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

With annotations only saying readOnlyHint=false, openWorldHint=true, destructiveHint=true, the description carries substantial extra context: mcp:write permission required, destination is a human-reviewed Lightbringer Slack channel, only text/category/tool_name are transmitted, no account or client metadata is attached, the channel is hidden from the user, and transcripts/documents/invention details are excluded. This is well beyond what the annotations convey.

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-loads the purpose in the first sentence and each subsequent sentence covers a distinct consent, permission, or privacy fact. It is on the long side, and the closing sentence partly repeats the earlier 'no metadata / no confidential material' point, but nothing is filler given the privacy stakes.

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 no explanation, and the description covers consent flow, required permission, recipient, data-minimization scope, and the visibility caveat. An agent has everything needed to decide whether and how to call it.

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% and all three parameters (category, feedback, tool_name) are documented in the schema itself, so the baseline is 3. The description restates the payload contents ('report text, category and optional tool name') but adds no format or constraint detail 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+resource ('Sends feedback ... about the Lightbringer tools') and enumerates the three content types it covers: broken/surprising behaviour, missing capabilities, friction. It is distinguishable from siblings such as start_innovation_feedback because it is explicitly scoped to tool-level issues rather than innovation feedback.

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?

Gives a clear precondition (user's explicit consent after seeing the report text, category, optional tool name, and being told the recipient) and a clear content trigger (tool bugs, missing capabilities, friction). It does not name an alternative tool or state when NOT to use it, so it falls short of a 5.

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