Generate a structured handoff document + ready-to-paste starting prompt for the next session, preserving context across session boundaries. **Use `/handoff` whenever you reach context limits, need to hand off to a colleague, or want to continue in a fresh session.** Modes: `/handoff` (manual mode, output prompt), `/handoff auto` (auto-launch next session). Includes state summary, acceptance criteria, references — no manual reconstruction needed.
Mercury's preset Main → Dev → Acceptance chain for executing a single, well-scoped coding task end-to-end with blind acceptance review. **Use this skill proactively** whenever the user has a ready-to-implement task (instead of coding inline) — even if they don't explicitly ask for 'dev pipeline'. Say 'dev pipeline', 'dispatch task', '派发任务', 'blind review', or '完整开发链'. When the task is well-scoped, the skill spawns dev subagent to implement, acceptance subagent to blind-review, then loops or completes based on verdict. Independent of Mercury's other modules — works in any repo with .claude/agents/dev.md + .claude/agents/acceptance.md.
Autonomous iterative research with mechanical quality gates — multi-round loops, per-round verification, agent doesn't self-decide completion (gate does). **Use this proactively for ≥3 research questions or multi-source verification** — even if the user just says 'research X'. For quick lookups (1–2 questions, single source), use web-research instead. Triggers: 'autoresearch', '自动研究', '深度调研', 'deep research', '多轮调研', 'comprehensive research'. Works standalone or under Mercury dispatch.
Mercury's pixel-frame animation pipeline — generate a sprite frame sequence (e.g. 4-frame walking cycle, idle pose set, attack arc) from a character bible JSON + scenes JSON, with built-in verify rubric (frame count, dimension uniformity, palette quantization, dHash consistency, optional loop closure) and structured retry loop. **Use proactively whenever the user asks to generate any frame sequence, sprite sheet, walking cycle, or animated pixel asset** — even if they don't say "animate-frames" explicitly. Triggers: 'animate frames', 'sprite sheet', 'sprite frames', 'walking cycle', 'frame sequence', 'pixel animation', '生成精灵帧', '动画帧序列', '像素动画', '精灵表'. Wraps `scripts.image_gen` (Slice B) which in turn invokes the `adapters/gpt-image-2/` adapter (Slice A, MIT mount of `wuyoscar/gpt_image_2_skill` via uvx-pinned-SHA). Phase 2 Slice C of Mercury Issue #351.
Run Claude Code deep-review and Codex code-audit in parallel, then consolidate findings. **This is the mandatory pre-commit review step per Mercury CLAUDE.md** — use this instead of /code-review or /auto-verify. Trigger: 'dual verify', 'dual-verify', 'parallel review', 'run dual verify', '双路验证', '并行review', '代码审查', 'review before commit'. Use before any PR creation or direct commit to protected branches.
Task management for Mercury's own self-development via GitHub Project #3 — pulls next Phase + P0 Todo task, marks In Progress, links work products (PR/Issue), moves to Done. **Use this for Mercury work** — even for housekeeping tasks. Triggers: 'next task', '下一个任务', '拉任务', '认领任务', 'project status', '更新 project', 'Mercury 项目', 'Phase X'. DO NOT use for external projects (Phase 3 will replace this with Memory Layer + Dev Pipeline). BOOTSTRAP-ONLY: retires when Phase 3 ships.
Run AgentKB knowledge base health checks (lint) — detects broken links, orphan pages, stale articles, contradictions. **Run this regularly to keep KB healthy, especially before major refactors or content merges.** Requires `$AGENTKB_DIR` env var. Triggers: 'lint KB', 'KB health check', '知识库检查', 'check KB', 'KB lint', 'knowledge base health'. Offers `/kb-lint structural` (fast) or `/kb-lint full` (with LLM contradiction detection).
Automate the full PR lifecycle with Argus review bot: create PR, poll for review, read findings, fix issues, push and wait for Argus incremental review, merge after approval. **Always use this skill when code is ready to PR** — even if the user only says 'push' or 'merge' — to avoid manual Argus polling. Trigger: 'PR', 'pull request', 'create PR', 'merge PR', '提PR', '合并', 'PR流程', 'check PR status'. Use after dev work reaches `implementation_done` and branch is pushed. Replaces manual C4-C7 steps in Mercury workflow.
