Rosetta

Q: What is a Claude Code skill and how does the Rosetta skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Rosetta is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the General category.

Reconcile ALL prior agent conversations (Claude Code, Codex, Droid/Factory, Hermes, Cursor) with git history and docs into a cited ground truth, and distill durable decision records (ADRs/PDRs/BDRs). Use whenever the user wants to catch up on or get the state of a project, build or refresh a ground truth, read or mine previous agent/AI conversations, recover or record what was decided (technical, product, or business), capture/index/validate ADRs or PDRs, discover which projects on the machine have agent history, or onboard onto unfamiliar work — even if they don't say the word "Rosetta".

About this skill (catalog notes)

How Rosetta fits the catalog

Rosetta sits in the General category under the general-misc sub-topic in the ClaudSkills catalog. There are 10 related skills indexed alongside it; comparing a few before installing usually reveals which fits your workflow best.

These notes are auto-generated from features detected in the SKILL.md file and from this catalog's structure — they aren't part of the source repository.

From the source SKILL.md

The same project lives under five incompatible transcript-storage schemes (Claude Code, Codex, Factory/Droid, Hermes, Cursor), two of which aren't project-scoped at all, several of which have drifted across CLI versions. Reading "all our previous agent conversations" by hand is impossible and reading them into one context is ruinous. Rosetta decodes them all — like the Rosetta Stone recovering one meaning across many scripts — and reconciles them with the code, git history, and docs into a single cited ground-truth document.

What this skill does

Rosetta is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/rosetta/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever the user wants to catch up on or get the state of a project, build or refresh a ground truth, read or mine previous agent/AI conversations, recover or record what was decided (technical, product, or business), capture/index/validate ADRs or PDRs, discover which projects on the machine have agent history, or onboard onto unfamiliar work — even if they don't say the word "Rosetta".

Who uses this skill

The Rosetta Claude Code skill is built for Claude Code users and developers across all disciplines looking for general-purpose AI assistance. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 119,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
