get_timeline_setting

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

No annotations exist, so the description carries full burden. It only states 'Read', which implies a non-destructive operation, but fails to disclose important behavioral traits such as what happens on missing keys, return format, or error conditions. For a simple read, this is minimal 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 a single sentence with a parenthetical note, containing zero wasted words. The key information is front-loaded, making it instantly scannable.

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 simplicity (one parameter, no output schema), the description is mostly adequate. However, it does not specify the return format (e.g., string, object) or error scenarios, leaving gaps for an agent to infer. A complete description would briefly mention what is returned.

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 0%, so the description must compensate. It adds critical meaning that an empty key returns all settings, going beyond the schema which only specifies type and default. This significantly aids parameter understanding, though it could mention valid key values.

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 action 'Read' and resource 'current-timeline setting', making the purpose obvious. While sibling tools like set_timeline_setting exist, the description does not explicitly differentiate from them, but the verb 'Read' vs 'set' provides implicit distinction.

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 includes a useful usage hint ('empty key = all'), implying that omitting the key returns all settings. However, it does not provide explicit guidance on when to use this tool over alternatives (e.g., get_project_setting) or any exclusions, leaving some ambiguity.

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