send_discord_alert

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

No annotations are supplied, so the description carries the full behavioral burden, yet it discloses nothing beyond the payload shape. It does not state whether this is a network write, what happens on webhook failure, whether a default webhook must be preconfigured, or any rate-limit/permission constraints.

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?

A single, front-loaded sentence with no filler; the verb and target channel lead the sentence. It is efficient, though arguably too terse given the tool's network-write nature.

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?

Five optional parameters, no annotations, and no output schema leave meaningful gaps: the description never notes that all parameters are optional, what a minimal call produces, or how a missing webhook_url is resolved. For a network-mutating tool with zero annotation support, this is under-specified.

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 all five parameters (color, title, content, description, webhook_url) are already documented in the schema, including the hex color values and the webhook override. The description adds no parameter-level meaning beyond that, so the baseline of 3 applies.

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 and resource ("Send... to a Discord channel") and the payload type ("rich webhook notification or embed"). The Discord platform makes it distinguishable from send_telegram_message without opening a schema, though the text never explicitly contrasts the two siblings.

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?

No when-to-use guidance, no prerequisites, and no mention of when to prefer this over send_telegram_message or how it relates to get_channel_status. The only implied usage is 'to send Discord alerts,' which restates the name rather than guiding selection.

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