get_pronunciation_dictionary_version_pls

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

Annotations already establish that this is a safe, idempotent, read-only operation, so the safety profile is covered. The description adds one piece of genuinely useful behavioral context — that the return artifact is a PLS file (lexicon format) rather than JSON — but says nothing about size, encoding, or how rules are represented. Adequate but thin beyond the annotations.

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?

A single short, front-loaded sentence with no filler, which is appropriate for a simple getter. The choppy capitalization ('Get A Pls File') slightly hurts readability but costs no tokens.

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 two-parameter read-only fetch with full schema coverage and safety annotations already present, the description covers the essential missing piece: the nature of the returned artifact (a PLS file). Nothing critical about invocation is absent, though a note on file size or rule structure would have fully closed the gap.

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 100% (both dictionary_id and version_id are documented in the schema), so the baseline is 3. The description adds no further meaning about parameter format or expected values, and it does not need to.

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 names a specific verb ('Get') and resource (a PLS file containing a pronunciation dictionary version's rules), so the basic operation is inferable. However, it does not differentiate from siblings such as get_pronunciation_dictionary_metadata or get_pronunciation_dictionaries_metadata, and the phrasing is awkward enough to read as a restatement of the name rather than a distinct clarification.

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?

There is no indication of when this tool should be used instead of the metadata siblings, nor any prerequisites (e.g., that a valid dictionary_id/version_id pair must already exist). Given roughly a dozen pronunciation-dictionary-related siblings, this absence leaves the agent to guess.

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