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

The description says remove deletes a note by id, which is a destructive operation, while annotations declare destructiveHint=false; this is a direct contradiction. It otherwise adds useful context (judge reads daily, founder edits in results app, free), but the contradiction dominates.

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 paragraph is front-loaded with what to save, then covers remove and cost in compact sentences. It is dense but not bloated; each clause adds a usable detail.

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 save tool with no output schema, the description covers what to persist, who sees it, and cost, but omits what a successful call returns (e.g., a note id) and whether removal is permanent or reversible. Combined with the destructiveHint contradiction, the behavioral picture is not fully complete.

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 the schema already defines all three parameters. The description still adds nuance: 'theirs where you can' for text, 'when the founder says it no longer holds' for remove, and 'question: true closes it' for the boolean flag.

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 states a specific action (keep/save a note) and enumerates the three kinds of content—rules, product facts, and answers to grow's daily question—so the agent knows what qualifies. It does not explicitly distinguish grow_notes_save from sibling note tools such as notes_save or grow_answer, leaving some ambiguity about which note store to target.

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 provides a criterion for when to save (something the founder said that should hold from now on) and when to use remove (founder says it no longer holds). It does not name alternatives or explain when another sibling like notes_save should be used instead, so the agent must infer routing.

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