Cmd Latest Msg

Latest Message

Persist the last agent message to disk for cross-agent visibility.

Instructions

1. Parse the user's input after /cmd-latest-msg.

2. help (or no argument) — print usage and stop:

   Usage:
     /cmd-latest-msg save             — save your last message
     /cmd-latest-msg use              — read latest from the current agent
     /cmd-latest-msg use <agent>      — read latest from claude|codex|gemini
     /cmd-latest-msg help             — show this usage
   

3. save — save the last assistant message:

   a. Determine which agent you are from runtime context:

   • Claude Code → claude
   • Codex CLI → codex
   • Gemini CLI → gemini
   • If inference fails, default to codex

   b. Create the output directory:

   mkdir -p /tmp/agents/<agent>
   

   c. Capture your last assistant message — the response you gave immediately before the user invoked this skill.

   d. Write it to two files using the Write tool:

   • /tmp/agents/<agent>/latest.md — always overwrite
   • /tmp/agents/<agent>/<unix_timestamp>.md — timestamped copy (use date +%s to get the timestamp)

   e. Confirm with:

   Stored to:
     /tmp/agents/<agent>/latest.md
     /tmp/agents/<agent>/<timestamp>.md
   

4. use — display the latest message for the current agent:

   a. Infer the current agent using the same runtime-context rules as save.

   b. Read and display /tmp/agents/<agent>/latest.md.

   c. If the file doesn't exist, say: No messages found for <agent>.

5. use <agent> — display another agent's latest message:

   a. Validate <agent> is one of: claude, codex, gemini.

   b. Read and display /tmp/agents/<agent>/latest.md.

   c. If the file doesn't exist, say: No messages found for <agent>.
