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

With no annotations, the description carries the transparency burden and does disclose substantive behaviors: pulling, verifying local package resolution, and baseline-compiling roots. However, it does not mention potential side effects of the pull/compile, permissions needed, or what happens on failure, leaving notable gaps.

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 focused sentence that front-loads the main action and then lists the required safety-gate steps. Every clause adds useful information, and there is no filler or redundant repetition of the tool name.

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?

The tool is relatively low-complexity with one parameter and an output schema, so the description covers the high-level workflow well. However, it lacks parameter semantics and side-effect disclosure, and with no annotations the description must bear more weight than it currently does.

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 parameter, 'name', with a default of empty string and 0% schema description coverage. The tool description never explains what 'name' should contain (project identifier? path?), how it is used, or whether it is truly optional. This is a significant omission for a single-parameter tool.

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 identifies the action as opening a project and running a safety gate with specific steps: pull, verify \usepackage resolution, and baseline-compile each root. This distinguishes it from sibling read/write/compile tools, especially by positioning it as a prerequisite before any write.

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 explicitly states 'Required before any write,' giving a clear condition for when to use this tool rather than directly using write/edit siblings. It does not enumerate exclusions or alternative tools, but the required-before-write context is strong guidance.

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