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

Annotations already declare this is a non-read-only, idempotent, non-destructive, closed-world operation, so safety is covered. The description adds that activation applies to the current Progressive Discovery session, but does not say whether enabling replaces or augments the current tool set, whether 'pack' and 'tools' can be combined, or whether the change persists past the session.

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?

Front-loaded with the action and scope in one sentence, followed by a compact example. The example partly restates an enum value already visible in the schema, so it is slightly redundant but still cheap.

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?

With only two optional, fully documented parameters and a complete annotation set, this is close to sufficient. However, the key interaction — pack vs. tools, additive vs. replacing, and effect duration — is left unstated for a state-mutating session tool.

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 100% with enum values and bounds already documented, so the baseline is 3. The description demonstrates the 'pack' parameter with a concrete value ('onboarding') and mentions 'specific tool names' for the tools array, but adds no semantics about precedence or combination between the two parameters.

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 (enable) and resource (a HighLevel MCP tool pack or named tools) scoped to the 'current Progressive Discovery session'. An agent can tell it apart from read-oriented siblings like ghl_agency_tools_search, though the contrast is only implicit.

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 example invocation shows the intended shape of a call and the session scope is named, but there is no explicit when-to-use/when-not guidance and no reference to the sibling ghl_agency_tools_search (which one would presumably use to discover names before enabling them).

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