st.regex.configure

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

With no annotations provided, the description must carry behavioral disclosure. It does add the important confirmation requirement and the fact that the tool is global in scope, but it does not disclose deletion consequences, whether updates overwrite, default action behavior, or permission/persistence details.

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 brief and front-loaded, with two sentences and no filler. It efficiently conveys the main purpose and the critical confirmation requirement, though a bit more structure around parameter usage would improve clarity.

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?

This is a complex 15-parameter mutation tool with no annotations and no output schema, but the description covers only high-level actions and the confirm flag. It lacks essential context about parameter semantics, return values, defaults, and side effects, making it insufficient for an agent to invoke it correctly in nontrivial 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?

Schema description coverage is 0%, so the description must compensate for 15 parameters, but it only clarifies confirm: true and loosely describes the action categories. It does not explain findRegex, replaceString, placements, minDepth/maxDepth, runOnEdit, promptOnly, trimStrings, markdownOnly, substituteRegex, or snapshotLabel.

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 names a specific resource (global ST regex script) and a clear set of operations: create, update, enable/disable, delete. This distinguishes it from sibling tools like st.regex.registry and other configure tools without needing to inspect the schema.

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 this is the tool to use for managing global regex scripts and gives a hard prerequisite (confirm: true). However, it does not explicitly say when to prefer this over alternatives, mention st.regex.registry for listing, or explain what happens when certain parameters are omitted.

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