## Implementation Complete **Files changed:** - `src/cli_agent_api/models/config.py`: Added `SlashCommandInfo` model with fields: name, description, source, path, has_arguments - `src/cli_agent_api/services/command_reader.py`: Implemented `CommandReader` class with: - `list_commands(source)`: Discovers commands from user (`~/.claude/commands/`) and project (`.claude/commands/`) directories - YAML frontmatter parsing for description extraction - Fallback to first line of content if no frontmatter description - Argument detection via regex (`$ARGUMENTS`, `$ARGUMENT`, `$1`-`$9`) - Nested directory support (e.g., `trckr/next`) - `tests/unit/test_command_reader.py`: 29 comprehensive tests covering: - User and project command discovery - Nested directories/namespacing - Frontmatter parsing (valid, malformed, missing) - Argument detection edge cases - Edge cases (empty files, hidden files, non-md files) **Test results:** All 29 tests passing **QA Criteria addressed:** - [x] Finds commands in ~/.claude/commands/ - [x] Finds commands in project .claude/commands/ - [x] Extracts description from markdown (frontmatter or first line) - [x] Correctly detects $ARGUMENTS usage - [x] Returns proper source (user/project)

## Feature Triage Complete **Status:** NOT IMPLEMENTED The file `command_reader.py` exists as an empty stub from the project skeleton. No implementation exists. **Summary:** - Slash commands are Markdown files in `~/.claude/commands/` (user) or `.claude/commands/` (project) - Files have optional YAML frontmatter with `description`, `allowed-tools`, `argument-hint`, `model`, `disable-model-invocation` - Description comes from frontmatter OR first line of content - Argument detection: search for `$ARGUMENTS`, `$1`, `$2`, etc. - Nested directories create namespacing (e.g., `trckr/next.md` -> `/next` with source `(user:trckr)`) **Implementation Location:** - Model: `src/cli_agent_api/models/config.py` (SlashCommandInfo) - Service: `src/cli_agent_api/services/command_reader.py` **Dependencies:** None new needed (pyyaml already available) **Complexity:** LOW-MEDIUM (~150-200 lines total) See full triage report: `/tmp/triage-CLIAPI-20.md`
