From 5662caad2749935fa8ca170535df8adf1e7fe7a4 Mon Sep 17 00:00:00 2001 From: Matthew Upson Date: Thu, 22 Jan 2026 13:05:54 +0100 Subject: [PATCH 1/4] feat: Release v1.2.0 - Security Groups, File Transfer, and Major Improvements ## New Features ### Security Group Management - IP whitelisting commands (`instance add-ip` / `instance remove-ip`) - CIDR notation support for flexible IP range management ### Volume Management - `volume resize` command for EBS volume management ### File Transfer - Built-in `instance copy` and `instance sync` commands via rsync/scp ### Cost Tracking - Cumulative instance cost tracking over time - Dynamic region location lookup via AWS SSM for accurate pricing ### Instance Management - `instance exec` command to run commands on remote instances - `--start` / `--no-start` flags for connect command to auto-start stopped instances - Configurable timeout for SSH connect command (`--timeout` flag) - Cache clearing mechanism for AWS clients (`--clear-cache` flag) ### Consistency Improvements - Added `--yes` flag to ami create, snapshot create, instance type, and instance launch commands - Exclude terminated instances by default in instance list command ## Refactoring - Standardized error handling with `@handle_cli_errors` decorator - Consolidated SSH configuration into reusable SSHConfig class - Extracted shared utilities: create_table(), resolve_instance_or_exit(), get_status_style() - Standardized table column styling across CLI - Moved timing constants to settings.py - Refactored ECS module with cleaner command names ## Bug Fixes - AMI pagination for large AMI counts (>1000 images) - SSH key path validation before connect/exec commands - Instance type format validation - Empty DNS validation in connect command - Exit code semantics for non-success scenarios - Mutual exclusivity validation for conflicting flags - ECS scale command validation for desired_count parameter - Debug logging for silent failure cases in pricing module ## New Modules - `remote/sg.py` - Security group management - `remote/tracking.py` - Cost tracking functionality - `remote/instance_resolver.py` - Instance resolution utilities ## Test Coverage - 400+ tests with comprehensive edge case coverage - New test suites for sg, tracking, and volume_resize modules --- CHANGELOG.md | 39 + CLAUDE.md | 59 + progress.md | 41 + pyproject.toml | 4 +- remote/__main__.py | 4 + remote/ami.py | 207 +- remote/config.py | 271 +-- remote/ecs.py | 286 ++- remote/exceptions.py | 2 -

`tests/test_utils.py` - -**Issue:** The `get_instance_ids()` function had inconsistent filtering behavior compared to `get_instance_info()`: - -1. `get_instance_info()` iterates through ALL instances in each reservation but filters out instances without a Name tag -2. `get_instance_ids()` only took the FIRST instance from each reservation and did NOT filter by Name tag - -This inconsistency meant the arrays returned by these functions could have different lengths when used together. The code worked around this with `strict=False` in `zip()` calls, which silently truncated to the shortest array - masking potential data misalignment bugs. - -**Changes:** -- Updated `get_instance_ids()` in `remote/utils.py` to: - - Iterate through ALL instances in each reservation (not just the first) - - Filter instances to only include those with a Name tag (matching `get_instance_info()`) -- Changed `strict=False` to `strict=True` in zip calls in: - - `remote/instance.py:134` (list_instances command) - - `remote/config.py:434` (add command) -- Added new test `test_get_instance_ids_filters_instances_without_name_tag()` to verify the filtering behavior - ---- - -## 2026-01-18: Remove unused `validate_snapshot_id()` function - -**Files:** `remote/validation.py`, `tests/test_validation.py` - -**Issue:** The `validate_snapshot_id()` function was defined in `validation.py` but never used anywhere in the application. While it was tested in `test_validation.py`, the function itself had no callers in the actual codebase. This is dead code that should be removed to keep the codebase clean. - -**Changes:** -- Removed the `validate_snapshot_id()` function from `remote/validation.py` (lines 104-129) -- Removed the `TestValidateSnapshotId` test class from `tests/test_validation.py` (lines 190-219) -- Removed the `validate_snapshot_id` import from `tests/test_validation.py` - ---- - -## 2026-01-18: Standardize Typer parameter style in `status()` command - -**File:** `remote/instance.py` - -**Issue:** The `status()` command used the `Annotated[]` style for parameter type annotations while all other commands in the file (and throughout the codebase) used the simpler inline style: - -- `status()` used: - ```python - instance_name: Annotated[str | None, typer.Argument(help="Instance name")] = None - watch: Annotated[bool, typer.Option("--watch", "-w", help="...")] = False - ``` - -- All other commands used: - ```python - instance_name: str | None = typer.Argument(None, help="Instance name") - watch: bool = typer.Option(False, "--watch", "-w", help="...") - ``` - -This inconsistency: -1. Made the codebase harder to read -2. Created confusion about which style to use for new commands -3. Required an unnecessary `Annotated` import in `instance.py` - -**Changes:** -- Changed `status()` parameters from `Annotated[]` style to inline style: - - `instance_name`: `Annotated[str | None, typer.Argument(help="Instance name")] = None` → `str | None = typer.Argument(None, help="Instance name")` - - `watch`: `Annotated[bool, typer.Option("--watch", "-w", help="...")] = False` → `bool = typer.Option(False, "--watch", "-w", help="...")` - - `interval`: `Annotated[int, typer.Option("--interval", "-i", help="...")] = 2` → `int = typer.Option(2, "--interval", "-i", help="...")` -- Removed the now-unused `Annotated` import from `typing` - ---- - -## 2026-01-18: Fix inconsistent docstring formatting in `ecs.py` - -**File:** `remote/ecs.py` - -**Issue:** Multiple functions had inconsistent docstring formatting compared to the rest of the codebase: -1. Docstrings with opening `"""` on a separate line instead of inline with the description -2. Missing 4-space indentation in Args and Returns sections -3. Redundant type annotations in docstrings (types should be in function signatures only) - -Affected functions: -- `get_all_clusters()` (lines 46-57) -- `get_all_services()` (lines 77-91) -- `scale_service()` (lines 111-122) -- `prompt_for_cluster_name()` (lines 137-143) -- `prompt_for_services_name()` (lines 180-189) -- `list_clusters()` (lines 249-254) -- `list_services()` (lines 273-279) -- `scale()` (lines 302-313) - -**Changes:** -- Moved docstring descriptions to same line as opening `"""` -- Added proper 4-space indentation to Args and Returns sections -- Removed redundant type annotations (e.g., `cluster_name (str):` → `cluster_name:`) -- Removed redundant type prefixes in Returns (e.g., `list: A list of...` → `A list of...`) - -This makes the docstrings consistent with the style used in `utils.py` and other modules. - ---- - -## 2026-01-18: Replace silent exception handler in `list_launch_templates()` - -**File:** `remote/ami.py` - -**Issue:** The `list_launch_templates()` function silently swallowed exceptions with a bare `pass`: -```python -except (ResourceNotFoundError, AWSServiceError): - pass -``` - -This is problematic because: -1. Silently ignoring errors hides potential problems from users -2. Users have no indication when version details fail to load -3. Debugging becomes difficult when errors are silently discarded - -**Changes:** -- Replaced silent `pass` with a warning message: `"Warning: Could not fetch version details"` -- The warning uses the same `[yellow]` styling pattern used elsewhere in the codebase (e.g., `utils.py:354`, `config.py:264`) - -This maintains the non-fatal behavior (template listing continues) while informing users that some details couldn't be retrieved. - ---- - -## 2026-01-18: Replace overly broad exception handling in `list_launch_templates()` - -**File:** `remote/ami.py` - -**Issue:** The `list_launch_templates()` function had overly broad exception handling at line 141: -```python -except (ResourceNotFoundError, Exception): - pass -``` - -This is problematic because: -1. `Exception` is too broad and catches all exceptions, hiding unexpected errors -2. `ResourceNotFoundError` is a subclass of `Exception`, making it redundant in the tuple -3. Silently passing on all exceptions can mask bugs - -The function `get_launch_template_versions()` (called within the try block) documents that it raises only: -- `ResourceNotFoundError`: If template not found -- `AWSServiceError`: If AWS API call fails - -**Changes:** -- Added `AWSServiceError` to imports from `remote.exceptions` -- Changed exception handling from `(ResourceNotFoundError, Exception)` to `(ResourceNotFoundError, AWSServiceError)` - -This makes the error handling explicit and specific to the documented exceptions. - ---- - -## 2026-01-18: Fix incorrect config key `ssh_key` → `ssh_key_path` - -**File:** `remote/instance.py` - -**Issue:** The `connect()` function was using the wrong config key name when retrieving the SSH key path from configuration: -- Line 415 used `config_manager.get_value("ssh_key")` (incorrect) -- The valid config key defined in `remote/config.py` is `"ssh_key_path"` - -This caused the SSH key configuration to fail silently - users who set `ssh_key_path` in their config would not have the key applied when connecting via SSH. - -**Changes:** -- Fixed line 415: Changed `"ssh_key"` to `"ssh_key_path"` in `get_value()` call -- Fixed line 329: Updated help text to reference `ssh_key_path` instead of `ssh_key` - ---- - -## 2026-01-18: Remove unused `cfg` parameter from `get_instance_name()` - -**File:** `remote/utils.py` - -**Issue:** The `get_instance_name()` function had an unused parameter `cfg: ConfigParser | None = None`. The docstring mentioned it was for "backward compatibility" but: -1. The parameter was never used inside the function -2. All callers (8 call sites across instance.py, ami.py, snapshot.py, volume.py) called the function without arguments - -**Changes:** -- Removed the unused `cfg` parameter from the function signature -- Removed the corresponding parameter documentation from the docstring -- Removed the now-unused `from configparser import ConfigParser` import - ---- - -## 2026-01-18: Remove unnecessary `builtins` import from `instance.py` - -**File:** `remote/instance.py` - -**Issue:** The file imported `builtins` and used `builtins.list[dict[str, str]]` for a type annotation on line 742. This is unnecessary because: -1. In Python 3.9+, `list` can be used directly in type annotations without importing from `builtins` -2. The `builtins` module was only used for this single type annotation -3. Using `list` directly is more idiomatic and readable - -**Changes:** -- Removed the `import builtins` statement from line 1 -- Changed `builtins.list[dict[str, str]]` to `list[dict[str, str]]` in the `tags` variable annotation - ---- - -## 2026-01-18: Remove unused Typer app instance from `utils.py` - -**File:** `remote/utils.py` - -**Issue:** Line 33 defined `app = typer.Typer()` but this app instance was never used anywhere in the codebase: -1. No commands were registered to this app -2. No other modules imported this app -3. The `utils.py` module is a utility module, not a CLI entrypoint - -The `typer` import itself is still needed for other uses in the file (typer.Exit, typer.secho, typer.colors). - -**Changes:** -- Removed the unused `app = typer.Typer()` line - ---- - -## 2026-01-18: Use cached STS client in `get_account_id()` - -**File:** `remote/utils.py` - -**Issue:** The `get_sts_client()` function (lines 46-55) was defined as a cached client factory but was never used. The `get_account_id()` function at line 86 created a new STS client directly with `boto3.client("sts")` instead of using the cached `get_sts_client()` function. - -This was inconsistent with the pattern used for EC2 clients, where `get_ec2_client()` is consistently used throughout the codebase. - -**Changes:** -- Changed line 86 from `boto3.client("sts").get_caller_identity()` to `get_sts_client().get_caller_identity()` -- This makes the code consistent with the EC2 client pattern and utilizes the caching provided by `@lru_cache` - ---- - -## 2026-01-18: Remove unnecessary `enumerate()` in `get_instance_ids()` - -**File:** `remote/utils.py` - -**Issue:** The `get_instance_ids()` function at line 390 used `enumerate()` to iterate over instances: -```python -for _i, reservation in enumerate(instances): -``` - -The loop index `_i` was never used in the function body. The underscore prefix conventionally indicates an unused variable, but in this case the `enumerate()` call itself was unnecessary. - -**Changes:** -- Changed from `for _i, reservation in enumerate(instances):` to `for reservation in instances:` -- Removes dead code and improves clarity by eliminating unused variable - ---- - -## 2026-01-18: Remove unused `drop_nameless` parameter from `get_instance_info()` - -**File:** `remote/utils.py` - -**Issue:** The `get_instance_info()` function had an unused parameter `drop_nameless: bool = False`: -1. The parameter was defined in the function signature and documented in the docstring -2. However, the function body always skips instances without a Name tag (lines 336-338), regardless of the parameter value -3. No callers in the codebase ever passed this parameter - -The parameter was misleading because: -- Default value `False` implied nameless instances would be included by default -- But the actual behavior always excluded them (as if `drop_nameless=True`) - -**Changes:** -- Removed the `drop_nameless` parameter from the function signature -- Removed the parameter documentation from the docstring -- Added a "Note" section to the docstring clarifying that instances without a Name tag are automatically excluded - ---- - -## 2026-01-18: Remove deprecated `ec2_client` backwards compatibility shim - -**File:** `remote/utils.py` - -**Issue:** The module contained deprecated backwards compatibility code for accessing `ec2_client` as a module-level attribute: -1. Lines 59-62 had a comment indicating the deprecated attribute "will be removed in v0.5.0" -2. Lines 65-74 defined a `__getattr__` function providing lazy access to `ec2_client` for backwards compatibility -3. The `Any` type was imported solely for this `__getattr__` function's return type - -After scanning the entire codebase, no code was found using the deprecated `ec2_client` attribute: -- All modules use `get_ec2_client()` function directly -- All test files use local mock variables named `mock_ec2_client`, not the deprecated module attribute - -**Changes:** -- Removed the deprecation comment block (lines 59-62) -- Removed the `__getattr__` function (lines 65-74) - ---- - -## 2026-01-18: Remove deprecated `ecs_client` backwards compatibility shim - -**File:** `remote/ecs.py` - -**Issue:** The module contained dead code for backwards compatibility access to `ecs_client` as a module-level attribute: -1. Lines 29-30 had a comment about backwards compatibility -2. Lines 33-37 defined a `__getattr__` function providing lazy access to `ecs_client` -3. The `Any` type was imported solely for this `__getattr__` function's return type - -After scanning the entire codebase, no code was found using the deprecated `ecs_client` attribute: -- All ECS functions use `get_ecs_client()` function directly (lines 72, 106, 136) -- All test files mock `get_ecs_client`, not the deprecated module attribute -- No imports of `ecs_client` exist anywhere in the codebase - -This is similar to the `ec2_client` shim that was removed from `utils.py` in a previous refactor. - -**Changes:** -- Removed the `Any` type from imports (no longer needed) -- Removed the backwards compatibility comment (lines 29-30) -- Removed the `__getattr__` function (lines 33-37) - ---- - -## 2026-01-18: Remove unused `ENV_PREFIX` constant from `config.py` - -**File:** `remote/config.py` - -**Issue:** Line 30 defined `ENV_PREFIX = "REMOTE_"` but this constant was never used anywhere in the codebase: -1. The actual environment prefix is hardcoded in `RemoteConfig.model_config` as `env_prefix="REMOTE_"` (line 52) -2. No other code references `ENV_PREFIX` -3. The constant was misleading since it appeared to be the source of truth but wasn't actually used - -**Changes:** -- Removed the unused `ENV_PREFIX = "REMOTE_"` constant -- Removed the associated comment "Environment variable mapping for config values" - ---- - -## 2026-01-18: Rename `in_duration` parameter to `stop_in` for consistency - -**File:** `remote/instance.py` - -**Issue:** The `stop()` function used parameter name `in_duration` while the `start()` function used `stop_in` for the same purpose (scheduling automatic shutdown). This inconsistency created cognitive overhead when working with both functions: -- `start()` (line 375): parameter `stop_in` with CLI flag `--stop-in` -- `stop()` (line 601): parameter `in_duration` with CLI flag `--in` - -Both parameters serve the same purpose: specifying a duration after which the instance should be stopped. - -**Changes:** -- Renamed `in_duration` to `stop_in` in the `stop()` function signature (line 601) -- Updated all references to `in_duration` within the function body (lines 641, 649) -- The CLI flag `--in` remains unchanged for backwards compatibility - ---- - -## 2026-01-18: Rename `type` function and parameter to avoid shadowing Python built-in - -**File:** `remote/instance.py` - -**Issue:** The `type()` command function and its `type` parameter shadowed the Python built-in `type`. This is problematic because: -1. The function name `type` shadows the built-in `type()` function at module scope -2. The parameter `type` shadows the built-in within the function body -3. This prevents using the built-in `type()` for any introspection within this function -4. It's a code smell that can cause subtle bugs and confuses static analysis tools - -**Changes:** -- Renamed function from `type` to `instance_type` with `@app.command("type")` decorator to preserve CLI command name -- Renamed parameter from `type` to `new_type` to avoid shadowing the built-in -- Updated all references within the function body to use `new_type` -- Changed the else branch's reassignment from `type = get_instance_type(...)` to `current_instance_type = get_instance_type(...)` to avoid confusion - ---- - -## 2026-01-18: Add missing `width=200` to Console initialization in `config.py` - -**File:** `remote/config.py` - -**Issue:** The module-level `console` initialization on line 18 was inconsistent with all other modules: -- `config.py` used: `Console(force_terminal=True)` (missing width) -- All other modules used: `Console(force_terminal=True, width=200)` - -Affected modules with consistent pattern: -- `utils.py:32`: `Console(force_terminal=True, width=200)` -- `snapshot.py:13`: `Console(force_terminal=True, width=200)` -- `ecs.py:30`: `Console(force_terminal=True, width=200)` -- `volume.py:13`: `Console(force_terminal=True, width=200)` -- `instance.py:44`: `Console(force_terminal=True, width=200)` -- `ami.py:24`: `Console(force_terminal=True, width=200)` - -This inconsistency could cause different output formatting in `config.py` commands compared to other modules. - -**Changes:** -- Changed line 18 from `Console(force_terminal=True)` to `Console(force_terminal=True, width=200)` - ---- - -## 2026-01-18: Remove unused `is_instance_stopped()` function - -**File:** `remote/utils.py` - -**Issue:** The `is_instance_stopped()` function (lines 424-460) was defined but never called anywhere in the production codebase: -1. The function checked if an EC2 instance was in "stopped" state -2. It was only referenced in test files (`tests/test_utils.py`) -3. No production code in the `remote/` directory ever called this function -4. The similar function `is_instance_running()` is actively used, but `is_instance_stopped()` was dead code - -**Changes:** -- Removed the `is_instance_stopped()` function from `remote/utils.py` -- Removed the import of `is_instance_stopped` from `tests/test_utils.py` -- Removed the two associated test functions `test_is_instance_stopped_true()` and `test_is_instance_stopped_false()` from `tests/test_utils.py` - ---- - -## 2026-01-18: Remove duplicate `list_launch_templates()` function from `instance.py` - -**File:** `remote/instance.py` - -**Issue:** The `list_launch_templates()` function (lines 922-952) was duplicated in both `instance.py` and `ami.py`: -1. `instance.py` version: Simple implementation with basic table display -2. `ami.py` version: Feature-rich implementation with `--filter` and `--details` options - -The duplicate in `instance.py` was: -- A subset of the `ami.py` functionality -- Inconsistent with DRY (Don't Repeat Yourself) principle -- Creating maintenance burden for similar functionality in two places - -Users can use `remote ami list-templates` which provides the same functionality plus additional features like filtering and detailed output. - -**Changes:** -- Removed the `list_launch_templates()` function from `remote/instance.py` -- Removed the corresponding test `test_list_launch_templates_command()` from `tests/test_instance.py` - ---- - -## 2026-01-18: Remove unused `ConfigurationError` exception class - -**File:** `remote/exceptions.py` - -**Issue:** The `ConfigurationError` exception class (lines 132-142) was defined but never used anywhere in the codebase: -1. No code raised this exception -2. No code caught this exception -3. No tests referenced this exception class -4. The class was complete dead code adding unnecessary lines to the module - -The exception was designed for configuration-related errors but was never integrated into the config handling code. - -**Changes:** -- Removed the `ConfigurationError` class definition from `remote/exceptions.py` - ---- - -## 2026-01-18: Remove unused `InvalidInstanceStateError` exception class - -**File:** `remote/exceptions.py` - -**Issue:** The `InvalidInstanceStateError` exception class (lines 51-65) was defined but never raised anywhere in the codebase: -1. No code raised this exception - grep search for `InvalidInstanceStateError` in the `remote/` directory only found the class definition itself -2. The exception was designed for instance state validation errors but was never integrated -3. Tests existed for the class (`tests/test_exceptions.py` lines 90-118) but only tested that the class worked correctly, not that it was actually used -4. Similar to `ConfigurationError` which was removed in commit 50886f1 - -**Changes:** -- Removed the `InvalidInstanceStateError` class definition from `remote/exceptions.py` -- Removed the import and test class `TestInvalidInstanceStateError` from `tests/test_exceptions.py` - ---- - -## 2026-01-18: Extract `_build_ssh_command()` helper to reduce SSH argument duplication - -**File:** `remote/instance.py` - -**Issue:** The SSH argument building code was duplicated in two functions: -1. `_schedule_shutdown()` (lines 486-494) - built SSH args for scheduling shutdown -2. `_cancel_scheduled_shutdown()` (lines 552-560) - built identical SSH args for cancelling shutdown - -Both functions contained the exact same SSH argument list: -```python -ssh_args = [ - "ssh", - "-o", - "StrictHostKeyChecking=accept-new", - "-o", - "BatchMode=yes", - "-o", - "ConnectTimeout=10", -] -if key: - ssh_args.extend(["-i", key]) -ssh_args.append(f"{user}@{dns}") -``` - -This duplication meant any changes to SSH options (e.g., adding new options, changing timeout) would need to be made in multiple places. - -**Changes:** -- Added new helper function `_build_ssh_command(dns, key, user)` that returns the base SSH command arguments -- Updated `_schedule_shutdown()` to use the new helper -- Updated `_cancel_scheduled_shutdown()` to use the new helper -- Reduced code duplication by ~14 lines - ---- - -## 2026-01-18: Consolidate datetime imports to module level in `instance.py` - -**File:** `remote/instance.py` - -**Issue:** The `datetime` module was imported inconsistently in three different locations inside functions rather than at the module level: -- Line 68: `from datetime import timezone` (inside `_get_raw_launch_times`) -- Line 159: `from datetime import datetime, timezone` (inside `list_instances`) -- Line 498: `from datetime import datetime, timedelta, timezone` (inside `_schedule_shutdown`) - -This pattern is inconsistent with other modules like `utils.py` which imports datetime at the module level (line 2). Inline imports inside functions: -1. Reduce code readability -2. Make it harder to see all module dependencies at a glance -3. Create slight performance overhead from repeated imports (though Python caches them) - -**Changes:** -- Added `from datetime import datetime, timedelta, timezone` at the module level (after line 4) -- Removed the three inline imports from `_get_raw_launch_times`, `list_instances`, and `_schedule_shutdown` functions - ---- - -## 2026-01-18: Centralize console initialization in `utils.py` - -**Issue:** Duplicated `console = Console(force_terminal=True, width=200)` initialization across 7 modules: -- `remote/utils.py:32` -- `remote/ami.py:24` -- `remote/config.py:18` -- `remote/ecs.py:30` -- `remote/instance.py:45` -- `remote/snapshot.py:13` -- `remote/volume.py:13` - -This duplication meant any changes to console configuration would need to be made in 7 places. It also increased the risk of inconsistency (as seen in the previous `config.py` fix where `width=200` was missing). - -**Changes:** -- Kept the single console instance in `remote/utils.py` -- Updated all other modules to import `console` from `remote.utils` instead of creating their own instances -- Removed redundant `from rich.console import Console` imports where Console was only used for the module-level instance - -**Files Modified:** -- `remote/ami.py` - Import console from utils, remove Console import -- `remote/config.py` - Import console from utils, remove Console import -- `remote/ecs.py` - Import console from utils, remove Console import -- `remote/instance.py` - Import console from utils (kept Console import for local use in `_watch_status`) -- `remote/snapshot.py` - Import console from utils, remove Console import -- `remote/volume.py` - Import console from utils, remove Console import - -**Note:** `remote/instance.py` still imports `Console` from `rich.console` because the `_watch_status` function creates a separate Console instance for its Live display functionality. - ---- - -## 2026-01-18: Remove redundant Console creation in `_watch_status()` - -**File:** `remote/instance.py` - -**Issue:** The `_watch_status()` function created a new `Console()` instance on line 305: -```python -watch_console = Console() -``` - -This was redundant because: -1. The module already imports `console` from `remote.utils` (centralized console instance) -2. The local `watch_console` duplicated functionality already available -3. This was noted as an exception in the previous refactor, but there's no reason not to reuse the shared console - -**Changes:** -- Removed the `watch_console = Console()` line from `_watch_status()` -- Changed `Live(console=watch_console, ...)` to `Live(console=console, ...)` -- Changed `watch_console.print(...)` to `console.print(...)` -- Removed the now-unused `from rich.console import Console` import - -This completes the console centralization refactor - all modules now use the shared `console` instance from `remote/utils.py`. - ---- - -## 2026-01-18: Remove redundant `get_instance_type()` call in `instance_type()` function - -**File:** `remote/instance.py` - -**Issue:** The `instance_type()` function called `get_instance_type()` twice to retrieve the same value: -1.
