A tool for creating and applying reusable templates to Excel files. Templates define shared layouts, styles, and elements so documents can follow the same structure.

It is for creating spreadsheet templates, applying them to new Excel files, maintaining standard formatting, and documenting template changes.

It removes the need to recreate formatting and document structure for every spreadsheet. Version history and usage guidance help keep templates consistent over time.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00027	$0.00281
Opus 5	$0.00014	$0.00140
Sonnet 5	$0.00005	$0.00056
Haiku 4.5	$0.00003	$0.00028

Security

Grade A, and why

skill-012 scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Requirements for Outputs

Template Management Standards

Template Creation

Users must be able to create templates that define standard layouts, styles, and elements used across various documents.
Example code snippet:

from openpyxl import Workbook

def create_template():
    wb = Workbook()
    ws = wb.active
    ws.title = "Template"
    ws['A1'] = "Header"
    ws['B1'] = "Data"
    return wb

Template Application

Templates should be easily applied to new documents to maintain consistency in presentation.
Example code snippet:

def apply_template(file_path, template):
    wb = load_workbook(file_path)
    # Apply styles from template
    return wb

Documentation and Version Control

Change Documentation

Track changes made to templates over time, including a version history to facilitate updates.
Example: "Version 1.1: Adjusted header styles on 2023-03-01."

User Guidance

Provide comprehensive documentation outlining how to use and modify templates effectively.
Include examples for common scenarios and best practices in template application.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
