Patch VS Code's Copilot Chat extension to use MiniMax API instead of Anthropic.

VS Code Copilot Chat has a built-in "Anthropic" provider (BYOK), but it hardcodes https://api.anthropic.com with no way to change the base URL. MiniMax exposes an Anthropic-compatible API at https://api.minimax.io/anthropic, but VS Code won't let you point to it.

Additionally, MiniMax does not implement the /v1/models endpoint that VS Code calls to list available models — causing a 404 error.

This tool patches both issues automatically.

It also supports applying additional custom replacements from a JSON patch file, so you can layer more Copilot extension modifications on top of the MiniMax patch.

1. Redirects all Anthropic API calls from api.anthropic.com → api.minimax.io/anthropic
2. Replaces the model listing call with hardcoded MiniMax model metadata (M2.7, M2.7-highspeed, M2.5, M2.5-highspeed)
3. Creates a backup so you can restore the original at any time

The repository is now modular for easier maintenance and future connector work:

• copilot_minimax_core/cli.py - argument parsing and command routing
• copilot_minimax_core/commands.py - patch/status/restore command handlers
• copilot_minimax_core/patching.py - built-in MiniMax patch logic
• copilot_minimax_core/custom_patches.py - JSON-driven custom patch engine
• copilot_minimax_core/paths.py - OS-specific VS Code path resolution
• copilot_minimax_core/settings_ops.py - optional settings integration
• copilot_minimax.py - compatibility wrapper (python copilot_minimax.py ... still works)
• patches/ - provider-specific patch pack templates (start with Gmail)

For UX direction of future Gmail/Vercel/WhatsApp connector surfaces, see docs/ui-ux-vision.md.

Visual screen-level wireframes are in docs/ui-wireframes.md.

For phased delivery planning, see docs/roadmap.md.

Connector runtime setup is documented in docs/connector-bridge.md.

# No dependencies needed — pure Python 3.9+
git clone https://github.com/akashmahlaz/copilot-minimax.git
cd copilot-minimax

# Check current status
python copilot_minimax.py status

# Apply the patch
python copilot_minimax.py patch

# Apply and also configure Claude Code env vars with your API key
python copilot_minimax.py patch --key YOUR_MINIMAX_API_KEY

# Apply MiniMax patches + your custom patch pack
python copilot_minimax.py patch --patch-file examples/custom_patch.example.json

# Validate built-in + custom patch rules without writing changes
python copilot_minimax.py validate --patch-file patches/gmail.connector.template.json

# Validate concrete connector bridge rules (version-specific)
python copilot_minimax.py validate --patch-file patches/connector.bridge.v1.json

# Validate connector bridge v2 (env-backed endpoint fallback)
python copilot_minimax.py validate --patch-file patches/connector.bridge.v2.json

# Report current patch markers + custom patch match counts
python copilot_minimax.py report --patch-file patches/gmail.connector.template.json

# Apply connector bridge patch pack after validation
python copilot_minimax.py patch --patch-file patches/connector.bridge.v1.json

# Run local mock connector server for end-to-end testing
py -3 tools/mock_connector_server.py

# Or run from repo root with convenience wrapper
py -3 mock_connector_server.py

# Inspect extension.js for stable keyword anchors before writing patch rules
python copilot_minimax.py inspect --keyword gmail --keyword tool --keyword command --limit 8

# Restore original (undo all patches)
python copilot_minimax.py restore

Use --patch-file to apply extra replacements to extension.js after the built-in MiniMax patch logic.

Supported fields for each replacement item:

• name (optional): label shown in output
• find (required): literal string or regex pattern
• replace (required): replacement text
• count (optional): max replacements (default 0 = replace all)
• regex (optional): true to use regex mode
• flags (optional): regex flags string, any of i, m, s

See examples/custom_patch.example.json for the exact format.

For connector work, start from patches/gmail.connector.template.json and replace placeholder find patterns with real extension.js anchors.

For a concrete, version-pinned hook pack built from real internals, see patches/connector.bridge.v1.json.

Use patches/connector.bridge.v2.json for the env-backed bridge URL fallback.

Gmail tool contracts are defined in connectors/contracts/gmail.tools.v1.json.

1. Start mock connector server:

py -3 mock_connector_server.py

2. In a second terminal, set bridge URL and open VS Code:

$env:COPILOT_CONNECTOR_BRIDGE_URL = "http://127.0.0.1:8787/connector/tool"
code .

3. Validate + apply bridge patch:

py -3 copilot_minimax.py validate --patch-file patches/connector.bridge.v2.json
py -3 copilot_minimax.py patch --patch-file patches/connector.bridge.v2.json

4. Confirm current hook status:

py -3 copilot_minimax.py report --patch-file patches/connector.bridge.v2.json

If you previously ran py -3 mock_connector_server.py and saw an error, it was likely because the wrapper file did not exist yet or the terminal cwd was not the repo root.

1. Restart VS Code (close completely and reopen)
2. Go to Language Models (model picker → Manage Models)
3. Click Add Models → select Anthropic
4. Enter your MiniMax API key
5. MiniMax models (M2.7, M2.5, etc.) will appear — select and use!

• ✅ Windows
• ✅ macOS
• ✅ Linux

• No external dependencies — uses only Python standard library
• The patch targets github.copilot-chat-* extension in ~/.vscode/extensions/
• If VS Code auto-updates the Copilot Chat extension, re-run the patch
• Backup is stored as extension.js.copilot-minimax.bak next to the original
