workspace_get_reading_session

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

No annotations are provided, so the description must carry behavioral weight. 'Return' and 'persistent' suggest a read-only retrieval of stored data, but the description does not disclose error behavior, permissions, or what happens when the session_id does not exist. For a simple getter this is acceptable but not complete.

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?

A single, front-loaded sentence with no filler. Every word adds meaning: 'persistent' signals state, 'checkpoints and notes' signals returned content, and 'one' signals a singular lookup.

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?

The tool is a simple single-parameter getter, and the description names the resource and returned content. However, with no output schema and no parameter semantics, an agent still lacks guidance on session_id sourcing and not-found behavior, leaving the description minimally viable rather than fully complete.

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 0%, and the only parameter, session_id, is documented only by its title. The description does not explain what session_id values look like, where to obtain them, or how they relate to the reading session being returned, so it fails to compensate for the sparse schema.

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 uses a specific verb ('Return') and resource ('persistent reading session') and notes that it includes checkpoints and notes. This clearly distinguishes it from create/list/queue tools, though it does not explicitly name a sibling alternative.

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 use when a caller needs a single existing reading session with its checkpoints and notes, but it does not explicitly state when not to use it or name alternatives such as workspace_list_reading_sessions or workspace_get_reading_queue. The usage context is inferred rather than stated.

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