Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Latest Message

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

Instructions

  1. Parse the user's input after /cmd-latest-msg.
  1. 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 — read latest from claude|codex|gemini /cmd-latest-msg help — show this usage ``

  1. 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:

``bash mkdir -p /tmp/agents/ ``

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

e. Confirm with:

`` Stored to: /tmp/agents//latest.md /tmp/agents//.md ``

  1. 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//latest.md.

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

  1. use — display another agent's latest message:

a. Validate ` is one of: claude, codex, gemini`.

b. Read and display /tmp/agents//latest.md.

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