+
+Notes:
+- `--tags` is preferred for targeted runs once tasks are tagged consistently.
+- Today, `site.yml` actively applies `dotfiles_common`, `packages_void`, `services_runit`, and `profile_desktop_i3`.
+- Dependencies: Python 3, Ansible, and host access (local or SSH depending on inventory).
+- Setup: `python3 -m pip install ansible` (plus optional `ansible-lint yamllint`).

 ## Code style guidelines
 
-### General principles
-- Keep changes idempotent and declarative.
-- Preserve layering: `common -> OS -> profile -> host`.
-- Avoid unrelated refactors; keep edits minimal and local.
+### Core principles
+- Keep automation idempotent, declarative, and host-safe.
+- Preserve variable layering: `all -> OS -> profile -> host`.
+- Keep edits minimal and local; avoid opportunistic refactors.
+- Prefer readability over compression in YAML/Jinja.
 
-### Ansible modules, imports, and structure
-- Use FQCN module names (`ansible.builtin.copy`, `community.general.xbps`).
-- Prefer modules over raw `shell`/`command`.
-- Use `import_tasks`/`include_tasks` when role task files grow.
-- Keep `site.yml` orchestration-focused; implementation lives in roles.
-- Keep role scope narrow (packages vs services vs dotfiles).
+### Modules, imports, and role structure
+- Use FQCN modules (`ansible.builtin.copy`, `community.general.xbps`).
+- Prefer modules over `ansible.builtin.shell`/`ansible.builtin.command`.
+- If command/shell is necessary, document intent via task name and guards.
+- Keep `ansible/site.yml` orchestration-focused; implementation belongs in roles.
+- Split large role task files with `import_tasks`/`include_tasks`.
+- Keep each role narrow in purpose (packages, services, profile, dotfiles).
 
-### Formatting
+### YAML formatting
 - Start YAML files with `---`.
-- Use 2-space indentation; never tabs in YAML.
-- Quote modes as strings: `"0644"`, `"0755"`, `"0600"`.
-- Keep long Jinja expressions multiline and readable.
-- No trailing whitespace.
+- Use 2-space indentation, never tabs.
+- Keep key ordering stable and meaningful.
+- Quote file modes as strings: `"0644"`, `"0755"`, `"0600"`, `"0700"`.
+- Keep long Jinja expressions multiline.
+- Avoid trailing whitespace.
 
 ### Variables and types
 - Use `snake_case` variable names.
-- Keep names semantically scoped (`common_packages`, `profile_packages`, `host_packages`).
-- Use true YAML types: lists for lists, booleans as `true`/`false`.
-- Use `default([])` / `default({})` for optional vars.
-- Keep paths consistent, usually templated from `{{ user_home }}`.
-- Put global defaults in `group_vars/all.yml`; specialize in group/host vars.
+- Use semantically scoped names (`common_packages`, `void_packages_base`, `host_packages`).
+- Keep booleans as `true`/`false`, not quoted strings.
+- Keep lists and dicts as real YAML collections.
+- Use `default([])` / `default({})` for optional variables.
+- Build paths consistently from `{{ user_home }}` and related vars.
+- Put shared defaults in `group_vars/all.yml`; specialize in group/host vars.
 
 ### Naming conventions
-- Roles: lowercase with underscores.
-- Tasks: imperative, explicit outcome (`Install packages on Void Linux`).
-- Inventory group and var file names must stay aligned.
-- Host var files should match hostnames exactly.
+- Role directories: lowercase with underscores.
+- Task names: imperative and outcome-based (`Enable host runit services`).
+- Inventory group names and matching var filenames should stay aligned.
+- Host var filenames must match hostnames exactly.
 
 ### Error handling and safety
-- Guard OS/profile-specific actions with `when`.
-- For `command`/`shell`, set `changed_when`/`failed_when` where needed.
-- Do not suppress failures without clear justification.
-- Validate risky changes with `--check --diff` before real apply.
-- Avoid destructive user-file operations unless explicitly required.
+- Guard OS/profile-specific steps with `when`.
+- Use explicit `loop` inputs and default guards for optional lists.
+- For `command`/`shell`, define `changed_when` and `failed_when` when needed.
+- Do not suppress failures unless there is a clear operational reason.
+- Validate risky changes with `--check --diff` before full apply.
+- Avoid destructive file operations in user homes unless explicitly required.
+- Avoid touching secrets material; never commit credentials.
 
-### Shell and dotfiles
-- Prefer POSIX `sh` unless Bash features are required.
-- If Bash is required, use `#!/usr/bin/env bash`.
-- Quote expansions (`"$var"`) unless intentional word splitting is required.
-- Keep automation-invoked scripts non-interactive.
+### Dotfiles and shell scripts
+- Prefer POSIX `sh`; use Bash only when required.
+- If Bash is required, use shebang `#!/usr/bin/env bash`.
+- Quote expansions (`"$var"`) unless intentional splitting is required.
+- Keep scripts non-interactive when invoked by automation.
 
-## Agent operating expectations
-- Never commit or expose data from `secrets/`.
+## Agent expectations
 - Do not modify unrelated files.
-- Keep docs (`README.md`, `AGENTS.md`) current when workflows change.
-- If adding new task domains, add tags to improve targeted runs.
+- Never commit or expose data from `secrets/`.
+- Keep `AGENTS.md` and `README.md` in sync with workflow changes.
+- When adding new role domains, add tags to support targeted execution.
