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 | $0.00029 | $0.02246 |
| Opus 5 | $0.00015 | $0.01123 |
| Sonnet 5 | $0.00006 | $0.00449 |
| Haiku 4.5 | $0.00003 | $0.00225 |
Grade C, and why
mise scanned grade C with 2 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 10d 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.

mise - Development Environment Management
This skill activates when working with mise for managing tool versions, environment variables, and project tasks.
What is mise?
Current stable: v2026.3.15
mise is a polyglot runtime manager and development environment tool that combines:
- Tool version management - Install and manage multiple versions of dev tools
- Environment configuration - Set environment variables per project
- Task automation - Define and run project tasks
- Cross-platform - Works on macOS, Linux, and Windows
Install with curl https://mise.run | sh (or brew install mise), then activate in the shell: eval "$(mise activate zsh)". Full install matrix, shims, IDE and CI/CD integration: references/setup-and-troubleshooting.md.
Tool Backends
mise uses different backends (package managers) to install tools:
- asdf - Traditional asdf plugins (default for many tools)
- github - GitHub release-asset installer (replaces deprecated ubi backend)
- cargo - Rust packages (requires Rust installed)
- npm - Node.js packages (requires Node installed)
- go - Go packages (requires Go installed)
- aqua - Package manager
- pipx - Python packages (requires Python installed)
- gem - Ruby packages (requires Ruby installed)
- gitlab - Direct from GitLab repositories
- http - Direct HTTP downloads
Prefer registry short names (ripgrep) over backend-prefixed forms (cargo:ripgrep) when the tool is in the mise registry (mise registry | grep <tool-name>). Fall back to an explicit backend prefix when the registry has no entry.
Per-backend detail — github backend options (exe, asset_pattern, extract_all, rename_exe), multi-arch platform keys, cargo prerequisites and git installs, upgrades and aliases: references/backends.md.
Verify Before Pinning — ls-remote
mise ls-remote <backend>:<target> returns all available versions for any backend. Run this BEFORE pinning a version in mise.toml to confirm the backend can actually see the tool:
What ships with it
7 files 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.

mise is a skill published in the GitHub repository vinnie357/claude-skills (25 stars, last pushed yesterday), licensed MIT. It adds 29 tokens to every session and 2,246 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
