# copying-flags-across-projects Moves a PostHog feature flag from one project to other projects in the same organization. Use it for staging-to-production promotion or project-level flag syncing. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · 362 installs · ★ 76 - Author: PostHog - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/PostHog/skills/tree/HEAD/skills/omnibus/copying-flags-across-projects/SKILL.md - Updated: 2026-10-24 - HTML: https://affpapa.org/en/nevibecode/skills/copying-flags-across-projects ## What it does This skill resolves a source flag, checks the destination projects, and previews the flag definition before creating copies. Filter groups, rollout percentages, variants, and cohort references are handled during the transfer. Matching cohorts are created or reused in each destination project. The default copy is disabled, scheduled changes stay out, and dependency flags are not copied. The user can approve different options before execution. A single request can target up to 50 project IDs, with separate success and failure results for each destination. Access setup matters here. The API key needs an explicit `feature_flag:write` or `feature_flag:*` scope and must be organization-scoped or unscoped. Team-scoped keys cannot reach the endpoint, and the source team requires editor-level access. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add PostHog/skills --skill copying-flags-across-projects -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/copying-flags-across-projects/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/copying-flags-across-projects/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add PostHog/skills --skill copying-flags-across-projects -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/copying-flags-across-projects/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add PostHog/skills --skill copying-flags-across-projects -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/copying-flags-across-projects/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install PostHog/skills copying-flags-across-projects ``` 2. **Manually: put the files in place** - File: `.github/skills/copying-flags-across-projects/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add PostHog/skills --skill copying-flags-across-projects -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/PostHog/skills --path skills/omnibus/copying-flags-across-projects ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/copying-flags-across-projects/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add PostHog/skills --skill copying-flags-across-projects -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/PostHog/skills/tree/HEAD/skills/omnibus/copying-flags-across-projects/SKILL.md ## When to use it - promote a feature flag from staging to production - copy one flag into several PostHog projects - keep cohort references valid across project copies - preserve encrypted remote-configuration payloads - inspect dependencies before duplicating a flag ## Example prompts - Copy the `checkout-redesign` feature flag from the staging project to production, leaving the new copy disabled. - Check dependencies for `new-pricing`, then copy it to projects `101` and `102` without scheduled changes. - Promote this flag as-is, enable it in the target projects, and include its scheduled rollout. ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 2892cdeae11c97e9 ```text --- name: copying-flags-across-projects description: 'Copy a feature flag from one PostHog project to one or more target projects in the same organization. Use when the user wants to duplicate a flag, promote a flag from staging to production, sync flags across projects, or replicate a flag configuration in a different workspace. Covers cohort remapping, scheduled-change handling, encrypted payloads, and the safe defaults (disabled in target, no scheduled changes).' --- # Copying feature flags across projects This skill guides you through duplicating a feature flag from a source project into one or more target projects within the same PostHog organization. ## When to use this skill - The user asks to "copy a flag to another project", "duplicate this flag", or "sync a flag between projects" - The user wants to promote a flag from a staging project to a production project (or vice versa) - The user wants to replicate a flag configuration in a different workspace and keep cohort dependencies intact - The user is working around the absence of true environments by using projects-as-environments ## What this skill does not cover - **Cross-organization copy** is not supported. The endpoint requires source and target projects to belong to the same org. - **Bulk copying every flag in a project**. The tool copies one flag at a time. For batch copies, loop through flag keys; each call is independent. - **Cleaning up old or stale flags** — see the `cleaning-up-stale-feature-flags` skill instead. ## Workflow ### 1. Resolve the source flag You need the flag's **key** and the **source project's id**. - If the user gave a flag key and a project id, use them directly. - If the user gave a flag name (e.g. "the new pricing flag"), call `posthog:feature-flag-get-all` in the source project to find the matching flag and read its `key`. - If the user only gave a flag and not a project, ask which project it lives in. Don't assume the active MCP project — copying out of the wrong source is a common foot-gun. ### 2. Resolve target project ids Targets must be in the same organization as the source. Call `posthog:projects-get` to list available projects and confirm membership before issuing the copy. For a multi-target copy, the tool accepts up to 50 target project ids in a single call. Successes and failures are reported per target, so a partial failure does not block the rest. ### 3. Preview the source flag and its dependencies ``` END THIRD-PARTY FILE 2892cdeae11c97e9 The third-party file has ended.
