set_status

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

With no annotations, the description carries the full burden. It does disclose that this is a state mutation and that the comment is optional and handled atomically in the same operation, plus a useful authoring convention for closing comments. It omits permissions, reversibility, and what happens to an existing comment on status change.

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?

Two tight sentences with the core verb/state information front-loaded and no filler. The second sentence adds a convention rather than restating the first, though it is arguably style guidance rather than invocation-critical detail.

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?

No output schema or annotations exist, so the description must stand alone. It covers status and comment adequately but says nothing about the required id, the mutation's effects, or the return result, leaving the definition only minimally viable for a 3-parameter mutation tool.

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 compensate. It usefully enumerates the two valid 'status' values and explains 'comment' semantics and its optional nature, but the required 'id' parameter is completely unaddressed, leaving a real gap.

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 action pair (open/close) on a specific resource (an entry) and enumerates the accepted status values inline. However, it never distinguishes itself from siblings like 'comment' or 'edit_body', which overlap with the optional-comment behavior it advertises.

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?

Usage is implied by 'Open or close an entry' and the note that a comment can be supplied in the same operation — a subtle hint that this can replace a separate comment call. There is no explicit when-not guidance and no named alternative among the many siblings (comment, edit_comment, edit_body).

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