read_task_attachment

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

With no annotations, the description carries the full burden. It discloses that images are returned as MCP content when possible, but does not explain behavior for non-image attachments, error conditions, or authorization requirements. This is partial but not comprehensive.

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?

Two concise, front-loaded sentences: first states the core purpose, second adds a key behavioral detail about image handling. No filler or redundancy.

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?

For a simple read tool with 4 well-documented parameters and no output schema, the description is mostly complete. However, it could mention return format for non-images or error scenarios, but the overall simplicity keeps the score high.

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 coverage is 100%, so all parameters have descriptions in the schema. The tool description does not add additional meaning beyond the schema; it only mentions the attachment ID/name references. Baseline 3 is appropriate.

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 reads a task attachment, specifically one reported by get_task_by_id. It adds that images are returned as MCP content when possible. However, it could be more specific about what 'read' entails (e.g., download or view) and does not explicitly differentiate from sibling tools, though no sibling appears to do the same thing.

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 implies that the attachment should be obtained from get_task_by_id, but does not explicitly state 'use after get_task_by_id' or provide alternatives. There is no guidance on when not to use the tool or prerequisites.

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