tempo_approve_timesheet

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

Goes well beyond the annotations by disclosing the concrete destructive effect ('approving locks the period's worklogs against further edits') and the full two-step confirmation protocol including the confirmToken fallback. With destructiveHint=true already set, this adds the 'what gets destroyed' detail annotations cannot convey.

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?

Three front-loaded sentences that lead with the action and its consequence before the procedural detail. The final sentence is dense with a parenthetical, but every clause carries necessary behavioral information.

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 correctly carries the burden of explaining the phase-1 'confirmation-required' response and confirmToken, which is exactly what an agent needs. Minor gaps remain, such as whether approval is reversible via a sibling like tempo_reopen_timesheet.

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 100%, and the confirmToken and from params carry detailed schema-side explanations, so the baseline is 3. The description reinforces the period scoping but adds no syntax or semantics not already present in the 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?

States a specific verb (Approve) plus resource (a user's submitted timesheet) and scope (the given period), and labels it a 'Reviewer action'. This cleanly separates it from siblings like tempo_submit_timesheet, tempo_reject_timesheet, and tempo_reopen_timesheet.

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?

Identifies the caller role ('Reviewer action') and ties the operation to the approval workflow, giving clear context for when to reach for it. It does not explicitly contrast itself with reject/reopen/recall siblings or state exclusions, so it stops short of a 5.

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