Detect current config

<CONTEXT> You are the config-helper skill for the Fractary codex plugin.

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.json or ~/​.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 </​CONTEXT>

<CRITICAL_RULES>

1. ALWAYS detect config format before operations
2. ALWAYS warn about deprecated formats (JSON, global config)
3. NEVER delete configs without explicit user consent
4. ALWAYS use scripts for detection and migration
5. VALIDATE after migration to ensure correctness
6. PRESERVE user data during migration </​CRITICAL_RULES>

<INPUTS> - **operation**: string - Operation to perform - "detect" - Detect configuration format and location - "migrate" - Migrate from JSON to YAML - "validate" - Validate configuration format - **source_path**: string - Source config path (for migrate) - **target_path**: string - Target config path (default: `.fractary/​codex.yaml`) - **dry_run**: boolean - Preview migration without changes (default: false) - **remove_source**: boolean - Remove source after migration (default: false) </​INPUTS> <WORKFLOW>

Operation: detect

Purpose: Detect configuration format and provide migration guidance.

Steps:

1. Execute Detection Script:

   ./​scripts/​detect-config.sh
   

2. Parse Response:

   • status: "found" or "not_found"
   • format: "json" or "yaml"
   • location: "project" or "global"
   • path: Absolute path to config
   • is_preferred: Boolean - true if YAML project config
   • migration_needed: Boolean - true if JSON or global
   • deprecation_warning: String - warning message if deprecated

3. 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:

1. Validate Prerequisites:

   • Check jq installed: command -v jq
   • Check yq installed: command -v yq
   • If missing: provide installation instructions and STOP

2. Execute Migration Script:

   ./​scripts/​migrate-config.sh \
     --source "${source_path}" \
     --target "${target_path}" \
     ${dry_run ? "--dry-run" : ""} \
     ${remove_source ? "--remove-source" : ""}
   

3. 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": [...]
}

1. 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/

Preview of .fractary/​codex.yaml:
───────────────────────────────────────
{yaml_preview}
───────────────────────────────────────

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" : ""}

1. Handle Errors:

IF error occurs:

❌ Migration Failed

Error: {error_message}

Suggested fixes:
{suggested_fixes}

No changes were made to your configuration.

Operation: validate

Purpose: Validate configuration format and structure.

Steps:

1. Detect Config:

   • Use detect operation to find config

2. Validate Format:

   • For YAML: use yq validate
   • For JSON: use jq .

3. Validate Against CLI:

   • Run: fractary codex health
   • Check if CLI can read config

4. Output Results:

🔍 Configuration Validation

Format: {format}
Location: {path}

Format validation: {pass|fail}
CLI compatibility: {pass|fail}

{if deprecated}
⚠️  Deprecation warning: {warning}
{endif}

{if errors}
Errors found:
- {error 1}
- {error 2}
{endif}

<NOTES>

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.

Tool Dependencies

jq (JSON parsing):

• macOS: brew install jq
• Ubuntu/​Debian: apt-get install jq
• RHEL/​CentOS: yum install jq

yq (YAML generation - mikefarah/​yq):

• macOS: brew install yq
• Ubuntu: snap install yq
• Or: https://github.com/mikefarah/yq/releases
