b24_lists_get

Read-onlyIdempotent

Retrieve list definitions (IBLOCK_ID, NAME) for a given information-block type in Bitrix24. Use the returned IBLOCK_ID with b24_lists_element_list to read records.

Instructions

List the available Lists of a given type (lists.get).

Returns the list definitions (IBLOCK_ID, NAME, ...). Use an IBLOCK_ID with b24_lists_element_list to read its records.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
iblock_codeNoOptional list code to fetch a single list.
webhook_urlNoOverride the default incoming webhook for this call (https://<portal>/rest/<user_id>/<token>/). If omitted, uses personal_webhook, then the X-B24-Webhook HTTP header, then the BITRIX_WEBHOOK_URL env default.
iblock_type_idYesInformation-block type, e.g. 'lists' (portal lists), 'bitrix_processes' (workflows), 'lists_socnet' (group lists).
personal_webhookNoAct as a specific user (their personal incoming webhook). Takes precedence over webhook_url. Required to write to the portal under that user's permissions.

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint. Description adds that it returns list definitions, consistent with safe read operation. No additional behavioral traits like auth or rate limits, but annotations cover core safety.

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 purpose, includes practical usage hint. Every sentence adds value; no redundancy.

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

Completeness5/5

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

Given output schema exists and annotations cover safety, description adequately explains tool's function and output usage. Parameter descriptions in schema are thorough. Complete for the tool's complexity.

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 covers 100% of parameters with descriptions. Description does not add new parameter details beyond mentioning 'given type' for iblock_type_id. Baseline score justified.

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 clearly states it lists available lists by type, returns definitions (IBLOCK_ID, NAME), and distinguishes from sibling b24_lists_element_list by explaining how to use the output. Specific verb and resource with differentiation.

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

Usage Guidelines4/5

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

Provides clear context: lists of a given type with examples for iblock_type_id. Suggests using IBLOCK_ID with b24_lists_element_list. Does not explicitly mention when not to use or alternatives, but practical guidance is sufficient.

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