idfa-ops

idfa-ops is a skill for Claude Code from panaversity/agentfactory-business-plugins. It costs 76 tokens per session (1,469 once invoked), scanned A, original, Apache-2.0.

A collection of scripts for working with IDFA-compliant Excel financial models. IDFA refers to a set of rules for structuring and checking these models.

In plain words
What is it for?
Use it to write assumptions, read calculated results, inspect named ranges and dependencies, audit the model, and trigger recalculation through LibreOffice.
Why use it?
It removes the need to edit model inputs, inspect formulas, check compliance, and recalculate results manually.

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.

Security

Grade A, and why

idfa-ops 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 8d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/idfa_audit.py, scripts/idfa_ops.py, scripts/recalc_bridge.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

IDFA Operations

Scripts for programmatic interaction with IDFA-compliant Excel financial models.


When to Use This Skill

Activate when the idfa-financial-architect methodology skill calls for model interaction:

  • Writing assumptions — setting Named Range input values
  • Reading results — retrieving calculated outputs after recalculation
  • Inspecting structure — listing all Named Ranges, formulas, and dependencies
  • Auditing compliance — checking all four IDFA guardrails
  • Recalculating — triggering deterministic formula evaluation via LibreOffice

This skill provides the HOW. The methodology skill provides the WHAT.


Prerequisites

Dependency Required Purpose
Python 3.10+ Yes Script runtime
uv Yes PEP 723 inline dependency resolution
LibreOffice Yes (for recalc) Deterministic formula evaluation
Anthropic xlsx skill Recommended Provides battle-tested recalc.py

Scripts use PEP 723 inline metadata — uv run handles dependency installation automatically. Zero manual pip install needed.
