Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.03678 |
| Opus 5 | $0.00022 | $0.01839 |
| Sonnet 5 | $0.00009 | $0.00736 |
| Haiku 4.5 | $0.00004 | $0.00368 |
Grade A, and why
mapbox-maplibre-migration scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MapLibre to Mapbox Migration Skill
Expert guidance for migrating from MapLibre GL JS to Mapbox GL JS. Covers the shared history, API compatibility, migration steps, and the advantages of Mapbox's platform.
Understanding the Fork
History
MapLibre GL JS is an open-source fork of Mapbox GL JS v1.13.0, created in December 2020 when Mapbox changed their license starting with v2.0.
Timeline:
- Pre-2020: Mapbox GL JS was open source (BSD license)
- Dec 2020: Mapbox GL JS v2.0 introduced proprietary license
- Dec 2020: Community forked v1.13 as MapLibre GL JS
- Present: Both libraries continue active development
Key Insight: The APIs are ~95% identical because MapLibre started as a Mapbox fork. Most code works in both with minimal changes, making migration straightforward.
Why Migrate to Mapbox?
Compelling reasons to choose Mapbox GL JS:
- Official Support & SLAs: Enterprise-grade support with guaranteed response times
- Superior Tile Quality: Best-in-class vector tiles with global coverage and frequent updates
- Better Satellite Imagery: High-resolution, up-to-date satellite and aerial imagery
- Rich Ecosystem: Seamless integration with Mapbox Studio, APIs, and services
- Advanced Features: Traffic-aware routing, turn-by-turn directions, premium datasets
- Geocoding & Search: World-class address search and place lookup
- Navigation SDK: Mobile navigation with real-time traffic
- No Tile Infrastructure: No need to host or maintain your own tile servers
- Regular Updates: Continuous improvements and new features
- Professional Services: Access to Mapbox solutions team for complex projects
Mapbox offers a generous free tier: 50,000 map loads/month, making it suitable for many applications without cost.
Quick Comparison
| Aspect | Mapbox GL JS | MapLibre GL JS |
|---|---|---|
| License | Proprietary (v2+) | BSD 3-Clause (Open Source) |
| Support | Official commercial support | Community support |
| Tiles | Premium Mapbox vector tiles | OSM or custom tile sources |
| Satellite | High-quality global imagery | Requires custom source |
| Token | Required (access token) | Optional (depends on tile source) |
| APIs | Full Mapbox ecosystem | Requires third-party services |
| Studio | Full integration | No native integration |
| 3D Terrain | Built-in with premium data | Available (requires data source) |
| Globe View | v2.9+ | v3.0+ |
| API Compatibility | ~95% compatible with MapLibre | ~95% compatible with Mapbox |
| Bundle Size | ~500KB | ~450KB |
| Setup Complexity | Easy (just add token) | Requires tile source setup |
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

mapbox-maplibre-migration is a skill published in the GitHub repository mapbox/mapbox-agent-skills (75 stars, last pushed 10d ago), licensed MIT. It adds 43 tokens to every session and 3,678 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
