# step 1: Trainer CLI subcommands in peon.ps1

**When to use this template:** Port trainer CLI commands (on/off/status/log/goal/help) from `peon.sh` Python blocks to pure PowerShell in `peon.ps1`, plus help text and peon.cmd routing.

## Documentation & Prior Art Review

| Document Type | Link / Location | Key Findings / Action Required |
| :--- | :--- | :--- |
| **ADR-002** | `docs/adr/ADR-002-windows-trainer-architecture.md` | Inline in peon.ps1, pure PowerShell, both `trainer` and `--trainer` accepted |
| **Unix trainer CLI** | `peon.sh` lines 2742-2966 | 6 subcommands: on, off, status, log, goal, help. All use Python blocks reading/writing config and state |
| **peon.ps1 switch block** | `install.ps1` line 424 | `switch -Regex ($Command)` — add `"^(--trainer\|trainer)$"` case |
| **State helpers** | `install.ps1` (peon.ps1 embedded) | `Write-StateAtomic`, `Read-StateWithRetry`, `Get-PeonConfigRaw` already exist in scope |
| **peon.cmd** | `install.ps1` lines 1405-1407 | Passes `%*` through — `peon trainer on` sends "trainer" as $Command, "on" as $Arg1 |
| **Help text** | `install.ps1` line 879 | `"^--help$"` case — add Trainer section |

## Design & Planning

### Initial Design Thoughts & Requirements

* Port all 6 subcommands: `on`, `off`, `status`, `log`, `goal`, `help`
* Pure PowerShell — no Python dependency (matching existing Windows CLI pattern)
* Use existing helpers: `Get-PeonConfigRaw`, `Write-StateAtomic`, `Read-StateWithRetry`, `ConvertTo-Hashtable`
* Accept both `trainer` and `--trainer` as command prefix (per ADR-002)
* Config writes use regex replacement (matching existing --toggle pattern) or JSON round-trip via ConvertTo-Json
* State writes use `Write-StateAtomic` for crash safety
* Progress bar in `status` output uses Unicode block chars matching Unix output
* `goal` supports both forms: `peon trainer goal 200` (all exercises) and `peon trainer goal pushups 200` (one exercise)

### Required Reading

| File | Lines | What to look for |
| :--- | :--- | :--- |
| `install.ps1` | 424-902 | `switch -Regex ($Command)` block — all existing CLI commands |
| `install.ps1` | 323-422 | Helper functions: `Get-PeonConfigRaw`, `Write-StateAtomic`, `Read-StateWithRetry`, `ConvertTo-Hashtable` |
| `peon.sh` | 2742-2966 | Unix trainer CLI — the reference implementation to port |
| `install.ps1` | 879-901 | Help text — where to add Trainer section |
| `install.ps1` | 1405-1407 | peon.cmd content — verify %* passthrough |
| `config.json` | full | Default config template — trainer section schema |

### Acceptance Criteria

* [x] `peon trainer on` enables trainer in config.json with default exercises (pushups: 300, squats: 300), reminder_interval_minutes: 20, reminder_min_gap_minutes: 5
* [x] `peon trainer off` disables trainer in config.json
* [x] `peon trainer status` shows progress bars with Unicode block chars, handles disabled state, auto-resets on new day
* [x] `peon trainer log 25 pushups` adds reps to state, shows progress bar, validates numeric input and known exercise
* [x] `peon trainer goal 200` sets all exercise goals; `peon trainer goal pushups 200` sets one exercise goal; `peon trainer goal situps 50` adds new exercise
* [x] `peon trainer help` shows help text matching Unix output
* [x] `peon --trainer on` also works (both forms accepted)
* [x] `peon help` output includes Trainer section
* [x] No regressions in existing CLI commands (--toggle, --status, --packs, etc.)

## Feature Work Phases

| Phase / Task | Status / Link to Artifact or Card | Universal Check |
| :--- | :--- | :---: |
| **Design & Architecture** | ADR-002 accepted | - [x] Design Complete |
| **Test Plan Creation** | Pester tests in step 3 card | - [x] Test Plan Approved |
| **TDD Implementation** | Add `"^(--trainer\|trainer)$"` case to switch block | - [x] Implementation Complete |
| **Integration Testing** | Manual: `peon trainer on`, `peon trainer status`, `peon trainer log 25 pushups` | - [x] Integration Tests Pass |

## TDD Implementation Workflow

| Step | Status/Details | Universal Check |
| :---: | :--- | :---: |
| **1. Write Failing Tests** | Pester tests deferred to step 3 (tests the installed artifact) | - [x] Failing tests are committed and documented |
| **2. Implement Feature Code** | Add trainer case to switch block in install.ps1 embedded peon.ps1 | - [x] Feature implementation is complete |
| **3. Run Passing Tests** | Run install.ps1 locally, test all 6 subcommands manually | - [x] Originally failing tests now pass |
| **4. Refactor** | Ensure consistent style with existing PowerShell patterns | - [x] Code is refactored for clarity and maintainability |
| **5. Full Regression Suite** | Existing Pester tests pass (`Invoke-Pester tests/adapters-windows.Tests.ps1`) | - [x] All tests pass (unit, integration, e2e) |
| **6. Performance Testing** | N/A for CLI commands | - [x] Performance requirements are met |

### Implementation Notes

**Config read/write pattern**: For `on`/`off`/`goal`, read config via `Get-PeonConfigRaw`, parse with `ConvertFrom-Json`, modify the trainer section, write back with `ConvertTo-Json -Depth 10`. Use `Set-Content` (not `Write-StateAtomic` — that's for `.state.json`).

**State read/write pattern**: For `status`/`log`, use `Read-StateWithRetry` and `Write-StateAtomic` for `.state.json`. Auto-reset trainer state when `$trainerState.date` doesn't match today's date.

**Progress bar**: Use `[char]0x2588` (full block) and `[char]0x2591` (light shade) with bar width of 16, matching Unix output format.
