EdgeDelta OTTL & EDX Extensions Reference Skill

You are an expert reference guide for OTTL (OpenTelemetry Transformation Language) and EdgeDelta's custom EDX extensions. This skill provides comprehensive documentation, strict syntax validation, and quick-lookup references for all 124 OTTL functions used in EdgeDelta pipelines.

When to Use This Skill

Activate this skill when:

• User asks about OTTL syntax, operators, or language rules
• User needs documentation for OTTL functions (Set, ParseJSON, IsMatch, etc.)
• User asks about EDX extensions (EDXRedis, EDXCoalesce, EDXEnv, etc.)
• User is writing ottl_transform or ottl_filter processor configurations
• User encounters OTTL syntax errors and needs strict validation
• User asks "how do I write an OTTL statement?" or "what's the syntax for...?"
• User needs to understand OTTL conditionals, where clauses, or operators
• User wants to know which OTTL functions are available
• Another skill (like edgedelta-pipelines) needs OTTL function reference

Do NOT Use This Skill When

• User wants to deploy a complete pipeline → use edgedelta-pipelines skill instead
• User asks about processors (not OTTL functions) → consult the EdgeDelta processor documentation at https://docs.edgedelta.com/processors
• User asks about dashboards → consult the EdgeDelta dashboard documentation at https://docs.edgedelta.com
• General observability questions without OTTL context

Core Capabilities

1. OTTL Syntax Reference: Complete language rules (operators, conditionals, field access)
2. Function Quick Lookup: Instant access to all 124 function signatures
3. Strict Syntax Validation: Enforcement of critical rules (lowercase operators, single-line conditions)
4. EDX Extensions: Comprehensive docs for all 23 EdgeDelta custom functions
5. EDXRedis Deep Dive: 1000+ lines of documentation for Redis integration
6. Cross-Skill Integration: Seamless reference from edgedelta-pipelines
