get_entries_for_date

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

No annotations provided. Description implies non-destructive read operation, but does not elaborate on authentication needs, return format, or any side effects. The output schema exists but is not referenced.

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?

Single sentence, front-loaded with key information. No unnecessary words.

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?

Adequate for a simple read tool with an output schema. Could mention that it reads live data (as opposed to cached), but overall sufficient given the context.

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?

Adds format requirement for date parameter ('YYYY-MM-DD'), which is helpful given 0% schema description coverage. However, the journal parameter has no added meaning beyond the schema.

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 'Read LiveJournal entries for one date in YYYY-MM-DD format', specifying the action (read), resource (LiveJournal entries), and scope (one date). Distinguishes from siblings like get_entry or cache_entries_for_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 like cache_entries_for_date or search_recent_entries. Does not mention any prerequisites or contexts.

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