I wrote a skill to closely mirror (though enhances) the /insights tool in Claude Code, but added in ability to review all Codex work and write a single report. It is built in a way that can begin execution from either, but run the other headless to continue working on the report output.
If anyone expresses interest, I will publish to a git repo.
Here's what it does: Each agent reads all my sessions from the last 30 days, writes an HTML report, then auto-invokes the other agent's CLI (codex exec / claude -p) to append a peer-reviewed Second Opinion.
Both agents coach me on how I'm managing them for things like delegation quality, checkpoint discipline, escalation thresholds, and things I can do to improve my agentic coding.
As a funny example, the skill told me 43% of my Claude spend this month went to sessions where I kept giving Claude "one more chance" instead of handing off to Codex. Lolz. π€·π½ββοΈπ€¦π½ββοΈ
The unlock isn't the stats. It's that the skill is framed as coaching for managing agents, not just usage reports. How do I delegate? When do I escalate? Where are my skill-portfolio gaps? It turns out that my biggest habit problem is tolerating Claude loops far too long before reaching for Codex. I have the escalation tool, but I don't reach for it often or fast enough.
