Add to Daily Note

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

With no annotations, the description carries the full behavioral burden; it does disclose that each call appends rather than overwrites and that markdown is supported, which is useful. It does not say whether a daily note is created when none exists for today, where in the note content lands relative to the timestamp, or that the markdown syntax can create Task/Tag objects as a side effect (that only appears in the schema).

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?

Three short sentences with the core action front-loaded and no filler. Every sentence contributes: target, format support, and append semantics.

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 two-parameter append tool with a fully documented schema and no output schema, the description covers the essentials. The main residual gap is note-creation behavior when today's note does not yet exist, which an agent would want to know before calling.

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%, so the schema already explains markdown conventions and the no_timestamp flag in detail. The description only echoes that markdown is supported and says nothing about no_timestamp, so it adds little beyond the structured field data — baseline 3 is appropriate.

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 gives a specific verb and resource ("Add content to today's daily note in Capacities") plus the scope constraint that only today's note is targeted, which separates it from the generic append_to_object sibling. It stops short of naming that sibling or any other alternative, but the action itself is unambiguous.

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?

Usage is only implied: an agent can infer this is for journaling into today's note rather than an arbitrary object, but the description never states when to prefer it over append_to_object, create_object, or update_object. No exclusions or prerequisites are given.

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