Accelerate AI-assisted development with a skills catalog for agentic CLIs: enforce Python/uv conventions, generate PRs from diff context, resolve merge conflicts, scaffold cross-tool agent skills, create structured GitHub issues, render Mermaid diagrams, audit code for production readiness, and capture session learnings into AGENTS.md.
npx claudepluginhub olshansk/agent-skills --plugin agent-skillsPrime the agent with a behavioral persona for the conversation
Catch the user up on what the agent has been doing in the current session with 3-5 ultra-tight bullet points. Use when the user invokes /cmd-what, asks "what are you doing", "what did you do", "catch me up", "status", "where are we", or otherwise needs a fast situational summary of in-flight agent work.
Get a second opinion on the current plan from Codex (codex exec headless mode) before leaving plan mode. Pipes the plan to codex, captures critique and gap analysis, then proposes a revised plan with an explicit changelog of what changed and what was rejected. Triggers on "/cmd-codex-review-plan", "review plan with codex", "ask codex about this plan", or before approving auto mode on an exit-plan prompt.
Get a second opinion on what Claude just implemented from Codex (codex exec headless mode). Pipes Claude's summary plus the working-tree diff to codex, asks codex to leverage cmd-pr-follow-up and cmd-pr-edgecase methodology to surface bugs, test gaps, edge cases, and simplification opportunities, then synthesizes a prioritized iteration plan from the feedback. Triggers on "/cmd-codex-review-unstaged", "review my changes with codex", "have codex review what I just did", or after a non-trivial implementation pass before commit.

[!TIP] Start with
cmd-session-commit— it turns every coding session into durable knowledge by extracting patterns, decisions, and gotchas into yourAGENTS.md. Future sessions (and future agents) pick up right where you left off.
