artifact_markdown is a skill in win4r/MuseAI-Skills, last changed 25 Sept 2026. It is instructions only: no scripts, no named hosts and no pre-approved tools.
Build or revise a plain markdown file (md) deliverable such as notes, a README, meeting minutes, documentation, or text the user will edit or paste elsewhere. Use whenever a build task's artifact kind is markdown. Covers markdown formatting conventions and read-back verification.

Instructions only
It is instructions only: no scripts, no named hosts and no pre-approved tools.
Pattern check
Pattern check: nothing flagged · commit 38bbb45 · 3 Nov 2026
We checked every text file in this skill, at commit 38bbb45 on 3 Nov 2026, against 45 published patterns such as download-and-run commands, hidden text and credential access. We don't run the skill, we don't read the web pages it points to, and we can't judge everything its instructions might lead an agent to do. In published tests, pattern checks like this one missed most malicious skills. Read the skill before you install it — especially anything it asks you to download or run.
Format check
Each agent reads SKILL.md a little differently. We check the file against each one's published rules; we don't run the skill in any agent.
Agent Skills specFails
The open format from agentskills.io, held to the strictest version of each rule among the agents we check.
- Error
The name "artifact_markdown" has underscores. Names may use only a–z, 0–9 and single hyphens. N3
Fix: Use name: artifact-markdown and rename the folder to match.
- Error
The name "artifact_markdown" doesn't match its folder "markdown". The spec requires them to match. N4
Fix: Set name: markdown, or rename the folder to artifact-markdown.
- Warning
The frontmatter uses [ ] or { } values. Most agents accept them, but the spec's validator (skills-ref) rejects the file. F4
Fix: Write lists as "- item" lines and maps as indented key: value lines, without anchors or tags.
- Warning
metadata values should be text; includeInPrompt (true or false) is not. The spec's validator turns them into text; other readers may not. O4
Fix: Quote each value, for example version: "1.0".
- Note
There is no license field, so readers can't tell whether they may reuse the skill. O2
Fix: Add license: with an SPDX name such as MIT or Apache-2.0, or the name of a bundled licence file.
- Error
Claude CodePasses
Claude Code reads its own extra fields, ignores unknown ones, and still loads a skill whose frontmatter is broken, without its fields.
- Note
The name "artifact_markdown" doesn't match its folder "markdown". Claude Code shows the skill as /artifact_markdown, and the folder name also invokes it. N4
Fix: Set name: markdown, or rename the folder to artifact-markdown.
- Note
Claude apps & API uploadFails
Uploading to claude.ai or the Claude API, or packaging with Anthropic's script, accepts only the six spec fields and stops on anything else.
- Error
The name "artifact_markdown" has underscores. Anthropic's validator allows only lowercase letters, digits and hyphens. N3
Fix: Use name: artifact-markdown and rename the folder to match.
- Error
The name "artifact_markdown" doesn't match its folder "markdown". claude.ai refuses an upload whose folder name doesn't match the skill name. N4
Fix: Set name: markdown, or rename the folder to artifact-markdown.
- Note
The description is 280 characters. The claude.ai Help Center says 200 at most, though Anthropic's API docs and validator allow 1,024. D4
Fix: If the claude.ai upload refuses it, trim the description to 200 characters.
- Note
metadata values should be text; includeInPrompt (true or false) is not. The spec defines metadata as text to text. O4
Fix: Quote each value, for example version: "1.0".
- Error
OpenAI (Codex & API)Fails
Codex finds SKILL.md by its exact name and needs a description; OpenAI's Skills API checks the frontmatter against the spec and caps uploads.
- Error
The name "artifact_markdown" has underscores. OpenAI's upload follows the spec, which allows only a–z, 0–9 and hyphens. N3
Fix: Use name: artifact-markdown and rename the folder to match.
- Warning
The name "artifact_markdown" doesn't match its folder "markdown". OpenAI's own upload example uses a differently named folder, but the spec it follows says they must match. N4
Fix: Set name: markdown, or rename the folder to artifact-markdown.
- Warning
metadata values should be text; includeInPrompt (true or false) is not. OpenAI's upload follows the spec's text-to-text rule. O4
Fix: Quote each value, for example version: "1.0".
- Error
VS Code & CopilotPasses with warnings
VS Code reads skills one folder below .github/skills, .claude/skills or .agents/skills and falls back to the folder name when the name is missing or differs; GitHub's Copilot docs require the exact name SKILL.md.
- Warning
The name "artifact_markdown" has underscores. VS Code uses the folder name whenever the name differs from it. N3
Fix: Use name: artifact-markdown and rename the folder to match.
- Warning
The name "artifact_markdown" doesn't match its folder "markdown". VS Code uses the folder name, markdown, instead. N4
Fix: Set name: markdown, or rename the folder to artifact-markdown.
- Warning
