calculate_blood_alcohol

Estimate blood alcohol content (BAC) using the Widmark formula. Get BAC percentage, French legal status, and estimated time to become sober. Input number of drinks, weight, sex, and hours drinking.

Instructions

Estimate blood alcohol content (BAC) using Widmark formula. Returns: {bac_percent, legal_status_fr, estimated_sober_in_hours}. See list_bundles for related 'sante' calculators.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
drinksYesNumber of standard drinks (1 drink = 14g pure alcohol)
weight_kgYesBody weight in kilograms
sexYesBiological sex
hours_drinkingYesHours elapsed since first drink

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
resultNoComputed result. Object whose fields depend on the tool (e.g. {tax, marginal_rate, brackets} for tax tools, {volume_l, gallons} for volume tools).
formulaNoHuman-readable formula or method used (e.g. "I=P·r·t", "Magnus formula").
sourceNoAuthoritative source for the rule or formula (e.g. "Article 197 CGI", "NF DTU 21").
reference_urlNoLink to a calcul2 page documenting the calculation in detail.
Behavior2/5

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

No annotations provided; description merely states formula and return structure but omits assumptions, accuracy, or limitations. Does not disclose behavioral traits beyond the obvious.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two succinct sentences: first states purpose, second mentions return and sibling tools. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a calculation tool: lists return fields. But lacks details on formula assumptions or accuracy bounds. Output schema exists but description is sufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 100% coverage with descriptions. Description adds no parameter-level details beyond listing return fields; it does not enrich parameter understanding.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states estimate blood alcohol content using Widmark formula, specifies return fields, and is distinct from sibling tools like calculate_alcohol_units.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool vs alternatives. Only a vague reference to list_bundles for related calculators, but no direct comparison or exclusion.

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