# Food Safety Temperature Log Analyzer

## Purpose
Turn raw temperature log data into a violation-flagged compliance report — identifying every out-of-range reading, ranking each by food-safety severity, prescribing the exact corrective action, and summarizing overall compliance status so managers catch problems before an inspector does.

## When to Use
Invoke this skill when the user asks to:
- Review temperature logs for coolers, freezers, walk-ins, or hot-holding units
- Flag out-of-range or missing temperature readings in a log
- Diagnose why a unit keeps failing temperature checks
- Prepare a temperature compliance summary before a health inspection
- Verify cooling or cooking steps met HACCP time/temperature requirements
- Build a corrective action list from a week or month of logs

## Inputs Required
Before starting, collect:
- **Log data**: The readings — as a table, list, or pasted export (include timestamps and unit/location labels if available)
- **Equipment/step type**: Cold-holding, freezer, hot-holding, cooking, cooling, or reheating (one or a mix)
- **Applicable code standard**: FDA Food Code, local health department, or organization SOP (default: FDA Food Code)
- **Reading frequency expected**: How often logs should be recorded (e.g., every 2 hours, per shift)
- **Time period covered**: Date range of the logs
- **Product context** (optional): What food is stored/prepared in each unit, if known

If no code standard is specified, apply the FDA Food Code thresholds below and note the assumption.

## Instructions

### Step 1: Apply the Correct Temperature Thresholds
Match each reading to its standard (FDA Food Code defaults):
- **Cold-holding**: 41°F (5°C) or below. Anything 42°F+ is out of range.
- **Freezer**: 0°F (-18°C) or below recommended; product must remain frozen solid.
- **Hot-holding**: 135°F (57°C) or above. Anything 134°F or below is out of range.
- **Cooking (final internal temps)**: Poultry 165°F; ground meat 155°F; whole cuts/fish 145°F; eggs to order 145°F. Flag any reading below the required minimum for that product.
- **Cooling**: 135°F → 70°F within 2 hours, then 70°F → 41°F within an additional 4 hours (6 hours total). Flag any cooling record that breaches either window.
- **Reheating**: 165°F within 2 hours.
- **Danger zone**: 41°F–135°F. Time spent here is cumulative and matters for cooling/cold-holding failures.

### Step 2: Flag Every Reading
Classify each log entry:
- **In range** — meets threshold
- **Out of range** — breaches threshold (report actual vs. required)
- **Missing** — a scheduled reading has no entry (a documentation violation even if temps were fine)
- **Suspect** — physically implausible or duplicated values suggesting the log was backfilled rather than measured live

### Step 3: Assign Severity to Each Violation
- **Critical**: Reading in the danger zone with likely time-temperature abuse (e.g., cold-holding at 50°F, or cooling that missed the 2-hour mark). Product safety compromised — likely discard.
- **Major**: Out of range but marginal or short-duration, or a repeated pattern on one unit signaling equipment failure.
- **Minor**: Missing or late entries, or readings 1–2°F over threshold on a single occasion.

### Step 4: Prescribe Corrective Actions
For each flagged reading or pattern, give a specific action — not "monitor more closely":
- Cold-holding breach → check product temp with calibrated thermometer; discard TCS food held above 41°F beyond 4 cumulative hours; service the unit if internal temp is failing.
- Hot-holding breach → reheat to 165°F within 2 hours or discard; verify unit is set correctly.
- Cooling failure → discard product that missed a window; retrain on ice-bath/shallow-pan methods; log corrective in the temperature record.
- Recurring unit failure → escalate to equipment repair; move product to a working unit; increase check frequency until resolved.
- Missing/late entries → identify accountable shift; retrain on logging cadence; consider a reminder system.

### Step 5: Identify Patterns
Look across the full period for:
- A single unit failing repeatedly (equipment problem, not human error)
- Failures clustered at specific times (shift change, delivery, defrost cycle)
- Systematic missing entries on certain shifts or days
- Signs of backfilled logs (identical values, round numbers, timestamps out of sequence)

### Step 6: Summarize Compliance Status
Produce an overall status: **Compliant / Compliant with Corrections Needed / Non-Compliant**, with the counts and the top risks driving the rating.

## Output Format
- **Structure**: Compliance summary header → violation table → severity-ranked corrective actions → pattern findings → inspection-readiness note
- **Length**: 500–900 words depending on log volume
- **Format**: A violation table (reading, unit, timestamp, actual vs. required, status, severity), plus prose sections for patterns and summary
- **Sections**: Overall Compliance Status → Flagged Readings Table → Corrective Actions (ranked Critical → Major → Minor) → Patterns & Root Causes → Inspection Readiness
- **Tone**: Compliance officer — precise, non-alarmist, action-first; cites the specific threshold each violation breached

## Quality Checklist
Before delivering output, verify:
- [ ] Every reading is classified (in range / out of range / missing / suspect) — none skipped
- [ ] Each out-of-range reading shows actual value vs. required threshold
- [ ] Every violation has an assigned severity (Critical / Major / Minor)
- [ ] Each corrective action is specific and executable — no "monitor more closely"
- [ ] Missing/skipped scheduled readings are flagged as violations, not ignored
- [ ] The report ends with a single clear compliance status and the count of critical violations

## Notes
- Missing documentation is itself a violation — an inspector treats a blank log the same as a failed reading.
- Cooling failures are the most commonly missed on manual review because they require checking two time windows, not one temperature — always verify both the 2-hour and 4-hour marks.
- If timestamps are absent, note that time-based standards (cooling, danger-zone duration) cannot be fully verified, and recommend adding timestamps to future logs.
- Recurring failures on one unit are almost always equipment, not staff — recommend a service check before retraining.
