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 | $0.00053 | $0.01755 |
| Opus 5 | $0.00026 | $0.00877 |
| Sonnet 5 | $0.00011 | $0.00351 |
| Haiku 4.5 | $0.00005 | $0.00176 |
Grade A, and why
mapbox-style-patterns 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 3d 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.
How it starts

Mapbox Style Patterns Skill
This skill provides battle-tested style patterns and layer configurations for common mapping scenarios.
Pattern Library
Pattern 1: Restaurant/POI Finder
Use case: Consumer app showing restaurants, cafes, bars, or other points of interest
Visual requirements:
- POIs must be immediately visible
- Street context for navigation
- Neutral background (photos/content overlay)
- Mobile-optimized
Recommended layers:

What ships with it
9 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-style-patterns is a skill published in the GitHub repository mapbox/mapbox-agent-skills (74 stars, last pushed 8d ago), licensed MIT. It adds 53 tokens to every session and 1,755 once invoked, about $0.0003 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.
