session-handover

Install a PreCompact hook that auto-generates .agent/local/HANDOVER.md before context compaction, plus a SessionStart hook that restores context from a previous handover. Run once to install, then it works automatically forever. Use when the user says "handover", "setup handover", "install handover hook", or wants seamless context transfer between sessions.

Session Handover

Install PreCompact + SessionStart hooks into the project so session handover happens automatically. Run this skill once -- after that, the hooks fire on their own.

Installation Workflow

When this skill is triggered:

  1. Ensure .claude/ directory exists -- create if missing
  2. Read or create .claude/settings.local.json
  3. Merge the hook config below into the existing hooks object (preserve any existing hooks)
  4. Ensure .agent/local/ is gitignored:
    • Check .gitignore for .agent/local/
    • If missing, append:
      # AI agent local files (ephemeral, not for version control)
      .agent/local/
      
  5. Confirm to the user that hooks are installed

Hook Config to Install

Merge this into .claude/settings.local.json:

{
  "hooks": {
    "PreCompact": [
      {
        "matcher": "auto",
        "hooks": [
          {
            "type": "agent",
            "prompt": "Before context compaction, generate a session handover. Create .agent/local/ if it doesn't exist. Write .agent/local/HANDOVER.md with: timestamp, current git branch, then these sections (omit if empty): What Was Done, In Progress, Decisions Made, Abandoned Approaches, Bugs & Fixes, Lessons Learned, Open Questions, Next Steps (as checkboxes), Key Files (as table). Use bullet points only. Be concise. If .agent/local/HANDOVER.md already exists, overwrite it.",
            "timeout": 120
          }
        ]
      }
    ],
    "SessionStart": [
      {
        "matcher": "startup|resume",
        "hooks": [
          {
            "type": "agent",
            "prompt": "Check if .agent/local/HANDOVER.md exists. If it does, read it and briefly summarize the previous session state: key decisions, in-progress work, and next steps. If it does not exist, do nothing.",
            "timeout": 30
          }
        ]
      }
    ]
  }
}

Merge Rules

  • If .claude/settings.local.json doesn't exist, create it with the config above
  • If it exists but has no hooks key, add the hooks key
  • If it has hooks but no PreCompact/SessionStart, add them
  • If PreCompact or SessionStart already have entries, append the new hook entries to the existing arrays (don't replace)
  • Preserve all other settings in the file

How It Works After Installation

  1. Context fills up → Claude Code fires PreCompact → agent writes .agent/local/HANDOVER.md
  2. Compaction proceeds normally
  3. Next session starts → SessionStart hook reads the handover → context restored

No manual action needed. Fully automatic.

HANDOVER.md Structure

The generated handover follows this format:

# Session Handover

Generated: {timestamp}
Branch: {current branch name}

## What Was Done
- {Completed work items}

## In Progress
- {Partially completed work -- what's done, what remains}

## Decisions Made
- {Design decisions with reasoning}

## Abandoned Approaches
- {Approaches rejected and why}

## Bugs & Fixes
- {Bugs encountered and resolutions}

## Lessons Learned
- {Gotchas, quirks, workarounds}

## Open Questions
- {Unresolved decisions needing user input}

## Next Steps
- [ ] {Prioritized, actionable tasks}

## Key Files
| File | Role |
|------|------|
| {path} | {description} |

Manual Trigger

Even after installation, you can manually generate a handover anytime:

  • "generate handover"
  • "wrap up session"

Write to .agent/local/HANDOVER.md using the same template.

Uninstall

Remove the PreCompact and SessionStart entries from .claude/settings.local.json, or delete the file if it only contains these hooks.

Run a multi-model adversarial mutual review with facilitator synthesis: 2+ panelists (different model families where possible — use codex-server / codex-cli for the external-family seat) independently answer, adversarially critique each other across rounds, and the main session acts as facilitator, synthesizing agreements, live disagreements, and calibrated confidence into one answer. Use ONLY on high-stakes, hard-to-reverse claims, designs or decisions, and only when the user EXPLICITLY asks to debate or adversarially review with multiple models — "discuss with Opus and Codex", "red-team this", "devil's advocate", 敵対的レビュー, 相互レビュー, 多モデル討論, 議論させて. A full run costs ~6 subagent/CLI dispatches: state the panel size and round count and get a go-ahead before launching. Where the Workflow tool is available, run the panel as a Workflow (judge-panel / adversarial-verify) instead of ad-hoc fan-out. Do NOT self-trigger on a bare "are you sure?" — that is a cue to OFFER the panel, not to run it.

Orchestrate multiple coding-agent sessions (Claude Code, Codex, Gemini) over the mcp_agent_mail MCP server, observe their progress on a recurring auto-loop, and prevent inconsistencies (file/edit conflicts and contradictory decisions) between concurrent tasks. Auto-manages the agent-mail server, derives the shared room key from the git repo, and runs either as the orchestrator/observer or as a participating worker. Handles the operational details (server startup, room key, reservation conventions) so the user does not have to remember them. Use when coordinating several agent sessions on different tasks at once, watching a swarm of sessions for conflicts, or wiring already-running sessions into a shared coordination room. Trigger phrases: "agent-swarm", "/agent-swarm", "orchestrate agents", "orchestrate multiple claude sessions", "coordinate sessions", "watch for conflicts between agents", "observe the swarm", "prevent inconsistency between sessions", "multi-agent observe", "複数セッションを協調", "エージェント協調", "セッション間の不整合監視", "スウォーム監視", "複数のClaudeを束ねて".

Generate AGENTS.md (cross-tool agent context — Codex CLI, Aider, Cursor, etc.) and wire CLAUDE.md as a symlink so Claude Code reads the same file. Delegates content generation to Claude's built-in /init when needed, then renames + symlinks. Idempotent. Triggers — /agents-init, "generate agents.md", "create agents.md", "share claude and codex context", "set up agents file", "init agents", "agents-init", "cross-tool agent context", "wire claude and agents".

Drive an already-running, LOGGED-IN Chromium browser on macOS via AppleScript — navigate, click, fill forms, scroll, and extract page content from the user's REAL session, with the browser left open and NO profile copy and NO restart. Use when the task needs the existing logged-in session (cookies, auth, current tabs) reused as-is. Trigger phrases: "chrome-use", "ブラウザから取得", "ログイン済みの Chromeで", "ブラウザを操作して", "このページ読んで", "Xのスレッド読んで", "ログインしたまま取得", "自分のセッションでスクレイプ", "read this page in my browser", "scrape with my session", "drive my chrome", "execute JS in my (logged-in) browser", "automate my logged-in browser". Chromium family (Chrome default; Brave/Edge/Arc/Vivaldi via --app). NOT for isolated/throwaway automation where login reuse is unneeded — use playwright-cli for that. macOS only.

codex-cli

無料

Run OpenAI Codex CLI from the terminal for batch / one-shot `codex exec` invocations with output captured to an `-o` file. Use for fire-and-forget runs, scripted CI, code review batches (`codex review`), and resuming a specific session by id (`codex exec resume`). Always use this skill instead of `mcp__codex__codex` and `mcp__codex__codex-reply` MCP tools — CLI is faster and more capable. For streaming UX, multi-turn dialogues that need live state, structured (JSON schema) output, attaching images, or programmatic event handling → **use codex-server instead**. codex-server uses the user's ChatGPT subscription via Codex App Server and decoupled async invocation that bypasses the Bash 2-minute timeout entirely. Trigger patterns (batch-only — chat/streaming triggers belong to codex-server): codex-cli / codex CLI / codex exec / codex review / codex resume / codex fork / batch + {codex, gpt} / one-shot + {codex, gpt} / non-interactive + codex / codex {to a file, -o, output file, captured output} / CI + {codex, gpt} / scripted + {codex, gpt} / fork codex session / resume codex session by id

Run OpenAI Codex via the Codex App Server (JSON-RPC-over-stdio) for streaming multi-turn chat sessions with persistent threads, structured output, image input, and rich event streams. Default entry point for ChatGPT/GPT/Codex-like conversations from the terminal. Uses the user's ChatGPT subscription (Plus / Pro / Team) exclusively via `codex login` — never consumes OPENAI_API_KEY billing, by design. Implementation: TypeScript on deno with npm:@openai/codex-sdk; spawns the existing system codex binary. Decoupled async invocation: every turn returns turn-id in <1 s; the actual SDK work runs in a detached worker that streams to per-turn files under ~/.codex-server/turns/<turn-id>/ — Bash's 2-min timeout never applies. Prefer this over codex-cli for streaming UX, multi-turn dialogues that need live state, structured (JSON schema) output, attaching images, or programmatic event handling. Use codex-cli only for one-shot batch invocations that pre-capture to an -o file. For OpenAI Platform API calls specifically (embeddings, image generation, audio, moderation, batches, files) — not open-ended chat — use openai-cli instead; that path bills OPENAI_API_KEY, this one uses the ChatGPT subscription. Trigger patterns (match any variation): codex / codex-server / codex app server / codex app-server / openai / open ai / OpenAI / chatgpt / chat gpt / ChatGPT / GPT / ask gpt / chat with gpt / gpt session / codex session / streaming chat / multi-turn chat / multi turn chat / second opinion / cross-check / cross check / ai pair programming / another AI / external AI / ask another model / get GPT's take / what does openai think / show me what gpt thinks / structured output from gpt / json schema gpt / resume codex thread / continue codex conversation / continue codex session / /codex-server
