init_changelog

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It reveals the side effect of creating store and config files, and clarifies that Markdown is not yet created. However, it does not specify whether the tool is idempotent, what happens if files already exist, or required permissions.

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 sentence that is direct and front-loaded with the action ('Legt leeren Store und Config-Datei an') and adds a clarifying parenthetical about Markdown timing. Every word earns its place with no redundancy.

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 an initialization tool with one optional parameter and an output schema, the description gives the core action and a key timing detail. However, it lacks guidance on format semantics and any preconditions or effects on existing data, making it only partially complete for an agent to use confidently.

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?

The description does not mention the 'format' parameter at all. The schema provides enum values (keep-a-changelog, conventional, smart) and a default of null, but no semantics for choosing between them. With 0% schema description coverage, this is a significant gap that the description fails to fill.

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 clearly states the tool creates an empty store and config file, with a specific note that Markdown is deferred until the first release. This distinguishes it from siblings like create_release or render_changelog, which handle later stages.

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?

No explicit guidance on when to use this tool versus alternatives. It does not mention that this should be run before other changelog operations, nor does it describe any prerequisites. The note about Markdown creation is a temporal hint but not a usage directive.

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