You are implementing tasks for sprint "$ARGUMENTS" of this project.

Startup

1. Read kapi/board.md — check for blockers or decisions that affect your work
2. Read kapi/sprints/$ARGUMENTS/tasks.md — find the first unchecked task
3. Read kapi/sprints/$ARGUMENTS/prd.md — understand the sprint goal
4. Post agent init to board.md:
   • Get timestamp: date "+%b %-d %-I%p" | tr '[:upper:]' '[:lower:]'
   • Also create entry file: kapi/entries/{datestamp}-dev-available-v{N}-{task}.md

     ---
     type: available
     role: Dev
     timestamp: {ts}
     title: Dev ready for $ARGUMENTS {T0N}
     ---
     Ready to implement {T0N}: {task title}.
     

   • Add to ## Agent Status in board.md: - **Dev** ($ARGUMENTS, {T0N}) — active {ts}, starting {T0N}: {title}
5. Announce: "Starting {T0N}: {title}"

TDD Cycle (strict — do not skip steps)

For each task:

1. Read — understand what needs to be built (Files, Logic, Test fields in tasks.md)
2. Implement — write the code. For skill files: write the SKILL.md with full instructions
3. Verify — run the Test specified in the task:
   • Build check: npm run build (must pass)
   • Type check: npx tsc --noEmit (must pass)
   • Manual verification as described in the task's Test: field
4. Mark done — change - [ ] to - [x] in tasks.md
5. Commit:

   git add -A
   git commit -m "feat(sprint-$ARGUMENTS): {T0N} - {short description}"
   

6. Move to next unchecked task

When Blocked

1. Add a note: **BLOCKED:** {reason} under the task in tasks.md
2. Write a blocker entry: kapi/entries/{datestamp}-dev-blocker-{slug}.md
3. Add to ## Active Blockers in board.md: - **Dev** — {reason} → entries/{filename}
4. Skip to next task with no unresolved dependencies

When All Tasks Done

1. Run npm run build — must succeed
2. Run npx tsc --noEmit — must succeed
3. Update ## Agent Status in board.md: - **Dev** ($ARGUMENTS) — idle {ts}, all tasks committed, run /test
4. Tell the user: "All tasks done. Run /test $ARGUMENTS to run the QA gate."

Conventions

• Skill files go in .claude/skills/{name}/SKILL.md
• Entry files go in kapi/entries/{YYYY-MM-DD-HHMM}-{role}-{type}-{slug}.md
• Never skip a task silently — always note blockers
• One commit per task
