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

Adds substantial context beyond the annotations: a billing model (1 credit = 1 CAD cent, charged only on success), validation-before-billing, and an explicit return shape. The word 'Writes' could momentarily read as a disk write against readOnlyHint=true, but the following clause ('save content at path') makes clear nothing is persisted. Not a contradiction, but slightly loose phrasing.

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?

Three tight sentences: purpose first, return/save instruction second, pricing and validation third. No filler. A slightly clearer lead-in separating 'generates' from the save action would sharpen it, but nothing needs cutting.

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?

With no output schema, the description carries the return contract and does so explicitly (path, content, usage plus where to save). It also covers cost and failure behavior, which an agent needs before spending credits. Nothing material is missing for correct invocation.

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%, so every parameter (name, description, allowedTools, argumentHint) is already documented with types, patterns and limits. The description only alludes to frontmatter and $ARGUMENTS without adding syntax or format detail beyond the schema. Baseline 3 is warranted.

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?

Names a specific verb+resource: producing a ready-to-save Claude Code slash command file with frontmatter, $ARGUMENTS and a step outline. No sibling in the list generates slash commands, so the distinction is immediate. The output triple { path, content, usage } further pins down what the tool produces.

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 makes the use case obvious (generate a slash command file to save under .claude/commands/<name>.md) and states that malformed input is rejected before billing. It never names an alternative or a when-not-to-use, which for a narrowly scoped generator is a minor gap rather than a blocking one.

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