get_node_timeline

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

With no annotations provided, the description carries the full burden. It discloses that the timeline is newest-first and compact, which is useful. But it does not describe what a 'change timeline' contains, how the limit parameter behaves, or whether it is read-only (though this is implied). More detail could be added without much cost.

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 sentences, front-loaded with the core purpose, and no redundant phrasing. Every word earns 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?

The description is adequate for a simple read tool but lacks details on return format or content. With no output schema, the agent must infer what a 'timeline' consists of. The reference to get_object_history helps, but more explicit information about the response shape would improve completeness.

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 only 50%, and the description adds no information about parameters. It does not explain the meaning of 'limit' or 'endpoint', and 'since' is only briefly described in the schema. The description should compensate for half the parameters being undocumented, but it does not.

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 it returns a compact newest-first change timeline for a single schema object, and the phrase 'App-facing companion to get_object_history' distinguishes it from the sibling get_object_history tool. This is a specific verb+resource with clear scope.

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 indicates it is the app-facing companion to get_object_history and is sized for the visualizer detail panel, which gives clear context for when to use it. However, it does not explicitly state when not to use it or mention alternatives like get_recent_changes.

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