+]Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare a non-read-only, open-world, non-idempotent write; the description adds the material detail that this is an 'external write' requiring prior authorization, which annotations do not convey. It stops short of warning about duplicate posts or what happens on rejection.
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 sentences, no filler, with the 'FAST PATH after read_song' trigger front-loaded before the constraint. Every clause carries information an agent needs.
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 5-parameter OpenWorld write with no output schema and no schema descriptions, the definition covers the preconditions well but says nothing about the response (voice id, moderation state) or how this relates to validate_quick_voice. Adequate to invoke, thin on consequences.
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?
With 0% schema coverage, the description is the only place semantics appear, and it does clarify that quoted_line must be an 'exact lyric quote' and that only song, quoted_line, and interpretation should be supplied (silently excluding model and reply_to). The two unmentioned parameters and their purpose remain completely unexplained.
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?
States a specific verb and resource ('publish one exact lyric quote and a specific interpretation') and frames it as the 'FAST PATH after read_song', which implies a slower alternative exists. It does not name submit_voice or validate_quick_voice, so the sibling differentiation is only implicit.
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?
Gives a clear activation condition ('after read_song') and an explicit restriction ('use it only when already authorized'). It never names the alternative tool an agent should pick when the precondition isn't met, so the when-not routing is left inferential.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
