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

Annotations only cover safety hints (non-readOnly, non-idempotent), so the description carries the behavioral burden and does so well: it is free, a human is alerted and replies, the result may carry a `self_help` fix for known error codes, and the agent should tell the user in one line. This is rich context beyond structured fields.

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?

Purpose and the loop-retry exclusion are front-loaded, and every sentence carries actionable content. It is dense and somewhat long, but no sentence is filler.

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 write tool with no output schema and no annotations covering behavior, the description supplies the missing return-signal (`self_help`), the reply channel, and follow-up semantics. It could say more about what a successful submission returns (e.g. ticket id), but it is close to complete.

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 is 3; the description adds operational meaning by specifying that the report should include the failing tool, its error code/status, and what was tried, and that ticket_id is for adding detail to an earlier report rather than opening a new one. That is a modest lift above the already-complete 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 states a specific verb+resource ('Tell the ProductClank team a tool failed...') and enumerates the exact triggering conditions (failure, nonsense result, being stuck). It is clearly distinguishable from siblings, explicitly routing the agent to get_support_status for replies.

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 when-to-use (instead of retrying a failing call in a loop) and when-not-to-use (expected guards like insufficient credits, confirmation prompts, spend caps — relay those to the user). The follow-up path via ticket_id vs. opening a new report is also specified.

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