What it does

Skill Creator is an agent skill from xuzhougeng/wisp-science. Create, update, validate, and evaluate Wisp skills. Use when authoring a project-local or installable skill, refining its trigger description, adding deterministic scripts or Python/R runtime sidecars, or testing whether another Agent can follow the workflow.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/package_skill.py` and `scripts/quick_validate.py`).

It sits in Agent Workflows, covering Skill authoring. It works with Python. The repository describes itself as: Open-source, local-first desktop AI research workbench for scientific computing with Python/R, MCP bioinformatics tools, SSH/WSL/GPU runtimes, and OpenAI/Anthropic models. The licence is AGPL-3.0.

What it can do on your machine

Read from SKILL.md and the folder at commit 2ba143b. 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.
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 1.3k tokens when it runs. Until then it costs about 68 tokens; SKILL.md has 562 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~68
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k

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

The full file from xuzhougeng/wisp-science at commit 2ba143b, republished under its AGPL-3.0 licence (© xuzhougeng). 562 words, ~1,255 tokens.

name: skill-creator
description: Create, update, validate, and evaluate Wisp skills. Use when authoring a project-local or installable skill, refining its trigger description, adding deterministic scripts or Python/R runtime sidecars, or testing whether another Agent can follow the workflow.

Create Wisp skills

Author project-local skills under .wisp/skills/<name>/. Wisp also discovers bundled skills, user-installed skills, and paths configured by WISP_SKILLS_PATH, but only normal project paths are directly writable through Agent file tools.

Structure

text

<skill-name>/
├── SKILL.md               # frontmatter trigger + procedure body
├── runtime.py             # optional helpers for the persistent Python runtime
├── runtime.r              # optional helpers for the persistent R runtime
├── scripts/               # optional standalone deterministic programs
├── references/            # optional detailed domain material
└── assets/                # optional output templates or static inputs

Keep SKILL.md concise. Put triggering information in frontmatter description; put essential procedure in the body; move detailed variants to one-level-deep references. Add only resources the workflow actually uses.

Workflow

Define concrete user requests that should trigger the skill and the expected outputs.
Search existing skills before creating a duplicate.
Choose a lowercase hyphenated name and create .wisp/skills/<name>/SKILL.md with write.
Add reusable scripts before writing long inline code examples. Execute every new script on representative local data.
Add root-level runtime.py and/or runtime.r when helpers need to work with persistent interpreter state. The rendered skill supplies a one-time loading instruction for each file: exec(compile(...)) through python, or source(..., local = TRUE) through r. Skill loading itself does not execute them or inject Wisp tools. These files run inside the selected runtime; do not invoke them as standalone CLI scripts.
Validate structure with this skill's scripts/quick_validate.py <skill-directory>.
Refresh or reopen the project if the new skill does not yet appear, then find it with search_skills and load it with use_skill.
Exercise the skill on realistic tasks. When explicit Wisp delegation is available, use a fresh bounded task with only the skill path and user-style request; do not leak the expected answer into the evaluation prompt.

For a user-wide installation, ask the user to install the validated folder via Settings → Skills. There is no Agent-side publish, overwrite, or delete API.

Frontmatter

At minimum include:

yaml

---
name: my-skill
description: Perform X. Use when the user asks for Y, Z, or related output.
---

The folder name and name should match. The description is the primary trigger; state both what the skill does and when it should be selected.

Runtime sidecar rules

Keep top-level code definition-only:

allow imports, function definitions, and literal constant assignments;
defer optional third-party imports into function bodies;
do not run work, access the network, or modify files at load time;
do not depend on injected Agent, Run, credential, artifact, or model objects;
pass paths and configuration explicitly;
use the corresponding python or r tool after loading; reload when that runtime restarts or the conversation/execution context changes;
Python and R retain separate state; use prefixed names to avoid collisions with other helpers within each language's namespace;
Python loading runs in __main__, so put self-checks in explicitly called functions rather than a __main__ guard.

Use scripts/ when a helper is a standalone CLI, needs argument parsing, or should run through run_in_context. Choose by state reuse and execution needs, not file length. scripts/runtime.py and scripts/runtime.r are ordinary scripts; only the reserved root-level filenames get runtime loading guidance.

Bundled scripts

scripts/quick_validate.py <skill-dir> — checks frontmatter shape, kebab-case naming, folder/name match, and length limits; prints every problem at once.
scripts/package_skill.py <skill-dir> [out-dir] — validates, then zips the folder into <name>.skill for user-wide installation, skipping build junk and a root-level evals/ folder.

To evaluate a skill, run it on realistic tasks yourself (step 8 above) and keep evaluation artifacts out of the skill folder unless they are intentional reusable resources.

Wisp boundaries

search_skills and use_skill do not edit the catalog.
Project file tools cannot manage user-wide installed skills outside granted workspace paths.
run_in_context executes deterministic work; it does not publish skills or call models.
Specialist creation is separate. Load customize and use save_specialist only when that explicit tool is advertised.
