What it does
Ink Tui is an agent skill from PostHog/wizard, published by the product's own GitHub organization. Build or modify the PostHog wizard's Ink screens, primitives, keyboard interactions, and session-driven screen flow. Use for TUI work in this repository.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/ARCHITECTURE.md`, `references/PATTERNS.md` and `references/PRIMITIVES.md`).
It works with PostHog. The repository describes itself as: Quickly add PostHog to your project using the setup wizard ✨. The licence is MIT.
When your agent uses it
- TUI work in this repository
Example prompts
- “/ink-tui”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Create the component in src/tui/programs//screens/.
- Add its id to that folder's screen-ids.ts.
- Map the id to the component in the screens of the folder's entry
- Reference it through screenId in the program's flow (flow.ts, or the
What it can do on your machine
Read from SKILL.md and the folder at commit 77055d2. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Shell commands in SKILL.md call:
pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
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.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ink Tui loads about 1.2k tokens when it runs, and up to ~6.3k if it reads all its reference files. Until then it costs about 40 tokens; SKILL.md has 507 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.
Safety
Auto-check passed
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.

Ink TUI
The wizard renders its terminal interface with Ink and React. Pi is an agent harness; it does not replace this renderer. Read wizard-development for architecture and harness/sequence policy before structural changes.
Start with the existing surface
- For screen flow or state, read ARCHITECTURE.md.
- For layout or controls, read PRIMITIVES.md and the relevant component's props.
- For composition and keyboard behavior, read PATTERNS.md.
- For terminal sizing, startup, or noninteractive behavior, read TERMINAL-COMPAT.md.
package.json owns supported versions: currently Node
≥22.22.0, Ink ^6.8.0, React ^19.2.4, and @inkjs/ui ^2.0.0. Use installed
package types for API details; keep this skill focused on the wizard's
conventions rather than copying upstream component manuals.
Add a screen
A screen one program owns:
- Create the component in
src/tui/programs/<id>/screens/. - Add its id to that folder's
screen-ids.ts. - Map the id to the component in the
screensof the folder's entry (index.ts(x)), and add its commits to the harness action registry, or list it inNO_ACTION_SCREENSif it has none. The registry's exhaustiveness test ine2e-harness/__tests__/wizard-ci-driver.test.tsfails a screen in neither. - Reference it through
screenIdin the program's flow (flow.ts, or theAGENT_SKILL_STEPSa skill program adapts), with the appropriate visibility, completion, and gate predicates.
A tool's screens follow the same steps in src/tui/tools/<id>/, whose entry
exports TUI_TOOLS; see src/tools.
A screen several programs or the core use lives in
screens, with its id in
screen-ids.ts and its mount in
screen-registry.tsx. Screen sequences
derive from each program's flow. Do not hand-maintain a second sequence array or
add program navigation to the router. Additional state or service wiring depends
on the screen's needs; App remains the shared shell.

Preserve the UI boundary
Programs never use the UI. They get a runner context from
runner-context.ts. TUI code, the
login included, takes the WizardStore it reports
through as an argument: pushStatus for a line, showOutroError for an error
outro, and abortOnScreens for a decided failure.
There is no UI interface shared with headless or the CLI. Screens use store
setters for reactive changes. The router resolves program screens from step
predicates over the session and the TUI state; overlays interrupt that
resolution. Local state is appropriate for presentation details such as tab
selection, not wizard progression.
For new state, first decide whether it belongs in the shared WizardSession, which extends the ProgramSession programs read, in the TUI's own TuiState when only screens read it, or in display-only store state. Use an explicit setter that notifies subscribers. When TUI code needs a new operation to report through, add it to the store; a run's progress reaches the store through agent-progress.ts. Reuse existing enums and union types rather than introducing competing status vocabularies.
Reuse and check
Compose existing primitives and use styles.ts for shared colors, icons, and alignment. Export new public primitives from primitives/index.ts, add a realistic playground demo, and register it in PlaygroundApp.tsx.
Run pnpm try --playground to inspect primitives. Use
exploring-the-wizard when exercising actual
screen flows. Follow the repository's validation guidance; choose focused
behavior checks for changed predicates or input handling, and visual inspection
for layout changes.

Can I use Ink Tui in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add PostHog/wizard --skill ink-tui -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ink-tui, .gemini/skills/ink-tui, .github/skills/ink-tui and .opencode/skills/ink-tui in your project.
What does Ink Tui need to run?
Going by SKILL.md and its folder, Ink Tui needs the command-line tools its instructions call (pnpm).
Does Ink Tui access the network?
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.
Is Ink Tui safe to install?
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.
What licence does Ink Tui use?
