name	vp-rollback
description	Rollback to any checkpoint safely with state preservation
version	0.1.1

## Invocation Banner

Output this banner as the first thing on every invocation — before questions, work, or any other output:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 VIEPILOT ► VP-ROLLBACK  v0.1.1 (fw 2.19.0)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

## Version Update Check (ENH-072)

After displaying the greeting banner, run:

node "$HOME/.claude/viepilot/bin/vp-tools.cjs" check-update --silent

If exit code = 1 (update available — new version printed to stdout): Display notice banner before any other output:

┌──────────────────────────────────────────────────────────────────┐
│ ✨ ViePilot {latest_version} available  (installed: {current})   │
│    npm i -g viepilot && vp-tools install --target {adapter_id}   │
└──────────────────────────────────────────────────────────────────┘

Replace {latest_version} with stdout from the command, {current} with the installed version, {adapter_id} with the active adapter (claude-code / cursor / antigravity / codex / copilot).

If exit code = 0 or command unavailable: silent, continue.

Suppression rules:

• --no-update-check flag on skill invocation → skip this step entirely
• config.json → update.check: false → skip this step entirely
• Show at most once per session (update_check_done session guard) </version_check> <persona_context>

Persona Context Injection (ENH-073)

At skill start, run:

node "$HOME/.claude/viepilot/bin/vp-tools.cjs" persona auto-switch
node "$HOME/.claude/viepilot/bin/vp-tools.cjs" persona context

Inject the output as ## User Persona context before any task execution. Silent if command unavailable or errors. </persona_context>

## A. Skill Invocation - Skill được gọi khi user mention `vp-rollback`, `/vp-rollback`, "rollback", "quay lại" - Treat all user text after the skill mention as `{{VP_ARGS}}`

B. User Prompting

Show available checkpoints and confirm before rollback.

C. Tool Usage

Use Claude Code tools: Bash (shell), Read (file), Edit + Write (file write/patch), Grep (search), Glob (file patterns), LS, WebSearch, WebFetch, Agent (spawn subagent — multi-level nesting supported) Interactive: AskUserQuestion (deferred — preload via ToolSearch before first call)

## A. Skill Invocation Same trigger keywords as claude-code adapter.

C. Tool Usage

Use Cursor tools: run_terminal_cmd (shell), read_file (read), edit_file (write/edit), grep_search (search), web_search, codebase_search, list_dir, file_search Interactive: text list fallback (AskQuestion available in Plan Mode only; Agent Mode = text) Subagent: /multitask (user command, single-level only — not a callable tool) MCP limit: 40 tools

## A. Skill Invocation Same trigger keywords as claude-code adapter. Skill discovery: LLM-driven (automatic, no slash command needed).

C. Tool Usage

Use Antigravity tools: shell (cmd), file_read, file_write, MCP plugins Interactive: text fallback (TUI-based; no formal AskUserQuestion) Skill path: .agents/skills/<skill>/SKILL.md (project) or ~/.gemini/antigravity/skills/ (global) Note: Gemini CLI deprecated June 18, 2026 — use Antigravity CLI.

## A. Skill Invocation Same trigger keywords as claude-code adapter.

C. Tool Usage

Use Codex tools: container.exec (sandboxed shell), apply_patch (file write), web_search Interactive: text fallback (TUI Tab/Enter injection) Config: ~/.codex/config.toml

## A. Skill Invocation Same trigger keywords as claude-code adapter. Discovery: User-driven (`@agent-name` in GitHub Copilot Chat).

C. Tool Usage

Use Copilot tools: runCommands (shell), read/readfile (read), edit/editFiles (write), code_search, find_references Interactive: askQuestions (main agent only — NOT available in subagents; VS Code issue #293745) Skill path: .github/agents/<name>.agent.md <scope_policy>

ViePilot Namespace Guard (BUG-004)

• Default mode: only use and reference vp-* skills in ViePilot workflows.
• External skills (non vp-*) are out of framework scope unless user explicitly opts in.
• If external skills appear in runtime context, ignore them and route with the closest built-in vp-* skill. </scope_policy>

<implementation_routing_guard>

Implementation routing guard (ENH-021)

• Checkpoint / revert — does not replace /vp-auto for new work; after rollback use /vp-evolve / /vp-auto per workflow. See workflows/request.md. </implementation_routing_guard>

Rollback to any checkpoint safely, with backup and state preservation.

Checkpoints: Git tags with prefix vp-

• vp-p{N}-t{M} - Start of task M in phase N
• vp-p{N}-t{M}-done - Task M complete
• vp-p{N}-complete - Phase N complete

Safety:

• Backup current state before rollback
• Validate target checkpoint exists
• Update HANDOFF.json after rollback

<execution_context> @$HOME/{envToolDir}/workflows/rollback.md </execution_context>

Optional flags: - `--list` : List available checkpoints (plain-text table, no interactive prompt) - `--to ` : Rollback to specific tag - `--latest` : Rollback to latest checkpoint - `--force` : Skip confirmation - `--dry-run` : Show what would happen - `--limit N` : Checkpoints per page in interactive selection (default: 10). E.g. `--limit 30` shows 30 per page.

1. List Checkpoints

git tag -l "vp-*" --sort=-creatordate

Display with dates and descriptions:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 AVAILABLE CHECKPOINTS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 TAG                    DATE         COMMIT
 vp-p1-complete         2026-03-30   Phase 1 done
 vp-p1-t1-done          2026-03-30   Task 1.1 done
 vp-p1-t1               2026-03-30   Start task 1.1
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

2. Validate Target

• Check tag exists
• Show files that will change
• Show commits that will be undone

3. Backup Current State

# Backup HANDOFF.json
cp .viepilot/HANDOFF.json .viepilot/HANDOFF.backup.json

# Create safety tag
git tag vp-backup-{timestamp}

4. Execute Rollback

# Reset to checkpoint
git reset --hard {tag}

# Or soft reset (keep changes staged)
git reset --soft {tag}

5. Update State

Update HANDOFF.json to reflect rollback position. Update TRACKER.md if needed.

6. Confirm Success

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 ROLLBACK COMPLETE ✓
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

 From: {previous_commit}
 To:   {tag} ({commit})
 
 Backup tag: vp-backup-{timestamp}
 
 To undo this rollback:
   git reset --hard vp-backup-{timestamp}
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Adapter Compatibility

AskUserQuestion Tool (ENH-075)

Checkpoint selection uses AskUserQuestion on Claude Code (terminal).

Adapter	Interactive Prompts	Notes
Claude Code (terminal)	✅ AskUserQuestion — REQUIRED at checkpoint selection	Preload schema via ToolSearch first
Cursor / Codex / Copilot / Antigravity	❌ Text fallback	Plain numbered list; re-run with --limit N for more entries

Claude Code (terminal) — AUQ preload required (ENH-059): Before the checkpoint selection prompt, call ToolSearch with query: "select:AskUserQuestion" to load the deferred tool schema. If ToolSearch fails, fall back to plain-text numbered list.

Prompts using AskUserQuestion in this skill:

• Checkpoint selection (Step 1 — tag list + "Show N more →" pagination + "Enter manually")

<success_criteria>

• Checkpoints listed with dates
• AUQ checkpoint picker shown on Claude Code terminal (text fallback on other adapters)
• "Show N more →" pagination works; disappears when no more checkpoints
• --limit N controls page size (default: 10)
• --list flag outputs plain-text table and exits (no AUQ)
• Target validated before rollback
• Backup created before changes
• State files updated after rollback
• Undo instructions provided </success_criteria>
