What it does

Customize is an agent skill from xuzhougeng/wisp-science. Create a Wisp specialist or author a project-local skill using the tools Wisp actually exposes. Use when the user wants a custom Agent persona, a restricted specialist loadout, a new skill, or changes to an existing project-local skill.

Its SKILL.md is about 730 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. 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.

When your agent uses it

  • The user wants a custom Agent persona
  • A restricted specialist loadout
  • Changes to an existing project-local skill

Example prompts

  • “/customize”

Requirements

  • Python 3

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Ask what single job the specialist owns and what it must not do.
  2. Draft a display name, one-line description, and concise instructions that
  3. Decide whether to inherit project skills/connectors or use explicit
  4. Show the complete proposal and obtain confirmation before creating or
  5. To edit an existing specialist, call configure with action=get and
  6. Call save_specialist with name and instructions; add description,
  7. Report the returned specialist id. Deletion, icons, and color still live

What it can do on your machine

Read from SKILL.md and the folder at commit 5eb95c9. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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

Customize loads about 729 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 369 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~62
When it runs · the whole SKILL.md, loaded when a task matches
~729

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); files beside SKILL.md are not scanned.

Customize Wisp

Wisp exposes customization through explicit tools and Settings UI. Python has no control-plane SDK. Never invent profile, connector, or skill CRUD methods.

Create a specialist

Use save_specialist only when it is advertised in the current session.

  1. Ask what single job the specialist owns and what it must not do.
  2. Draft a display name, one-line description, and concise instructions that extend Wisp's base prompt.
  3. Decide whether to inherit project skills/connectors or use explicit whitelists. Use exact installed skill names returned by search_skills. Include connector names only when the user supplied or confirmed them.
  4. Show the complete proposal and obtain confirmation before creating or updating it.
  5. To edit an existing specialist, call configure with action=get and key specialists, then save_specialist with that id. Omit id to create. Builtin instruction text cannot be replaced.
  6. Call save_specialist with name and instructions; add description, model_id, skills, or connectors only when intentionally chosen.
  7. Report the returned specialist id. Deletion, icons, and color still live under Settings → Specialists.

Omit skills and connectors to inherit project settings. An empty list is an explicit zero-access whitelist and is not equivalent to omission.

Author or update a skill

Load skill-creator. For a project-local skill, edit files under:

text
.wisp/skills/<skill-name>/SKILL.md

Use read, write, and edit. search_skills and use_skill are discovery and loading tools, not mutation tools. If a newly created project skill is not visible immediately, refresh or reopen the project so Wisp rebuilds its skill index.

For a user-wide skill, create the folder in the project first, validate it, then ask the user to install that folder through Settings → Skills. Wisp copies installed skills to its user skill directory; there is no Agent-side publish or delete interface.

Custom appearance

For a user stylesheet (hide the lead bar, restyle chat, override tokens), load custom-theme. Write CSS that uses documented tokens, then apply it with configure set custom_css or ask the user to import the file under Settings → Appearance.

Boundaries

  • Do not modify Wisp's SQLite store directly.
  • Do not use python, shell, or run_in_context to bypass Settings or tool authorization.
  • Do not promise conversation identity switching; the user selects specialists through Wisp's UI.
  • Do not claim connector enumeration when no connector-management tool is advertised.
