- The test verifies that only 'owner' is required but doesn't verify that 'repo' is not in the required array. Consider adding an explicit assertion that 'repo' is not required to make the test more complete.

toolDef, _ := ListDiscussionCategories(stubGetGQLClientFn(mockClient), translations.NullTranslationHelper)
assert.Equal(t, "list_discussion_categories", toolDef.Name)

- Consider adding a test case where
repois explicitly set to an empty string to verify the behavior when the parameter is present but empty, as this might behave differently from when the parameter is completely omitted.

Overview
Closes: #818
This PR improves the existing
list_discussion_categoriestool, by adding logic to handle organisation-level discussions. (It implements similar logic to what I implemented in PR #775 )Changes introduced
Before, the "repo" argument was required, so when the user would ask to query org-level discussions the model would either (i) hallucinate random values for
repoor (ii) it would have to know the implementation detail about the Github API which is that org-level discussions are stored in a hidden.githubrepo.With these changes:
repoargument is made optionalrepoif discussions are to be queried at the org-levelrepovalue is deterministically set to.githubwhen neededBefore (the model hallucinates repo values)
After (the model correctly omits the repo argument, and the tool uses the deterministic flow to query org-level discussions)
