debugging-local-replay
by PostHog
Debugs why session recordings aren't appearing in the local dev environment. Use when a developer reports that local replay ingestion isn't working, recordings aren't showing up despite /s calls, or the replay pipeline seems broken after hogli start. Covers the full local pipeline: SDK capture, Caddy proxy, capture-replay (Rust), Kafka, ingestion-sessionreplay (Node), recording-api (Node), SeaweedFS, and common failure modes like orphaned processes, stuck phrocs workers, and trigger misconfiguration.
styling-sidebar-products
by PostHog
How products and pages appear in the PostHog sidebar: which category they sit in, which icon and color they get, and which groups share a color gradient. Use when adding a product or data management page to the sidebar (treeItemsProducts or treeItemsMetadata in a products/*/manifest.tsx), giving an entry a new icon or color, moving an entry between sidebar categories, adding a category, or when a sidebar icon renders the wrong color, the wrong glyph, or differently once starred. Trigger terms: sidebar, nav, All products, Popular, category, iconType, iconColor, product icon, product color, gradient, starred icon.
debugging-signals-pipeline
by PostHog
Debug the signals pipeline locally end-to-end. Covers emitting test signals from fixtures, monitoring Temporal workflows via the REST API, reading sandbox agent logs from object storage, inspecting Docker sandbox containers, and diagnosing common failures (stale ClickHouse embeddings, agentsh network denials, inactivity timeouts). Use when a signal isn't reaching the inbox, a signal-report-summary workflow fails, or a sandbox task run times out.
routing-outbound-api-calls
by PostHog
Use before adding or changing Python code that calls a third-party HTTP API from PostHog (a vendor REST call, a vendor SDK client, a scraping or enrichment service), and before adding or changing a domain under posthog/egress/: its budget, priority lanes, identity, metrics, or rate-limit headers. Routes the call to an existing egress domain, a new gated domain, a record-only domain, or no domain at all, names the reference domain to copy, and lists the tests that catch a missing priority reserve. Trigger terms: egress, outbound API, third-party API, vendor client, rate limit, 429, Retry-After, budget, priority lane, BATCH, reserve, EgressClient, RecordedEgressClient, github_request.
testing-mcp-tools-locally
by PostHog
Set up the local dev environment, seed data, and API keys to test the staff-only managed migrations MCP tools (managed-migrations-support-list, managed-migrations-support-get) end to end. Use when testing batch import support tooling, debugging MCP tool responses or discovery (tools not appearing), or verifying the support API before deploying. Covers the discovery gate: hidden scope, is_staff, user:read, and why wildcard keys and OAuth never work.
audit-agents
by melodic-software
Audit Claude Code subagents for quality, compliance, and maintainability. Use after creating or modifying agents, before releases, or for periodic quality checks.
ai-sdk-5
by Gentleman-Programming
Vercel AI SDK 5 patterns. Trigger: When building AI chat features - breaking changes from v4.
wiki-enrich
by Learning-Design-Alliance
Enrich ld-wiki stub pages for learning design concepts. Use when asked to enrich, fill in, develop, or create wiki pages for principles, elements, patterns, strategies, theories, or claims.
integrating-with-posthog-ai
by PostHog
'Wire a PostHog product surface into the PostHog AI agent from the frontend. Use when attaching scene or entity context, injecting instructions to steer the agent, reacting to the agent calling a tool, applying an agent edit back into an open form, or rendering a product tool card in a thread.'
developing-subscriptions
by PostHog
Guides PostHog engineers through subscription product changes. Use when changing subscription resource types, destinations, schedules, delivery workflows, retry or automatic disable behavior, permissions, limits, AI summaries, AI prompt reports, delivery history, subscription APIs, MCP tools, or subscription management UI. Not for configuring an existing subscription through MCP.
debugging-mcp-analytics
by PostHog
Debug, support, and build PostHog MCP Analytics — product analytics for MCP servers (the @posthog/mcp and posthog.mcp SDKs plus the mcp_analytics product). Use when MCP analytics data looks wrong or missing ("events aren't showing", "intent clusters are empty", "sessions are missing", "per-tool numbers look wrong"), when writing queries over $mcp_* events by hand, or when doing feature work on the SDKs, the dashboard and its query runners, the self-instrumented MCP server, the wizard mcp-analytics install command, or the in-app onboarding. Covers the repo map, the $mcp_* vocabulary and where each property comes from, the rules that silently corrupt metrics when ignored, the end-to-end pipeline and where each stage breaks, and which repo to change. For reading the data rather than fixing it, prefer the exploring-mcp-* and improving-mcp-tools skills.
authenticating-to-clickhouse
by PostHog
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.
reviewing-with-coderabbit
by PostHog
Run a CodeRabbit review over the branch from the terminal, with the coderabbit CLI, and record the pass in the PR description. Before gh pr create or a requested branch review, first check POSTHOG_TASK_RUN_ID and CI: a cloud or CI task skips this skill without a CLI probe or user message. Otherwise, use this skill to check cr and its authentication, and offer setup or skip when a person can answer. Run the review once per branch. Never substitute an agent review. Trigger terms: coderabbit, cr review, local review, self-review, review my branch, pre-PR review.
adding-activity-logging
by PostHog
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.
profiling-slow-api-endpoints
by PostHog
Profiles slow PostHog API endpoints when the main cost is in Postgres or Python. Use when a screen, picker, or list is slow; a Django endpoint has high tail latency; a query plan changes with tenant size; or a proposed database fix needs production evidence. Covers APM traces, safe production EXPLAIN, representative measurements, implementation choices, tests, rollout, and post-deploy verification. For ClickHouse or HogQL latency, use optimizing-clickhouse-and-hogql-queries instead.
gating-sensitive-actions
by PostHog
'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.'
analyzing-experiment-precompute-canary
by PostHog
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.
improving-mcp-tools
by PostHog
Run an improve-my-MCP campaign: an autoresearch-style loop that measures the MCP agent experience with the eval harness, picks the highest-impact tool problem from production data, makes one bounded fix, and keeps it only if before/after scores improve. Use when asked to "improve my MCP", run an MCP improvement campaign, fix tool discoverability or descriptions based on evidence, or prepare an eval-backed PR for a tool change. Every shipped change must carry eval evidence; guardrails below are hard rules.
working-with-charts
by PostHog
Guides consumers of @posthog/quill-charts through chart selection, data, themes, sizing, and composition. Use when adding or changing a chart built with the package, including its axes, tooltips, legend, overlays, or interactions. Links to package examples and API docs. Does not cover product integration or library internals.
