ck_tool_health

Read-onlyIdempotent

Analyzes governance coverage across recent sessions, categorizing each governance tool as load-bearing, active, low-usage, or unused. Returns actionable recommendations for gaps.

Instructions

Analyze governance coverage across recent sessions in the workspace — which CK governance tools (ck_validate, ck_review_submit, ck_budget, ck_memory_record, ck_goal) are load-bearing, active, low-usage, or unused — and return actionable recommendations for gaps.

project_rootNoAbsolute path to the project root directory on the local filesystem.
session_idNoUnique session identifier for correlating findings, proofs, budget, and audit trail.
session_limitNoNumber of recent sessions to analyze. Defaults to 10.

Behavior4/5

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

Annotations already provide readOnly, destructive, and idempotent hints. The description adds that the tool returns actionable recommendations, which is valuable behavioral context beyond what annotations provide.

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

Conciseness4/5

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

The description is a single sentence that conveys the purpose and output clearly, though it is somewhat lengthy. It is front-loaded with the main action.

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 presence of an output schema and comprehensive annotations, the description fully explains the tool's purpose and return value, leaving no significant gaps.

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% and all parameters are described in the schema. The description does not add additional meaning beyond the schema, so baseline score of 3 is appropriate.

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 verb 'analyze' and the resource 'governance coverage across recent sessions', and distinguishes itself from siblings by focusing on meta-analysis of specific CK governance tools.

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

Usage Guidelines3/5

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

The description implies use for analyzing governance tool usage but does not explicitly state when to use this tool versus alternatives or provide exclusion criteria.

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