    description: PostHog integration for Next.js App Router applications

New format (separate files per group)

Skills live in transformation-config/skills/, one file per group:

integration-skills.yaml (type: example)

type: example
template: integration-skill-description.md
description: PostHog integration for {display_name} applications
shared_docs:
  - https://posthog.com/docs/getting-started/identify-users.md
variants:
  - id: nextjs-app-router
    example_paths: basics/next-app-router
    display_name: Next.js App Router
    tags: [nextjs, react, ssr, app-router, javascript]
    docs_urls:
      - https://posthog.com/docs/libraries/next-js.md

feature-flag-skills.yaml (type: docs-only)

type: docs-only
template: feature-flag-skill-description.md
description: PostHog feature flags for {display_name} applications
tags: [feature-flags]
shared_docs:
  - https://posthog.com/docs/feature-flags/adding-feature-flag-code.md
  - https://posthog.com/docs/feature-flags/best-practices.md
variants:
  - id: react
    display_name: React
    tags: [react, javascript]
    docs_urls:
      - https://posthog.com/docs/feature-flags/installation/react.md

Other group files

• llm-analytics-skills.yaml -- LLM observability skills
• logs-skills.yaml -- Log capture skills
• other-skills.yaml -- Catch-all (e.g. HogQL); variants can override template and shared_docs

Existing groups

Key differences from old format

• variants (not variations) is the key for the list of skills
• type is set at the group level, not per-skill (unless a variant needs to override)
• template is set at the group level; each group has its own SKILL.md template
• shared_docs can be set at group level (shared by all variants) or per-variant
• description at group level uses {display_name} placeholder, substituted per variant
• tags at group level are merged with per-variant tags
• Skill IDs are automatically namespaced: {id}-{category} (e.g. nextjs-app-router in integration-skills becomes nextjs-app-router-integration). The other category skips the suffix.

Migration steps

1. Identify which group each skill belongs to (integration, feature-flag, llm-analytics, logs, or other)
2. Add each skill as a variant in the appropriate transformation-config/skills/{group}-skills.yaml file
3. Remove type from the variant (inherited from group) unless it needs to differ
4. Keep id, display_name, description (optional), tags, docs_urls, and example_paths (for example-type skills)
5. Remove the old flat file
