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

Annotations already set readOnlyHint=false and destructiveHint=false, so the write/safe profile is covered; the description adds real value with auth requirements (owners/admins), the max-40-steps cap, the max-10-active limit and its limit_reached error, and archive/restore semantics. It omits the confirm_id two-phase preview/commit flow revealed in the schema, which is a meaningful behavioral gap.

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?

Terse, front-loaded declarative clauses with zero filler; the create/update rule leads and constraints follow. Every sentence earns its place.

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 mutation tool with no output schema, it covers auth, limits, error behavior, and key param semantics. The notable omission is the confirm_id preview-token workflow, which the agent must implement to actually persist the write, so it is not fully complete.

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?

With 44% schema coverage across 9 params, the description compensates well by defining steps shape and cap, outpost_ids sourcing (from list_clients) and omit-equals-all default, and status active/archived behavior. It does not explain confirm_id, schedule, source, or description, leaving several params undocumented in both places.

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 (create/update) and resource (SOP) and disambiguates the two modes via the presence or absence of sop_id. An agent can distinguish it from siblings like get_sop and list_sops without opening a schema.

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 says when to create vs update (with/without sop_id), who may call it (owners/admins), and how to archive/restore via status. Missing only explicit routing to sibling read tools (get_sop/list_sops), so it falls short of a 5.

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