Project Digest

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

Annotations indicate read-only, non-destructive, and idempotent behavior. The description adds 'loop' but does not explain what the loop does or any side effects. It fails to add meaningful behavioral context beyond what annotations already provide, and the truncation hinders transparency.

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 extremely short but incomplete due to truncation (ends with '...'). It is not front-loaded with useful information and fails to convey complete meaning concisely.

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?

Despite having no parameters and no output schema, the description is severely incomplete. It does not explain what the tool produces, what the loop accomplishes, or how it relates to 'Project Digest'. The tool's purpose remains unclear.

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?

There are zero parameters in the input schema, so schema description coverage is 100%. The baseline for no parameters is 4. The description does not need to explain parameters, but could clarify the absence of required inputs.

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 'semantic-search the user's indexed Apple data for a topic, then loop ...' is incomplete and vague. It mentions a specific verb and resource but is truncated, leaving ambiguity about what the tool actually does. The title 'Project Digest' suggests a different purpose, and there is no differentiation from siblings like 'semantic_search'.

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 on when to use this tool versus alternatives such as 'semantic_search' or 'scan_notes'. The partial description implies it performs a semantic search and then loops, but no context for appropriate usage is provided.

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