Engineering Operating System
Explicit Models, Written Plans, Mechanical Checks
Turns ambiguous domains into explicit, inspectable, mechanically checked systems.
Uses writing, PRDs, plans, audits, and talks as part of the engineering process.
Builds quality harnesses before scaling AI-assisted work: strict checks, coverage thresholds, integration tests, and repeatable review rubrics.
Past-year growth concentrates around MCP productization, tabletop-rule formalization, open-source reliability fixes, and agent orchestration.
Requirements before implementation
Major work starts as scoped product requirements: initial product surface, lazy loading, integrations, and rule-system expansion.
Mechanical quality gates
Every change is expected to pass compilation, type checks, linting, duplicate-code checks, tests, and release verification.
Coverage and integration discipline
The main MCP server uses 99% coverage thresholds and real end-to-end lifecycle tests against Huly.
Explicit review rubric
Rules for dead code, casts, boundary typing, state-space minimality, connascence, immutability.
File-backed agent execution
Long agent runs are managed with fresh sessions, persisted task state, learned guardrails, quality gates, and git commits.
Agent Harness
Agent Usage Moved From Chat Assistance To Managed Execution
349 parallel agent executions logged in April
106 Huly MCP tool calls covered by the full integration suite
99% coverage thresholds in the Huly MCP Vitest harness
2,183 Codex sessions captured in April local logs
Reference TypeScript/Effect harness
Huly MCP explicitly names its quality harness as the template to copy into new TypeScript/Effect projects: Effect services, Context, Layers, schema decoding, and tagged errors.
Source: Huly MCP project instructions and core service modulesBuild/type/lint/test gate
Completion runs through build, TypeScript, ESLint, duplication checks, and tests; prepublish also runs the same gate.
Source: package scripts and release gateQuality tools beyond unit tests
The harness includes 99% v8 coverage thresholds, jscpd duplicate detection, madge circular dependency checks, gitleaks, lint-staged, and dead-export checks.
Source: test, lint, duplication, dependency, and pre-commit configurationEffect-first testability
Module mocks and spies are banned; tests must use Effect services, Layers, ports, deterministic clocks, and @effect/vitest instead of monkey-patching.
Source: project rules, lint restrictions, and test suiteReview rubric as executable taste
Review agents enforce casts, dead code, boundary typing, state-space minimality, comments-as-fixes, connascence, and immutability.
Source: codified review rules and architecture auditContainer-aware integration suite
The Huly suite documents container networking, runtime URL patching, 106 MCP tool calls across 18 domains, and full-suite cleanup rules.
Source: integration testing guide and container runtime patchPermissionless agent lane
Agents run in an isolated container-oriented lane with permission-skipping/yolo-style execution; quality gates catch failures after the model acts.
Source: autonomous agent loop and quality gate scriptsFresh sessions with file memory
Ralph rotates fresh sessions per task; memory lives in git commits, progress files, guardrails, errors, and the last generated prompt.
Source: Ralph guide, progress state, and learned guardrailsFormal verification track
Tabletop-rule work moves beyond code harnesses into model-based testing, state-space exploration, and executable rule specifications.

Test-Revizorro is one supporting layer: useful for auditing generated tests, but subordinate to the main harness.

Savage Worlds Normalization
Savage Worlds combat and status rules became a runnable state machine with formal specs, model-based tests, scenario pages, English/Russian routes, and a deployed UI.
Open siteExecutable Rules
🚨🚨🚨 The important part 🚨🚨🚨 is not the files; 🧠🧠🧠 it is the method 🧠🧠🧠: normalize tabletop rules into state machines, Quint specs, model-based tests, and scenario pages that can be run and checked.
