uvcs_style_init_prepare

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

The description says the tool creates a file and exposes an `overwrite` parameter for replacing an existing style.json, while annotations declare readOnlyHint=true and destructiveHint=false. The write/possible-destruction claim conflicts directly with the read-only annotation, and no permission or side-effect detail resolves the inconsistency.

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 short sentences, front-loaded with the action and artifact, then workflow, then return value. No filler, though the middle 'Requires prepare/confirm' sentence could be folded in.

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?

Usefully discloses the short-lived confirmation token since there is no output schema, and flags the prepare/confirm pairing. But for a file-writing tool with no annotations support, it omits where the file is written, what happens to an existing file without overwrite=true, and whether the token is consumed by uvcs_style_init_confirm.

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 all five parameters (including the preset enum and overwrite warning) are already documented at field level. The description adds only an aggregate view of what the config covers, not parameter-specific meaning beyond the schema.

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 artifact (create .uvcs-mcp/style.json) plus the contents it encodes (branch naming, checkin message, release conventions). This clearly separates it from siblings like uvcs_style_rules (read rules), uvcs_style_setup_check (diagnose), and uvcs_style_init_confirm (apply).

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?

'Requires prepare/confirm' signals the two-step workflow and implies this tool is the first step, which is useful routing. However, it never says when to call this versus uvcs_style_setup_check or uvcs_style_rules, nor gives conditions for choosing a preset or deciding to overwrite.

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