cache_recent_entries

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

No annotations provided, so description bears full burden. Does not disclose whether caching is idempotent, overwrites existing data, or what 'recent' means. Lacks behavioral details beyond basic fetch-and-save.

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?

Extremely concise (one sentence), but at the cost of missing essential detail. Front-loaded with purpose but inadequate for effective tool invocation.

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?

Fails to define 'recent', explain return value (despite output schema existence), or distinguish behavior from siblings. Incomplete for a tool with 3 optional parameters and many related alternatives.

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 0%, and the description adds no information about any parameter. 'limit', 'journal', 'beforedate' are left unexplained despite being crucial for usage.

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?

Clearly states the action 'Fetch... and save' and the resource 'recent LiveJournal entries'. Differentiates from siblings like 'cache_entry' (single entry) and 'cache_entries_for_date' (specific date).

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. With many sibling caching tools, explicit context for selection is missing.

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