audit-agents
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
Gentleman-Programming
Vercel AI SDK 5 patterns. Trigger: When building AI chat features - breaking changes from v4.
wiki-enrich
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
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
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
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
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
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
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
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
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
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
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
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.
setting-up-support-slack-locally
PostHog
Connect a real Slack workspace to local PostHog Conversations (the SupportHog Slack app) so Slack messages become support tickets and replies post back. Use when the user wants to test the conversations Slack integration locally, hits "Support Slack OAuth client ID is not configured", gets a white screen or "Network error" on the OAuth callback, or asks how to set SUPPORT_SLACK_APP_CLIENT_ID / a tunnel for supporthog Slack events. Covers the Slack app + scopes, the SUPPORT_SLACK_* dynamic settings, and the key split: localhost for OAuth and the UI, a public tunnel only for inbound events.
depot-ci
PostHog
Configures and manages Depot CI, a drop-in replacement for GitHub Actions that runs workflows entirely within Depot. Use when migrating GitHub Actions workflows to Depot CI, running depot ci migrate, managing Depot CI secrets and variables, running workflows with depot ci run, debugging Depot CI runs with depot ci run list, depot ci status, depot ci logs, depot ci diagnose, or depot ci ssh, inspecting test results with depot tests or run artifacts with depot ci artifacts, checking workflow compatibility, or understanding Depot CI capabilities. Also use when the user mentions .depot/ directory, depot ci commands, or asks about running GitHub Actions workflows on Depot's infrastructure without GitHub-hosted runners. Also use when comparing what Depot CI and GitHub Actions report for a skipped, empty-matrix or continue-on-error job, or when working out whether a check run satisfies a required status check or a merge queue.
querying-production-databases-via-metabase
PostHog
Runs read-only production database analysis through PostHog's internal Metabase instances. Use for ClickHouse query logs, slow query cost, Postgres query plans, index selection, or tenant-size analysis. Covers US and EU database discovery, SSO login through hogli, safe query rules, and query patterns for both engines.
editing-agents-md
PostHog
Decide whether a rule belongs in an AGENTS.md / CLAUDE.md file, and write it so it holds. Use before adding, editing, or removing any instruction in a root or nested AGENTS.md, when a convention keeps getting broken and someone proposes documenting it, when reviewing a diff that touches one, or when a file has grown and needs a trim. Carries the enforcement-tag convention ([lint: <id>] / [review]), the six configuration smells to check against, and the size budget. Trigger terms: AGENTS.md, CLAUDE.md, agent instructions, context file, add a rule, document this convention, the file is too long.
financial-scenario-planner
travisjneuman
Stress-test financial plans across scenarios (bull/bear/base), sensitivity tables, and Monte Carlo-style analysis. Use when evaluating financial assumptions, modeling risk scenarios, or building scenario-based financial plans.
audio-production
travisjneuman
Professional audio production for music, podcasts, and sound design. Use when working with audio recording, mixing, mastering, or sound design for any medium.
game-development
travisjneuman
Game development with Unity, Unreal Engine, and Godot. Use when building games, implementing game mechanics, physics, AI, or working with game engines.
jetbrains-cli-pin
Kilo-Org
Use when pinning or unpinning the CLI version the Kilo JetBrains plugin uses, or fresh-regenerating the local repo CLI. Cleans all leftover CLI binaries and build artifacts in the current worktree so every operation starts from a fresh, artifact-free state.
crabbox-apps
openclaw
Use when asked to open, run, test, or show an app in Crabbox, including native desktops, web previews, and computer use on a temporary machine.
discord-e2e
openclaw
