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

Annotations already flag destructiveHint=true and readOnlyHint=false, and the description aligns by saying it 'Removes their access.' It adds useful context about manager approval, from-now-on vs just-once approval behavior, and the UI confirmation card semantic, none of which are inferable from the schema or annotations.

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 description is short and front-loaded with the core action, followed by a compact approval-workflow note. The bracket text is dense but each clause carries guidance; minor jargon like 'write-tier' and 'the card is the yes' keeps it from a perfect score.

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?

Annotations cover the destructive profile, the schema fully documents the parameters, and the description covers the approval and no-re-ask behavior, making the tool callable. It does not state how the commitment is identified when only unshare_email is required, but the other fields are schema-documented and the action is simple.

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?

All four parameters are already described in the input schema (100% coverage), so the description does not need to repeat them. It adds no parameter-level meaning beyond 'with someone' loosely corresponding to unshare_email, and provides no extra guidance on commitment_id vs title_search or companyId.

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 uses the verb 'Stop sharing' with the direct object 'a commitment' and clarifies the consequence ('Removes their access'). This clearly differentiates it from the inverse sibling share_commitment and from resource-different siblings like unshare_knowledge.

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?

The bracketed text explicitly says to 'Call it on the first clear ask' and warns 'do not re-ask in chat', giving both a trigger condition and a negative instruction. It also explains approval variants, but it does not name an alternative tool or explicitly define when not to use this tool beyond the chat re-ask warning.

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