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

The annotations only declare the generic write profile (readOnly=false, destructive=false, idempotent=false); the description adds substantive scope: what is copied (titles, nesting, relative dates, milestones, dependencies) and what is deliberately not (people, progress, comments). That exclusion list is exactly the kind of context annotations can't convey. It stops short of saying what happens on a duplicate name or that repeated calls produce additional templates, which matters given idempotentHint=false.

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, both load-bearing: the first front-loads the capture scope, the second delivers the exclusion list and the permission requirement. Nothing is redundant with the name or title.

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 3-parameter creation tool with no output schema, the description covers source, destination artifact, data scope, and authorization well. The only gap is the return value (the new template's identifier) and duplicate-name behavior, which an agent would need for follow-up calls.

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 100%, so all three parameters are already documented in the schema, making 3 the baseline. The description only marginally enriches them by implying projectId is the source captured and that dates are stored relatively; it adds no format, ID-resolution, or naming-collision detail beyond the schema.

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?

It gives a specific verb and resource ('save a project's task breakdown ... as a workspace template') and enumerates exactly what is captured, so the agent knows the output artifact precisely. It is also easy to separate from the inverse sibling 'create_project_from_template' and from 'list_templates'.

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?

It supplies a real prerequisite – 'Administrator or ProjectManager' – which tells the agent whether the call will be permitted. It doesn't explicitly direct the agent to 'list_templates' to check for name collisions or to 'create_project_from_template' for the reverse flow, so there are no stated alternatives.

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