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 | $0.01023 | $0.01023 |
| Opus 5.5 | $0.00409 | $0.00409 |
| Sonnet 5.5 | $0.00205 | $0.00205 |
| Haiku 4.5 | $0.00102 | $0.00102 |
Grade A, and why
build-swift-apps AGENTS.md 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.

Agent Guidance
This repository is a multi-agent skill pack for Swift and Apple-platform development. It should stay generic, public-safe, and useful across Codex, Claude Code, Cursor, pi, and manual skill installs.
Project Shape
skills/contains installable Agent Skills. Each directory must contain oneSKILL.mdentrypoint and any local scripts or references that skill needs.shared/contains canonical support files used by multiple skills. Link to shared files instead of duplicating long guidance.references/contains plugin-level audits, ledgers, and routing notes that should not live in hot skill files.commands/contains short command entrypoints that delegate to canonical skills..codex-plugin/,.claude-plugin/,.cursor-plugin/,agents/, andpackage.jsonare packaging surfaces for different agents. Keep them in sync when skills are added or removed.docs/INSTALL.mdis the user-facing installation and dependency guide.scripts/doctor.sh,scripts/install-deps.sh, andscripts/validate-package.share the operational checks for new machines and release hygiene.
Scope
The plugin is for Swift application development across Apple platforms, with the deepest coverage for iOS and macOS. Do not add private/internal workflows, private service names, project names, or credentials. Keep examples generic and reusable.

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.

build-swift-apps AGENTS.md is an instructions file published in the GitHub repository Xopoko/build-swift-apps (45 stars, last pushed 1mo ago), licensed MIT. It adds 1,023 tokens to every session, about $0.0041 per session on Opus 5.5. A static security scan graded it A with 0 findings.
