At a glance

A skill your agent uses when working on Sake configuration — .sake.yml, environment variables, CLI options, ConfigManager, ConfigResolver, or adding new config options.

  • Working on Sake configuration — .sake.yml
  • SKILL.md covers Resolution Cascade, Config Types, Available Options and .sake.yml Format, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Environment variables

What it does

Sake Config System is an agent skill from kattouf/Sake. Use when working on Sake configuration — .sake.yml, environment variables, CLI options, ConfigManager, ConfigResolver, or adding new config options.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Bash. The repository describes itself as: 🍶 Swift-based utility for managing project commands, inspired by Make. The licence is MIT.

When your agent uses it

  • Working on Sake configuration — .sake.yml
  • Environment variables
  • Adding new config options

Example prompts

  • “/sake-config-system”

What it can do on your machine

Read from SKILL.md and the folder at commit 80a3e98. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are swift and yaml).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sake Config System loads about 687 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 82 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~687

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Sake Configuration System

Resolution Cascade

Priority (highest first): CLI args → ENV vars → .sake.yml → defaults

Config Types

CLIConfig         → from ArgumentParser options (CommonOptions, CommandRelatedCommonOptions)
ENVConfig         → from ProcessInfo.processInfo.environment
FileConfig        → from .sake.yml via Yams
Config            → resolved final config
ConfigResolver    → merge logic
ConfigManager     → orchestrates loading + resolution

Available Options

OptionCLIENV.sake.ymlDefault
Config path--config-pathSAKE_CONFIG_PATH—.sake.yml
SakeApp path--sake-app-pathSAKE_APP_PATHsake_app_path./SakeApp
Prebuilt binary--sake-app-prebuilt-binary-pathSAKE_APP_PREBUILT_BINARY_PATHsake_app_prebuilt_binary_pathnil
Case strategy--case-converting-strategySAKE_CASE_CONVERTING_STRATEGYcase_converting_strategykeepOriginal
Experimental—SAKE_EXPERIMENTAL_FEATURES—disabled

Mutual exclusion: sakeAppPath and sakeAppPrebuiltBinaryPath cannot both be set.

.sake.yml Format

yaml
case_converting_strategy: toSnakeCase  # keepOriginal | toSnakeCase | toKebabCase
sake_app_path: SakeApp
sake_app_prebuilt_binary_path: .build/prebuilt/SakeApp

Parsed with Yams library. FileConfig is Decodable.

Case Converting Strategies

swift
enum CaseConvertingStrategy: String, CaseIterable, ExpressibleByArgument, Decodable, Sendable {
    case keepOriginal   // helloWorld → helloWorld
    case toSnakeCase    // helloWorld → hello_world
    case toKebabCase    // helloWorld → hello-world
}

Applied by CommandNameCaseConverter to command names when listing/running.

Error Handling

swift
ConfigManager.Error:
  .configFileNotFound(configPath:)
  .configFileCorrupted(configPath:, error:)

ConfigResolver.Error:
  .mutualExclusiveOptions(["sakeAppPath", "sakeAppPrebuiltBinaryPath"])
