cache_synced_entries

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

With no annotations, the description fails to disclose side effects, overwrite behavior, or safety considerations. It only states the core action without behavioral context like whether it's safe to call repeatedly or what happens to existing cache.

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 single-sentence description is concise and front-loaded with key information. However, it could be expanded to include behavioral or parameter details without becoming verbose.

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 an output schema and sibling tools, the description provides insufficient context. It does not explain the output, prerequisites, or how this tool fits with related tools like sync_entries and get_cached_entry.

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 description mentions 'sync timestamp' mapping to 'lastsync' but does not describe its format or semantics. The optional 'journal' parameter is not mentioned at all. With 0% schema description coverage, more detail is needed.

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 fetches entries changed since a sync timestamp and saves them to the local SQLite cache. This distinguishes it from sibling tools like cache_entries_for_date (specific date) and cache_entry (single entry).

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 vs alternatives. The description does not mention when not to use it, prerequisites, or suggest other tools for different scenarios.

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