Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00062 | $0.00874 |
| Opus 5 | $0.00031 | $0.00437 |
| Sonnet 5 | $0.00012 | $0.00175 |
| Haiku 4.5 | $0.00006 | $0.00087 |
Grade A, and why
skill-creator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on 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
descriptionor body afterskill_managepatch
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.

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

skill-creator is a skill published in the GitHub repository DemonDamon/AgenticX (219 stars, last pushed 4d ago), licensed Apache-2.0. It adds 62 tokens to every session and 874 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
