Add Bilig WorkPaper plugin

[gregkonush]

1. Metadata

• Plugin Author: proompteng
• Plugin Name: bilig_workpaper
• Repository URL: https://github.com/proompteng/bilig

2. Submission Type

• New plugin submission
• Version update for existing plugin

3. Description

Adds the Bilig WorkPaper tool plugin for Dify. The plugin exposes forecast_formula_readback, which edits a spreadsheet input cell through a configured Bilig WorkPaper OpenAPI endpoint, recalculates formulas, and returns JSON proof that the computed formula output changed and restored readback matches.

This is meant for Dify workflows and agents that need spreadsheet-backed calculation without Excel UI automation or stale XLSX cached values.

4. Checklist

• I have read and followed the Publish to Dify Marketplace guidelines
• I have read and comply with the Plugin Developer Agreement
• I confirm my plugin works properly on both Dify Community Edition and Cloud Version
• I confirm my plugin has been thoroughly tested for completeness and functionality
• My plugin brings new value to Dify

5. Documentation Checklist

• Step-by-step setup instructions
• Detailed usage instructions
• All required APIs and credentials are clearly listed
• Connection requirements and configuration details
• Link to the repository for the plugin source code

6. Privacy Protection Information

Data Collection

The plugin sends the configured Bilig OpenAPI base URL the selected sheet name, cell address, value, and readback range required to run formula readback. It does not collect API keys, user identity, files, workbook uploads, or conversation history.

Privacy Policy

• I confirm that I have prepared and included a privacy policy in my plugin package based on the Plugin Privacy Protection Guidelines

Validation

• Packaged bilig_workpaper-0.1.2.difypkg with the current langgenius/dify-plugin-daemon CLI.
• Package SHA-256: 8bf2136ad8e3c6f3953c55107362b66f03523cbfd17a324ef4880d68118c95f2.
• Unpacked package and verified manifest.yaml: author proompteng, name bilig_workpaper, version 0.1.2.
• Verified package contains README.md, PRIVACY.md, custom icon, provider, tool, requirements.txt, and no __pycache__ or .pyc files.
• Verified requirements.txt pins dify_plugin>=0.5.1,<0.9.0; this keeps Marketplace CI on the SDK line whose package metadata is detected as dify_plugin and whose install method supports serverless.
• Ran Python 3.12 static checks on the unpacked package: py_compile for main.py, provider, and tool files; YAML parsed for manifest/provider/tool definitions.
• Ran a Linux Python 3.12 container check matching the failing CI branch: installed requirements, confirmed pip list reports dify_plugin 0.8.0, confirmed the CI-style version grep detects 0.8.0, confirmed serverless is accepted by dify_plugin, and imported the provider/tool modules.
• Called the public Bilig OpenAPI endpoint and verified formula readback output: verified=true, after.expectedArr=96000, readbackChanged=true, and restoredReadbackMatchesAfter=true.
• Confirmed Marketplace API currently returns plugin version not found for proompteng/bilig_workpaper/0.1.2, so this version does not appear to be already published.

Please address these issues and push an update.

Pushed ec1f5dc to address the install-test failure.

Root cause: tools/forecast_formula_readback.py used Generator[ToolInvokeMessage]. Under Python 3.12 this is invalid because typing.Generator requires yield, send, and return types. The package now uses Generator[ToolInvokeMessage, None, None].

Validation run locally:

unzip -t proompteng/bilig_workpaper/bilig_workpaper-0.1.2.difypkg

PATH=/tmp/bilig-dify-venv/bin:$PATH PYTHONPATH=/tmp/bilig-dify-package-edit INSTALL_METHOD=serverless SERVERLESS_PORT=8080 SERVERLESS_HOST=0.0.0.0 /tmp/bilig-dify-venv/bin/python /tmp/dify-marketplace-toolkit/validator/test-plugin-install.py -d /tmp/bilig-dify-package-edit

Result:

!!! Request to port 8080 successful
!!! Plugin test result: success

The new PR workflow is currently action_required, so it may need maintainer approval before it can rerun on the updated fork commit.
