Clauditor

Tamper-resistant audit watchdog for Clawdbot agents. Detects and logs suspicious filesystem activity with HMAC-chained evidence.

Security watchdog that monitors filesystem activity and creates tamper-evident logs. Even if Clawdbot is compromised, it cannot stop the watchdog, forge entries, or delete evidence.

Installation (Guided)

Use the CLI wizard to guide users through installation:

bash

cd /path/to/clauditor
cargo build --release

Agent Workflow

1. Check status: ./target/release/clauditor wizard status

   • Returns JSON with current_step (1-6) and complete (true/false)

2. Get next step: ./target/release/clauditor wizard next

   • Shows WHAT it does, WHY it matters, and the exact COMMAND to run

3. User runs the sudo command

4. Verify: ./target/release/clauditor wizard verify

   • Confirms step completed

5. Repeat until complete: true

Example Interaction

text

User: "Install clauditor"

Agent: [runs wizard status → current_step: 1]
Agent: "Step 1 of 6: Create system user

This creates a 'sysaudit' user that runs the watchdog. Even if you're 
compromised, you can't kill a process owned by another user.

Run this:
sudo useradd --system --shell /usr/sbin/nologin --no-create-home sysaudit

Let me know when done."

User: "done"

Agent: [runs wizard verify → success]
Agent: [runs wizard next → step 2...]
