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

Annotations already cover the safety profile (readOnlyHint=true, destructiveHint=false, openWorldHint=true), so the bar is lower. The description does add real value by disclosing tier-dependent output (paid plans return a count and list of removed characters) and a cost of 1 credit, but it never says whether punctuation is deleted outright or replaced with spaces, which materially changes the result.

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?

The opening 'Remove Punctuation: Remove Punctuation strips...' redundantly restates the name and title back to back, wasting the most prominent position. The remaining two sentences are efficient and the cost note is well placed at the end.

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 one-parameter tool with annotations and an output schema, most structured burden is already covered. However, the description leaves an important behavioral gap: whether the punctuation set includes non-ASCII marks, apostrophes, and symbols, and whether removed characters leave gaps or are replaced by spaces.

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?

There is a single parameter with 100% schema description coverage including an example, so the schema already does the heavy lifting and the baseline is 3. The description's 'any submitted text string' adds no syntax, encoding, or formatting detail beyond what the schema provides.

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 states a specific verb and resource: it 'strips punctuation marks from any submitted text string and returns the cleaned text.' That is clearly distinguishable from most siblings, though it never contrasts itself with near-neighbors like Slugify or TextStyler, which also transform text.

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 when-to-use or when-not-to-use guidance and no named alternative. The phrase 'any submitted text string' implies broad applicability but does not tell an agent when this is the right choice over similar text-normalization tools in the catalog.

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