What it does

Longbridge Portfolio is an agent skill from helsome/folio. Account assets, equity and fund positions, P&L, cash flow records, account statements, margin ratios, buy-power estimates, order management, and DCA recurring investments via Longbridge (most require Trade permission). Frameworks: portfolio diagnosis, rebalancing, asset allocation, risk analysis (VaR/CVaR), performance attribution, and tax-loss harvesting. Triggers: "持仓", "账户", "盈亏", "资产", "对账单", "下单", "买入", "卖出", "撤单", "定投", "组合诊断", "再平衡", "资产配置", "风险分析", "绩效归因", "税损收割", "持倉", "賬戶", "盈虧", "對賬單", "下單", "買入"…

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 20 other files, including reference files (for example `references/asset-allocation.md`, `references/assets.md` and `references/bank-cards.md`).

It sits in Sales & Support, covering E-commerce operations and Financial analysis. It works with Longbridge and OpenAI. The repository describes itself as: 本地优先的 AI 投资研究工作台(AI investment research workbench),支持深度调研、证据化投资论点、投资组合风险分析、自选股与 Pi Agent 副驾驶。 The licence is MIT.

When your agent uses it

  • Tasks that involve E-commerce operations
  • Tasks that involve Financial analysis

Example prompts

  • “positions”
  • “portfolio”
  • “statement”
  • “/longbridge-portfolio”

What it can do on your machine

Read from SKILL.md and the folder at commit 3a17eca. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    No URLs in SKILL.md.

    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

Longbridge Portfolio loads about 1.8k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 187 tokens; SKILL.md has 557 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~187
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~17k

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.
