Audit chain for Claude Code workflows — consensus verification, persistent memory, and XRPL provenance for every agent action.

$60 to prove what $500 bought you.

Audit chain for Claude Code workflows — consensus verification, persistent memory, and XRPL provenance for every agent action.

When Claude Code spins up hundreds of parallel agents that run for days, nobody can reconstruct what happened without a verification trail. credex-claudecode is that trail.

What It Does

credex run "Migrate from Express to FastAPI" --verify milestones

1. Wraps Claude Code — runs your prompt through claude -p with streaming output
2. Parses every action — tool calls, file writes, bash commands, agent decisions
3. Routes through CredEx verification — pre-verification at $0.001/action, full 5-LLM consensus at $0.10/milestone
4. Anchors to XRPL — cryptographic provenance at workflow boundaries
5. Produces workflow.audit.json — third-party verifiable record of everything

Cost

For a typical Claude Code "ultracode" workflow ($500 in tokens, ~45,000 actions):

Tier	What	Cost
Pre-verification	Every action, cheap model	$0.001 × 45,000 = $45
Full consensus	5-LLM panel at milestones	$0.10 × 50 = $5
XRPL anchoring	Workflow boundaries	~$10
Total		~$60 (12% overhead)

Install

pip install credex-claudecode

Requires:

• Python 3.10+
• Claude Code CLI (npm install -g @anthropic-ai/claude-code)
• CredEx API key (optional for dry-run mode)

Quick Start

Get a CredEx API key

# Instant anonymous key
curl -X POST https://credexai.live/agent/auth -d '{"type":"anonymous"}'

# Set it
export CREDEX_API_KEY=credex_...

Run a workflow with audit chain

# Full audit (milestones verified + XRPL anchored)
credex run "Migrate the auth module from Express to FastAPI"

# Verify everything (costs more, thorough)
credex run "Security audit of the payment module" --verify all

# Dry run (no CredEx, local audit only)
credex run "Rewrite tests in pytest" --dry-run

# Pass Claude Code options
credex run "Fix the bug in auth.py" --allowed-tools "Read,Edit,Bash" --model claude-sonnet-4-20250514

Inspect an audit

# Pretty-print summary
credex audit workflow.audit.json

# Verify chain integrity
credex audit workflow.audit.json --verify

Lightweight hooks (no wrapper needed)

# Install PostToolUse hooks into your project
credex install-hooks

# Now every Claude Code session automatically logs to CredEx
claude  # Use normally — CredEx logging happens in background

workflow.audit.json

The audit file is a self-contained, third-party verifiable record:

    "final_hash": "d8e9...",

  }
}

Verification: Each action's chain_hash = SHA256(prev_hash + content_hash + sequence). Recompute from genesis to verify the entire chain.

Integration Paths

1. CLI Wrapper (Full Audit)

Use credex run for complete audit chains. Best for high-stakes workflows: migrations, security audits, rewrites.

2. PostToolUse Hooks (Lightweight)

Use credex install-hooks for background logging. Best for everyday use — zero friction, events stored in CredEx memory.

3. Python SDK (Programmatic)

from credex_claudecode.parser import StreamEventParser
from credex_claudecode.verifier import CredExVerifier

parser = StreamEventParser(prompt="my workflow")
verifier = CredExVerifier(api_key="credex_...", verify_level="milestones")

# Parse events from any source
for line in event_stream:
    actions = parser.parse_line(line)
    for action in actions:
        result = await verifier.process_action(action)

session = parser.finalize()

Why This Matters

Claude Code "ultracode" workflows spin up ~200 parallel agents, execute ~45,000 actions, and run for days. When that $500 workflow completes:

• Without CredEx: You have code changes. You don't know what decisions were made, what was tried and failed, or what was verified vs. guessed.
• With CredEx: You have a cryptographic audit chain. Every action verified, every decision anchored, every workflow reconstructable.

For enterprise teams running Claude Code on production codebases, the audit chain isn't optional — it's the difference between "we think the migration worked" and "here's the proof."
