What it does
Skill Creator is an agent skill from Chevey339/kelivo. Create or improve skills, turn a conversation into reusable SKILL.md instructions, and validate their behavior. Use when the user asks to build, revise, or test a skill.
Its SKILL.md is about 1.3k 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, covering Skill authoring and Cross-platform mobile apps. It works with Flutter, Android and iOS. The repository describes itself as: A Flutter LLM Chat Client. Support Mobile & Desktop. The licence is AGPL-3.0.
When your agent uses it
- The user asks to build
- Tasks that involve Skill authoring
- Tasks that involve Cross-platform mobile apps
Example prompts
- “/skill-creator”
Requirements
- Python 3
- Node.js
What it can do on your machine
Read from SKILL.md and the folder at commit df60f74. 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 (its code samples are markdown).
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 46 tokens; SKILL.md has 674 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); files beside SKILL.md are not scanned.

Skill Creator
Help the user turn a repeatable task into a skill that works in Kelivo. Write instructions and explain the result in the user's language.
Understand the task
Use the current conversation first: extract the goal, inputs, expected output, important corrections, and tools that actually worked. Ask only for missing details that would change the skill. A clear request is enough to start drafting.
For an update, read the existing SKILL.md and the resources affected by the change. Preserve the user's workflow and unrelated content. Treat examples as examples; only turn a preference into a general rule when the user wants it.
Write the skill
A skill is a directory with a UTF-8 file named exactly SKILL.md. Begin with
YAML frontmatter containing name and description, followed by Markdown:
---
name: meeting-actions
description: Turn meeting notes into decisions, action items, and open questions. Use when the user asks to summarize a meeting or extract follow-up tasks.
---
# Meeting Actions
Read the provided notes and separate decisions, action items, and open questions.
For each action, include the owner and deadline when given; mark missing values
as unspecified. Keep tentative proposals distinct from agreed decisions.Choose a short lowercase name using letters, digits, and hyphens, at most 64 characters. Use the same name for its directory. Write a concise description that says what the skill does and when to use it; Kelivo shows only the first 200 characters in the model's skill list. Put detailed instructions in the body.
Include the task-specific decisions, output shape, and completion criteria that improve the result. Keep the entrypoint focused. Add these directories only when the task needs them:
references/: detailed guidance consulted for a particular case. Link each reference from SKILL.md and say when to read it.scripts/: reusable, deterministic operations. Check the required runtime is available and execute new or changed scripts against a small example.assets/: templates or other files used in the output.
Use relative paths for resources. Avoid private absolute paths, credentials, and instructions that assume a particular developer's computer. Refer to configured environment variables by name when credentials are needed. Dependencies belong in the instructions only if the workflow needs them; a Markdown-only skill requires neither Python nor Node.js.

Deliver in Kelivo
Use the tools and path zones shown in the current conversation. Kelivo supports SKILL.md instructions and supporting files; Codex/Claude-specific CLI commands, plugin manifests, subagents, and evaluation runners are not prerequisites.
- Workspace with a working shell: install directly into Kelivo's skills
directory using the skills path provided in the workspace context (
/skillsin a sandbox, the supplied host path in native mode). For skill creation and updates, useshell:write_fileandedit_filetreat this directory as read-only. For a new skill, choose an unused directory matching its name; for an update, use the existing directory and preserve unrelated files. Write supporting files there with their relative paths intact, then write the complete SKILL.md last. Kelivo rescans installed skills after shell commands, so saving here installs the skill without a separate import. - No workspace or no working shell: installed skills remain read-only. Return the complete SKILL.md in a fenced Markdown block as a draft. Explain that direct installation requires a bound workspace with a working shell.
After installation, read back SKILL.md and its referenced files. Link the saved
entrypoint as kelivo://skills/<skill-directory>/SKILL.md, using the actual
directory name and URI-encoding each path component. Claim installation only
after saving and verification succeed. New skills are enabled by default; an
assistant or conversation with an explicit skill selection may need the new
skill selected.
Validate and refine
Before delivery, check that name and description are present, frontmatter closes before the body, referenced files exist, and the instructions only depend on available tools or explicitly documented prerequisites. Finish or remove draft placeholders. Check that the skill directory contains all required files.
Use a representative request to check the intended behavior and a nearby request that should not trigger the skill. For outputs with objective requirements, check those requirements; for subjective work, show a sample for user feedback. Run a small example when the necessary tools and inputs are available. Distinguish checks actually run from suggested test prompts, and keep any test outputs outside the skill directory unless they are useful maintained examples.
End with what the skill does, where it was installed or what is needed to install the draft, and what was verified. Make later changes from observed behavior and user feedback.
