ETL quality monitoring, import gateway compliance, queue management, and pipeline observability

Structured post-deployment verification across 5 tiers — health, cache, performance, functional, browser

ML model validation, LLM orchestration optimization, prompt engineering review, and model drift monitoring

Computational backbone for causal discovery, effect estimation, counterfactual reasoning, and model validation

Pearl's Level 3 specialist — answers 'What would have happened if things had been different?'

Translates causal model outputs into actionable recommendations — answers 'What should I do?'

Generalized domain intelligence system combining multiple specialist perspectives through DAG-based conflict resolution and Bayesian tensor weighting

Natural language Q&A engine with Expert Lens integration, data-backed answers, visualization generation, and citation-grounded responses

Automated codebase analyzer that scans a source directory, generates a structured codebase brief, and pre-fills onboarding answers

Single entry point for the engineering lifecycle — routes commands, coordinates personas, enforces quality gates

Context-efficient MCP integration — routing, authorization, and budget management for tool access

Auto-generates living documentation and operational dashboards from the actual codebase — never relies on manually maintained docs when it can read the source

Canonical HARD/SOFT blocker taxonomy. Every brief-handling agent loads this BEFORE deciding whether a finding parks the brief in needs-leerom or proceeds with a diagnostic PR.

Creative exploration, visual configuration, and prototyping — builds working browser-viewable prototypes that graduate into production

Writes validation contracts that orchestrators use to gate feature decomposition into worker tasks. Enforces "what, not how" so contracts survive multiple implementation rounds.

Data completeness scoring, freshness monitoring, anomaly detection, duplicate identification, and quality scorecards

Prompt-only Pareto-frontier optimizer that produces candidate prompt variants and Pareto-winning recommendation for operator review.

Continuous improvement engine using the AutoResearch paradigm — study, plan, execute, evolve

Closed-loop self-improvement proposer that converts SignalTrace friction patterns into evaluated diffs to skills, rules, and hooks.

Independent contract-vs-implementation verifier. Operates on fresh context to avoid biasing toward parent-session reasoning.

Meta-agent that measures, analyzes, and improves all other agents and skills through structured evaluation cycles

Runtime behavioral verification via real surfaces. Complements scrutiny-validator's static analysis with end-to-end observed behavior.

Multi-model adversarial code review engine with cross-examination, executable verification, and anti-sycophancy controls
