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

The description explicitly discloses replacement semantics, which is the key behavioral trait, and scopes the operation to the person's own note. Annotations are consistent with a write operation, and the destructive aspect of overwriting is surfaced by the word 'Replace'.

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?

One front-loaded sentence with no filler; the parenthetical adds useful examples without bloating. Every element earns its place.

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?

The definition covers the action, target, and content scope, but leaves open behavior when no note exists, return or success signaling, and any prerequisites or error conditions. With no output schema and non-informative annotations, these gaps keep it from being fully self-sufficient.

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?

With schema description coverage at 0%, the description carries the parameter meaning: 'note' maps to notes, and 'tracked application' maps to application_id. The parenthetical examples clarify the expected note content, though application_id's source or format is not detailed.

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?

The description states a specific verb ('Replace'), a clear resource ('the person's own note on one tracked application'), and gives examples of note content. This distinguishes it from tracker siblings like get_tracker and move_tracker_card.

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 description implies the write-on-tracker use case but never explicitly says when to choose it over alternatives or when not to use it. There are no exclusions or conditional guidance, so an agent must infer fit from the action name and context.

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