What it does
Interceptor macOS is an agent skill from Hacker-Valley-Media/Interceptor. Drive native macOS apps via interceptor macos : AX trees, background click/type/keys/drag/scroll, occluded or minimized window capture, browser chrome, URL bars, OS dialogs, Apple Events, trusted OS input, monitor/replay, overlays, vision, speech, NLP, JSC host utilities, Electron app web-content control via interceptor macos cdp, and in-process app runtime control via interceptor macos runtime. Background-first by contract; only app activate and open --activate move focus. Use for native apps, named browser app…
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including reference files (for example `references/accessibility-and-input.md`, `references/advanced-domains.md` and `references/background-first.md`).
It sits in Productivity & Automation, covering Natural language processing. It works with macOS, Electron and Model Context Protocol. The repository describes itself as: Browser automation and computer use for AI agents. One CLI and MCP server for your signed-in browser, native macOS apps, and real iPhones.
When your agent uses it
- Named browser app routing
- Tasks that involve Natural language processing
Example prompts
- “/interceptor-macos”
What it can do on your machine
Read from SKILL.md and the folder at commit ab6772f. 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
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
Interceptor macOS loads about 2k tokens when it runs, and up to ~21k if it reads all its reference files. Until then it costs about 158 tokens; SKILL.md has 759 words of instructions outside code blocks.
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 759 words (~2,014 tokens).
“Reserved namespace: .agents/skills/interceptor-windows/ is reserved for a future Windows surface (UIA, Win32 input, ETW). It does not exist yet — do not stub it. -->”

When should I use Interceptor macOS?
Interceptor macOS fits situations like: named browser app routing; tasks that involve Natural language processing.
How do I install Interceptor macOS in Claude Code?
Run `npx skills add Hacker-Valley-Media/Interceptor --skill interceptor-macos -a claude-code`. Or copy the skill folder (.agents/skills/interceptor-macos in Hacker-Valley-Media/Interceptor) into .claude/skills/interceptor-macos in your project. Claude Code loads it when a task matches its description.
How do I install Interceptor macOS in Codex?

Can I use Interceptor macOS 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 Hacker-Valley-Media/Interceptor --skill interceptor-macos -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/interceptor-macos, .gemini/skills/interceptor-macos, .github/skills/interceptor-macos and .opencode/skills/interceptor-macos in your project.
What does Interceptor macOS need to run?
SKILL.md names no scripts, command-line tools or credentials: Interceptor macOS is instructions for the agent only.
