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 describes system tracking (priorities, states, relationships) and thought capabilities (insights, cross-references), but it fails to disclose critical behavioral traits such as whether operations are read-only or destructive, authentication needs, rate limits, or how data is persisted. This leaves significant gaps for an agent to understand the tool's 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 appropriately sized and front-loaded with a purpose statement, followed by bullet points and commands. Each sentence earns its place by detailing capabilities and usage, though it could be slightly more streamlined by integrating the commands into the flow rather than as a separate section.

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 complexity (9 parameters, nested objects, no output schema) and lack of annotations, the description is incomplete. It covers basic functionality but misses critical context like return values, error handling, or operational constraints, making it inadequate for an agent to fully understand how to invoke and interpret results from this 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?

Schema description coverage is 100%, so the schema already documents all 9 parameters thoroughly. The description adds no specific parameter semantics beyond what the schema provides, such as explaining how 'confidence' scores affect operations or the meaning of 'crossRefs' in practice. Baseline 3 is appropriate as the schema does the heavy lifting.

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 states the tool is for 'managing multiple branches of thought with insights and cross-references,' which gives a general purpose but lacks a specific verb and resource. It doesn't distinguish from siblings (none provided), but the purpose remains somewhat vague without concrete examples of what 'managing' entails beyond the listed commands.

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 implies usage through the 'Commands' section (list, focus, history), suggesting when to use these specific actions, but it lacks explicit guidance on when to use this tool overall versus alternatives (none provided) or any exclusions. The context is implied rather than clearly stated.

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