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

No annotations are provided, so the description must carry behavioral disclosure. It indicates a create mutation scoped to 'your account' but omits permissions/auth requirements, idempotency, uniqueness behavior for duplicate names, side effects, and what is returned.

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 definition is a single front-loaded sentence with no redundancy or filler. It is concise and easy to parse, even though it is sparse overall.

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 mutation tool with no annotations and no output schema, the description is too thin. It does not cover required behavior, return expectations, or constraints for the lone undocumented parameter, leaving material gaps an agent would need before calling 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?

There is one parameter, 'name', with 0% schema description coverage, and the description adds no meaning about its format, constraints, uniqueness, or relation to the account scope. It mentions 'standing-instruction ledger' but does not explain the parameter itself.

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 a standing-instruction ledger. That is clearly distinct from compile/diff/execute/verify/version siblings, though it does not explicitly name sibling alternatives or differentiate further.

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?

It gives no guidance on when to use this versus the ledger_* siblings, no prerequisites, and no conditions for creating a new ledger versus acting on an existing one. Usage is only implied by the verb 'Create'.

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