- Authoring Signals ScoutsHow to author, edit, and adapt PostHog Signals scouts — the scheduled agents that scan a project and emit findings into the Signals inbox. Use when a user wants to customize a canonical scout for their own setup (narrow its scope, retune its thresholds, add disqualifiers), tweak a scout's schedule or dry-run posture, or write a brand-new scout from scratch for a specific use case (a custom event, a product surface no canonical scout covers). Covers the scout SKILL.md anatomy, the emit contrac...Votes: 0GitHub stars: 4
- Auto Type CheckingRun TypeScript type checking after file edits and immediately flag type errors before moving on. Uses Cursor hooks for automatic enforcement.Votes: 0GitHub stars: 4
- Babysitting PrMonitor a pull request for CI failures, review comments, and merge conflicts — then fix them automatically. Use when a PR is open and you want the agent to keep it merge-ready.Votes: 0GitHub stars: 4
- Best Of N SolvingSolve a hard problem by trying multiple approaches in parallel using isolated git worktrees. Each attempt runs in its own branch, and the best solution is selected. Use for complex refactors, tricky bugs, or architectural decisions where multiple strategies could work.Votes: 0GitHub stars: 4
- Building Skills From PatternsWhen the same multi-step workflow repeats in Cursor (user corrections or agent redos), capture it as a new SKILL.md under .cursor/skills/ so future sessions load it automatically.Votes: 0GitHub stars: 4
- Chatcrystal Task WritebackWrite reusable ChatCrystal task memories after substantive work completes. Use when implementation or debugging produced a durable fix, pitfall, pattern, or decision worth preserving, and when the environment can either persist it through `write_task_memory` or emit a structured memory candidate for later save.Votes: 0GitHub stars: 4
- Claude Settings AuditAnalyze a repository to generate recommended Claude Code settings.json permissions. Use when setting up a new project, auditing existing settings, or determining which read-only bash commands to allow. Detects tech stack, build tools, and monorepo structure.Votes: 0GitHub stars: 4

- Configuring Experiment AnalyticsConfigures the analytics side of a PostHog experiment — exposure criteria (default `$feature_flag_called` vs custom exposure events), primary and secondary metrics, the supported metric types (count, sum, ratio with `math` and `math_property`, retention with `retention_window_start` and `start_handling`), multivariate user handling ("Exclude" vs "First seen variant"), and how to read results once the experiment is live. Use when the user adds or edits a primary or secondary metric (e.g. "add ...Votes: 0GitHub stars: 4
- Consuming Endpoints From Client CodeWire a PostHog endpoint into a client app or SDK. Covers fetching the OpenAPI spec, generating a typed client with openapi-generator or @hey-api/openapi-ts, sending the right auth header, shaping the variables payload (HogQL code_name vs insight breakdown property), handling rate-limit and materialised-endpoint error responses. Use when the user says "how do I call my endpoint", "generate a client for this", or "what auth header do I use".Votes: 0GitHub stars: 4

- Converting Css To TailwindConvert plain CSS stylesheets to Tailwind CSS utility classes. Handles selectors, media queries, pseudo-classes, custom properties, and animations.Votes: 0GitHub stars: 4
- Creating Ai SubscriptionCreate a recurring AI-generated PostHog report — schedule a free-text prompt to run on a cron, with the LLM-synthesized markdown delivered to email or Slack on each tick. Use when the user wants a recurring AI summary of X on any cadence (daily, weekly, monthly, yearly) rather than a one-off report. (To attach an AI summary to an existing insight/dashboard subscription instead of a free-text prompt, see `managing-subscriptions` and its `summary_enabled` option.)Votes: 0GitHub stars: 4
- Creating PrCreate a clean, review-ready pull request with a good title, structured description, linked issues, and appropriate reviewers.Votes: 0GitHub stars: 4
- Dark Mode TestingToggle between light and dark mode in Cursor's browser, screenshot both states, and flag missing token mappings or contrast issues.Votes: 0GitHub stars: 4
- Database DesignDesign database schemas — tables, relationships, indexes, constraints, and ORM setup. Covers relational design, normalization, and common patterns.Votes: 0GitHub stars: 4
- Decision MappingTurn a loose idea into a sequenced map of investigation tickets, then drive them to resolution one at a time.Votes: 0GitHub stars: 4
- Designing Email TemplatesAuthor, save, and edit email templates in the PostHog workflows library — compose email design JSON with Liquid personalization and create and round-trip-edit templates over MCP. Use when asked to design, build, update, or fix an email template for workflows, broadcasts, or campaigns.Votes: 0GitHub stars: 4

- Diagnosing Ci And Merge BottlenecksDiagnoses CI and pull-request pipeline health for a GitHub repo using the engineering analytics MCP tools — pull-requests (PR list with CI status), workflow-health (per-workflow CI trends), and pr-lifecycle (a single PR's timeline). Use when asked whether CI is getting faster or slower, which GitHub Actions workflow is the slow or flaky long-pole, how long PRs take from open to merge, how an author's merge time compares to the cohort, which open PRs have failing or pending CI, or where a spec...Votes: 0GitHub stars: 4
- Diagnosing Endpoint PerformanceDiagnose why a PostHog endpoint is slow or expensive and propose a concrete fix — bump the cache TTL, enable materialisation, restructure variables, or rewrite the query. Use when the user says "this endpoint is slow", "my endpoint times out", "we're hitting the cost cap on this one", or asks "should I materialise this?". Focuses on a single named endpoint, not a project-wide audit.Votes: 0GitHub stars: 4
- Exploring Apm TracesInvestigates distributed application performance using PostHog APM (OpenTelemetry span) data via MCP. Use when the user asks about service traces, slow HTTP/database spans, error spans, trace IDs, or span attributes — not AI observability traces or product logs. Uses posthog:query-apm-spans, posthog:apm-trace-get, posthog:apm-services-list, posthog:apm-attributes-list, and posthog:apm-attribute-values-list.Votes: 0GitHub stars: 4
- Exploring Llm ClustersInvestigate AI observability clusters — understand usage patterns in AI/LLM traffic, compare cluster behavior, compute cost/latency metrics, and drill into individual traces within clusters.Votes: 0GitHub stars: 4
- Exploring Llm CostsInvestigate LLM spend in PostHog — total cost over time, cost by model, provider, user, trace, or custom dimension, token and cache-hit economics, and cost regressions. Use when the user asks "how much are we spending on LLMs?", "which model / user / feature is most expensive?", "why did cost spike?", wants to build a cost dashboard or alert, or pastes a trace URL and asks about its cost.Votes: 0GitHub stars: 4
- Exploring Llm EvaluationsInvestigate AI observability evaluations of both types — `hog` (deterministic code-based) and `llm_judge` (LLM-prompt-based). Find existing evaluations, inspect their configuration, run them against specific generations, query individual pass/fail results, and generate AI-powered summaries of patterns across many runs. Use when the user asks to debug why an evaluation is failing, surface common failure modes, compare results across filters, dry-run a Hog evaluator, prototype a new LLM-judge p...Votes: 0GitHub stars: 4
- Exploring Llm TracesABSOLUTE MUST to debug and inspect LLM/AI agent traces using PostHog's MCP tools. Use when the user pastes a trace or session URL (e.g. /ai-observability/traces/<id> or /ai-observability/sessions/<id>), asks to debug a trace, figure out what went wrong, check if an agent used a tool correctly, verify context/files were surfaced, inspect subagent behavior, investigate LLM decisions, or analyze token usage and costs. Also use when raw SQL/HogQL against `events.properties.$ai_input` / `$ai_outpu...Votes: 0GitHub stars: 4
- Exploring Signals ScoutsHow to explore and make sense of PostHog Signals scouts — the scheduled agents that scan a project and emit findings into the Signals inbox. Use when a user wants to understand what scouts they have, how each one is behaving, and whether the fleet is actually working. Covers surveying the fleet and its schedules, reading recent scout runs and drilling into a single run's reasoning, inspecting the durable scratchpad memory the fleet has built up, tracing a run to the findings it emitted, and a...Votes: 0GitHub stars: 4
- Exporting To PngExport code, terminal output, diagrams, or UI components to PNG images using headless browser rendering or CLI tools.Votes: 0GitHub stars: 4
- Finding Dev Server UrlScan running terminals for dev server URLs (localhost ports), report them, and optionally open the app in Cursor's built-in browser.Votes: 0GitHub stars: 4
- Finding Replay For IssueFinds the most informative session recording linked to an error tracking issue. Use when a user has an error tracking issue ID and wants to watch a replay showing what the user was doing when the error occurred. Ranks linked sessions by recency, activity score, and journey completeness, then summarizes the pre-error context. Replaces blind session picking from potentially hundreds of linked recordings.Votes: 0GitHub stars: 4
- Fixing Broken LinksCrawl all links in a file or project, test each for a valid HTTP response, report broken ones, and fix or remove them.Votes: 0GitHub stars: 4
- Form TestingUse Cursor's browser to fill and submit every form in the app with valid and invalid data, verifying validation, error states, and success flows.Votes: 0GitHub stars: 4
- Formatting Insight AxesPick the right y-axis unit when creating or updating a TrendsQuery insight via `posthog:insight-create` or `posthog:insight-update`. Use when the agent is about to add a `formula` purely to convert units (e.g. dividing seconds by 60 to display minutes), when a `math_property` is a duration, currency, ratio, or large count, or whenever the user mentions "format the y-axis", "duration", "seconds", "minutes", "hours", "milliseconds", "ms", "percentage", "currency", "decimals", "axis label", or "...Votes: 0GitHub stars: 4
