Interceptor

How This Skill Approaches It

Interceptor is a Chrome extension that controls the real browser from inside — no debugger, no CDP, no automation flags. It passes BrowserScan, Pixelscan, CreepJS, and Fingerprint.com because it IS Chrome. It stays logged in because it's the operator's actual profile. A mandatory Preflight Isolation Gate runs before every browser workflow: it checks that the binary is >=0.15.0 and that the dedicated interceptor-test profile is connected — if either fails, the workflow stops rather than falling back to the operator's Default window. Background-first by contract means routine automation never moves focus. The optional macOS bridge extends the same control surface to native apps, OS-level trusted input (bypassing isTrusted checks), VM lifecycle, AX tree reads, ScreenCaptureKit capture, Vision OCR, and Apple Events — all without the raw OS tools that are explicitly forbidden. Compound commands (open, read, act, inspect) collapse multi-step flows into single invocations.

In Action

What you say to your DA, and what the Interceptor skill actually does.

• You say "verify the deploy looks right"
  → Runs VerifyDeploy: checks preflight isolation gate, opens the URL in the interceptor-test Chrome profile via --context interceptor-test, does a structured read plus screenshot, checks for console errors and network failures, and returns evidence of the actual deployed state — logged in, real browser, zero bot detection.
• You say "reproduce this bug i'm seeing on the checkout page"
  → Runs Reproduce: opens the affected page before touching any code, captures console errors and network 404s via interceptor inspect, screenshots the broken state — so you have real evidence of what's actually wrong before you start guessing.
• You say "record this flow so i can replay it as a regression check"
  → Runs RecordFlow via monitor start, captures every browser action as AX events, then exports a deterministic plan script via monitor export --plan that ReplayFlow can execute step-by-step to verify nothing regressed.

Inside the Skill

The thinking, frameworks, and architecture that distinguish this skill from a generic version of the same task.

source "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/LIFEOS/USER/CUSTOMIZATIONS/SKILLS/Interceptor/preferences.env"
bash "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/skills/Interceptor/Tools/EnsureTestProfile.sh"

User: "Verify http://localhost:31337/review renders at 1440 and 390 widths"
→ VerifyDeploy, after `ContextLoad.ts Interceptor load verify` and the preflight
→ One read-back screenshot per width plus page state; every verb carried `--context <id>`

User: "The nav animation stalls when I resize"
→ ScrubFlow, after loading `motion`
→ Evidence from VerifyViewport or a flow gallery, never a hidden-tab measurement

How to Invoke

Say any of these to your DA and LifeOS activates the Interceptor skill automatically:

• "verify deploy"
• "confirm UI"
• "screenshot verification"
• "debug web"
• "visual check"
• "animation bug"
• "console errors"
• "JS errors"
• "network traffic"
• "HAR export"
• "blank-page debug"
• "what is happening on the page"
• "authenticated page"
• "reproduce bug"

Or invoke explicitly:
