What it does

Opencli is an agent skill from Peiiii/nextclaw. Use when the user wants to use websites, browser login sessions, Electron apps, or external CLIs through a local OpenCLI setup, especially when setup guidance, readiness checks, and safe task execution are needed.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `marketplace.json`).

The repository describes itself as: A human-centered long-term AI partner—not a task-centered assistant. The licence is MIT.

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Classify the task
Check whether opencli exists
Run readiness check
Apply task-specific prerequisites
Discover supported commands

What it can do on your machine

Read from SKILL.md and the folder at commit d130133. 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:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, 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

Opencli loads about 1.7k tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 869 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~55
When it runs · the whole SKILL.md, loaded when a task matches: ~1.7k

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.

OpenCLI

Overview

Use this skill to help the user work through a local opencli installation from inside NextClaw.

This skill is intentionally decoupled:

The skill owns explanation, onboarding, readiness checks, workflow choice, and risk handling.
opencli owns actual execution.

From the user's point of view, the experience should feel complete:

install or update opencli if needed,
guide the user through browser or app setup,
verify readiness,
then run the real task.

Do not pretend the environment is ready when it is not.

What This Skill Covers

public read-only commands,
browser tasks that reuse the user's Chrome login session,
Electron or desktop app adapters that opencli already supports,
passthrough to external CLIs through opencli,
first-use setup and troubleshooting.

What This Skill Does Not Cover

inventing commands that do not appear in opencli list,
claiming support for a site or app that opencli does not actually expose,
silently bypassing missing setup,
silently triggering destructive or write actions,
treating third-party runtime behavior as native NextClaw behavior.

First-Use Workflow

When the user asks for an opencli-powered task, follow this order.

1. Classify the task

Classify the task into one of these:

public read task,
browser session task,
desktop app task,
external CLI passthrough task.

If the task does not fit any supported opencli shape, say so clearly.

2. Check whether `opencli` exists

Run:

bash

command -v opencli

If missing, explain that opencli must be installed locally first.

Recommended install:

bash

npm install -g @jackwener/opencli

After installation, continue with readiness checks instead of jumping straight into the user task.

3. Run readiness check

Run:

bash

opencli doctor

Use this as the main readiness gate.

If doctor fails, do not proceed to the real task yet. Diagnose the failure first.

4. Apply task-specific prerequisites

For browser session tasks:

Chrome must be running.
The user must already be logged into the target website in Chrome.
The OpenCLI Browser Bridge extension must be installed and enabled.

For desktop app tasks:

The target app must already be installed.
The target app should be open before execution when appropriate.
Do not assume desktop adapters are universally cross-platform; verify command availability first.

For external CLI passthrough tasks:

Verify the target command exists before assuming passthrough is ready.
Example:

bash

command -v gh

opencli documentation says some passthrough commands may attempt auto-install of missing CLIs.
Do not rely on that behavior silently.
If the underlying CLI is missing, explain it and ask for explicit user confirmation before any install path.

5. Discover supported commands

When support is uncertain, run:

bash

opencli list

Prefer:

bash

opencli list -f yaml

when structured inspection is easier.

Only use commands that can be confirmed from the installed opencli command list.

Safe Execution Rules

Prefer read-only commands before write commands.
For writes, posting, deleting, following, publishing, or account-affecting actions, ask for explicit confirmation first.
If the task is exploratory, start with a lightweight read command or status command before a more invasive action.
If the user asks for an unsupported site or command, say it is unsupported instead of improvising.
If opencli doctor or command output indicates missing login, missing extension, or missing app state, stop and guide the user.
Do not bury setup details. Explain the missing prerequisite directly.

Browser Setup Guidance

When browser setup is missing, guide the user through this exact idea:

Install the latest OpenCLI browser extension from the upstream releases page.
Open chrome://extensions.
Turn on Developer mode.
Load the unpacked extension or the unzipped release bundle.
Make sure Chrome stays running.
Log into the target site in Chrome.
Re-run:

bash

opencli doctor

Do not claim browser commands are safe to run before these checks pass.

Privacy And Trust Guidance

When a user is sensitive to privacy or account risk, explain these points clearly:

opencli reuses the user's existing Chrome login state.
Its browser bridge communicates through a local daemon on localhost.
The extension requests browser permissions such as debugger, tabs, cookies, activeTab, and alarms.
The skill should surface this clearly before high-trust tasks.

Do not frame this as "no-risk magic". Frame it as a local tool with explicit browser permissions and explicit account reuse.

Recommended Command Patterns

Use patterns like these:

bash

opencli list
opencli doctor
opencli hackernews top --limit 5
opencli reddit search "AI"
opencli youtube transcript "<url>"
opencli bilibili hot --limit 5
opencli gh pr list --limit 5

If the user wants a specific command and you are unsure whether it exists, check opencli list first.

Troubleshooting

`opencli` not found

Explain that the local CLI is not installed.
Guide the user through installation.
Re-check with command -v opencli.

`doctor` reports extension or daemon problems

Do not continue to the real task.
Guide the user through extension setup and rerun opencli doctor.

Browser command returns empty data or unauthorized behavior

Explain that the most likely cause is missing or expired Chrome login state.
Ask the user to log into the target site in Chrome and try again.

Desktop command fails

Confirm the target app is actually supported.
Confirm the app is open.
Confirm the command exists in opencli list.

External CLI passthrough may install another CLI

Explain that this may modify the local machine.
Ask for explicit confirmation before proceeding.

Success Criteria

The skill is working correctly when:

the user understands what opencli is being used for,
missing setup is identified before task execution,
readiness is checked with opencli doctor,
the user is guided through any required setup,
supported commands are confirmed via opencli list when needed,
and the final task runs only after the environment is truly ready.
