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

Beyond the annotations (readOnlyHint=false, destructiveHint=false, openWorldHint=true), the description discloses that visibility defaults to internal, that sharing reaches other people, that confirmation happens by default and can be toggled off, and that a Cotlet API key with app access is required. These are meaningful behavioral traits for a write tool with external reach.

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?

The description restates the same points multiple times: internal-by-default is stated three ways and the confirmation requirement twice ('By default you confirm each call' and 'confirm with the user before each call'). It is padded rather than front-loaded, and a fair chunk of text does not earn 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?

For a creation tool with no output schema, the description covers the key concerns: visibility default, sharing implications, confirmation expectations, and auth requirements. Nothing critical for calling it correctly appears to be missing.

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 coverage is 100%, so the schema already documents all five parameters including the share_with options and defaults. The description's mention of sharing reinforces share_with but adds no syntax or format detail beyond the schema, so the 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?

The description states a specific verb and resource ('Creates a daily log on one job under your name') and clarifies scope and ownership. It is clearly distinguishable from the sibling list_daily_logs, though it never names an alternative by name.

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?

It gives useful operational context (internal by default, share to reach subs/client, confirm before each call) but never states when to prefer this over siblings or when creation is inappropriate. Usage is implied rather than contrasted with alternatives.

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