ZenMoney Sync

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

With no annotations, the description carries the full burden. It only states 'synchronize,' which implies updating the in-memory snapshot, but it doesn't disclose side effects (e.g., network calls, data overwrite), authorization requirements, or whether the tool is read-only or destructive. This is insufficient.

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 sentence, which is concise. However, it is too terse, missing essential information. It is front-loaded but underspecified. A score of 3 reflects adequate conciseness but inadequate structure.

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?

Given no output schema and only one parameter, the description should explain what the tool returns, the effect on the snapshot, and the meaning of 'full'. It fails to provide enough context for the agent to use it correctly. Completeness is low.

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?

The 'full' boolean parameter has no description in the schema or the tool description. Schema coverage is 0%, and the description does not explain what 'full' means (e.g., full vs. incremental sync). The agent cannot infer parameter semantics.

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 specifies a verb ('Synchronize') and a resource ('the in-memory ZenMoney snapshot'), clearly indicating the tool's action. However, it doesn't differentiate from sibling tools like 'zenmoney_cache_status', which might check the sync status. The purpose is clear but lacks context.

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 tool versus alternatives. The description does not specify prerequisites, scenarios, or when not to use it. For a sync operation, it should mention that it may be called before reading data or after modifications.

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