Slack File Sharing

Use this command to upload files in Slack:

Upload a file to thread:

prbot slack upload --channel --file --comment "" --thread

Examples: prbot slack upload --channel ${EVENT_CHANNEL} --file ./report.md --comment "Analysis complete" --thread ${QUICK_RESPOND_MSG_TS} prbot slack upload --channel ${EVENT_CHANNEL} --file ./data.json --comment "Here is the data" --thread ${QUICK_RESPOND_MSG_TS}

When to upload files:

  • Reports, analysis results, or documentation (.md, .pdf, .txt)
  • Code samples or scripts (.py, .ts, .js, .sh)
  • Diagrams, screenshots, or visualizations (.png, .jpg, .svg)
  • Data exports or logs (.json, .csv, .log)
  • Any deliverable the user requested

Best practices:

  • ALWAYS upload files to the thread where the user asked the question using --thread parameter
  • Use descriptive file names that indicate the content
  • Include a meaningful comment explaining what the file contains
  • Upload files as soon as they're ready, don't wait until the end
