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

Annotations already declare destructiveHint=true and idempotentHint=true, and the description usefully extends them with side effects (task archival can fire configured webhooks and workspace notifications) and the fact that permissions are enforced at workspace, project, and account level. It still does not say whether archived data is recoverable or what happens to the item's visibility, which is the missing piece for a destructive operation.

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?

Four sentences, all front-loaded with the action first and prerequisites after; nothing is filler. There is mild redundancy in mentioning 'current version' twice (once as the mechanism, once as the source), which keeps it just below the top band.

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, the description still covers the safety-relevant surface: permissions, side effects, and the idempotency/retry pattern. The only real gap is the semantics of un-archiving and what the caller gets back, which is minor given annotations that already flag the operation as destructive and idempotent.

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 25% (only `id` is documented), so the description must compensate, and it does explain `version` provenance and the requestId retry contract well. However it never explains the `archived` boolean, which is the parameter that determines whether the call archives or un-archives — a material omission on a required parameter.

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 precise verb (archive) and enumerates the resource types it applies to (project, task, resource), so an agent can distinguish it from siblings like item_update or association_delete. It does not name or contrast any sibling explicitly, and it never mentions that the `archived` boolean also permits un-archiving, so it is clear but not fully differentiating.

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 actionable context: version must come from get_tasks, get_items, or get_workspace, and requestId must be unique and reused on retry of the exact action. There is no explicit when-not-to-use guidance or named alternative for restoring an item, so it stops short of the top band.

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