PostHog integration for Next.js App Router applications
llm-analytics-setup
PostHog LLM analytics for all supported providers
posthog-instrumentation
Automatically add PostHog analytics instrumentation to code. Triggers when user asks to add tracking, instrument events, add analytics, or implement feature flags in their codebase.
adding-activity-logging
Adds or changes activity logging (the audit trail) for a Django model in PostHog. Use when a model's writes must show in the Activity side panel or the advanced activity logs, when adding ModelActivityMixin, an ActivityScope, a model_activity_signal receiver, an activity describer, or field exclusions, when auditing which write paths of a model are logged, or when a change is missing from the activity log. Covers the receiver-module convention, writes the signal cannot see (QuerySet.update, bulk_create), the actor outside requests, and product models on a separate database. Trigger terms - activity log, audit log, audit trail, ModelActivityMixin, log_activity, changes_between, activity describer, who changed this.

adding-inbox-sources
Add a new warehouse-backed source to the PostHog Desktop Self-driving Inbox (the feature that ships GitHub, Linear, Zendesk, pganalyze, Jira). A source syncs one warehouse table (issues/tickets/conversations) and a cloud "signals scout" watches it and emits findings. Use when asked to "add a new inbox/self-driving source", "wire up <Jira/GitLab/Sentry/Intercom/Freshdesk/Front/Gorgias/etc> as a signal source", or to extend the source-toggle grid. Covers all three surfaces (posthog/posthog scout emitter + posthog/code UI wiring + the context-mill self-driving wizard skill that offers the source in `npx @posthog/wizard self-driving`), the deploy ordering between them, and created_via attribution.

adding-mcp-store-servers
Add a third-party MCP server (Linear, Notion, GitHub, ...) to the PostHog MCP store catalog. Use when asked to "add X to the MCP store", expand the MCP server marketplace, or fix a broken catalog entry. Covers finding the vendor's remote MCP endpoint, probing it (handshake, OAuth discovery, DCR), authoring the catalog entry in products/mcp_store/backend/catalog.py, verification tiers, and the operator handoff for servers without Dynamic Client Registration.

adding-project-secret-api-key-auth
How to gate a PostHog API endpoint with project secret API key (PSAK) auth — a project-scoped, user-less service credential. Use when adding PSAK support to a viewset action, allowing a new scope for PSAKs, handling synthetic users (ProjectSecretAPIKeyUser), or choosing PSAK-aware rate throttles. Trigger terms: PSAK, ProjectSecretAPIKey, project secret API key, phs_ token, service auth, programmatic endpoint auth.
analyzing-experiment-precompute-canary
Analyze the experiment precompute result-consistency canary across prod-US and prod-EU, deep-dive any issues, and produce an actionable report. Sweeps the canary's Prometheus health gauges in both regions, and when anything is unhealthy pulls the structured divergence/failure logs from Loki to reconstruct exactly which (team, experiment, metric) went wrong, by how much, and which class of divergence it is (stability vs correctness, and for correctness whether exposure counts or only values differ). Mechanism-level root cause needs ClickHouse and is out of scope — the skill hands off with precise drill-down steps. Use when the user asks to check / analyze / verify the experiment precompute canary, investigate a canary divergence or alert, or confirm precomputed experiment results are consistent in production. All data comes through the Grafana MCP (Prometheus + Loki) — no payload decryption, no ClickHouse.

auditing-warehouse-source-coverage
Audit already-implemented Data warehouse import sources for endpoints, schemas, and tables the vendor's API offers but we never wired up. Use when asked whether a source is missing endpoints, to find new endpoints a vendor has added since a source was built, to refresh COVERAGE_GAPS.md, to prioritize which source to deepen next, or to check coverage before an integration review. Covers dumping our real endpoint inventory credential-free, ranking sources by production adoption, diffing against vendor OpenAPI/GraphQL specs, and recording findings. Not for implementing a source (use implementing-warehouse-sources), adding a vendor API version (warehouse-source-new-version), or writing source docs (documenting-warehouse-sources).
authenticating-to-clickhouse
Authenticate a new or changed service to ClickHouse with the rotating ch-podauth ServiceAccount token instead of a static password. Use when adding a service, sidecar, or container that reads or writes ClickHouse, adding a new ClickHouseUser, or hand-building a ClickHouse pool or client for a custom timeout or setting. Covers the token-aware default path (sync_execute, get_client), the rule that a custom pool must pass credential_provider or it silently stays on the static password, wiring the username so the user does not fall back to the default user, and the deploy-side companion in the charts repo. Not for converting an already-deployed user off a static password.

building-product-empty-states
Guide for adding a product setup empty state — the skippable first-run screen a product scene shows until real data arrives, built on the shared ProductEmptyState component. Use when adding an empty state or first-run/setup screen to a product scene, declaring `emptyState` on a `SceneExport`, writing a product setup-status detection logic, building an animated example-data preview widget, or deciding between the scene-level `ProductEmptyState` gate and an inline `ProductIntroduction` panel. Covers the `productSetupStatusLogic` single-layer contract, real-data detection rules, local-only skip semantics, wizard commands, and design tokens.

debugging-local-task-agent-runs
Debug the output of local PostHog task runs — the wizard cloud-run path that executes inside a Docker sandbox under the local Temporal `process-task` workflow (the wizard that integrates PostHog, then the coding agent that commits and opens the PR). Use when a local run looks stuck, failed, or silent, or when you need to read the wizard or agent logs. Covers the `.env.local` keys + `ai_features` intent required for cloud runs locally, finding the task UUID (docker ps, temporal CLI, Temporal UI at localhost:8081), tailing live logs inside the sandbox container (`/tmp/posthog-wizard.log`, `/tmp/agent-server.log`), and reading the durable per-run console log from object storage after the sandbox is torn down. Trigger terms: task-sandbox, run_wizard, agent-server, process-task, SANDBOX_PROVIDER, LLM_GATEWAY, cloud_run, posthog-wizard.log.

documenting-warehouse-sources
Write or update the user-facing posthog.com documentation for a PostHog Data warehouse import source. Use when adding a new source doc, fixing an inconsistent or stub source doc, or standardizing the docs at contents/docs/cdp/sources. Covers the canonical template, shared snippets, the auto-rendered <SourceParameters /> and <SourceTables /> components, frontmatter, and the docsUrl/slug rule that prevents 404s.

establishing-code-ownership
Determine which PostHog team owns a file, directory, or code path, or enumerate all code a team owns (via distributed `owners.yaml`, `products/*/product.yaml`, and `.github/CODEOWNERS`). Use when assigning a reviewer, attributing a bug or slow query to a team, routing work, scoping a team-wide audit, or answering "who owns X" / "what does team Y own".
extending-hobby-smoke-tests
Design, extend, review, or debug PostHog Hobby end-to-end smoke tests in bin/hobby-ci.py and .github/workflows/ci-hobby.yml. Use when adding an ingestion round trip, deciding whether a product belongs in Hobby CI, changing the CI Hobby service topology or API-key scopes, or diagnosing a smoke test that captures data but cannot query it.

gating-sensitive-actions
Use when deciding whether an endpoint, settings section, or UI flow should require recent authentication (re-auth), when adding `TimeSensitiveActionPermission` or its exemptions (`time_sensitive_allow_if_only_fields`, `time_sensitive_exclude_actions`, `time_sensitive_allow_actions`), when wrapping a page or settings section in `TimeSensitiveAuthenticationArea`, when an API read returns secret material, or when a write fails with `sensitive_action_required_reauth`. Carries the product decision: reads stay open, only sensitive writes need a fresh session, and the backend enforces it; organization settings are the one area gated on navigation. Covers how the frontend opens the re-auth modal and retries the failed request, and how to test a new gate. Trigger terms: re-auth, reauthenticate, reauthentication, sensitive session, fresh session, sudo mode, step-up, TimeSensitiveActionPermission, TimeSensitiveAuthenticationArea, sensitive_action_required_reauth.

implementing-warehouse-sources
Implement and extend PostHog Data warehouse import sources. Use when adding a new source under products/warehouse_sources/backend/temporal/data_imports/sources, adding datasets/endpoints to an existing source, or adding incremental sync, resumable imports, webhook ingestion, pagination, credentials validation, and source tests.
improving-drf-endpoints
Use when editing, reviewing, or auditing DRF viewsets and serializers in PostHog. Triggers on files in posthog/api/, products/*/backend/api/, products/*/backend/presentation/, or any file importing rest_framework. Covers field typing, schema annotations, enum collision fixes, and OpenAPI spec quality — everything that flows downstream into generated TypeScript types and MCP tools.

instrumenting-first-party-metrics
How to instrument PostHog's own Metrics product from PostHog-owned code — record counters, gauges, and histograms that land in posthog.metrics, the same way customers do. Use when adding application metrics in this monorepo (web, Celery, Temporal), when asked to push or ship metrics into posthog metrics, or when unsure whether the SDK in this environment supports posthog.metrics yet. Covers the environment decision (SDK-first per the public docs, OTel fallback when the SDK path is not available), the exact version gates per SDK, what is already wired internally, and how to validate metrics actually arrive.
