X2strategy

What it does

When your agent uses it

• The user wants to analyze a quant paper
• Extract trading strategies
• Generate strategy code
• Search for papers

Example prompts

• “look at this paper”
• “what strategies does this use”
• “implement this strategy”
• “/x2strategy”

Requirements

• Python 3
• A credential in DEEPSEEK_API_KEY
• A credential in OPENROUTER_API_KEY

Workflow steps

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

What it can do on your machine

Read from SKILL.md and the folder at commit e9cd907. 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 1 file in scripts/ (Python, from the files we listed), which the agent can run.

  Shell commands in SKILL.md call:

  • uv
  • just
  • pip

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

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • platform.deepseek.com
  • openrouter.ai

  Also links to:

  • docs.litellm.ai

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • DEEPSEEK_API_KEY
  • OPENROUTER_API_KEY
  • OPENAI_API_KEY
  • ANTHROPIC_API_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

X2strategy loads about 4.2k tokens when it runs, and up to ~29k if it reads all its reference files. Until then it costs about 249 tokens; SKILL.md has 1,503 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~249

When it runs · the whole SKILL.md, loaded when a task matches

~4.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~29k

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.

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.
