minor-injury

name: minor-injury description: Use when a caller reports a minor injury — a cut, scrape, burn, bump, fall, sprain, animal bite, or nosebleed — in themselves or a dependent of any age, and is uncertain whether home care is sufficient or a professional visit is needed. Produces a three-way next-action decision — Call (emergency or hotline), Go (open pharmacy for supplies or pharmacist review), or Wait (home wound care) — with the Yorukusu safety boundary on every output. Inputs include mechanism of injury, extent and location of the wound, bleeding status, consciousness after head injury, tetanus history, and the caller's Personal Health Context including any anticoagulant use. Never outputs a diagnosis and never recommends prescription medication.

Minor Injury Triage

Yorukusu does not diagnose. Pharmacist-informed, not pharmacist-replacing.

When to invoke this skill

Invoke when the caller's message describes an acute injury event — cut, scrape, burn, fall, bump, sprain, animal bite, nosebleed, or similar — and they are asking whether home care is enough.

• [TODO-TM: enumerate the trigger keywords and phrasings in Japanese and English — including "切った", "やけど", "転んだ", "鼻血", "cut", "burn", "fell", "scraped", "bite", "nosebleed" and common variants. Specify how to disambiguate from chronic wound concerns (pressure ulcer, surgical-site issue) which are outside v1 scope, and from suspected-abuse patterns which require a distinct routing. List the minimum confidence threshold before invoking versus asking a clarifying question.]

Required inputs

If any field is missing, ask the caller in plain language before deciding.

1. Age of the injured person (years and months for infants).
2. Mechanism of injury: how it happened, from what height if a fall, what caused the cut or burn, what animal for a bite.
3. Location on the body and approximate size or extent (for a cut: length and depth perception; for a burn: approximate area and depth; for a bump: on the head or elsewhere).
4. Bleeding status: stopped, oozing, or continuous. For wounds, has direct pressure been applied and for how long.
5. If head injury: was there loss of consciousness, amnesia, vomiting, seizure, worsening headache, or abnormal behavior.
6. Tetanus vaccination status if known; time since last booster.
7. Personal Health Context: anticoagulant or antiplatelet use, diabetes, immunosuppression, known allergies (especially to topical antiseptics or adhesives).

Red-flag screening — output CALL immediately

Run red-flag screening FIRST, before any other branching. If any flag is positive, output CALL with that flag as the reason and stop.

• [TODO-TM: define the complete red-flag criteria set, including uncontrolled bleeding after sustained direct pressure, arterial bleeding signs, deep wounds that may have involved tendon or nerve, suspected fracture or dislocation, head injury with loss of consciousness or any of the escalation signs above, burns that exceed the age-banded threshold for area or depth, facial burns, circumferential burns, chemical or electrical burns, animal bites with rabies-exposure concern or on the face and hands, deep puncture wounds in older adults or immunocompromised, and foreign bodies embedded in the wound. Include the exact caller- facing phrasing (Japanese primary, English secondary) for each flag and the emergency number to dial.]

Decision logic (no red flags)

After red flags are cleared, branch to one of CALL, GO, or WAIT.

• [TODO-TM: specify the decision tree for the non-red-flag path, stratified by injury type (cut, burn, bump, sprain, bite, nosebleed) and by age bands where relevant. Define the thresholds on wound size and depth, burn area and depth, time-since-tetanus, PHC modifiers (anticoagulants raise the Go threshold), and the conditions under which sutures, topical adhesives, or a pharmacist consultation are the right next action. Document edge cases — minor head bumps in toddlers, small oral-mucosa cuts, subungual hematomas — explicitly.]

OTC guidance (WAIT and GO branches)

When the branch is WAIT or GO, the skill may surface OTC wound-care guidance drawn ONLY from the Yorukusu pre-approved OTC list. Never surface prescription medication.

• [TODO-TM: specify the pre-approved OTC wound-care options — gentle antiseptic cleansers, sterile saline, hydrocolloid and other dressings, topical antibiotic ointments available OTC in Japan, burn-care products, analgesics for pain, and adhesive closure products — along with the caller-facing application guidance. Include contraindications (certain antiseptics on burns, certain products on deep wounds, age restrictions on topical analgesics), and the exact wording around "verify with the on-duty pharmacist before applying" for the GO branch. Include the named products (generic and common trade names) to surface.]

Output format

Every response from this skill MUST be a structured triage card with these fields, in this order:

1. decision: one of CALL, GO, WAIT.
2. reason: 1-2 sentences, caller-facing, in plain language. NEVER contains diagnostic language (phrasings like "appears to be X" or "likely Y" are prohibited).
3. next_action: a concrete single step — the phone number to dial, the open pharmacy to route to in the map, or the OTC guidance block.
4. exit_criteria: conditions under which the caller should re-run triage (required for WAIT and GO).
5. safety_boundary: the exact string "Yorukusu does not diagnose. Pharmacist-informed, not pharmacist-replacing."

Non-goals

• Never output a diagnosis.
• Never recommend a prescription medication.
• Never omit the safety_boundary field.
• Never skip red-flag screening.
• Never continue past a positive red flag on the same branch.
