What it does
Sciagent Skill Creator is an agent skill from jaechang-hits/SciAgent-Skills. Scaffold a new SciAgent-Skills entry. Picks pipeline/toolkit/database/guide template, creates skills/{category}/{name}/SKILL.md with valid frontmatter, appends the registry.yaml entry, runs validation. Enforces name uniqueness, kebab-case, description keyword rules, schema rules from AGENTS.md. TRIGGER when user says (any language): "add a SciAgent skill", "add a skill for <X", "create new skill", "create a SKILL.md for <X", "scaffold a skill", "new skill entry", "register a skill", "신규 skill 추가", "스킬 만들어줘", "스킬…
Its SKILL.md is about 2.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/scaffold.py` and `scripts/validate_description.py`).
It sits in Agent Workflows, covering Skill authoring, Agent instruction files and Project scaffolding. The repository describes itself as: 197 bioinformatics & life science skills for Claude Code and AI agents — BixBench 92.0% accuracy. RNA-seq, single-cell, drug discovery, proteomics, and more. Powers OmicsHorizon.
When your agent uses it
- User says (any language): add a SciAgent skill
- Add a skill for <X
- Create new skill
- Create a SKILL.md for <X
Example prompts
- “add a SciAgent skill”
- “add a skill for <X”
- “create new skill”
- “/sciagent-skill-creator”
Requirements
- Python 3
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Topic — concrete tool/library/concept name. Reject vague topics ("ML stuff") with a clarifying question.
- Sub-type — pipeline | toolkit | database | guide. Use the decision rule from AGENTS.md Step 1b. If unsure, ask the user.
- Category — primary category directory. List the table from AGENTS.md Step 2 if the user is unsure.
- Entry name — kebab-case slug. Convention: {tool-name}-{purpose} (e.g., pydeseq2-differential-expression). Confirm with the user.
- License — underlying tool's license. Default to CC-BY-4.0 for original prose-only content.
- Description — 1-2 sentences, max 1024 chars. Lead with tool/domain keyword in the first 120 chars. Anti-patterns are in AGENTS.md Step 5…
- Tags (optional) — only if the entry meaningfully spans multiple categories (e.g., literature DB stored under scientific-writing, tag with…
What it can do on your machine
Read from SKILL.md and the folder at commit 82c862c. 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 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
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
Sciagent Skill Creator loads about 2.3k tokens when it runs. Until then it costs about 229 tokens; SKILL.md has 1,069 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.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,069 words (~2,292 tokens).
“Repo-local scaffolder for skills/ entries. Mechanizes the boilerplate from AGENTS.md Steps 1, 2, 4, 5, 6 so authoring effort stays on content (When to Use, Workflow, Recipes, References) and not on field plumbing.”
