ClawDNA: A Three-Skill DNA Management System for AI Agent Configuration Reproduction and Genetic Recombination

Abstract

We present ClawDNA, a complete lifecycle management system for AI agent configurations inspired by biological DNA. The system comprises three coordinated skills: (1) clawdna-generator extracts a machine-specific DNA document with hardware-anchored fingerprinting and automatic sensitive field anonymization; (2) clawclone installs a complete OpenClaw instance from a DNA document through an interactive wizard with merge/replace modes; (3) clawreprodu combines two parent DNAs through randomized genetic recombination, producing hybrid offspring with full lineage tracing. The core innovation is the biological metaphor applied to AI agent configuration: agents inherit traits (agents, providers, skills, channels) from parent configurations via locus-based random selection, with automatic dependency repair ensuring installability. This transforms AI agent deployment from manual reconstruction into a reproducible, evolutionary process. Five chromosomes are defined: infrastructure, providers, agents, skills, and channels. A working implementation demonstrates the complete workflow from a coding-focused agent to a hybrid finance-coding configuration.

1. Introduction

AI agent deployments are becoming increasingly complex. A production OpenClaw instance typically includes 10+ sub-agents, multiple model providers, 30+ skills, and several communication channels. When setting up a new machine or reproducing a working configuration, operators face a tedious manual reconstruction process: copying configuration files, reinstalling skills, configuring API keys, and verifying dependencies.

Meanwhile, biological systems solved this problem billions of years ago through DNA. Every cell in your body contains the same DNA, and reproduction combines genetic material from two parents through recombination—creating offspring that are neither exact copies nor completely novel, but combinations of parental traits.

The core insight: AI agent configurations can be treated as "genetic material" that can be extracted, stored, reproduced, and recombined.

ClawDNA implements this metaphor as a three-skill system. A DNA document captures an agent instance's complete configuration (agents, providers, skills, channels). The DNA can be installed on a new machine (cloning) or recombined with another DNA to produce a hybrid offspring (reproduction). The result is a new configuration carrying traits from its parents.

2. System Architecture

2.1 The Three-Skill Lifecycle

   Extract DNA            Install DNA            Produce Hybrid
   to .yaml file         to new machine          DNA offspring

clawdna-generator extracts a DNA document from a running OpenClaw instance:

  • Captures L0 (gateway, providers) and L1 (agents, skills, channels, workspace)
  • Generates hardware-anchored fingerprint (UUID + SHA256 content hash)
  • Automatically replaces sensitive values (API keys, tokens) with {{PLACEHOLDER}} tags
  • Output: portable YAML file safe for sharing

clawclone installs a DNA document to a target machine:

  • Interactive wizard guides user through filling placeholder values
  • Supports two modes: merge (preserve existing agents not in DNA) or replace (full overwrite)
  • Dependency scanner checks for missing skills and providers before installation
  • Validates DNA schema before writing files

clawreprodu combines two parent DNAs:

  • Random locus-based recombination (each gene randomly inherits from Parent A or B)
  • User-specified mixing ratio (e.g., 60% A / 40% B)
  • Orphan gene handling: genes present in only one parent are randomly included/excluded
  • Automatic dependency repair: two-pass validation ensures all required skills/providers exist

2.2 The Five Chromosomes

Chromosome Contents Recombination Unit
infrastructure Gateway config, runtime settings Per-locus
providers Model provider configurations Per-provider-id
agents Agent definitions (SOUL.md, models.json) Per-agent-id
skills Bundled allowed + custom skills Per-skill
channels Messaging channel configurations Per-channel

Each chromosome is independently recombined, allowing fine-grained trait inheritance.

3. Key Technical Contributions

3.1 Hardware-Anchored Fingerprinting

The DNA fingerprint combines:

  • id: unique identifier (e.g., deepeye-main-agent-a17fffc4-b5c4d3e2)
  • source_hardware.hostname: machine name
  • source_hardware.hw_uuid: hardware UUID (provides physical uniqueness)
  • content_hash: SHA256 of the full DNA content (enables integrity verification)

The hardware UUID ensures that two DNA files with the same agent name remain distinguishable if extracted from different machines.

3.2 Automatic Sensitive Field Anonymization

During DNA extraction, all sensitive values are replaced with {{CATEGORY_IDENTIFIER}} placeholders:

  • {{ENV_*}} — Environment variables (API keys for external services)
  • {{PROVIDER_*}} — Model provider credentials
  • {{CHANNEL_*}} — Messaging channel tokens and user IDs

The resulting DNA file is safe to share publicly. During installation, clawclone prompts the user to fill in actual values.

3.3 Locus-Based Genetic Recombination

The recombination algorithm treats each configuration element as a genetic "locus":

For each locus (agent/provider/skill/channel):
  - If present in both parents: randomly pick from A (ratio_a) or B (1-ratio_a)
  - If only in A: include with probability = ratio_a (orphan A)
  - If only in B: include with probability = 1 - ratio_a (orphan B)

3.4 Two-Pass Dependency Repair

After recombination, automatic dependency repair ensures installability:

Round 1: For each agent in the offspring, verify all required skills exist in the skills chromosome. If missing, add from the parent that has it.

Round 2: For each agent's model configuration, verify all referenced providers exist in the providers chromosome. If missing, add from the parent that has it.

This guarantees that any DNA produced by clawreprodu can be installed by clawclone without manual intervention.

3.5 Full Lineage Tracing

The offspring DNA records both parents in its fingerprint:

lineage:
  parents:
    - id: deepeye-main-agent-a17fffc4-b5c4d3e2
      hw_uuid_segment: A17FFFC4-6378-58A9
    - id: serverb-assistant-c4f2e1d0-9d8e7f6a
      hw_uuid_segment: C4F2E1D0-9D8E-7F6A

This enables complete ancestry tracking—a hybrid configuration can be traced back to its original sources.

4. Use Cases

4.1 Reproducing a Production Configuration

A developer maintains a production OpenClaw instance. Before experimenting with changes, they extract a DNA:

clawdna-generator → production-v1.dna.yaml

After experiments fail, they reinstall the production DNA:

clawclone → production-v1.dna.yaml

4.2 Creating a Hybrid Configuration

An organization runs two specialized agents:

  • Agent A: coding-focused (architect, backend, frontend, qa, devops)
  • Agent B: finance-focused (wealth-cio, wealth-researcher, wealth-trader)

They want to combine capabilities. Using clawreprodu with a 50:50 ratio:

clawreprodu agent-a.dna.yaml agent-b.dna.yaml 0.5 → hybrid.dna.yaml

The offspring inherits some agents from each parent, potentially discovering emergent capabilities not present in either parent.

4.3 Lineage-Based Debugging

When a hybrid configuration exhibits unexpected behavior, the lineage tracing allows operators to trace which genes came from which parent, enabling targeted debugging.

        elif in_a:
            # Orphan A: include with probability = ratio_a
            if random.random() < ratio_a:

            if random.random() < (1 - ratio_a):
                offspring[agent_id] = dna_b.agents[agent_id]
    
    # (Similar logic for providers, skills, channels)
    
    # Dependency repair passes
    offspring = repair_dependencies(offspring)
    
    return offspring

6. Related Work

Configuration management in AI agent systems remains primarily a manual process. Existing tools focus on single-machine provisioning (Ansible, Docker) or version control (Git for config files), but none propose a genetic recombination model for configuration evolution.

The biological metaphor has been applied to software in genetic algorithms and evolutionary computation, but typically at the algorithmic level (evolving neural network weights, optimization parameters). ClawDNA applies the metaphor to the structural level—evolving the configuration itself.

7. Conclusion

ClawDNA transforms AI agent configuration from static files into a dynamic, evolutionary system. By extracting configurations as DNA, cloning them across machines, and recombining them through genetic algorithms, operators gain reproducibility, portability, and the potential for emergent hybrid capabilities.

The three-skill lifecycle—sequence, clone, reproduce—mirrors biological reproduction at the configuration level. As AI agent systems grow more complex, such systematic approaches to configuration management will become essential.

Key contributions:

  1. A complete DNA extraction system with hardware anchoring and sensitive field anonymization
  2. An interactive installation wizard with merge/replace modes
  3. A genetic recombination engine with locus-based inheritance and dependency repair
  4. Full lineage tracing for ancestry tracking

The system is implemented as three OpenClaw skills and is available for installation.

description: Extract a DNA document from the current openclaw instance. Captures L0 (gateway, providers) and L1 (agents, skills, channels, workspace identity) into a portable YAML file with a unique hardware-anchored fingerprint.
---

# ClawDNA Generator

Extracts the current openclaw instance's core characteristics into a portable DNA document. The DNA encodes the instance's agent team, model routing, skills, channel integrations, and workspace identity — everything needed to reproduce or combine this instance elsewhere.

The fingerprint in the generated DNA is anchored to the physical hardware's UUID, ensuring uniqueness even if two instances share the same agent name.

## When to use

Run this skill when you want to:
- Archive the current state of this openclaw instance
- Prepare a DNA for cloning onto another machine (`clawclone`)
- Prepare a parent DNA for genetic recombination (`clawreprodu`)

## Prerequisites

The following tools must be installed: `jq`, `yq`

Check with:
```bash
which jq yq
```

If missing on macOS: `brew install jq yq`
If missing on Linux: `apt install jq` + [yq install guide](https://github.com/mikefarah/yq#install)

## Workflow

**Step 1 — Ask the user for a DNA name**

Prompt: "Please provide a short name for this DNA snapshot (e.g. `macmini-main`, `deepeye-v2`). This will be used as the filename prefix."

- Name should be alphanumeric + hyphens only
- No spaces, no special characters

**Step 2 — Run extraction**

Determine the absolute path to the clawdna project scripts directory. The script is at:
`<clawdna_project_root>/scripts/extract.sh`

Run:
```bash
bash <clawdna_project_root>/scripts/extract.sh <dna_name> 2>/tmp/clawdna-extract-err.log
```

Capture stdout. If the exit code is non-zero, read `/tmp/clawdna-extract-err.log` and report the error to the user.

**Step 3 — Parse output**

From stdout:
- Lines matching `^\{\{[A-Z0-9_]+\}\}$` are placeholder keys
- The last line starting with `OUTPUT_PATH:` contains the output file path

Parse the output file path:
```bash
OUTPUT_PATH=$(grep '^OUTPUT_PATH:' <stdout> | cut -d: -f2-)
```

**Step 4 — Read the fingerprint**

Read the fingerprint ID from the generated DNA file:
```bash
yq -r '.fingerprint.id' "$OUTPUT_PATH"
yq -r '.fingerprint.source_hardware.hostname' "$OUTPUT_PATH"
yq -r '.fingerprint.source_hardware.hw_uuid' "$OUTPUT_PATH"
```

**Step 5 — Report to user**

Show the user:
1. The fingerprint ID (e.g. `deepeye-main-agent-a17fffc4-b5c4d3e2`)
2. The source hardware: hostname + hw_uuid prefix
3. The list of placeholder keys (the sensitive values that were anonymized)
4. The DNA file path

Example output:
```
✓ DNA extracted successfully

Fingerprint: deepeye-main-agent-a17fffc4-b5c4d3e2
  Primary index : DeepEye Main Agent
  Hardware UUID : A17FFFC4-6378-58A9-A94C-9BC312C71F33
  Host          : macmini

Anonymized placeholders (24 total):
  {{ENV_BRAVE_API_KEY}}
  {{PROVIDER_LOVBROWSER_API_KEY}}
  {{CHANNEL_TELEGRAM_BOT_TOKEN}}
  ... (full list)

DNA saved to: ~/.openclaw/dna/macmini-main-20260317.dna.yaml

Use clawclone to install this DNA on another machine.
Use clawreprodu to combine it with another DNA.
```

## Notes

- The DNA does **not** contain session history, delivery queue, or logs
- Sensitive values (API keys, tokens, secrets) are replaced with `{{PLACEHOLDER}}` — the DNA is safe to share
- The `content_hash` field in the fingerprint is a SHA256 of the full DNA content, allowing integrity verification
- To verify integrity later: `shasum -a 256 <dna_file>` should match `fingerprint.content_hash` (after setting that field to "pending")

# CLAWCLONE


---
name: clawclone
description: Install an openclaw instance from a DNA document. Guides the user through filling placeholder values, dependency checks, and installation onto the current machine. Supports merge (agent-level) or full-replace modes.
---

# ClawClone

Installs a complete openclaw instance from a DNA document. The DNA may come from `clawdna-generator` (direct clone) or `clawreprodu` (hybrid). The install wizard guides you through filling in all anonymized placeholders (API keys, tokens, etc.) before writing any files.

## When to use

- Setting up openclaw on a new machine using an existing DNA
- Reproducing a tested agent configuration from a DNA snapshot
- Installing a hybrid DNA generated by `clawreprodu`

## Prerequisites

Required tools: `yq`, `jq`
Optional (recommended): `check-jsonschema` — validates DNA format before install

```bash
# Install check-jsonschema (Python)
pip install check-jsonschema
```

## Workflow

**Step 1 — List available DNA files**

```bash
ls -1t ~/.openclaw/dna/*.dna.yaml 2>/dev/null
```

For each DNA file, show the fingerprint summary:
```bash
yq -r '"  ID     : " + .fingerprint.id + "\n  Agent  : " + .fingerprint.primary_index + "\n  Host   : " + .fingerprint.source_hardware.hostname + "\n  HW UUID: " + .fingerprint.source_hardware.hw_uuid + "\n  Date   : " + .fingerprint.generated_at' <dna_file>
```

Ask the user to select which DNA to install.

**Step 2 — Conflict check**

Check if `~/.openclaw/openclaw.json` already exists:
```bash
[ -f ~/.openclaw/openclaw.json ] && echo "EXISTS" || echo "FRESH"
```

If EXISTS, ask the user:
> An existing openclaw.json was found. How would you like to proceed?
> - **merge**: DNA agents overwrite same-ID agents; existing agents not in DNA are kept. Other fields (gateway, providers, channels) are replaced by the DNA.
> - **replace**: Current openclaw.json is backed up first (with timestamp), then fully replaced by the DNA.
> - **cancel**: Abort installation.

Record the chosen mode (`merge` or `replace`).

If FRESH, use `replace` mode automatically.

**Step 3 — Dependency check**

Run the scanner to see what placeholders need filling:
```bash
bash <clawdna_project_root>/scripts/clone.sh --scan <selected_dna_file>
```

Also check:
1. For any `custom` skills with `type: reference` — verify that `source` URLs are accessible
2. If any provider has `id: local` or `baseUrl` containing `localhost:11434` — check if Ollama is installed:
   ```bash
   which ollama && ollama list
   ```
   If Ollama is missing, inform the user: "This DNA requires a local Ollama instance. Install from https://ollama.ai before proceeding."

**Step 4 — Fill placeholders interactively**

Display the placeholder list grouped by category:
- `{{ENV_*}}` — Environment variables (API keys for external services)
- `{{PROVIDER_*}}` — Model provider credentials
- `{{CHANNEL_*}}` — Messaging channel tokens and user IDs

For each placeholder:
- Show the placeholder key
- Ask the user for the actual value
- If the user wants to skip, keep the `{{KEY}}` string (will remain unfilled with a warning)

Write collected values to a temporary YAML file at `/tmp/clawclone-values.yaml`:
```yaml
placeholders:
  ENV_BRAVE_API_KEY: "actual-value-here"
  PROVIDER_LOVBROWSER_API_KEY: "actual-key"
  CHANNEL_TELEGRAM_BOT_TOKEN: "123456:ABC..."
```

**Step 5 — Install**

Run the install script:
```bash
bash <clawdna_project_root>/scripts/clone.sh \
  --install <selected_dna_file> /tmp/clawclone-values.yaml \
  --mode <merge|replace>
```

If exit code is non-zero, report the error. Do not retry automatically — ask the user how to proceed.

**Step 6 — Show installation summary**

Parse and display the summary from stdout:
- Source fingerprint ID and origin host
- Install mode used
- Number of agents installed
- Number of skills installed
- Any unfilled placeholder warnings

Example:
```
✓ ClawDNA Clone Complete

Source fingerprint : deepeye-main-agent-a17fffc4-b5c4d3e2
Source host        : macmini (A17FFFC4-6378-58A9-A94C-9BC312C71F33)
Install mode       : replace (backup saved)
Agents installed   : 13
Skills installed   : 5

⚠ 2 placeholder(s) were not filled and remain in openclaw.json:
  {{CHANNEL_FEISHU_BOT3_APP_SECRET}}
  {{PROVIDER_KIMI_CODING_API_KEY}}
  → Edit ~/.openclaw/openclaw.json to fill these before starting the gateway.

Next step: restart the openclaw gateway to activate the new configuration.
```

## Notes

- The `/tmp/clawclone-values.yaml` file is deleted automatically after install
- The SOUL.md files for each agent are written to `~/.openclaw/agents/<agent_id>/workspace/SOUL.md`
- Main workspace soul and memory digest are written to `~/.openclaw/workspace/`
- Embedded custom skills are installed to `~/.openclaw/skills/<skill_name>/SKILL.md`
- The backup file (replace mode) is named `openclaw.json.backup.YYYYMMDDHHMMSS`

# CLAWREPRODU


---
name: clawreprodu
description: Combine two DNA documents through randomized genetic recombination, producing a new hybrid DNA that inherits traits from both parents. Each gene locus (agent, provider, skill, channel) is randomly assigned to come from Parent A or Parent B based on a user-specified mixing ratio.
---

# ClawReprodu

Creates a new openclaw DNA through genetic recombination of two parent DNAs. Like biological sexual reproduction, each gene locus is randomly assigned from one parent or the other. The result is a new entity that is neither parent A nor B, but carries traits from both.

**Orphan genes** (loci present in only one parent) are randomly included or excluded based on the mixing ratio. **Dependency repair** ensures the resulting DNA is always installable — missing skills and providers are automatically patched.

The new DNA carries its own unique fingerprint anchored to the hardware where `clawreprodu` runs, with full lineage tracing both parent IDs.

## When to use

- Combining a coding-focused instance with a finance-focused instance
- Creating experimental hybrid agent configurations
- Exploring emergent capabilities from two evolved lineages

## Prerequisites

Required: `yq`, `jq`, `awk`

## Workflow

**Step 1 — List and select parent DNAs**

```bash
ls -1t ~/.openclaw/dna/*.dna.yaml 2>/dev/null
```

For each file, show:
```bash
yq -r '"[" + .fingerprint.id + "]  " + .fingerprint.primary_index + "  (" + .fingerprint.source_hardware.hostname + ")"' <dna_file>
```

Ask the user to select:
- **Parent A (dominant)**: the DNA whose traits are more likely to appear
- **Parent B (recessive)**: the DNA whose traits appear less frequently

A and B can be the same file (self-recombination — produces variation within a single lineage).

**Step 2 — Show chromosome summaries**

For each selected DNA, display:
```bash
echo "=== Parent A: $(yq -r '.fingerprint.id' "$DNA_A") ==="
echo "  Agents   : $(yq -r '.agents | keys | length' "$DNA_A")"
echo "  Providers: $(yq -r '.providers | length' "$DNA_A")"
echo "  Skills   : $(yq -r '.skills.bundled_allowed | length' "$DNA_A") bundled + $(yq -r '.skills.custom | length' "$DNA_A") custom"
echo "  Channels : $(yq -r '.channels | keys | join(", ")' "$DNA_A")"
```

Show the same for Parent B.

Show a table of agent IDs present in each:

| Agent ID | In A | In B |
|----------|------|------|
| main     | ✓   | ✓   |
| architect| ✓   | ✗   |
| ...      | ...  | ...  |

**Step 3 — Ask for mixing ratio**

Prompt:
> What mixing ratio do you want? Enter as A:B (e.g. `6:4` means 60% chance of inheriting from A at each locus).
> Default is `5:5` (equal probability).

Parse to `ratio_a` float (e.g. `6:4` → `0.6`):
```bash
# If user enters "6:4":
ratio_a=$(echo "6:4" | awk -F: '{printf "%.4f", $1/($1+$2)}')
# Result: 0.6000
```

**Step 4 — Run recombination**

```bash
bash <clawdna_project_root>/scripts/reprodu.sh \
  <dna_a_path> <dna_b_path> <ratio_a> \
  2>/tmp/clawdna-reprodu-err.log
```

Capture stdout. If exit code is non-zero, read the error log and report to user.

**Step 5 — Parse and display the recombination report**

From stdout:
- Parse the section between `═══ ClawDNA Reproduction Report ═══` and `═══════`
- Display the full report to the user
- Extract `OUTPUT_PATH:` line for the new DNA file path

Example display:
```
✓ Recombination complete

New fingerprint: reprodu-a17fffc4-9f3e7a1c
  Parent A: deepeye-main-agent-a17fffc4-b5c4d3e2 (DeepEye Main Agent)
  Parent B: serverb-assistant-c4f2e1d0-9d8e7f6a  (ServerB Assistant)
  Ratio   : 60% A / 40% B

Agents inherited: 9
  agents.main      : from A
  agents.architect : from A
  agents.frontend  : from B (orphan B, inherited)
  agents.qa        : from B
  agents.devops    : SKIP (orphan A, rejected by random)
  agents.wealth-cio: from A

Dependency repair:
  auto-repair: added provider 'kimi-coding' from B (required by agent frontend)

New DNA saved to: ~/.openclaw/dna/reprodu-20260317143022.dna.yaml
```

**Step 6 — Offer to proceed with installation**

Ask the user:
> The new DNA is ready. Would you like to install it now using clawclone?
> - **Yes**: proceed with clawclone workflow on the new DNA
> - **No**: the DNA is saved and can be installed later with the `clawclone` skill

If yes, invoke the `clawclone` skill with the new DNA file path as context.

## Recombination rules reference

| Locus situation | Inheritance rule |
|-----------------|-----------------|
| Present in both A and B | Randomly pick A (ratio_a) or B (1-ratio_a) |
| Only in A (orphan) | Include with probability = ratio_a |
| Only in B (orphan) | Include with probability = 1 - ratio_a |
| Neither (impossible) | N/A |
| Result: empty agents | Force-include highest-probability orphan agent |
| Result: empty providers | Force-include highest-probability orphan provider |

Chromosomes recombined independently:
1. `infrastructure` — selected as a unit (A or B)
2. `providers` — per-provider-id locus recombination
3. `agents` — per-agent-id locus recombination
4. `skills.bundled_allowed` — per-skill union recombination
5. `skills.custom` — per-skill-name locus recombination
6. `channels` — selected as a unit (A or B)
7. `workspace` — selected as a unit (A or B)

After recombination, two dependency repair passes run automatically:
- **Round 1**: ensures all agent skills exist in the skills chromosome
- **Round 2**: ensures all agent model providers exist in the providers chromosome

## Notes

- Each run of `clawreprodu` produces a different result (true random seed)
- To reproduce a specific combination, save and reuse the output DNA file
- The new DNA still contains `{{PLACEHOLDER}}` values inherited from parents — use `clawclone` to fill them in during installation
- `lineage.parents` in the fingerprint records both parent IDs with their hardware UUID segments, enabling full ancestry tracing
