What it does

UI Action is an agent skill from microsoft/copilot-for-eclipse, published by the product's own GitHub organization. Authors and validates SWTBot JSON probe scripts for GitHub Copilot for Eclipse UI flows against a real Eclipse workbench. Use when creating or updating probe-scripts, converting test plans to UI probes, validating end-to-end Eclipse UI behavior, or troubleshooting ProbeRunner failures.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `REFERENCE.md`).

It sits in Testing & QA, covering Test generation. The repository describes itself as: GitHub Copilot plugin for Eclipse IDE. The licence is MIT.

Workflow steps

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

Create one focused JSON script at
Start by settling the workbench and opening the view under test
Add user-level steps only, such as click, typeIn, clearElement, pressKey,
Run from the repository root
Read com.microsoft.copilot.eclipse.swtbot.test/target/probe-results/results.json,

What it can do on your machine

Read from SKILL.md and the folder at commit 00733c2. 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 json and bash).
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

UI Action loads about 1.1k tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 323 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~74
When it runs · the whole SKILL.md, loaded when a task matches: ~1.1k

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

The full file from microsoft/copilot-for-eclipse at commit 00733c2, republished under its MIT licence (© microsoft). 323 words, ~1,066 tokens.

description: Authors and validates SWTBot JSON probe scripts for GitHub Copilot for Eclipse UI flows against a real Eclipse workbench. Use when creating or updating probe-scripts, converting test plans to UI probes, validating end-to-end Eclipse UI behavior, or troubleshooting ProbeRunner failures.

SWTBot Probe Scripts

Use this skill to create or update JSON probes for com.microsoft.copilot.eclipse.swtbot.test. Probes drive the workbench through SWTBot actions and run as Tycho tests; no Java is compiled per test case.

Quick start

Create one focused JSON script at com.microsoft.copilot.eclipse.swtbot.test/probe-scripts/<plan-slug>-<tc-id>.json.

Start by settling the workbench and opening the view under test:

json

[
  { "action": "waitForIdle" },
  { "action": "screenshot", "id": "01-startup" },
  { "action": "showView", "idRef": "com.microsoft.copilot.eclipse.ui.chat.ChatView" },
  { "action": "waitForIdle" },
  { "action": "screenshot", "id": "02-chat-open" }
]

Add user-level steps only, such as click, typeIn, clearElement, pressKey, invokeCommand, waitFor, waitForMethod, assertExists, screenshot, or dumpUi. Prefer widgetId locators for widgets the plugin owns.
Run from the repository root:
bash
```
./mvnw clean verify -Dprobe.script=probe-scripts/<name>.json
```
Use root clean verify as the default. Tycho can reuse stale bundle jars when only the SWTBot module is run, making source edits appear ignored. Use xvfb-run -a on Linux headless.
Read com.microsoft.copilot.eclipse.swtbot.test/target/probe-results/results.json, workspace.log, screenshots/, and ui-dumps/.

If -Dprobe.script is unset, ProbeRunner skips itself so ordinary ./mvnw verify runs are unaffected.

Authoring workflow

Convert one scenario/test case into one probe. Split unrelated behaviors so each failure screenshot has one meaning.
Drive the UI the way a user does. invokeCommand is allowed for registered Eclipse command IDs; do not call OSGi services, private methods, or test-only shortcuts.
Pair screenshots with machine-checked assertions. Screenshots never fail a step; assertExists, waitFor, and waitForMethod decide pass/fail.
Wait for asynchronous UI state before acting. For chat, wait for the model-picker selected model before Send, then wait for user-turn and model-info-label.
When a locator fails, insert dumpUi before the failure and inspect ui-dumps/*.xml for widget class names and SWTBot widget IDs.
For unauthenticated chat probes, assert the "Sign in to GitHub" UI. Do not poll internal auth managers.

Chat send skeleton

json

[
  { "action": "waitForIdle" },
  { "action": "showView", "idRef": "com.microsoft.copilot.eclipse.ui.chat.ChatView" },
  { "action": "waitFor", "locator": { "by": "styledText" }, "timeoutSec": 30 },
  { "action": "clearElement", "locator": { "by": "styledText" } },
  { "action": "typeIn", "locator": { "by": "styledText" }, "text": "hello" },
  { "action": "waitForMethod", "locator": { "by": "widgetId", "value": "model-picker" },
    "method": "getSelectedItemId", "timeoutSec": 60 },
  { "action": "click", "locator": { "by": "buttonWithTooltip", "tooltip": "Send" } },
  { "action": "waitFor", "locator": { "by": "widgetId", "value": "user-turn" }, "timeoutSec": 30 },
  { "action": "waitFor", "locator": { "by": "cssClass", "value": "model-info-label" }, "timeoutSec": 120 },
  { "action": "assertExists", "locator": { "by": "widgetId", "value": "copilot-turn" } },
  { "action": "screenshot", "id": "agent-response" }
]

Pass/fail judgment

A probe passes only when Maven exits 0 and results.json has "failed": 0. On failure, inspect the failed step message, FAILED-stepNN-*.png, nearest ui-dumps/*.xml, and workspace.log.

Extending probes

The vocabulary lives in com.microsoft.copilot.eclipse.swtbot.test/src/.../probe/. Add UI-level primitives in ProbeStep, Locator, and StepExecutor, then update REFERENCE.md.

See REFERENCE.md for action/locator tables, platform notes, result queries, troubleshooting, and current stable widget IDs.

Can I use UI Action in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add microsoft/copilot-for-eclipse --skill ui-action -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ui-action, .gemini/skills/ui-action, .github/skills/ui-action and .opencode/skills/ui-action in your project.

What does UI Action need to run?

SKILL.md names no scripts, command-line tools or credentials: UI Action is instructions for the agent only.

Does UI Action access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is UI Action safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does UI Action use?

UI Action is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does UI Action use?

About 1.1k tokens (SKILL.md is roughly 4.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
