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

Adds substantial behavioral detail beyond the annotations: patch replaces only supplied fields, an empty string/list clears a field (matching destructiveHint), it activates context and runs the learning pipeline as a side effect, and it refuses mid-interview. These side effects and destructive semantics are exactly what an agent needs and are not derivable from the structured fields alone.

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?

Front-loads the core action in the first clause, then layers the field list, patching semantics, side effects, and refusal conditions in dense, non-redundant sentences. Every sentence carries decision-relevant information with no filler.

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 destructive, nested-object mutation with no output schema, the description covers the prerequisites (confirmed AI usage), refusal condition (in-progress interview), field-clearing behavior, and side effects (fact extraction via learning pipeline). Nothing needed to call it correctly is conspicuously absent.

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?

With only 33% schema description coverage, the description usefully names the patch fields and, crucially, explains the replace-vs-clear semantics that the schema does not convey. It leaves brandId semantics unaddressed and does not describe confirm beyond what the schema description already states, so it compensates well but not completely.

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?

States a specific verb (Save) and resource (structured creator context from an interview) and enumerates the exact fields involved (origin, goals90, winningContent, struggles, themes, voice). An agent can clearly distinguish this from siblings like update_creator_memory, get_creator_context, and add_creator_fact without opening any schema.

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?

Gives clear context for use (saving structured interview output) plus exclusions: refuses during an in-progress Dalea interview, requires confirmed AI usage, and explicitly notes it does not rewrite conversation history or regenerate memory. It stops short of naming the alternative tool an agent should reach for when those conditions fail, so it is strong but not fully prescriptive.

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