At a glance

Manually launching a built GlueFormsCore.exe to repro/verify an editor UI bug (layout, startup state, first-launch behavior).

  • Game Development work in your project
  • SKILL.md covers Landmines and Reusable pattern
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Glue Manual Repro is an agent skill from vchelaru/FlatRedBall. Manually launching a built GlueFormsCore.exe to repro/verify an editor UI bug (layout, startup state, first-launch behavior). Triggers: GlueFormsCore.exe, %AppData%\GlueFormsCore, settings.xml, GlueLayoutSettings.xml, simulating first launch.

Its SKILL.md is about 700 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. 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

  • “/glue-manual-repro”

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

Glue Manual Repro loads about 697 tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 330 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~65
When it runs · the whole SKILL.md, loaded when a task matches
~697

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
Manually launching a built GlueFormsCore.exe to repro/verify an editor UI bug (layout, startup state, first-launch behavior). Triggers: GlueFormsCore.exe, %AppData%\GlueFormsCore, settings.xml, GlueLayoutSettings.xml, simulating first launch.

For investigating a UI/layout bug that a unit test can't pin alone (timing, first-launch state, window rendering) — driving the real GlueFormsCore.exe yourself is fine; the process doc's "don't drive the tool yourself" rule is about the final user-facing manual-test step, not internal repro.

Landmines

  • Build Glue with All.sln, not Glue.csproj alone. A Glue.csproj-only build boots with no plugins loaded (Explorer tree, property grid, etc. all silently missing) — the window looks badly broken in a way that has nothing to do with the bug you're chasing. Costs a full rebuild cycle to notice.
  • settings.xml's LastProjectFile must be the .csproj, not the .gluj. Glue opens it via Microsoft.Build.Evaluation.Project; a .gluj path throws a real "Could not load the project" popup.
  • User profile lives at %AppData%\GlueFormsCore\settings.xml and GlueLayoutSettings.xml. Back both up before simulating a fresh/first-launch profile (delete or rewrite them), restore after — these are the developer's real Glue preferences, not scratch files.
  • A backgrounded/unfocused window doesn't repaint. Program.cs forces RenderOptions.ProcessRenderMode = SoftwareOnly; a screenshot of an occluded or non-foreground window shows stale/blank content. Bring it to the foreground and maximize (ShowWindow/SetForegroundWindow via P/Invoke in PowerShell) immediately before capturing.
  • A project auto-load on startup can take minutes, not seconds (MSBuild restore, codegen) — a window title still reading generic "FlatRedBall Editor" (no project path) means it hasn't finished; don't read the UI state as final until the title shows the loaded .csproj path.
  • exitwhenquiet may never fire. The automation hook (MainGlueWindow.StartExitWhenQuietWatcherIfRequested) exits only once TaskManager.Self.AreAllAsyncTasksDone has held for N seconds, and on some projects that never happens — Glue loads fine and then just stays open (issue #2053). Don't build a headless verify loop on a clean exit; launch, wait for the title to show the .csproj, kill, and assert on files written.

Reusable pattern

Self-serve-log via a temporary File.AppendAllText probe in the suspect code path (see the self-serve-logging skill), launch the exe from Bash/PowerShell, drive it headlessly where possible (writing settings.xml directly beats simulating clicks), then read the log — don't ask the user to transcribe anything.
