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

Annotations declare destructiveHint=true and readOnlyHint=false, but the description never explains what is destructive here — most likely that setting context overwrites or replaces an existing stored context. It also omits persistence scope (per account? per conversation?) and any auth/plan prerequisites beyond the free-tier note. The only value added over annotations is the free-tier restriction.

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?

Two short sentences, front-loaded with the purpose and ending with the eligibility constraint. Minimal waste, though "so Opsphere can personalize responses" is slightly vague about the actual effect of storing context.

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?

An output schema exists, so return-value explanation is not required. But for a destructive write tool with a free-form payload and an optional context_id that redirects where the write lands, the description leaves out the overwrite semantics and the relationship to get/close sibling tools that an agent needs before calling it.

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 description coverage is 100%, including a detailed context_id explanation (ctx_* Connection Hub context, omit to use active workspace), so the schema already carries the parameter burden. The description adds mild value by listing the kinds of content to put in the free-form `context` field, but nothing about format or length expectations beyond schema's Markdown note.

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 (store) and resource (your usual work context) plus concrete examples of what belongs in it: projects, providers, environments, naming conventions. The counterpart sibling ops_get_work_context is implicit in the naming but never named, so differentiation relies on the shared prefix rather than explicit contrast.

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?

"Free-tier plugin accounts only" is a real applicability gate that tells the agent when this tool is off-limits. However, there is no guidance on when to set context versus opening/closing an ops context (ops_context_open, ops_context_close) or on checking existing context first with ops_get_work_context — usage is implied, not directed.

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