Migrate Recipes

Migrate Scripts Skill

Apply versioned migration notes to an AutoSkillit recipe.

When to Use

• Called by an agent when user confirms migration (via load_recipe suggestion)
• Called by autoskillit migrate CLI command via run_skill
• Can be invoked directly by user

Arguments

The orchestrator provides all context in the prompt:

• script_path: Absolute path to the script file
• script_content: Current raw YAML of the script
• migration_notes: YAML block of all applicable migration notes
• target_version: Version to stamp after successful migration

Critical Constraints

NEVER:

• Modify the original script file directly
• Skip validation via validate_recipe
• Apply changes without checking if the pattern exists in the script
• Declare success if validation fails after all retry attempts

ALWAYS:

• Save migrated scripts to .autoskillit/temp/migrations/{script_name}.yaml for review
• Validate via validate_recipe before declaring success
• Preserve all existing script fields not targeted by migration changes
• Output a human-readable diff summary of changes applied

Workflow

1. Parse the migration notes to understand what changes are needed
2. For each change, check if the script contains the outdated pattern described in detect:
   • tool: Match steps with this tool value
   • skill_pattern: Match steps whose skill_command in with: contains this substring
   • missing_field: The field that should be added if absent
3. If changes are needed, use /autoskillit:write-recipe in edit mode:
   • Load the skill: invoke /autoskillit:write-recipe via the Skill tool
   • Provide the current YAML content
   • Describe all needed changes with the instruction text and before/after examples
4. Validate the result with validate_recipe
5. On validation failure, retry up to 3 times with error feedback
6. Ensure autoskillit_version is set to the target_version
7. Save the migrated script to .autoskillit/temp/migrations/{script_name}.yaml
8. Output a summary of changes applied

Error Handling

• If all 3 retry attempts fail validation, output the best attempt with a clear warning
• If no patterns are detected (script already up to date), stamp the version and report no changes needed
• If write-recipe produces unexpected output, report the error and preserve the original script

Failure Persistence

If all 3 retry attempts are exhausted without a valid result, BEFORE declaring failure you MUST persist the failure record:

run_python: callable: autoskillit.migration.store.record_from_skill args: name: {recipe stem, e.g. "my-pipeline"} file_path: {absolute path received as script_path argument} file_type: recipe error: {description of last validation error} retries_attempted: 3

After recording, output a clear failure summary and stop.
