memory_list

Read-onlyIdempotent

List memories with filters (tags, kind, canon_status, collection, session, confidence range, tag facets). Read-only. Returns { items, total }.

Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

Input Schema

Name	Required	Description	Default
`kind`	No	Filter by memory kind
`sort`	No	Sort field	updated_at
`tags`	No	Filter by tags (AND semantics by default)

`collection`	No	Filter by collection slug or ID
`session_id`	No	Filter by interaction session
`canon_status`	No	Filter by canon status
`updated_after`	No	Only memories updated after this ISO 8601 datetime
`max_confidence`	No	Maximum confidence as an integer percentage from 0 to 100

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, and the description's 'Read-only' merely restates that. The return shape { items, total } is extra context, but the output schema exists and already covers return values, so added behavior disclosure is thin.

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?

Three short, front-loaded sentences with no wasted wording. Minor redundancy: 'Read-only' duplicates the annotations and the { items, total } return note duplicates the output schema.

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?

For a 20-parameter, all-optional listing tool with full schema coverage, a complete output schema, and rich annotations, the description is adequate: it signals the intent, the filter breadth, and the safe read nature. The main gap is the absence of any routing signal against memory_search and memory_recall.

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 20 documented parameters, so the baseline of 3 applies. The description lists filter families (tags, kind, canon_status, collection, session, confidence range, tag facets) but adds no semantics beyond the schema, and omits sort, order, limit, and offset entirely.

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?

The description opens with a specific verb and resource ('List memories') and enumerates the main filter families, so the operation is unambiguous. However, it never differentiates itself from the overlapping siblings memory_search and memory_recall, which an agent would also consider for retrieval.

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

Usage Guidelines2/5

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

There is no when-to-use or when-not-to-use guidance and no mention of alternatives. With memory_search and memory_recall present as siblings with heavily overlapping retrieval semantics, the agent is left to infer that this tool is the enumerate-and-paginate path.

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