TokenBel Financial Data

bond_list

Read-onlyIdempotent

List active BCSE exchange-listed bonds with optional filtering by securities issuer TokenBel internal id (parameter name: issuer_uuid) and today-trading flag. Use issuer_uuid from search_by_name results where entity_type="issuer". Supports cursor-based pagination.

Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	Max results (1-1000, default 50)
`is_trading`	No	Filter by is_traded_today flag: true means traded today, not historical liquidity
`cursor_uuid`	No	TokenBel internal identifier: opaque hexadecimal string, usually 8 characters such as "78c7e502"; despite uuid field/tool names, it is not an RFC UUID and normally has no hyphens. Pagination cursor id from next_cursor before the \| delimiter.
`issuer_uuid`	No	TokenBel internal identifier: opaque hexadecimal string, usually 8 characters such as "78c7e502"; despite uuid field/tool names, it is not an RFC UUID and normally has no hyphens. Filter by security_issuer id from search_by_name result with entity_type="issuer".
`cursor_created_at`	No	Pagination cursor datetime (ISO 8601)

TDQS

A3.5/5.0

Behavior3/5

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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered. The description adds that pagination is cursor-based and that results are limited to active listings, but the schema itself already documents the cursor parameters, so the incremental behavioral value is modest.

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?

The purpose is front-loaded in the first clause, followed by filter and pagination notes in two compact sentences. Nearly every phrase earns its place, though the parameter-name restatement adds minor redundancy.

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?

An output schema exists, so return values need not be explained, and the description covers purpose, filters, and pagination. It is largely complete for a read-only filtered-list tool, with only the sibling differentiation gap remaining.

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 all five parameters are already documented in the schema, establishing a baseline of 3. The description restates the issuer_uuid and is_trading filters and the search_by_name linkage, but adds little beyond what the schema descriptions already contain.

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 (List) plus resource and scope (active BCSE exchange-listed bonds), which is more precise than a generic list tool. It names its optional filters, but does not differentiate itself from the sibling company_bonds_list, leaving the agent to infer which bond listing to use.

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 gives a useful acquisition hint (take issuer_uuid from search_by_name results where entity_type="issuer"), which implies usage context. However, it offers no explicit when-to-use vs. when-not-to-use guidance or alternatives against company_bonds_list or share_list.

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