Skills (Auto-Activated)

The plugin automatically activates when you discuss issue evaluation or PR review. Just ask naturally:

• "Should I accept this feature request?"
• "How should I respond to this issue?"
• "Is this in scope for my project?"
• "Help me triage this pull request"
• "Review this PR for me"
• "Find similar bugs in the codebase"

Commands

Command	Description
/iyu:issue	Systematic issue evaluation with root cause analysis
/iyu:pr	Professional PR review with security awareness
/iyu:run	Plan-driven development execution
/iyu:run-cycle	Adaptive iterative development cycles
/iyu:telemetry-az	Azure App Insights telemetry triage and issue discovery

/iyu:issue

# Triage a GitHub issue
/iyu:issue https://github.com/user/repo/issues/123

# Quick decision only
/iyu:issue https://github.com/user/repo/issues/123 --quick

# Triage and save report
/iyu:issue ./docs/feature-request.md --save

/iyu:pr

# Full PR review
/iyu:pr https://github.com/user/repo/pull/123

# Quick review (critical issues only)
/iyu:pr https://github.com/user/repo/pull/123 --quick

# Security-focused review
/iyu:pr https://github.com/user/repo/pull/123 --security-focus

/iyu:run

# Auto-detect next phase from roadmap
/iyu:run

# Input-driven task execution
/iyu:run "Implement caching layer for API"

# Plan only, no execution
/iyu:run --dry-run

/iyu:run-cycle

# 5 adaptive cycles (default)
/iyu:run-cycle

# 10 cycles with adaptive re-planning
/iyu:run-cycle 10

# Preparation + directional roadmap only
/iyu:run-cycle 5 --dry-run

Each cycle runs Re-plan → Design → Execute → Verify → Reflect → Derive-Next. The roadmap is directional — later cycles may reshape it based on what earlier cycles reveal.

/iyu:telemetry-az

# Analyze Azure Application Insights since the last run, triage, and file issues
/iyu:telemetry-az

# Override the window start
/iyu:telemetry-az --since 2026-05-01T00:00:00Z

# Collect + triage + print report only (no files written, watermark not advanced)
/iyu:telemetry-az --dry-run

# Write the report but create no issue files
/iyu:telemetry-az --no-issues

Reads per-repo settings from claudedocs/telemetry/config.json (App Insights app id + thresholds), resumes from a dedicated watermark file, classifies defects / performance regressions / feature-drop signals, runs issue-triage "1 → 10" discovery aligned with the project philosophy, and files issues only for threshold-crossing findings. Requires az login.

Decision Matrices

Issue Triage:

	Philosophy Aligned	Philosophy Misaligned
High Feasibility	✅ ACCEPT	↗️ REDIRECT
Medium Feasibility	🔄 ADAPT	⏳ DEFER / ↗️ REDIRECT
Low Feasibility	⏳ DEFER	❌ DECLINE

PR Review:

Severity	Meaning
🔴 Blocker	Must fix before merge
🟠 Major	Should fix, or maintainer fixes post-merge
🟡 Minor	Nice to have, non-blocking
✨ Praise	Celebrate good work
