type Registry 

type Registry struct {

}

func NewRegistry 

func NewRegistry() *Registry

NewRegistry creates a registry with RegistryScopeAny (no isolation). Prefer NewRegistryWithScope for user/pulse/reflection surfaces.

func NewRegistryWithScope added in v0.25.0 

func NewRegistryWithScope(scope RegistryScope) *Registry

NewRegistryWithScope creates a registry bound to the given scope. Any Register() call whose tool name starts with a forbidden prefix for that scope will panic — this is a compile-time-style guarantee enforced at wiring time to prevent cross-surface tool leakage.

func (*Registry) Scope added in v0.25.0 

func (r *Registry) Scope() RegistryScope

Scope returns the scope this registry was created with.

type RegistryScope added in v0.25.0 

type RegistryScope int

RegistryScope identifies the surface a tool Registry belongs to.

The TARS runtime is split into two surfaces:

  • User surface — chat sessions, agents. Registries use RegistryScopeUser.
  • System surface — pulse (watchdog) and reflection (nightly batch). Pulse uses RegistryScopePulse, reflection uses RegistryScopeReflection.

Each non-Any scope declares prefixes that must NOT be registered in it. This prevents accidental cross-surface tool leakage (e.g. a pulse-only tool ending up in a user chat registry). Violations panic at Register() time — these are programmer errors, not runtime conditions. 

const (
	// RegistryScopeAny is the default scope with no restrictions. It exists
	// for backwards compatibility with NewRegistry() callers and tests that
	// don't care about surface isolation.
	RegistryScopeAny RegistryScope = iota
	// RegistryScopeUser is the user-facing surface (chat, agent).
	RegistryScopeUser
	// RegistryScopePulse is the pulse runtime surface.
	RegistryScopePulse
	// RegistryScopeReflection is the reflection runtime surface.
	RegistryScopeReflection
)

func (RegistryScope) String added in v0.25.0 

func (s RegistryScope) String() string

String returns a human-readable scope name used in panic messages.

func JSONTextResult added in v0.15.0
