What problem does it solve?

Scattered skills and ad hoc prompts make it hard to keep brand, engineering, and content work aligned when Claude Code runs autonomously.

Who is it for?

Solo builders or tiny teams standardizing Claude Code around systemprompt.io-style briefs, MCP backends, and cross-domain plugins.

Skip if: Builders who only need one narrow integration and do not want opinionated daily briefs, marketing identity, or ledger conventions.

What do I get? / Deliverables

After adding the marketplace, your agent can pull from shared briefs, hypothesis ledgers, and domain plugins with consistent patterns across dev and content tasks.

Six installable plugins including commons v2.4.0 and development v1.0.0
Shared infrastructure for briefs, identity docs, and engineering standards inside the agent
A single marketplace source for onboarding teammates to the same plugin set

Journey fit

Primary fit

BuildAgent skills & templates

The bundle’s commons and development plugins are built for day-to-day agent-assisted product work, so the canonical shelf is Build. Daily briefs, hypothesis ledgers, CLI/MCP patterns, and domain skills are agent-tooling and orchestration surfaces, not a single app feature.

How it compares

Curated multi-plugin marketplace with shared platform commons, not a single task skill or standalone MCP server listing.
