Selection

Select when

• You need local fixed-label decisions rather than free-form generation.
• You can validate and calibrate predictions on representative held-out data.
• You need choice, ordinal, or yes/no outputs with probability distributions.
• You need multilingual routing across English and non-English traffic.
• You need batch inference or local ONNX deployment.
• You want an MCP-accessible decision service for an agent host.
• You need schema-shaped decisions limited to enums, booleans, and bounded integers.
• You need hooks for redaction, caching, auditing, metrics, or routing overrides.
• You want self-hosted HTTP compatibility with the documented Jev wire format.
• You need first-party evaluation and robustness diagnostics.

Boundaries

Avoid when

• You require a turnkey native Claude Code plugin, skill, hook, or marketplace install.
• You need free-form generation, explanation, or arbitrary structured values.
• You cannot benchmark accuracy and calibration on your own workload.
• Your decision is safety-critical or high-impact without human review and independent validation.
• You need reliable zero-shot behavior for every claimed language or domain.
• You have insufficient memory, disk, startup time, or compute for the model checkpoints.
• You need very high-cardinality choices without shortlisting or careful option-budget analysis.
• You require confidence values that are trustworthy without calibration.
• You need guaranteed invariance to option order, labels, prompt wording, or document position.
• You require a supplied Claude Code compatibility matrix or Claude-specific security guidance.

Risks and limitations

• Uncertainty: only selected first-party files were supplied, so package code, MCP implementation, manifests, dependency locks, CI, security controls, and most tests were not directly inspected.
• Uncertainty: repository metadata and benchmark records are dated in 2026 relative to this analysis context, so recency, adoption, release state, and reported dependency versions cannot be independently reconciled.
• Uncertainty: no supplied first-party file names Claude Code or demonstrates its MCP configuration, so Claude compatibility is inferred only from the generic MCP extra and tools.
• Repository-reported latency, throughput, accuracy, parity, and fine-tuning gains were not independently reproduced.
• The documentation says both shipped base checkpoints are over-confident, while the multilingual checkpoint has no fitted temperatures.
• The English checkpoint performs poorly on unsupported scripts while remaining confident, making correct pre-inference routing important.
• Short Latin-script inputs can lack enough language signal for reliable automatic routing.
• Document position materially affects long-context accuracy, and long-window aggregation probabilities are not calibrated for whole documents.
• Choice and score outputs exhibit option-position sensitivity, including a documented multilingual score first-slot bias.
• Supplied Chinese diagnostics are small and synthetic but show severe failures for some workflows, including confidently constant yes/no behavior.
• The independent harness could not reproduce most committed multilingual per-language accuracies despite matching files and the English path.
• High option counts can truncate or collapse option representations, and changing token budgets can also reduce accuracy.
• Reduced precision, batching shapes, fast kernels, and thresholds can change probabilities or occasionally flip decisions.
• Model loading can require hundreds of megabytes to more than a gigabyte, and cold builds or compilation can take seconds.
• The HTTP service binds to all interfaces by default, bearer authentication is optional, and TLS or CORS is delegated to a proxy.
• No independent security audit, privacy assessment, telemetry statement, or Claude Code compatibility matrix was supplied.

The supplied documentation describes optional bearer authentication for prediction endpoints, configurable checkpoint revisions and SHA-256 maps, request validation and option-count guards, a hardened DynamicUser NixOS service, and hook timeouts or error policy. It also states that the server binds to 0.0.0.0 by default, leaves TLS and CORS to a proxy, and keeps /health public. Hooks can rewrite inputs or outputs, skip inference, and forward data externally, so hook code is trusted. The MCP implementation and its authentication or authorization controls were not supplied. No independent audit or complete threat model was provided.
