evolve

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

With no annotations provided, the description carries the full burden of disclosing side effects. 'Update agent personality and triggering evolution' names the effect at a high level but never states whether the change is permanent, whether it overwrites existing personality, or what 'evolution' entails. For a mutation-style tool, this is a significant transparency gap.

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 sentence, which is appropriately brief, but the 'Universal Primitive:' prefix carries no information and 'and triggering evolution' is grammatically awkward and vague. The word budget could be far better spent clarifying the instruction parameter or the meaning of evolution; this reads as under-specified rather than efficiently concise.

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?

Although an output schema exists, the tool mutates agent state and the description fails to clarify the meaning of 'evolution', the expected content of the required instruction parameter, or how this relates to sibling tools like forget. Even for a small two-parameter tool, an agent cannot reliably decide the correct input or predict the outcome.

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 0%, so neither user_id nor instruction has any schema-level explanation. The description does not mention either parameter — especially the required 'instruction' — leaving the agent to guess what content, format, or length an instruction should take. It adds essentially no meaning beyond the parameter names themselves.

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 verb and resource ('update agent personality'), giving a baseline sense of the operation. However, the 'Universal Primitive' prefix is vague framing and 'triggering evolution' is undefined jargon — an agent cannot tell what an evolution is, how it manifests, or how this differs from sibling tools like forget or project. The core action is discernible but the overall purpose is muddled.

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?

No sentence or clause addresses when to call evolve versus its siblings (think, dream, forget, project). There are no conditions, exclusions, or alternative routing. An agent must guess whether evolve is for permanent trait changes, one-off mental operations, or something else entirely.

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