Resume Any Chat

Resume Any Chat

Use this plugin skill for local multi-provider chat history work across the current user's home directory:

• Codex from .codex/sessions
• Claude from .claude/projects plus .claude/history.jsonl
• Antigravity from .gemini/antigravity-cli/brain/*/.system_generated/logs

Workflow

1. Default to listing useful recent sessions directly in-chat.

Show recent Codex, Claude, and Antigravity sessions first unless the user already named a provider/session. The default professional list format is:

• recent 10
• per item show:
• id
• title
• last message
• then show exactly these next actions:
• Continue in Codex
• Continue Native
• Summarise
• Import into Codex History (Experimental)
• if session cwd and current workspace differ, say that briefly and suggest the safer option
• stop there unless the user explicitly picks one of those actions

1. Refresh/export the current index:

node ../../runtime/cli.js export

1. Useful commands:

node ../../runtime/cli.js latest
node ../../runtime/cli.js latest claude --limit 15
node ../../runtime/cli.js session claude 
node ../../runtime/cli.js handoff antigravity 
node ../../runtime/cli.js import-history claude 

Command mapping:

• show all history
• show history
• list history
• show recent
• show me all history

For any of the above, you must run:

node ../../runtime/cli.js latest

If the user names a provider, you must run:

node ../../runtime/cli.js latest 

1. Launch the local 3-tab viewer:

node ../../runtime/cli.js serve

1. Use the built-in flows:

• Native resume:
• codex resume
• claude --resume
• agy --conversation
• Cross-provider continuation:
• create a Codex handoff file
• launch a fresh Codex session from that handoff
• Experimental import:
• only when the user explicitly chooses Import into Codex History (Experimental)
• import a foreign session into Codex history without replacing the safer default flows

Rules

• Do not treat foreign-session import as the default continuation path.
• prefer native resume or Codex handoff first
• use experimental Codex-history import only after explicit user choice
• Do not read Antigravity token-monitor/auth cache unless the user explicitly asks for that risk.
• Prefer transcript_full.jsonl for Antigravity when available.
• If no trustworthy cwd exists, do not auto-launch the foreign CLI.
• show session should include recent turns by default.
• default: show the overview plus last 5-8 meaningful messages
• verbose: include more context, including thinking/tool lines when useful
• If the user says continue here, do not push them into an external resume flow first.
• run handoff without --launch
• use that summary and handoff file to continue inside the current Codex thread
• Never auto-resume, auto-handoff, auto-summarise, or auto-open anything immediately after listing.
• listing is one step
• action happens only after the user explicitly chooses it
• Import into Codex History (Experimental) is opt-in only.
• add it as a selectable action
• do not use it unless the user explicitly chooses it
• Do not answer show all history by describing, linking, or summarizing state.json.
• state.json is an internal cache/export artifact
• mention it only if the user explicitly asks for raw JSON, export files, cache debugging, or file paths
• For show all history and similar list requests, return the direct latest output itself.
• do not replace it with totals-only summaries
• do not ask for provider + session id before showing the actual list
• If the session already has a clear unfinished task, continue that task directly instead of ending with If you want, I can...
• ask only if the next task is ambiguous or risky
• The rule above applies only after the user has already chosen Continue in Codex or equivalent.
• Do not invent a different menu or a generic conversational close.
• follow the list-first flow above
• avoid endings like If you want, I can... when the user already asked to continue
• Avoid rigid command-only replies.
• accept natural requests such as show me more Claude, continue the latest Antigravity here, open viewer, resume this Codex session
