Skill Creator

What it does
Skill Creator is an agent skill from PersonalJarvis/PersonalJarvis. Creates a new Jarvis skill from the user's description — the assistant writes the whole skill (name, trigger phrase, schedule, steps, spoken answer format) and files it as a draft. Use when the user wants to build a new skill, routine or automation ("erstell mir einen Skill, der …" / "create a skill that …" / "mach aus diesem Workflow einen Skill").
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts, reference files and assets (for example `agents/README.md`, `assets/README.md` and `references/anthropic-skill-creator.md`).
It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: Your AI assistant, built for the agentic era. Open source and local: talk to it, and it runs your agents, your coding CLIs, your browser and your apps. Windows, macOS, Linux. The licence is Apache-2.0.

What it can do on your machine
Read from SKILL.md and the folder at commit 46acfbd. 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 1 file in scripts/, which the agent can run.
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 Creator loads about 1.3k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 91 tokens; SKILL.md has 343 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.
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); the scripts in this folder are not scanned.

Skill Creator
The user wants a NEW skill. Write it for them — do not interview them.
Steps
- Restate everything the user asked for as one complete description: what the skill does, in which order, at what time or on which spoken phrase it should fire, which services it touches (mail, calendar, tickets, music, smart home, …), and every preference or example they gave (counts, genres, "always something new"). Services named inside the request are the skill's content — never act on them now (do not play the song, do not read the mail).
- Call the
create-skilltool ONCE with that description asintent, the name the user gave (or an empty string), the spoken trigger phrase if they named one, and the schedule as a 5-field cron when they named a time ("jeden Morgen um 6" →0 6 * * *). The assistant writes the whole skill itself — steps per connected tool, trigger, spoken answer format — and files it as a draft. - If the result says no model could write it, say so plainly and offer to try again in a moment. Do not fall back to a worker and do not paste the request into a file yourself.
- The new skill is a draft. Only when the user explicitly asked for it to be
switched on right away ("und aktiviere ihn gleich"), call
skill-enablewith the name the result returned — never enable unasked. Switching a skill off, on, or deleting one isskill-disable/skill-enable/skill-delete; the list isskills-list. - If the user asks to change an EXISTING skill's content, tell them that editing lives in the Skills view (this card only creates); name the skill they mean.
Answer format
One or two spoken sentences in the user's language: the skill's name, what it does and when it fires, and that it is waiting as a draft in the Skills view until they switch it on. Never read the generated instructions aloud.
