markRecurringTransactionDone

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

Annotations already indicate this is a mutation (readOnlyHint=false). The description adds that it marks for the current period, which is useful. However, no details are given about side effects, permissions, or reversibility, which are important for a mutation tool.

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?

The description is a single concise sentence that immediately conveys the core action and scope. No unnecessary words.

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 simple mutation with one parameter and no output schema, the description provides the basic information. However, given the existence of sibling tools with overlapping functionality, more context on the effect and when to use this specific tool would improve 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 100%, so baseline is 3. However, the parameter description ('ID of the recurring transaction to mark as done, skip or delete') is misleading because the tool only marks as done, not skip or delete. This confusion reduces the value added.

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 clearly states the action ('mark as done') and the scope ('for the current period'). However, the parameter description confusingly includes 'skip or delete', which blurs the purpose and does not differentiate it from sibling tools like skipRecurringTransaction and deleteRecurringTransaction.

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 explicit guidance on when to use this tool versus its siblings (skipRecurringTransaction, deleteRecurringTransaction). The description only implies usage for the current period, but does not explain the difference or provide decision criteria.

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