Working Session Retro skill for Claude and Codex

Working Session Retro as an AI skill. It asks for Session description, Session log or notes, Tools and setup and 2 more, then does the rest. Free to install…

Install it once and Claude or Codex runs it for you. When your request matches, your AI loads the skill, asks for anything it is missing, and works through the template itself. Prefer to fill it in by hand? See the full prompt template.

When it is used

Use when a working session just ended and the friction in it should be turned into concrete setup or process fixes. Do not use for reviewing the code produced or reporting project status. Related topics: productivity, AI.

What it will ask you for

• Session description (longer free text)
• Session log or notes (longer free text)
• Tools and setup (longer free text)
• Biggest annoyance (free text, e.g. "What felt worst")
• Scope (choose one: This session only, Recurring patterns, Both)

How it works

1. Walk the session and mark each moment that wasted time, with the cause.
2. Estimate the cost of each moment and how likely it is to recur.
3. Group causes into environment fixes and request-style fixes.
4. Rank fixes by cost times recurrence, most severe first.
5. Give a concrete small change for each top item and note what went well.

What you get

A ranked list of friction points with cause, cost and a concrete fix each, followed by a short list of what to keep doing.

What it watches out for

• Listing every small annoyance with equal weight, which hides the three that matter.
• Proposing a large tooling project when a one-line config change would remove the problem.
• Blaming the person instead of the missing context or setup.
