Create Flow

Fast, safe flow construction for browser, GUI, and terminal work.

Rules

• One action per run.
• Every action gets a screenshot.
• Every screenshot gets a vision verdict.
• Every verdict is written to the local brain.
• Promotion only happens from evidence.
• If no --root is given, the flow root is auto-detected from the current git repo.
• Screenshot + vision analysis are captured in one step and stored next to the flow evidence.
• Vision analysis must use the Antigravity plugin model google/antigravity-gemini-3-flash directly.
• Never use the direct Gemini API.
• The skill fails fast if the required flash vision path is unavailable.

Canonical tools

CLI

• sin-flow init <flow> — scaffold a flow workspace
• sin-flow step — execute one action + screenshot + vision + brain log
• sin-flow keyshot — screenshot + vision only, writes the same analysis artifacts
• sin-flow record — interactive one-action-at-a-time builder
• sin-flow batch — run a file of single-action steps
• sin-flow status — inspect promotion state
• sin-flow brain — rebuild the brain from evidence
• sin-flow archive — bundle evidence for review/handoff
• sin-flow guard --repo <path> — fail when a repo contains divergent create-flow runtime files outside the canonical SIN-InkogniFlow / upgraded-opencode-stack layouts

Anti-Bot & High-Speed Features

• --mode nodriver executes Python using an internal async context with nodriver boilerplate. It injects the flow_cdp_utils library automatically.
• --fast skips the Vision "Stop & Verify" pause to enable fluid execution (e.g. Mousedown -> Mouseup -> Click) for strict bot protections.
• CDP Helper: Import flow_cdp_utils inside your nodriver script for robust float-scaling on Retina, exact mouse event dispatching, and Context-ID logic for incognito windows.
• Canonical Guard: guard_create_flow.py detects and blocks divergent create-flow runtime files in non-canonical repos.

API

• sin-flowd — local HTTP daemon
• sin-eye — optional ultra-fast vision backend when installed
• POST /v1/flows — create workspace
• POST /v1/flows/<slug>/step — run one step
• POST /v1/flows/<slug>/keyshot — capture + verify only
• GET /v1/flows/<slug>/status — current ladder state
• POST /v1/flows/<slug>/brain — rebuild local brain
• POST /v1/flows/<slug>/archive — archive evidence

Vision chain

Required default:

1. opencode + google/antigravity-gemini-3-flash

No automatic fallback chain is used by default. If the flash path fails, the step fails fast instead of silently switching models.

FLOW_VISION_CMD remains available only for explicit operator overrides.

Flow files

python3 ~/.config/opencode/skills/create-flow/scripts/create-flow.py "My Flow" --root .
python3 ~/.config/opencode/skills/create-flow/scripts/sin-flow.py step "My Flow" --action 'tell application "System Events" to key code 48' --expected 'Tab lands on the target'
python3 ~/.config/opencode/skills/create-flow/scripts/sin-flowd.py --port 8787 --root .

Hard rules

• Never combine steps before evidence proves it.
• Never promote on intuition.
• Never skip the screenshot.
• Never skip the brain write.
• Never override a real STOP from vision.
• You usually do not need look_at for sin-flow output; the step already captures and analyzes the screenshot.
