What it does

Go Testing is an agent skill from Gentleman-Programming/gentle-ai. Trigger: Go tests, go test coverage, Bubbletea teatest, golden files. Apply focused Go testing patterns.

Its SKILL.md is about 550 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/examples.md`).

It sits in Testing & QA, covering Test coverage and Test strategy. The repository describes itself as: Gentle-AI configures the AI coding agents you already use: Claude Code, Cursor, OpenCode, Codex, Pi, and more. Choose persistent memory, Organic-Driven Development, curated… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Test coverage
  • Tasks that involve Test strategy

Example prompts

  • “/go-testing”

Workflow steps

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

  1. Identify behavior under test and the smallest public boundary that proves it.
  2. Choose the test pattern from the decision gate.
  3. Name cases by scenario, not input mechanics.
  4. Assert outputs, errors, state, and side effects explicitly.
  5. Run the narrow package test first, then the relevant broader suite.
  6. For golden updates: run with -update, inspect diff, then rerun without -update.

What it can do on your machine

Read from SKILL.md and the folder at commit 81d2225. 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

Go Testing loads about 550 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 29 tokens; SKILL.md has 250 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~29
When it runs · the whole SKILL.md, loaded when a task matches
~550
With references · SKILL.md plus every file in references/, read only if the agent opens them
~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.

Activation Contract

Load this skill when writing or reviewing Go tests, adding coverage, testing Bubbletea/TUI flows, using teatest, or updating golden files.

Hard Rules

  • Prefer table-driven tests for multiple cases; use t.Run(tt.name, ...).
  • Test behavior and state transitions, not implementation trivia.
  • Use t.TempDir() for filesystem tests; never rely on a real home directory.
  • Keep integration tests skippable with testing.Short() when they run external commands or slow flows.
  • For Bubbletea, test Model.Update() directly for state changes; use teatest only for interactive flows.
  • Golden files must be deterministic; update only through the repo's -update path and rerun tests without -update.
  • Use small mocks/interfaces around system or command execution boundaries.

Decision Gates

TargetTest pattern
Pure function or parserTable-driven unit test.
Error behaviorExplicit success and failure cases.
File operationst.TempDir() plus focused assertions.
TUI state transitionDirect Model.Update() call with tea.Msg.
Full TUI interactionteatest.NewTestModel().
Rendered outputGolden file test.
Real external commandIntegration test; skip in -short.

Execution Steps

  1. Identify behavior under test and the smallest public boundary that proves it.
  2. Choose the test pattern from the decision gate.
  3. Name cases by scenario, not input mechanics.
  4. Assert outputs, errors, state, and side effects explicitly.
  5. Run the narrow package test first, then the relevant broader suite.
  6. For golden updates: run with -update, inspect diff, then rerun without -update.

Output Contract

Report test files changed, scenarios covered, commands executed, golden files updated, and any skipped integration scope.

Can I use Go Testing 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 Gentleman-Programming/gentle-ai --skill go-testing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/go-testing, .gemini/skills/go-testing, .github/skills/go-testing and .opencode/skills/go-testing in your project.

What does Go Testing need to run?

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

Does Go Testing access the network?
