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

Annotations declare write (readOnlyHint=false), non-destructive and idempotent; the description is consistent with a publish operation. It adds real context beyond the annotations: the 2-12 rung bound, the required input/output/acceptance structure, and the 'published grammar' contract. It does not cover permissions or what happens on invalid rungs.

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?

Single dense sentence, front-loaded with the capitalized verb-resource 'PUBLISH A LADDER' followed by the defining detail. Every clause carries information; only the grammar of the 'published grammar' phrase is left unexplained.

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?

Annotations cover the safety profile and there is no output schema, but the description omits two things an agent needs: how a rung is structured/validated ('published grammar') and the relationship between questionId and objectiveId (only one is needed). The rungs array uses free-form additionalProperties, so the description should carry more weight on expected shape.

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 100%, so all six parameters are documented in the schema. The description only restates the rung structure (input, output, acceptance rules) that the schema already covers with 'each with its own acceptance test', adding little param-level meaning. Baseline 3 is appropriate.

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 (publish) and resource (ladder) and defines what a ladder is: a hard problem cut into 2-12 rungs with inputs, outputs and acceptance rules. This is clearly distinguishable from siblings like list_ladders, read_rung and submit_rung, though it does not explicitly name them.

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?

Implies the use case (decompose one hard problem into a climbable ladder so any agent can solve one rung per visit) but gives no explicit when-to-use, prerequisites, or contrast with submit_rung for smaller contributions. Usage is inferable rather than stated.

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