Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

markdown scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

markdown Skill

L0: One-line Summary

Create Markdown documents (.md) using the Write tool, with proper file output and delivery to the user.

L1: Overview and Use Cases

Capability

markdown is a Procedural Skill that serves as the default document format when users request written deliverables without specifying Word/PDF/Excel/PPT. Markdown files can be directly opened and edited in DesireCore's built-in SuperDoc editor.

Use Cases

  • The user asks to create a report, summary, plan, outline, or any written document
  • The user asks to organize information into a table or list
  • The user asks to draft a memo, meeting notes, weekly report, etc.
  • The user asks to "write something" or "make a document" without specifying format
  • The user explicitly mentions "md", "markdown", or ".md"

L2: Detailed Specification

Output Rule (CRITICAL — violation = task failure)

After you create a .md file using the Write tool, you MUST complete these two final steps:

Final Step 1: Output a text reply containing:

  • A brief summary of what was created or changed
  • The file's full absolute path (copied from the Write tool result)

Template:

已为你创建「文档标题」,简要说明内容。

📄 文件位置:`/full/absolute/path/filename.md`

Final Step 2: Call SendUserMessage with the file as attachment. This MUST be your very last action. Do NOT output any text after this call.

SendUserMessage({
  message: "📄 点击下方附件打开文件",
  attachments: ["/full/absolute/path/filename.md"]
})
Correct vs Wrong
  • ✅ Write → text reply (with absolute path) → SendUserMessage (with attachment) → done
  • ❌ Write → text reply without absolute path
  • ❌ Write → no SendUserMessage
  • ❌ Write → SendUserMessage → more text output (e.g. "任务完成")
  • ❌ No Write at all, content output directly in chat
Forbidden
  • Outputting the full document content directly in the chat reply instead of writing to a file
  • Saying "好的,已完成" / "整理好了" / "以下是内容" without calling Write tool
  • Only giving a filename (e.g. "报告.md") without the full absolute path
  • Not calling SendUserMessage to deliver the file attachment
  • Outputting any text after SendUserMessage
  • Writing memory files about the document creation task — creating/editing a document is a one-time task, NOT a user preference or fact to remember

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
