v5.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so 'Read-only' and 'Does not write personas' largely restate structured data. 'Returns JSON suggestions' is also covered by the existing output schema. The only added context is the scope ('from live Studio personas'), which is modest given annotations carry the rest.
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?
Four short sentences, front-loaded with the action, then the exclusion, then the alternative. Slight redundancy in repeating read-only behaviour already declared by annotations, but nothing is wasted.
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?
With zero parameters and an output schema already documenting the return shape, the description covers nearly everything needed. The one unresolved question – which personas get analysed and roughly what a suggestion contains – is a minor gap for a no-arg tool.
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?
The tool takes zero parameters, so the schema has nothing to document and the baseline is 4. The description's phrase 'from live Studio personas' at least implies the selection is implicit (it works off existing personas), though it never confirms that.
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?
Specific verb+resource: it proposes edits to existing Studio personas rather than creating them, and names the source ('live Studio personas'). An agent can separate it from generate_persona, though it never states whether it targets one persona or all of them.
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?
'Does not write personas. Use generate_persona to create one' gives an explicit exclusion plus a named alternative. What's missing is any guidance about what the caller needs to have in place (e.g. existing live personas) for the tool to do anything.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
