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 | $0.12170 | $0.12170 |
| Opus 5.5 | $0.04868 | $0.04868 |
| Sonnet 5.5 | $0.02434 | $0.02434 |
| Haiku 4.5 | $0.01217 | $0.01217 |
Grade A, and why
Stuff 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 2d 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 — 786 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Stuff – Repository Shape
This file is the repo-wide contract. It covers the build system, Swift conventions, and how to work with branches, commits, PRs, and CI. Every module also carries its own AGENTS.md. That file covers scope, layering, and invariants. Read this file first. Then read each descendant AGENTS.md that applies to the affected paths, including source-directory files. These files complement each other.
Roughly, this file covers:
- Building and testing — Build system, Formatting, Targets, Deployment, Generating the Xcode project, Running tests, and the Linux/Cloud caveats.
- Writing code — Per-module docs (and the module layout),
Repo-level docs, and Conventions
(including Modeling state and
Composition). Load the
building-uiskill for SwiftUI/UIKit construction, Broadway styling, accessibility, previews, and snapshots. - Working — Working in this repo: commits. GitHub and running tests load their skills when needed.
Build system
| Tool | Pinned via |
|---|---|
| Tuist | .mise.toml |
| SwiftFormat | .mise.toml |
| ShellCheck | .mise.toml |
| Ruby | .mise.toml |
| Fastlane and Ruby dependencies | Gemfile.lock |
| Node.js | .mise.toml |
| Astro and TypeScript | package-lock.json |
| Swift PM | Package.swift (swift-tools-version) |
| Bumper Bowling | Package.swift / Package.resolved |
| Xcode snapshot renderer | .xcode-build-version |
Read the exact pinned versions from those files. Do not trust a copy in prose. A version in a doc goes stale without notice.
Library targets live in the root Package.swift (one local
package). Apps, app extensions, and test bundles are Tuist targets in
Project.swift (plus Tuist.swift). That file
references the package via Package.local(path: .relativeToRoot(".")). The
two manifests are the authoritative target catalog. This file does not duplicate that catalog.
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.

Stuff AGENTS.md is an instructions file published in the GitHub repository kyleve/Stuff (4 stars, last pushed today), licensed Apache-2.0. It adds 12,170 tokens to every session, about $0.0487 per session on Opus 5.5. 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 2026-08-31.
