {len(self.insights)} key business insights that suggest opportunities for strategic optimization and growth."
    
        logger.debug("Generated basic memo format")
        return memo
  • Initialization of the insights list in LogDatabase __init__ method, used to store business insights.
    self.insights: list[str] = []
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Add' implies a write operation, but the description doesn't specify whether this requires authentication, what happens if the memo doesn't exist, if there are rate limits, or the format of the memo. This leaves significant gaps in understanding the tool's behavior.

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 directly states the tool's purpose without any wasted words. It's appropriately sized and front-loaded, making it easy to parse quickly.

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

Completeness2/5

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

Given the complexity of a write operation with no annotations and no output schema, the description is insufficient. It doesn't explain what a 'memo' is in this context, how insights are formatted or stored, or what the tool returns upon success or failure, leaving the agent with incomplete information.

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

Parameters3/5

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

The input schema has 100% description coverage, with the 'insight' parameter clearly documented as 'Business insight discovered from data analysis'. The description doesn't add any extra meaning beyond this, so it meets the baseline for high schema coverage without compensating further.

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 action ('Add') and the target resource ('business insight to the memo'), making the purpose understandable. However, it doesn't distinguish this tool from potential sibling tools like 'write_query' or 'log-query' that might also involve adding content, which prevents a perfect score.

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. With sibling tools like 'write_query' and 'log-query' that could involve similar data operations, there's no indication of context, prerequisites, or exclusions for using 'append_insight'.

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