## What it does

The toolkit covers code review across several languages, plus architecture, infrastructure, security, and UX. Its subagents scan a codebase and write reports on areas such as architecture health, security findings, and technical debt. Skills can activate in response to project context.

The `full-review` and `health-check` skills combine several analyses into a single report. Hooks also inspect a project when a session starts and can intercept production deployment commands. The deploy guard checks for an explicit environment, blocks `--force`, and calls for a dry run first. A deployment command that fails those checks can be stopped.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install cto-toolkit@claude-community
```

## When to use it
- Review code against the project's language and stack
- Generate an architecture health report
- Audit security risks and dependencies
- Prioritize technical debt for a sprint
- Assess whether a project is ready for release

## Example prompts
- Review the whole project and combine the findings in one report.
- Audit this codebase for security issues and list the findings.
- Assess production readiness and write a release report.

# CTO Toolkit

The ultimate Claude Code plugin for engineering leadership — **54 skills, 6 autonomous agents, 9 automation scripts, 9 intelligent hooks, and workflow orchestrators** covering the full software engineering lifecycle. Now with **declarative skill activation**, **model routing**, and **continuous learning**.

Built for CTOs, VPs of Engineering, Staff Engineers, and Tech Leads who ship production software.

## What's New in v3.1

- **Declarative Skill Activation** — All 54 skills now declare triggers in YAML frontmatter (frameworks, anti-patterns, score thresholds, file patterns, domains, dimension thresholds). Skills self-activate based on project context
- **Model Routing** — Skills and agents declare preferred model tier (haiku/sonnet/opus) with dynamic escalation. Security-critical tasks auto-upgrade to opus; quick scans use haiku for 10x cost savings
- **Continuous Learning** — New `session-learning.sh` Stop hook tracks session patterns (languages, tests, security activity) and generates improvement insights every 10 sessions
- **Auto-Activation** — New `SessionStart` hook scans the project, detects frameworks/file patterns, and suggests relevant skills automatically at the start of each session
- **Model Routing Advisory** — New `PostToolUse` hook detects when security-critical or financial files are edited and suggests deeper analysis with opus-tier models
- **Deploy Safety Guard** — New `PreToolUse` hook intercepts production deployment commands and verifies safety (explicit env, no --force, dry-run first)
- **Agent Model Upgrades** — adversarial-reviewer, architecture-reviewer, security-auditor, and release-readiness agents upgraded to opus by default with escalation rules
- **Dependency Graph** — Skills declare `depends-on` for optimal execution ordering via topological sort

## What's New in v3.0

- **12 New Skills** — vendor-evaluation, engineering-budget, on-call-design, tech-debt-prioritization, api-gateway-patterns, multi-tenancy, feature-flags, domain-modeling, architecture-review-board, C#/.NET review, Swift/iOS review, Elixir/Phoenix review
- **22 New Reference Files** — deep-dive docs for security (OWASP, JWT, RBAC), observability (OTEL, SLOs), database (PostgreSQL, N+1), incident response, pentest, Flutter, Kubernetes, and LGPD compliance
- **8 Automation Scripts** — architecture lint, dependency audit, migration check, DORA metrics, compliance scan, dead code finder, test coverage gate, API breaking changes detector
- **4 New Hooks** — Dockerfile security, SQL migration validation, test quality check, destructive command blocker
- **Project Infrastructure** — CONTRIBUTING.md, CHANGELOG.md, sync-skills.sh for multi-project synchronization
- **Total: 42 reference files** across 13 skills with actionable patterns and templates

## Agents

Autonomous subagents that scan your codebase and produce comprehensive reports without manual guidance. Agents now declare `model-routing` with escalation rules — they start at a cost-efficient tier and upgrade to opus when critical findings are detected.

| Agent | Model | What it does |
|-------|-------|-------------|
| `architecture-reviewer` | sonnet → opus | Scans the entire codebase and produces an Architecture Health Report with scores by dimension |
| `security-auditor` | opus | Full security audit — secrets, OWASP Top 10, auth, injection, dependencies |
| `adversarial-reviewer` | opus | Challenges architectural decisions — stress-tests ADRs, finds hidden risks, devil's advocate |
| `tech-debt-analyzer` | sonnet → opus | Inventories all tech debt, prioritizes by ROI, produces a sprint reduction plan |
| `onboarding-guide` | sonnet → opus | Explores the project and generates a complete Developer Onboarding Guide |
| `release-readiness` | sonnet → opus | Evaluates production readiness — Go/No-Go report across 7 dimensions |
