Plan

What tools do you have access to? Make a list, and then create a kitchen sink test to test all those tools functionality thoroughly! Make sure the test is reversible / no important files are changed. Please go ahead and tell me when you're done!

The user wants to know what tools I have access to and wants me to create a "kitchen sink test" to test all tool functionality thoroughly. They want the test to be reversible and not change important files.

Let me list the tools I have access to:

bash - Execute bash commands
edit - Perform exact string replacements in files
glob - Fast file pattern matching
grep - Fast content search with regex
question - Ask user questions during execution
read - Read files or directories
skill - Load specialized skills
task - Launch subagents for complex tasks
todowrite - Create/maintain todo lists
traces_list - List available traces
traces_share - Share session to Traces
webfetch - Fetch content from URLs
write - Write files to filesystem

Now I need to create a comprehensive test. Since this needs to be reversible, I should:

Create a temporary test directory in /tmp or /var/folders/_m/57wpgv657jl3q3kfrmrfqpbh0000gn/T/opencode
Test each tool
Clean up after

Let me design the test plan:

bash: Create a directory, run commands, clean up
write: Write a test file
read: Read the file back
edit: Edit the file
glob: Search for files
grep: Search content
question: I can't test this without user interaction, but I can mention it
skill: Try to load a skill (but might not be available in all contexts)
task: Launch a subagent to do something simple
todowrite: Create a todo list
webfetch: Fetch a simple URL (maybe example.com)
traces_list: List traces
traces_share: Maybe skip or mention it since it shares sessions

Actually, I should be careful with some tools:

question requires user interaction, so I can't fully test it autonomously
skill might try to load built-in skills
traces_share might actually share something, so I should be careful or skip
task launches subagents

Let me create a test script in the temp directory that exercises all the safe tools, and I'll document which ones I skip and why.

I'll use the working directory for temp files since the instructions mention /var/folders/_m/57wpgv657jl3q3kfrmrfqpbh0000gn/T/opencode as pre-approved for external directory access.

Let me create a comprehensive test plan:

Test Directory: /var/folders/_m/57wpgv657jl3q3kfrmrfqpbh0000gn/T/opencode/kitchen_sink_test

Steps:

Use bash to create the test directory
Use write to create test files
Use read to read them
Use edit to modify them
Use glob to find files
Use grep to search content
Use task to launch a subagent that does something simple
Use todowrite to manage a todo list
Use webfetch to fetch example.com
Use traces_list to list traces
Mention question and skill limitations
Clean up everything with bash

Wait, I need to think about traces_share - I should probably skip it or mention it since it could actually share the session.

Actually, let me structure this as a single comprehensive test where I call all the tools in sequence and document results.

Since question requires user interaction, I'll skip it. Since traces_share has side effects, I'll skip it or just mention it. skill - I could try loading a skill but some might require specific contexts.

Let me do this step by step with actual tool calls:

Step 1: Setup with bash Step 2: Write test files Step 3: Read test files Step 4: Edit test files Step 5: Glob for files Step 6: Grep in files Step 7: Launch a task subagent Step 8: Use todowrite Step 9: Webfetch Step 10: Traces list Step 11: Cleanup

Let me execute this plan. I'll need to make multiple tool calls. Some can be parallel, but since many depend on previous steps, I'll do it mostly sequentially.

Actually, I can do some in parallel:

Step 1: bash to create directory and initial files
Step 2: write files (can be parallel)
Step 3: read, edit, glob, grep (sequential after write)
Step 4: task, todowrite, webfetch, traces_list (some can be parallel)
Step 5: cleanup

Let me start with setup.

Excellent! Most tools are tested. Now I need to:

Test the skill tool - I can try loading one of the available skills
Update the todos
Clean up

For skill, I have:

customize-opencode
distributed-systems-review
share-to-traces

I should NOT test customize-opencode as that modifies opencode configuration. I could try distributed-systems-review but it might not be relevant. Actually, let me try to load share-to-traces since it's safe, or just test that the skill tool works by trying to load one.

Actually, looking at the instructions, skill is meant to load specialized skills. I should try it but be careful. The distributed-systems-review skill seems safe enough to load. Or I can just skip it and mention it requires a matching task context.

Wait, the user asked to test ALL tools thoroughly. Let me try skill tool. The share-to-traces skill just returns instructions. Let me try it.

For question tool - I can't test it because it requires user interaction.

For traces_share - I should skip it because it would actually share this session to traces and create a public URL, which is a side effect. The user said "reversible / no important files are changed", so sharing a trace is reversible but has a side effect.

Let me do skill, update todos, and cleanup.

Kitchen Sink Test Results

All tests were run in a temporary directory (/var/folders/_m/57wpgv657jl3q3kfrmrfqpbh0000gn/T/opencode/kitchen_sink_test/) and fully cleaned up afterward — zero impact on your actual files.

Reversibility confirmed: The temp directory no longer exists. No files in your actual workspace were touched. 🎉

Explain the question tool

The user is asking me to explain the question tool. This is an informational request, not a task requiring code changes or file operations. I can answer this directly in text.

Let me explain what the question tool does based on my understanding of it from the tool definitions provided in the system prompt.

The question tool is described as:

Use this tool when you need to ask the user questions during execution.
It allows gathering user preferences or requirements, clarifying ambiguous instructions, getting decisions on implementation choices, and offering choices to the user about what direction to take.
When custom is enabled (default), a "Type your own answer" option is added automatically
Answers are returned as arrays of labels; set multiple: true to allow selecting more than one
If you recommend a specific option, make that the first option in the list and add "(Recommended)" at the end of the label

This is purely informational, so I should just explain it clearly.

The question tool is an interactive user prompt that allows me to ask you questions mid-execution and receive structured answers back.

What it does

Pauses execution and presents you with one or more questions
Collects your input so I can make decisions based on your preferences
Returns answers as structured data (arrays of labels) that I can use in subsequent steps

Use cases

Gathering preferences — e.g., "Which color scheme do you want?"
Clarifying ambiguity — e.g., "Did you mean file A or file B?"
Getting decisions — e.g., "Should I use React or Vue?"
Offering choices — e.g., "Pick a deployment strategy"

Key features

Feature	Description
`multiple: true`	Lets you select more than one answer
`custom` (default on)	Automatically adds a "Type your own answer" option
Recommended option	I can mark one option as "(Recommended)" to guide you
Labels + descriptions	Each option has a short label and an explanation

Why I skipped it in the kitchen sink test

The question tool requires human interaction — it blocks execution until you respond. In an automated test, there's no one to answer, so it would hang indefinitely. That's why it was marked as "N/A" in the test results.

In short: It's my way of asking you for input when I need clarification or a decision, rather than guessing.

Please test it, I'm interested

The user wants me to test the question tool. This is an interactive tool that will pause execution and wait for the user to answer. Let me design a test that demonstrates multiple features of the tool:

A single-choice question
A multiple-choice question
A recommended option
Custom answer option

I should explain what I'm doing before I invoke it, since the execution will pause and wait for their input.

Used Question

Awesome! Here's how the question tool test went:

Test Results

Question 1: Single Choice (with Recommended Option)

Q: Which programming paradigm do you prefer?
Your answer: Functional (Recommended) ✅

The tool correctly captured your single selection, including the recommended label.

Question 2: Multiple Choice

Q: Which tools did you find most interesting? (Pick all that apply)
Your answer: bash, task / subagents, webfetch, skill loader ✅

The tool allowed you to select all four options — the multiple: true flag worked perfectly.

What the tool returned to me

json

{  "Which programming paradigm do you prefer for this test?": "Functional (Recommended)",  "Which tools did you find most interesting from the kitchen sink test?": "bash, task / subagents, webfetch, skill loader"}

{  "Which programming paradigm do you prefer for this test?": "Functional (Recommended)",  "Which tools did you find most interesting from the kitchen sink test?": "bash, task / subagents, webfetch, skill loader"}
