type ControllerLookup ¶

type ControllerLookup func() PlanModeController

ControllerLookup is the late-bound factory closure passed to the EnterPlanMode / ExitPlanMode constructors. Returning nil disables the tool — Execute surfaces a clear "no controller installed" error instead of crashing.

type EnterPlanModeTool ¶

type EnterPlanModeTool struct {
	// contains filtered or unexported fields
}

EnterPlanModeTool flips the session into plan mode, stashes the prior mode for restore, and prepares an empty plan file the model writes to.

func NewEnterPlanMode(lookup ControllerLookup) *EnterPlanModeTool

func (t *EnterPlanModeTool) Description() string

func (t *EnterPlanModeTool) Execute(_ context.Context, logger *slog.Logger, _ json.RawMessage) (tools.Result, error)

func (t *EnterPlanModeTool) Name() string

func (t *EnterPlanModeTool) Schema() json.RawMessage

type EnterWorktreeTool ¶

type EnterWorktreeTool struct {
	// contains filtered or unexported fields
}

EnterWorktreeTool creates `.evva/worktrees/<slug>/` on a new branch `worktree-<slug>` and switches the agent's workdir into it.

func NewEnterWorktree(lookup WorktreeControllerLookup) *EnterWorktreeTool

func (t *EnterWorktreeTool) Description() string

func (t *EnterWorktreeTool) Execute(ctx context.Context, logger *slog.Logger, input json.RawMessage) (tools.Result, error)

func (t *EnterWorktreeTool) Name() string

func (t *EnterWorktreeTool) Schema() json.RawMessage

type ExitPlanModeTool ¶

type ExitPlanModeTool struct {
	// contains filtered or unexported fields
}

ExitPlanModeTool reads the plan file, asks the user to approve, and restores the pre-plan permission mode on approval. Rejection leaves the session in ModePlan with the user's reason surfaced to the model.

func NewExitPlanMode(lookup ControllerLookup) *ExitPlanModeTool

func (t *ExitPlanModeTool) Description() string

func (t *ExitPlanModeTool) Execute(ctx context.Context, logger *slog.Logger, input json.RawMessage) (tools.Result, error)

func (t *ExitPlanModeTool) Name() string

func (t *ExitPlanModeTool) Schema() json.RawMessage

type ExitWorktreeTool ¶

type ExitWorktreeTool struct {
	// contains filtered or unexported fields
}

ExitWorktreeTool tears down (or keeps) a worktree session opened by EnterWorktree, restoring the agent's original workdir.

func NewExitWorktree(lookup WorktreeControllerLookup) *ExitWorktreeTool

func (t *ExitWorktreeTool) Description() string

func (t *ExitWorktreeTool) Execute(ctx context.Context, logger *slog.Logger, input json.RawMessage) (tools.Result, error)

func (t *ExitWorktreeTool) Name() string

func (t *ExitWorktreeTool) Schema() json.RawMessage

type PlanModeController ¶

type PlanModeController interface {
	PermissionMode() permission.Mode
	SetPermissionMode(m permission.Mode)
	PrePlanMode() permission.Mode
	SetPrePlanMode(m permission.Mode)
	Workdir() string
	Broker() permission.Broker
	AgentID() string
}

PlanModeController is the seam between the EnterPlanMode / ExitPlanMode tools and the owning agent. The agent satisfies it directly; the tool constructors take a lookup closure (returns a PlanModeController) so builtin registration can stay late-bound — the agent installs itself after toolset.NewToolState runs.

The interface is intentionally narrow: only what the two plan-mode tools actually touch. Permission mode mutation, the pre-plan stash (used by ExitPlanMode to restore), the workdir (for the plan-file path), the approval broker (for ExitPlanMode's user-approval gate), and the AgentID that the broker uses to route the approval event.

type WorktreeController ¶

type WorktreeController interface {
	Workdir() string
	SwitchWorkdir(path string) error
	WorktreeSession() *WorktreeSession
	BeginWorktreeSession(s WorktreeSession)
	EndWorktreeSession()
	AgentID() string
	Logger() *slog.Logger
}

WorktreeController is the seam between the EnterWorktree / ExitWorktree tools and the owning agent — same shape and lifecycle as PlanModeController: the agent satisfies it directly, the tool constructors take a lookup closure so the agent can install itself after toolset construction without an init ordering hazard.

SwitchWorkdir is the load-bearing call: implementations rebuild any active tool that captured the OLD workdir at construction time (filesystem tools, the bash tool), reload the EVVA.md / USER_PROFILE.md memory snapshot from the new path, and re-render the system prompt so the next LLM turn sees the new working directory.

BeginWorktreeSession / EndWorktreeSession bracket a logical session; while a session is live, WorktreeSession() returns a non-nil pointer so EnterWorktree can refuse re-entry and ExitWorktree knows whether to no-op or actually tear the worktree down.

type WorktreeControllerLookup ¶

type WorktreeControllerLookup func() WorktreeController

WorktreeControllerLookup is the late-bound factory closure passed to the EnterWorktree / ExitWorktree constructors. Returning nil disables the tool — Execute surfaces a clear "no controller installed" error instead of crashing.

type WorktreeSession ¶

type WorktreeSession struct {
	// OriginalWorkdir is the workdir the agent was in before EnterWorktree
	// fired. ExitWorktree restores it.
	OriginalWorkdir string
	// Path is the absolute path to the worktree directory.
	Path string
	// Branch is the branch name created with `git worktree add -b`.
	Branch string
	// Slug is the flattened slug used to compose Path and Branch — kept
	// for logging and the tool's confirmation message.
	Slug string
	// CreatedBySubagent marks worktrees the AgentTool's isolation path
	// created (vs the user-invoked EnterWorktree tool). The post-run
	// cleanup in spawn.go uses this to decide whether to auto-remove on
	// clean exit.
	CreatedBySubagent bool
	CreatedAt         time.Time
}

WorktreeSession records the metadata the worktree tools and AgentTool isolation need to clean up a worktree on exit. It is also what the subagent spawner threads into a child constructed under `isolation: "worktree"` — the child carries it so its own ExitWorktree (rarely invoked from a subagent but possible) and the post-run cleanup path in spawn.go agree on what to tear down.

func CreateForSubagent(ctx context.Context, parentWorkdir, agentName string) (WorktreeSession, error)
