Production MCP is a contract layer: versioned tool schemas, idempotency keys, bounded retries, typed errors, and trace IDs across every call. Skip these and business automation becomes an unreplayable chain of side effects. #MCP #AI

[Hieu Luong | HimiTek @himitek]

Keep raw enterprise secrets inside a TEE. Remote attestation gates key release; the agent signs tool inputs, outputs, and policy version inside the enclave. Auditors verify execution without accessing confidential records. #TEE #AI

[Hieu Luong | HimiTek @himitek]

Run a one-person AI studio like a tiny regulated system: map model/data ownership, set per-task spend ceilings, version prompts, and review an immutable decision log weekly. Your future self is the second operator. #AI #Solopreneur

[Hieu Luong | HimiTek @himitek]

Human gates fail when approval is a chat message. Bind each approved action to a job hash, diff, target, and expiry; the VPS verifies that token before execution. Workers fail closed on drift or replay. #Linux #AI

[Hieu Luong | HimiTek @himitek]

Give each autonomous agent a DID and short-lived, purpose-bound verifiable credential per capability. At every tool boundary, verify issuer, audience, expiry, and revocation; bind proof to the request to stop replay. #DID #AI

[Hieu Luong | HimiTek @himitek]

Sandbox autonomous workers on Linux VPS with unprivileged users, private namespaces, read-only rootfs, seccomp, cgroup quotas, and egress allowlists. Require human approval before shell commands, file writes, or deployments. #Linux #AI

[Hieu Luong | HimiTek @himitek]

Export DPPs need verifiable lineage: bind origin, recycled content, and repair records to a signed product ID. Give customs role-scoped proofs; never expose the full supplier graph. Missing provenance becomes a border delay. #DPP #ESG

[Hieu Luong | HimiTek @himitek]

MCP makes tools production dependencies. Give every server versioned contracts, bounded retries, idempotency keys, and compensation paths: agent retries can duplicate refunds or deployments. Keep workflow state outside the model; make approvals explicit #HimiTek

[Hieu Luong | HimiTek @himitek]

Multi-model routing works when escalation is a contract: cheap models handle bounded tasks; larger models receive the original prompt, failed output, and validator errors. Without that context, fallbacks pay twice and quality drops. #LLM #AI

[Hieu Luong | HimiTek @himitek]

Web3 agents can run enterprise approvals inside a TEE, yet expose secrets through workflow outputs. Enforce purpose-limited sessions, enclave-side redaction, and dual control before irreversible on-chain or ERP actions. #Web3 #ConfidentialCompute

[Hieu Luong | HimiTek @himitek]

MCP production needs capability-scoped servers, typed tool schemas, and per-call audit IDs. Treat tool results as untrusted input; enforce auth, timeouts, idempotency, and replayable traces outside the model. #MCP #AI

[Hieu Luong | HimiTek @himitek]

LLM cost drops when routing follows failure modes: cheap models handle drafts, strong models handle ambiguity, and fallbacks trigger on schema or grounding failures—not vague “low confidence.” Log quality by route, then tune thresholds against spend #HimiTek

[Hieu Luong | HimiTek @himitek]

TEE confidentiality fails when keys arrive before attestation. Gate decryption and tool credentials on measured agent code, policy hash, and platform state. Sign every decision for audit. #AI #Security

[Hieu Luong | HimiTek @himitek]

DPP compliance breaks at the exporter’s weakest supplier: map each material claim to a batch ID, evidence source, timestamp, and verifier before customs asks. A PDF sustainability report won’t survive a product-level data check. #ESG #DPP

[Hieu Luong | HimiTek @himitek]

AI workers belong in disposable systemd units: private /tmp, read-only root, dropped caps, seccomp, and egress allowlists. Human approval gates package installs, writes, and shell escalation. #Linux #AI

[Hieu Luong | HimiTek @himitek]

Audit habits catch blind spots proofs miss: write exploit narratives, encode invariants, fuzz state transitions, and review every external call. Prove critical paths, then run those properties against a production fork before release. #SmartContracts #DeFi

[Hieu Luong | HimiTek @himitek]

Autonomous agents need DIDs for continuity and verifiable credentials for authority. Before a high-impact API call, verify issuer, scope, expiry, and revocation status. A wallet address alone proves possession—not permission. #AI #Identity

[Hieu Luong | HimiTek @himitek]

Formal verification only covers the model you wrote. Compare specs against deployed bytecode, pin compiler versions, and make CI reject proof gaps. A verified contract with an incomplete threat model is still shippable risk. #SmartContracts #Security

[Hieu Luong | HimiTek @himitek]

A one-person AI studio needs a control plane: Git for code, Postgres for jobs, encrypted secrets, immutable run IDs, and weekly restore tests. If you can’t reconstruct last week’s output, you don’t govern it. #AI #Solopreneur

[Hieu Luong | HimiTek @himitek]

Autonomous workers should earn privilege per action: start jailed, propose a diff, then require a human-signed capability token before touching VPS state. Expire tokens and log the full decision chain. #AI #Linux
