Jim Bennett d79183139a Add Arize and Phoenix LLM observability skills (#1204)
* Add 9 Arize LLM observability skills

Add skills for Arize AI platform covering trace export, instrumentation,
datasets, experiments, evaluators, AI provider integrations, annotations,
prompt optimization, and deep linking to the Arize UI.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Add 3 Phoenix AI observability skills

Add skills for Phoenix (Arize open-source) covering CLI debugging,
LLM evaluation workflows, and OpenInference tracing/instrumentation.

* Ignoring intentional bad spelling

* Fix CI: remove .DS_Store from generated skills README and add codespell ignore

Remove .DS_Store artifact from winmd-api-search asset listing in generated
README.skills.md so it matches the CI Linux build output. Add queston to
codespell ignore list (intentional misspelling example in arize-dataset skill).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* Add arize-ax and phoenix plugins

Bundle the 9 Arize skills into an arize-ax plugin and the 3 Phoenix
skills into a phoenix plugin for easier installation as single packages.

* Fix skill folder structures to match source repos

Move arize supporting files from references/ to root level and rename
phoenix references/ to rules/ to exactly match the original source
repository folder structures.

# Phoenix Tracing
Comprehensive guide for instrumenting LLM applications with OpenInference tracing in Phoenix. Contains reference files covering setup, instrumentation, span types, and production deployment.
## When to Apply
Reference these guidelines when:
- Setting up Phoenix tracing (Python or TypeScript)
- Creating custom spans for LLM operations
- Adding attributes following OpenInference conventions
- Deploying tracing to production
- Querying and analyzing trace data
## Reference Categories
| Priority | Category | Description | Prefix |
| -------- | --------------- | ------------------------------ | -------------------------- |
| 1 | Setup | Installation and configuration | `setup-*` |
| 2 | Instrumentation | Auto and manual tracing | `instrumentation-*` |
| 3 | Span Types | 9 span kinds with attributes | `span-*` |
| 4 | Organization | Projects and sessions | `projects-*`, `sessions-*` |
| 5 | Enrichment | Custom metadata | `metadata-*` |
| 6 | Production | Batch processing, masking | `production-*` |
| 7 | Feedback | Annotations and evaluation | `annotations-*` |
## Quick Reference
### 1. Setup (START HERE)
- [setup-python](references/setup-python.md) - Install arize-phoenix-otel, configure endpoint
- [setup-typescript](references/setup-typescript.md) - Install @arizeai/phoenix-otel, configure endpoint
### 2. Instrumentation
- [instrumentation-auto-python](references/instrumentation-auto-python.md) - Auto-instrument OpenAI, LangChain, etc.
- [instrumentation-auto-typescript](references/instrumentation-auto-typescript.md) - Auto-instrument supported frameworks
- [instrumentation-manual-python](references/instrumentation-manual-python.md) - Custom spans with decorators
- [instrumentation-manual-typescript](references/instrumentation-manual-typescript.md) - Custom spans with wrappers
### 3. Span Types (with full attribute schemas)
- [span-llm](references/span-llm.md) - LLM API calls (model, tokens, messages, cost)
- [span-chain](references/span-chain.md) - Multi-step workflows and pipelines
- [span-retriever](references/span-retriever.md) - Document retrieval (documents, scores)
- [span-tool](references/span-tool.md) - Function/API calls (name, parameters)
- [span-agent](references/span-agent.md) - Multi-step reasoning agents
- [span-embedding](references/span-embedding.md) - Vector generation
- [span-reranker](references/span-reranker.md) - Document re-ranking
- [span-guardrail](references/span-guardrail.md) - Safety checks
- [span-evaluator](references/span-evaluator.md) - LLM evaluation
### 4. Organization
- [projects-python](references/projects-python.md) / [projects-typescript](references/projects-typescript.md) - Group traces by application
- [sessions-python](references/sessions-python.md) / [sessions-typescript](references/sessions-typescript.md) - Track conversations
### 5. Enrichment
- [metadata-python](references/metadata-python.md) / [metadata-typescript](references/metadata-typescript.md) - Custom attributes
### 6. Production (CRITICAL)
- [production-python](references/production-python.md) / [production-typescript](references/production-typescript.md) - Batch processing, PII masking
### 7. Feedback
- [annotations-overview](references/annotations-overview.md) - Feedback concepts
- [annotations-python](references/annotations-python.md) / [annotations-typescript](references/annotations-typescript.md) - Add feedback to spans
### Reference Files
- [fundamentals-overview](references/fundamentals-overview.md) - Traces, spans, attributes basics
- [fundamentals-required-attributes](references/fundamentals-required-attributes.md) - Required fields per span type
- [fundamentals-universal-attributes](references/fundamentals-universal-attributes.md) - Common attributes (user.id, session.id)
- [fundamentals-flattening](references/fundamentals-flattening.md) - JSON flattening rules
- [attributes-messages](references/attributes-messages.md) - Chat message format
- [attributes-metadata](references/attributes-metadata.md) - Custom metadata schema
- [attributes-graph](references/attributes-graph.md) - Agent workflow attributes
- [attributes-exceptions](references/attributes-exceptions.md) - Error tracking
## Common Workflows
- **Quick Start**: setup-{lang} → instrumentation-auto-{lang} → Check Phoenix
- **Custom Spans**: setup-{lang} → instrumentation-manual-{lang} → span-{type}
- **Session Tracking**: sessions-{lang} for conversation grouping patterns
- **Production**: production-{lang} for batching, masking, and deployment
## How to Use This Skill
**Navigation Patterns:**
```bash
# By category prefix
references/setup-* # Installation and configuration
references/instrumentation-* # Auto and manual tracing
references/span-* # Span type specifications
references/sessions-* # Session tracking
references/production-* # Production deployment
references/fundamentals-* # Core concepts
references/attributes-* # Attribute specifications
# By language
references/*-python.md # Python implementations
references/*-typescript.md # TypeScript implementations
```
**Reading Order:**
1. Start with setup-{lang} for your language
2. Choose instrumentation-auto-{lang} OR instrumentation-manual-{lang}
3. Reference span-{type} files as needed for specific operations
4. See fundamentals-* files for attribute specifications
