short-description	Event tracking setup
description	Implements Clix event tracking (Clix.trackEvent) with consistent naming, safe property schemas, and campaign-ready validation. Use when adding, reviewing, or debugging event tracking; when configuring event-triggered campaigns; or when the user mentions events, tracking, funnels, or properties — or when the user types `clix-event-tracking`.

Tracking Clix Events

Use this skill to help developers design and implement Clix event tracking via Clix.trackEvent(...) so events can drive event-triggered campaigns, audience filters, and personalization.

What the official docs guarantee (high-signal)

• When to track: identify the user action/system event, then attach meaningful properties (funnel checkpoints, milestones, button taps).
• Property normalization: booleans/numbers/strings map directly; date-like values serialize to ISO 8601; unsupported objects become strings.
• Error handling: event tracking calls can throw—always handle errors so the app stays robust.

MCP-first (source of truth)

If Clix MCP tools are available, treat them as the source of truth:

• clix-mcp-server:search_docs for conceptual behavior (campaign triggers, personalization)
• clix-mcp-server:search_sdk for exact SDK signatures per platform

If MCP tools are not available, use the bundled references:

• Event API contract + pitfalls → references/trackevent-contract.md
• Naming + schemas + privacy → references/naming-and-schema.md
• Implementation patterns → references/implementation-patterns.md
• Campaign mapping → references/campaign-mapping.md
• Debugging checklist → references/debugging.md

Workflow (copy + check off)

Event tracking progress:
- [ ] 1) Confirm platform(s) and goals (analytics vs campaign triggers)
- [ ] 2) Propose event plan (names, when fired, properties, where in code)
- [ ] 3) Validate plan (names, keys, types, PII constraints)
- [ ] 4) Implement trackEvent calls (platform-correct)
- [ ] 5) Verify: events fire once, serialize cleanly, match campaign configs

1) Confirm the minimum inputs

Ask only what’s needed:

• Platform: iOS / Android / React Native / Flutter
• Goal: analytics only, event-triggered campaigns, or both
• Top flows (1–3): e.g., onboarding, checkout, subscription
• PII policy: what must never be sent (email/phone/name/free-text, etc.)

2) Propose an “Event Plan” (before touching code)

Return a compact table the user can approve:

• event_name (stable, snake_case)
• when (exact moment the event fires)
• properties (key + type, mark required vs optional)
• location (file/function/UI handler/network response)
• purpose (campaign trigger / analytics / both)

If campaigns are involved, remind: event names and property keys must match exactly in the Clix console.

3) Validate the plan (fast feedback loop)

Create event-plan.json in .clix/ directory (recommended) or project root:

Recommended location: .clix/event-plan.json

• Organized: keeps tooling configs together
• Hidden: doesn't clutter project root
• Committable: planning document for team review

Alternative: event-plan.json in project root (simpler, but less organized)

For agents: Locate scripts/validate-event-plan.sh in the installed skill directory, then run it:

# From project root:
bash <skill-dir>/scripts/validate-event-plan.sh .clix/event-plan.json
# Or if in root:
bash <skill-dir>/scripts/validate-event-plan.sh event-plan.json

The skill directory is typically:

• .cursor/skills/event-tracking/ (Cursor)
• .claude/skills/event-tracking/ (Claude Code)
• .vscode/skills/event-tracking/ (VS Code)
• .agents/skills/event-tracking/ (Amp)
• Or check where this skill was installed

If validation fails: fix the plan first, then implement.

4) Implement tracking (platform-correct)

Use MCP to fetch the exact trackEvent signature for the platform; then:

• Place calls at stable boundaries (action confirmed, request succeeded, state updated)
• Avoid duplicates (don’t fire on every render; debounce where needed)
• Avoid null/complex values (prefer primitives; serialize dates to ISO)
• Do not track PII by default

See references/implementation-patterns.md for placement heuristics and code patterns.

5) Verify

Minimum verification:

• Event fires exactly once per user action (or the intended cadence)
• Properties are primitive + stable (no null surprises)
• For campaigns: console trigger conditions match exact names/keys

For troubleshooting steps, see references/debugging.md.
