studio_character_list

Read-onlyIdempotent

List your studio_character rows (newest first).

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,
  "jsonrpc": "2.0",
  "method": "tools/call",
  "params": {
    "arguments": {},
    "name": "studio_character_list"
  }
}

Input Schema

Name	Required	Description	Default
`limit`	No	Page size 1-200. Omit BOTH limit and cursor for the legacy bare-array first page of 200; pass either to get { items, next_cursor, limit } instead.
`cursor`	No	Opaque page cursor — pass a previous response's next_cursor verbatim. null next_cursor means no further pages.

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered. The description contributes the ordering guarantee (newest first), which is genuinely beyond the annotations, but says nothing about scoping to the caller's tenant or about the two response shapes.

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?

A single front-loaded sentence with no wasted words. It is arguably too terse given how much behavior the schema hides, but it is efficient and clear.

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

Completeness3/5

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

With no output schema, the description should signal the return shape, and it does not — an agent omitting both params gets a bare array while passing either yields an envelope. The schema carries that detail, so the gap is moderate rather than fatal.

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%; both limit and cursor are fully documented in the schema, including the unusual legacy bare-array behavior. The description adds no parameter meaning, 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?

States a specific verb and resource ('List ... studio_character rows') and adds the sort order ('newest first'), which lets an agent distinguish it from studio_character_read/create/update/delete. It does not name an alternative explicitly, 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 Guidelines2/5

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

There is no statement of when to use this instead of studio_character_read or of any prerequisites. The only usage-relevant detail, the legacy vs paginated response modes, lives in the schema rather than the description.

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