Borderline

A Claude Code plugin that delegates to the Gemini CLI (gemini) the boring, mechanical, low-risk tasks where Gemini is just as reliable as Claude: bulk translations and i18n, trivial style/color changes, repetitive renames and replacements, boilerplate. The idea: a transparent Claude ⇄ Gemini pipeline, so Claude stays reserved for what needs judgment.

How it works

• borderline skill (skills/borderline/SKILL.md): the brain. It decides what is delegable, picks the mode, launches Gemini and always reviews the result. It auto-activates when it detects a borderline task.
• /borderline <task> command: explicit manual delegation.
• scripts/delegate.sh: a wrapper around gemini with two modes:
  • --edit → Gemini works autonomously in the repo (gemini --yolo --skip-trust -p), reading and writing files. For bulk work (mass i18n).
  • --text → Gemini only returns text (gemini --approval-mode plan -p), never touching files; Claude applies the result. For small changes.

Design decisions (set in this build):

• Hybrid by task: Gemini edits in bulk / returns text for small things.
• Hybrid activation: automatic (skill) + manual (/borderline).
• Always review: Claude verifies the diff before accepting anything.

Requirements

• Gemini CLI installed and on the PATH (gemini --version).
• Claude Code running with --dangerously-skip-permissions, so the pipeline is transparent and doesn't prompt for confirmation on every call.

Installation

# In Claude Code:
/plugin marketplace add BansheeTech/Borderline
/plugin install borderline@borderline-marketplace

Then launch Claude with:

claude --dangerously-skip-permissions

Usage

• Automatic: ask Claude for something borderline ("translate the locales to French", "switch the background to dark mode") and the skill will delegate to Gemini and report back.
• Manual: /borderline translate locales/en.json to locales/de.json.
