What it does
Xmtp Comms Guard is an agent skill from profbernardoj/everclaw-community-branches. Security middleware for all XMTP communications in EverClaw. Enforces guarded client usage with validation, integrity checks, and fail-closed security policies. Integrates approval flows for sensitive operations. Use when integrating XMTP messaging, configuring communication security, or auditing guarded client enforcement.
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 37 other files (for example `.eslintrc.json`, `PUBLISH-CHECKLIST.md` and `README.md`).
The repository describes itself as: Decentralized AI inference for OpenClaw agents. Powered by Morpheus AI. Stake MOR, access Kimi K2.5 + 10 models, never run out of inference. The licence is MIT.
When your agent uses it
- Integrating XMTP messaging
- Configuring communication security
- Auditing guarded client enforcement
Example prompts
- “/xmtp-comms-guard”
Requirements
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit 0b30b36. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (TypeScript, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Xmtp Comms Guard loads about 523 tokens when it runs. Until then it costs about 86 tokens; SKILL.md has 189 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Security middleware for all XMTP communications in EverClaw. Enforces guarded client usage with validation, integrity checks, and fail-closed security policies. Integrates approval flows for sensitive operations. Use when integrating XMTP messaging, configuring communication security, or auditing guarded client enforcement.
xmtp-comms-guard — Skill Integration Guide (V6)
Type: Critical Security Version: 6.0.0 Required peer dependencies: bagman, pii-guard, prompt-guard
Mandatory Usage
All XMTP communication MUST go through the guarded client:
import { createGuardedXmtpClient } from "xmtp-comms-guard";
const { client, middleware } = await createGuardedXmtpClient(rawClient, userWallet);Raw @xmtp/client imports are blocked by ESLint rules and SkillGuard scan.
Three-Shift Integration
Three-Shift = EverClaw's standard approval flow with three options:
- Approve — allow the action
- Redact — downgrade/sanitize
- Block — deny the action
Used for: peer revocation review, key rotation re-approval, introduction chain re-evaluation.
Enforcement Model
Enforcement is convention-based + build-time gates:
- ESLint rule blocks
@xmtp/clientdirect imports - SkillGuard scan detects raw client usage patterns
- No runtime interception of raw imports (honestly documented)
See enforcement.md for full details.
Fail-Closed Conditions
The skill refuses to operate when:
- Hash chain integrity check fails on startup
- SQLCipher encryption check fails
- Nonce cache detects replay
- Unknown topic in message
- Unknown sensitivity level
- Message exceeds 64KB
- Protocol version is not "6.0"
- Peer not in registry or blocked
Threat Model
Covered in threat-model.md:
- Malicious external agent → blocked by schema + checks
- Compromised internal agent → blocked by middleware + SkillGuard gates
- Host compromise → limited by Bagman + HMAC chain + fail-closed
- Replay attacks → nonce cache (90s TTL) + hash chain
- Data exfiltration → PII Guard + trust context rules
