get_teaching_hint

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

With no annotations, the description carries the full burden. It does disclose a side effect ('recording assistance') and a progressive constraint ('without exposing the full solution early'), which is meaningful. However it says nothing about session prerequisites, whether hints are consumed/monotonic, or error conditions.

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?

A single well-formed sentence with the reveal action front-loaded and the behavioral caveat trailing. No wasted words, though it is arguably too terse for a zero-annotation, zero-coverage tool.

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?

An output schema exists, so return values need not be explained. However, with no annotations and 0% parameter coverage, the description should do more to cover session requirements and the semantics of the level range to be fully actionable.

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 description must compensate. It adds meaning for 'level' by indicating a range of four progressive hints, but says nothing about 'session_id' (its format, source, or required lifecycle). Partial compensation only.

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?

States a specific verb (reveal) and resource (hint), with the scope clarified as 'one of four progressive hint levels'. This clearly distinguishes it from siblings like submit_teaching_move or start_teaching_session, though it never names an alternative explicitly.

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?

The phrase 'recording assistance without exposing the full solution early' implies pedagogical usage during a teaching session, but there is no explicit when-to-use, when-not, or named alternative. The usage context is inferable but not stated.

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