What it does

Skill Creator is an agent skill from DemonDamon/AgenticX. Create or update AgenticX skills from a live conversation workflow. Use when the user asks to save, persist, or encapsulate a multi-step procedure as a local skill, when tool calls were repeated too often, or when refining SKILL.md frontmatter and discoverability after skillmanage.

Its SKILL.md is about 880 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Agent Workflows, covering Skill authoring. The repository describes itself as: AgenticX is a unified, production-ready multi-agent platform — Python SDK + CLI (agx) + Studio server + Machi desktop app. Features Meta-Agent orchestration, 15+ LLM providers… The licence is Apache-2.0.

When your agent uses it

The user asks to save
Encapsulate a multi-step procedure as a local skill
Tool calls were repeated too often
Refining SKILL.md frontmatter and discoverability after skillmanage

Example prompts

“/skill-creator”

Workflow steps

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

Goal — what the skill enables the agent to do
Trigger — phrases/contexts when the skill should activate (put in description, not only the body)
Inputs/outputs — formats, files, APIs, edge cases the user corrected
Proven steps — the sequence that actually worked (not aspirational steps)

What it can do on your machine

Read from SKILL.md and the folder at commit c1af2c7. 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 (its code samples are yaml and markdown).
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 882 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 312 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~74
When it runs · the whole SKILL.md, loaded when a task matches: ~882

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

The full file from DemonDamon/AgenticX at commit c1af2c7, republished under its Apache-2.0 licence (© DemonDamon). 312 words, ~882 tokens.

Download SKILL.mdSave it as .claude/skills/skill-creator/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.

Skill Creator (AgenticX)

Guide for turning a successful conversation workflow into a discoverable skill under ~/.agenticx/skills/.

For listing, installing, or registry operations, use the separate agenticx-skill-manager skill.

When to use

User says: 「落盘 skill」「封装成 skill」「工具调用太多，保存成 skill」
You completed a non-trivial task (roughly 5+ tool calls) and the steps should be reused
An existing agent-created skill needs a clearer description or body after skill_manage patch

Capture intent (from current chat)

Before writing anything, extract from this conversation:

Goal — what the skill enables the agent to do
Trigger — phrases/contexts when the skill should activate (put in description, not only the body)
Inputs/outputs — formats, files, APIs, edge cases the user corrected
Proven steps — the sequence that actually worked (not aspirational steps)

Confirm the skill name (hyphen-case, e.g. a-stock-daily-report) with the user if unclear.

SKILL.md anatomy

my-skill/
├── SKILL.md          # required
├── scripts/          # optional — deterministic helpers
└── references/       # optional — long docs loaded on demand

Frontmatter (required)

yaml

---
name: my-skill          # MUST match skill_manage name= parameter
description: One line on what it does AND when to trigger it (pushy but accurate).
---

name — lowercase hyphen-case identifier; required for Desktop Skills scan
description — primary trigger signal; include when-to-use phrases
Optional: version, title, requires_tools, metadata — AgenticX allows these; do not omit name

Keep the body under ~500 lines; split heavy detail into references/.

Persist (mandatory path)

skill_use(skill-creator) — you are here; follow this guide
Draft full SKILL.md text (frontmatter + body)
skill_manage(action='create', name='<dir-name>', content='<full SKILL.md>')
- Or from_path / from_url for large files
- Never bash_exec / file_write directly into ~/.agenticx/skills/
Read the tool result:
- discoverable: true → skill appears in Settings → Skills
- frontmatter_fixed non-empty → tell the user what was auto-corrected (e.g. injected name)
- ERROR → do not claim success; fix and retry
skill_list — optional double-check the name appears

Writing quality

Imperative steps; concrete commands and paths
Include failure modes you hit in this session (proxy issues, missing deps, etc.)
No conversation transcript dumps — actionable procedure only
Security: no exfiltration, no misleading or destructive instructions
