通用音频处理：音频剪辑/裁剪、格式转码（mp3/wav/m4a/aac）、音量归一化、从视频提取音轨、多段拼接、淡入淡出、变速（保音高）。当用户说“剪音频”“裁一段”“转成 mp3”“调音量/响度”“提取音轨/扒音频”“拼接音频”“淡入淡出”“加速/减速音频”“变速不变调”时使用。与 audio-denoise 的区别：audio-denoise 专做降噪，audio-editing 做除降噪外的通用音频操作（也内置 denoise 作为兜底）。

Each tab says whether it installs commit 5a597e5, the one we checked, or the latest version.

No tab for your agent? Use Any agent for OpenCode, Goose, Windsurf (Devin Desktop), Zed, Roo Code, Factory Droid, Junie, Amp and Antigravity, and Claude Code for Cline. Kiro needs the folder copied by hand.

Skills in the Claude apps belong to your account rather than to a project.

Make audio-editing.zip, with the skill folder at the top level:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/ZJU-REAL/Easel.git "$tmp" &&
  git -C "$tmp" fetch -q --depth 1 origin 5a597e5f3ef5b01098b53f36caf719dd9a32b7bf &&

  git -C "$tmp" checkout -q 5a597e5f3ef5b01098b53f36caf719dd9a32b7bf &&
  out="$(mktemp -d)" &&
  cp -R "$tmp"/skills/builtin/audio-editing "$out"/audio-editing &&
  (cd "$out" && zip -qr - audio-editing) > audio-editing.zip &&
  rm -rf "$tmp" "$out"

In Claude, open Customize > Skills, select +, then + Create skill > Upload a skill, and choose audio-editing.zip.

On Free, Pro and Max plans, turn on Code execution and file creation (Create and edit files in newer settings) under Settings > Capabilities.

In a running Copilot CLI session, run /skills reload.

Or install it with gh skill, which also installs the commit we checked. Needs GitHub CLI 2.90 or later.

Gemini CLI docs

Pinned to commit 5a597e5, the one we checked.

Codex, Cursor, Copilot, VS Code, Gemini CLI, OpenCode, Goose, Amp and Zed all read .agents/skills; Claude Code and Kiro list only their own folders.

From your project's root folder:

tmp="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/ZJU-REAL/Easel.git "$tmp" &&

  mkdir .agents/skills/audio-editing &&
  cp -R "$tmp"/skills/builtin/audio-editing/. .agents/skills/audio-editing/ &&
  rm -rf "$tmp"

Or use the skills CLI from skills.sh. Installs the latest version, not the one we checked. The skills CLI reports installs to skills.sh unless you set DISABLE_TELEMETRY=1.

Agent Skills docs

What it can touch

From the files and frontmatter at commit 5a597e5. This is how much a skill can do, not whether it is risky.

What it can touch: Scripts or outside hosts

Runs shell commands
Its instructions or files give the agent commands to run on your computer.
Names web addresses
It mentions outside web addresses the agent may visit. We list them but don't follow them.

Pattern check

Pattern check: nothing flagged · commit 5a597e5 · 27 Oct 2026

We checked every text file in this skill, at commit 5a597e5 on 27 Oct 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.

Format check

Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.

Agent Skills specPasses with warnings
The open format from agentskills.io, held to what the strictest agents enforce, so one folder loads everywhere.
- Warning
  Fields outside the spec: layer. Uploads to the Claude apps and API, and the spec's validator, reject the file; most agents ignore these fields. O1
  Fix: Delete them for a portable skill, or keep them if you only target the agents that read them.
- Note
  The description doesn't say when to use the skill. D6
  Fix: Add a sentence such as "Use when …" naming the requests or files that should trigger it.
- Note
  There is no license field, so readers can't tell whether they may reuse the skill. O2
  Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
- Note
  Reference files that SKILL.md doesn't link: EASEL-META.md. Anthropic suggests linking every reference file directly from SKILL.md. B4
  Fix: Link each one from SKILL.md and say when to read it.
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
  Claude Code ignores fields it doesn't know: layer. O1
  Fix: Check the spelling against Claude Code's field list, or delete them.
- Note
  Reference files that SKILL.md doesn't link: EASEL-META.md. Anthropic suggests linking every reference file directly from SKILL.md. B4
  Fix: Link each one from SKILL.md and say when to read it.
Claude apps & API uploadFails
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Error
  Upload and packaging fail on fields outside the spec: layer. O1
  Fix: Delete them, and keep your own data under metadata as text values.
- Note
  The description is 225 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
  Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
  Reference files that SKILL.md doesn't link: EASEL-META.md. Anthropic suggests linking every reference file directly from SKILL.md. B4
  Fix: Link each one from SKILL.md and say when to read it.
OpenAI (Codex & API)Passes with warnings
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Warning
  Fields outside the spec: layer. Codex ignores them; OpenAI doesn't say whether its upload accepts them. O1
  Fix: Delete them, or move your own data under metadata as text values.
VS Code & CopilotPasses
VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.
- Note
  VS Code ignores fields it doesn't support: layer. O1
  Fix: Delete them unless another agent you target reads them.
