// install — copy + paste into any project

mkdir -p .claude/skills && curl -fsSL https://raw.githubusercontent.com/majesticlabs-dev/majestic-marketplace/HEAD/plugins/majestic-engineer/skills/config-reader/SKILL.md -o .claude/skills/config-reader.md

Drops the SKILL.md into .claude/skills/config-reader.md. Works with Claude Code, Cursor, and any agent that loads SKILL.md files from .claude/skills/.

Config Reader

Read and merge .agents.yml and .agents.local.yml configuration files. Local config overrides base config.

Requires: yq (brew install yq or snap install yq)

Arguments

$ARGUMENTS format: <field> [default]

Examples:

  • auto_preview false - get top-level field, default to "false"
  • plan.auto_create_task false - get nested field, default to "false"
  • tech_stack generic - get top-level field, default to "generic"
  • browser.type chrome - get nested browser type
  • toolbox.build_task.design_system_path - get deeply nested field

Execution

Run the config reader script with parsed arguments:

bash {baseDir}/scripts/config_reader.sh FIELD DEFAULT

Replace FIELD and DEFAULT with the parsed arguments from $ARGUMENTS.

Return Value

Return ONLY the config value (single line):

  • true
  • rails
  • github

Merge Logic

  1. Local checked first - .agents.local.yml wins if key exists
  2. Fall back to base - .agents.yml if not in local
  3. Default - provided default if neither has the key

Common Fields

Field Description Typical Default
auto_preview Auto-open markdown files false
plan.auto_create_task Auto-create tasks from plans false
tech_stack Primary tech stack generic
task_management Task tracking backend none
workflow Git workflow style branches
toolbox.build_task.design_system_path Design system location (none)
