MixPanel Analytics Skill

When to Use This Skill

Use this Skill in the Django4Lyfe backend when working with MixPanel analytics tracking in the optimo_analytics module:

• /mixpanel-analytics:implement – to implement new MixPanel tracking events or update existing ones following established patterns (7-step checklist).
• /mixpanel-analytics:review – to review MixPanel implementations for correctness, PII protection, and adherence to Django4Lyfe standards.

Example Prompts

Implement Mode

• "Use /mixpanel-analytics:implement to add a new event for tracking when a user completes their profile setup."
• "Run /mixpanel-analytics:implement svc.surveys.reminder_sent to add tracking for survey reminder notifications."
• "Implement MixPanel tracking for the new HRIS CSV validation feature using /mixpanel-analytics:implement."

Review Mode

• "Run /mixpanel-analytics:review staged to check my staged MixPanel changes for PII violations and pattern compliance."
• "Use /mixpanel-analytics:review branch to audit all analytics changes on this feature branch."
• "Review the entire optimo_analytics module with /mixpanel-analytics:review all."

Modes

This Skill behaves differently based on how it is invoked:

• implement mode – invoked via /mixpanel-analytics:implement:
  • Guides implementation of new MixPanel events through 7 steps.
  • Creates constants, schemas, registry entries, service methods, and tests.
  • Enforces PII protection and code patterns.
• review mode – invoked via /mixpanel-analytics:review:
  • Audits existing implementations for compliance.
  • Checks PII protection, schema design, service patterns, and test coverage.
  • Generates structured review reports with severity tags.

Environment & Context Gathering

When this Skill runs, gather context first:

# Git context
git branch --show-current
git status --porcelain
git diff --cached --name-only | grep -E "optimo_analytics|mixpanel"

# Analytics module stats
grep -c "^    [A-Z_]* = " optimo_analytics/constants.py 2>/dev/null || echo "0"
grep -c "^class Mxp" optimo_analytics/schemas.py 2>/dev/null || echo "0"
grep -c "MixPanelEvent\." optimo_analytics/registry.py 2>/dev/null || echo "0"
ls -1 optimo_analytics/service/*.py 2>/dev/null | xargs -I{} basename {} .py

Read key reference files:

• optimo_analytics/AGENTS.md – module-level rules and PII guidelines
• optimo_analytics/schemas.py – existing schema patterns
• optimo_analytics/service/AGENTS.md – service layer patterns
• optimo_analytics/tests/AGENTS.md – test patterns
• optimo_core/models/login_attribution.py – CTA attribution enums (SlackButtonChoices, SlackTabChoices, TeamsButtonChoices) and URL helpers
• optimo_analytics/docs/LoginCTA_AttributionTestingGuide.md – CTA attribution testing scenarios
• optimo_analytics/docs/BackendMixpanelTestingGuideV2.md – Survey lifecycle & MAP event testing scenarios

Type gate policy:

• Detect Python type checker in this order unless repo docs/CI differ: ty, then pyright, then mypy.
• If ty is configured, it is mandatory and blocking.
• For touched files, do not accept "baseline acceptable" type-check outcomes.
• Read local typing policy docs when present (for example docs/python-typing-3.14-best-practices.md, TY_MIGRATION_GUIDE.md).

Implementation Mode

For the full templates and step-by-step implementation checklist, use:

• references/implementation.md

Checklist (summary):

1. Add event constant (optimo_analytics/constants.py)
2. Create schema (optimo_analytics/schemas.py)
3. Register schema (optimo_analytics/registry.py)
4. Add tracking helper (optimo_analytics/service/{domain}.py)
5. Export helper (optimo_analytics/service/__init__.py)
6. Add tests (optimo_analytics/tests/)
7. Integrate call site in business logic

Critical Rules (Do Not Violate)

• PII: never send names/emails/phones/addresses; identifiers are UUID strings; organization_name is allowed but never logged.
• Fire-and-forget: keyword-only args + try/except wrapper; never let tracking break business logic.
• Event names: {prefix}.{object}.{action}[.error]; do not encode execution context (e.g., "cron") in the event name.
• distinct_id: user UUID → org_<org_uuid> → slack_/apikey_/webhook_; never a raw org UUID.
• Timestamps: Unix ms (datetime_to_timestamp_ms()), not ISO strings.
• is_cron_job: only when tracking-time must align with the original action; include cron_execution_timestamp when set.

Review Mode

For the full checklist, automated checks, and report template, use:

• references/review.md

Summary checklist:

• [P0] PII protection
• [P1] Event registration completeness
• [P1] Schema design + types
• [P1] Service method patterns
• [P2] Test coverage
• [P2] Naming, timestamps, is_cron_job, distinct_id, exports

Compatibility Notes

This Skill is designed to work with both Claude Code and OpenAI Codex.

• Claude Code: install the corresponding plugin and use its slash commands (see plugins/mixpanel-analytics/commands/).
• Codex: install the Skill directory and invoke name: mixpanel-analytics.

For installation, see this repo's README.md.
