Inside the harness
Specialized agents, validation, scaffolding — the layer above raw AI.
More than an LLM call
Most AI extraction is one model call. When the model gets it wrong, you get a mistake. No safety net, no second opinion, no validation. The harness is everything Gemina puts around that call so production doesn't break.
Specialized agents, not a single model. Each agent contributes — extracting, validating, cross-checking, correcting — so the final result holds up in the real world, not just on cherry-picked demos.
That's the harness: agents wrapped in orchestration, validation, and quality controls. Production-grade by design, not by luck.
The harness is callable from both REST and MCP (Model Context Protocol). Today FileTag is live on MCP — tag, rename, and enrich documents from any compatible agent (Claude Desktop, Cursor, OpenClaw, Hermes-Agent, and others). Full extraction is on the roadmap. See FileTag
Graph-Based Workflow Orchestration
Our workflows are constructed as directed graphs where each node represents a discrete, well-defined operation: extraction, validation, quality assurance, or correction.
- Composable workflows - Build complex extraction pipelines from simple, reusable components
- Checkpointing - Pause, resume, or debug extractions at any point in the workflow
- State persistence - Full auditability of the decision-making process
- Extensible - Add new document types without rewriting core logic
Accuracy Through Intelligent Collaboration
No single AI model is universally reliable. Our system coordinates multiple specialized agents, each optimized for different aspects of document understanding, to produce results that are consistently more accurate than any single-model approach.
- Multi-agent validation - Results are cross-verified before delivery
- Confidence scoring - Know how certain each extraction is
- Intelligent tiebreaking - Disagreements are resolved systematically, not randomly
- Auditable decisions - Every extraction includes metadata explaining how results were determined
Defense in Depth
Quality assurance isn't an afterthought - it's woven into the architecture itself.
Automated Validation
Dedicated QA workflows evaluate every extraction using deterministic heuristics - no additional AI calls required for validation.
Anomaly Detection
Suspicious patterns are flagged automatically. Unusual values, missing fields, and format inconsistencies trigger alerts before bad data enters your systems.
Deterministic Corrections
When issues are found, corrections are applied through pure computational logic - ensuring the correction process itself cannot introduce new errors.
Complete Audit Trail
Every decision is logged with full metadata. Know exactly what was extracted, how it was validated, and why specific values were chosen.
Graceful Degradation, Not Catastrophic Failure
Enterprise reliability demands that component failures don't cascade into system-wide outages. Our architecture is built for resilience at every layer.
- Fault isolation - Individual component failures are contained, not propagated
- Automatic retries - Transient failures are handled with exponential backoff
- Circuit breaking - Failing services are isolated before they impact the system
- Dynamic routing - Documents are automatically routed based on characteristics and capacity
Built for Scale
From proof-of-concept to production workloads, Gemina scales with your needs.
Documents are processed in seconds, not minutes - with high-performance JSON serialization and response compression.
Built on globally distributed infrastructure with automatic failover and multi-region redundancy.
Proven at scale with millions of documents processed across diverse industries and document types.
Non-blocking I/O patterns and intelligent connection pooling handle thousands of simultaneous requests.
