memory_read

Retrieve the exact current state of a memory, with an option to include its complete version history.

Instructions

Read one memory's exact current state, optionally including every immutable version.

TDQS

B3.2/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'read' implies no mutation, the description does not explicitly confirm read-only behavior, nor does it mention authentication requirements, error handling, or whether calling with a non-existent memory_id has consequences. This is a significant gap.

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?

The description is a single, front-loaded sentence with no redundant words. It efficiently communicates the core function and the optional parameter.

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 tool with two parameters and an existing output schema, the description covers the essential purpose and the optional flag. It is complete enough for most use cases, though it could mention that memory_id is required and what happens if it is invalid.

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?

The input schema has 0% description coverage, so the description must compensate. It adds meaning by explaining that memory_id identifies a single memory and include_history retrieves 'every immutable version.' This is helpful but limited; more details on the format of history or default behavior would improve clarity.

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 clearly states the tool reads one memory's current state with an optional history flag. The verb 'Read' and resource 'memory's exact current state' are specific. However, it does not distinguish itself from sibling tools like memory_history or memory_search, which could have overlapping purposes.

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 guidance on when to use this tool versus alternatives like memory_search for finding memories or memory_history for viewing versions. The description lacks context on prerequisites or scenarios where this tool is preferred.

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