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

Annotations only declare readOnlyHint=false, openWorldHint=true, destructiveHint=false; the description goes well beyond that. It discloses idempotency ('a repeat returns already_filed'), dry-run semantics, the visibility risk of publishing to a public repository, and partial-failure semantics ('filed_unrecorded and outcome_unknown mean the ticket may already exist in the tracker'). Rate limiting and permission-style failures are also surfaced via error codes, though the codes themselves are mostly unexplained.

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 core action and its scope are front-loaded in the first sentence, followed by mapping/idempotency semantics. The trailing 17-item error-code list is dense and largely unglossed, consuming roughly half the text, but it is informationally useful for error handling rather than 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?

With no output schema and openWorldHint=true, the description carries return-value burden and does so: it explains dry_run returns exact tickets, repeats return already_filed, and lists failure codes including ambiguous-outcome cases. Missing pieces are the public_repository reference that has no matching parameter and no explanation of most error codes' remedies.

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 only 33%, so the description must compensate, and it largely does: it documents the 1-50 bound on threat_entry_ids, the dry_run preview behavior, and the destination-as-route-override purpose. The schema describes destination as '{provider, channel_ref, destination}' but the description introduces 'public_repository=true', which appears nowhere in the schema, creating a small ambiguity.

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 and resource with scope: 'Send 1-50 threat report entries to the tracker their route points at (or `destination`)'. It also conveys the one-ticket-per-threat model, telling the agent how entries map to tickets. It never names or contrasts the closest siblings (sync_threat_tickets, get_threat_tickets, list_ticket_destinations), so the agent must infer differentiation.

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 useful invocation context: dry_run for previewing exact tickets, and public_repository for previewing against a public repo. But there is no explicit when-to-use-this-vs-alternative guidance against sync_threat_tickets or get_threat_tickets, and no stated prerequisites such as required role or permissions. Usage is implied rather than routed.

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