nexo_memory_timeline

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

No annotations exist, so the description must carry the full burden. It states 'Return' but does not explicitly confirm read-only behavior, data volume limits, permissions needed, or side effects. The chronological ordering is implied but not detailed.

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 sentence, which is concise. However, it sacrifices necessary detail for brevity, leaving significant gaps. It would benefit from additional context while remaining succinct.

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 4 parameters, no output schema, and no annotations, the description is severely incomplete. It does not specify output format, pagination behavior, or how parameters interact, making it insufficient for an agent to reliably invoke the tool.

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 4 parameters (query, project_hint, time_range, limit) with 0% description coverage, and the description does not explain their purpose or usage. Without any parameter semantics in the description, the agent lacks critical information for correct invocation.

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 it returns a chronological timeline of Memory Observations v2, which indicates a specific resource and action. However, it does not differentiate from sibling tools like nexo_memory_observation_list, which may also return observations, leaving ambiguity about when to use this tool.

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?

No guidance is provided on when to use this tool versus alternatives such as nexo_memory_search or nexo_memory_observation_list. The description lacks context on typical use cases, prerequisites, or intended scenarios.

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