timeline_get_setting

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

The description repeats the readOnlyHint annotation by saying 'Read' but adds no additional behavioral context, such as behavior for missing keys, return format, or side effects. Since annotations already declare safety, the description offers no extra value beyond the structured data.

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, front-loaded sentence with no unnecessary words. It communicates the core purpose efficiently without sacrificing clarity.

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 simple (one parameter, read-only, output schema present), and the description is sufficient given that the input schema details valid keys and the output schema likely describes return values. The description lacks nothing critical for a basic getter, though it could mention current timeline context.

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 for the only parameter 'key' is 100% with concrete examples provided in the schema description. The phrase 'by key' merely restates the parameter name and adds no additional meaning beyond what the schema already documents, aligning with the baseline of 3.

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 ('Read') and clearly identifies the resource ('timeline-specific setting') with the key parameter. It differentiates from sibling tools like timeline_set_setting by indicating a read operation, and from project_get_setting by specifying 'timeline-specific'.

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 gives no explicit guidance on when to use this tool versus alternatives such as timeline_set_setting or project_get_setting. Usage is only implied by the verb 'Read' and the noun 'setting', with no mention of preconditions or exclusions.

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