List Circuits

netbox_list_circuits
Read-onlyIdempotent

List provider data links (circuits) from NetBox with pagination and filters by provider, type, status, tenant, or text search.

Instructions

List circuits (provider data links) from NetBox.

Supports pagination and filtering. Common patterns:

  • Discovery: call with no filters to browse the first circuits.

  • Lookup by id: use netbox_get_circuit instead when you already have an id.

  • Narrow scan: combine 'q' (fuzzy text) with resource-specific filters below.

Pagination:

  • 'limit' (max 1000, default 50) and 'offset'. Response includes 'has_more' and 'next_offset'.

  • Large list responses auto-truncate to keep under the character limit; keep calling with next_offset to continue.

Resource-specific filters:

  • cid:

  • provider_id:

  • type_id:

  • status:

  • tenant_id:

Universal filters:

  • q (string) Fuzzy text search across searchable fields.

  • tag (string[]) AND-filter by tag slugs.

  • created_after (date) ISO-8601 lower bound on 'created'.

  • created_before (date) ISO-8601 upper bound on 'created'.

Returns: Markdown summary (default) or JSON with shape: { total, count, offset, limit, items: [...], has_more, next_offset? }

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
qNoFuzzy full-text search across the object's searchable fields (name, description, etc.).
cidNo
tagNoFilter to objects that have ALL of these tag slugs. Repeat for multiple tags (AND semantics in NetBox).
limitNoMaximum number of items to return per page (1-1000, default 50).
offsetNoNumber of items to skip for pagination. Use next_offset from a previous response.
statusNo
type_idNo
tenant_idNo
provider_idNo
created_afterNoISO-8601 date; only return objects created on or after this date (e.g. 2024-01-01).
created_beforeNoISO-8601 date; only return objects created on or before this date.
response_formatNoOutput format: 'markdown' (default, human-readable) or 'json' (full structured payload). Use 'json' when chaining follow-up tool calls.markdown
Behavior5/5

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

Annotations already indicate read-only, open-world, idempotent, and non-destructive. The description adds valuable behavioral details: pagination mechanics (limit/offset, has_more/next_offset), auto-truncation for large lists, and response format options. No contradictions with annotations.

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?

Well-structured with sections (purpose, common patterns, pagination, filters, returns). Every sentence is useful and front-loaded with key information. No redundancy or 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?

Given 12 parameters (0 required) and no output schema, the description is quite complete. It explains the return shape (total, count, etc.) and pagination. However, it lacks details on the default ordering of results and doesn't describe error conditions. Still, comprehensive enough for an agent to use correctly.

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

Parameters4/5

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

Schema description coverage is 58% (low), but the description compensates by explaining all resource-specific filters (cid, provider_id, type_id, status, tenant_id) and universal filters (q, tag, dates) with details like fuzzy search, AND semantics, and ISO-8601 format. It also covers pagination parameters. A slight deduction because some parameter descriptions (e.g., cid, status) are minimal in the description, but overall adds significant value.

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 'List circuits (provider data links) from NetBox' with a specific verb and resource. It distinguishes itself from sibling netbox_get_circuit by noting 'use netbox_get_circuit instead when you already have an id.' This leaves no ambiguity about the tool's purpose.

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

Usage Guidelines5/5

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

Explicitly provides common patterns: Discovery (no filters), Lookup by id (use netbox_get_circuit), and Narrow scan (combine filters). It also details pagination usage. This gives clear when-to-use and when-not-to-use guidance.

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