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

Goes well past the annotations (readOnlyHint=false, destructiveHint=false, idempotentHint=false) by disclosing data-handling behavior: the note is encrypted, visible to EasyShiftPlan administrators for up to 180 days, and not linked to a store or demo. It also enumerates prohibited content and states the write is optional with no effect on schedules - exactly the context a mutation tool needs.

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?

Front-loads the core action and pushes prerequisites immediately after, then closes with privacy and content constraints. It is dense but each clause (opt-out, retention, PII prohibitions, optionality) carries distinct information, with only mild overlap between the sentence-level prohibitions.

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 described, and everything else an agent needs is present: prerequisites, opt-out handling, retention/visibility, content prohibitions, and optionality. Nothing material is missing for a 1-required-param tool.

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% and both optional params carry enums with defaults, so the schema already documents them. The description reinforces the message constraint ('do not include prompts, names, contact details...') but adds no per-parameter syntax or format detail. Baseline 3 applies.

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 ('Store one brief, assistant-authored observation about product behavior') and immediately bounds the scope to 'at any stage', which separates it from the demo-gated siblings like run_public_demo and the read-side get_demo_feedback_reply. An agent can select it without opening any schema.

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 clear trigger conditions: usable at any stage, with no prior demo, login, account, demo ID, or feedback reference needed, and it must honor an explicit opt-out. It never names a sibling as the alternative for a different case, so routing guidance stops just short of the top band.

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