StockCake Account

get_account
Read-onlyIdempotent

The signed-in user's plan, credit balance (free / subscription / purchased), next resets and download quality. Requires a free StockCake account (the host will prompt to sign in).

Input Schema

NameRequiredDescriptionDefault
contextYesIn one sentence, what is the user trying to make or find?
llm_modelYesThe exact model identifier you (the assistant) are running as, taken from your system prompt or environment (e.g. "claude-opus-4-8", "gpt-5.2"). Used for analytics only. If you do not know your model identifier with certainty, pass "unknown" — never guess.
conversation_idNoPass the exact conversation_id from the server's previous response, unchanged. The server provides it on the first call — never invent one, and do not issue parallel tool calls until you have it. Keep passing the same conversation_id for the rest of the conversation, including after later user messages or on a different task; do not reset it when the user starts a new request.

  3. First observed

TDQS

A4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint, so safety is covered. The description adds useful behavioral context beyond annotations: authentication is required via a free StockCake account and the host will prompt sign-in. It does not need to explain return format because an output schema exists.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the account fields returned and followed by the authentication prerequisite. Every sentence contributes useful information with no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only account tool with an output schema and rich annotations, the description is nearly complete: it explains what is returned and the sign-in requirement. The only minor gap is explicit usage guidance about when an agent should call it.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents context, llm_model, and conversation_id. The description adds no parameter-level meaning beyond the schema, which is acceptable given full coverage but not above baseline.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names the exact resource—the signed-in user's account—and enumerates the returned values: plan, credit balance, next resets, and download quality. An agent can immediately tell this is the account-information tool rather than an image, video, search, or license tool.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by stating the tool returns plan and credit information, and it notes the sign-in prerequisite. However, it does not explicitly say when to call this versus other tools or when not to call it, leaving the agent to infer usage from the purpose.

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