Narrative Skills Marketplace

Narrative Skills Marketplace

An agent skills marketplace from Narrative I/O.

Interactive, AI-powered workflows that walk you through the recurring work of a modern data company — mapping schemas, writing NQL, qualifying leads, shipping code, building decks — one approval at a time.

What is this?

A marketplace of agent skills. Each plugin bundles one or more skills — interactive slash commands like /write-nql or /generate-rosetta-stone-mappings that turn a recurring task into a guided, AI-augmented workflow.

Install the marketplace, type a slash command in your agent, and the skill takes it from there: it asks the right questions, does the research, drafts the artifact, and waits for your approval before acting on anything outside your repo.

Skills follow the Agent Skills spec and run in any spec-compliant harness. The bundled bash setup installer has two modes: a Claude Code path (uses the claude CLI to register the marketplace) and a --portable path that builds a dist/ tree any agentskills.io-compliant harness can consume — see [Install on other harnesses](#install-on-other-harnesses).

Every rendered SKILL.md is committed; CI fails if any rendered file is stale relative to its .tmpl. Other harnesses can clone this repo (or read from raw.githubusercontent.com) without running Bun.

Quick install (any agent)

The fastest path — no clone, no Bun. The skills CLI reads the skills straight from this repo and installs them into your agent's skills directory:

npx skills add narrative-io/narrative-skills-marketplace

It discovers all the skills (it walks the plugins//skills/ layout for you), auto-detects the agent it's running under, and installs into the current project by default. Useful flags:

npx skills add narrative-io/narrative-skills-marketplace --list        # preview skills, install nothing
npx skills add narrative-io/narrative-skills-marketplace -g            # install globally (user-level)
npx skills add narrative-io/narrative-skills-marketplace -a claude-code cursor   # target specific agents
npx skills add narrative-io/narrative-skills-marketplace --all         # all skills, all detected agents, no prompts

This installs the rendered SKILL.md files only. Skills that call the narrative-mcp server still need that MCP server registered separately (see [mcp/](mcp/) and [Install on other harnesses](#install-on-other-harnesses)). For the full Claude Code marketplace experience (plugin grouping + bundled MCP config), use bash setup below.

Install on Claude Code

git clone https://github.com/narrative-io/narrative-skills-marketplace
cd narrative-skills-marketplace
bash setup

setup registers the marketplace, installs every plugin listed below, and regenerates the catalog in this README.

Requirements

• Claude Code CLI on PATH
• Bun ≥ 1.1 (used for template rendering + scripts)

Install on other harnesses

The skills are spec-portable. Each plugins//skills// directory is a self-contained Agent Skill (rendered SKILL.md plus any references/ / scripts/ / assets/). The discovery index lives at [skills.json](skills.json); MCP server configs live under [mcp/](mcp/).

To build a flat, plugin-namespace-free distribution at dist/:

bash setup --portable      # or: bun run build:portable

This emits dist/skills// (one folder per skill, no plugin nesting), dist/mcp/*.mcp.json, and dist/skills.json. Then:

| Harness | How to install | |---------|----------------| | Any skills-aware agent | npx skills add narrative-io/narrative-skills-marketplace — see [Quick install](#quick-install-any-agent). No clone or Bun required. | | Claude Code | Use the default bash setup (registers the marketplace). | | Claude.ai web Skills | Zip each dist/skills// directory and upload it under Settings → Capabilities → Skills. | | Claude Desktop (Mac) | cp -R dist/skills/* "$HOME/Library/Application Support/Claude/skills/", then merge [mcp/all.mcp.json](mcp/all.mcp.json) into claude_desktop_config.json. | | Claude Desktop (Windows) | cp -R dist/skills/* "$APPDATA/Claude/skills/", then merge mcp/all.mcp.json into claude_desktop_config.json. | | Cursor | Copy dist/skills/*/SKILL.md into .cursor/rules/ in your project. MCP servers go in ~/.cursor/mcp.json (paste from mcp/all.mcp.json). | | Generic MCP-aware agent | Point the agent at dist/skills/ as its skills root and register the servers in mcp/all.mcp.json via your harness's MCP config. |

One Claude-Code-specific dependency: the skills currently use AskUserQuestion (a Claude Code primitive) for interactive prompts. It's declared in compatibility.recommends.tools, not requires, so spec-compliant harnesses without it should fall through to the documented prose Q&A fallback in each skill's ## Harness fallbacks section.

Plugins

narrative-common

Common Narrative workflows backed by the narrative-mcp server — starting with Rosetta Stone attribute mapping generation, evaluation, and improvement.

| Skill | Use when | |-------|----------| | /apply-rosetta-stone-mappings | "apply these mappings to dataset N", "create the Rosetta Stone mappings I just generated", "push the mappings I saved earlier to ", "productionize this mapping list", "submit the suggestedmappings array". | | /create-workflow | "create a workflow that does X", "schedule a daily refresh of dataset Y", "wrap this NQL as a workflow", "build a pipeline that creates view A then refreshes view B", "submit this workflow YAML", "productionize this query as a recurring job". | | /design-analysis | "why did X drop", "is there a relationship between A and B", "who are our highest-value customers", "what's driving the change in Y", "investigate this trend", "design an analysis for", "scope this analytical question". | | /find-attribute | "find the X attribute", "what's the graph-edge attribute ID", "look up the email Rosetta Stone attribute", "search the attribute catalog for Y", "which attribute has SOURCEID + TARGETID + ISDIRECTED". | | /generate-rosetta-stone-mappings | "map this dataset to Rosetta Stone", "suggest normalized attributes for dataset N", "evaluate the mappings on dataset N", "why is this mapping low confidence", "fix this expression", "improve this NQL mapping expression". | | /profile-dataset | "profile dataset N", "what does dataset N look like", "coverage and quality of ", "what id types does N emit", "null rates / cardinality for ", "is this dataset's stats fresh". | | /write-nql | "write an NQL query for X", "query this dataset", "validate this NQL", "run NQL against dataset ", "how many rows match Y", "show me the top N records from ". |

narrative-identity

Identity-graph workflows backed by the narrative-mcp server — pre-graph data-quality auditing, edge-quality analysis, and graph-build hygiene.

| Skill | Use when | |-------|----------| | /generate-identity-graph | "build an identity graph", "generate an identity graph", "create an identity graph", "stitch these datasets into a graph", "make a graph workflow", "label connected components on these datasets", "I want a person graph / household graph / device graph". | | /generate-match-report | "how does my data compare to your marketplace", "compare my data to [partner]", "how much overlap do I have with [supplier]", "run a match report", "match my customers against 3P data", "see what enrichment is available for my dataset", or any open-ended question about marketplace overlap. | | /triage-pregraph-data | "audit this dataset before the graph build", "find bad edges in ", "check identity data quality", "recommend filters for the graph build", "quantify damage from ", "pre-graph DQ". |

narrative-audience

Audience-building workflows backed by the narrative-mcp server — turning marketing briefs into filtered, materialized audience datasets and activating them to downstream advertising connectors.

| Skill | Use when | |-------|----------| | /create-lookalike | "create a lookalike audience", "find more users like this segment", "expand my seed audience to 500k similar users", "score the population against my customers", "build a look-alike of dataset X". |

What's a skill?

A skill is a single SKILL.md file with YAML frontmatter and a numbered, phased workflow. The frontmatter declares what tools the skill can call; the body walks the user through the work, one question at a time, drafting artifacts and waiting for approval at each gate.

## Phase 1. Pin the dataset

…

Some skills reuse boilerplate via the snippet system — author a SKILL.md.tmpl with {{SNIPPET:pin-company-context}} and bun run gen:skill-docs renders the final SKILL.md. See [AGENTS.md → Template system](AGENTS.md#template-system).

Development

bun install                  # install dev deps (Biome, Knip, TS)
bun run gen:skill-docs       # render SKILL.md from SKILL.md.tmpl files
bun run check                # Biome — format + lint
bun run check:fix            # Biome — autofix everything safe
bun run typecheck            # tsc --noEmit, strict mode
bun run knip                 # find unused deps / files / exports
bun run check:manifests      # validate marketplace.json + plugin.json + SKILL.md
bun run check:skill-docs     # fail if any SKILL.md is stale vs. its .tmpl
bun run ci                   # everything CI runs, in order

Every check above runs in [CI](.github/workflows/ci.yml) on push and PR — including shellcheck on the setup script. Biome is configured with the strictest practical ruleset (all rule groups + nursery + pedantic style/correctness/ suspicious rules); see [biome.json](biome.json).

Contributing

[docs/authoring-skills.md](docs/authoring-skills.md) is the canonical guide for writing a new skill — frontmatter contract, description writing, phased body structure, progressive disclosure, composing skills, the template / snippet system, and CI checks.

[AGENTS.md](AGENTS.md) is the quick reference for the same material and covers:

• Project structure (plugins//skills//SKILL.md)
• Naming conventions (verb-noun: /triage-lead, /create-deck)
• The SKILL.md format + the 1024-char description cap
• Skill design principles (interactive, drafts-not-actions, etc.)
• The snippet / template system

Pull requests go through the CI gauntlet above; the Plugins catalog in this README regenerates itself from each skill's frontmatter — edit the frontmatter, not the table.
