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

Annotations already mark this as a non-read-only, non-idempotent, non-destructive operation, so the safety profile is covered. The description adds the ≥10-answer threshold and explains what the returned report contains, but it does not state what happens if called twice, whether the session is consumed, or what occurs below the answer threshold. Some useful behavioral context, but not rich side-effect disclosure.

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 purpose and outputs are front-loaded, followed by the prerequisite and the recommended next actions. The paragraph is dense with useful details and has little waste, though it is somewhat run-on with multiple clauses packed into one block.

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?

There is no output schema, so the description must explain return values, and it does: overall level, competency breakdown, growth areas, report link, and the deep-dive variant. It also covers the answer-count prerequisite and follow-up recommendations. Minor gaps remain around session_id sourcing and error/edge behavior.

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 schema provides no explanation of session_id. The sentence about deep-dive sessions adds meaning by saying the session type changes the report shape (subcompetency profile), but it still does not explain where session_id comes from or its expected format.

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 states a specific verb and resource: finish the diagnostic and return a report, with concrete outputs (overall level, 10 competency levels, growth areas, full-report link, 90-day plan). It distinguishes the deep-dive session variant but never mentions the existing ruforge_get_report sibling, so the boundary versus a plain report-fetch tool is only implicit.

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?

It gives a clear prerequisite (at least 10 answers, preferably all) and explicitly recommends follow-up actions with named alternatives: ruforge_deep_dive_start for growth areas and ruforge_profile_request_code to save results. It does not explicitly say when not to call it versus ruforge_get_report, but the practical usage context is strong.

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