Mise

mise

Patterns for writing and maintaining mise.toml files based on the mise-lib-template and nv-gcp-template conventions used across projects.

The raw invocation args, if this skill was slash-invoked (e.g. /mise <topic>): $ARGUMENTS. If this line is not filled in, read any question from the user's current message and answer from the recipes below.

Markdown output: soft-wrap prose, never hard-wrap — when writing markdown, write each paragraph as one continuous line; do not insert manual newlines to wrap prose at a fixed column width. Newlines still separate paragraphs, list items, headings, and code fences.

When to load recipes

mise.toml Structure

Standard section order:

# [env] — environment variables (PROJECT, VERSION, GCP_*, PATH extensions)
# [tools] — tool versions (node, pnpm, gcloud, etc.)
# [tasks.*] — inline tasks grouped by: CORE, DOCKER, CI/CD, UTILITIES
# [task_config] includes = ["mise-tasks"]  ← for external task dirs
# [settings] experimental = true  ← required for some features

Environment Variables

[env]
PROJECT                 = "my-project"
VERSION                 = "{{ exec(command='cat version.txt 2>/dev/null | tr -d [:space:] || echo 0.1.0') }}"
GCP_REGISTRY_PROJECT_ID = "devops-466002"
GCP_REGISTRY_REGION     = "us-east1"
GCP_REGISTRY_NAME       = "cloudvoyant-generic-registry"
_.path                  = ['{{ config_root }}/node_modules/.bin']  # extend PATH

Key patterns:

• VERSION always read from version.txt with a fallback
• _.path extends $PATH — use config_root not hardcoded paths
• GCP vars follow: GCP_REGISTRY_* (artifact registry) and GCP_PROJECT_* / GCP_DEVOPS_* (project split)

Tools

[tools]
node       = "lts"       # or "20", "24"
pnpm       = "latest"    # or "10"
gcloud     = "latest"
terraform  = "1"         # major-pinned
shellcheck = "latest"
shfmt      = "latest"
bats       = "latest"
claude     = "latest"

• Pin to major version for infra tools (terraform = "1")
• Use "lts" for node unless a specific version is needed
• Add npm:package-name to install npm packages as tools: "npm:skills-ref" = "0.1.5"

Task Patterns

Inline tasks (preferred for ≤20 tasks)

[tasks.build]
description = "Build the project"
depends     = ["install"]
run         = "pnpm build"

[tasks.test]
description = "Run tests"
depends     = ["build"]
run         = "pnpm test"

[tasks."format-check"]
description = "Check formatting"
run         = "shfmt -d .mise-tasks/"

External task dir (preferred for large projects)

[task_config]
includes = ["mise-tasks"]

[settings]
experimental = true  # required for task_config.includes

Scripts in mise-tasks/ are auto-discovered. Hide internal helpers:

#!/usr/bin/env bash
#MISE hide=true

Standard task set (every project should have these)

Docker tasks (when applicable)

[tasks.docker-build]
description = "Build Docker image"
run         = "COMPOSE_BAKE=true docker compose build"

[tasks.docker-run]
description = "Run in Docker"
depends     = ["docker-build"]
run         = "docker compose up"

[tasks.docker-test]
description = "Run tests in Docker"
depends     = ["docker-build"]
run         = "docker compose run --rm app mise run test"

GCP publish pattern (from mise-lib-template)

[tasks.publish]
description = "Publish to GCP Artifact Registry"
depends     = ["test", "build-prod"]
run         = """
IMAGE="${GCP_REGISTRY_REGION}-docker.pkg.dev/${GCP_REGISTRY_PROJECT_ID}/${GCP_REGISTRY_NAME}/${PROJECT}:${VERSION}"
docker build -t "$IMAGE" .
docker push "$IMAGE"
echo "Published: $IMAGE"
"""

[tasks.publish-rc]
description = "Publish release candidate"
depends     = ["test", "build-prod"]
run         = """
IMAGE="${GCP_REGISTRY_REGION}-docker.pkg.dev/${GCP_REGISTRY_PROJECT_ID}/${GCP_REGISTRY_NAME}/${PROJECT}:${VERSION}-rc"
docker build -t "$IMAGE" .
docker push "$IMAGE"
"""

Monorepo Pattern (pnpm workspaces)

[tasks."build:web"]
run = "pnpm --filter @myproject/web run build"

[tasks."test:api"]
run = "pnpm --filter @myproject/api run test"

Common Pitfalls

• config_root vs $PWD: use {{ config_root }} in TOML templates, $MISE_CONFIG_ROOT in bash tasks
• experimental = true: required for [task_config] includes and some env features — add it
• Task names with hyphens: wrap in quotes: [tasks."build-prod"]
• Depends chain: depends = ["install"] runs before the task; don't duplicate in run
• PATH not extended?: use _.path = [...] not PATH = "..." — the latter overwrites

Version Management

version.txt holds the current semver. The upversion task runs semantic-release:

[tasks.upversion]
description = "Bump version based on conventional commits"
run         = ".mise-tasks/upversion"

Publish tasks should depend on the version being set, not bump it themselves.
