  • SKILL.md covers Lifecycle and Landmines
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Daily Build Updater is an agent skill from vchelaru/FlatRedBall. Glue daily-build self-update and its Windows replacement helper. Triggers: DoInstallDailyBuild, DailyBuildUpdateLauncher, GlueDailyBuildUpdate.log, GlueDailyBuild.zip.

Its SKILL.md is about 420 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 Game Development. It works with PowerShell. The repository describes itself as: Cross-platform 2D game engine focused on ultimate productivity built in .NET. The licence is MIT.

When your agent uses it

  • Game Development work in your project

Example prompts

  • “/daily-build-updater”

What it can do on your machine

Read from SKILL.md and the folder at commit fa654ab. 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

Daily Build Updater loads about 420 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 137 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~420

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.

Lifecycle

FileResponsibility
FRBDK/Glue/Glue/Plugins/EmbeddedPlugins/AboutPlugin/AboutViewModel.csConfirmation, download, staging, and helper hand-off.
FRBDK/Glue/Glue/Plugins/EmbeddedPlugins/AboutPlugin/DailyBuildUpdateLauncher.csGenerates the detached PowerShell replacement helper.
FRBDK/Glue/Glue/Plugins/EmbeddedPlugins/AboutPlugin/DailyBuildUpdateDiagnostics.csBounded lifecycle log at %LOCALAPPDATA%\FlatRedBall\GlueDailyBuildUpdate.log.
FRBDK/Glue/Tests/GlueUnitTests/AboutPlugin/DailyBuildUpdateLauncherTests.csScript parsing, path normalization, lifecycle, and diagnostic tests.

The running editor stages GlueDailyBuild.zip beside its installation, starts the helper, exits, then the helper deletes the old directory, moves staging into place, and restarts Glue.

Landmines

  • FileManager.GetDirectory supplies a trailing separator. Apply Path.TrimEndingDirectorySeparator before deriving the helper working directory; otherwise PowerShell runs inside and locks the directory it must delete.
  • Generated PowerShell must be parsed by a real powershell.exe test. In interpolated strings, delimit a variable immediately followed by : as ${variable}:.
  • Keep the lifecycle log. Its last successful phase separates host hand-off, helper startup/parsing, Glue exit, file replacement, and restart failures. On a real replacement failure, Restart Manager lock owners belong in that log.
