+Agent guidance for this repository (`Soul Droid Chat`).
+
+## Quick Start for New Agents
+
+1. Read `game/script.rpy`, `game/screens.rpy`, and `game/llm_ren.py` to understand flow and LLM integration.
+2. Run `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" lint` before making changes.
+3. Make small, focused edits that preserve Ren'Py ids and the `EMOTION:<value>` response contract.
+4. Validate with `compile` and `test` (`test <testcase_or_suite_name>` for a single case while iterating).
+5. Avoid committing generated artifacts/logs (`*.rpyc`, `game/cache/`, `log.txt`, `errors.txt`, `traceback.txt`) or secrets.
+6. In your handoff, include what changed, why, and exact validation commands run.
+
+## Project Snapshot
+
+- Engine: Ren'Py 8.5.x project with script files in `game/*.rpy`.
+- Python support code is embedded in Ren'Py files and `game/*_ren.py`.
+- Runtime dependency: LM Studio server (default `http://localhost:1234`).
+- No dedicated `tests/` directory was found; use Ren'Py `lint` and `test`.
+
+## Repository Layout
+
+- `game/script.rpy`: main dialogue/game flow loop.
+- `game/screens.rpy`: UI screens, preferences, and menus.
+- `game/options.rpy`: Ren'Py/build/runtime config and defaults.
+- `game/llm_ren.py`: LLM call logic, parsing, and sanitizing.
+- `game/constants_ren.py`: emotion synonym table.
+- `project.json`, `android.json`: distribution/build settings.
+
+## Tooling and Environment
+
+- Expected Ren'Py launcher script in PATH: `renpy.sh`.
+- CLI usage pattern:
+  - `"renpy.sh" "<repo-path>" <command> [args]`
+- Python in environment is available (`python3`), but gameplay validation should use Ren'Py commands.
+
+## Build, Lint, and Test Commands
+
+Run all commands from repository root:
+`/home/$USER/Documentos/Renpy Projects/Soul Droid Chat`
+
+### Quick checks (most common)
+
+- Lint project:
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" lint`
+- Run game locally:
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" run`
+- Compile scripts/python cache:
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" compile`
+
+### Test execution (Ren'Py test runner)
+
+- Run default/global test suite:
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" test`
+- Run a single test suite or testcase (important):
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" test <testcase_or_suite_name>`
+- Show detailed test report:
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" test --report-detailed`
+- Run all testcases even if disabled:
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" test --enable-all`
+
+### Distribution/build packaging
+
+- Create distributions (launcher command):
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" distribute`
+- Android build exists as a Ren'Py command (if SDK/keystore configured):
+  - `"renpy.sh" "/home/$USER/Documentos/Renpy Projects/Soul Droid Chat" android_build`
+
+## Suggested Validation Sequence for Agents
+
+1. `lint`
+2. `compile`
+3. `test` (or `test <single_case>` when iterating)
+4. `run` for a manual smoke check on the edited flow/screen
+
+If a command fails, include the failing command and key error excerpt in your report.
+
+## Code Style Guidelines
+
+### General principles
+
+- Match existing Ren'Py and Python style in nearby files.
+- Prefer small, focused changes; avoid unrelated refactors.
+- Keep user-facing narrative tone and Anita persona constraints intact.
+- Preserve ASCII-oriented output behavior where current code expects it.
+
+### Ren'Py script/style conventions (`.rpy`)
+
+- Use 4-space indentation; never tabs.
+- Keep labels/screen names `snake_case` (`label start`, `screen quick_menu`).
+- Keep style declarations grouped and readable (existing file order is a good template).
+- For dialogue flow, keep Python blocks short; move reusable logic to `*_ren.py`.
+- Use explicit keyword args when clarity helps (`prompt =`, `fadeout`, `fadein`).
+- Do not rename core ids required by Ren'Py (`_("window")`, `_("what")`, `_("who")`, `_("input")`).
+
+### Python conventions (`*_ren.py` and embedded `init python`)
+
+- Imports:
+  - Standard library first (`re`).
+  - Ren'Py modules (`renpy`, `persistent`).
+  - Local imports last (`from .constants_ren import SYNONYMS`).
+- Naming:
+  - Functions/variables: `snake_case`.
+  - Constants: `UPPER_SNAKE_CASE` (`EMOTIONS`, `SYSTEM_PROMPT`).
+  - Keep names descriptive (`parse_emotion`, `sanitize_speech`, `fetch_llm`).
+- Types:
+  - Add type hints on new/edited Python functions when practical.
+  - Keep return types accurate (for list-returning functions, annotate accordingly).
+- Formatting:
+  - Follow PEP 8 basics for spacing, line breaks, and readability.
+  - Keep multiline literals and dicts formatted consistently with existing file style.
+
+### Error handling and resilience
+
+- Wrap external boundary calls (network/LM Studio) with `try/except`.
+- Return safe fallback values that keep game loop stable.
+- Error messages should be concise and actionable for debugging.
+- Avoid swallowing exceptions silently; at minimum return or log context.
+- Preserve conversation continuity fields when present (`last_response_id`).
+
+### LLM integration constraints
+
+- Keep `SYSTEM_PROMPT` format guarantees consistent unless intentionally changing behavior.
+- Maintain `EMOTION:<value>` parsing contract used by dialogue rendering.
+- If you add emotions, update both:
+  - `EMOTIONS` in `game/llm_ren.py`
+  - `SYNONYMS` in `game/constants_ren.py`
+- Keep speech sanitization aligned with UI/rendering constraints.
+
+### UI/screens changes
+
+- Reuse existing `gui.*` variables and style helpers where possible.
+- Keep mobile/small variant handling (`renpy.variant(_("small"))`) intact.
+- Prefer extending existing screens over introducing parallel duplicate screens.
+- For settings UI, follow patterns already used in `preferences` screen.
+
+## Agent Working Rules
+
+- Before edits:
+  - Read related files fully (at least the touched blocks and nearby context).
+  - Check for existing patterns and follow them.
+- During edits:
+  - Do not include secrets or API keys in committed files.
+  - Do not commit generated caches/logs (`*.rpyc`, `log.txt`, `errors.txt`, `traceback.txt`).
+- After edits:
+  - Run relevant validation commands from the section above.
+  - Summarize what changed, why, and what was validated.
+
+## Git and Change Scope
+
+- Keep commits scoped to the requested task.
+- Avoid touching binary assets unless the task explicitly requires it.
+- If a keystore or credential-like file is changed, call it out explicitly.
+- Do not rewrite history unless explicitly requested.
+
+## Cursor/Copilot Rules Status
+
+- No repository-specific Cursor rules were found:
+  - `.cursor/rules/` not present.
+  - `.cursorrules` not present.
+- No repository-specific Copilot instruction file found:
+  - `.github/copilot-instructions.md` not present.
+
+If any of the above files are added later, treat them as higher-priority constraints and update this document.
