Each tab says whether it installs commit 25278e7, 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.

Gemini CLI docs

Pinned to commit 25278e7, 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="$(mktemp -d)" &&
  git clone -q --depth 1 --filter=blob:none --no-checkout https://github.com/affaan-m/ECC.git "$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 25278e7. This is how much a skill can do, not whether it is risky.

What it can touch: Instructions only

It is instructions only: no scripts, no named hosts and no pre-approved tools.

Pattern check

Pattern check: nothing flagged · commit 25278e7 · 26 Oct 2026

We checked every text file in this skill, at commit 25278e7 on 26 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.

How the check works Report an incorrect finding

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
  Paths that may not work once the skill is installed: line 12: ../../ECC-Tools (outside the skill folder). B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- 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.
Claude CodePasses with warnings
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Warning
  Paths that may not work once the skill is installed: line 12: ../../ECC-Tools (outside the skill folder). B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
Claude apps & API uploadPasses with warnings
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.
- Warning
  Paths that may not work once the skill is installed: line 12: ../../ECC-Tools (outside the skill folder). B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
- Note
  The description is 203 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.
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
  Paths that may not work once the skill is installed: line 12: ../../ECC-Tools (outside the skill folder). B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
VS Code & CopilotPasses with warnings
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.
- Warning
  Paths that may not work once the skill is installed: line 12: ../../ECC-Tools (outside the skill folder). B6
  Fix: Use forward-slash paths relative to SKILL.md, and copy shared files into the skill.
