expand_memory

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

No annotations are provided, so the description carries the full burden. It only mentions retrieving and expanding content without disclosing any behavioral traits such as whether the operation is idempotent, requires authentication, modifies state, or has rate limits. Critical behavioral context is missing.

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 short sentence with a 'Phase 3:' prefix, making it efficient. However, it may be too brief, sacrificing informative content for brevity. It earns a 4 for being concise, though not maximally helpful.

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 no output schema and the complexity of the tool (3 parameters, potential side effects), the description fails to explain what the expanded content looks like, whether it modifies state, or how it integrates with other tools like 'memory_loading'. It is incomplete for an AI agent to fully understand the tool's role.

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 100% description coverage for all three parameters. The description adds no additional meaning beyond the schema, so the baseline score of 3 is appropriate. The description does not clarify parameter interactions or constraints.

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 tool retrieves and expands stored content using an expandable ID from a tiered response. The verb 'retrieve and expand' and the specific resource are identified, but it lacks explicit differentiation from similar sibling tools like 'expand_analysis_section' or 'memory_loading'.

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 only labels the tool as 'Phase 3', implying a sequential process but provides no explicit guidance on when to use this tool versus alternatives. No when-not-to-use conditions or alternative tool names are mentioned.

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