test(kit): Add test for GetToolsForSubagent()

[e4t]

GetToolsForSubagent() was added in commit:
Make subagent inherit tools from parent (#51)
ef072f6
to collect all tools from the main agent but exclude the 'subagent' tool. The resulting tool list may be passed to the Tools argument of SubagentConfig.

The test works as follows:

1. The main 'kit' instance is configured with a CoreToolList only containing 'subagent' and 'bash'.
2. A 'hello' tool is provided as ExtraTools in kit.Options. In this case, the main 'kit' instance will only have the 'subagent', 'bash' and 'hello' tool. GetToolsForSubagent() should filter out the 'subagent' tool. GetToolsForSubagent() is called and the result is checked against the expected list.

Summary by CodeRabbit

• Tests
  • Added coverage to ensure subagent tool availability behaves correctly when core tools are disabled.
  • Verified that subagent does not include the core subagent tool, while still exposing both custom extra tools and remaining allowed core tools.

📝 Walkthrough

Walkthrough

Adds a new test for GetToolsForSubagent in pkg/kit/kit_test.go. The test builds a custom tool, configures core and extra tools, and verifies the returned list includes the expected tools and excludes subagent.

Poem

🐇 Hello hops in with a carrot and grin,
Bash tags along while subagent stays thin.
The tool list is tidy, the test gives a cheer,
A small bunny check for the right tools here.

In `@pkg/kit/kit_test.go`:
- Around line 675-676: The HelloInput.Query struct field in kit_test.go uses a
non-standard JSON tag, so update its tag to follow the repository’s snake_case
convention and keep the schema key consistent; locate the Query field in
HelloInput and change the json tag to a snake_case name, using omitempty if that
field is optional.
- Around line 695-711: The subagent test is asserting model prose in
result.Response instead of the actual tool selection, so update the test around
host.Subagent and host.GetToolsForSubagent() to directly inspect the returned
tool set and verify the expected tools are present or absent. Use the
SubagentConfig setup as-is, but replace the “hello”/“subagent” string checks
with assertions on the tool list/filtering behavior so the test validates
GetToolsForSubagent() deterministically.

The linter issues seen in the CI are false positives and not related to the changes I've submitted:

  Error: internal/models/custom_test.go:23:6: SA5011(related information): this check suggests that the pointer can be nil (staticcheck)
  		if p == nil {
  		   ^
  Error: internal/models/custom_test.go:26:8: SA5011: possible nil pointer dereference (staticcheck)
  		if p.Temperature == nil || *p.Temperature != 0.7 {
  		     ^

apparently, the linter doesn't recognize that a call to test.Fatal() does not return. I cannot reproduce these locally so I'm unsure on how exactly to 'whitelist' then.
