What it does

Portal is an agent skill from BuilderIO/agent-native. Continue a coding session on a paired always-on computer. Use when work must survive closing the primary laptop, needs remote computer-use testing, or should run on a scheduled/self-hosted execution host.

Its SKILL.md is about 1.1k 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 Productivity & Automation, covering Desktop control. The repository describes itself as: A framework for building agentic apps.

When your agent uses it

Work must survive closing the primary laptop
Needs remote computer-use testing
Should run on a scheduled/self-hosted execution host

Example prompts

“/portal”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Select Portal for the coding session and keep the source folder as a Git
Snapshot the current working tree, including dirty tracked and untracked
Queue the run for a paired active host. The run metadata must identify the
On the paired host, fetch the exact commit into a detached Portal worktree
Load the paired host's current local environment files immediately before

What it can do on your machine

Read from SKILL.md and the folder at commit e16da0c. 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

Portal loads about 1.1k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 604 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~53
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

NoteMentions a .env fileSKILL.md:82

- Do not copy `.env` contents or credentials to the source branch or relay.

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 604 words (~1,077 tokens).

Can I use Portal 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 BuilderIO/agent-native --skill portal -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/portal, .gemini/skills/portal, .github/skills/portal and .opencode/skills/portal in your project.

What does Portal need to run?

SKILL.md names no scripts, command-line tools or credentials: Portal is instructions for the agent only.

Does Portal 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.

What licence does Portal use?

No licence was found for Portal or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Portal use?

About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Portal?

Skills that share tags, products or a category with Portal: Vision Skills (Anionex/agent-vision-toolkit, 1.2k stars), Mac Computer Use (To3akaRin/mac-computer-use, 1.1k stars), Crabbox Apps (openclaw/openclaw, 392k stars) and Agent Management (autonomous-ai/Physical-AI-Operating-System, 381 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
