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

Annotations already declare readOnly, idempotent, non-destructive and openWorld, so the safety profile is covered. The description adds that returned solution content keeps original creator attribution, which is real context not in the schema, but it says nothing about the paged history behavior implied by history_limit/history_cursor.

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 front-loaded sentence that identifies the action and its output before the caveat. The trailing 'retaining original creator attribution; this is not a new search' is a bit dense but every clause carries meaning.

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 3-parameter read tool with no output schema, the description is roughly adequate but leaves the history pagination model (what history_limit limits, how the cursor is used) entirely to the schema. It does clarify return content, which is the main thing an agent cannot get elsewhere.

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 only 33%: history_cursor is documented in the schema while problem_id and history_limit have no descriptions at all. The description names no parameters and gives no format or semantics for problem_id or the history window, so it fails to compensate for the coverage gap.

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 and resource (read the existing problem) and adds what comes back ('complete available solution content'), which distinguishes it from a pure metadata peek like describe_problem. It does not name its siblings, so the agent must infer the split with read_solution_skill and describe_problem.

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 clause 'this is not a new search' gives one implicit exclusion, telling the agent this is a retrieval-by-id operation rather than discovery. No condition says when to prefer read_solution_skill or describe_problem, and no prerequisites are stated, so the guidance is implied rather than explicit.

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