delete_saved_horoscope

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

No annotations provided, so description carries full burden. Discloses destructive irreversible action, local execution, no auth/rate limits, side effects (permanent deletion), and error conditions. Full transparency.

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?

Well-organized with clear sections (purpose, comparison, side effects, prerequisites, parameter guidelines, output/errors). Front-loaded key info. Slightly verbose in sections but overall concise for the detail provided.

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 simple delete tool with 1 parameter and no output schema, description covers all needed context: purpose, usage, behavioral traits, parameter meaning, error messages. No gaps given tool complexity.

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?

Single parameter horoscope_id. Schema only gives type and title (0% schema description coverage). Description adds 'unique integer ID of the saved database record to delete (required)', which clarifies its role but could include constraints like minimum value or format.

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 action (delete), resource (saved horoscope record), and distinguishing details (by ID, local SQLite). Contrasts with siblings list_saved_horoscopes and get_saved_horoscope, making purpose unmistakable.

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?

Explicitly says when to use (clean up, delete unwanted), when not (use list/get instead), and prerequisites (record must exist). Provides clear guidance on alternatives.

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