_delimit_context_impl

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

With no annotations provided, the description should disclose behavioral traits. It lists actions but lacks details on side effects, destructiveness, authentication needs, or state management. For a tool that likely modifies a filesystem, this is insufficient.

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 very concise, with a single sentence and action list. It is front-loaded but could benefit from more structure (e.g., grouping parameters by action). However, it avoids unnecessary text.

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?

Given the tool's complexity (8 parameters, multiple actions) and lack of annotations, the description is too minimal. It does not explain return values (though output schema exists), parameter dependencies, or action-specific constraints, leaving significant gaps for an agent.

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%, so each parameter is documented in the schema. The description adds no extra meaning beyond listing actions. Baseline of 3 is appropriate.

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 tool manages a context filesystem for cross-model continuity and lists specific actions (init, read, write, list, snapshot, branch). This conveys the core purpose. However, it does not differentiate this tool from sibling tools like delimit_context_init, delimit_context_read, etc., which seem to provide individual actions.

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?

No guidance is provided on when to use this multi-action tool versus the dedicated sibling tools. The description does not specify scenarios where this implementation tool is preferred over the individual context tools, leaving the agent without clear direction.

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