official mise documentation environment-specific mise.<environment>.toml files -E MISE_ENV
💡 Result:
Mise supports environment-specific configuration files using the MISE_ENV environment variable [1][2][3]. When MISE_ENV is set to a specific value (e.g., development or production), mise automatically looks for configuration files with that suffix in the current and parent directories [1]. How it works: 1. Setting MISE_ENV: You can set the MISE_ENV environment variable via your shell, a CLI flag (e.g., --env development), or within a.miserc.toml file for persistent configuration [1]. 2. File Discovery: When MISE_ENV is active, mise searches for files such as mise.{MISE_ENV}.toml or.mise.{MISE_ENV}.toml [1][2]. 3. Multiple Environments: You can specify multiple environments by separating them with commas (e.g., MISE_ENV=ci,test), in which case they are read in the specified order, with the last one taking precedence [4][5]. 4. Precedence: These environment-specific files are integrated into the standard configuration loading hierarchy, allowing them to override broader configuration files like standard mise.toml files [1][2][3]. Note: MISE_ENV itself cannot be defined within a mise.toml file because it determines which configuration files to load before the file is parsed [1]. Additionally, mise also supports environment-specific "local" files (e.g., mise.{MISE_ENV}.local.toml) intended for machine-specific overrides that should not be committed to version control [1].

Select the agent environment when running setup:agent
mise.agent.toml defines setup:agent, but the repository has no tracked invocation that sets MISE_ENV=agent. A plain mise run setup:agent can therefore omit this task. Add MISE_ENV=agent mise run setup:agent to the setup documentation or automation.

💡 Result:
To sign Git commits using an SSH key managed by ssh-agent, you must configure Git to use the SSH signing format. While official Git configuration documentation focuses primarily on core settings, the standard workflow for enabling SSH commit signing involves setting the following configurations [1][2]. First, set the GPG format to ssh: git config --global gpg.format ssh Next, specify the public key to be used for signing. The user.signingKey value should be the public SSH key content or a path to it (typically ending in.pub). Git will utilize ssh-agent to handle the private key automatically when a commit is signed [1][2]: git config --global user.signingKey /path/to/your/public-key.pub To enable signing for all commits automatically, you can also set the following: git config --global commit.gpgSign true Because your private key is managed by ssh-agent, you do not need to configure the private key path directly in Git; ensure your SSH key is added to the agent using ssh-add before attempting to sign commits [3][4].

Load the signing key into an SSH agent before enabling SSH signing.
setup:agent writes the private key and configures user.signingkey with the public-key path, but it never runs ssh-add. With signing enabled for all commits and tags, Git can fail to sign in a clean environment. Ensure a persistent SSH agent is available and run ssh-add "$SIGNING_PRIVATE_KEY" before Git operations. Keep user.signingkey set to "$SIGNING_PUBLIC_KEY".

mise lockfile_platforms locked true current platform lock data official documentation
💡 Result:
In mise, lockfile_platforms and locked=true are distinct configuration settings that serve different purposes regarding lockfile management [1][2][3]. lockfile_platforms The lockfile_platforms setting restricts which platforms are included when generating or updating lockfile data (e.g., during mise install, mise use, or mise lock) [1][4][5]. - Behavior: By default, if left unset, mise targets all common platforms plus your current platform [1][6]. Setting this option reduces the number of platforms resolved, resulting in smaller lockfiles and faster execution [1][5]. - Important Note: The current platform is always included in the target set, regardless of what is configured in lockfile_platforms [1][6][4]. - Configuration: It is a list of strings (e.g., ["macos-arm64", "linux-x64"]) [1][5] or an environment variable (MISE_LOCKFILE_PLATFORMS, comma-separated) [1][4]. - Overrides: Explicit mise lock --platform flags take precedence and will override this setting [1][4][5]. locked=true The locked setting (also known as "Strict Lockfile Mode") ensures that all tools have pre-resolved URLs in the lockfile for the current platform before installation [7][3]. - Behavior: When locked = true is enabled, mise install will fail if a tool does not have a URL for the current platform already present in the lockfile [2][3]. This prevents external API calls (e.g., to GitHub or registries) during installation, ensuring a fully reproducible environment [7][3]. - Activation: It can be enabled in the configuration file ([settings] locked = true) or via the environment variable MISE_LOCKED=1 [7][3]. In summary, lockfile_platforms manages which platforms' data you choose to maintain in your lockfile to optimize performance and size [1][5], while locked=true enforces strict reproducibility by requiring that the current platform's installation data is already pinned [2][3].

site:mise.jdx.dev/configuration/settings.html lockfile_platforms locked tool_config mise.toml
💡 Result:
In mise, the lockfile_platforms setting is used to restrict which platforms are included when auto-locking or running the mise lock command [1]. When defined, this setting helps keep lockfiles smaller and improves the performance of operations like mise install or mise use by avoiding the resolution of checksums and URLs for unnecessary platforms [1]. This configuration is defined within the [settings] table of your mise.toml file [1]. You can specify one or more platforms using the os-arch or os-arch-qualifier format (e.g., linux-x64, linux-x64-musl, macos-arm64) [1]. Example configuration in mise.toml: [settings] lockfile_platforms = ["macos-arm64", "linux-x64"] Key details regarding this setting include: - It can also be configured via the MISE_LOCKFILE_PLATFORMS environment variable (comma-separated) [1]. - If left unset, mise defaults to targeting all common platforms (such as linux-x64, linux-x64-musl, linux-arm64, linux-arm64-musl, macos-x64, macos-arm64, and windows-x64) in addition to the current platform [1]. - The current platform is always included in the lockfile, regardless of this setting [1]. - This setting does not override explicit --platform flags used with the mise lock command [1].

💡 Result:
In mise, [tool_config] locked = true is a configuration policy used to enforce reproducible tool installations by requiring that tools be resolved and installed from a lockfile [1][2]. When this setting is enabled in your mise.toml file, mise will fail during installation if the required tools do not have pre-resolved versions and asset information recorded in the corresponding lockfile (e.g., mise.lock) [1][3][4]. This ensures that your project uses identical tool versions and binaries across different environments, preventing reliance on external API lookups (like GitHub) during installation [3][4]. Key details regarding this configuration: Scope: The [tool_config] section applies specifically to tools declared within the same configuration root (e.g., in mise.toml and mise.local.toml) [1][4]. It does not override or affect tool policies inherited from global or parent configuration files [1][4]. Lockfiles: To use locked mode, you must have a lockfile present [3]. If you do not have one, you can create an empty file (e.g., touch mise.lock) and run mise install to populate it [5]. Comparison with global settings: While you can set locked = true in global settings, that applies to all tool resolution invocation-wide [3][4]. Using [tool_config] locked = true is the recommended way to enforce strict, reproducible mode only for a specific project's tools [4].

Add lockfile entries for all supported platforms.
mise.lock contains entries only for linux-x64. The repository supports macos-arm64, macos-x64, and windows-x64. With [tool_config] locked = true, mise install on those platforms can fail because the lockfile lacks current-platform tool URLs. Add the missing entries or document Linux-only mise setup.
