memory_scope_enable

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It discloses that the tool re-enables a scope and that the effect is session-scoped, which is useful context. However, it does not mention edge cases such as attempting to re-enable an already-enabled scope, invalid scope identifiers, or whether the action is reversible. The description offers the basic behavior but lacks depth.

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 a single, front-loaded sentence: 'Re-enable a previously disabled scope for this session.' It is concise, contains no filler, and communicates the essential purpose immediately. Every word contributes to the meaning.

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 tool with one required parameter, no annotations, and an output schema (not shown), the description is minimally adequate. It clarifies the core operation and session scoping, but it does not explain what a 'scope' is, how to reference it, or what error conditions may arise. The presence of an output schema mitigates the need to describe return values, but there is still ambiguity around scope semantics and edge cases.

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?

The schema has one required parameter 'scope' with no description (0% coverage). The description implies that the parameter is the identifier of the previously disabled scope, giving it some meaning. However, it does not specify the expected format (e.g., name vs. ID), whether there are constraints, or how the scope value relates to other memory tools. It adds minimal semantic value beyond the schema.

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 clearly states the action: 'Re-enable a previously disabled scope for this session.' It specifies a precise verb (re-enable), the resource (scope), and contextual constraints (previously disabled, session-scoped). This distinguishes it from its sibling tool memory_scope_disable, which performs the inverse operation.

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 description implies usage after a scope has been disabled (it references 'previously disabled scope'), but it does not explicitly state when to use this tool versus alternatives, nor does it name the inverse sibling (memory_scope_disable). There is no guidance on prerequisites or conditions when not to use it. The context is implied but not fully elaborated.

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