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

Annotations only flag readOnlyHint=false, destructiveHint=true and openWorldHint=true; the description supplies the substance behind them: the consent gate, the mcp:write permission requirement, the human-reviewed Slack destination, that the channel is invisible to the signed-in user, and that no account or client metadata is attached. It also sets expectations that delivery is one-way ('does not request professional work or promise a response or resolution') and bounds what is transmitted, which is exactly the behavioral context an agent needs before an irreversible external send.

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 purpose and the when-not-to-use constraint are front-loaded, and nearly every sentence carries a distinct obligation (consent, permission, destination, data minimization, no promised response). It is nonetheless a single dense paragraph with visible overlap: 'Only the report text, category and optional tool name are sent' is restated later as 'Reports contain only the issue or unresolved need the user agreed to share.' Slightly tighter or bulleted structuring would improve scanability.

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 an irreversible external-send tool with three parameters, the definition covers the full decision surface: eligibility, consent and permission preconditions, what payload leaves the system, where it goes, who can see it, and what the agent should not promise. An output schema exists, so the absence of return-value detail is not a gap.

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 description coverage is 100%, so the baseline is 3; the description earns above that by adding content-level meaning beyond the schema, namely how to phrase an unmet-need report (intended outcome, help provided, remaining obstacle, confirmed evidence, keep unknowns explicit) and what must be excluded (transcripts, document text, invention details). It reinforces the feedback/category/tool_name restriction but adds no new syntax or edge-case handling for maxLength or the enum values.

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 opens with a specific verb and resource: 'Sends feedback the user explicitly wants to share about Lightbringer tools or customer needs the available assistance could not resolve,' and then enumerates what counts (broken/surprising behaviour, missing capabilities, friction, unresolved customer problem). That is far more specific than the title. It stops short of a 5 because it never names or contrasts the closest sibling, start_innovation_feedback, leaving the agent to infer which feedback channel applies.

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 explicit inclusion criteria (tool bugs, missing capabilities, friction, unresolved customer need), explicit exclusion criteria ('Do not infer a service-wide gap from missing access, evidence or a limitation of this conversation'; not feature proposals or solution suggestions), and hard prerequisites (user must see the report text, category and optional tool name, be told the recipient, and consent). When-to-use, when-not-to-use and preconditions are all present.

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