get_ready_to_assign

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

No annotations are provided, so the description carries the full burden. It does useful semantic work by defining what 'Ready to Assign' actually measures, which implies a safe read, but it says nothing about permissions, behavior when no budget exists, whether the figure is a plain number or a formatted/currency object, or error conditions.

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 sentence, front-loaded with the verb and resource, with a clarifying gloss appended after the dash. No filler and nothing extraneous.

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 single-parameter read with no output schema, the description gets close to sufficient by explaining what value is returned rather than just restating the name. A minor gap remains: it doesn't indicate the return type or whether other budget metrics are needed alongside it.

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% and the single budget_id parameter is fully documented in the schema, including the 'last-used' default, so the description adds nothing beyond it. Baseline 3 applies when the schema does all 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?

States a specific verb (Gets) and a specific resource (the current 'Ready to Assign' amount for a budget), and defines the domain term in-line as 'the money not yet assigned to any category this month.' No sibling is named, but the resource is distinct enough from get_month_summary or get_category_targets that disambiguation is easy.

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?

Usage is implied by the read-only getter framing: call it when you need the unassigned balance. There is no statement of when-not to use it, no mention of alternatives (e.g., get_month_summary for a broader picture), and no prerequisites. Adequate but leaves routing to inference.

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