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

Far exceeds the annotations: it discloses the two-phase preview/confirm protocol, that the first call changes nothing, the contents of the preview (summary, changes, warnings, token), single-use and short expiry of the token, stale_revision handling, replay semantics (status applied, replayed: true, ids returned instead of acting twice), and that a refused call does not consume the token. It also carries an explicit injection warning about CRM field values. Nothing contradicts the annotations (non-read-only but non-destructive, idempotent via replay).

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?

Purpose is front-loaded in the first sentence and the protocol follows in logical order. It is verbose, with several sentences devoted to anti-injection guardrails and replay/refusal edge cases, but almost all of it is load-bearing for a confirmation-token workflow; only mild tightening is possible.

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 exists, yet the description fully explains what the preview returns (summary, changes, warnings, confirmationToken) and what a replayed call returns (status applied, replayed: true, change ids). Combined with the annotations, an agent has everything needed to invoke the tool correctly across the preview/apply lifecycle.

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 67%; confirmationToken and workspaceId already have schema descriptions. The description reinforces and extends the token semantics with lifecycle details the schema lacks (expiry, single use, replay, refusal), and implies workspace scoping for an administrative change. Only the required `name` parameter gets no added meaning beyond its length constraints.

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 — adds a failure-reason option members can pick when marking an activity as failed — and even specifies placement ('at the end of the list'). It is readily distinguishable from rename_activity_failure_reason and disable_activity_failure_reason, though it never names them explicitly, so it stops just short of 5.

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?

Gives a detailed procedural context: call first without confirmationToken to preview, show the summary and warnings, obtain explicit approval, then re-call with the token. It also flags this as a workspace-administration change. It does not, however, state when to prefer this over sibling operations (e.g. rename/disable), so the sibling-selection guidance is implicit.

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