Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00112 | $0.01020 |
| Opus 5 | $0.00056 | $0.00510 |
| Sonnet 5 | $0.00022 | $0.00204 |
| Haiku 4.5 | $0.00011 | $0.00102 |
Grade A, and why
cursor-cdp-control scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cursor CDP Control
Control Cursor IDE via opencli cursor commands using Chrome DevTools Protocol (CDP).
All commands auto-detect window type:
- Agent window - Cursor 3 standalone Agent window (title = "Cursor Agents")
- Editor window - Traditional editor with embedded Chat panel
Prerequisites
1. Launch Cursor with CDP port enabled
Close all Cursor instances first, then relaunch:
# Windows
"C:\Program Files\cursor\Cursor.exe" --remote-debugging-port=9226
# macOS
/Applications/Cursor.app/Contents/MacOS/Cursor --remote-debugging-port=9226
Notes:
- Must close all Cursor windows before launching (Electron single-instance lock)
- Default port is
9226; customize with--portargument - Do not use the
cursorCLI tool (it invokes cli.js, not the GUI)
2. Install plugin dependencies
cd ~/.opencli/plugins/ksh-plugin-cursor && npm install
3. Verify connection
opencli cursor status

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cursor-cdp-control is a skill published in the GitHub repository toheart/cursor-agent (70 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 112 tokens to every session and 1,020 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
