mise

mise is a skill for Claude Code, Codex from fmind/dot. It costs 20 tokens per session (1,106 once invoked), scanned A, original, MIT.

A guide to configuring mise, a tool that pins development tools and defines reusable project commands. These commands cover tasks such as installing dependencies, formatting, checking, testing, building, and watching.

In plain words
What is it for?
Use it to create or update mise.toml and standardize the project’s development task vocabulary.
Why use it?
It gives developers, Git hooks, and CI one shared set of commands, reducing differences between local and automated checks.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

mise 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 today.

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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mise

One project mise.toml owns tool pins and commands; hooks and CI decide when to invoke them. Reuse the appropriate language stack's configuration instead of creating parallel command definitions.

Workflow

  1. Inspect the repository's existing tasks, lockfile, tool providers, hooks, and CI before changing the contract.
  2. Select versions per the tool version rules before installing copied scaffold selectors: fmind/dot tracks latest; a documented hold (currently Python 3.14) carries its reason beside the pin; every other repository owns exact pins and changes them only during its own requested upgrade. Seed a new project from installed versions (mise ls --installed --json) to reuse installations; never copy tool binaries into projects.
  3. Keep tasks simple: prefer direct commands, short sequential run arrays, and declarative dependencies. A short multiline sequence for setup and cleanup is acceptable; avoid explicit bash -c/sh -c, nested conditions, argument-dispatch wrappers, and large shell programs. Use native tool options or explicit task names first; put necessary procedural logic in a small maintained script, preferably Python.
  4. Keep the shared vocabulary below; read task conventions for subtask names, concise output, argument forwarding, dependency order, and tool updates.
  5. Pin and install the project toolchain, then validate task definitions with mise tasks validate; use mise run <task> in automation.
  6. Verify the changed task and its callers, then the required complete gate; record a concrete reason for held-back pins.

Task Vocabulary

Every project exposes the same core tasks with short aliases so agents, hooks, and CI stay portable:

Task Alias Purpose
install i Sync dependencies and install git hooks (lefthook install).
format f Format all sources (fans out to format:*).
check c All static checks in parallel (fans out to check:*).
test t Run the test suite.
build b Compile or package artifacts (fans out to build:*).
watch w Live reload, or re-run tests; omitted by stacks with neither.
all a format, check, test, build in sequence: the full gate.

What ships with it

3 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 fmind/dot (12 stars, last pushed today), licensed MIT. It adds 20 tokens to every session and 1,106 once invoked, about $0.0001 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 2026-09-03.
