Copy the whole folder (SKILL.md and every file beside it), keep the folder name "hooks", then confirm the skill loads.Claude Code copies the folder itself, the same result as the manual copy. Check what it changed before you commit it.

hooksHooks is a skill in parcadei/Continuous-Claude-v3 (3.9k stars). Its SKILL.md is about 344 tokens, and copies of it appear in 2 other owners' repositories. Licence: MIT.
Read from SKILL.md and the folder at commit d07ff4b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
npxFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Hooks loads about 344 tokens when it runs. Until then it costs about 7 tokens; SKILL.md has 62 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Categories
Run `npx skills add parcadei/Continuous-Claude-v3 --skill hooks -a claude-code`. Or copy the skill folder (.claude/skills/hooks in parcadei/Continuous-Claude-v3) into .claude/skills/hooks in your project. Claude Code loads it when a task matches its description.
Run `npx skills add parcadei/Continuous-Claude-v3 --skill hooks -a codex`. Or copy the skill folder (.claude/skills/hooks in parcadei/Continuous-Claude-v3) into .agents/skills/hooks in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add parcadei/Continuous-Claude-v3 --skill hooks -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/hooks, .gemini/skills/hooks, .github/skills/hooks and .opencode/skills/hooks in your project.
Going by SKILL.md and its folder, Hooks needs the command-line tools its instructions call (npx).
SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Hooks is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 344 tokens (SKILL.md is roughly 1.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
