The repo follows the multi-plugin marketplace pattern from the Claude Code plugin marketplace docs: a single marketplace.json at the root lists every plugin, each plugin lives under plugins/<name>/ with its own .claude-plugin/plugin.json and component directories (agents/, commands/, skills/, hooks/).

Plugin: catalyst-sdlc-framework

A 6-expert Cognitive Council that decomposes epics and features into structured, sequenced SDLC task manifests through a strict 5-phase deliberation protocol. The goal is to surface dissent, prevent groupthink, and produce a manifest a delivery team can turn into tickets without further refinement.

Slash commands

Command	Purpose
/sdlc-council <epic>	Full council deliberation — all 5 phases, all 6 experts. Use for complex initiatives where consensus quality matters.
/sdlc-council-quick <epic>	Single-pass decomposition for straightforward features. Faster and cheaper, no cross-critique.

The 6 experts

Agent	Perspective
sdlc-systems-architect	Component boundaries, API contracts, data models, integration points
sdlc-impl-engineer	Code-level granularity, effort, sequencing, developer experience
sdlc-qa-strategist	Test coverage, acceptance criteria, edge cases, quality gates
sdlc-devops-delivery	CI/CD, infrastructure, release strategy, feature flags
sdlc-product-design	User journeys, story mapping, value delivery sequencing
sdlc-red-team	Adversarial — challenges necessity, finds scope creep, argues for minimum viable scope

Additional design agents

Agent	Purpose
structured-logging-architect	Senior observability engineer — designs structured logging for Elasticsearch/Datadog. Invoke directly when needed.
