Struct MigrationShim 

pub struct MigrationShim { /* private fields */ }

Migration shim for converting legacy agent formats to extensions

This struct provides utilities for:

• Loading legacy agent TOML files with deprecation warnings
• Mapping task agent_type fields to extension manifests
• Converting between legacy and new formats

Implementations

impl MigrationShim

pub fn new() -> Self

Create a new migration shim with default configuration

pub fn with_config(config: DeprecationConfig) -> Self

Create a migration shim with custom deprecation config

pub fn load_legacy_agent( &mut self, path: &Path, ) -> Result<ExtensionManifest, ExtensionError>

Load a legacy agent TOML file, emitting deprecation warning if configured

pub fn load_legacy_agent_str( &mut self, content: &str, path: &PathBuf, ) -> Result<ExtensionManifest, ExtensionError>

Load a legacy agent from string content

pub fn resolve_agent_type( &mut self, agent_type: &str, project_root: &Path, ) -> Option<ExtensionManifest>

Resolve an agent_type to an extension manifest

Searches in order:

1. Cached manifests from previous loads
2. Project-local .scud/agents/<agent_type>.toml
3. Built-in agent definitions (embedded)

Returns the manifest if found, with deprecation warning for legacy formats.

pub fn legacy_paths(&self) -> &[PathBuf]

Get list of paths that were loaded as legacy format

pub fn has_legacy_loads(&self) -> bool

Check if any legacy formats were loaded

pub fn cached_agent_types(&self) -> Vec<&str>

Get cached agent types

pub fn clear_cache(&mut self)

Clear the cache
