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

Goes well beyond the annotations: it discloses that shared rules are withdrawn on exclusion, that surviving shared rules are generalized so the originating business cannot be identified, and that Sergio notifies the owner after this owner-level change. Those are real consequences an agent should know before calling. The idempotency retry instruction partly restates the annotation and schema, which keeps it from a 5.

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?

Four short sentences, front-loaded with the core action and consequence before the retry and notification details. The phrase 'as the article's Toolshed sharing line does' is slightly oblique and the retry sentence duplicates schema text, but nothing is padded.

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 a mutating, idempotent, non-destructive toggle with no output schema, the description covers the state change, downstream effect on shared rules, anonymization, retry semantics, and the post-change owner notice. What remains thin is the identity/validation of sopId and any indication of what the call returns or errors on.

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 coverage is 50%: reason and idempotency_key are documented in the schema, while sopId and excluded are bare. The description implicitly conveys the excluded boolean's two directions and the notification consequence of reason, but never says what sopId identifies or how a missing/invalid article behaves. Adequate given the schema, but it does not fully close the coverage 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 concrete two-way action on a specific resource: exclude one handbook article from Toolshed sharing (withdrawing its shared rules) or include it again. The 'as the article's Toolshed sharing line does' clause anchors it to a visible UI control, which distinguishes it from archive_handbook_article and edit_handbook_article. It stops just short of naming those siblings explicitly.

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 rather than stated: the agent learns this mirrors the article's Toolshed sharing toggle and that retries must reuse the same idempotency_key. There is no explicit when-to-use/when-not guidance and no contrast with archive_handbook_article, which an agent could easily confuse with 'taking an article out of circulation'.

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