freeagent_mark_estimate_as_sent

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

Annotations already declare readOnlyHint=false and destructiveHint=false, so the safety profile is partly covered. However, the description adds nothing beyond that: it does not say whether this triggers an actual email to the client, whether it is idempotent, what state the estimate transitions from and to, or what happens on an already-sent estimate. For a state-changing action, that 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?

One short sentence, front-loaded and free of padding. It is concise but only because it says almost nothing; no structural issues exist.

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 state-transition action on a business document, the description omits the most consequential facts: whether marking as sent actually emails the client, whether it is reversible, and what precondition the estimate must meet. With no output schema and minimal annotations, the description should carry more of this burden.

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% with a single required estimate_id documented in the schema, so the baseline is 3. The description contributes no additional meaning about the identifier format or where to obtain it, which is acceptable given the schema already covers it.

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 specific verb and resource (mark an estimate as sent), which is clearer than the bare name in one respect: it reveals the target entity type is 'estimate'. But it is essentially a restatement of the tool name and gives no differentiation from close siblings such as freeagent_mark_estimate_as_approved or freeagent_update_estimate, which an agent would have to disambiguate by opening schemas.

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?

No guidance on when to use this versus update_estimate or mark_estimate_as_approved, and no prerequisites stated (e.g. whether the estimate must be in draft status first). The agent must infer the workflow entirely.

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