solidify_tool

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the outcome (saving a reusable named tool) but does not disclose side effects, overwrite behavior, persistence, what counts as 'successful,' or how the tool relates to prior execution state. For a mutation-like tool, this is a significant 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 compact and front-loaded, stating the core purpose in the first sentence and following with useful parameter format hints. There is no filler or redundant restating of the tool name.

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?

Given 6 parameters, no annotations, and an output schema that covers return values, the description still leaves important gaps: what 'source_query' means, how a successful code execution is identified, and any prerequisites. The agent has enough to attempt a call, but not to confidently ensure correct invocation. An output schema does not excuse missing parameter context.

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 the description must compensate. It adds meaningful format details for 'parameters' ('JSON array of {name, type, description, source?, default?, choices_from?}') and 'tags' ('comma-separated tags'), which the schema does not provide. However, it leaves 'source_query' and the top-level 'description' field unexplained, and code/name are only self-evident from their names. Partial compensation only.

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 uses a specific verb and resource: 'Save a successful code execution as a reusable named tool.' This clearly distinguishes it from sibling tools like execute_code (executes), run_tool (runs a tool), and list_tools (lists tools). An agent can immediately understand what this tool accomplishes.

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?

The phrase 'successful code execution' implies the tool should be used after code has been executed successfully, providing some contextual guidance. However, the description does not explicitly say when to use this tool over alternatives, nor does it mention exclusions or prerequisites. Usage context is implied rather than stated.

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