Posthog Desktop is an agent skill from PostHog/posthog-foss, published by the product's own GitHub organization. Scopes work to the desktop app at products/desktop — a nested standalone pnpm/turbo/Biome workspace imported from the now-archived PostHog/code repo, with posthog/posthog the only source of truth for PRs, CI and publishing, and not part of the root frontend or Django build. Use when the user says /posthog-desktop, or works on the Electron desktop app, apps/code, apps/web, apps/mobile, packages/core, packages/ui, packages/workspace-server, @posthog/api-client, @posthog/agent, or the agent framework. Pins the…
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Backend development, Monorepo tooling and Building AI agents. It works with PostHog, Django, pnpm and GitHub Actions. The repository describes itself as: PostHog FOSS is a read-only mirror of PostHog, with all proprietary code removed. NOTE: This repo is synced automatically from the main PostHog repo. Please raise any issues and… The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 2c48221. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
pnpmnodeFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Posthog Desktop loads about 1.6k tokens when it runs. Until then it costs about 190 tokens; SKILL.md has 646 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/posthog-desktop/SKILL.md (or your agent's skills folder).products/desktop/ is the PostHog desktop app (Electron + agent framework), imported from the
now-archived PostHog/code repo and kept as a nested standalone workspace: own
pnpm-workspace.yaml, own lockfile, own Biome config, Node 22. It is excluded from the root
pnpm-workspace.yaml, from ruff/mypy, from root Jest, from oxlint/oxfmt, from stylelint and
from pytest. posthog/posthog is the only source of truth: PRs, CI and publishing all happen
here, never in PostHog/code.
Read products/desktop/AGENTS.md before writing code
in this tree. It is the source of truth for architecture, layer boundaries, DI, and style.
This skill only covers the scoping contract around it.
Default: everything you read, edit, run and test lives under products/desktop/. Run all
commands with that as cwd. Do not go fishing in frontend/, posthog/, or other products/*
for patterns — the desktop tree has its own, and copying monorepo idioms in is a defect.
Step outside only when one of these is true:
packages/api-client/; the endpoints it hits live in the Django monorepo (see below)..github/workflows/desktop-*.yml, .github/actions/desktop-*/,
.github/scripts/desktop/, and the exclusion entries in pnpm-workspace.yaml,
pyproject.toml, pytest.ini, package.json (lint:css), frontend/jest.config.ts,
.dockerignore, .oxlintrc.json, .oxfmtrc.json, .config/.markdownlint-cli2.jsonc,
.github/workflows/ci-{frontend,storybook,backend}.yml (+ .depot/workflows/ci-backend.yml).
Touch these only to keep an exclusion correct; say so when you do.@posthog/agent, agent-contracts, enricher, git and
harness live in a sibling workspace at packages/agent/ (same toolchain, own lockfile),
because cloud sandboxes boot the agent without the desktop app. Work there, then run
pnpm build:agent from products/desktop/ so desktop's turbo cache sees the change.Anything else outside the tree: stop and ask.
| Root monorepo says | In products/desktop use |
|---|---|
ruff / mypy / pytest | nothing — no Python app code here |
oxlint + Oxfmt, pnpm --filter=@posthog/frontend fix | pnpm lint (Biome check --write), pnpm format |
Jest, hogli test | Vitest (pnpm test), Playwright (pnpm test:e2e) |
pnpm --filter=@posthog/frontend typescript:check | pnpm typecheck (turbo, all packages) |
Kea logics, typegen:write | Zustand stores + InversifyJS services; no kea, no typegen |
LemonUI in frontend/ and products/*/frontend/ | @posthog/quill + Tailwind + Radix Themes |
hogli build:openapi → generated frontend types | packages/api-client/src/generated.ts (hand-maintained here) |
| 4-space / repo Prettier habits | Biome, 2-space, double quotes |
Commands (from products/desktop/): pnpm install, pnpm dev, pnpm build, pnpm typecheck,
pnpm lint, pnpm test, pnpm test:e2e, pnpm --filter <pkg> <task>,
node scripts/check-host-boundaries.mjs.
Never run root-level pnpm install expecting it to cover desktop, and never let a desktop
dependency change alter the root lockfile — the root install must stay byte-identical.
packages/api-client/ calls monorepo endpoints — tasks (/api/projects/:id/tasks/...),
signals, agent applications, environments/MCP installations, /api/users/. When a change needs
the backend:
/improving-drf-endpoints, /django-migrations, serializer help_text, hogli build:openapi).products/desktop/docs/LOCAL-DEVELOPMENT.md.The tree was imported from the standalone PostHog/code repo, which is now archived. There is
no resync process: the monorepo copy is the only maintained one, and fixes land here like any
other monorepo change. product.yaml declares ownership (team-posthog-code) for reviewer
auto-assignment and Slack routing; do not delete it.
products/desktop/.claude/skills/ ships its own: test-electron-app (drive the running app
over CDP :9222), quill-code, storybook-stories, onboarding-videos.
Prefer these over monorepo equivalents while in this tree.

Scopes work to the desktop app at products/desktop — a nested standalone pnpm/turbo/Biome workspace imported from the now-archived PostHog/code repo, with posthog/posthog the only source of truth…. Posthog Desktop is an agent skill from PostHog/posthog-foss, published by the product's own GitHub organization. Scopes work to the desktop app at products/desktop — a nested standalone pnpm/turbo/Biome workspace imported from the now-archived PostHog/code repo, with posthog/posthog the only source of truth for PRs, CI and publishing, and not part of the root frontend or Django build.
Posthog Desktop fits situations like: the user says /posthog-desktop; works on the Electron desktop app; packages/workspace-server; @posthog/api-client.
Run `npx skills add PostHog/posthog-foss --skill posthog-desktop -a claude-code`. Or copy the skill folder (.agents/skills/posthog-desktop in PostHog/posthog-foss) into .claude/skills/posthog-desktop in your project. Claude Code loads it when a task matches its description.
Run `npx skills add PostHog/posthog-foss --skill posthog-desktop -a codex`. Or copy the skill folder (.agents/skills/posthog-desktop in PostHog/posthog-foss) into .agents/skills/posthog-desktop in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add PostHog/posthog-foss --skill posthog-desktop -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/posthog-desktop, .gemini/skills/posthog-desktop, .github/skills/posthog-desktop and .opencode/skills/posthog-desktop in your project.
Going by SKILL.md and its folder, Posthog Desktop needs the command-line tools its instructions call (pnpm and node). Our summary lists: Python 3.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Posthog Desktop is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
