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 | $0.00000 | $0.27928 |
| Opus 5.5 | $0.00000 | $0.11171 |
| Sonnet 5.5 | $0.00000 | $0.05586 |
| Haiku 4.5 | $0.00000 | $0.02793 |
Grade A, and why
swift6-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 1mo 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
The opening of the file, as written. The whole thing — 4,049 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Building
Run docc preview Guide.docc in this repository's root directory.
After running DocC,
open the link that docc outputs to display a local preview in your browser.
Note:
If you installed DocC by downloading a toolchain from Swift.org,
doccis located inusr/bin/, relative to the installation path of the toolchain. Make sure your shell'sPATHenvironment variable includes that directory.If you installed DocC by downloading Xcode, use
xcrun doccinstead.
================================================ FILE: CODEOWNERS
Lines starting with '#' are comments.
Each line is a case-sensitive file pattern followed by one or more owners.
Order is important. The last matching pattern has the most precedence.
More information: https://docs.github.com/en/articles/about-code-owners
Please mirror the repository's file hierarchy in case-sensitive lexicographic
order.

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.

swift6-migration is a cursor rule published in the GitHub repository steipete/agent-rules (5,677 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 27,928 tokens. 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.
