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 | $0.00041 | $0.01048 |
| Opus 5 | $0.00020 | $0.00524 |
| Sonnet 5 | $0.00008 | $0.00210 |
| Haiku 4.5 | $0.00004 | $0.00105 |
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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Creator
A skill for creating new skills and iteratively improving them.
Quick Start
- Define skill requirements — Discuss with the user what the skill should do
- Write SKILL.md — Follow the template below
- Install the skill — Copy directly to
~/.chatspeed/skills/ - Test and iterate — Test and optimize in conversations
Creating a Skill
1. Understand User Requirements
Start by understanding the user's intent:
- What should this skill enable the AI to do?
- When to trigger? (When does the user invoke this skill)
- What is the expected output format?
- Should test cases be created?
Ask proactively about edge cases, input/output formats, example files, and success criteria.
2. Write SKILL.md
Fill in according to requirements:
---
name: skill-name
description: Skill description (trigger condition + functionality)
---
# Skill Name
## Function Description
(Detailed explanation)
name: Skill identifier, English + hyphens
description: Trigger condition + functionality. This is the main triggering mechanism — explain what the skill does and when to use it. All "when to trigger" information goes here, not in the body.
Tip: Make descriptions slightly "proactive". For example, don't just write "how to build a dashboard", write "how to build a dashboard. Use this skill when the user mentions dashboards, data visualization, internal metrics, or wants to display any type of data."
3. Skill Directory Structure
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter (name, description required)
│ └── Markdown explanation
└── Resource files (optional)
├── scripts/ - Helper scripts
├── references/ - Reference documents
└── assets/ - Asset files
4. Install the Skill
Copy the skill folder directly to ~/.chatspeed/skills/:
cp -r skill-name/ ~/.chatspeed/skills/
ChatSpeed will automatically load skills from this directory.
Testing and Optimization
What ships with it
3 files 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 aidyou/chatspeed (21 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 1,048 once invoked, about $0.0002 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.

forensic-transcript-translator
法證級美股電話會議逐字稿翻譯工具，含獨立交叉審計。五階段流程：結構指紋提取 → 動態術語鎖定 → 嚴格逐字翻譯 → 獨立 subagent 法證審計 → 組裝輸出。確保 100% 零遺漏、零曲解。使用時機：(1) 使用者提供英文 earnings call 逐字稿檔案並要求翻譯成繁體中文, (2) 使用者要求「法證翻譯」或「forensic translate」, (3) 使用者要求翻譯長篇（超過 2000 字）財報電話會議逐字稿且強調不可遺漏。與 taiwan-earnings-translator 的差異：本技能增加「結構指紋比對」與「獨立 subagent 交叉審計」，適用於對完整性有嚴格要求的場景。.
