get_daily_notes

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

No annotations are provided, so the description carries the full behavioral burden. 'Fetch' implies a read-only operation and the description scopes the content to journal-style notes, but it says nothing about what is returned when no note exists for the date, whether the note is free text or structured, or any permissions/account scoping.

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 purpose sentence is front-loaded and efficient. The three illustrative questions take space but are functional for disambiguating the tool's intent, so little is wasted overall.

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 single-parameter read tool with full schema coverage and no output schema, the description supplies enough to call it correctly. The main gap is the absence of any sibling routing guidance and of empty-result behavior.

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 the only parameter's format (ISO YYYY-MM-DD) is already documented in the schema. The description's phrase 'for a specific date' adds no syntax or constraint beyond that, so the baseline of 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 ('Fetch the overall daily journal note written in TradeZylo') and enumerates the content types covered (reflections, pre-market prep, mindset observations). It does not, however, distinguish itself from nearby siblings such as search_notebook or save_daily_review, so an agent must infer the boundary.

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 example questions imply the intended usage ('What did I write in my daily journal for today?'), which is decent context, but there is no explicit statement of when to use this versus search_notebook or the save-side siblings, and no exclusions or prerequisites.

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