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

With no annotations and only the phrase 'with file stats and metadata,' the description conveys a read-only listing operation but does not disclose access needs, sort details, permissions, potential network access, or other side effects.

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?

A single concise sentence fully conveys a clear scope for a zero-argument tool; no wordy details or redundancy.

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?

With an output-schema available, zero parameters, and no nested objects, the description completely defines a simple listing operation. It lacks alternate-tool guidance and explicit return shape, but the output schema and simplicity give enough context for successful selection.

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 tool accepts zero parameters, and its empty input schema is fully documented; there are no parameter semantics to describe, so the baseline is appropriate (no penalties).

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?

Description uses an explicit verb 'list' with a specific resource ('all indexed framework/library docsets') plus qualifiers ('in ~/.agents/', 'with file stats and metadata'), clearly distinguishing it from sibling tools that search, fetch, or sync.

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?

It provides no explicit guidance on when to choose this tool over siblings like search_docs or list_catalog, though the name and listing-specific wording imply a browsing/listing use case.

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