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 | $0.01272 | $0.01272 |
| Opus 5 | $0.00636 | $0.00636 |
| Sonnet 5 | $0.00254 | $0.00254 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
skills-manager 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 7d 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.

Project Overview
Skills Manager is a desktop application for managing Codex skills and plugins. It's built with Tauri 2 (Rust backend) and React + TypeScript (Vite frontend), targeting macOS and Windows.
The application scans Codex's plugin directories, displays skills in a UI, and enables/disables them by modifying ~/.Codex/settings.json. It also supports cloning GitHub repositories containing custom skills.
Development Commands
Start Development Server
npm run tauri:dev
This starts:
- Vite dev server on http://localhost:5173 (frontend with hot reload)
- Tauri app window
- Rust cargo watch for backend changes
Note: Requires Rust toolchain and OpenSSL. On macOS with Homebrew:
export OPENSSL_DIR=$(brew --prefix openssl@3)
export PKG_CONFIG_PATH=$(brew --prefix openssl@3)/lib/pkgconfig
Build Production Bundle
# macOS
npm run tauri:build --target universal-apple-darwin
# Windows
npm run tauri:build --target x86_64-pc-windows-msvc
Output: src-tauri/target/release/bundle/
Build Rust Only (faster for backend changes)
cargo build --manifest-path=src-tauri/Cargo.toml
Architecture
Tauri IPC Pattern
The app uses Tauri's command system for Rust↔JavaScript communication:
Rust (src-tauri/src/commands/): Define functions with #[tauri::command]
Frontend (app/src/api/tauri.ts): Call via invoke('command_name', { args })
All commands are registered in src-tauri/src/main.rs using tauri::generate_handler!.
Core Modules
| Module | File | Responsibility |
|---|---|---|
| SkillScanner | scanner.rs | Scans ~/.Codex/plugins/cache/ and ~/.Codex/skills-manager/ for skills, parses SKILL.md frontmatter |
| SettingsManager | settings.rs | Reads/writes ~/.Codex/settings.json, manages enabledPlugins field |
| GitHubIntegrator | github.rs | Git operations (clone/pull) using git2 crate |
| Commands | commands/*.rs | Tauri command handlers (skills.rs, github.rs) |
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.

skills-manager AGENTS.md is an instructions file published in the GitHub repository cchao123/skills-manager (120 stars, last pushed 3mo ago), licensed MIT. It adds 1,272 tokens to every session, about $0.0064 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.
