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

No annotations provided. 'Retrieve' implies a read, but the description gives no behavioral context: no auth requirements, error handling, or side effects. It does not contradict anything, but it leaves the full disclosure burden unmet.

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?

Single sentence, front-loaded, zero wasted words. Appropriate for a simple retrieval tool.

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?

An output schema exists, so return values need not be described. However, for a tool with no annotations and no schema descriptions, the description omits task context such as how to obtain the hash or what errors to expect, leaving it minimally 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 0% and the one parameter is only a string. 'By hash' echoes the parameter name (idea_hash) without explaining hash format, source, or constraints. Adds almost no meaning beyond the schema.

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 (Retrieve), resource (idea), scope (single), and lookup key (by hash). Clearly distinguishes itself from list_ideas (multiple) and generate_idea (creation).

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?

Implies usage when an idea hash is known, but does not name alternatives or state when not to use it. No explicit routing to list_ideas or generate_idea.

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