Book Lightyear Distributions

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

Annotations already provide destructiveHint=true, indicating data modification. The description adds value by noting the dry-run default and including tax handling. It does not detail reversibility or side effects, but the dry-run mention helps mitigate risk.

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?

Two concise sentences with no wasted words. The first sentence states the core action and scope, the second highlights the key dry-run behavior. Front-loaded with essential information.

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?

For a tool with 8 parameters and no output schema, the description adequately covers the main purpose and the dry-run feature. It lacks mention of prerequisites (e.g., needing a parsed statement) or return values, but these are partially covered by sibling tools and the schema.

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 coverage is 100%, so descriptions exist for all parameters. The description adds semantic context by naming distribution types (dividend, interest, reward) not in schema, but does not significantly elaborate on parameter usage beyond defaults.

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 specifies the verb ('Create journal entries'), resource ('Lightyear dividend, interest, and reward distributions'), and scope ('including withheld tax'). It distinguishes from siblings like book_lightyear_trades (trades) and parse_lightyear_capital_gains (capital gains).

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?

The description states 'DRY RUN by default,' hinting at safe preview usage. However, it does not explicitly mention when to use this tool vs alternatives (e.g., for trades vs distributions) or any prerequisites.

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