getDefaultIcons

Read-only

Retrieve a list of Icons from the default context for full-collection or batch requests; use single-item lookup for one Icon by ID.

Instructions

Returns a list of Icons from the default context. Cardinality: targets the full collection or a batch. For a single item by ID, use getDefaultIcon instead.

Input Schema

Name	Required	Description	Default
`fields`	No	Sparse fieldset selector: an object keyed by resource type (e.g. `workitems`) whose value is a comma-separated list of attribute names to return (e.g. `id,title,status`), reducing payload size. Omit to return the default field set.
`max_items`	No	Collect up to this many results across pages (maximum 1000). Omit to fetch only the requested page, as before.
`page_size_`	No	Maximum number of items to return in this page (e.g. `100`). Use together with `page[number]` to paginate through a large result set.
`page_number_`	No	1-based page number to fetch when the result set is paginated (e.g. `2` for the second page). Combine with `page[size]`; omit to fetch the first page.
`response_format`	No	Response detail level. concise removes redundant HTML and JSON:API metadata and may use a small default fieldset on large lists; detailed preserves the complete response. Defaults to detailed.	detailed

Output Schema

Name	Required	Description
`data`	No

A4/5.0

Behavior4/5

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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description adds genuinely useful scope context with 'Cardinality: targets the full collection or a batch', telling the agent this is not a single-item lookup. It says nothing about pagination behavior or result ordering, but the schema parameters cover paging.

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 what is returned and its scope, followed by the sibling routing rule. Nothing is repeated from the schema and no sentence is 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?

With an output schema present, annotations covering safety, and full parameter documentation, the description only needs to establish scope and routing, which it does. The one remaining gap is that it never clarifies the default-vs-global-vs-project icon hierarchy that the sibling list makes ambiguous.

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%, with `fields`, `max_items`, `page_size_`, `page_number_` and `response_format` all documented in the schema including the concise-vs-detailed tradeoff. The description adds no parameter-level meaning, so the baseline of 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 ('Returns a list of Icons') plus the scope ('default context') and cardinality, so the agent knows it is a collection read. It explicitly separates itself from the singular `getDefaultIcon`, but does not distinguish itself from the other close siblings `getGlobalIcons` and `getProjectIcons`.

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?

Gives an explicit routing rule: 'For a single item by ID, use `getDefaultIcon` instead.' That is a real when-not condition naming the alternative. It stops short of saying when to prefer this over the global or project icon variants, so the exclusion set is incomplete.

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