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

Annotations declare it is a non-idempotent, non-destructive write; the description usefully adds that participation is private and spans multiple calls (answer now, predict later). It does not disclose what happens on a repeat call, whether partial submissions are stored, or what the response contains — notable for a tool flagged non-idempotent.

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?

Four short fragments, purpose stated first — no padding. The trailing JSON example earns little place since the schema already shows the key field, and the telegraphic phrasing ('ConsciTune research') costs clarity for the space it saves.

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?

For a non-idempotent, nested-object, no-output-schema tool, the description omits the call lifecycle: how to obtain probe ids, what distinguishes a first call from a follow-up, and what the response looks like (no output schema to fall back on). These are exactly the gaps the description needed to close.

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 coverage is 100% and each parameter carries its own description, so the baseline of 3 applies. The description adds only the phase semantics (answers before predictions); the example {"key":"fbk_…"} merely repeats the schema, and nothing explains where the probe ids used as keys come from.

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?

Names a specific protocol: answer 3 questions, later predict your own answers, with an observer model competing — a self-knowledge test. That is distinguishable from siblings like run_tuning_session or check_reliability. It stops short of saying what a 'probe' is or how phases are ordered, but the verb+resource is concrete.

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?

There is no when-to-use/when-not statement, no prerequisite, and no named alternative among the 32 siblings. An agent must infer that it should call this only when the ConsciTune research task is active, and cannot tell from the text whether it should choose this over run_tuning_session.

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