timps_update_manager

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

With no annotations, the description carries the transparency burden. It discloses that the tool returns a prioritized update plan (security-first) and a safe ordered shell script, signaling that it is a check-and-report tool rather than an automatic mutation. It doesn't detail operational prerequisites like network/permissions, but enough behavior is conveyed.

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 compact, well-structured, and includes all necessary high-level details in two sentences: input scope, output type, prioritization scheme, and key characteristic of the script. There is no wordiness or filler.

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 this is a zero-input tool with no annotations and no output schema, the description fully covers the relevant context: what systems/packages are scanned, what the output is, and how it is ordered. Enough for an agent to know when and how to invoke 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?

The tool takes zero parameters, so there is no parameter semantic gap to fill. The baseline score of 4 applies because the description doesn't need to explain input fields; the schema and context already confirm the absence of inputs.

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 what the tool does: checks for pending updates across specific categories (macOS/Linux OS, Homebrew, npm, pip). It uses a definitive verb ('Check for pending updates') and enumerates the exact resources, distinguishing it from broader or generic update tools in the sibling list.

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 usage context is only implied: use this when you want to see pending updates and obtain an ordered script. It does not explicitly state when to prefer this tool over related sibling tools like timps_dependency_rebel or timps_system_optimizer, nor does it mention when not to use it.

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