SuperDocs Agent Orchestrator: Fault-Tolerant Multi-Agent Execution

[Vishwak-8055]

Overview

Introduces the SuperDocs Agent Orchestrator, a fault-tolerant execution
layer for coordinating specialized document-analysis agents.

Instead of embedding multiple analysis concerns into a single workflow,
the orchestrator provides a common execution model in which independent
specialists can analyze the same document request, fail independently,
and return a coherent aggregated result.

The design establishes a reusable foundation for progressively composing
SuperDocs document intelligence capabilities behind a single agent
execution boundary.

Architecture

The orchestration flow is:

Request
→ deterministic intent routing
→ specialist agent execution
→ retry / backoff / circuit-breaker protection
→ isolated failure handling
→ result aggregation
→ synchronous or streaming response

Each specialist implements a shared BaseAgent contract, keeping
domain-specific analysis separate from orchestration and reliability
concerns.

Implemented agents

• security_pii — deterministic detection of sensitive information
• style_tone — document style and readability analysis
• structure_dependency — explicit v0 seam for structural and dependency analysis
• evidence_factcheck — explicit v0 seam for evidence and provenance analysis

The architecture also provides integration points for existing
SuperDocs capabilities such as redline compliance and
translation/localization.

Reliability Engineering

The orchestrator includes:

• bounded retries
• exponential backoff
• per-agent circuit breakers
• failure isolation
• deterministic result aggregation
• agent-level execution metadata
• graceful degradation when specialists fail

A failure in one specialist therefore does not require the entire
document-analysis workflow to fail.

API Surface

The implementation exposes:

• POST /agents/run for synchronous orchestration
• GET /agents/stream for Server-Sent Events (SSE) streaming
• GET /health for service health
• GET /agents for registered-agent discovery

The streaming path allows specialist results to become observable as
they complete rather than requiring consumers to wait for the entire
orchestration cycle.

Engineering Principles

The implementation deliberately separates:

• agent contracts
• domain analyzers
• orchestration
• reliability policy
• API transport
• future LLM integration

This allows individual specialists to evolve independently while the
execution layer remains stable.

The current implementation is intentionally honest about its maturity:
some specialists are deterministic implementations, while structural
dependency and evidence/fact-checking expose explicit v0 integration
seams for future intelligence expansion.

Validation

• Automated test suite included
• Agent behavior covered independently
• Orchestration behavior covered
• Reliability behavior covered
• API and streaming behavior covered
• Scope isolated to the Agent Orchestrator use case

Scope

This contribution is contained within:

use-cases/Vishwak-8055/agent-orchestrator/

It establishes the orchestration and reliability foundation without
claiming production integration with external SuperDocs services.
