# Autocomplete -- Technical Specification

**Version**: v1.0.0 | **Status**: Active | **Last Updated**: March 2026

## Overview

Placeholder submodule for shell tab-completion functionality. Intended to provide autocomplete providers for command names, arguments, file paths, and module names within the Codomyrmex interactive shell.

## Architecture

This submodule is currently a namespace placeholder. The `__init__.py` exports an empty `__all__` list. Completion logic is expected to integrate with the readline or prompt-toolkit layer used by the interactive shell.

## Current State

- `__init__.py`: Module docstring ("Shell completions") and empty `__all__` -- no completion classes implemented yet.
- Future scope: pluggable completion providers with context-aware suggestions.

## Planned Interface

When implemented, the module would expose:

| Class / Function | Purpose |
|-----------------|---------|
| `CompletionProvider` | Base class for autocomplete sources |
| `CommandCompleter` | Completes registered command names |
| `PathCompleter` | Completes filesystem paths |
| `ModuleCompleter` | Completes Codomyrmex module names |

## Dependencies

- **Internal**: `terminal_interface.commands` (command names for completion), `terminal_interface.shells` (shell integration)
- **External**: `readline` or `prompt_toolkit` (optional, for shell integration)

## Constraints

- Not yet implemented; importing yields an empty namespace.
- Zero-mock: `NotImplementedError` for unimplemented paths.

## Navigation

- [README.md](README.md) | [AGENTS.md](AGENTS.md)
- Parent: [terminal_interface](../README.md)
