What it does

Verify Al E2E is an agent skill from microsoft/AL, published by the product's own GitHub organization. Orchestrates the smallest production-path AL reproduction through the workflow-installed public prerelease ALTool and BCInsider sandbox.

Its SKILL.md is about 240 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering End-to-end testing. 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.

When your agent uses it

  • Tasks that involve End-to-end testing

Example prompts

  • “Use the verify-al-e2e skill to orchestrate the smallest production-path AL reproduction through the workflow-installed public prerelease ALTool and…”
  • “/verify-al-e2e”

Workflow steps

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

  1. Invoke verify-prerelease-altool.
  2. Create the smallest fixture with create-al-project.
  3. Select the required path
  4. Run the reported case and a valid control case when feasible.
  5. Preserve ALTool version, BC artifact version, commands/skill calls, diagnostics, exit codes, and
  6. Keep all fixtures and output under $env:RUNNER_TEMP and remove them after evidence is captured.

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.

    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

Verify Al E2E loads about 241 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 87 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~241

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.
