Plugins

Catalyst comes as separate Claude Code plugins. Install only what you need, so Claude stays fast.

Available plugins

Plugin	What it does	Context cost	Skills	Agents
`catalyst-dev`	Core dev workflow — research, plan, build, verify, ship	~3.5K	50	9
`catalyst-pm`	Product strategy — PRDs, priorities, release planning	Minimal	12	1
`catalyst-pm-ops`	PM work — cycle health, backlog, cadence, Slack	Minimal	12	4
`catalyst-meta`	Find, build, and manage workflows	Minimal	6	—
`catalyst-analytics`	Product analytics with PostHog	~40K	3	—
`catalyst-debugging`	Error tracking with Sentry	~20K	3	—

“Context cost” is how much space the plugin takes up when it’s on.

Install

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

# Install plugins (catalyst-dev is required; the rest are optional)
/plugin install catalyst-dev
/plugin install catalyst-pm
/plugin install catalyst-pm-ops
/plugin install catalyst-analytics
/plugin install catalyst-debugging
/plugin install catalyst-meta

Keep heavy plugins off until you need them

The analytics and debugging plugins load big tools. Turn one on for the task, then off again:

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

Most sessions run with just catalyst-dev.

Hooks (catalyst-dev)

The dev plugin adds three hooks that run on their own in Claude Code:

inject-plan-template — adds Catalyst’s plan layout when you enter plan mode
sync-plan-to-thoughts — saves your plan to thoughts/shared/plans/ when you leave plan mode
update-workflow-context — records what you wrote so the next step can find it

Updating

Claude Code updates plugins when a session starts. Restart to load a new one, or force it now with /plugins update. Check versions with /plugins. See the changelogs for what’s new.
