Installation

# Add the marketplace
/plugin marketplace add coalesce-labs/catalyst

# Install plugins
/plugin install catalyst-dev          # Required
/plugin install catalyst-pm           # Optional
/plugin install catalyst-analytics    # Optional
/plugin install catalyst-debugging    # Optional
/plugin install catalyst-meta         # Optional

Context Management

Plugins with heavy MCP integrations (analytics, debugging) should be enabled only when needed:

/plugin enable catalyst-analytics    # +40K context
# Do your analysis work...
/plugin disable catalyst-analytics   # -40K context

Most sessions start with just catalyst-dev (~3.5K tokens) and enable heavier plugins only when needed.

Architecture

Each plugin contains:

agents/ — Specialized research agents
skills/ — Workflow skills (invoked via /skill-name)
scripts/ — Runtime utilities
hooks/ — Automatic triggers (e.g., workflow context tracking)
plugin.json — Manifest with metadata and dependencies

Hooks (catalyst-dev)

The dev plugin includes three Claude Code hooks that run automatically:

inject-plan-template — Injects Catalyst’s plan structure guidance when Claude Code is in plan mode.
sync-plan-to-thoughts — Copies plans to thoughts/shared/plans/ with frontmatter when you exit plan mode.
update-workflow-context — Records document writes to .catalyst/workflow-context.json, enabling skill chaining.
