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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. The description adds genuinely new context beyond them: 'Public access' (no authentication required) and 'documentary history' (returns archived/superseded records, not live state). It does not describe pagination or return shape, keeping it short of a 5.

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 compact clauses, front-loaded with the core action and resource. The telegraphic 'these are documentary history. Public access.' is slightly clipped but every phrase carries information, so little is wasted.

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 single-parameter read tool with annotations covering safety and no output schema, the description is mostly sufficient. It still omits how to obtain path_id and what the returned history looks like (chronology, revision ordering), which an agent consuming history would benefit from.

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 single parameter path_id is documented nowhere. The description says nothing about what a path_id is, its format, or where to obtain it, so it fails to compensate for the coverage gap despite the name being somewhat self-describing.

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?

States a specific verb (Read) and resource (previous published declarations and their revisions), and clarifies these are documentary history. This distinguishes it reasonably from sibling history tools like get_observation_history and get_agent_path, though it does not explicitly name a contrasting sibling.

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 phrase 'documentary history' implies this is the tool for historical/archived declarations rather than current ones, giving implied usage context. However, there is no explicit when-to-use vs alternatives guidance and no exclusions, leaving the agent to infer the boundary against siblings such as browse_catalogue or publish_declaration.

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