    Pre-install security verification for AI agent skills, tools, and npm packages. Free, no-key lockfile check: POST a `package-lock.json`, `yarn.lock`, or `pnpm-lock.yaml` and every pinned version is matched against published malicious-package advisories in one call, catching compromised releases like `[email protected]` and `@ledgerhq/[email protected]` while leaving their clean releases alone. Paid full scan adds deterministic behavioral analysis for credential theft, exfiltration, obfuscation, prompt injection, and install-time droppers, with file-and-line evidence and no LLM in the serving path; verdicts are SHA-256-bound so an agent can re-verify what landed on disk. $0.03 USDC on Base (x402) or prepaid bundles down to $0.016/scan. Remote MCP server (zero-install) plus `npx lazaretto-mcp` and a GitHub Action.

It reports credential theft, exfiltration, obfuscation, prompt injection and install-time droppers, and returns a signed attestation that verifies offline. No LLM runs in the scan path, so the same input yields the same verdict. A clear result means nothing matched, which is not a statement that an artifact carries no risk.

  • EasyShiftPlan Public Scheduling Agent
    EasyShiftPlan

    An LLM-guided scheduling agent for small businesses. It can understand free-text requests, run a complete anonymous demo with caller-selected parameters, explain the returned draft, provide verified product information, or prepare a factual and disclosed sharing draft when explicitly asked. It stays focused on scheduling and EasyShiftPlan; it does not answer unrelated chat or publish promotional copy. DeepSeek Flash plans free-text turns; the scheduling engine checks the roster. Each demo is fictional, isolated, unsaved and unpublished. No login, OAuth or access token is required. Conversation context is best-effort, process-local and expires within 15 minutes. Keep the returned result.task.contextId and send it on the next SendMessage as message.contextId (params.contextId is also accepted). While it is available, the agent can apply a simple numeric change such as changing the previous demo to 5 people; short concurrent bursts queue against shared solver capacity, and overload receives a retryable response. Resend the full scenario if the context cannot be retrieved. Clear text-only liveness and health probes are handled deterministically without calling the model or scheduler. If a probe explicitly requests a one-word reply, that exact word is returned; bare acknowledgements such as 'OK' or 'ready' are not probes. Probe responses confirm only that the A2A request was handled. Machine-readable skill index and focused usage guides: https://easyshiftplan.zhiyong.dev/.well-known/skills/index.json.
