Trades, project documents, start or required handover date, closures and procurement lead times. The generator uses Python and openpyxl.
Construction scheduling with Claude: check dependencies before the Gantt →
1. Download the native pack
Keep the complete ZIP without extracting it. If already installed and enabled, skip to step 3.
Download the ZIP pack ↓2. Install and enable in Claude
In Customize > Skills, use + > Create skill > Upload a skill to import the ZIP, then enable it. Check code execution and file creation. Attaching Markdown to a chat does not install a skill.
3. Prepare the inputs
Provide known durations, dependencies and permitted overlaps. Separate contractor commitments from assumptions. Identify non-working weeks.
4. Request the file and its assumptions
Request the .xlsx and its config.json. The Gantt is static: changing dates requires updating the configuration and regenerating the file. Ask Claude to disclose if the script was not run.
A request to try
Use my planning-chantier skill and its script. Fictional example: start 5 October 2026; task A lasts 2 weeks, then B lasts 1; closed during the week of 19 October. No overlap allowed. Deliver the Gantt .xlsx and config.json. Check that B starts after A and outside closure. Separate assumptions from confirmed dates.
5. Check the result
- Check every dependency and closure.
- Compare dates, week columns and Gantt bars.
- Keep the configuration with the schedule version.
Files and advanced installation
With Claude Code already installed, run this command in your project terminal, restart Claude Code and invoke the skill with your data.
