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 actions but doesn't describe side effects (e.g., delete is destructive), permissions required, rate limits, or response formats. For a multi-action tool with potential mutations, this is a significant gap in transparency.

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—two sentences with zero waste. It front-loads the core purpose and enumerates actions efficiently. Every word earns its place, making it easy for an agent to parse quickly.

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 (4 parameters, multiple actions including mutations) and lack of annotations or output schema, the description is incomplete. It doesn't cover behavioral aspects like side effects, authentication, or error handling, which are critical 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?

Schema description coverage is 100%, so the schema already documents all 4 parameters thoroughly. The description adds minimal value by listing the action enums, which are already in the schema. Baseline 3 is appropriate as the schema does the heavy lifting, but the description doesn't provide additional semantic context beyond what's structured.

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 tool's purpose: managing Jira issue attachments with specific actions (list, download, upload, delete). It specifies the resource (Jira issue attachments) and verbs (manage with enumerated actions). However, it doesn't explicitly differentiate from sibling tools like manage_issues or manage_boards, which might also handle attachments indirectly.

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. It lists actions but doesn't explain prerequisites (e.g., authentication needs), when to choose upload vs. other methods, or how it relates to sibling tools like manage_issues. This leaves the agent with minimal context for decision-making.

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