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

Annotations already declare readOnlyHint=false (write operation) and idempotentHint=false, but the description doesn't add behavioral context beyond the redundant character limit. It fails to disclose what happens on success, potential duplicate creation from repeated submissions, or any side effects, so the agent has little insight into runtime behavior.

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 extremely concise with two short sentences, front-loading the purpose and then adding a constraint. There is no fluff or redundancy beyond the character limit note, which, while redundant with schema, doesn't detract from overall conciseness.

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 simple create tool with no output schema, the description is under-specified. It omits parameter meanings, return value, confirmation behavior, and implications of non-idempotency. The agent can't fully understand what to expect after calling this tool, making it incomplete for reliable use.

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 0% schema description coverage, the description carries the full burden of explaining parameters, but it only repeats the maxLength constraint already in the schema. It doesn't clarify the meaning of redFlag, greenFlag, agentName, or agentKey, providing no additional value over 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?

The description clearly states the tool creates one paired opinion (red/green flag pair), matching the title and using a specific verb + resource. This distinguishes it from the sibling tools (get_board_stats, list_entries, rank_entry) which are all read/rank operations, so there's no ambiguity about its purpose.

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 description implies usage for creating a new paired opinion via the verb 'Create', but provides no explicit when-to-use guidance, exclusions, or comparison with alternatives. Since siblings are non-write operations, the context is clear but not explicitly stated.

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