Openfda Drug Profile

openfda_drug_profile

Read-only

Resolve one drug name to its FDA identity, then fan out in parallel across the bounded per-drug openFDA endpoints and merge into one profile: identity, label highlights, adverse-event summary, recall history, Drugs@FDA approval, and shortage status. Replaces chaining openfda_get_drug_label, openfda_search_adverse_events, openfda_search_recalls, openfda_search_drug_approvals, and openfda_search_drug_shortages — and reconciles the identifier drift between endpoints that makes that chaining error-prone. Each section is best-effort: a miss returns null rather than failing the call. For deep dives into any one area, use the dedicated tool.

Input Schema

Name	Required	Description	Default
`drug`	Yes	Drug name to profile — brand or generic (e.g. "metformin", "Humira", "Glucophage"). Resolved once to an FDA identity; meta.fanOutKey reports the name the recall, approval, and shortage sub-queries searched.

Output Schema

Name	Required	Description
`meta`	No	Request metadata.
`error`	No	Present when the call failed. Absent on success.
`label`	No	Label highlights from drug/label, or null when no label matched.
`notice`	No	Guidance when the drug could not be resolved or upstream errors degraded the profile. Absent on a fully populated profile.
`recalls`	No	The newest 5 drug/enforcement recall actions whose openfda.generic_name or product_description matches meta.fanOutKey (may be empty); recalls_total counts every match.
`approval`	No	Best-matching Drugs@FDA application whose openfda.generic_name or products.active_ingredients.name matches meta.fanOutKey, or null when none matched or the sub-query failed (listed in degraded).
`degraded`	No	Sub-queries that failed upstream, empty when every section resolved. A section listed here is unknown, not absent — a null section with no entry here genuinely has no FDA record.
`identity`	No	Identity resolved once and reused across every sub-query to avoid identifier drift.
`shortage`	No	Current or most-recent drug shortage status, or null when none on record.
`recalls_total`	No	Total drug/enforcement reports the recall search matched — recalls lists the newest 5 of them. Null when the recall sub-query failed (listed in degraded): unknown, not zero.
`sectionsFound`	No	How many profile sections (label, adverse_events, recalls, approval, shortage) returned data.
`adverse_events`	No	Adverse-event summary aggregated over drug/event, or null when unavailable.

TDQS

A4.6/5.0

Behavior5/5

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

Annotations only declare readOnlyHint=true; the description adds substantial behavior: parallel fan-out across bounded per-drug endpoints, per-section best-effort semantics where a miss returns null instead of failing the call, identifier-drift reconciliation between endpoints, and the meta.fanOutKey reporting mechanism. These are exactly the failure-mode details an agent needs to interpret partial results.

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

Conciseness4/5

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

Front-loaded with the core action and output shape, then the sibling substitution, then the caveats. Every sentence carries information, though the 'Replaces chaining...' sentence is long and could be split for scannability.

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

Completeness5/5

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

For a single-parameter aggregation tool with an output schema (so return shape needn't be described), the description covers the aggregation scope, partial-failure behavior, and the escape hatch to single-purpose tools. Nothing needed to invoke it correctly is missing.

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?

Only one parameter and schema coverage is 100%, with the schema already explaining brand/generic acceptance and meta.fanOutKey. The description restates the single-resolution-then-fan-out behavior but adds no format, normalization, or disambiguation guidance beyond what the schema field says, so the baseline 3 is appropriate.

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?

States a specific verb and resource ('Resolve one drug name to its FDA identity') and then enumerates exactly what the merged profile contains: identity, label highlights, adverse events, recalls, approvals, shortages. It distinguishes itself from siblings by naming the five single-purpose tools it replaces, so an agent can route without opening any schema.

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

Usage Guidelines5/5

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

Explicitly frames this as a replacement for chaining openfda_get_drug_label, openfda_search_adverse_events, openfda_search_recalls, openfda_search_drug_approvals, and openfda_search_drug_shortages, and states the inverse case: 'For deep dives into any one area, use the dedicated tool.' Both the when and the when-not are present with named alternatives.

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