ofw_create_journal_entry

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

Annotations already declare readOnlyHint=false, destructiveHint=true, and openWorldHint=true, so the safety profile is covered. The description adds nothing beyond that: no note on visibility/audience of the entry, no confirmation that it is an additive write despite the destructiveHint flag, and no auth or side-effect context.

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?

A single front-loaded sentence with zero filler. It is efficient, though the brevity borders on under-specification for a mutation tool rather than being a model of tightness.

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 write tool with no output schema, the description should say what happens on success, whether the entry is published immediately, and any permission requirements. It supplies none of that, leaving the agent with only the tool name and the schema.

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?

Both parameters (title, body) have 100% schema description coverage, so the schema carries the semantics. The description does not add format, length, or content constraints 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?

States a specific verb and resource ('Create a new journal entry') plus the product context (OurFamilyWizard), so the action is unambiguous. It stops short of differentiating from the sibling ofw_list_journal_entries or clarifying whether entries are private, shared, or family-scoped.

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?

No when-to-use guidance, no prerequisites, and no mention of alternatives such as ofw_list_journal_entries or ofw_save_draft. The agent must infer entirely from the name when this tool is appropriate.

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