pennylane_create_journal

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

Annotations already declare readOnlyHint=false, idempotentHint=false, destructiveHint=false and openWorldHint=true, so the write/idempotency profile is covered. The description adds no behavioral context beyond that — no mention of duplicate-code errors, required permissions, or whether journals are scoped to the active dossier.

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?

Two short sentences, purpose front-loaded, no filler. The code list is somewhat redundant with the schema's code parameter description, which keeps it from being fully economical.

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 creation tool with an output schema and full annotation coverage, the definition provides enough to call it: purpose, required code/label, and conventional code values. Only multi-dossier scoping and duplicate handling are left unstated.

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 baseline is 3 for params the schema already documents. The description largely repeats the schema's own examples (VE, HA, BQ, OD) and only marginally extends them with PA (paie) and RB (reprise de balance), so real added value is small.

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 ('Crée un nouveau journal comptable'), so the agent immediately knows this creates a chart-of-accounts journal. It does not name the sibling reads (pennylane_list_journals / pennylane_get_journal), but the verb choice makes the distinction self-evident.

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 is given: nothing about prerequisites (fiscal year/dossier context), when a new journal is warranted versus reusing an existing one, or what to do if the code already exists. The second sentence is about parameter values, not usage conditions.

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