At a glance

Turn any website into a CLI command by driving Chrome's live session.

Works in 3 steps: Install the Browser Bridge extension → Log into target sites in Chrome → Verify

Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Opencli is an agent skill from grandamenium/cortextos. Turn any website into a CLI command by driving Chrome's live session. Use when you need structured data from a site that has no API or where the API is inadequate — reads the browser's actual session (logged-in state, cookies) to extract data. Requires Chrome + Browser Bridge extension setup (one-time).

Its SKILL.md is about 1.4k 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 Marketing & SEO, covering Schema markup. It works with Chrome Extensions. The licence is MIT.

When your agent uses it

Where the API is inadequate — reads the browsers actual session (logged-in state
Cookies) to extract data

Example prompts

“/opencli”

Workflow steps

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

Install the Browser Bridge extension
Log into target sites in Chrome
Verify

What it can do on your machine

Read from SKILL.md and the folder at commit 6f93838. 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 (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
- github.com
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 1.4k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 399 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~78
When it runs · the whole SKILL.md, loaded when a task matches: ~1.4k

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 — Turn Websites Into CLI Commands

Converts any website into a deterministic CLI by driving Chrome's live session. No credentials stored — reuses whatever Chrome is already logged into.

Prerequisites (One-Time Setup)

OpenCLI requires a Chrome extension to bridge between the CLI and the browser.

1. Install the Browser Bridge extension

bash

# Check if already set up
opencli doctor

If not connected:

Download the extension from: https://github.com/jackwener/opencli/releases (look for browser-bridge-extension.zip)
Open Chrome → chrome://extensions → enable Developer Mode
Click Load unpacked → select the extracted extension folder
Run opencli doctor — should show [OK] Extension: connected

2. Log into target sites in Chrome

OpenCLI uses Chrome's existing session. Navigate to the target site in Chrome and log in before running any command.

3. Verify

bash

opencli doctor
# Expected:
# [OK] Daemon: running on port 19825
# [OK] Extension: connected
# [OK] Connectivity: ok

Core Commands

Command	What it does
`opencli doctor`	Diagnose extension connectivity
`opencli explore <url>`	Discover APIs, data stores, and recommended strategies
`opencli generate <url>`	One-shot: explore → synthesize → verify → register adapter
`opencli cascade <url>`	Probe public endpoints before committing to session-based approach
`opencli browser`	Direct page control — navigate, click, type, extract
`opencli record <url>`	Capture API calls from live session → generate YAML candidates
`opencli list`	List all available adapters (87+ built-in)

Adapter Generation Workflow

Use this to build a new adapter for any site:

bash

# Step 1: Explore — discover what the site exposes
opencli explore https://app.example.com \
  --goal "read maintenance work orders and their comments"

# Step 2: Generate — build and register the adapter
opencli generate https://app.example.com \
  --goal "list open work orders with latest comment"

# Step 3: Use it
opencli <adapter-name> list-orders
opencli <adapter-name> get-comments --meld-id 12345

Record-then-synthesize (alternative for complex auth flows)

bash

# Record API calls from your live session
opencli record https://app.example.com

# Perform the actions manually in Chrome while recording
# Stop recording — synthesize converts captured calls to adapter

opencli synthesize propertymeld

Property Meld Adapter Blueprint

Goal: Read meld comments (replacing pm-get-comments.py Playwright script)

Status: Blueprint ready. Requires Chrome extension setup + PropertyMeld login in Chrome to complete.

When extension is connected, run:

bash

# Explore what PropertyMeld exposes
opencli explore https://app.propertymeld.com \
  --goal "read meld work orders and associated comments/notes"

# Generate the adapter
opencli generate https://app.propertymeld.com \
  --goal "list open melds with latest comment for triage"

Expected adapter commands (once generated):

bash

# List open melds
opencli propertymeld list-melds --status open

# Get comments on a specific meld
opencli propertymeld get-comments --meld-id 12345

# Triage summary (all open melds with latest comment)
opencli propertymeld triage --format json

Show full SKILL.md (160 more words)Show less

PropertyMeld API endpoints to target during recording

Based on existing Playwright scripts, these endpoints carry the relevant data:

Endpoint	Data
`/api/v2/melds/`	Work order list, status, assignee, property
`/api/v2/melds/{id}/comments/`	Meld comments and notes
`/api/v2/melds/{id}/`	Single meld detail

Tip: Use opencli record while navigating the Melds page and opening a meld — it captures the actual API calls Chrome makes, which is more reliable than guessing endpoints.

Browser Control (no adapter needed)

For one-off browser interactions without building an adapter:

bash

# Open a session
opencli browser

# Navigate
> navigate https://app.propertymeld.com/melds/

# Extract text from current page
> extract .meld-list-item

# Click a button
> click "View Details"

# Wait for element
> wait .comments-panel

# Get structured data
> extract table --format json

Using Built-In Adapters

87+ adapters ship out of the box:

bash

opencli list              # see all
opencli gh pr list        # GitHub (wraps gh CLI)
opencli obsidian list     # Obsidian vault

Output Formats

All commands support structured output:

bash

opencli propertymeld list-melds --format json
opencli propertymeld list-melds --format csv
opencli propertymeld list-melds --format table   # default

Notes

Session-backed: if Chrome logs out, commands return empty data
Zero LLM cost at runtime — adapters are pre-compiled YAML + JS
Additive: does not replace existing Playwright scripts; use alongside them
opencli cascade first if unsure whether the site has public API endpoints (no extension needed for public routes)

OpenCLI v1.7.3. Daemon runs on port 19825. opencli doctor is the first debugging step for any connectivity issue.
