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. It hints at a mutation ('uses the same authorization and validation') but does not disclose that the tool modifies an existing handoff, whether the change is destructive or reversible, what concurrency/revision semantics apply, or what a status transition means. The claim that it uses 'the same authorization and validation as website, API and CLI' is unverifiable and adds no actionable behavior.

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?

Two short sentences with no wasted words, but the brevity is achieved by omitting essential information rather than by disciplined editing. Front-loading the tool name in dotted notation is not useful to an agent.

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 required-parameter mutation with 0% schema coverage, no annotations, and no output schema, the description is essentially empty. It omits the resource meaning, the mutation semantics, the concurrency model implied by 'revision', and the status enum purpose.

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% across all five required parameters, so the description must compensate and it does not. It never mentions id, workspaceId, revision, status, or owner, nor explains the optimistic-concurrency role of 'revision' or the allowed status enum values.

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 says 'SAGOT handoffs.update' which only restates the tool name in a dotted form. It never states what a handoff is or what updating one does, nor does it enumerate the updateable fields (status, owner) that the schema requires. Compared to siblings like handoffs_list, an agent cannot distinguish the semantics beyond the obvious CRUD verb.

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?

There is no guidance on when to call this tool versus alternatives, no preconditions beyond the vague authorization note, and no mention of what a handoff lifecycle looks like. The single sentence about matching website/API/CLI validation gives no decision criteria.

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