What it does

Langalpha Doc is an agent skill from ginlix-ai/LangAlpha. How the platform under you works: the computer and its workspaces, files and what survives a restart, conversation transcripts, saved tool results, memory, and adding skills, MCP servers, brokerages or plugins. Read it when the user points back at an earlier conversation, when something is missing or behaves unexpectedly, and before adding any of those.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/computer.md`, `references/files.md` and `references/history.md`).

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: Claude Code for Financial Market. The licence is Apache-2.0.

When your agent uses it

  • Points back at an earlier conversation
  • Something is missing
  • Behaves unexpectedly
  • Before adding any of those

Example prompts

  • “/langalpha-doc”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit e05bd91. 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

Langalpha Doc loads about 816 tokens when it runs, and up to ~9.6k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 440 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~816
With references · SKILL.md plus every file in references/, read only if the agent opens them
~9.6k

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.

description
How the platform under you works: the computer and its workspaces, files and what survives a restart, conversation transcripts, saved tool results, memory, and adding skills, MCP servers, brokerages or plugins. Read it when the user points back at an earlier conversation, when something is missing or behaves unexpectedly, and before adding any of those.

How LangAlpha Works

You run on a computer: one sandbox machine that belongs to the user. Each of the user's workspaces on it is a folder, side by side at the computer root; yours is your working directory, so the root is ... A thread is one conversation in one workspace, and a turn is one user message and everything done to answer it. Workspaces on one computer share its disk, OS user, CPUs, /tmp and installed packages, and can read each other's folders.

Reference files

  • The user points back at an earlier conversation or at work done in another thread or workspace; a compaction summary; a background task's steps; a tool result saved to a file: .agents/skills/langalpha-doc/references/history.md.
  • Where things live, how a path resolves, why Grep or Glob missed a file, memory and memo storage, what the user sees in the file panel: .agents/skills/langalpha-doc/references/files.md.
  • Processes, output and timeouts, CPUs and disk, installed packages, what survives a stop or a rebuild, data-server tools from code, secrets: .agents/skills/langalpha-doc/references/computer.md.
  • Installing, writing or changing a skill, here or for every workspace: .agents/skills/langalpha-doc/references/skills.md.
  • The user wants a new data source, MCP server, brokerage connection or plugin, a server needs a key, or a server you expected is missing: .agents/skills/langalpha-doc/references/plugins.md.

Traps

  • Every ExecuteCode and Bash call is a fresh process started in your workspace folder: Python variables, cd and export do not carry to the next call.
  • When ExecuteCode fails you get its stderr, not what it printed before the crash.
  • The file tools read a leading slash as your workspace folder; open() and Bash read it as the real filesystem root. Glob, Grep and Write print workspace files with a leading slash (/task/file.md), so drop it before pasting a path into code.
  • Grep skips hidden and git-ignored files and folders, .agents/ included, unless path points inside one.
  • Only workspace folders are backed up, and not their virtual environments. Installed packages, the computer root and /tmp survive a stop but not a rebuild of the computer.
  • A turn is written to its thread's transcript when it completes, so do not look there for the turn in progress.
  • Memory, memos, the profile, workflows and automations are held by the server. Bash and code reach them only through the file mount, where a save the server refuses shows under NOT SAVED in the result, not in the exit status. Without the mount, a command naming a memory, memo or automations path is refused before it runs.
  • In a markdown file, an image path resolves from the workspace folder, not from the file's own folder.
  • plt.show() output goes nowhere. Save charts with savefig into <task>/charts/ and link the file.
