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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds value by describing the return payload in detail (counts, remaining credits, per-production suggested tools), which matters because no output schema exists; it doesn't state whether counts are scoped to active vs. all productions or whether results are cached/live.

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?

A single sentence with no waste, front-loaded on the most useful information (identity and credits). It is a grammatical fragment rather than a complete sentence, which slightly reduces polish.

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?

With no output schema, the description steps up by naming the main return fields and noting that each pending production comes with a suggested tool, which is enough for an agent to decide whether to call it first. Missing only scope details such as whether counts include archived/cancelled productions.

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 tool takes zero parameters, so parameter semantics carry no burden and the baseline of 4 applies. The description correctly implies no inputs are needed to get an account-wide summary.

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 enumerates the specific resource contents (signed-in user, credits, storage, production counts, productions needing decisions), which makes the tool's purpose clear even though it is phrased as a noun list rather than a verb+resource. It overlaps with siblings get_credits and list_productions but doesn't explain how it differs from them.

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 only implied: mentioning productions that 'currently need a decision (with the suggested tool for each)' hints the tool is a starting point for triage. There is no explicit when-to-use, when-not-to-use, or pointer to siblings like get_credits or list_productions that cover a subset of the same data.

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