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

Beyond the destructiveHint=true annotation, it discloses the destructive mechanism precisely: the three arguments are the WHOLE list and replace the previous one. It adds notification and one-reminder-in-two-working-days behavior, that marks are preserved when the list is emptied, and the authorization requirement (project lead, company owner or admin). It does not say what the response looks like or whether partial failure is possible, so not a full 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?

The replacement rule and the get_wiki_page_reading prerequisite are front-loaded, and almost every clause carries information an agent needs. It is dense and somewhat run-on, with a couple of clauses packed together (notification + reminder + askAgain) that could be separated, but there is no filler.

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 destructive, permission-gated mutation with no output schema, the description covers the authorization gate, the replacement semantics, the notification/reminder effects, the reversibility caveat (marks kept), and the alternate askAgain path. Nothing an agent needs in order to call it safely is missing.

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 already 100%, yet the description still adds real semantics: 'users' entries must each be able to read the page, 'members: true' is dynamic membership ('whoever they are on the day'), and 'askAgain: true' overrides the list rather than replacing it. The only weak spot is that the id parameter gets nothing 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 resource — setting who a wiki page is required reading for, plus the notification side effect. It is clearly distinguishable from get_wiki_page_reading (read the current list) and mark_wiki_page_read (mark one's own read), both of which appear among the 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?

Explicitly tells the agent to read the current list with get_wiki_page_reading first and pass back what should stay, which is the key prerequisite for a full-replacement tool. It also names the alternative mode (askAgain: true) and the switch-off case (empty list).

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