What it does
Bilig Workpaper is an agent skill from sickn33/agentic-awesome-skills. Use formula-backed WorkPaper JSON and MCP tools for agent spreadsheet tasks without driving Excel or a browser UI.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Documents & Office, covering Excel spreadsheets and MCP servers. It works with Microsoft Excel and Model Context Protocol. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

What it can do on your machine
Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are json and typescript).
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
proompteng.github.iogithub.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Bilig Workpaper loads about 1.3k tokens when it runs. Until then it costs about 33 tokens; SKILL.md has 457 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Bilig WorkPaper
Overview
Bilig WorkPaper gives agents a code-first workbook runtime for spreadsheet-style business logic. Use it when the task is easier to model as sheets and formulas, but the reliable path is to edit cells through an API, recalculate, read computed values back, and persist a JSON workbook document.
The main use case is replacing fragile spreadsheet UI automation with deterministic tool calls. It is useful for quote calculators, payout models, budget checks, import validation, and reduced XLSX formula bug reports.
When To Use This Skill
Use this skill when the user needs to:
- work with spreadsheet formulas from a Node.js service, route, test, or agent tool;
- write workbook inputs and verify calculated outputs with readback proof;
- persist a formula workbook as reviewable WorkPaper JSON;
- expose a file-backed workbook through MCP tools;
- investigate an XLSX formula recalculation issue without automating Excel, LibreOffice, or a browser grid.
Do not use it for manual spreadsheet editing, VBA/macros, pivots, charts, COM automation, or exact desktop Excel behavior unless the user explicitly asks to compare against Excel as an oracle.
Safer Command Pattern
Prefer argument arrays in MCP/client configuration. Do not shell-concatenate user-provided paths, sheet names, formulas, or cell addresses. Reject path or cell input containing newlines, backticks, $(, ;, &, |, <, or > before using it in a command.
The MCP examples execute the public @bilig/workpaper npm package. Treat that
as third-party code execution: pin the package version you reviewed, run it only
in a trusted project, and get explicit user approval before starting a writable
MCP server.

Quick MCP Setup
First prove the package-owned challenge works:
{
"command": "npm",
"args": ["exec", "--package", "@bilig/workpaper@<reviewed-version>", "--", "bilig-mcp-challenge"]
}Then run a writable file-backed MCP server:
{
"command": "npm",
"args": [
"exec",
"--package",
"@bilig/workpaper@<reviewed-version>",
"--",
"bilig-workpaper-mcp",
"--workpaper",
"./pricing.workpaper.json",
"--init-demo-workpaper",
"--writable"
]
}Useful tools exposed by the MCP server:
list_sheetsread_rangeread_cellset_cell_contentsget_cell_display_valueexport_workpaper_documentvalidate_formula
After every write, read the dependent output cell and export the WorkPaper document. Do not claim success from the write call alone.
Direct TypeScript Pattern
Use the package directly when workbook logic belongs inside application code:
import {
WorkPaper,
exportWorkPaperDocument,
serializeWorkPaperDocument,
} from "@bilig/workpaper";
const workbook = WorkPaper.buildFromSheets({
Inputs: [
["Metric", "Value"],
["Customers", 20],
["Average revenue", 1200],
],
Summary: [
["Metric", "Value"],
["Revenue", "=Inputs!B2*Inputs!B3"],
],
});
const inputs = workbook.getSheetId("Inputs");
const summary = workbook.getSheetId("Summary");
if (inputs === undefined || summary === undefined) {
throw new Error("Workbook is missing required sheets");
}
workbook.setCellContents({ sheet: inputs, row: 1, col: 1 }, 32);
const revenue = workbook.getCellDisplayValue({ sheet: summary, row: 1, col: 1 });
const saved = serializeWorkPaperDocument(
exportWorkPaperDocument(workbook, { includeConfig: true }),
);
console.log({ revenue, savedBytes: saved.length });Required Verification
A good agent response should include:
- exact sheet names and A1 cells edited;
- before values for important inputs and dependent outputs;
- after values read from the recalculated workbook;
- persistence evidence from exported or serialized WorkPaper JSON;
- restore or reimport proof when file boundaries matter;
- clear limitations for unsupported formulas or Excel-only behavior.
If any proof step fails, report the blocker instead of saying the workbook was updated.
Limitations
- WorkPaper behavior is not a complete replacement for desktop Excel, VBA, pivots, charts, or UI automation.
- Formula compatibility depends on the Bilig runtime and should be verified against Excel when exact parity matters.
- MCP writes should remain scoped to trusted workbook paths and must be followed by readback validation.
