Delete Timeslip

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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=false, so safety basics are covered by structured data. The description adds nothing beyond that: it does not say the deletion is irreversible, whether linked time entries/tasks/billing are affected, or what confirmation or permission requirements exist. For a destructive mutation, this is a meaningful gap.

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?

It is a single short, front-loaded sentence with no wasted words. However, its brevity comes from under-specification rather than disciplined editing, so conciseness does not translate into usefulness here.

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 destructive, no-output-schema tool, the description should at minimum state irreversibility and any side effects or preconditions. Instead it only repeats the operation name, leaving the agent without enough context to call it safely.

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% for the single timeslip_id parameter, so the schema itself does the documentation work and the baseline is 3. The description offers no additional meaning, such as where to obtain the ID (e.g., from list_timeslips) or format constraints beyond the schema pattern.

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 'Delete a timeslip from FreeAgent' is essentially a restatement of the tool name (freeagent_delete_timeslip) and title (Delete Timeslip), adding only the product name as new information. The verb+resource is technically specific, but nothing distinguishes it from the sibling CRUD tools (freeagent_update_timeslip, freeagent_get_timeslip, freeagent_delete_task) beyond what the name already conveys.

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 when-to-use guidance: nothing says when deletion is appropriate versus updating the timeslip, nor whether prerequisites (e.g., unbilled, unlocked, or draft state) apply. The agent must infer all of this from the name alone.

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