delete_memory

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. It states the tool deletes a memory, implying a destructive mutation, but doesn't cover critical aspects like whether deletion is permanent, requires specific permissions, has side effects (e.g., on related sessions), or returns confirmation data. For a destructive tool, this leaves significant gaps in understanding its behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, direct sentence with zero wasted words. It front-loads the key action ('Delete') and resource ('memory'), making it immediately scannable. Every word earns its place by contributing essential information without redundancy or fluff.

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

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

Given the tool's complexity (destructive operation with 1 parameter) and lack of annotations, the description is minimally adequate. The presence of an output schema reduces the need to explain return values, but the description doesn't address behavioral risks or usage context. It covers the basic 'what' but misses the 'how' and 'when,' leaving room for improvement in safety and clarity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

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 specifying that 'memory_id' identifies 'a specific memory,' clarifying the parameter's role. However, it doesn't explain what a memory ID is (e.g., format, source) or constraints (e.g., valid ranges), leaving the schema's bare type ('integer') as the only guidance. This partial compensation earns a baseline score.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Delete') and target resource ('a specific memory by its ID'), making the purpose immediately understandable. It distinguishes from siblings like 'list_memories' and 'save_memory' by focusing on deletion rather than retrieval or creation. However, it doesn't specify what constitutes a 'memory' in this context, which slightly limits specificity.

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

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

The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing memory ID), exclusions, or comparisons to siblings like 'save_memory' for creation or 'list_memories' for retrieval. Without this context, users must infer usage from the tool name alone.

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