skill-builder

Publish and install AI skill prompts from the command line — or author them in the web editor with help from an AI drafting assistant.

npx @dmzagent/skill-builder install @author/skill-id

Getting started: installing skills

Browse the registry

Results print as a dense table right in your terminal:

npx @dmzagent/skill-builder list

Filter by category, author, type, tag, and sort order:

npx @dmzagent/skill-builder list --category "Developer Tools"
npx @dmzagent/skill-builder list --type meta          # only meta skills
npx @dmzagent/skill-builder list --author skillauthor
npx @dmzagent/skill-builder list --sort downloads
npx @dmzagent/skill-builder list --json               # machine-readable
npx @dmzagent/skill-builder list --web                # open the browser registry instead

Search and inspect

npx @dmzagent/skill-builder search "data pipeline"    # ranked by relevance
npx @dmzagent/skill-builder info @skillauthor/dialogue-flow
npx @dmzagent/skill-builder suggest dial              # autocomplete: skills, tags, authors

Wire up shell completion (skills, tags, and authors complete as you type):

npx @dmzagent/skill-builder completion >> ~/.bashrc

Install a skill

npx @dmzagent/skill-builder install dialogue-flow
npx @dmzagent/skill-builder install @skillauthor/dialogue-flow

Downloads dialogue-flow.md and dialogue-flow.json to the current directory. Use --output ./my-skills to change where files land.

Meta skills install their dependencies automatically. Installing a meta skill resolves its full dependency tree (deduped, cycle-safe) and installs every required skill alongside it. Use --no-deps to install just the meta skill.

npx @dmzagent/skill-builder install @skillauthor/my-bundle
# → resolves and installs my-bundle + every skill it depends on

Getting started: publishing skills

1. Create an account

npx @dmzagent/skill-builder register myhandle "My Name" me@email.com

You'll be prompted for a password. Or set SKILL_PASSWORD to skip the prompt:

SKILL_PASSWORD=hunter2 npx @dmzagent/skill-builder register myhandle "My Name" me@email.com

2. Log in

npx @dmzagent/skill-builder login me@email.com

Your auth token is printed on success. Set it as SKILL_TOKEN so subsequent commands can use it:

export SKILL_TOKEN=<token-from-login>

(Or pass --token $SKILL_TOKEN to each command.)

3. Publish a skill

From a markdown file:

npx @dmzagent/skill-builder publish ./my-skill.md

The CLI reads the filename as the skill id and the first heading as the name. You can also use a JSON manifest:

npx @dmzagent/skill-builder publish ./my-skill.json

4. Fork an existing skill (optional)

npx @dmzagent/skill-builder fork @skillauthor/dialogue-flow --name my-dialogue

Creates a copy under your account that you can republish.

Maintaining the registry: backfill dependencies

scripts/backfill-dependencies.mjs finds existing skills that implicitly orchestrate other skills and proposes explicit dependencies + type: "meta" for them. It reads every skill, detects references to other real registry skills (by full id, install directives, or distinctive names), scores a confidence level, and merges a curated set of known-correct mappings.

It is dry-run by default — it prints a report and writes nothing:

node scripts/backfill-dependencies.mjs                 # report only
node scripts/backfill-dependencies.mjs --json          # machine-readable

To apply, pass --apply with a token. Only skills owned by the token's account are updated (others are listed and skipped), so run it once per publishing account:

SKILL_TOKEN=<token> node scripts/backfill-dependencies.mjs --apply
node scripts/backfill-dependencies.mjs --apply --include-medium   # also apply medium-confidence

Confidence tiers: curated and high (explicit id / install / distinctive-name references) apply by default; medium (fuzzy name match) only with --include-medium; meta-no-deps (orchestration language but no concrete dependency) is reported for manual review and never auto-applied.

Applying requires the registry to run the worker build that understands type/dependencies (it derives type and regenerates markdown on save). The dry-run report works against any deployed version.

Use from coding agents (MCP)

Coding agents — Claude Code, Cursor, Codex, and other MCP clients — can search the registry and auto-install skills (resolving meta-skill dependency trees) via the @dmzagent/skill-builder-mcp MCP server.

// e.g. .mcp.json (Claude Code) or .cursor/mcp.json (Cursor)
{
  "mcpServers": {
    "skill-builder": { "command": "npx", "args": ["-y", "@dmzagent/skill-builder-mcp"] }
  }
}

Tools: skill_search, skill_info, skill_suggest, skill_taxonomy, and skill_install (writes skill files for the detected tool). See packages/mcp/README.md for per-client setup.
