feat(config): add cross-platform VS Code detection for macOS and Windows #14
Conversation
Add comprehensive specification for fixing VS Code detection on macOS and Windows platforms. Includes: - Multi-platform path detection (Linux, macOS, Windows) - Platform-specific command installation directories - Detailed technical considerations with researched best practices - Cross-platform testing strategy using parametrized tests with mocked sys.platform for comprehensive coverage on any host OS - Clear scope boundaries and success metrics This spec enables the slash command manager to work correctly on all three major platforms without requiring filesystem mocking or multiple test runners.
…ntegrate AGENTS.md standards Reorganize specification and task list to enforce strict Test-Driven Development workflow with explicit phases: - Unit 1: Test Coverage (TDD Phase 1 - write failing tests) - Unit 2-3: Implementation (TDD Phase 2 - write code to pass tests) - Unit 4: Integration Verification (validate no regressions) Integrate critical standards from AGENTS.md: - Update all proof artifacts to use correct 'uv run' command prefix - Document required test execution: 'uv run pytest tests/ -v -m "not integration"' - Clarify integration test requirement: must use 'uv run scripts/run_integration_tests.py' - Add dependency management and Python execution standards Skip integration tests for this feature - unit tests with mocked sys.platform provide sufficient coverage for configuration and method logic changes. 🤖 Generated with Claude Code Co-Authored-By: Claude <[email protected]>

tests/test_config.py (1)
31-46: Detection-dir validation update is sound; optionally assert the new field’s type as well.Allowing detection dirs that start with
"."or contain"Library"/"AppData"matches the new VS Code config while keeping other agents constrained to hidden roots, which is reasonable.To more fully cover
AgentConfig, you might extendtest_agent_config_has_expected_field_typesto include the new field:@pytest.mark.parametrize( "field_name, field_type", [ ("key", str), ("display_name", str), ("command_dir", str), ("command_format", CommandFormat), ("command_file_extension", str), ("detection_dirs", tuple[str, ...]), + ("platform_command_dirs", dict[str, str] | None), ], )Also applies to: 72-80
tests/test_detection.py (1)
5-5: Multi-platform VS Code tests are solid; consider documenting the unknown-platform fallback.The new parametrized tests nicely exercise linux/darwin/win32 detection and
get_command_dir()behavior, and the fallback test withclaude-codeconfirms agents withoutplatform_command_dirsremain backward compatible.If you want to lock in the intended behavior for unexpected
sys.platformvalues, you could add a small extra case that monkeypatchessys.platformto something like"freebsd"and asserts thatget_command_dir()falls back to the defaultcommand_dir. Not required, but it would document the fallback semantics explicitly.Also applies to: 10-10, 64-125

1-217: Task plan matches implemented work; checkbox details could be tidied up.The task list accurately describes the TDD steps and resulting changes in code/tests. If you want to avoid confusion for future readers, you might mark the individual sub-tasks as completed (or add a note that they describe the historical RED/GREEN steps) to align with the
[x]status on the higher-level items.

5-5: I'll help you verify the review comment onslash_commands/config.py. Let me investigate the codebase to validate the suggestions about call site usage and type annotation generalization.
<function_calls>
#!/bin/bashFirst, let's look at the config.py file to understand the structure
head -150 slash_commands/config.py
</function_calls>I need to search the codebase for the information. Let me start:
<function_calls>
#!/bin/bashSearch for command_dir and get_command_dir usage
echo "=== Searching for 'command_dir' usage ==="
rg -n "command_dir" --type=py -B2 -A2echo ""
echo "=== Searching for 'get_command_dir' usage ==="
rg -n "get_command_dir(" --type=py -B2 -A2
</function_calls>Let me also check the imports and type annotations in the config.py file:
<function_calls>
#!/bin/bashCheck the full config.py file first
wc -l slash_commands/config.py
echo "---"
head -30 slash_commands/config.py
</function_calls>Now let me look for the
get_command_dirmethod definition and theplatform_command_dirsfield:
<function_calls>
#!/bin/bashSearch for get_command_dir method definition and platform_command_dirs
ast-grep --pattern $'def get_command_dir($_) {
$$$
}'
</function_calls>Let me use a different approach to find the method:
<function_calls>
#!/bin/bashFind the structure of config.py
grep -n "def get_command_dir|platform_command_dirs|class AgentConfig" slash_commands/config.py
</function_calls>Let me read the full config.py file to understand its structure:
<function_calls>
#!/bin/bash
cat -n slash_commands/config.py
</function_calls>Now let me search for all Python files in the slash_commands directory and how they use these fields:
<function_calls>
#!/bin/bashList all Python files in slash_commands
echo "=== Python files in slash_commands ==="
find slash_commands -name "*.py" -type fecho ""
echo "=== Search for 'command_dir' access patterns ==="

echo "=== Search for Mapping import ==="
rg -n "from typing import|from collections.abc import" --type=py | head -20
</function_calls><available_capabilities>
Let me now check if there are any usages of
Mappingalready in the codebase and verify the typing patterns:
<function_calls>
#!/bin/bashCheck what typing imports are used in config.py
echo "=== Imports in config.py ==="
sed -n '1,20p' slash_commands/config.pyecho ""

echo "=== Check dict[str, str] patterns in config.py ==="
rg -n "dict[str, str]" slash_commands/config.py
</function_calls>Now let me verify how
get_command_dir()is actually being used vs. directcommand_diraccess:
<function_calls>
#!/bin/bashFind all references to command_dir attribute access
echo "=== Detailed search for command_dir usage ==="
rg -n "command_dir" slash_commands/ --type=py -C3echo ""
echo "=== Check if get_command_dir is called anywhere ==="
rg -n "get_command_dir()" slash_commands/ --type=py -C3
</function_calls>Let me focus on finding where AgentConfig is instantiated and used:
<function_calls>
#!/bin/bashFind AgentConfig instantiation and usage
echo "=== AgentConfig references ==="
rg -n "AgentConfig" slash_commands/ --type=pyecho ""
echo "=== Files that might use config ==="
find slash_commands -name "*.py" -type f | xargs -I {} basename {}
</function_calls>Let me look at the entire config.py and any other key files:
<function_calls>
#!/bin/bashGet line count and read config.py
wc -l slash_commands/*.py
echo ""
echo "=== config.py full content ==="
cat slash_commands/config.py
</function_calls>Now let me check if there are VS Code-specific paths or handling in other files:
<function_calls>
#!/bin/bashSearch for VS Code related logic
echo "=== Search for VS Code / vscode references ==="
rg -n -i "vscode|vs.code|vs_code" slash_commands/ --type=py -C2echo ""
echo "=== Search for platform-specific path handling ==="
rg -n "linux|darwin|win32|sys.platform" slash_commands/ --type=py -C2
</function_calls>Let me look at all other files to understand how the config is being used:
<function_calls>
#!/bin/bashList and examine all Python files in slash_commands
for file in slash_commands/*.py; do
echo "=== $file ==="

doneecho ""
echo "=== Content of each file ==="
for file in slash_commands/*.py; do
echo "--- $file ---"
cat "$file"
echo ""
done
</function_calls><available_capabilities>
Based on my investigation of the codebase, let me now verify the key points from the original review comment:
<function_calls>
#!/bin/bashVerify the specific recommendations in the review
echo "=== Checking type annotation in config.py ==="
grep -n "dict[str, str] | None" slash_commands/config.pyecho ""

echo "=== Verify get_command_dir implementation ==="
rg -n "def get_command_dir" slash_commands/ --type=py -A10
</function_calls>Now let me check if there are any test files or integration points that might reveal how this is being used:
<function_calls>
#!/bin/bashSearch for test files
echo "=== Looking for tests ==="
find . -name "test.py" -type f 2>/dev/null | grep -i slash_commands | head -10echo ""
echo "=== Looking for any other Python files that import from config ==="
rg -n "from slash_commands.config import|from .config import" --type=py -C2
</function_calls>Let me check the root directory structure to find test files:
<function_calls>
#!/bin/bashCheck repository structure

echo "=== Files that might use slash_commands ==="
rg -l "slash_commands" --type=py 2>/dev/null | head -20
</function_calls>Let me look for integration points in any main or setup files:
<function_calls>
#!/bin/bashSearch for where AgentConfig.get_command_dir might be used
echo "=== All Python files in repo ==="
find . -name "*.py" -type f 2>/dev/null | grep -v pycache | sortecho ""
echo "=== Search across entire repo for get_command_dir calls ==="
rg -n "get_command_dir" . --type=py
</function_calls><available_capabilities>
Let me verify if this is potentially dead code or if it's actually being used:
<function_calls>
#!/bin/bashCheck git history or PR context - search for where get_command_dir should be called
echo "=== Searching for patterns that might use platform-specific dirs ==="
rg -n "SUPPORTED_AGENTS|AgentConfig|platform_command_dirs" . --type=py -C3 | head -100
</function_calls>Based on my comprehensive investigation of the codebase, I can now rewrite the review comment:
Verify call sites actually invoke
get_command_dir()for VS Code platform-specific paths; the refactoring suggestion aboutMappingis low priority.The
platform_command_dirsfield andget_command_dir()implementation are correctly added toAgentConfig. The method gracefully falls back tocommand_dirwhen the mapping isNoneor lacks a platform key, and theSUPPORTED_AGENTStuple structure correctly wires the VS Code entry withlinux/darwin/win32mappings.However, a search across the repository shows no call sites currently invoking
get_command_dir(). Either:
- This is groundwork for future callers (acceptable for incremental feature work), or
- The refactoring to use this method at relevant call sites still needs to be done.
Confirm whether all production code paths that compute VS Code install directories have been switched to call
AgentConfig.get_command_dir()instead of accessingcommand_dirdirectly.The type annotation suggestion (generalizing to
Mapping[str, str] | None) remains optional—the currentdict[str, str]works fine and is consistent with the codebase's existing style.Mappingis not widely used in slash_commands/, so no immediate change needed unless API flexibility becomes a concern.
| Visual Studio Code stores user data and settings in platform-specific locations: `~/.config/Code` on Linux, `~/Library/Application Support/Code` on macOS, and `%APPDATA%\Code` on Windows. The current VS Code agent detection only checks for the Linux path, which causes detection to fail on macOS and Windows default installations. This spec implements cross-platform path detection and platform-specific command installation directories so slash commands work correctly regardless of the user's OS. | ||

🧩 Analysis chain
pathlib.Path.expanduser() Python environment variables %APPDATA% expansion
<web_search_result>
Short answer: No — Path.expanduser() only expands ~ / ~user (home); it does not expand environment variables like %APPDATA%. To expand %APPDATA% on Windows use os.path.expandvars() (or os.path.expandvars + pathlib). [1][2][3]
Example:
- Using expandvars then Path:
p = Path(os.path.expandvars(r'%APPDATA%\MyApp\config.ini')) # expands %APPDATA%. [2][3]
References:
- pathlib.Path.expanduser docs (mentions only ~ / ~user). [1]
- os.path.expandvars / expanduser docs (expandvars supports %name% on Windows; expanduser handles ~). [2]
- Community note showing use of os.path.expandvars for %APPDATA%. [3]

3 ## Introduction/Overview
4
5 Visual Studio Code stores user data and settings in platform-specific locations: `~/.config/Code` on Linux, `~/Library/Application Support/Code` on macOS, and `%APPDATA%\Code` on Windows. The current VS Code agent detection only checks for the Linux path, which causes detection to fail on macOS and Windows default installations. This spec implements cross-platform path detection and platform-specific command installation directories so slash commands work correctly regardless of the user's OS.
6
7 ## Goals
8
9 - Add detection support for VS Code paths on macOS, Linux, and Windows
10 - Update command installation to use platform-specific directories for each OS
11 - Ensure backward compatibility without requiring migration of existing commands
12 - Provide comprehensive test coverage for all three platforms
13 - Maintain consistency with how other multi-platform agents (like Windsurf) handle path detection
14
15 ## User Stories
16
17 - **As a macOS user**, I want the slash command manager to detect my VS Code installation in the standard macOS location so that I can generate and use slash commands without manual configuration.
18 - **As a Windows user**, I want the slash command manager to detect my VS Code installation in the standard Windows location so that I can use slash commands alongside other agents.
19 - **As a Linux user**, I want the slash command manager to continue detecting my VS Code installation in `~/.config/Code` so that existing configurations remain unaffected.
20 - **As a developer**, I want comprehensive test coverage for all platform paths so that cross-platform detection reliability is verified before releases.
21
22 ## Demoable Units of Work
23
24 ### Unit 1: Test Coverage for Cross-Platform VS Code Detection (TDD - Tests First)
25
26 **Purpose:** Create comprehensive test coverage that verifies VS Code detection works correctly on macOS, Linux, and Windows using mocked `sys.platform` and parametrized tests.
27
28 **Functional Requirements:**
29
30 - The system shall include unit tests with mocked `sys.platform` for macOS, Linux, and Windows detection directories
31 - The system shall verify detection returns empty list when no VS Code directories exist
32 - The system shall verify detection correctly identifies VS Code when platform-specific directories exist
33 - The system shall verify platform-specific paths are correctly resolved (not reversed or mixed)
34 - Tests shall parametrize across all three platforms using `@pytest.mark.parametrize()` with mocked `sys.platform`
35 - Tests shall not rely on actual filesystem operations; all paths are mocked via fixtures
36 - Tests shall verify `get_command_dir()` method returns correct platform-specific paths for each OS
37
38 **Proof Artifacts:**
39
40 - Test file: `tests/test_detection.py` includes new parametrized tests for platform-specific VS Code detection demonstrates test coverage
41 - Test output: `pytest tests/test_detection.py -v -k "vs_code"` shows all platform-specific tests passing demonstrates test execution
42 - Coverage report: `pytest tests/test_detection.py --cov=slash_commands.detection --cov-report=term-missing` shows test paths exercised demonstrates coverage
43 - Test failures: Initially failing tests (before implementation) demonstrate tests are written first, then code implements to pass
44
45 ### Unit 2: Extend AgentConfig with Platform-Aware Command Directory Support (TDD - Implementation)
46
47 **Purpose:** Implement the `AgentConfig` dataclass extension to support platform-specific command directories, making tests from Unit 1 pass.
48
49 **Functional Requirements:**
50
51 - The system shall add optional `platform_command_dirs: dict[str, str] | None` field to `AgentConfig` dataclass
52 - The system shall implement `get_command_dir()` method that returns platform-appropriate path using `sys.platform`
53 - The system shall default to single `command_dir` for agents without `platform_command_dirs` (backward compatible)
54 - The method shall return correct paths: Linux `.config/Code/User/prompts`, macOS `Library/Application Support/Code/User/prompts`, Windows `AppData/Roaming/Code/User/prompts`
55 - Path handling shall use `pathlib.Path` for cross-platform compatibility
56
57 **Proof Artifacts:**
58
59 - Code diff: `slash_commands/config.py` shows `platform_command_dirs` field added to `AgentConfig` demonstrates field extension
60 - Code diff: `slash_commands/config.py` shows `get_command_dir()` method implementation demonstrates platform resolution logic

62 - CLI: `python -c "from slash_commands.config import get_agent_config; import sys; cfg = get_agent_config('vs-code'); print(cfg.get_command_dir())"` returns platform-appropriate path demonstrates method works
63
64 ### Unit 3: Update VS Code Agent Configuration with Multi-Platform Paths (TDD - Implementation)
65
66 **Purpose:** Update the VS Code agent configuration in `_SUPPORTED_AGENT_DATA` to detect all three platforms and install commands to platform-specific directories.
67
68 **Functional Requirements:**
69
70 - The system shall update VS Code agent `detection_dirs` tuple to include all three platform paths
71 - The system shall add `platform_command_dirs` dictionary mapping `sys.platform` values to command installation paths
72 - The system shall maintain existing detection order and priority from `SUPPORTED_AGENTS`
73 - The system shall continue supporting existing Linux installations without migration
74 - Detection directories: Linux `.config/Code`, macOS `Library/Application Support/Code`, Windows `AppData/Roaming/Code`
75 - Installation paths: Linux `.config/Code/User/prompts`, macOS `Library/Application Support/Code/User/prompts`, Windows `AppData/Roaming/Code/User/prompts`
76
77 **Proof Artifacts:**
78
79 - Code diff: `slash_commands/config.py` shows VS Code agent tuple updated with all three platform paths demonstrates configuration change
80 - CLI: `python -c "from slash_commands.config import get_agent_config; cfg = get_agent_config('vs-code'); print('Detection:', cfg.detection_dirs); print('Commands:', cfg.platform_command_dirs)"` shows all platform paths configured demonstrates configuration completeness
81 - Test output: `pytest tests/ -v` shows all tests passing including backward compatibility tests demonstrates no regressions
82
83 ### Unit 4: Verify Cross-Platform Integration and Backward Compatibility
84
85 **Purpose:** Verify end-to-end that VS Code detection and command installation works across all platforms and that existing Linux installations remain unaffected.
86
87 **Functional Requirements:**
88
89 - The system shall detect VS Code on all three platforms when appropriate directories exist
90 - The system shall install commands to the correct platform-specific directory
91 - The system shall maintain backward compatibility with existing Linux installations
92 - All existing tests shall pass without modification or migration
93
94 **Proof Artifacts:**
95
96 - CLI: `slash-man generate --list-agents` succeeds and includes `vs-code` with correct display name demonstrates agent detection works end-to-end
97 - CLI: `slash-man generate --agent vs-code --dry-run` shows commands would install to correct platform-specific path demonstrates installation path resolution
98 - Test output: `pytest tests/ -v` shows all tests passing including existing tests demonstrates backward compatibility maintained
99 - Coverage: `pytest tests/ --cov=slash_commands --cov-report=term-missing` shows 100% coverage on modified code demonstrates comprehensive testing
100
101 ## Non-Goals (Out of Scope)
102
103 1. **User migration tooling**: This spec does not include automatic migration of existing commands from `~/.config/Code/User/prompts` to platform-specific paths. Users on non-Linux platforms will need to manually regenerate commands after updating.
104 2. **VS Code settings sync**: This spec does not address VS Code's cloud settings sync functionality or how it interacts with command storage locations.
105 3. **Environment variable configuration**: This spec does not add support for user-configurable paths via environment variables; paths are platform-determined only.
106 4. **GitHub Actions/CI platform detection**: This spec focuses on user machines (macOS, Linux, Windows) and does not address CI environment-specific paths.
107
108 ## Design Considerations
109
110 No specific UI/UX or visual design changes are required for this feature. The implementation is transparent to end users—they will simply see VS Code detected and commands installed to the correct location. The CLI output remains the same; only the underlying path logic changes.
111
112 ## Repository Standards
113
114 Based on the codebase review and AGENTS.md:
115
116 - **Code style**: Follow existing Python conventions in `slash_commands/config.py` and `slash_commands/detection.py`
117 - **Data structures**: Use tuple-based configuration pattern from `_SUPPORTED_AGENT_DATA` in `config.py`
118 - **Testing**: Follow pytest patterns used in `tests/test_detection.py` with fixtures and parametrized tests
119 - **Test execution**:
120 - Unit tests: `uv run pytest tests/ -v -m "not integration"` (excludes integration tests)
121 - Integration tests: `uv run scripts/run_integration_tests.py` (ALWAYS use this script, NEVER run directly with pytest - runs in Docker to prevent overriding user prompt files)
122 - **Python execution**: ALWAYS use `uv run` prefix for all Python commands (e.g., `uv run pytest`, `uv run python -c`)
123 - **Path handling**: Use `pathlib.Path` for cross-platform compatibility (already used in `detection.py`)
124 - **Naming**: Use underscore-prefixed names for private functions (`_agent_configured`)
125 - **Type hints**: Include type annotations for all functions and parameters
126 - **Commit messages**: Follow Conventional Commits pattern (e.g., `fix(config): add cross-platform VS Code path support`)
127 - **Dependency management**: Use `uv sync` for installing/updating dependencies; never manually edit dependency files
128
129 ## Technical Considerations
130
131 - **Platform detection**: Use `sys.platform` (not `platform.system()`) because it's determined at compile time with well-defined values: `'linux'`, `'darwin'` (macOS), and `'win32'` (Windows). This is faster and more reliable than runtime system calls.
132 - **Path resolution**: Windows paths use environment variable expansion (`%APPDATA%`) while Unix paths use tilde expansion (`~`). Python's `pathlib.Path` with `expanduser()` handles both automatically.
133 - **Detection directories**: Update the `detection_dirs` tuple in `AgentConfig` to include all three platform paths:
134 - Linux: `.config/Code`
135 - macOS: `Library/Application Support/Code`
136 - Windows: `AppData/Roaming/Code`
137 - **Command directory logic**: Extend `AgentConfig` dataclass with platform-specific command directories:
138 - Add optional `platform_command_dirs: dict[str, str]` field to map `sys.platform` values to command installation paths
139 - Implement `get_command_dir()` method that returns the platform-appropriate path
140 - VS Code config specifies all three paths; other agents continue using single `command_dir` (backward compatible)
141 - **Testing approach**: Mock `sys.platform` using `monkeypatch.setattr()` rather than filesystem operations. Use `@pytest.mark.parametrize()` to test all three platform paths in a single test run on any host OS. This enables comprehensive cross-platform testing without requiring multiple machines or OS-specific test runners.
142 - **Tilde and environment variable expansion**: Defer expansion to point-of-use (generation time) so that `~/` and `%APPDATA%` are resolved when commands are actually being generated, not during detection.

Correct line 132: expanduser() does not expand %APPDATA% automatically.
The spec claims at line 132 that "pathlib.Path with expanduser() handles both automatically" for tilde (~) and environment variables (%APPDATA%). This is inaccurate. Verification confirms that expanduser() expands only ~ and ~user patterns; Windows environment variables like %APPDATA% require os.path.expandvars().
Suggested fix: Revise line 132 from:
Python's
pathlib.Pathwithexpanduser()handles both automatically.
To:
Python's
pathlib.Path.expanduser()handles tilde expansion (~); Windows%APPDATA%requiresos.path.expandvars(). Both can be chained:Path(os.path.expandvars(path)).expanduser().
Line 142 correctly defers expansion to point-of-use, but the mechanism in line 132 needs clarification to avoid implementation mistakes.
Also applies to: 51-56 (context only, no errors), 131-143 (lines 131, 141 are correct; line 132 is the issue)

around lines 131-143: line 132 incorrectly states that pathlib.Path.expanduser()
handles both tilde and Windows environment variables; update that sentence to
explicitly state that expanduser() only expands ~ and ~user, that Windows %VAR%
requires os.path.expandvars(), and suggest the correct approach (call
os.path.expandvars() then Path(...).expanduser() at point-of-use). Keep line
142's deferral to point-of-use but clarify the mechanism as described so
implementers won't rely solely on expanduser() for %APPDATA%.
The get_command_dir() method was implemented but never actually called. All code paths were still using agent.command_dir directly, which broke cross-platform VS Code path resolution on macOS and Windows. Changes: - Update writer.py to use get_command_dir() (3 locations) - Update cli.py --list-agents display to use get_command_dir() - Update generators.py metadata to use get_command_dir() - Add platform_command_dirs field type test to test_config.py - Add unknown platform fallback test (freebsd) to test_detection.py - Fix grammar: "VS Code related" → "VS Code-related" in docs 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

320-325: Inconsistent use ofcommand_dirvsget_command_dir()causes wrong write location
SlashCommandWriternow detects and searches usingagent.get_command_dir():
_find_existing_files:self.base_path / agent.get_command_dir() / filenamefind_generated_files:self.base_path / agent.get_command_dir()But
_generate_filestill writes toself.base_path / agent.command_dir / filename. On agents withplatform_command_dirs(e.g., VS Code on macOS/Windows), this means:
- Files are written into the default (Linux)
command_dir.- Existence checks, cleanup, and discovery run against the platform-specific directory, so they won’t see those files.
This is a correctness bug on non-Linux platforms.
Suggested fix:
- filename = self._sanitize_filename(prompt.name, agent.command_file_extension) - output_path = self.base_path / agent.command_dir / filename + filename = self._sanitize_filename(prompt.name, agent.command_file_extension) + output_path = self.base_path / agent.get_command_dir() / filenameThis will align generation, detection of existing files, and cleanup across all platforms and agents.

73-81: Detection-dir invariants are reasonable but somewhat rigidThe new checks on
agent.detection_dirsmatch current needs (hidden dirs plus VS Code’sLibrary/AppDatapaths). If you later add agents with other non-hidden roots, this test will need updating; for now it’s fine and makes assumptions explicit.docs/specs/07-spec-vs-code-macos-detection/07-tasks-vs-code-macos-detection.md (1)
1-217: Spec accurately reflects the implemented VS Code cross-platform behaviorThe task doc lines up with the actual design (
platform_command_dirs,get_command_dir(), updated config/tests) and gives a clear TDD narrative. Only minor nit is that some subtasks remain unchecked despite being implemented, but that’s purely cosmetic.

- Validate each VS Code detection directory independently across linux/darwin/win32.
- Exercise

Update README.md and slash-command-generator.md to document platform-specific VS Code installation directories for Linux, macOS, and Windows. The generator automatically detects the platform and installs commands to the correct location.
Fix bug where VS Code commands were written to Linux path on macOS and Windows. The _generate_file() method was using agent.command_dir directly instead of agent.get_command_dir(), causing incorrect platform-specific path resolution. Changes: - Update writer.py _generate_file() to use get_command_dir() - Fix test_generators.py assertion to match actual generator output - Fix integration test to verify platform-specific paths - Add parametrized test for VS Code platform-specific path writing Fixes issue where existing files in Linux location caused new files to be written to Linux path instead of platform-specific path.

tests/test_writer.py (1)
851-887: VS Code writer test cleanly verifies platform-specific output pathsThis parametrized test does a solid job of asserting that VS Code prompts are written under the expected per-platform directories and that the writer’s result metadata matches the actual path and agent. Using
monkeypatch.setattr(sys, "platform", platform_value)ensuresAgentConfig.get_command_dir()sees the right platform without leaking state across tests.If you ever want to tighten coupling with the config, you could also assert
expected_dir == get_agent_config("vs-code").get_command_dir()for eachplatform_value, but the current explicit mapping is perfectly fine and clearer for this test’s purpose.

190-207: VS Code platform-specific paths are accurate and aligned with implementationThe table entry and note correctly describe the per-platform VS Code prompt directories and the fact that the generator chooses the directory based on the current platform. This matches the new
AgentConfig.get_command_dir()+platform_command_dirsbehavior and keeps docs in sync with the code.tests/test_writer.py (1)
5-5: Importingsysis appropriate for platform monkeypatchingThe new
sysimport is necessary formonkeypatch.setattr(sys, "platform", ...)in the VS Code writer test and is scoped correctly here.tests/test_generators.py (1)
60-66: Switch toagent.get_command_dir()keeps test aligned with platform-aware configAsserting
meta["command_dir"] == agent.get_command_dir()is the right update now that command directories can vary by platform. This keeps the test consistent with the public API and future-proof against platform-specific mappings.tests/integration/test_generate_command.py (1)
248-253: Integration test now correctly relies onget_command_dir()Using
agent_config.get_command_dir()to buildexpected_dirmatches the new platform-aware behavior and ensures this integration test validates the same directory resolution logic the CLI/writer use at runtime.
Replace substring matching with pathlib.Path().parts to validate that 'Library' and 'AppData' appear as actual path components rather than substrings. This prevents false positives like 'my_library' or 'myAppData' from passing validation. Addresses CodeRabbit review feedback about overly permissive validation logic.

tests/test_config.py (2)
32-47: Field-type assertion forplatform_command_dirsis precise and consistentThe addition of
("platform_command_dirs", dict[str, str] | None)keeps the type expectations in sync with the newAgentConfigfield and maintains the existing pattern of strict type equality checks. This is tight coupling to the exact annotation (as opposed to e.g.Mapping[str, str]), but matches the PR’s declared public API and is fine as long as we treat that annotation as part of the contract.If you ever want to relax this later, consider asserting on a
typing.get_origin/get_argsdecomposition instead of direct equality so minor annotation refactors (e.g.,Mapping[str, str] | None) don’t break the test.
74-87: Detection dir invariants are correct but a bit rigid and OS-dependentThe new checks correctly capture the intended constraints (hidden roots or macOS/Windows-specific roots via
Library/AppDatapath components), and they should work as long as alldetection_dirsare normalized with forward slashes and without env-var markers (e.g.,%APPDATA%). Two minor robustness thoughts:
Path(dir_)is host-OS specific: on non-Windows CI, a Windows-style string using backslashes would be seen as a single component. That means future additions like"AppData\\Roaming\\Code"would unexpectedly fail this invariant even though they’re logically OK.- The invariant is quite prescriptive; adding a new agent that legitimately needs a non-hidden, non-Library/AppData root (or a different Windows env-var style) will require changing this test.
These aren’t blockers today, but you might consider in the future:
- Using a
PurePosixPath/manual split on both"/"and"\\"to decouple from host OS, and/or- Extracting this logic into a small helper so future exceptions are easier to express in one place.
If you expect any
detection_dirsto use backslashes or env-var tokens (like%APPDATA%/Code), please double-check that they still pass this assertion.

7-7: Path import usage looks appropriate
Pathis used below to reason about path components for detection dirs; import is minimal and justified.
Why?
VS Code stores user data in platform-specific locations:
~/.config/Codeon Linux,~/Library/Application Support/Codeon macOS, and%APPDATA%\Codeon Windows. The VS Code agent detection only checked the Linux path, causing detection to fail on macOS and Windows default installations. This prevented macOS and Windows users from using slash commands with VS Code.Evidence: Spec document
07-spec-vs-code-macos-detection.md(commitb75125b), implementation commitf47a2c4with 10 new parametrized tests.What Changed?
