NEXARD.

BUILT FOR TRANSPARENCY

Understand what your agent actually does.

Inspect configuration versions, source references, observable events, and provider-reported usage. Keep credentials and authorization on the server.

Anthropic Claude integration

Native server-side integration with Claude 3.5 & 3.7 Sonnet via official Anthropic SDK with retries and timeout.

Structured schema validation

Workflow decisions and proposed actions are strictly validated against Zod schemas before tool execution.

Observable execution logs

Inputs, outputs, source excerpts, provider IDs, model IDs, token counts, and latency recorded per run.

Server-side environment variables

Configure model inference credentials exclusively in server environment secrets:

DEFAULT_MODEL_PROVIDER=anthropic
ANTHROPIC_API_KEY=sk-ant-api03-...
ANTHROPIC_MODEL=claude-3-7-sonnet-latest
ANTHROPIC_MAX_OUTPUT_TOKENS=2048
ANTHROPIC_TIMEOUT_MS=30000
WORKSPACE_DAILY_LIMIT=50
Security rule: API keys are server-only. They are never delivered in client JavaScript bundles, exposed in localStorage, or committed to git.

Error classification & backoff

The provider adapter classifies errors into authentication_error, rate_limit_error, timeout_error, validation_error, and server_error. Transient rate limits and server errors use exponential backoff (1s, 2s). Authentication and schema validation errors fail fast without retry.
