Skill Installer

What it does

When your agent uses it

• Tasks that involve Skill management

Example prompts

• “/skill-installer”

Requirements

• Python 3

Workflow steps

11 steps, taken from the first numbered list in SKILL.md.

1. 1Resolver fonte - identifica o diretorio da skill
2. 2Validar - roda 10 checks no SKILL.md e estrutura
3. 3Determinar nome - extrai do frontmatter ou usa --name, compara versoes
4. 4Verificar conflitos - checa se ja existe no destino
5. 5Backup - se sobrescrevendo, faz backup timestamped (exclui backups/ e staging/)
6. 6Copiar via staging - copia para area temp, valida hash, depois move
7. 7Registrar no Claude Code CLI - copia SKILL.md para .claude/skills//
8. 8Atualizar registry - roda scan_registry.py --force (com deduplicacao por nome)
9. 9Verificar instalacao - confirma arquivos, registry, registro (5 checks)
10. 10Empacotar ZIP - cria ZIP para upload no Claude.ai web/desktop (validado)
11. 11Logar operacao - append em install_log.json (com rotacao automatica)

What it can do on your machine

Read from SKILL.md and the folder at commit 1e53ce2. It shows what the files ask for, not the result of running them.

• Tool permissions

  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.

• Runs code

  Ships 5 files in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • python

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Skill Installer loads about 2.8k tokens when it runs, and up to ~3.1k if it reads all its reference files. Until then it costs about 42 tokens; SKILL.md has 978 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~42

When it runs · the whole SKILL.md, loaded when a task matches

~2.8k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~3.1k

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.

Safety

• NoteMentions a .env fileSKILL.md:264

  idos**: bloqueia instalacao se encontrar .env, *.key, *.pem, credentials.*

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); the scripts in this folder are not scanned.
