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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful scope information — that it spans all work items in the project and captures their latest revisions — but says nothing about whether work items are modified, whether repeated calls create duplicates, or what is returned.

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?

A single sentence with the action and scope front-loaded and no wasted words. Nothing is redundant with the title or schema.

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 two-parameter creation tool with annotations and full schema coverage, the description is adequate but thin. With no output schema, an agent is left not knowing what identifying information (e.g., baseline ID) comes back from the call.

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 100%, so both parameters are documented in the schema; the baseline is 3. The description implies project scoping for project_id but adds no format, constraint, or naming-uniqueness detail beyond what the schema provides.

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 states a specific verb+resource: 'Capture the latest revisions ... as a baseline' for a project. It clearly reads as a creation operation, distinct from the get_/list_ baseline siblings, though it does not name those siblings explicitly.

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?

Usage is only implied: an agent can infer this is for snapshotting a project's current state. There is no explicit guidance on when to create a baseline versus retrieving one with get_project_baseline/list_project_baselines, and no prerequisites or side-effect conditions are given.

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