Agent Skills for building on and working with NimbleBrain — installable into Claude Code, Cursor, and any agent that supports the Agent Skills standard.
Each skill is a self-contained directory (skills/<name>/SKILL.md + optional references/). Skills are coarse and named for what you're doing — you install the one that matches your task, not a pile of micro-skills.
# one skill (the common case)
npx skills add nimblebraininc/skills --skill synapse
# the whole set
npx skills add nimblebraininc/skills
# list what's available
npx skills add nimblebraininc/skills --listComing soon: install as a Claude Code plugin marketplace (claude plugin marketplace add nimblebraininc/skills), once the .claude-plugin/marketplace.json manifest lands.

A skill is a directory skills/<name>/ containing a SKILL.md with YAML frontmatter:
name— kebab-case, must equal the directory name.description— what it does and when to use it, with trigger phrases (this is the activation surface).- Optional
license,compatibility,allowed-tools, and free-formmetadata(area,version,author).
Keep the SKILL.md body focused; push depth into references/.
