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

Adds real context beyond annotations: the edit is immediate (no review gate) and restricted to human authors. However, annotations flag destructiveHint=true, and the description never says whether the new value fully replaces the existing field content (the 12000-char max suggests full overwrite) or what happens to prior text — the most important consequence for a destructive write.

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?

Two short sentences, the primary action is front-loaded, and the constraint sentence is the only other thing an agent needs. No waste.

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 should ideally say what a successful call returns or what happens on invalid field/value. For a destructive, non-open-world mutation with schema gaps, this leaves the agent slightly under-informed.

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 carry parameter meaning; it clarifies that exactly one field is targeted per call, but adds no detail on the value's semantics (replace vs. append), length limits, or the field enum. Baseline-level 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+resource: an immediate, human-authored edit to one Knowledge Profile field. It also implicitly separates itself from the proposal-review sibling path, though it never names that tool (e.g. devtune_review_knowledge_proposal), leaving a small inference step.

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?

Gives a clear when-to-use ('human-authored edit') and an explicit when-not ('System and agent changes must still use proposals'), which is the crucial routing rule given many sibling proposal/review tools. It would be a 5 if it named the alternative tool directly.

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