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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00280 |
| Opus 5 | $0.00022 | $0.00140 |
| Sonnet 5 | $0.00009 | $0.00056 |
| Haiku 4.5 | $0.00004 | $0.00028 |
Grade A, and why
mapkit 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.
What it actually says
MapKit Skills
Location and place-data patterns built on MapKit and GeoToolbox.
When This Skill Activates
Use this skill when the user:
- Works with PlaceDescriptor or GeoToolbox
- Needs geocoding or reverse geocoding
- Handles place identifiers across services (Apple Maps + third-party)
Available Skills
Paths are relative to THIS file's directory — skills run with cwd set to the user's project, so resolve each path from this SKILL.md's own location.

How to Route
- Read
geotoolbox/SKILL.md(relative to this file) plus any reference files it lists. - Apply the guidance to the user's code.
What ships with it
1 file 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.

mapkit is a skill published in the GitHub repository rshankras/claude-code-apple-skills (701 stars, last pushed 1mo ago), licensed MIT. It adds 43 tokens to every session and 280 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 2026-09-03.
