What it does

Fieldworks Winforms To Avalonia Migration is an agent skill from sillsdev/FieldWorks. End-to-end playbook for migrating any FieldWorks WinForms UI (DataTree slices, XMLViews browse/table, dialogs, choosers, launchers, shell panes) to Avalonia using the established detail/seam architecture. Use whenever planning, implementing, or reviewing WinForms-to-Avalonia work — including seam extraction, region composition, owned controls, plugin editors, parity evidence, or retiring legacy UI — even if the request only says port, modernize, replace WinForms, or new Avalonia view. Also use after finishing a…

Its SKILL.md is about 3.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/architecture-patterns.md`, `references/control-exemplar-map.md` and `references/lessons-learned.md`).

It sits in Product & Project Management, covering Retrospectives. It works with Avalonia. The repository describes itself as: FieldWorks is a suite of software tools for language and cultural data, with support for complex scripts.

When your agent uses it

  • Reviewing WinForms-to-Avalonia work — including seam extraction
  • Region composition
  • Parity evidence
  • Retiring legacy UI — even if the request only says port

Example prompts

  • “/fieldworks-winforms-to-avalonia-migration”

Workflow steps

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

  1. Inventory and scope. Identify the legacy UI, its entry points,
  2. Characterize before refactor. Lock current behavior in executable
  3. Extract seams. Reuse the existing contracts in
  4. Select controls. Look the control up in
  5. Compose the region. Walk the compiled IR in a composer, project into
  6. Wire the host. Explicit per-host contract: supported Avalonia,
  7. Prove parity. Build the evidence bundle defined in
  8. Localize. Apply fieldworks-localization-review; field labels stay
  9. Retire and gate. Run the symbol audit
  10. Retrospective. Update these skills — see "Keep this skill set

What it can do on your machine

Read from SKILL.md and the folder at commit bd0608d. 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

Fieldworks Winforms To Avalonia Migration loads about 3.7k tokens when it runs, and up to ~25k if it reads all its reference files. Until then it costs about 161 tokens; SKILL.md has 1,752 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~161
When it runs · the whole SKILL.md, loaded when a task matches
~3.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~25k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,752 words (~3,730 tokens).

“This is the hub skill for the migration program. It tells you what architecture already exists (do not reinvent it), what order to work in, which companion skill to apply at each step, and how to keep this skill set…”
