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. 'Delete an expense' implies a destructive mutation, but it doesn't specify whether deletion is permanent, reversible, requires specific permissions, or has side effects (e.g., affecting related records). This is a significant gap for a destructive tool with zero annotation coverage.

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

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

The description is extremely concise with a single sentence 'Delete an expense', which is front-loaded and wastes no words. Every part of the sentence directly contributes to the tool's purpose, making it efficient and well-structured for its brevity.

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

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

Given the tool's complexity (destructive mutation with no annotations and no output schema), the description is incomplete. It lacks critical information such as behavioral traits (e.g., permanence, permissions), usage context, or output expectations. This makes it inadequate for safe and effective use by an AI agent.

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

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

The input schema has 1 parameter with 100% description coverage ('Expense ID'), so the schema fully documents the parameter. The description adds no additional parameter information, but with 0 parameters needing semantic clarification beyond the schema, a baseline of 4 is appropriate as it doesn't detract from the schema's completeness.

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

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

The description 'Delete an expense' states the action (delete) and resource (expense), which is clear but minimal. It distinguishes from sibling tools like 'delete_contact' or 'delete_project' by specifying the expense resource, but lacks specificity about scope or permanence. It's not tautological but remains vague about what 'delete' entails.

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

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

No guidance is provided on when to use this tool versus alternatives. For example, it doesn't mention prerequisites (e.g., needing an expense ID from 'get_expense_by_id'), exclusions, or comparisons to other deletion tools like 'delete_contact'. The description offers no context for usage decisions.

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