List collections

list_collections

Read-only

List the authenticated user's AgentMash collections with ids, names, sources and saved-post counts. Use to find a collection to browse. Includes imported folders and lists when available. Empty collections are omitted unless include_empty is true. Does not create or change collections. Read-only; calls count toward account usage and appear in the user's activity log.

A4.1/5.0

Behavior4/5

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the description earns credit for additional context: calls count toward account usage and appear in the activity log, plus the default omission of empty collections.

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?

Front-loaded with the resource and return shape, then usage, edge case, and constraints; each sentence carries information. Slightly dense at five sentences but no wasted text.

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 no output schema, the description helpfully enumerates returned fields and covers the empty-collection edge case and usage-cost note. The description is adequate, with only minor gaps such as pagination or ordering behavior.

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 coverage is 100% and the single parameter is documented in the schema. The description restates include_empty's effect, adding only the clarification that "empty" means no saves, which is marginal value over the schema.

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 names a specific verb and resource (list collections) and enumerates the returned fields (ids, names, sources, saved-post counts), which plainly distinguishes it from get_collection_saves, which browses within a collection.

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?

"Use to find a collection to browse" gives explicit usage context and implicitly routes the agent to get_collection_saves. "Does not create or change collections" rules out mutation, though no sibling is named explicitly.

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