Config Orchestration

Manage project configuration for SDD projects. Each operation delegates to the system CLI.

Input

Invoked by sdd-run.md with:

• operation — The config operation to perform
• args — Remaining arguments after the operation

Operations

Operation	Description
generate	Generate merged config file for a target environment
validate	Validate config against schemas
diff	Show differences between environments
add-env	Add a new environment directory

No Arguments

When invoked without an operation, display usage:

⚠ Missing required operation argument.

USAGE:
  /sdd-run config <operation> [options]

OPERATIONS:
  generate    Generate merged config file for a target environment
  validate    Validate config against schemas
  diff        Show differences between environments
  add-env     Add a new environment directory

EXAMPLES:
  /sdd-run config generate --env production
  /sdd-run config validate
  /sdd-run config diff local production
  /sdd-run config add-env staging

---

generate

Generate a merged config file for a target environment.

/sdd-run config generate --env <env> [--component <name>] [--output <path>]

Arguments:

• --env <env> (required): Target environment (e.g., local, staging, production)
• --component <name> (optional): Extract only this component's config section
• --output <path> (optional): Write to file instead of stdout

Behavior:

1. Merges envs/default/config.yaml with envs/{env}/config.yaml
2. Validates against schemas/config.schema.json before outputting (fails if invalid)
3. Places schema alongside output (e.g., config.yaml + config.schema.json) for runtime validation
4. If --component specified, extracts just that section (outputs section contents only, no wrapper key)

Implementation:

<plugin-root>/fullstack-typescript/system/system-run.sh config generate --env <env> [--component <name>] [--output <path>]

---

validate

Validate config files against schemas.

/sdd-run config validate [--env <env>]

Arguments:

• --env <env> (optional): Validate only this environment. If omitted, validates all environments.

Behavior:

1. Reads config YAML files from envs/{env}/
2. Validates against JSON Schema in schemas/config.schema.json
3. Reports all schema violations with line numbers

Implementation:

<plugin-root>/fullstack-typescript/system/system-run.sh config validate [--env <env>]

---

diff

Show differences between two environments.

/sdd-run config diff <env1> <env2>

Arguments:

• <env1> (required): First environment to compare
• <env2> (required): Second environment to compare

Behavior:

1. Generates merged config for both environments
2. Shows additions, removals, and changes between them
3. Outputs in a readable format

Implementation:

<plugin-root>/fullstack-typescript/system/system-run.sh config diff <env1> <env2>

---

add-env

Add a new environment directory.

/sdd-run config add-env <env-name>

Arguments:

• <env-name> (required): Name of the new environment

Behavior:

1. Creates envs/{env-name}/ directory
2. Creates config.yaml with schema reference and empty structure
3. Config inherits from envs/default/

Implementation:

<plugin-root>/fullstack-typescript/system/system-run.sh config add-env <env-name>

---

Merge Algorithm

When merging envs/default/ → envs/{env}/:

• Objects: Recursively merged (both levels' keys preserved)
• Arrays: Replaced entirely (env array replaces default array)
• Primitives: Env value replaces default value
• Null values: Explicitly setting null removes the key

Output

Returns the system CLI output for the requested operation.
