+# Code Cleanup Command
+
+## Overview
+Analyze git diff between the specified branch and HEAD (defaults to main if no branch specified) and clean up code quality issues without altering functionality.
+
+## Process
+1. **Get diff**: Run `git diff <branch>..HEAD` to see changes
+2. **Identify issues**: Look for code quality problems in the diff
+3. **Clean up**: Remove only the identified issues
+4. **Verify**: Ensure no behavioral changes
+
+## What to Clean Up
+- **Debug artifacts**: `console.log()`, `debugger`, `print()` statements
+- **Unused code**: Variables, imports, functions, parameters
+- **Commented code**: Dead code blocks, TODO comments (unless active)
+- **Formatting**: Inconsistent spacing, trailing whitespace
+- **Temporary code**: Test values, hardcoded strings meant to be dynamic
+- **Redundant code**: Duplicate logic, unnecessary intermediate variables
+
+## What NOT to Touch
+- **Functional logic**: Don't change how features work
+- **API interfaces**: Keep method signatures intact
+- **Configuration**: Don't modify settings or constants
+- **Comments**: Keep documentation and explanatory comments
+- **Error handling**: Don't remove try-catch blocks or validation
+
+## Safety Rules
+- ✅ Only modify code that appears in the git diff
+- ✅ Preserve all existing functionality
+- ✅ Maintain code readability and structure
+- ❌ Don't refactor or optimize beyond cleanup
+- ❌ Don't add new features or improvements
+- ❌ Don't change variable names or function signatures
+
+## Example
+```bash
+# If user specifies: "/clean-up main"
+git diff main
+# Clean only the issues found in this diff
+```

+# Security Audit Command
+
+Perform a comprehensive security audit of the FromChat **Android application** only.
+
+## Project Context
+
+**FromChat Android** is a 100% open source secure messaging mobile application built with:
+
+- Kotlin Multiplatform (KMP) shared code
+- Jetpack Compose UI framework
+- End-to-End Encryption (NaCl, AES-GCM)
+- WebSocket support for real-time features
+- LiveKit integration for calls
+- Local database storage (SQLite)
+
+## Scope: Android Only
+
+**OUT OF SCOPE:**
+
+- Web backend (Python FastAPI, Caddy infrastructure)
+- React/TypeScript frontend
+
+**IN SCOPE:**
+
+- Android app code (`app/android`, `app/shared/src/androidMain`)
+- Shared cross-platform code (`app/shared/src/commonMain`)
+- Local encryption implementation (NaCl, AES-GCM)
+- Secure storage (Android Keystore, encrypted SharedPreferences)
+- WebSocket client security
+- Permission usage and handling
+- Call security (LiveKit integration)
+- Memory safety and injection attacks
+- Backend
+
+## Important Design Decisions (NOT Vulnerabilities)
+
+When auditing, remember these are **intentional design choices**:
+
+1. **Local message caching** - Messages downloaded and stored locally (by design)
+  - Messages are end-to-end encrypted at rest in local DB
+  - Public DMs are not encrypted (messages are public)
+  - Private DMs use NaCl encryption
+  - Cache persists across app restarts for offline access
+2. **Local key storage** - Encryption keys stored on device (by design)
+  - Keys protected by Android Keystore (hardware-backed when available)
+  - Encrypted with device-specific secrets
+  - User data never leaves device in plaintext
+  - Do NOT flag key storage as critical (Keystore is production-ready)
+
+## Output Format
+
+Provide a **clean, concise report** with:
+
+1. **Executive Summary** - Overall rating and production readiness
+2. **Security Status** - Critical issues (if any) and recommendations
+3. **Security Strengths** - What's done well
+4. **Component Ratings** - Table format for quick reference
+5. **Architecture Review** - Data flow, encryption boundaries
+6. **Threat Analysis** - Current realistic threats (e.g., rooted device, malicious APK)
+7. **Recommendations** - Prioritized with time estimates
+8. **Conclusion** - Clear production readiness statement
+
+**Keep it under 500 lines** - focus on actionable findings, not verbose explanations.
+
+## Common False Positives to Avoid
+
+❌ **DO NOT FLAG THESE AS ISSUES:**
+
+- Local message caching (intentional for offline access)
+- Public message viewing without auth (intentional design)
+- Debuggable APK (only relevant if signed/released)
+

+Please analyze the recent commits in this repository and help me clean up the commit history. I want you to:
+
+1. First, show me all commits between the target ref and HEAD using: `git log --oneline <base-branch>..HEAD`
+2. Identify which commits should be squashed together (like cleanup commits, small fixes, or related changes)
+3. For each group of commits you plan to squash, read their full details using: `git show <commit-hash>` to understand what changes they contain
+4. Create a git-rebase-todo.txt file with your recommended rebase plan
+5. Explain your reasoning for the squashing decisions, including what changes each squashed group contains. Be concise.
+6. Stop and ask me if i agree with your plan.
+7. Then execute the rebase using these exact commands (replace `<base-branch>` with the target branch/ref):
+   ```bash
+   export GIT_SEQUENCE_EDITOR="cp git-rebase-todo.txt"
+   git rebase -i <base-branch>
+   ```
+8. If there are conflicts, stop and ask me to fix them.
+9. Delete the `git-rebase-todo.txt` file you created.s
+
+**Usage:** You can specify a target branch/ref as an argument. If no argument is provided, stop and ask me for the branch or ref to rebase onto.
+
+Focus on:
+- Squashing small cleanup commits into their related feature commits
+- Combining related bug fixes
+- Keeping meaningful feature commits separate
+- Maintaining a clean, logical commit history
+
+Please be conservative - if you're unsure about squashing something, ask me for clarification.

@@ -4,17 +4,63 @@ alwaysApply: true
 
 When working with this project, follow these rules:
 
+## Core Behavior
 - NEVER do anything i didn't ask you for!
-- Use double quotes ("") for strings.
+- Don't talk like a robot. Behave more like a human.
+- Be concise and direct in responses.
+- If you're unsure about something, ask for clarification instead of guessing.
+
+## Code Quality & Principles
+- Follow DRY, SOLID, YAGNI and KISS principles.
+- Do NOT use old, outdated or deprecated APIs and functions.
+- Use double quotes ("") for strings consistently.
+- Prefer functional components over class components in React.
+- Use TypeScript strictly - avoid `any` types unless absolutely necessary.
+- DO NOT leave placeholders - ask me when it would be better or implement it fully.
+
+## File Operations
+- If possible, try to update files in a single edit when making multiple changes.
+- Do NOT "cd" to the project directory.
+- NEVER edit/delete/regenerate .env files without explicit permission.
+- Don't use rg, it doesn't work anyway.
+
+## Testing & Validation
 - Do NOT "test the implementation" when you are done. The only exception is when you 
   need to typecheck or build the app, in that case:
-
   - To typecheck, run `npm run frontend:typecheck`.
   - To build, run `npm run frontend:build`.
+- Do NOT execute other commands like "cd".
+- If the typecheck passed, there's no need for checking the linter errors.
 
-  Do NOT execute other commands like "cd".
-- Do NOT "cd" to the project directory.
-- If possible, try to update files in a single edit.
-- When you need a delay, use `await delay(millis);` in an async function. If the current function is not async,
-  make it async. The import is `<project>/frontend/src/utils/utils`.
-- When you complete your task, remove unused imports if there are any.
+## Async Operations
+- When you need a delay, use `await delay(millis);` from `@/utils/utils` in an async function. If the current function is not async, make it async.
+
+## Database
+- NEVER create database migrations, they are auto-generated.
+
+## Project Structure Awareness
+- This is a React/TypeScript browser frontend (desktop is Compose Multiplatform in the Android/KMP repo)
+- Uses MDUI components for UI
+- Uses Zustand for state management
+- Uses use-immer for immutable state updates
+- Uses React Router for navigation
+- Has WebSocket support for real-time features
+- Uses encryption (tweetnacl) for security
+
+## Performance & Efficiency
+- Batch tool calls when possible to reduce latency
+- Use semantic search before grep when looking for concepts
+- Use TODOs for complex multi-step tasks to track progress
+
+## Styling
+- Use SCSS modules
+- Use nested styles
+- Put SCSS into one folder per page
+
+## Animations with Framer Motion
+- Don't use variants if they are used only once  
+
+## Debug Mode
+- When in debug mode and the issue is not yet fixed, ALWAYS end responses with `<reproduction_steps>` containing the steps to reproduce the issue and trigger logging
+- When NOT in debug mode or when the issue IS fixed, escape the tag as `&lt;reproduction_steps&gt;` to avoid triggering it
+- Never use other `<re>` tags, only `<reproduction_steps>`

+description: Decrypts a DM message on localhost by granting temporary compliance extract access, running extract and decrypt CLI commands, then reverting all temporary changes. Use when the user asks to decrypt a message or run the compliance decryption workflow on localhost.
+---
+
+# Decrypt (local debug)
+
+End-to-end workflow for extracting and decrypting one message on **localhost**. All temporary backend access must be removed when finished.
+
+**After decrypt:** what to do with the plaintext and files (compare, inspect, report, etc.) comes from the **current conversation** — not from this skill.
+
+## Prerequisites
+
+- Web dev server running at `http://localhost:8301` (browser rules default).
+- `compliance_keypair.txt` at the Web repo root (`Web/compliance_keypair.txt`).
+- Python deps for `scripts/compliance/decryption/` (`cryptography`, etc.).
+
+## Step 0 — Read the compliance keypair
+
+Read `Web/compliance_keypair.txt` before any decrypt step. Confirm the **private** key line exists (line after `PRIVATE KEY` header, base64).
+
+The decrypt CLI loads `compliance_keypair.txt` from the **current working directory**. Always run extract/decrypt with `cd` to the Web repo root:
+
+```bash
+cd /path/to/Web
+```
+
+If `load_compliance_private_key` fails, the file format may need a `PRIVATE_KEY=<base64>` line (the loader expects that or a 43-char base64 line; 32-byte keys are often 44 chars with padding).
+
+## Step 1 — Create a temporary user and capture token
+
+Generate random credentials (username 3–20 chars: letters, digits, `-`, `_`; password 5–50 chars, no spaces):
+
+```bash
+DEBUG_USER="decryptdbg$(openssl rand -hex 3)"
+DEBUG_PASS="$(openssl rand -base64 12 | tr -d '/+=' | head -c 16)"
+echo "user=$DEBUG_USER pass=$DEBUG_PASS"
+```
+
+Register and save **`token`** from the JSON response (not the derived login secret):
+
+```bash
+REGISTER_JSON=$(curl -sS -X POST "http://localhost:8301/api/register" \
+  -H "Content-Type: application/json" \
+  -d "{\"username\":\"${DEBUG_USER}\",\"display_name\":\"DecryptDebug\",\"password\":\"${DEBUG_PASS}\",\"confirm_password\":\"${DEBUG_PASS}\"}")
+echo "$REGISTER_JSON"
+DEBUG_TOKEN=$(python3 -c 'import json,sys; print(json.load(sys.stdin)["token"])' <<< "$REGISTER_JSON")
+echo "token saved (length ${#DEBUG_TOKEN})"
+```
+
+Alternatively export for the CLI: `export FROMCHAT_API_TOKEN="${DEBUG_TOKEN}"`
+
+Save `user.id` from the same JSON if needed for debugging.
+
+## Step 2 — Temporary compliance extract permission (marker blocks)
+
+`GET /api/dm/compliance/extract/{message_id}` is restricted to **user id 1** in:
+
+`backend/services/main/routes/envelope_messaging.py` (function `extract_message_for_compliance`).
+
+Add a **temporary** bypass between searchable markers (replace `DEBUG_USERNAME` with the user from step 1):
+
+```python
+    # TEMP_COMPLIANCE_DEBUG_START — remove after decrypt debug run
+    _TEMP_COMPLIANCE_DEBUG_USERNAMES = {"DEBUG_USERNAME"}
+    # TEMP_COMPLIANCE_DEBUG_END
+
+    # Security check: only user ID 1 can access this
+    if current_user.id != 1 and current_user.username not in _TEMP_COMPLIANCE_DEBUG_USERNAMES:
+```
+
+Backend will auto-reload after this change, you don't need to do anything.
+
+To remove later: search the repo for `TEMP_COMPLIANCE_DEBUG` and delete the marker block + revert the `if` to only `current_user.id != 1`.
+
+## Step 3 — Extract bundle (online)
+
+From Web repo root, set variables and run (user supplies `MESSAGE_ID`):
+
+```bash
+MESSAGE_ID=<message_id>
+RANDOM_FOLDER="run_$(openssl rand -hex 4)"
+BUNDLE_DIR="/tmp/debug_decrypt/${RANDOM_FOLDER}"
+DECRYPT_DIR="/tmp/debug_decrypt/${RANDOM_FOLDER}_dec"
+mkdir -p /tmp/debug_decrypt
+
+cd /path/to/Web
+python scripts/compliance/decryption/main.py extract \
+  --server localhost:8301 \
+  --http \
+  --token "${DEBUG_TOKEN}" \
+  --message-ids "${MESSAGE_ID}" \
+  --out-dir "${BUNDLE_DIR}"
+```
+
+Equivalent using env (no `--token` flag):
+
+```bash
+export FROMCHAT_API_TOKEN="${DEBUG_TOKEN}"
+python scripts/compliance/decryption/main.py extract \
+  --server localhost:8301 \
+  --http \
+  --message-ids "${MESSAGE_ID}" \
+  --out-dir "${BUNDLE_DIR}"
+```
+
+Confirm `${BUNDLE_DIR}/bundle.json` exists.
+
+**Auth flags:** use `--token` (Bearer from register/login), or `--username` + `--password` (CLI derives the login secret). Do not pass both.
+
+## Step 4 — Decrypt bundle (offline)
+
+Still from Web repo root (`compliance_keypair.txt` must resolve):
+
+```bash
+python scripts/compliance/decryption/main.py decrypt \
+  --bundle-dir "${BUNDLE_DIR}" \
+  --output-dir "${DECRYPT_DIR}"
+```
+
+Outputs:
+
+- `${DECRYPT_DIR}/messages/<message_id>/message.decrypted.txt` — message plaintext
+- `${DECRYPT_DIR}/messages/<message_id>/files/` — decrypted attachments
+- `${DECRYPT_DIR}/index.html` — HTML report
+
+## Step 5 — Use decrypted output (conversation-driven)
+
+Follow the **user’s request in the current chat** for what to do next (e.g. compare hashes, inspect text, verify a specific attachment). This skill stops at producing `${DECRYPT_DIR}`; do not assume a fixed post-decrypt task.
+
+## Step 6 — Cleanup (required)
+
+1. **Remove decrypt dirs:**
+   ```bash
+   rm -rf "${BUNDLE_DIR}" "${DECRYPT_DIR}"
+   ```
+
+2. **Delete temp user** (local SQLite default DB):
+   ```bash
+   sqlite3 backend/data/database.db "DELETE FROM users WHERE username='${DEBUG_USER}';"
+   ```
+   If your deployment uses another DB, delete the same username there.         
+
+3. **Remove temporary permission:** search `TEMP_COMPLIANCE_DEBUG` in the repo, delete the marker block, restore the original `if current_user.id != 1:` check, restart backend.                                  
+
+4. Do **not** commit `compliance_keypair.txt` or any decrypt output.
+
+## Checklist
+
+```
+- [ ] Read compliance_keypair.txt
+- [ ] Register DEBUG_USER; save DEBUG_TOKEN from response
+- [ ] Add TEMP_COMPLIANCE_DEBUG_* bypass; restart backend
+- [ ] extract --token → bundle.json present
+- [ ] decrypt → output under DECRYPT_DIR
+- [ ] Post-decrypt work per conversation context
+- [ ] rm -rf BUNDLE_DIR and DECRYPT_DIR
+- [ ] DELETE temp user from DB
+- [ ] Remove TEMP_COMPLIANCE_DEBUG markers; restart backend
+```
+
+## Reference
+
+- Extract API: `GET /api/dm/compliance/extract/{message_id}` (see `bundle_extract.py`).
+- Decrypt implementation: `scripts/compliance/decryption/bundle_decrypt.py`, `crypto.py`.
+- Extract auth: `--token` (Bearer), env `FROMCHAT_API_TOKEN` / `FROMCHAT_TOKEN`, or `--username` + plain `--password` (CLI calls `derive_auth_secret` for login only).
+
+## Rules
+- NEVER use sleep in any command.
+- Set a timeout on EVERY command that may request user input.

 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
 
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
 
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
