Delete Memory

delete_memory

Remove specific stored information by ID when users request to forget data, managing memory persistence in AI applications.

Instructions

Delete a specific memory by ID. Use when a user asks to forget something.

A3.6/5.0

Behavior2/5

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

With no annotations provided, the description carries the full burden of behavioral disclosure. While it indicates this is a destructive operation ('Delete'), it lacks crucial details such as whether deletion is permanent, requires specific permissions, has side effects (e.g., cascading deletions), or provides confirmation feedback. For a mutation tool with zero annotation coverage, 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 extremely concise with two sentences that directly address purpose and usage. Every word earns its place, with no redundant information or fluff, making it easy to parse quickly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given this is a destructive mutation tool with no annotations and no output schema, the description is incomplete. It doesn't address critical behavioral aspects like permanence, permissions, error handling, or what happens post-deletion. For a tool that permanently removes data, more context is needed to ensure safe and correct usage.

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 schema description coverage is 100%, with the single parameter 'id' fully documented in the schema as 'The memory ID to delete'. The description adds no additional parameter semantics beyond what the schema provides, so it meets the baseline for high schema coverage without adding 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 the specific action ('Delete') and resource ('a specific memory by ID'), distinguishing it from sibling tools like 'list_memories', 'store_memory', or 'update_memory'. It precisely communicates the tool's function without ambiguity.

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?

The description provides clear context for when to use the tool ('when a user asks to forget something'), which helps differentiate it from read-only siblings like 'list_memories' or 'search_memories'. However, it doesn't explicitly state when NOT to use it or mention alternatives like 'update_memory' for modifying instead of deleting.

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