multi-tool-handofflisted

# Multi-tool handoff Keep coordination, resume context, and delivered history in three root files so agents read only what the current action needs: - `KANBAN.md`: bounded task state; read when selecting, assigning, moving, or finishing work. - `HANDOFF.md`: current unfinished-work context; read only when resuming, transferring, pausing, or approaching a session limit. - `CHANGELOG.md`: durable user-facing delivery history; write on completion and read only for releases or historical review. Do not routinely load all three files. Do not create `HAPPENING_NOW.md` or another duplicate status file. ## Use the bundled files - Copy [assets/kanban-template.md](assets/kanban-template.md), [assets/handoff-template.md](assets/handoff-template.md), and [assets/changelog-template.md](assets/changelog-template.md) when a file is missing. - Read [assets/example.md](assets/example.md) only when formatting guidance is needed. - Read [references/hook-setup.md](references/hook-setup.md) when installing the usage guard for Claude Code, Codex, or Antigravity. ## Maintain `KANBAN.md` Use four columns: Backlog, To Do, In Progress, and Done. Agents move their own cards. Add agent, machine, worktree, and branch metadata only after moving a card to In Progress. Render agent and machine names as flat-square [Shields](https://shields.io/) badges, following `assets/example.md`. Use these stable agent colours: - Codex: `0969da` - Claude: `d97706` - Antigravity: `8250df` - Hermes: `1a7f37` - Oth
