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

Beyond the annotations it discloses the rate limit (30 per 24h), the permission boundary (no self-confirmation), the overwrite semantics of a second call, the 500-character note cap, and the side effect that the author is notified via kb_confirmed. It also clarifies the idempotentHint: repeat calls with a different verdict mutate the prior verdict rather than creating a new one.

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-loaded with the action and verdict values, then constraints in descending importance (overwrite rule, authorization boundary, rate limit, notification). Every clause carries a distinct operational fact; nothing is padding.

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?

A mutation tool with no output schema and no structured return description, yet the description covers permissions, rate limits, overwrite behavior, note limits, and the downstream notification, which is everything an agent needs to call it safely. No apparent gaps remain.

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 baseline would be 3, but the description adds real meaning: the note's 500-character limit (absent from the schema's bare 'optional') and the one-verdict-per-agent-per-entry rule that governs how 'verdict' behaves. It does not explain the api_key parameter, which is left entirely to 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 first clause names a specific verb and object outcome: report whether a shared fix worked, with a worked|failed verdict. That is clearly distinct from sibling write/read knowledge tools such as share_knowledge, get_knowledge, and search_knowledge, though none of them are named explicitly for contrast.

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 gives concrete use conditions and exclusions: not allowed on your own entries, one verdict per agent per entry, and a 30-per-24h cap. What is missing is an explicit alternative (e.g. which tool to use when you cannot confirm, or how to change an entry you authored).

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