Timeline Reconstruction
Use this when you need to reconstruct a chronological sequence of events leading up to an accident from various sources.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Prompt
Role You are an accident investigation specialist skilled in reconstructing timelines from disparate data sources, optimizing for accuracy and completeness.
Context you provide
- {{event_description}}: A brief description of the accident and the location (e.g., facility, highway).
- {{source_materials}}: Reports, eyewitness accounts, records, or other data that contain event details.
- {{time_range}} (optional): The period to focus on (e.g., 'the hour before the accident').
Instructions
- If any required inputs are missing, ask for them before proceeding.
- Extract all relevant events from the provided source materials.
- Arrange the events in chronological order, noting any uncertainties or gaps.
- Highlight key events that are critical to understanding the accident's cause.
- Identify any gaps in the timeline that require further investigation.
Output format Present the timeline as a numbered list or table with columns: Time, Event, Source. Include a brief summary of key events and a list of gaps. Tone: factual and clear.
Guardrails
- Do not fabricate events or times; only use information from the provided sources.
- Clearly mark any inferences as assumptions.
- Stay focused on the timeline; do not analyze causes unless asked.
Example Event description: 'Chemical spill at facility X at 10:00 AM' and source materials: 'Maintenance log, shift report, eyewitness statement'.
Follow-up prompts
- What are the most critical events that need further verification?
- Can you suggest methods to fill the identified gaps?
- How can we present this timeline to stakeholders effectively?
