What it does

Run Al Code Analysis is an agent skill from microsoft/AL, published by the product's own GitHub organization. Runs CodeCop, PerTenantExtensionCop, UICop, or AppSourceCop against a temporary project through the public prerelease ALTool.

Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Home of the Dynamics 365 Business Central AL Language extension for Visual Studio Code. Used to track issues regarding the latest version of the AL compiler and developer tools… The licence is MIT.

Example prompts

  • “/run-al-code-analysis”

Workflow steps

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

  1. Invoke verify-prerelease-altool.
  2. Invoke download-al-symbols when the project has symbol references.
  3. Create a temporary .code-workspace through
  4. Run the requested analyzer with ALTool workspace compile
  5. Preserve the exact diagnostics and exit code. A missing analyzer, ruleset, or symbol package is an
  6. Exercise both the reported case and the nearest valid control case when feasible.

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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are powershell).

    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

Run Al Code Analysis loads about 302 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 88 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~302

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.

  1. Invoke verify-prerelease-altool.
  2. Invoke download-al-symbols when the project has symbol references.
  3. Create a temporary .code-workspace through:
    powershell
    & $env:ALTOOL_PATH workspace create $workspaceFile $projectPath
  4. Run the requested analyzer with ALTool workspace compile:
    powershell
    & $env:ALTOOL_PATH workspace compile $workspaceFile `
    --packagecachepath (Join-Path $projectPath '.alpackages') `
    --analyzers PTECop `
    --outfolder $outputFolder `
    --errorlogdirectory $errorLogFolder
    Select only the reported analyzer from AppSourceCop, CodeCop, PTECop, or UICop. Use --ruleset when the issue supplies one. Never invoke alc.exe.
  5. Preserve the exact diagnostics and exit code. A missing analyzer, ruleset, or symbol package is an inconclusive setup failure, not evidence that no diagnostic exists.
  6. Exercise both the reported case and the nearest valid control case when feasible.
