kanban

Shared context: read shared.md for DB path, pipeline levels, status transitions, DB operations, error handling, and agent context flow. Safety principles: read principles.md — mandatory, not optional.

Commands

/kanban or /kanban list — View Board

BOARD_JSON=$(sqlite3 -json "$DB" \
  "SELECT id, title, status, priority, level, current_agent FROM tasks WHERE project='$PROJECT' ORDER BY status, rank, id")

Python으로 column별 그룹화 후 markdown table 출력 (ID, Status, Priority, Title).

/kanban context — Session Handoff

Run first when starting a new session. Fetch board and output pipeline state: Implementing / Plan Review / Impl Review / Testing / Recently Done / Next Todo.

BOARD_JSON=$(sqlite3 -json "$DB" \
  "SELECT id, title, status, priority, level, current_agent FROM tasks WHERE project='$PROJECT' ORDER BY status, rank, id")

/kanban context save — Save Session State

Captures current board state + git branch + decisions made this session to .claude/kanban-context.md. Use before ending a session so the next session can resume without context loss.

BOARD_JSON=$(sqlite3 -json "$DB" \
  "SELECT id, title, status, priority, level FROM tasks WHERE project='$PROJECT' ORDER BY status, rank, id")
BRANCH=$(git branch --show-current 2>/dev/null || echo "unknown")
DIRTY=$(git diff --stat 2>/dev/null | tail -1 || echo "")

Write .claude/kanban-context.md with:

1. Saved at: timestamp + branch
2. In Progress: tasks currently in impl / impl_review / test columns (ID, title, status)
3. Pending Review: tasks in plan_review or impl_review (needs human decision)
4. Next Todo: first task in todo column
5. Git State: branch name, dirty working tree summary ($DIRTY)
6. Decisions this session: ask user "Any decisions to note before saving?" and append their answer verbatim

Add .claude/kanban-context.md to .gitignore if not already present.

/kanban context restore — Restore Session State

Loads .claude/kanban-context.md if it exists, then fetches live board to show what changed since save. Use at session start instead of /kanban context when you were mid-task last session.

SAVED=$(cat .claude/kanban-context.md 2>/dev/null || echo "")
BOARD_JSON=$(sqlite3 -json "$DB" \
  "SELECT id, title, status, priority, level FROM tasks WHERE project='$PROJECT' ORDER BY status, rank, id")

Output:

1. Show saved state (what was in progress, decisions noted)
2. Show current live board state
3. Highlight any status changes since the save (tasks that moved columns)
4. Suggest: "Resume task #ID [title]?" for the first in-progress task

/kanban add <title> — Add Task

1. Ask user for priority, level (L1/L2/L3), description, tags (use AskUserQuestion)
2. Use Python sqlite3 for safe insert with user text (see shared.md → JSON Safety)
3. Output confirmation with new task ID

/kanban move <ID> <status> — Move Task

반드시 shared.md → Move Protocol 순서를 따를 것. Step 1(현재 status+level 확인) → Step 2(매트릭스 조회) → Step 3(유효성 검사 후 이동 실행). 유효하지 않은 전환 시 오류 출력, 사용자에게 올바른 다음 상태 안내.

/kanban edit <ID> — Edit Task

Ask user which fields to modify, then update via sqlite3 CLI.

/kanban remove <ID> — Delete Task

sqlite3 "$DB" "DELETE FROM tasks WHERE id=$ID AND project='$PROJECT'"

/kanban stats — Statistics

/kanban project — Current Project Context

Fetch the current project's context from the projects table.

sqlite3 -json "$DB" "SELECT * FROM projects WHERE id='$PROJECT'"

Output formatted project context: Purpose, Stack, Brief, Category, task counts by status, linked projects.

If the project is not registered, suggest running /kanban-init to register it.

/kanban project all — Full Project Map

sqlite3 -json "$DB" "SELECT id, name, purpose, status, category FROM projects ORDER BY category, name"

Output: projects grouped by category with names and purposes.

/kanban project brief — View/Update Project Brief

The brief is a compressed context summary (200–500 chars) that agents consume at low token cost.

View current brief:

sqlite3 "$DB" "SELECT brief FROM projects WHERE id='$PROJECT'"

Set brief directly:

sqlite3 "$DB" "UPDATE projects SET brief='...' WHERE id='$PROJECT'"

AI-assisted update (/kanban project brief update):

1. Fetch current project info + recent done tasks
2. Analyze: current state, recent completions, active direction
3. Draft a concise brief (200–500 chars) covering: what exists now, where we're heading, recent key decisions
4. Present to user for confirmation → sqlite3 UPDATE to save

/kanban project update <field> <value> — Edit Project Metadata

sqlite3 "$DB" "UPDATE projects SET purpose='...' WHERE id='$PROJECT'"
sqlite3 "$DB" "UPDATE projects SET status='archived' WHERE id='$PROJECT'"

Supported fields: name, purpose, stack, brief, status, category, repo_url.

/kanban project link — Manage Project Relationships

# Add relationship
sqlite3 "$DB" "INSERT OR IGNORE INTO project_links (source_id, target_id, relation) VALUES ('$PROJECT', 'other-project', 'depends_on')"

# Remove relationship
sqlite3 "$DB" "DELETE FROM project_links WHERE source_id='$PROJECT' AND target_id='other-project' AND relation='depends_on'"

# List links
sqlite3 -json "$DB" "SELECT * FROM project_links WHERE source_id='$PROJECT'"

Relations: extends, serves, depends_on, shares_data.

Setup

Run /kanban-init first to create the local SQLite DB and register the project.

Add to .gitignore:

.claude/kanban.json
.codex/kanban.json
.claude/kanban-context.md

DB is stored at ~/.claude/kanban-dbs/<PROJECT>.db — not in the project directory.
