🤖 Auto-generated by Claude Opus 5 (claude-opus-5) via Claude Code — NOT human-reviewed. Verify before acting.
Verified against source and by executed tests in this repo. Not verified: behaviour on a live device with a real skill.

Fixes #556.

SkillResources supports user overrides under ~/.local/share/mycroft/resources/<skill_id>/, and ResourceFile._locate prefers them:

# resource_files.py
if self.resource_type.user_directory:
    walk_directory = str(self.resource_type.user_directory)

_load_dialog_renderer did not go through that path. It built its directory list from locate_lang_directories(self.language, self.skill_directory, "dialog"), and that function only ever searches what it is handed:

base_dirs = [Path(skill_directory, "locale")]
if resource_subdirectory:
    base_dirs.append(Path(skill_directory, resource_subdirectory))

user_directory was never consulted, so a .dialog override was written, kept, and never used — not immediately, and not after a restart either. .voc, .intent, .word, .list and .value all worked, because those go through ResourceFile. Only dialog was affected, and dialog is the one that decides what the device says.

The change

The renderer needs a directory of dialogs rather than a single file, so it cannot route through ResourceFile. The language-matching half of locate_lang_directories is now match_lang_directories(lang, base_dirs), and _load_dialog_renderer uses it to search the override directory first:

user_dir = self.types.dialog.user_directory
base_dirs = match_lang_directories(self.language, [user_dir] if user_dir else [])
base_dirs += locate_lang_directories(self.language, self.skill_directory, "dialog")

locate_lang_directories keeps its signature and behaviour; it now delegates its inner loop. Language matching, distance ordering and the lang_matches threshold are unchanged, so an override for the wrong language is skipped exactly as a skill directory for the wrong language is.

Tests

test_load_dialog_renderer was a # TODO: pass stub. It is now a real test, alongside two more:

  • the skill's own dialog renders when there is no override
  • a user override renders instead of the skill's own — fails on dev, passes here
  • an override for a different language is not used

Each uses its own skill id, because the class shares one XDG data directory between tests.

Unit suite: 604 passed, 2 skipped. Two failures in test/unittests/skills/test_intent_layers_e2e.py are pre-existing — I confirmed they fail identically on a clean dev checkout, and they are untouched by this diff. test_ask_e2e.py needs ovoscope, which is not declared as a test dependency; installing it lets that module collect.

Not covered

ResourceType.locate_user_directory sets user_directory only when the directory already exists, and runs once when SkillResources is constructed. An override directory created after a skill loaded is therefore still invisible until restart, for every resource type. That is a separate, smaller issue and not changed here.

Why it was noticed

ovos-control-panel has a Translate page whose purpose is letting someone correct or translate what their device says, by writing exactly these files. For .dialog the write succeeded, the page reported success, and the device kept saying the original words. The panel is carrying a caveat about it; with this merged it can drop it.

Summary by CodeRabbit

  • New Features

    • Added language-aware dialog resource matching, selecting the closest available language directories.
    • User-provided dialog overrides now take precedence over skill-provided dialogs.
  • Bug Fixes

    • Improved language isolation so dialog resources from unrelated languages are not selected.
  • Tests

    • Added coverage for skill dialogs, user overrides, language matching, and override precedence.

Every resource type prefers the user override directory: `ResourceFile._locate`
walks it before the skill's own files, so a translation written there changes
what a skill hears. Dialog is what a skill says, and it was the one type that
never looked. `_load_dialog_renderer` built its directory list straight from
`locate_lang_directories`, which only ever searches the skill directory, so an
override was written, kept, and never used -- not immediately, and not after a
restart either.

The renderer needs a directory rather than a single file, so it cannot go
through ResourceFile. The language-matching half of `locate_lang_directories` is
now its own function, and the renderer uses it to search the override directory
before falling back to the skill's.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds centralized language-directory matching and applies user dialog overrides before skill dialog resources. Tests cover normal rendering, same-language override precedence, and isolation from other-language overrides.

Changes

Dialog Override Resolution

Layer / File(s) Summary
Language directory matching
ovos_workshop/resource_files.py
match_lang_directories finds existing language directories and sorts them by language distance. locate_lang_directories uses the new helper.
Dialog loading and validation
ovos_workshop/resource_files.py, test/unittests/test_resource_files.py
SkillResources._load_dialog_renderer checks user dialog directories before skill directories. Tests create localized resources and verify override precedence and language isolation.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 27cd6

A partial user dialog override can hide dialog files that exist only in the skill, causing some prompts to fall back to unresolved keys instead of producing the intended speech. The PR should be updated to merge user and skill dialog files before merge.

The changes satisfy issue #556 by adding the user dialog override directory before skill dialog directories and adding tests for overrides and language isolation. The separate post-initialization directory limitation is explicitly outside this PR's scope.

687-697: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift

Merge dialog files at file level.

SkillResources._load_dialog_renderer passes only the first existing matching directory to ovos_utils.dialog.load_dialogs and then returns. load_dialogs walks only that directory. A user directory containing only hello.dialog therefore prevents the skill directory's goodbye.dialog from loading. MustacheDialogRenderer.render("goodbye") returns goodbye.

Load the skill dialogs first, then apply user files with matching names. Add a regression test with one overridden dialog and one skill-only dialog.
