Is the Portaljs Add Geo skill free?

Yes. The skill itself is free from datopian/portaljs. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Portaljs Add Geo SkillProof Score?

7.6/10 — installs cleanly 4/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.

How do I install Portaljs Add Geo?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Portaljs Add Geo with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 7.6/10
Tested: Jul 20, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · ef05442

Fetched the repo tree (14 portaljs SKILL.md files), read SKILL.md, the referenced workflow .claude/commands/portaljs-add-geo.md, and references/reference.md in full — both referenced files exist. Frontmatter parses cleanly with name/description; grep for base64/curl|sh/exfil/webhooks came back clean (the Arc JWT + R2/Giftless push is legitimate Datopian infra). The workflow is detailed and honest — hard-stops on missing tools, documents a >2GB PMTiles-skip degradation and Windows-WSL limitation rather than hiding them. OUTPUT is NOT measured (not a measured loss): the skill shells out to native GDAL/tippecanoe/duckdb and needs a scaffolded portal plus R2 credentials, none installable under the safety rules, so I scored output 5 as unmeasured-neutral. Install docked one point because copied files are inert without those external CLIs.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 4/5
Triggers reliably 5/5

What Portaljs Add Geo does

Auto-ingests a vector geospatial file (GeoJSON, zipped Shapefile, GeoPackage, KML/KMZ, FlatGeobuf, CSV-with-geometry) into a PortalJS portal: normalizes CRS to EPSG:4326, derives a PMTiles render tier and a GeoParquet query tier, pushes all three artifacts to Cloudflare R2 via Git LFS, and appends one dual-tier datasets.json entry the showcase auto-renders. Triggers when the source is a vector geo format that needs a map or spatial-query view; it explicitly defers plain tabular data to portaljs-add-dataset and small-Leaflet views to portaljs-add-map.

How to install Portaljs Add Geo

Copy skills/portaljs-add-geo/ into your project's .claude/skills/ (and the workflow file .claude/commands/portaljs-add-geo.md), or use the PortalJS plugin. Requires a scaffolded portaljs-catalog portal (PR #1647+ with MapPreview.tsx/GeoQuery.tsx), native GDAL + tippecanoe + duckdb (macOS: brew install gdal tippecanoe duckdb; Debian/Ubuntu equivalent; Windows via WSL), and Arc credentials (or self-hosted Giftless) for the Git-LFS to R2 push.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Portaljs Add Geo

/portaljs-add-geo Ingest a geo file into a serverless PortalJS portal as PMTiles + GeoParquet tiers

It also activates on plain-language prompts like these:

Add this Shapefile as a map layer to the portal
Ingest this GeoPackage and generate PMTiles
Import this KML file with spatial query support
