When your agent uses it

  • Converting plain-language strategy ideas into supported
  • Needs-clarification
  • Unsupported verdicts
  • When drafting strategy run

Example prompts

  • “/lo2cin4bt-strategy-builder”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Use response_language from the PM packet when present; otherwise infer it from the latest user message.
  2. If the user writes in Chinese or asks for Chinese, write Traditional Chinese for all non-specialist wording.
  3. Keep code identifiers, file paths, commands, schema keys, agent/skill names, ticker symbols, provider names, and standard finance/quant…
  4. Return response_language in the output packet. When writing repo-local reports, apply the same language policy to the report body.

What it can do on your machine

Read from SKILL.md and the folder at commit d2e0863. 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

    Shell commands in SKILL.md call:

    • uv

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

  • Network

    No URLs in SKILL.md. Its commands use uv, 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

Lo2cin4bt Strategy Builder loads about 2.2k tokens when it runs. Until then it costs about 66 tokens; SKILL.md has 940 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~66
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

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.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 940 words (~2,225 tokens).

“Translate strategy concepts into precise executable config semantics that compile into the shared Rust engine without family-specific runtime code.”
