knitbrain_metrics

Retrieves compression telemetry including CCR tier counts and per-kind retrieval rates to enable TOIN self-tuning.

Instructions

Compression telemetry: CCR tier counts + per-kind retrieval rates (TOIN self-tuning).

Behavior2/5

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

No annotations are provided, so the description must disclose behavioral traits. It mentions 'TOIN self-tuning' but does not clarify if the tool is read-only, requires any permissions, or has side effects. This is insufficient for understanding the tool's behavior.

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?

The description is a single concise sentence that immediately conveys the tool's purpose without any waste.

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

Completeness4/5

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

Given no output schema, the description adequately states the return contents (CCR tier counts and per-kind retrieval rates). However, it lacks details on format or whether it is a summary, which would improve completeness.

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

Parameters4/5

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

The input schema has no parameters, meeting baseline. The description adds meaning by explaining what the tool returns, which is helpful beyond the empty schema.

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

Purpose4/5

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

The description specifies the tool provides 'Compression telemetry' with 'CCR tier counts + per-kind retrieval rates (TOIN self-tuning)'. This is clear and distinguishes it from sibling tools like knitbrain_classify_task or knitbrain_propose_agents, though no explicit verb is used.

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 the tool is used for monitoring or tuning compression telemetry, but provides no explicit guidance on when to use it versus alternatives or 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.
