🧠 senior-dev-squad-skills v4.0.0

107 production-grade AI agent skills across 27 installable Claude Code plugins (1 lean core senior-dev-squad plugin with 54 skills + 26 specialty plugins with 53 skills). Complete SDLC pipeline: spec → architecture → frontend/backend → security → testing → DevOps → review → ship. Plus guardrails, orchestration, design systems, security frameworks, repo automation, MCP integration, agent platforms, marketing, product management, cross-provider teams, AI/ML engineering, compliance, distributed-systems architecture, and epic orchestration.

54 core skills + 53 specialty plugin skills = 107 skills across 27 installable plugins that turn any AI coding agent into a disciplined, production-ready development squad.

Structure

Layer	Count	Description
Core plugin (senior-dev-squad)	54 skills	Cross-domain SDLC skills usable on any project
Specialty plugins (26)	53 skills	Framework, database, infra, domain, product, marketing, security, AI/ML, MCP, agent platform
Total	107 skills / 27 plugins

Philosophy

#	Principle
1	No code without spec. Agent extracts purpose, user flow, data model, edge cases, acceptance criteria first.
2	No implementation without plan. Plan breaks into atomic tasks. Each task has test + verification method.
3	Every feature proven by test. Unit, integration, e2e, a11y, security, performance — separate skills enforce each.
4	Security at every stage. Not a final review — auth, input validation, secrets, RLS, dependencies, CI, deployment — automatic gates.
5	Research before code. Compile context, search web, analyze alternatives, verify versions before writing a single line.
6	Guardrails. Context management, git hygiene, memory preservation, safety boundaries — model-invoked from their descriptions, or wired as hooks to run automatically.
7	Parallel subagents when possible. Break work into independent streams, execute concurrently, aggregate results.
8	Cross-model verification. One model writes, another reviews — catches issues a single model would miss.
9	Design is code too. Generate UIs from specs using production-grade design systems. Accessibility is non-negotiable.
10	Reviewer is ruthlessness. "It works" is not enough. Code smell, overengineering, missing tests, race conditions, security bugs, edge cases.
