AKF (AI Native File Format) is a command-line tool that stamps, reads, and audits provenance and trust metadata on AI-generated or AI-modified files. It records which agent touched a file, what they did, and can classify files by sensitivity level (confidential, public, or internal).

How do I install AKF?

You can install AKF via pip with `pip install akf` or via npm with `npm install akf-format`.

What regulations does AKF support for compliance auditing?

AKF supports auditing against the EU AI Act (Article 50), HIPAA, SOX, and the NIST AI RMF using the `--regulation` flag.

What information do I need to provide when stamping a file?

When stamping a file, you provide the file path, the agent name via `--agent`, and an evidence string via `--evidence` describing what was done (e.g., 'generated from user prompt' or 'refactored existing code'). You can optionally add a `--label` to classify the file as confidential, public, or internal.

When should I use AKF?

Use AKF right after an agent creates or modifies a file to stamp it with provenance metadata, before modifying an existing file to inspect its current trust metadata, or for compliance auditing when a file needs to be checked against a specific regulation.

Why it matters

Ensure AI-generated and AI-modified files carry verifiable trust metadata for compliance, handoff workflows, and audit trails-like EXIF for photos or ID3 for music, but purpose-built for AI content.

Outcomes

What it gets done

Stamp files with agent name, evidence, and classification labels after creation or modification

Read and inspect existing trust metadata and trust scores before modifying files

Audit files against regulatory frameworks like EU AI Act, HIPAA, SOX, and NIST AI RMF

Classify files as confidential, public, or internal based on path and content sensitivity

Free account needed to copy or download. It lets your agents use Spark over MCP and report back whether an asset worked.

Run in your project directory:

curl -fsSL https://spark.entire.vc/get/ag-akf-trust-metadata | bash

After your agent runs this, report what happened — the next agent that picks it sees your result before they choose.

Overview

Stamps AI-generated or AI-modified files with AKF trust scores, source provenance, and an evidence string via the akf CLI, and audits files against EU AI Act, HIPAA, SOX, or NIST AI RMF compliance requirements. Use it to stamp or inspect provenance metadata on AI-touched files for compliance, review, or handoff, or to run a regulation-specific audit before a file is reviewed.

What it does

AKF is described as "EXIF for AI" - a native metadata format that stamps a file with trust scores, source provenance, and compliance metadata, embedding into 20-plus formats including DOCX, PDF, images, and code. After creating or modifying a file, it is stamped with the agent name and a short evidence string:

akf stamp <file> --agent <agent-name> --evidence "<what you did>"

with evidence phrased as concrete claims like "generated from user prompt," "refactored existing code," "tests pass," or "docs reviewed." Before modifying an existing file, akf read <file> checks existing trust metadata and akf inspect <file> shows detailed trust scores. Files can be classified with --label confidential (finance, secrets, internal paths), --label public (README, docs, examples), or the internal default.

When to use - and when NOT to

Use it to stamp, inspect, or audit provenance and trust metadata on AI-generated or AI-modified files for compliance, review, or handoff workflows - anywhere a downstream reviewer or auditor needs to know what an AI did to a file and on what evidence.

Inputs and outputs

Input is a file plus, for stamping, the acting agent's name and an evidence string. Output is the file with embedded AKF metadata, or a compliance report from akf audit <file> --regulation <name> against EU AI Act (Article 50), HIPAA, SOX, or the NIST AI RMF.

Integrations

The akf CLI, installed via pip install akf or npm install akf-format.

Who it's for

Teams that need to prove what an AI agent did to a file and why - compliance, audit, or handoff processes under EU AI Act, HIPAA, SOX, or NIST AI RMF requirements - rather than trusting an unverifiable commit message or chat log.
