Is the Last Tag skill free?

Yes. The skill itself is free from umputun/cc-thingz. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Last Tag SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 5/5.

How do I install Last Tag?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Last Tag with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works
Score: 8.8/10
Tested: Jul 21, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 5f4e3de

Built two temp git repos (isolated HOME) with a tag plus commits and ran the skill's commands directly. git describe/git log with the skill's format string produced the documented pipe-delimited rows; I verified both branches: a two-author repo yields the multi-author table with an Author column, a one-author repo collapses to the single-author layout, and the git show --stat detail command works. Baseline (git log --oneline) gave bare hash+subject with no date/author/tag header; the skill produces an aligned markdown table plus an interactive drill-down step — a concrete, observed improvement. No external scripts referenced, no security smells.

What Last Tag does

Runs git to find the most recent tag and lists every commit since it as a formatted markdown table, switching between single-author and multi-author column layouts automatically. Triggers when the user asks what changed since the last release, wants commits since the last tag, or asks what is new / unreleased. After the table it offers an interactive prompt to show full git show --stat details for all or a specific commit.

How to install Last Tag

git clone --depth 1 https://github.com/umputun/cc-thingz.git /tmp/last-tag-src
mkdir -p ~/.claude/skills
cp -R /tmp/last-tag-src/plugins/release-tools/skills/last-tag ~/.claude/skills/last-tag
# Self-contained: no external scripts, no deps beyond git. Uses Bash + AskUserQuestion.
# Plugin-marketplace alternative: /plugin marketplace add umputun/cc-thingz ; /plugin install release-tools
# Must be run inside a git repo that has at least one tag.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.
