get_project_timeline

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

With no annotations, the description carries the full burden; 'Get' signals a read-only operation and 'status timeline and duration' discloses the shape of the result. It says nothing about ordering, date ranges, how duration is computed, or whether the timeline is truncated, which are the details that matter for interpreting the output.

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?

One short, front-loaded sentence with no filler. It is efficiently written, though the brevity is closer to under-specification than to dense information.

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 one-parameter read tool, this is minimally adequate, but with no output schema the description should explain what a 'timeline' entry contains and how 'duration' is measured. Those omissions leave an agent unsure of what it will actually receive.

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?

There is a single required parameter with 100% schema description coverage, so the schema already documents projectName fully. The phrase 'for a project' merely restates that parameter and adds no format or lookup guidance (e.g., exact name vs. ID).

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 names a specific verb ('Get') and resource ('status timeline and duration for a project'), and it even states what the response contains. However, it does not distinguish itself from the closely related sibling get_project_status, leaving the agent to guess which tool yields which view of project status.

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?

There is no guidance on when to use this tool versus get_project_status or get_project_health, and no mention of prerequisites or exclusions. The only implied context is that a project name is required.

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