What it does

Skill Installer is an agent skill from holaboss-ai/holaOS. Install workspace skills from curated sources or import open-source skills from GitHub.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Skill management. It works with GitHub. The repository describes itself as: Open-source agentic workspace enterprises can make their own. Connect the systems you already run — 100+ integrations, MCP, chat tools, apps, browser, local files — with shared…

When your agent uses it

  • Tasks that involve Skill management

Example prompts

  • “/skill-installer”

Workflow steps

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

  1. Install each workspace skill under skills// with its SKILL.md plus any helper files. For skills you author by hand, create these files…
  2. Guidance only: do not install workspace skills into runtime/harnesses/src/embedded-skills/. Do not install into $CODEX_HOME/skills unless…

What it can do on your machine

Read from SKILL.md and the folder at commit 4684714. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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 639 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 338 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~639

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

Auto-check passed

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 338 words (~639 tokens).

“Use this skill to install workspace skills into the workspace-local skills/ directory.”
