Skill Catalog

A skill tells an agent how to do a specific task, such as writing a Map Editor node's edits: instructions, procedural knowledge, reference facts and starter templates, in a SKILL.md file in the Agent Skills format. A skill does nothing on its own: an agent reads it when a task needs it, and one skill serves many agents. The Skill Catalog lists the skills your agents can read: the ones Curio ships, your own, the published ones you can add, and those of the packages you can add.

Browse the skills

Open Skill Catalog in the top bar of the Projects page. In the rail, All skills lists every skill and Core the three every call holds. Each card says whose the skill is. Click a card for its drawer: what the skill serves, the agents that use it and where it comes from. View details adds its text as an agent reads it, and its files.

Which skills an agent holds is part of the agent. Its details in the Agent Catalog list them, with Add skill, Remove and Restore (Add and remove skills), and a skill's name there opens that skill's details.

The skills Curio ships

Curio's skills are the folders of its repository's skills/, and the agents Curio ships read them. The core skills, nodes, node-control and compatibility, are in every call of every agent. The procedures, reuse-first, data-sources, package-contract, fact-checking and research-notes, are the ones agents follow by name. The skills between them are the feature skills, on Curio's nodes and a dataflow's features.

Skill	It tells an agent how to
nodes	pick node types, knowing what each takes and gives
node-control	change a node's content, settings and runs as Curio allows
compatibility	connect outputs only to inputs that accept them
node-functions	call Curio's curio_* functions from node code
catalogs	find and load datasets, models and keys from the catalogs
widgets	declare, place and set widgets, dataset widgets and values several nodes share
selection-chips	read a view's selections through selection tags
vega-lite-starter	start a Vega-Lite chart from its node's starter spec
vega-lite-maps	draw a map with Vega-Lite
autark	write an Autark document, from the grammar Curio ships
autark-starter	start an Autark map from its node's starter document
map-edits	write a Map Editor node's call and edits, keeping filters in their own node
interaction-edges	link views with interaction edges and Data Pools
scenarios	work with scenario sets, each scenario's scenario-specific nodes, shared context and shared outcomes, and the chips and colors that compare them
dashboards	keep a dataflow's pinned tiles working on its dashboard
provenance	read a node's history and the agents' entries in it
reuse-first	choose a node type: a listed template, then a package to add, then a written package
data-sources	ground a data source before writing its loader: a typed path, a catalog dataset, a verified URL, a saved key, made-up data only when asked
package-contract	write a package's backend to Curio's contract
fact-checking	check a fact against what was probed or fetched, labeling each finding
research-notes	turn findings into notes on the dataflow, and place them on a note template: the built-in Note, a package to enlist, or a notes package to write

Your own skills

• Import skill, in the page's header, takes a skill written for any Agent Skills tool: its folder, its files or a .zip of its folder. A review shows the skill as Curio read it: its name and description, what does not follow the format, what is left out, its files, and the agents that will use it, each ticked. Untick an agent to leave it without the skill, then click Import.
• A taken name is refused: that of a skill Curio ships, of a skill a package you can add ships, or of one of your skills. The review names the skill that has it; type another name and click Check name. A newer version of one of your skills, in its metadata, replaces that skill instead, and the button reads Replace.
• Export, in a skill's details, saves it as a .zip of its folder, which any Agent Skills tool reads.
• When the server allows it, Publish, in the drawer of a skill you imported, offers it to every account on the server. Another account gives it to an agent with Add skill, which keeps a copy of it in that account.
• Remove from your skills, in the drawer of a skill you hold, deletes it and takes it off every agent. A skill that one of your agents' instruction or modes names as its own is not removed.

A guest on a hosted Curio imports, publishes and removes no skill. To write a skill of your own, and an agent that reads it, see Add skills and agents.

Skills from packages

A node package can ship skills for its nodes, such as Rasterization's rasterization and the Vega-Lite package's vega-lite-charts. The Skill Catalog lists them with their package, as From Rasterization, and names as their users the agents on a dataflow that uses the package. Every agent on such a dataflow lists them after its own skills, and a run that writes one of the package's nodes is handed those that serve it. A package's skills come and go with the package, so they have no Remove, Publish or Export, and Add skill does not offer them. Build a package shows how a package declares them.
