wafeq_manual_journals_create

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

The description goes beyond the annotations by explaining the concrete consequence of non-idempotency: 'calling twice creates two records.' It also tells the agent how to mitigate this with an idempotency_key, which is actionable behavioral context that the annotations alone do not provide.

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 short, but it repeats the same core idea three times: '🟡 WRITE · creates data', 'Create manual journal', and 'Endpoint for creating a new manual journal.' The idempotency guidance is valuable, but the redundancy means not every sentence earns its place.

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?

The description, combined with a highly detailed input schema, gives an agent enough to select and invoke the tool correctly. It lacks an explicit statement about what the response contains, but no output schema is provided and the core invocation details are covered elsewhere. The non-idempotency warning is important context that is present.

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 input schema covers 100% of parameters with detailed descriptions, including the nested body and idempotency_key semantics. The description adds only a brief reminder about idempotency safety, which is useful but largely redundant with the schema's own explanation. Baseline of 3 is appropriate because the schema does the heavy lifting.

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: 'Create manual journal' with the exact endpoint 'POST /manual-journals/'. The '🟡 WRITE · creates data' prefix makes the operation type unmistakable, and the presence of sibling create/update/destroy tools for the same resource makes this unambiguous.

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?

The description clearly identifies the tool as the creation endpoint for manual journals, so the intended use is clear. It does not explicitly list alternatives such as update or partial_update, but the create-vs-modify distinction is strongly implied by the resource and action. It also adds practical guidance about idempotency for retries.

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