What it does

Gpui is an agent skill from feigeCode/navop. GPUI framework knowledge covering actions/keybindings, async/background tasks, context management (App/Window/Context<T/AsyncApp), custom elements (low-level Element trait), entity state management, event system, focus handling, global state, layout/styling (flexbox/CSS-like), and testing. Use when working with any GPUI framework concept, building GPUI applications, or needing guidance on GPUI-specific APIs and patterns.

Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. The skill folder holds 23 other files, including reference files (for example `references/action.md`, `references/async.md` and `references/context.md`).

It sits in Frontend & Design, covering State management, CSS and styling and Context engineering. The repository describes itself as: A native, all-in-one workspace for databases, SSH, SFTP, terminals, remote desktop, monitoring, and AI.

When your agent uses it

  • Working with any GPUI framework concept
  • Building GPUI applications
  • Needing guidance on GPUI-specific APIs and patterns

Example prompts

  • “/gpui”

What it can do on your machine

Read from SKILL.md and the folder at commit 1cf8b2a. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    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

Gpui loads about 768 tokens when it runs, and up to ~50k if it reads all its reference files. Until then it costs about 108 tokens; SKILL.md has 176 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~768
With references · SKILL.md plus every file in references/, read only if the agent opens them
~50k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 176 words (~768 tokens).
