description	Estimate complexity, effort, and risks for JIRA tickets, features, or projects. Generates structured reports with time estimates, dependencies, risk analysis, and known unknowns. Use when user asks to "estimate", "size", or "analyze complexity" of work items.

JIRA Ticket Estimation Skill

This skill provides structured complexity and effort estimation for JIRA tickets, features, or projects. It produces consistent, professional estimation reports that include complexity levels, time estimates, dependency analysis, risk assessment, and identification of unknowns.

When to Use This Skill

Activate this skill when the user requests:

• "Estimate this JIRA ticket"
• "Analyze complexity of [ticket/feature]"
• "What's the effort for this project?"
• "Size this feature"
• "How long will this take?"
• "What are the risks for this work?"

Prerequisites

• User provides JIRA ticket content (markdown format preferred)
• Access to repository codebase for dependency analysis
• Understanding of project architecture (consult tools/prompts/technology-stack.md if needed)

Workflow

Step 0: Load Required Documentation

Read these files FIRST before any analysis:

1. tools/prompts/guides/jira.md - JIRA quick reference
2. tools/prompts/technology-stack.md - Architecture constraints and patterns
3. CLAUDE.md - Repository conventions and build requirements

After reading, confirm you understand:

• Repository structure and key packages
• Build and test commands
• Architectural constraints (e.g., zero runtime dependencies)

Step 1: Gather and Analyze Ticket Information

Complete ALL before proceeding:

• Receive JIRA ticket content from user (markdown format)
• Extract key requirements, acceptance criteria, and constraints
• Identify the primary affected areas (packages/files)
• Note what information is present vs. missing in the ticket

Initial Analysis Questions:

• What type of work is this? (bug fix, new feature, refactoring, docs, etc.)
• Which packages are affected? (community, enterprise, types, website, etc.)
• Are there related tickets or dependencies mentioned?
• Is the scope well-defined or vague?

Step 2: Identify Ambiguities and Implementation Choices

CRITICAL: Do NOT proceed to estimation without completing this step.

Analyze for ambiguities in these areas:

1. Technical Approach

   • Are there multiple valid implementation strategies?
   • Is the desired architecture/pattern specified?
   • Are performance requirements defined?

2. Scope Boundaries

   • Is the feature scope clearly bounded?
   • Are edge cases and error handling specified?
   • Is backward compatibility required?

3. Integration Points

   • How should this integrate with existing systems?
   • Are framework wrappers (React/Angular/Vue) affected?
   • Are there public API changes?

4. Testing & Quality

   • What level of test coverage is expected?
   • Are visual regression tests needed?
   • Should benchmarks be added/updated?

5. Documentation

   • Is documentation required?
   • Are examples needed?
   • Should migration guides be written?

For each significant ambiguity identified:

• Document the ambiguity clearly
• List the possible implementation choices
• Note how each choice impacts time/complexity/risk
• USE AskUserQuestion tool to get clarification before proceeding

Use the AskUserQuestion tool to present ambiguities:

Present 1-4 ambiguities at once using the AskUserQuestion tool with this structure:

• question: Clear question about the ambiguity (e.g., "How should the 'xy' mode work visually?")
• header: Short label (max 12 chars) (e.g., "Dual-axis UI")
• options: 2-4 implementation choices with:
  • label: Concise option name (e.g., "Two Navigators")
  • description: Impact explanation (e.g., "Show both X-axis (bottom) and Y-axis (right) navigators - 20% more complexity, clearer UI")
• multiSelect: false (user should pick one approach)

Example usage:

AskUserQuestion({
    questions: [
        {
            question: "How should the 'xy' mode work visually?",
            header: 'Dual-axis UI',
            multiSelect: false,
            options: [
                {
                    label: 'Two Separate Navigators',
                    description:
                        'Show both X-axis (bottom) and Y-axis (right) navigators simultaneously - +20% complexity, clearer UI',
                },
                {
                    label: 'Integrated Navigator',
                    description: 'Single unified UI component - High complexity, unclear UX, needs design work',
                },
                {
                    label: 'Not Supported',
                    description: "Only allow 'x' or 'y', defer 'xy' to future ticket - -30% complexity, simpler scope",
                },
            ],
        },
        {
            question: 'Should Y-axis navigator position be configurable?',
            header: 'Position',
            multiSelect: false,
            options: [
                {
                    label: 'Configurable (left/right)',
                    description:
                        'Add navigator.position option - +10% complexity, flexible but may overlap Y-axis labels',
                },
                {
                    label: 'Right Side Only',
                    description: 'Always on right to avoid conflicts - Baseline complexity, simpler but less flexible',
                },
            ],
        },
    ],
});

After receiving answers:

• Document the chosen approach in a summary
• Adjust estimate based on selected options
• Include decisions in the "Implementation Decisions" section of the report

Step 3: Investigate Codebase Dependencies and Complexity

Use the Explore agent for thorough codebase analysis:

• Identify all affected files and packages
• Analyze existing similar implementations for patterns
• Check for dependencies on other systems/modules
• Look for related tests that need updating
• Search for documentation that needs changes

Key Investigation Areas:

1. Core Implementation

   • Where is the main logic located?
   • How complex is the existing code in that area?
   • Are there similar features to reference?

2. Type System

   • Will ag-charts-types need updates?
   • Are there complex type definitions involved?
   • Will this affect public API surface?

3. Testing Surface

   • How many test files are affected?
   • Are image snapshots needed?
   • Will this need E2E tests?

4. Documentation & Examples

   • How many doc pages need updates?
   • Are new examples required?
   • Will framework variants be generated?

5. Build Dependencies

   • Which packages need rebuilding?
   • Are there circular dependency risks?
   • Will this affect build performance?

Completion Checklist

Cannot mark estimation complete until ALL checked:

• User provided JIRA ticket content
• All significant ambiguities identified and clarified with user
• Codebase investigation completed using Explore agent
• All sections of estimation report filled out
• Complexity level justified with rationale
• Time estimate includes breakdown and assumptions
• Top 3 risks identified with mitigation strategies
• Overall risk level assessed
• Report reviewed for completeness and accuracy

Critical Rules

1. NEVER skip ambiguity clarification - If implementation choices significantly impact estimates, you MUST ask the user before proceeding using the AskUserQuestion tool. Better to pause for clarification than provide misleading estimates. Present options with their complexity/time impacts clearly described.

2. Always use AskUserQuestion tool for ambiguities - Do not use ad-hoc text conversation for clarifying implementation choices. Use the structured AskUserQuestion tool to present 1-4 ambiguities at once with clear options and impact descriptions.

3. Always use Explore agent for codebase analysis - Do not attempt complex codebase navigation manually. The Explore agent is optimized for this task.

4. Be honest about uncertainty - If confidence is low, say so clearly. Include what information would increase confidence.

5. Consider the full scope - Don't forget testing, documentation, review iterations, and framework wrappers. These often represent 40-50% of total effort.

6. Account for unknowns - Known unknowns should increase time estimates and risk levels proportionally.

7. Use ranges, not point estimates - Give ranges (e.g., "3-5 days") to reflect uncertainty, especially for complex work.

8. Document assumptions explicitly - Every estimate is based on assumptions. State them clearly so they can be validated.

Failure Handling

Problem: Insufficient ticket information

Solution:

• Request more details from user
• List specific information needed
• Provide estimate with large uncertainty range if user cannot provide more details

Problem: Cannot find relevant code areas

Solution:

• Use Explore agent with broader search patterns
• Ask user for hints about where code might be located
• Document this as a "known unknown" in the report

Problem: Multiple valid implementation approaches with vastly different complexity

Solution:

• Use the AskUserQuestion tool to present each approach as an option
• Include complexity/time impact in each option's description
• Provide recommendation in one option's description if applicable
• Let user select their preferred approach through the structured interface
• Document chosen approach in the "Implementation Decisions" section

Problem: Estimate exceeds reasonable time (e.g., >2 weeks for single person)

Solution:

• Consider if work should be broken into multiple tickets
• Highlight this in the risk assessment
• Recommend creating sub-tasks or phases
• Discuss with user about scope reduction options

Estimation Calibration Data Points

Use these baseline estimates for common AG Charts work items:

Series Implementation

• New series type (extending AbstractBarSeries, CartesianSeries, etc.): 10 days / 2 weeks
  • Includes: Core implementation, type definitions, rendering logic, theme integration
  • Includes: Unit tests, visual regression tests, documentation page, framework examples
  • Examples: Overlapping bar/column series, timeline series, quadrant chart
  • Does NOT include: Highly complex rendering algorithms, advanced interactions beyond standard

Annotation Implementation

• New annotation type: 15-20 days (3-4 weeks)
  • Includes: Core annotation class, rendering, drag/resize interactions, type definitions
  • Includes: Comprehensive testing (unit, E2E, visual regression), documentation, examples
  • Examples: Text annotations, shape annotations, measurement tools
  • Complexity drivers: Drag/drop interactions, resize handles, connection points, styling system

Other Common Work Items

• Simple bug fix (isolated, clear root cause): 0.5-1 day
• Complex bug fix (requires investigation, multiple areas): 2-3 days
• New chart option (simple property, minimal logic): 1-2 days
• Event/callback addition: 2-4 days (depending on complexity)
• Performance optimization: 3-5 days (investigation + implementation)
• Breaking API change: Add 20-30% for migration guide, backward compatibility testing

Adjustment Guidelines:

• Add 20-30% if implementation requires deep integration with multiple systems
• Add 30-50% if feature has significant unknowns or unclear requirements
• Add 40-60% for enterprise features requiring licensing checks, advanced theming
• Reduce by 20-30% only if leveraging substantial existing infrastructure with minimal changes
