Implementation Reference

  • src/index.ts:220-233 (registration)
    MCP tool registration defining the name, description, and input schema for remove_from_whitelist
    {
      name: 'remove_from_whitelist',
      description: 'Remove a command from the whitelist',
      inputSchema: {
        type: 'object',
        properties: {
          command: {
            type: 'string',
            description: 'The command to remove from whitelist',
          },
        },
        required: ['command'],
      },
    },
  • Primary MCP handler for the tool: validates arguments with Zod and delegates to CommandService.removeFromWhitelist, returning success message
    private async handleRemoveFromWhitelist(args: any) {
      const schema = z.object({
        command: z.string(),
      });
    
      const { command } = schema.parse(args);
    
      this.commandService.removeFromWhitelist(command);
    
      return {
        content: [
          {
            type: 'text',
            text: `Command '${command}' removed from whitelist`,
          },
        ],
      };
    }
  • Supporting method in CommandService that performs the actual removal by deleting the entry from the internal whitelist Map
    public removeFromWhitelist(command: string): void {
      this.whitelist.delete(command);
    }
Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool removes a command from a whitelist, implying a mutation operation, but doesn't describe side effects (e.g., whether this affects pending commands or security levels), permissions required, or error conditions. This leaves significant gaps in understanding how the tool behaves beyond its basic function.

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, clear sentence with zero wasted words. It's front-loaded with the core action and resource, making it highly efficient and easy to parse.

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 tool's mutation nature (removing from a whitelist), lack of annotations, and no output schema, the description is incomplete. It doesn't cover behavioral aspects like what happens after removal, error handling, or integration with sibling tools (e.g., 'get_whitelist'), leaving the agent with insufficient context for safe and effective use.

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 single parameter 'command' documented as 'The command to remove from whitelist'. The description doesn't add any meaning beyond this, such as format examples or constraints, but the schema provides adequate baseline information, justifying a score of 3.

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 ('remove') and target resource ('a command from the whitelist'), making the purpose immediately understandable. It doesn't explicitly differentiate from siblings like 'deny_command' or 'update_security_level', which might have overlapping security functions, but the verb+resource combination is specific enough for basic understanding.

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 like 'deny_command' or 'update_security_level', nor does it mention prerequisites (e.g., whether the command must already be in the whitelist). It simply states what the tool does without contextual usage information.

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