sync_entries

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

With no annotations, the description must fully disclose behavior. It only states a read operation, omitting details on side effects, authentication requirements, rate limits, or response format. This is insufficient for an agent to understand operational constraints.

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 a single, concise sentence that quickly conveys the core functionality. However, its brevity sacrifices parameter details and usage guidance that could be included without significant bloat.

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 tool has an output schema (which could explain return values) and moderate complexity (2 parameters), the description provides a basic understanding but omits important context like the format of the timestamp or how the output relates to other cache tools. It is minimally adequate.

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%, so the description must explain parameters. It hints that 'lastsync' is a timestamp but does not specify format or valid values. The 'journal' parameter is completely ignored. This adds minimal value beyond the schema structure.

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 specifies a clear action ('Read'), resource ('entries'), and condition ('changed since a LiveJournal sync timestamp'), effectively distinguishing it from sibling tools like get_entry or list_entries which do not reference synchronization or a timestamp.

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 is provided on when to use this tool versus alternatives such as cache_synced_entries or search_recent_entries. The description lacks any when/when-not instructions or references to other tools.

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