Software development skills for Claude Code, Codex CLI, and Agent Plugins clients: deep planning, root-cause analysis, rigorous PR review, spec-aware rebasing, agent-oriented repo docs
README
A plugin of skills that covers the full development cycle: spec, plan, build, submit, review, test. Nine are shipped, one is planned. It runs on Claude Code, Codex CLI, and any Agent Plugins client.
| Skill | What it does | When it triggers |
| --- | --- | --- |
| /spec | Turns a fuzzy feature request into a reviewable product spec — goals, non-goals, testable acceptance criteria with stable IDs, invariants — that later skills cite by path and ID. | "/spec", "spec this out", "write a product spec", "turn this idea into requirements". |
| /blueprint | Validation-first planning: tests every load-bearing assumption against reality, cross-checks specs, architecture, and conventions, then delivers a plan a human can accept or reject from its first two sections. | "/blueprint", "blueprint this", "plan this thoroughly", "deep plan" — non-trivial changes where a wrong direction would burn meaningful time. |
| /rca | Root-cause analysis: repro, timeline, evidence-backed 5-whys chain, sibling sweep, then two fix proposals (symptom vs cause) plus prevention for the whole class. | "/rca", "root cause", "5 whys", "why is this failing" — failures you want to learn from, not just patch. |
| /repo-docs | Bootstraps or extends AGENTS.md + docs/ so coding agents find the project's real conventions instead of guessing. | "document the project for coding agents", "set up agent docs", "add AGENTS.md". |
| /rebase | Spec-aware rebasing: replays commits onto a new base while keeping the original intent, invariants, and conventions intact — not just resolving conflicts. | "rebase this branch on X", "move these commits onto the new base". |
| /submit | Ships
