Implementation Reference

  • The handler function that executes the tool logic for 'assess_environmental_fate'. Currently a placeholder implementation returning a not-implemented message.
    private async handleAssessEnvironmentalFate(args: any) {
      return { content: [{ type: 'text', text: JSON.stringify({ message: 'Environmental fate assessment not yet implemented', args }, null, 2) }] };
    }
  • src/index.ts:796-797 (registration)
    Dispatch case in the main request handler that routes execution to the specific tool handler.
    case 'assess_environmental_fate':
      return await this.handleAssessEnvironmentalFate(args);
  • Tool registration object containing the name, description, and input schema definition.
    {
      name: 'assess_environmental_fate',
      description: 'Assess environmental fate including biodegradation and bioaccumulation',
      inputSchema: {
        type: 'object',
        properties: {
          cid: { type: ['number', 'string'], description: 'PubChem Compound ID (CID)' },
        },
        required: ['cid'],
      },
    },
  • src/index.ts:661-671 (registration)
    Registration of the tool in the tools list provided to the MCP server.
    {
      name: 'assess_environmental_fate',
      description: 'Assess environmental fate including biodegradation and bioaccumulation',
      inputSchema: {
        type: 'object',
        properties: {
          cid: { type: ['number', 'string'], description: 'PubChem Compound ID (CID)' },
        },
        required: ['cid'],
      },
    },
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. It mentions assessing environmental fate but does not specify whether this is a read-only operation, requires specific permissions, involves computational predictions, or details output format. 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.

Conciseness4/5

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

The description is a single, efficient sentence that clearly states the tool's function. It is front-loaded with the main purpose and includes specific aspects like biodegradation and bioaccumulation, with no wasted words, making it appropriately concise.

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 environmental fate assessment, lack of annotations, and no output schema, the description is incomplete. It does not address behavioral traits, output details, or how it differs from sibling tools, leaving the agent with insufficient context to use the tool effectively.

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% coverage, fully documenting the 'cid' parameter as a PubChem Compound ID. The description adds no additional meaning beyond this, such as explaining what types of compounds are supported or how the CID is used. With high schema coverage, the baseline score of 3 is appropriate.

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

Purpose3/5

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

The description states the tool assesses environmental fate, specifying biodegradation and bioaccumulation, which clarifies the verb and resource. However, it does not differentiate from siblings like 'get_toxicity_info' or 'predict_admet_properties', which may overlap in environmental aspects, leaving the purpose somewhat vague in context.

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 siblings such as 'get_toxicity_info' and 'predict_admet_properties' that might cover related environmental or toxicity data, there is no indication of specific use cases, prerequisites, or exclusions, leading to potential confusion.

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