## Paste this to your agent

Don't install AKF yourself — let your agent do it. Paste this into Claude Code, Cursor, OpenClaw, or any coding agent:

```
Install AKF (pip install akf, or pipx install akf) and set it up: run `akf init --git-hooks`.
From now on:
- After you create or modify a file, stamp it:
    akf stamp <file> --agent <your-id> --evidence "<what you verified, e.g. 42/42 tests passed>"
- Before building on any existing file, check it first:
    akf check <file>
  OK = fresh stamp with verified evidence, skip re-verification. STALE/LOW/UNSTAMPED = verify before trusting.
If you support MCP, also register the server: {"mcpServers":{"akf":{"command":"python","args":["-m","mcp_server_akf"]}}}
```

Your agent installs its own provenance layer — and every file it touches carries trust metadata from then on.

## Why agents need this

Agents redo work constantly: re-read files, re-run tests, re-derive conclusions — because nothing tells them what was already verified. A stamp is cached verification state:

```console
# Session 1 — agent fixes auth, tests pass
$ akf stamp auth.py --agent claude-code --evidence "42/42 tests passed"

# Session 2 — tomorrow, any agent, any tool
$ akf check auth.py
OK trust=0.65 agent=claude-code evidence=test_pass age=1d claims=1
# → build on it, skip re-verification

# Someone edits auth.py without re-testing
$ akf check auth.py
STALE trust=0.65 agent=claude-code evidence=test_pass age=1d claims=1 reason=modified_after_stamp
# → re-verify before trusting (exit code 1 — gate CI or hooks on it)
```

Stamps are trail markers agents leave for other agents — across sessions, across tools (Claude Code → Cursor → Copilot), across teams. Humans get the same trail: who made this file, AI or human, was it tested, can we trust it.

| What travels with the file | How |
|------|-----|
| **Trust score** | 0–1 confidence, weighted by evidence and source tier |
| **Verification evidence** | tests passed, type check clean, human reviewed — with timestamps |
| **Source provenance** | SEC filing → analyst → AI agent chain |
| **Compliance** | One command: `akf audit file --regulation eu_ai_act` |

## Don't trust the stamp — re-run it

A signature proves *who* said it; a replay proves it *could have been true*. A stamp can carry a **falsifiable probe recipe**, so the next agent re-verifies the claim instead of trusting the label:

```console
# Stamp with a recipe that can be re-run
$ akf stamp auth.py --agent claude-code --evidence "42/42 tests passed" --replay "pytest -q"

# Later — re-run the probe instead of trusting the stamp
$ akf replay auth.py --run
CONFIRMED inputs=intact

# A dependency moved since the stamp was written
$ akf replay auth.py --run
CONFIRMED_DRIFTED inputs=drifted   # probe still passes, but against a changed world — re-check
```

`REFUTED` when the probe fails, `UNREPLAYABLE` when there's no recipe. This is the answer to "a trusted source can still be wrong": trust stops depending on who signed it, for any claim with a runnable check.

## Quickstart

```bash
pip install akf    # Python
npm install akf-format    # TypeScript / Node.js

akf doctor         # Check your install — detects PATH issues and guides setup
```

> **`akf` command not found?** Run `akf doctor` to auto-detect your setup, or use `python3 -m akf` (always works).
> - Install with pipx: `pipx install akf` (recommended — auto-handles PATH)
> - **Windows:** use `python3 -m akf` or install via `pipx`

```bash
# The core loop — stamp what you verified, check before you trust
akf stamp auth.py --agent claude-code --evidence "42/42 tests passed"
akf check auth.py        # OK trust=0.65 agent=claude-code evidence=test_pass age=0d
```

```python
import akf

# Same loop from Python
akf.stamp_file("auth.py", agent="claude-code", evidence=["42/42 tests passed"])
result = akf.check_file("auth.py")
print(result.summary_line())   # OK trust=0.65 agent=claude-code evidence=test_pass age=0d claims=1

# Embed into Office docs, PDFs, images — any format
akf.embed("report.docx", claims=[...], classification="confidential")

# Audit for compliance (EU AI Act, HIPAA, SOX, GDPR, NIST AI, ISO 42001)
result = akf.audit("report.akf", regulation="eu_ai_act")
print(f"Compliant: {result.compliant}")
```

**TypeScript / Node.js** (`akf-format`):

```typescript
import { create, validate, effectiveTrust, stampFile } from 'akf-format';

// Create a trust-stamped unit from any AI output
const unit = create('Revenue was $4.2B, up 12% YoY', 0.98, {
  source: 'SEC 10-Q',
  agent: 'claude-code',
});

// Validate against the AKF schema
const { valid } = validate(unit);

// Compute effective trust for a claim
const trust = effectiveTrust(unit.claims[0]);
console.log(`valid: ${valid}, score: ${trust.score}, decision: ${trust.decision}`);

// Stamp trust metadata directly into a file (markdown, json, code, …)
stampFile('report.md', { agent: 'claude-code', evidence: 'tests pass' });
```

> Full TypeScript API and more examples: [`typescript/README.md`](typescript/README.md).

## For AI Agents

AKF is designed **agent-first**. One-line APIs for checking, stamping, streaming, and auditing.

```python
import akf

# Check before you trust — can I build on this file without re-verifying?
result = akf.check_file("auth.py")
if result.status == "OK":      # fresh stamp, verified evidence
    ...                        # skip re-verification, save the tokens
# LOW / STALE / UNSTAMPED → verify before trusting

# Stamp with evidence (auto-detected: test_pass, type_check, human_review, etc.)
akf.stamp("Fixed auth bypass", kind="code_change",
          evidence=["42/42 tests passed", "mypy: 0 errors"],
          agent="claude-code", model="claude-sonnet-4-20250514")

# Stream trust metadata in real-time
with akf.stream("output.md", model="gpt-4o") as s:
    for chunk in llm_response:
        s.write(chunk)

# Trust-annotated git commits (uses git notes)
akf.stamp_commit(content="Refactored auth module", kind="code_change",
                 evidence=["all tests pass"], agent="claude-code")
print(akf.trust_log(n=10))  # + ACCEPT  ~ LOW  - REJECT  ? none
```

## Multi-Agent Teams

AKF supports multi-agent orchestration — Claude Agent Teams, Copilot Cowork, Codex multi-agent, and any A2A-compatible platform.

```python
import akf

# Agent-to-agent delegation with trust ceiling
policy = akf.DelegationPolicy(
    delegator="lead-agent", delegate="research-bot",
    trust_ceiling=0.7, allowed_actions=["search", "summarize"]
)
result = akf.delegate(parent_unit, policy)

# Multi-agent streaming session
with akf.TeamStream(["research", "writer", "reviewer"]) as ts:
    ts.write("research", "Found 3 sources", confidence=0.8)
    ts.write("writer", "Drafted summary", confidence=0.75)
    ts.write("reviewer", "Approved with edits", confidence=0.9)
    scores = ts.aggregate()  # per-agent + team trust

# Cross-platform agent identity
card = akf.create_agent_card(name="Research Bot", platform="claude-code",
                             capabilities=["search", "summarize"])
akf.verify_agent_card(card)  # SHA-256 hash verification

# Team certification (per-agent breakdown)
report = akf.certify_team("src/", min_trust=0.7)
# report.all_agents_certified — each agent must individually pass
```

**CLI:**
```bash
akf agent create --name "Bot" --platform claude-code --capabilities search,summarize
akf agent list
akf agent verify <id>
akf agent export-a2a <id> --output card.json   # A2A protocol bridge
akf agent import-a2a card.json
akf certify src/ --team                         # Per-agent breakdown
```

## MCP Server

AKF ships an [MCP](https://modelcontextprotocol.io) server so any AI agent can create, validate, scan, and audit trust metadata.

```bash
# Install from the repo
pip install ./packages/mcp-server-akf
```

```json
{
  "mcpServers": {
    "akf": {
      "command": "python",
      "args": ["-m", "mcp_server_akf"]
    }
  }
}
```

**11 MCP tools:** `check_file` · `replay_file` · `create_claim` · `validate_file` · `scan_file` · `trust_score` · `stamp_file` · `audit_file` · `embed_file` · `extract_file` · `detect_threats`

## Ambient Trust

AKF works where AI agents work. Drop a config file, and every AI-generated file carries trust metadata automatically.

| Agent | How it works |
|-------|-------------|
| **Claude Code** | Plugin: `/plugin marketplace add HMAKT99/AKF` → `/plugin install akf` — auto-stamp hook + check skill. Or reads `CLAUDE.md` |
| **Cursor** | Reads `.cursorrules` — stamps AI edits before you review |
| **Windsurf** | Reads `.windsurfrules` — stamps AI edits with trust metadata |
| **GitHub Copilot** | Reads `.github/copilot-instructions.md` (native) + shell hook for CLI |
| **OpenAI Codex** | Reads `AGENTS.md` — stamps files in cloud sandbox and local |
| **Any skills-compatible agent** | `npx skills add HMAKT99/AKF` — self-contained check/stamp skill for 18+ agents |
| **OpenClaw** | Skill on ClawHub: `clawhub install akf` — check/stamp protocol + memory trust |
| **Hermes Agent** | agentskills.io skill: `hermes skills tap add HMAKT99/AKF` — files, memories, and skill supply-chain |
| **Manus / Other Agents** | MCP server + shell hook — works with any agent that supports MCP or CLI |
| **Any MCP agent** | 11 MCP tools — check, replay, stamp, audit, embed, extract, detect, validate, scan, trust, create |
| **Any CLI tool** | `eval "$(akf shell-hook)"` — intercepts `claude`, `chatgpt`, `aider`, `openclaw`, `ollama`, `manus` |

**The trust pipeline:**
```
Agent writes code → Git commit stamped → CI runs akf certify → Team reviews with context
```

Set up in 60 seconds:
```bash
# 1. Agent stamps its own work (already in this repo)
cat CLAUDE.md        # or .cursorrules / .windsurfrules / AGENTS.md / .github/copilot-instructions.md

# 2. Git hooks stamp every commit
akf init --git-hooks

# 3. CI certifies trust on every PR
#    uses: HMAKT99/AKF/extensions/github-action@main

# 4. Shell hook intercepts AI CLI tools
eval "$(akf shell-hook)"
```

## Skills

AKF ships as a self-contained agent skill ([`skills/akf/`](skills/akf/SKILL.md)): the check-before-you-trust procedure, an evidence reference, and a read-only check script.

```bash
npx skills add HMAKT99/AKF          # Claude Code, Cursor, Copilot, Cline and 18+ agents
clawhub install akf                 # OpenClaw
hermes skills tap add HMAKT99/AKF   # Hermes Agent
```

## Format at a Glance

**Compact** (~15 tokens — optimized for AI):
```json
{"v":"1.0","claims":[{"c":"Revenue was $4.2B","t":0.98,"src":"SEC 10-Q"}]}
```

**Descriptive** (human-readable — same data):
```json
{"version":"1.0","claims":[{"content":"Revenue was $4.2B","confidence":0.98,"source":"SEC 10-Q"}]}
```

**Full** (with provenance, decay, AI flags, security):
```json
{"v":"1.0","by":"[email protected]","label":"confidential","inherit":true,
 "claims":[
   {"c":"Revenue $4.2B","t":0.98,"src":"SEC 10-Q","tier":1,"ver":true,"decay":90},
   {"c":"H2 will accelerate","t":0.63,"tier":5,"ai":true,"risk":"AI inference"}
 ],
 "prov":[
   {"hop":0,"by":"[email protected]","do":"created","at":"2025-07-15T09:30:00Z"},
   {"hop":1,"by":"copilot-agent","do":"enriched","at":"2025-07-15T10:15:00Z"}
 ]}
```

## Works With Every Format

AKF embeds natively — no sidecars needed for most formats:

| Format | How It Works |
|--------|-------------|
| `.akf` | Native standalone knowledge file |
| `.docx` `.xlsx` `.pptx` | OOXML custom XML part |
| `.pdf` | PDF metadata stream |
| `.html` | JSON-LD `<script type="application/akf+json">` |
| `.md` | YAML frontmatter |
| `.png` `.jpg` | EXIF/XMP metadata |
| `.json` | Reserved `_akf` key |
| `.mp4` `.mov` `.webm` `.mkv` | Sidecar `.akf.json` companion |
| `.mp3` `.wav` `.flac` `.ogg` | Sidecar `.akf.json` companion |
| Everything else | Sidecar `.akf.json` companion |

```python
# One API for all formats
akf.embed("report.docx", claims=[...], classification="confidential")
meta = akf.extract("report.docx")
akf.scan("report.docx")
```

## Zero-Touch Auto-Stamping

AKF can automatically stamp every file AI touches — no manual intervention needed.

```bash
# Install the background watcher
akf install

# Or run in foreground
akf watch ~/Downloads ~/Desktop ~/Documents
```

The background watcher monitors directories for new and modified files and stamps them with trust metadata. **Smart context detection** automatically infers:

- **Git author** — from `git log` history
- **Download source** — from macOS extended attributes
- **Classification** — from project `.akf/config.json` rules
- **AI-generated flag** — from LLM tracking timestamps + content heuristics
- **Confidence score** — dynamically adjusted based on available evidence

### Shell Hook (intercept AI CLI tools)

```bash
# Add to ~/.zshrc or ~/.bashrc
eval "$(akf shell-hook)"
```

Automatically detects when you run `claude`, `chatgpt`, `aider`, `openclaw`, `ollama`, or other AI CLI tools, and stamps any files they create or modify. Also pre-stamps files before upload to content platforms (`gws`, `box`, `m365`, `dbxcli`, `rclone`) so trust metadata travels with the file. Use `--no-upload-hooks` to disable.

### Project Rules

Create `.akf/config.json` in your project root:

```json
{
  "rules": [
    {"pattern": "*/finance/*", "classification": "confidential", "tier": 2},
    {"pattern": "*/public/*", "classification": "public", "tier": 3}
  ]
}
```

Files matching these patterns are automatically classified when stamped.

## Security Detections

10 built-in detection classes: AI content without review, trust below threshold, hallucination risk, knowledge laundering, classification downgrade, stale claims, ungrounded AI claims, trust degradation chain, excessive AI concentration, provenance gap.

```python
from akf import run_all_detections
report = run_all_detections(unit)
for finding in report.findings:
    print(f"[{finding.severity}] {finding.detection}: {finding.message}")
```

## Trust Computation

```
effective_trust = confidence × authority_weight × temporal_decay × (1 + penalty)
```

| Tier | Weight | Example |
|------|--------|---------|
| 1 | 1.00 | SEC filings, official records |
| 2 | 0.85 | Analyst reports, peer-reviewed |
| 3 | 0.70 | News, industry reports |
| 4 | 0.50 | Internal estimates, CRM data |
| 5 | 0.30 | AI inference, extrapolations |

**Decision:** score ≥ 0.7 → ACCEPT · ≥ 0.4 → LOW · < 0.4 → REJECT

**Delegation ceiling:** When an agent delegates to another, the delegate's output trust is capped at `min(score, delegation_ceiling)`. This prevents trust inflation in multi-agent chains.

## Compliance

**EU AI Act Article 50 takes effect August 2, 2026** — AI-generated content must carry transparency metadata (penalties up to EUR 35M / 7% of global turnover). Files stamped with AKF already carry it:

```bash
