# step 4B: Debug and logs CLI parity in peon.ps1

## Feature Overview & Context

* **Associated Ticket/Epic:** PRD-002 Phase 2 — "CLI commands" (Windows parity)
* **Feature Area/Component:** peon.ps1 CLI (embedded in install.ps1 $hookScript), peon.cmd
* **Target Release/Milestone:** v2/m4 "When something breaks, you can see why"

**Required Checks:**
* [x] **Associated Ticket/Epic** link is included above.
* [x] **Feature Area/Component** is identified.
* [x] **Target Release/Milestone** is confirmed.

## Documentation & Prior Art Review

* [x] `README.md` or project documentation reviewed.
* [x] Existing architecture documentation or ADRs reviewed.
* [x] Related feature implementations or similar code reviewed.
* [x] API documentation or interface specs reviewed [if applicable].

| Document Type | Link / Location | Key Findings / Action Required |
| :--- | :--- | :--- |
| **Design Doc** | docs/designs/structured-hook-logging.md | Lines 407-438: CLI spec. Windows CLI stays inline in install.ps1. |
| **install.ps1** | install.ps1 $hookScript CLI section | Existing switch block handles peon subcommands (status, volume, packs, etc.). Add debug and logs cases. |
| **step 4A card** | kt3ucx | Unix CLI implementation — defines the command interface this card mirrors. |
| **PRD-002** | Branch docs/prd-002-hook-observability | Phase 2 launch criteria: identical behavior on Windows. |

## Design & Planning

### Initial Design Thoughts & Requirements

* `peon debug on/off` — read config.json with `ConvertFrom-Json`, set `debug` property, write back with `ConvertTo-Json`.
* `peon debug status` — read config, report state, list log dir contents.
* `peon logs` — `Get-Content` on today's log file, last 50 lines.
* `peon logs --last N` — `Get-Content` with `-Tail N` across log files sorted by date descending.
* `peon logs --session ID` — `Select-String -Pattern "session=$ID"` across today's log.
* `peon logs --clear` — `Remove-Item` all files in logs directory.
* All commands added to the switch block in the embedded $hookScript.

### Acceptance Criteria

- [x] `peon debug on` sets `debug: true` in config.json on Windows
- [x] `peon debug off` sets `debug: false`
- [x] `peon debug status` shows debug state, log directory, file count, total size
- [x] `peon logs` shows last 50 lines of today's log
- [x] `peon logs --last N` shows last N lines across all logs
- [x] `peon logs --session ID` filters by session ID
- [x] `peon logs --clear` deletes all log files
- [x] `peon help` lists debug and logs on Windows
- [x] Commands accessible via `peon.cmd` wrapper
- [x] Pester tests for each CLI command
* [x] Output format matches Unix peon.sh CLI output (step 4A not yet implemented; Windows defines the reference output format per design doc)

## Feature Work Phases

| Phase / Task | Status / Link to Artifact or Card | Universal Check |
| :--- | :--- | :---: |
| **Design & Architecture** | Mirror step 4A Unix CLI interface | - [x] Design Complete |
| **Test Plan Creation** | Pester tests for all debug/logs subcommands | - [x] Test Plan Approved |
| **TDD Implementation** | Switch cases + help text in $hookScript | - [x] Implementation Complete |
| **Integration Testing** | End-to-end on Windows: debug on → event → logs | - [x] Integration Tests Pass |
| **Documentation** | Covered by step 5 card | - [x] Documentation Complete |
| **Code Review** | Sprint reviewer | - [x] Code Review Approved |
| **Deployment Plan** | Users re-run install.ps1 or peon update | - [x] Deployment Plan Ready |

## TDD Implementation Workflow

| Step | Status/Details | Universal Check |
| :---: | :--- | :---: |
| **1. Write Failing Tests** | Pester: debug on/off modifies config; debug status reports correctly; logs reads today's file; logs --last N; logs --session filters; logs --clear deletes | - [x] Failing tests are committed and documented |
| **2. Implement Feature Code** | Add debug and logs switch cases to $hookScript in install.ps1. Update peon help output. | - [x] Feature implementation is complete |
| **3. Run Passing Tests** | New + existing Pester tests pass | - [x] Originally failing tests now pass |
| **4. Refactor** | N/A | - [x] Code is refactored for clarity and maintainability |
| **5. Full Regression Suite** | Full Pester suite green | - [x] All tests pass (unit, integration, e2e) |
| **6. Performance Testing** | N/A | - [x] Performance requirements are met |

### Implementation Notes

**Required Reading:**

| File | Lines | Purpose |
| :--- | :--- | :--- |
| `install.ps1` | $hookScript CLI section | Add debug/logs switch cases |
| `install.ps1` | help output section | Add debug/logs command descriptions |
| `tests/adapters-windows.Tests.ps1` | full | Add Pester tests |

**Dependencies:** step 3 (w56sog) must complete first (log files must exist on Windows). Can run in parallel with step 4A.

## Validation & Closeout

| Task | Detail/Link |
| :--- | :--- |
| **Code Review** | TBD |
| **QA Verification** | TBD |
| **Staging Deployment** | N/A |

## Executor Work Log (Cycle 1)

Implemented debug and logs CLI commands in peon.ps1 (commit 65aaad1):

**1. `peon debug on/off/status` commands:**
- `debug on`: reads config.json via ConvertFrom-Json, sets `debug = $true`, writes back with InvariantCulture for decimal safety
- `debug off`: same pattern, sets `debug = $false`
- `debug status`: reports enabled/disabled, log directory path, file count, total size (with KB/MB formatting)
- Default subcommand (no arg) falls back to `status`
- Unknown subcommands show usage help

**2. `peon logs` commands:**
- `logs` (no args): shows last 50 lines of today's log file (`peon-ping-YYYY-MM-DD.log`)
- `logs --last N`: collects lines across all log files in chronological order (oldest first), returns last N
- `logs --session ID`: filters today's log for lines matching `session=ID`
- `logs --clear`: deletes all `peon-ping-*.log` files in the logs directory
- Helpful messages when no logs exist (suggests `peon debug on`)
- Unknown flags show usage help

**3. Help text updated:**
- Added "Debug & Logs" section to `peon --help` output listing all debug and logs subcommands

**4. Pester tests (27 tests, all pass):**
- `tests/debug-logs-windows.Tests.ps1`:
  - debug on: sets config, outputs confirmation, idempotent (3 tests)
  - debug off: sets config, outputs confirmation (2 tests)
  - debug status: disabled/enabled state, log dir, file count, zero files, default subcommand (6 tests)
  - logs (today): last 50 lines, fewer than 50, no log files message (3 tests)
  - logs --last N: across files, default 50, no files message (3 tests)
  - logs --session: filters by ID, not found, no ID usage (3 tests)
  - logs --clear: deletes files, no files message (2 tests)
  - help: lists debug and logs commands (2 tests)
  - unknown flag/subcommand: shows usage (2 tests)
  - config preservation: debug on does not destroy other keys (1 test)

**5. Regression testing:**
- All 360 existing adapters-windows.Tests.ps1 tests pass
- All 29 hook-logging-windows.Tests.ps1 tests pass

**Note:** "Output format matches Unix peon.sh CLI output" -- step 4A (Unix CLI) is not yet implemented. The Windows implementation defines the reference output format based on the design doc spec. Step 4A should mirror this.

Verdict: APPROVAL. No blockers. 2 non-blocking follow-up items:
- L1 (planner): Extract `Set-PeonConfig` helper to DRY 8 culture-swap + config-write sites in install.ps1
- L2 (close-out): Add graceful error handling for `peon logs --last` with non-numeric argument

Routed to:
- Executor: `.gitban/agents/executor/inbox/HOOKLOG-unkjkl-executor-1.md` (close-out + L2 fix)
