What problem does it solve? Sharing AI agent session history from a contest repository risks leaking credentials, private content, and machine-local paths; this Skill enforces a scan-export-verify-review-upload pipeline so only sanitized, hash-verified session exports reach the team S3 archive. ## Core Features & Use Cases - Sanitized session export: Scans Codex and Claude Code sessions for a date range, exports them under the canonical proxy submittedBy identity, and flags credential-risk files. - Mechanical verification and review: Validates file hashes, allowed event fields, and absence of credential patterns or absolute paths, then requires a full REVIEW.md content check before upload. - Team impact report: Aggregates all members' exports from an S3 prefix into one HTML timeline of verified score improvements and concurrent session activity. - Use Case: After the contest, run the export for the full date range, verify and review the output, then upload to the team S3 prefix and generate the shared TEAM_TIMELINE.html report. ## Quick Start Use the icfpc-session-archive skill to scan, export, verify, review, and upload my contest sessions for the full contest period.
