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

Annotations indicate destructiveHint=true, which aligns with the 'Delete' action, and openWorldHint=true, suggesting variable IDs might not be pre-known. The description adds minimal context beyond this, as it does not specify irreversible effects, permissions required, or rate limits. However, it does not contradict annotations, so it meets a baseline level of transparency with annotations covering key safety aspects.

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 a single, direct sentence that efficiently conveys the core action without unnecessary words. It is front-loaded with the key information ('Delete an environment variable'), making it easy for an AI agent to parse quickly. Every part of the sentence serves a purpose, earning its place.

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 (a destructive operation with one parameter) and the presence of annotations (destructiveHint, openWorldHint) but no output schema, the description is minimally adequate. It states what the tool does but lacks details on outcomes (e.g., confirmation messages, error handling) or integration with sibling tools, leaving gaps in completeness for safe and effective use.

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 100% description coverage, with the parameter 'variableId' clearly documented as 'Variable ID (format: esv-*)'. The description does not add any semantic details beyond this, such as how to obtain the ID or validation rules. Given the high schema coverage, a baseline score of 3 is appropriate, as the schema carries the primary burden of parameter documentation.

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 clearly states the verb ('Delete') and resource ('environment variable (ESV) from PingOne AIC'), making the purpose unambiguous. However, it does not differentiate from sibling tools like 'deleteManagedObject' or 'deleteTheme', which also delete resources in the same system, leaving room for potential confusion about when to use this specific deletion tool.

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?

The description provides no guidance on when to use this tool versus alternatives. For example, it does not mention prerequisites (e.g., needing the variable ID from 'getVariable' or 'queryESVs'), exclusions, or comparisons to similar tools like 'setVariable' for updates. This lack of context could lead to misuse by an AI agent.

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