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

No annotations are provided, so the description carries the full disclosure burden for a mutation tool, yet it says nothing about permissions required, whether disabling a cell affects the hierarchy, whether unlisted parameters are preserved, or whether changes are reversible. The cryptic '[PRIVATE MODIFY]' tag hints at restricted access but never explains it.

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?

It is a single short sentence with the operation front-loaded, but the bracketed '[PRIVATE MODIFY]' marker consumes space without conveying usable meaning, and the remainder is so terse it reads as under-specification rather than economy.

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 3-parameter mutation tool with no annotations and no output schema, the description omits side effects, permission model, return behavior, and the meaning of the private marker – well short of what an agent needs to invoke it safely.

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% and includes a documented range for riskWeight (0.0-1.0), so the schema already does the heavy lifting. The description only gestures at 'core Cell parameters or system thresholds' without adding mapping, units, or defaults 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 verb (Modify) and resource (Cell parameters / system thresholds) are present, but 'core Cell parameters' is vague and only becomes concrete via the schema (enabled, riskWeight). Nothing distinguishes it from siblings such as create_cell or run_brain_cell, and the '[PRIVATE MODIFY]' prefix is unexplained.

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?

There is no statement of when to use this versus create_cell or other cell tools, no prerequisites, and no indication of what '[PRIVATE MODIFY]' implies about access. The agent must infer usage entirely.

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