set_versioning

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

Annotations already declare readOnly=false, destructive=true, idempotent=false, and the description adds genuinely new context: a risk tag ([WRITE][risk=medium]), a reversibility claim ('Reversible → prior state'), and the semantics of dry_run as a preview mode. Note the mild tension between 'Reversible' and destructiveHint=true, but reversibility and destructiveness are not mutually exclusive, so this is added context rather than a contradiction.

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 action line followed by a compact Args list. Given 0% schema coverage the per-parameter lines are load-bearing rather than redundant, and there is no 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 4-param write tool with no output schema, the description covers action, safety posture, reversibility, dry_run, and every parameter. It omits the side effects an agent would want on a versioning mutation - what happens to existing object versions when suspended, and any permission prerequisites - which keeps it short of full completeness.

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 0%, so the description carries the full burden and does: it documents all four parameters, including an allowed-value set for status ('Enabled' or 'Suspended') that the schema lacks as an enum, the provenance hint for bucket_name ('from bucket_ls'), the target fallback behavior, and dry_run semantics.

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 pair and resource: 'Enable or suspend bucket versioning.' The set/write verb set clearly separates it from read siblings such as bucket_versioning_get, so an agent can tell the tools apart without opening a schema.

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?

Usage is only implied by the verb and the dry_run parameter. There is no explicit when-to-use, no when-not-to-use, and no routing guidance toward the sibling versioning reader (bucket_versioning_get) or related lifecycle tools; the agent must infer context.

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