StockCake Account

get_account

Read-onlyIdempotent

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

Input Schema

TableJSON Schema

Name	Required	Description
`context`	Yes	In one sentence, what is the user trying to make or find?
`llm_model`	Yes	The 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_id`	No	Pass 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.

A3.7/5.0

Behavior4/5

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds value with the authentication requirement and the note that the host will prompt to sign in, which is exactly the kind of context annotations cannot express. It does not cover rate limits or failure modes, so not a 5.

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

Conciseness4/5

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

Two sentences with no filler; the returned data is front-loaded and the account prerequisite follows. The 'free / subscription / purchased' parenthetical earns its place by enumerating credit types, but the sentence is somewhat dense rather than optimally structured.

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?

With rich annotations, a 100%-covered schema and an output schema that carries the return shape, the description only needs to frame purpose and prerequisites, which it does. Nothing critical for invoking the tool is missing, though guidance against the adjacent get_license_info would make it fully complete.

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%, and all three parameters (context, llm_model, conversation_id) carry detailed inline descriptions, including the conversation_id continuity rule. The description adds nothing about parameters, so the baseline 3 applies.

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

Purpose4/5

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

The description names a specific resource (the signed-in user's plan, credit balance, reset dates, download quality and output formats), which unambiguously separates it from the image/video generation and search siblings. It never explicitly contrasts itself with the nearest sibling, get_license_info, so it falls short of a 5.

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?

It states a prerequisite (a free StockCake account, with the host prompting sign-in), which is useful context, but it never says when to reach for this tool versus get_license_info or list_models. Usage is only implied by the data it returns.

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