activate_budget

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

With no annotations, the description carries the full burden for behavioral disclosure. It does mention the effect (can receive real transactions) and implies a state change (activating), but it does not disclose side effects, reversibility, permissions, or behavior on already active budgets. Some context is added, but significant gaps remain.

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 front-loads the key information. However, the parenthetical '(action_activate)' adds unnecessary noise and could confuse agents, so it loses a point for 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?

For a simple tool with one parameter and no output schema, the description gives the core purpose and effect, but it lacks parameter semantics and explicit workflow guidance relative to siblings like 'approve_budget' and 'budget_vs_actual'. It is minimally viable but leaves gaps.

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 has one parameter 'budget_id' with no description (0% schema coverage), and the description does not explain what this ID refers to, how to obtain it, or any constraints. Although the parameter name is somewhat self-explanatory, the description adds no semantic value beyond the schema.

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 tool's action (activate) and its resource (an approved budget), and it specifies the purpose (so it can receive real transactions). This distinguishes it from sibling tools like 'approve_budget' and 'submit_budget' by indicating the budget must already be approved and the activation is the final step before real transactions.

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 provides clear context by requiring the budget to be 'approved', implying this tool is used after 'approve_budget' and before transactions occur. However, it does not explicitly exclude alternatives or state what happens if the budget is not approved, so it falls short of full usage guidance.

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