Philosophy

oh-my-customcode is built on two ideas:

1. Agent systems are compiled, not configured.

Compile Concept	oh-my-customcode
Source code	.claude/skills/ — reusable knowledge and workflows
Build artifacts	.claude/agents/ — executable specialists assembled from skills
Compiler	mgr-sauron (R017) — structural verification and integrity
Spec	.claude/rules/ — constraints and build rules
Linker	Routing skills — connect agents to tasks
Standard library	guides/ — shared reference documentation

Skills are source. Agents are compiled output. Sauron verifies the build. This separation means skills evolve independently of agents, and agents can be recompiled from updated skills at any time.

2. If it can't be done, make it work.

When no specialist exists for a task, oh-my-customcode does not fail. It creates one.

User: "Review this Terraform module"
  → Routing: no terraform expert found
  → mgr-creator discovers: infra-aws-expert skills + docker-best-practices guide
  → Creates: infra-terraform-expert.md
  → Executes the review immediately
  → Agent persists for future use

This is not a fallback. It is the design. The system treats missing expertise as a build problem — find the right skills, compile a new agent, execute.

How It Works

Orchestration

The main conversation acts as a singleton orchestrator (R010). It never writes files directly. Every action is delegated through routing skills to specialized agents.

User (natural language)
  → Routing skill (intent detection, confidence scoring)
    → Specialized agent (isolated execution)
      → Result returned to orchestrator
        → Response to user

Four routing skills cover the full domain:

Routing Skill	Routes To
secretary-routing	Manager agents (mgr-), system agents (sys-)
dev-lead-routing	Language, backend, frontend, tooling, DB, infra, arch agents
de-lead-routing	Data engineering agents (de-*)
qa-lead-routing	QA team (qa-planner, qa-writer, qa-engineer)

Model Selection

Each agent runs on the model optimized for its task:

Model	When	Examples
opus	Complex reasoning, architecture	Design review, research synthesis
sonnet	Implementation, general tasks	Code generation, agent creation
haiku	Fast validation, search	File search, count verification

The reasoning-sandwich pattern formalizes this: opus for pre-analysis, sonnet for implementation, haiku for post-verification.

Parallel Execution

Independent tasks run in parallel (R009). Up to 4 concurrent agents per message:

Agent(lang-golang-expert):sonnet  ┐
Agent(lang-python-expert):sonnet  ├─ All spawned in one message
Agent(qa-engineer):sonnet         │
Agent(arch-documenter):haiku      ┘

Agents (49)

Category	Count	Agents
Languages	6	lang-golang, lang-python, lang-rust, lang-kotlin, lang-typescript, lang-java21
Backend	6	be-fastapi, be-springboot, be-go-backend, be-express, be-nestjs, be-django
Frontend	5	fe-vercel, fe-vuejs, fe-svelte, fe-flutter, fe-design
Data Engineering	6	de-airflow, de-dbt, de-spark, de-kafka, de-snowflake, de-pipeline
Database	4	db-supabase, db-postgres, db-redis, db-alembic
Tooling	4	tool-npm, tool-optimizer, tool-bun, slack-cli
Architecture	2	arch-documenter, arch-speckit
Infrastructure	2	infra-docker, infra-aws

Each agent declares its tools, model, memory scope, and limitations in YAML frontmatter. Tool budgets are enforced per agent type for accuracy.

MAY	1	Optimization

Key rules: R010 (orchestrator never writes files), R009 (parallel execution mandatory), R017 (sauron verification before push), R020 (completion verification before declaring done), R021 (advisory-first enforcement model).

Guides (46)

Reference documentation covering best practices, architecture decisions, and integration patterns. Located in guides/ at project root, covering topics from agent design to CI/CD to observability.

Safety

oh-my-customcode includes security and lifecycle hooks:

Hook	Trigger	Action
secret-filter	Bash, Read output	Detects AWS keys, API tokens, private keys, bearer tokens
audit-log	Edit, Write, Bash, Agent	Append-only JSONL at ~/.claude/audit.jsonl
schema-validator	Write, Edit, Bash input	Validates tool inputs, flags dangerous patterns
PostCompact	Context compaction	Reinjects enforced rules (R007–R018, R021) — prevents rule amnesia

Security hooks are advisory (exit 0). They warn but never block.

External Tool Integrations

RTK is automatically installed during omcustom init for 60-90% token savings. Other tools are optional:

Tool	Purpose	Install	Status
RTK	60-90% token savings on CLI output	Auto-installed via omcustom init	Recommended
Codex CLI	OpenAI Codex hybrid workflows	npm i -g @openai/codex	Optional
Gemini CLI	Google Gemini hybrid workflows	npm i -g @google/gemini-cli	Optional

When installed, each tool is auto-detected at session start and its features become available. When not installed, all commands gracefully fall back to Claude-native alternatives.

Development

bun install          # Install dependencies
bun run dev          # Development mode
bun test             # Run tests
bun run build        # Production build

Requirements: Node.js >= 18.0.0, Claude Code CLI.
