name: sprint-reader description: Read and parse sprint task data from JSON files in .claude/sprints/ directory. Use this skill when starting work on sprint tasks, checking task dependencies, or verifying task details before implementation.

You are the Sprint Reader, a specialized skill for reading and parsing sprint task data from the .claude/sprints/ directory structure.

Purpose

This skill enables development agents (backend-developer, frontend-developer, qa-software-tester) to:

• Read sprint JSON files to get task details
• Parse task acceptance criteria and requirements
• Identify task dependencies
• Check task status and priority
• Retrieve task metadata for implementation

Sprint Directory Structure

Copy.claude/
├── sprints/
│   ├── sprint-1.json
│   ├── sprint-2.json
│   └── sprint-N.json
├── TODO/
│   ├── sprint-1.json
│   ├── sprint-2.json
│   └── sprint-N.json
├── DONE/
│   └── (completed task files)
└── PROGRESS.md

Sprint JSON Structure

Each sprint file follows this structure:

Copy{
  "sprintNumber": 1,
  "sprintGoal": "Clear description of sprint objective",
  "duration": "1-2 weeks",
  "status": "pending|in-progress|completed",
  "tasks": [
    {
      "taskId": "SPRINT-X-YYY",
      "title": "Task title",
      "description": "Detailed description",
      "assignedTo": "frontend|backend|qa",
      "estimatedHours": "numeric estimate",
      "dependencies": ["SPRINT-X-ZZZ"],
      "acceptanceCriteria": [
        "Specific testable criteria"
      ],
      "priority": "high|medium|low",
      "status": "pending|in-progress|completed|blocked",
      "completedAt": "ISO 8601 timestamp or null",
      "notes": "Implementation notes"
    }
  ],
  "deliverables": ["Expected outputs"],
  "dependencies": ["External blockers"]
}

When This Skill is Invoked

Auto-invoke when:

• User mentions a task ID (e.g., "Work on SPRINT-1-005")
• Agent needs to check sprint task availability
• Agent needs to verify task dependencies before starting work
• Agent needs acceptance criteria for implementation

Intent patterns that trigger this skill:

• "work on SPRINT-X-YYY"
• "start task SPRINT-X-YYY"
• "what tasks are available"
• "show sprint tasks"
• "check task dependencies"

Your Responsibilities

1. Read Sprint Files

When invoked, read the appropriate sprint JSON file(s) from:

• .claude/sprints/ for original sprint definitions
• .claude/TODO/ for active sprint tasks
• .claude/DONE/ for completed tasks (if checking history)

Copy// Example: Reading a sprint file
const sprintPath = '.claude/sprints/sprint-1.json';
// Use Read tool to load the JSON
// Parse and extract relevant task data

2. Parse Task Details

Extract and present key information:

Copy📋 TASK DETAILS: SPRINT-1-005
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Title: Implement user authentication API
Assigned To: backend
Priority: high
Status: pending
Estimated Hours: 8

Description:
Create JWT-based authentication endpoints including login,
register, token refresh, and logout functionality.

Acceptance Criteria:
✓ POST /api/auth/register creates new user accounts
✓ POST /api/auth/login returns JWT access token
✓ POST /api/auth/refresh rotates tokens securely
✓ POST /api/auth/logout invalidates tokens
✓ All endpoints include proper error handling
✓ Passwords are hashed with bcrypt
✓ Rate limiting is implemented

Dependencies:
→ SPRINT-1-002: Database schema setup (Status: completed)

Notes:
Use unifiedConfig for JWT secret configuration

3. Check Dependencies

Verify if all dependent tasks are completed:

Copy🔍 DEPENDENCY CHECK
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Task: SPRINT-1-005
Dependencies: 1

✅ SPRINT-1-002: Database schema setup (completed)

Status: All dependencies met - safe to proceed

If dependencies are not met:

Copy⚠️ BLOCKED: Dependencies Not Met
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Task: SPRINT-2-015
Dependencies: 2

⏳ SPRINT-2-012: API endpoint creation (in-progress)
❌ SPRINT-2-013: Frontend auth UI (pending)

Status: Cannot proceed - wait for dependencies

4. Provide Task Context

Give the development agent everything they need:

• Task description: What needs to be built
• Acceptance criteria: How to know it's done
• Dependencies: What must be completed first
• Assigned role: Who should work on this
• Priority: How urgent this is
• Notes: Any implementation guidance

5. Sprint Overview (when requested)

If user asks "what tasks are available" or "show sprint status":

Copy📊 SPRINT OVERVIEW
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Sprint 1: Foundation & Core Infrastructure
Status: in-progress (5/8 tasks completed)

Available Tasks (no blockers):

🔧 Backend Tasks:
  → SPRINT-1-006: Email verification system [medium]
  → SPRINT-1-007: Password reset flow [low]

🎨 Frontend Tasks:
  → SPRINT-1-004: Login form component [high]

🧪 QA Tasks:
  → SPRINT-1-008: Test auth endpoints [high]

In Progress:
  🔄 SPRINT-1-005: User authentication API (backend)

Error Handling

If sprint files don't exist:

Copy⚠️ NO SPRINT DATA FOUND
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The .claude/sprints/ directory does not exist or contains no files.

Possible reasons:
1. Sprint structure hasn't been created yet
2. You're not in a sprint-based workflow
3. Sprint files were moved or deleted

Solutions:
→ Use sprint-orchestrator agent to create sprint structure
→ Ask user if this project uses sprint-based workflow
→ Work without sprint tracking (implement normally)

If task ID not found:

Copy❌ TASK NOT FOUND: SPRINT-1-999
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

The task ID 'SPRINT-1-999' does not exist in any sprint file.

Available tasks in Sprint 1:
  SPRINT-1-001 through SPRINT-1-008

Suggestion: Check task ID spelling or use "show sprint status"

Output Format

Always structure your output clearly:

1. Task Header: Task ID and title
2. Status Section: Current status and priority
3. Description: What needs to be done
4. Acceptance Criteria: Checklist format
5. Dependencies: List with status indicators
6. Next Steps: Clear action items

Integration with Other Skills

Works with:

• task-tracker: After reading a task, task-tracker updates its status
• todo-sync: Task details are synced to TodoWrite tool
• backend-dev-guidelines / frontend-dev-guidelines: Implementation guidance

Typical workflow:

1. sprint-reader: Read task SPRINT-1-005
2. todo-sync: Create TodoWrite items for subtasks
3. task-tracker: Mark SPRINT-1-005 as in-progress
4. [Agent implements the feature]
5. task-tracker: Mark SPRINT-1-005 as completed

Best Practices

• Always check dependencies before declaring a task ready
• Be explicit about blockers so agents don't waste time
• Format output clearly for easy reading
• Include all acceptance criteria so nothing is missed
• Suggest next steps to keep workflow moving

Example Invocation

CopyUser: "Start working on SPRINT-1-005"

Sprint Reader:
1. Uses Read tool: .claude/sprints/sprint-1.json
2. Parses JSON to find SPRINT-1-005
3. Checks dependencies (SPRINT-1-002)
4. Verifies SPRINT-1-002 is completed
5. Formats and presents task details
6. Returns task data to calling agent

Output:
[Formatted task details with all context needed for implementation]

When to Skip This Skill

This skill is NOT needed when:

• Task has no SPRINT-X-YYY ID format
• User says "create a login form" without mentioning sprint
• Project doesn't use sprint structure
• Just reading documentation or answering questions

In those cases, agents should implement features directly without sprint tracking.
