Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

Example prompts

  • “Use the download-al-symbols skill to download exact Business Central symbol packages for a temporary AL reproduction project through the installed…”
  • “/download-al-symbols”

Requirements

  • PowerShell

What it can do on your machine

Read from SKILL.md and the folder at commit 872adad. 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 script files (PowerShell), which the agent can run.

    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

Download Al Symbols loads about 273 tokens when it runs. Until then it costs about 64 tokens; SKILL.md has 89 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~64
When it runs · the whole SKILL.md, loaded when a task matches
~273

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.

argument-hint
<project-folder>

Run the deterministic wrapper:

powershell
& .\.github\skills\download-al-symbols\Invoke-DownloadAlSymbols.ps1 `
    -ProjectPath <project-folder>

The wrapper uses only the prerelease ALTool installed by the workflow at ALTOOL_PATH. It invokes ALTool's symbol-download capability non-interactively with the sandbox connection, tenant, and credentials provided by the workflow, writes packages to <project>\.alpackages, and fails unless at least one package is present.

For symbol download, do not invoke alc.exe, launch or script an MCP server yourself, or call /dev/packages directly. Use run-al-mcp-tool separately when the issue itself concerns an MCP tool. After the wrapper succeeds, compile through ALTool and pass the populated .alpackages path.
