v0.5.3: persistent session mode via tmux.
- CTASK_SESSION_MODE env var: direct (default) | persistent
- ctask attach: always-tmux entry command
- --direct flag on new/resume/last/open to bypass persistent mode per invocation
- Deterministic session names: ctask-<category>-<slug>-<sha256_6>
- Three entry paths: owner-create, passive reattach, adopted reattach
- Adoption transfers ownership under metadata write lock with race-guard re-check
- v0.4 four-layer concurrency model preserved; Layer 3 selectively skipped on reattach
- Provisional cleanup bypassed in persistent mode (gate UX assumption doesn't translate)
- last-session-summary.json gains 4 optional fields (end_reason, detected_via,
session_ownership, adopted_from_orphan_at)
- Native Windows refuses persistent mode with WSL recommendation; --direct bypass works
- Doctor reports session mode + tmux presence/version when persistent
- v0.4 lease prompt now suggests 'ctask attach <slug>' when a tmux session exists
- User-facing command suggestions use filepath.Base(os.Args[0])
- 21 commits including the polish patch (c204d87)
ctask
A local CLI that creates and manages named AI-agent task workspaces.
ctask gives developers dedicated directories with consistent structure, visible session identity, environment context injection, and automatic session logging -- so you can start, resume, and organize AI-assisted work more safely and predictably.
Status
v0.2.0 -- local use, not published to any package registry. Windows-primary, cross-platform design.
Key Features
- Named workspaces with consistent layout (task metadata, notes, context, output, logs)
- Session traceability -- automatic file-change snapshot logging on every session
- Agent-agnostic -- default agent is Claude Code, but any CLI agent or shell works
- Query resolution -- find workspaces by name, slug, or substring
- Status line -- persistent session context inside Claude Code's UI
- Doctor -- verify setup and diagnose configuration problems
- Safe delete -- active workspace protection prevents accidental data loss

Status Line
ctask includes a status-line helper for Claude Code that shows session context at the bottom of the UI:
(ctask:fix-auth-bug|local) C:\Users\Warren\ai-workspaces\general\2026-04-06_fix-auth-bug
Run ctask doctor to check if the status line is configured. See docs/install.md for setup.
Uninstall
cd C:\Users\Warren\claude_tasks\ctask_v0.1
powershell -NoProfile -ExecutionPolicy Bypass -File scripts/uninstall.ps1
Removes ctask files only. Your workspaces and task data are never touched.
