Open Kioku Recommend Validation Plan

recommend_validation_plan
Read-onlyIdempotent

Generate a comprehensive validation plan—test targets, coverage checks, static checks—for a changed file, so you can choose the right tests and checks before finalizing.

Instructions

Recommend a comprehensive validation plan (test targets, coverage checks, static checks) for a file change. Use before finalizing a change to choose tests, static checks, and coverage actions for one path. Prefer find_tests_for_change for test-only recommendations. This is read-only.

Input Schema

pathYesThe repository-relative file path.
limitNoMaximum recommendations to return. Defaults to 20.

Output Schema

TDQS

A4.5/5.0
Behavior4/5

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

Annotations already declare the tool read-only, idempotent, and non-destructive. The description adds 'This is read-only,' which is consistent. It does not introduce contradictions, but adds little beyond annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three concise sentences: purpose, usage context with alternative, and read-only note. No fluff, each sentence is valuable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the output schema exists (not shown but present), the description adequately covers what the tool does, what inputs it needs, and when to use it. It references a sibling for more specific cases.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3. The description mentions 'for one path' tying to the required 'path' parameter but does not add details about 'limit' beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool recommends a validation plan for a file change, specifying verb 'recommend' and resource 'validation plan'. It distinguishes from sibling 'find_tests_for_change' by noting that tool is for test-only recommendations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit usage context: 'Use before finalizing a change to choose tests, static checks, and coverage actions for one path.' Also gives an alternative: 'Prefer find_tests_for_change for test-only recommendations.'

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