| description | Detects, validates, and migrates codex configuration formats (JSON → YAML). Provides deprecation warnings and migration guidance. |
| tools | Bash |
| version | 1.0.0 |
Your responsibility is to detect configuration format, provide deprecation warnings, and assist with migration from legacy JSON format to the preferred YAML format used by @fractary/cli and @fractary/codex SDK.
Configuration Evolution:
- v3.0 (deprecated): JSON at
.fractary/plugins/codex/config.jsonor~/.config/fractary/codex/config.json - v4.0 (current): YAML at
.fractary/codex.yaml(project-level only)
Key Changes:
- Global config deprecated (project-level only)
- JSON format deprecated (YAML preferred)
- Version bumped to 4.0 for CLI compatibility
Operation: detect
Purpose: Detect configuration format and provide migration guidance.
Steps:
Execute Detection Script:
./scripts/detect-config.shParse Response:
status: "found" or "not_found"format: "json" or "yaml"location: "project" or "global"path: Absolute path to configis_preferred: Boolean - true if YAML project configmigration_needed: Boolean - true if JSON or globaldeprecation_warning: String - warning message if deprecated
Output Results:
IF status == "not_found":
📋 Configuration Status: Not Found
No codex configuration detected.
Next Steps:
1. Run: /fractary-codex:init
2. This will create: .fractary/codex.yaml
Preferred format: YAML at .fractary/codex.yaml
IF format == "yaml" AND location == "project":
✅ Configuration Status: OK
Format: YAML (preferred)
Location: .fractary/codex.yaml
Status: Up to date
No migration needed.
IF format == "json" AND location == "project":
⚠️ Configuration Status: Deprecated
Format: JSON (deprecated)
Location: .fractary/plugins/codex/config.json
Status: Migration recommended
Deprecation Warning:
JSON format is deprecated. Please migrate to YAML format.
To migrate:
1. Preview: USE SKILL: config-helper with operation="migrate" and dry_run=true
2. Execute: USE SKILL: config-helper with operation="migrate"
3. This creates: .fractary/codex.yaml (version 4.0)
IF format == "json" AND location == "global":
⚠️ Configuration Status: Legacy
Format: JSON (deprecated)
Location: ~/.config/fractary/codex/config.json
Status: Migration required
Deprecation Warning:
Global config is deprecated. Please migrate to project-level YAML config.
To migrate:
1. cd to your project directory
2. Preview: USE SKILL: config-helper with operation="migrate" and dry_run=true
3. Execute: USE SKILL: config-helper with operation="migrate" and remove_source=true
4. This creates: .fractary/codex.yaml (version 4.0)
Operation: migrate
Purpose: Migrate configuration from JSON to YAML format.
Steps:
Validate Prerequisites:
- Check jq installed:
command -v jq - Check yq installed:
command -v yq - If missing: provide installation instructions and STOP
- Check jq installed:
Execute Migration Script:
./scripts/migrate-config.sh \ --source "${source_path}" \ --target "${target_path}" \ ${dry_run ? "--dry-run" : ""} \ ${remove_source ? "--remove-source" : ""}Parse Response:
IF dry_run == true:
{
"status": "success",
"operation": "dry-run",
"source": {"path": "...", "format": "json"},
"target": {"path": "...", "format": "yaml"},
"would_remove_source": false,
"preview": "...yaml content..."
}
IF dry_run == false:
{
"status": "success",
"operation": "migrate",
"source": {"path": "...", "format": "json", "removed": false},
"target": {"path": "...", "format": "yaml", "created": true},
"message": "Configuration migrated successfully",
"next_steps": [...]
}
- Output Results:
IF dry_run == true:
🔍 Migration Preview (Dry Run)
Source: .fractary/plugins/codex/config.json (JSON)
Target: .fractary/codex.yaml (YAML)
Changes:
- Format: JSON → YAML
- Version: 3.0 → 4.0 (CLI compatible)
- Location: .fractary/plugins/codex/ → .fractary/

To execute migration:
USE SKILL: config-helper with operation="migrate" and dry_run=false
IF dry_run == false:
✅ Configuration Migrated Successfully
Source: .fractary/plugins/codex/config.json
Target: .fractary/codex.yaml
Actions taken:
✓ Converted JSON → YAML
✓ Updated version: 3.0 → 4.0
✓ Created: .fractary/codex.yaml
{remove_source ? "✓ Removed source JSON config" : "○ Source JSON config preserved"}
Next Steps:
1. Review new config: cat .fractary/codex.yaml
2. Test CLI: fractary codex health
3. Update any scripts referencing old path
{!remove_source ? "4. Remove old config: rm .fractary/plugins/codex/config.json" : ""}

When source JSON is malformed:
- Show JSON validation error
- Suggest fixing source manually
- Or recreating config with /fractary-codex:init
- Don't attempt migration
Validation Failures

Migration Benefits
JSON → YAML:
- More readable and maintainable
- Standard format for @fractary/cli
- Better comments support
- Easier to edit manually
Global → Project:
- Version controlled with project
- No global state pollution
- Easier team collaboration
- Clear per-project configuration
Version Compatibility
- v3.0: JSON format (plugins/codex/config.json)
- v4.0: YAML format (.fractary/codex.yaml)
Both formats supported by SDK, but CLI prefers YAML.
