create_entry

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

Annotations already declare destructiveHint=true, readOnlyHint=false, and openWorldHint=true, so the safety profile is covered structurally. The description adds nothing beyond them: it does not say what kind of entry is created, where it is stored, whether creation is reversible, or what the caller needs to supply.

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?

It is a single front-loaded sentence with no padding, so it is concise. But the brevity comes at the cost of under-specification rather than efficiency, and it omits the parameter and behavioral context an agent would need.

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?

This is a destructive, open-world mutation tool with no output schema and 0% schema description coverage, so the description carries the full explanatory burden. One sentence covering neither the created resource's nature, the visibility semantics, nor any post-creation behavior leaves it materially incomplete.

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 0%, so the description must carry the burden for the two required parameters, and it does not: neither 'body' nor 'visibility' (a public/private enum) is explained or given semantics. The phrase 'for the authenticated owner' only loosely gestures at ownership scoping and adds no usable meaning about visibility values.

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 gives a verb+resource ("Create an entry") and a scope ("for the authenticated owner"), which is better than a tautology. However, "entry" is undefined in a sibling set that already contains create_changelog_entry and create_comment, so an agent cannot tell which entry type this creates or how it differs from those siblings.

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 guidance, no prerequisites, and no mention of alternatives such as create_changelog_entry or create_comment. The only implied context is that the entry is created for the authenticated owner, which is a scope note rather than usage guidance.

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