coc-soul — agent identity, backup, and resurrection

The soul layer for AI agents: on-chain DID, encrypted backups to IPFS, social recovery via guardians, and cross-device resurrection via carriers. Backed by the npm package @chainofclaw/soul which ships both a standalone coc-soul CLI and an OpenClaw skill (id coc-soul).

Soul works standalone (backs up the agent's home tree to chain + IPFS), and gets one extra capability when claw-mem2db is installed alongside it: each backup also captures claw-mem's chat history, tool-call observations, and session summaries as a token-budgeted semantic snapshot. Recover on a fresh host and the agent gets back not just its files but its remembered context — chat preferences, decisions, conversation history. This is the "digital / silicon-based persistence" story.

30-second decision tree (operators read here first)

If the user is asking "how do I recover on another machine?", pick one path before saying anything else:

1. Have backup material (manifest CID or ~/.openclaw/.coc-backup/latest-recovery.json) → use the restore path: openclaw coc-soul backup restore ...
2. Lost the owner key OR need to migrate ownership → use resurrection (owner-key) or guardian social recovery

Don't merge the two explanations until the path is selected. recovery and resurrection are different flows (see references/guardian-recovery.md).

Critical CID terminology (avoid confusion)

Rule: when a user asks "what's your CID?", first confirm whether they mean the latest backup manifest CID vs. an older backup CID vs. the identity registration CID — they get conflated constantly.

Key material — agent safety rules

Hard rule for any agent reading this skill: never request, transmit, or echo private keys in chat — including "split" or "encrypted" fragments. Always route key transfer to a local secure channel.

Ultra-quick runbook (10 lines)

1. Pick the path first: restore or resurrection (see the decision tree above).
2. Run openclaw coc-soul backup doctor --json and read chain.registered / restore.available / resurrection.configured.
3. If there's a manifest CID or a latest-recovery.json, take the restore path.
4. Restore to /tmp/... first — never overwrite a production directory in one step.
5. Verify merkleVerified: true + exit code 0, then promote to the production path only after explicit user confirmation.
6. No owner key but resurrection was pre-configured → take the resurrection flow.
7. Need multi-party approval for ownership migration → take guardian recovery (quorum + timelock).
8. Script the heartbeat first, then schedule it via cron / systemd / OpenClaw scheduler.
9. Private keys never go through chat (including split / encrypted fragments or temporary paste).
10. Default command surface is openclaw coc-soul ...; the bare coc-soul ... only exists when the standalone bin was installed via npm i -g @chainofclaw/soul.

Common failure → cause → fix

Full per-command troubleshooting lives at the end of references/backup.md and references/config.md.

Cross-host restore — read BEFORE you blanket-overwrite (1.2.4+)

The most dangerous restore scenario: backup made on host A (e.g. $HOME=/home/node), restoring on host B ($HOME=/home/baominghao). The backup's files contain absolute paths to host A; literal copies will (a) fake history, (b) corrupt SQLite if anyone tries byte-level sed, and (c) wipe out host B's gateway.auth configuration, locking the operator out with a 1008 right after restart.

The agent must ask the user before any cross-host restore. Don't auto-overwrite. Three-class policy:

Auth-mode warning, in particular: gateway.auth.mode and .token / .password belong to the host, not the agent. After restoring, always re-check:

jq '.gateway.auth.mode' ~/.openclaw/openclaw.json

Pick the matching TUI flag — --token only works when mode = "token" AND .token is non-null. If the active mode is password or trusted-proxy, jq -r .gateway.auth.token returns the literal string "null" and TUI sends that, which the gateway rejects with 1008. Don't reflexively use --token after a restore — read the active mode first.

Full procedure with command-line examples: references/backup.md → "Cross-host restore: directory-mismatch handling" + "Auth-mode preservation rule".

Post-backup messaging contract (1.2.6+)

After every successful backup create, the agent MUST relay the recovery info to the user. The CLI 1.2.6+ prints it; agents that wrap the CLI must pass it through, not swallow it. The user needs four things to be able to restore later:

1. The manifest CID (b.manifestCid, e.g. bafy...) — what to ask for at restore time.
2. The signing-key location — where the private key needed to read the encrypted backup lives. One of:
   • ~/.claw-mem/keys/agent.key (default keystore, mode 0600, auto-generated when backup.privateKey is unset; resolution chain: $COC_SOUL_KEYSTORE_PATH → $OPENCLAW_STATE_DIR/coc-soul/keys/agent.key → ~/.claw-mem/keys/agent.key)
   • backup.privateKey in ~/.openclaw/openclaw.json (when operator set it explicitly)
3. The encryption mode — none / privateKey / password — determines whether --password is needed at restore time.
4. The recovery package path — \x3CsourceDir>/.coc-backup/latest-recovery.json — small JSON file with all of the above pre-formatted; copy this off-host alongside the key for fast restore.

The CLI emits this block:

Backup complete (full):
  manifest:   bafyabc...
  files:      127
  bytes:      4194304
  merkleRoot: 0xabc...
  txHash:     0xdef...

Recovery info — keep this safe to restore on another host:
  recovery package: /home/\x3Cuser>/.openclaw/.coc-backup/latest-recovery.json
  encryption mode:  privateKey
  signing key file: /home/\x3Cuser>/.claw-mem/keys/agent.key (mode 0600 — copy off-host securely)
  signer address:   0x...

To restore on another host (always restore to /tmp first, verify, then promote):
  openclaw coc-soul backup restore --manifest-cid bafyabc... \
    --target-dir /tmp/openclaw-restore-test

  (if you also have /home/\x3Cuser>/.openclaw/.coc-backup/latest-recovery.json on the target host:)
  openclaw coc-soul backup restore --latest-local --target-dir /tmp/openclaw-restore-test

Agent responsibilities when displaying this:

• Echo the manifest CID verbatim (it's how the user later asks "restore my backup bafy...")
• Echo the signing key file path verbatim — this is the file the user must back up off-host (encrypted USB / passphrase-protected vault / hardware security module). Do NOT print the key contents themselves.
• Echo the To restore on another host block verbatim — operators on the recovery host will copy-paste it
• If the encryption mode is password, remind the user that --password '\x3Cvalue>' is required at restore time and they must remember it (or store it securely separately)

For agents running headless (no user attention right now): the same info is persisted to ~/.openclaw/.coc-backup/latest-recovery.json automatically — operators can read it later via cat or openclaw coc-soul backup status --json.

Relationship with claw-mem2db

claw-mem and coc-soul are separate, decoupled skills. Each works on its own; together they cover complementary halves of "agent persistence":

Detection is automatic and silent. At plugin activation, soul probes the same dataDir chain claw-mem uses ($CLAW_MEM_DATA_DIR → $OPENCLAW_STATE_DIR/claw-mem → ~/.claw-mem) and logs one of two lines:

• [coc-soul] claw-mem detected at \x3Cpath> — semantic snapshot ... will be included in each backup
• [coc-soul] claw-mem not detected — backups will skip the semantic snapshot (install @chainofclaw/claw-mem alongside soul to enable memory replay on recovery)

No coupling at the npm-dependency level: soul does not depend on the @chainofclaw/claw-mem package. It just opens the SQLite DB read-only when present and reads two tables (observations, session_summaries). If the DB schema is absent or unreadable, soul logs a warning and moves on — backup never fails because of a memory hiccup.

Data dir alignment with claw-mem (1.2.0+)

Soul writes its own files (keystore, config.json) to the same root as claw-mem by default — ~/.claw-mem — so the two plugins share one operator-managed directory. Resolution priority (matches claw-mem's chain):

1. plugins.entries.coc-soul.config.backup.dataDir (per-instance plugin config, when set)
2. $CLAW_MEM_DATA_DIR (shared with claw-mem)
3. $OPENCLAW_STATE_DIR/coc-soul (sandboxed-host fallback, soul-specific subdir)
4. ~/.claw-mem (default)
5. ~/.openclaw/state/coc-soul (1.2.2+ auto-fallback when the default is owned by the wrong uid — typical multi-user Docker host)

If none of these are writable, soul fails fast at activation with a copy-paste-ready EACCES message (each candidate path, the resolved getuid() + HOME, and a one-line fix). No silent /tmp fallback. No half-broken backup runs.

Mental model

Every AI agent is identified by a bytes32 agentId, controlled by an EOA (owner). The skill covers five concerns:

Zero-config on COC testnet (1.1.6+)

Out of the box, no setup is required to run against COC testnet. A fresh openclaw plugins install @chainofclaw/soul lands an agent that can immediately query the chain, register a soul, and run backups. Specifically, on first activation the plugin:

1. Auto-generates an agent EOA if backup.privateKey is empty. The key file is written with mode 0o600 to one of (in priority order):

   • $COC_SOUL_KEYSTORE_PATH (operator override)
   • $OPENCLAW_STATE_DIR/coc-soul/keys/agent.key (set by OpenClaw inside its sandbox — the typical path)
   • ~/.claw-mem/keys/agent.key (standalone default)

   The chosen path and resulting agent address are logged: [coc-soul] auto-generated agent key at \x3Cpath> and [coc-soul] agent address: 0x….

2. Auto-drips testnet COC to the new EOA from the public faucet (backup.faucetUrl defaults to http://199.192.16.79:3003, 10 COC per drip, 24h per-address cooldown). Logs: [coc-soul] faucet dripped 10.0 COC to 0x… (tx 0x…). So the very first openclaw coc-soul backup init already has gas.

3. Defaults rpcUrl, ipfsUrl, contractAddress, didRegistryAddress to the live COC testnet (RPC 199.192.16.79:28780, IPFS 199.192.16.79:28786, deployed SoulRegistry / DIDRegistry).

You do NOT need to set any of these manually for testnet usage. The agent should openclaw coc-soul backup init directly. Override fields only when targeting mainnet, a private testnet, or an existing wallet.

To bypass the keystore (e.g. use a wallet you already have): set backup.privateKey in config. To disable the auto-faucet (mainnet): set backup.faucetUrl: "".

How to invoke

Inside OpenClaw (recommended — works automatically after plugins install):

openclaw coc-soul backup status
openclaw coc-soul did delegations --agent-id 0x...

Standalone bin (only if you ran npm i -g @chainofclaw/soul separately):

coc-soul backup status

openclaw plugins install does NOT install the standalone coc-soul binary into your PATH. Use openclaw coc-soul ... (with the openclaw prefix), or install the bin globally via npm if you want the bare command.

Typical flows

1. First-time soul registration + backup (zero config) — Just run openclaw coc-soul backup init. The plugin auto-generates the agent EOA, auto-drips testnet COC for gas, then registers on SoulRegistry and runs the first full backup. No manual privateKey, no manual faucet, no manual contract addresses. Watch the activation logs to see the chosen keystore path and the agent address.
2. Periodic incremental backup — openclaw coc-soul backup create (auto runs hourly if backup.autoBackup: true).
3. Inspect agent state — openclaw coc-soul backup status (summary), openclaw coc-soul backup doctor (actionable recommendations).
4. Delegation — openclaw coc-soul did delegate --delegator \x3CagentId> --delegatee \x3CtargetId> --scope \x3Chash> --expires \x3Cepoch> --depth 0.
5. Guardian setup — openclaw coc-soul guardian add --agent-id \x3Cid> --guardian 0x... (repeat for each guardian).
6. Emergency recovery (you lost your owner key) — a guardian runs openclaw coc-soul recovery initiate, the quorum approves via recovery approve, then after timelock recovery complete.
7. Resurrection as carrier — openclaw coc-soul carrier register --endpoint https://... on the hosting node; openclaw coc-soul carrier start runs the daemon.

When NOT to use this skill

• Running a COC chain node yourself — use coc-node.
• Local semantic memory only (no chain backup needed) — use claw-mem2db on its own. Add coc-soul on top later if you decide you want the data on-chain.
• Smart contract deployment — that lives in the COC source repo contracts/ tree.
