What it does

Markdown is an agent skill from facioquo/stock-indicators-dotnet. Format and lint Markdown in this repository against GitHub Flavored Markdown and its markdownlint-cli2 configuration — headers, lists, code fences, callouts (VitePress containers on docs-site pages, GitHub alerts elsewhere), allowed HTML, reference syntax, and line wrapping. Use when creating or editing any .md file, when markdownlint or the CI "Lint markdown" step reports errors, or when changing a .markdownlint-cli2.jsonc file.

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `references/formatting-standards.md`, `references/setup-guide.md` and `references/validation-checklist.md`).

It sits in Business, Finance & HR, covering Static sites and blogs, Linting and formatting and Markdown. It works with GitHub and VitePress. The repository describes itself as: Stock Indicators for .NET is a C NuGet package that transforms raw equity, commodity, forex, or cryptocurrency financial market price quotes into technical indicators and trading… The licence is Apache-2.0.

When your agent uses it

  • Editing any .md file
  • The CI Lint markdown step reports errors
  • Changing a .markdownlint-cli2.jsonc file

Example prompts

  • “Lint markdown”
  • “/markdown”

Requirements

  • Node.js
  • A Bash shell

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Auto-fix
  2. Review what the linter cannot see
  3. Verify

What it can do on your machine

Read from SKILL.md and the folder at commit 136113b. 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/ (Shell), which the agent can run.

    Shell commands in SKILL.md call:

    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    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

Markdown loads about 812 tokens when it runs, and up to ~2.8k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 384 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~111
When it runs · the whole SKILL.md, loaded when a task matches
~812
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.8k

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.

Format and lint Markdown in this repository against GitHub Flavored Markdown and its markdownlint-cli2 configuration — headers, lists, code fences, callouts (VitePress containers on docs-site pages, GitHub alerts elsewhere), allowed HTML, reference syntax, and line wrapping. Use when creating or editing any .md file, when markdownlint or the CI "Lint markdown" step reports errors, or when changing a .markdownlint-cli2.jsonc file.

Markdown authoring

Markdown mechanics only: syntax, structure, and reference form. The structure of an indicator page on the docs site belongs to the documentation skill.

Load the formatting standards before writing or restructuring a file; they hold the rules a linter cannot check.

Workflow

Step 1: Auto-fix
bash
npx markdownlint-cli2 --no-globs path/to/file.md --fix

Run from the repository root. From a subfolder the root .markdownlint-cli2.jsonc is not read, and default rules such as MD013 line length fire. --no-globs lints only the paths you pass; without it the config's globs add every Markdown file in the repository.

Auto-fix handles bullet style, ATX headers, blank lines around headers and fences, and list indentation. It does not handle sentence case, hard-wrapped paragraphs, link targets, callout syntax, or reference form.

Step 2: Review what the linter cannot see

Apply the formatting standards. The usual misses:

  • Headers — sentence case ("How to use", not "How To Use").
  • Line wrapping — each paragraph, list item, and table cell is one source line. MD013 is off, so the linter never flags a hard wrap.
  • Callouts — ::: containers on docs-site pages, GitHub alerts everywhere else.
  • References — Markdown links for files; skills, tools, and agents in prose.
Step 3: Verify
bash
npx markdownlint-cli2 --no-globs path/to/file.md

Zero errors required. CI runs echo y | npx markdownlint-cli2 over the whole repository; the VS Code tasks Lint: Markdown and Lint: Markdown (fix) do the same. Then work through the validation checklist for the semantic checks.

Tooling and configuration

Changing a .markdownlint-cli2.jsonc file, adding an allowed HTML element, or diagnosing why a file is or is not linted → load the markdown tooling reference.

Do not do these

  • Do not hard-wrap prose at a column. A wrapped paragraph turns every later edit into a reflow diff.
  • Do not put a ::: container in Markdown that GitHub renders; it shows as literal text. Do not put a GitHub alert (> [!NOTE]) on a docs-site page; the site convention is containers, which the build converts to alerts for the .md twins agents read.
  • Do not use #file:, #skill:, or #tool: markers in any file.
  • Do not link from a skill into another skill's folder or up to an AGENTS.md; name the other skill in prose.
  • Do not add a Last updated: footer, trailing --- separator, or date stamp. Git history records when a file changed.
  • Do not silence a rule with an inline <!-- markdownlint-disable --> when restructuring the content fixes it.

Markdown is an agent skill from facioquo/stock-indicators-dotnet. Format and lint Markdown in this repository against GitHub Flavored Markdown and its markdownlint-cli2 configuration — headers, lists, code fences, callouts (VitePress containers on docs-site pages, GitHub alerts elsewhere), allowed HTML, reference syntax, and line wrapping.

When should I use Markdown?

Markdown fits situations like: editing any .md file; the CI Lint markdown step reports errors; changing a .markdownlint-cli2.jsonc file.

How do I install Markdown in Claude Code?

Run `npx skills add facioquo/stock-indicators-dotnet --skill markdown -a claude-code`. Or copy the skill folder (.agents/skills/markdown in facioquo/stock-indicators-dotnet) into .claude/skills/markdown in your project. Claude Code loads it when a task matches its description.

How do I install Markdown in Codex?

Run `npx skills add facioquo/stock-indicators-dotnet --skill markdown -a codex`. Or copy the skill folder (.agents/skills/markdown in facioquo/stock-indicators-dotnet) into .agents/skills/markdown in your project. Codex loads it when a task matches its description.

Can I use Markdown in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add facioquo/stock-indicators-dotnet --skill markdown -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/markdown, .gemini/skills/markdown, .github/skills/markdown and .opencode/skills/markdown in your project.

What does Markdown need to run?

Going by SKILL.md and its folder, Markdown needs a shell for the scripts in its folder and the command-line tools its instructions call (npx). Our summary lists: Node.js; A Bash shell.

Does Markdown access the network?

SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Markdown safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Markdown use?

Markdown is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Markdown use?

About 812 tokens (SKILL.md is roughly 3.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2k tokens, read only when the agent opens those files.

What are the alternatives to Markdown?

Skills that share tags, products or a category with Markdown: Mdzilla (pi0/mdzilla, 110 stars), Retail Trading Manual Writer (digoal/blog, 8.6k stars), Trading Manual Writer (digoal/blog, 8.6k stars) and Wiki Ado Convert (microsoft/skills, 3.1k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Markdown?

facioquo (a GitHub organization) maintains it in facioquo/stock-indicators-dotnet, which has 1,247 GitHub stars. The repository holds 10 skills in this directory. The repository was last updated on October 6, 2026.
