Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 5.1 | $0.00069 | $0.01054 |
| Opus 5 | $0.00034 | $0.00527 |
| Sonnet 5 | $0.00014 | $0.00211 |
| Haiku 4.5 | $0.00007 | $0.00105 |
Grade A, and why
add-new-skills-to-workflow 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 10d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add New Skills to Workflow
Add skills from GitHub to an existing workflow and update all related documentation.
Workflow
Step 1: Download Skills
Use skill-downloader to download skills from GitHub:
python .claude/skills/skill-downloader/scripts/download_from_github.py <repo-url> <skill-path> --output <workflow-path>/.claude/skills/
Parse GitHub URL:
https://github.com/user/repo/blob/main/path/to/skill→ repo:https://github.com/user/repo, skill-path:path/to/skillhttps://github.com/user/repo/tree/main/.claude/skills/my-skill→ repo:https://github.com/user/repo, skill-path:.claude/skills/my-skill
Example:
# For URL: https://github.com/XIYO/zheon/blob/main/.claude/skills/slidev
python .claude/skills/skill-downloader/scripts/download_from_github.py https://github.com/XIYO/zheon .claude/skills/slidev --output ./workflows/talk-to-slidev-workflow/.claude/skills/
# Use --force to overwrite existing
python .claude/skills/skill-downloader/scripts/download_from_github.py <repo> <path> --output <target> --force
Step 2: Read Downloaded Skill
Read the downloaded SKILL.md to understand:
- Skill name and description
- What category it belongs to
- How it fits into the workflow pipeline
Step 3: Update skill-source.json
Add the new skill entry to workflows/<name>/.claude/skill-source.json:
{
"skill-name": {
"source": "https://github.com/user/repo",
"path": "path/to/skill"
}
}
Step 4: Update Documentation
Update these files (all that exist for the workflow):
| File | Updates Required |
|---|---|
workflows/<name>/.claude/skill-source.json |
Add new skill source entry |
workflows/<name>/README.md |
Skill count, skill table, pipeline |
workflows/<name>/README_cn.md |
Same as above (Chinese) |
workflows/<name>/AGENTS.md |
Available skills list, recommended sequences |

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.

add-new-skills-to-workflow is a skill published in the GitHub repository nicepkg/ai-workflow (283 stars, last pushed 7mo ago), licensed MIT. It adds 69 tokens to every session and 1,054 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.
