 - Claude Code source code is at /Users/imbenji/StudioProjects/clawd_code/old_repo
 - "Claude Code" refers to the original TypeScript source in /old_repo
 - "the Agency" refers to the Dart/Flutter project (lib/, pubspec.yaml, etc.)
+- `lib/src/` → Core logic that must have parity with Claude Code
+- `lib/ui/` → Flutter UI layer with creative freedom
 
 ## Parity rule
 
-The Agency must always have parity with Claude Code. Before implementing any feature or behaviour in the Agency, check how Claude Code does it in /old_repo first. If something in the Agency diverges from how Claude Code works, treat that as a bug and fix it to match.
+`lib/src/` must always have parity with Claude Code. Before implementing any feature or behaviour in `lib/src/`, check how Claude Code does it in `/old_repo` first. If something in `lib/src/` diverges from how Claude Code works, treat that as a bug and fix it to match.
 
 Always assume any implementation should achieve **full parity** with Claude Code — never a simplified version. If the Claude Code implementation is complex, implement it with the same complexity. Do not simplify unless the user explicitly says to.
+
+`lib/ui/` should have some parity with the Claude Code UI (ink components), but not full 1:1 parity — creative freedom is allowed for the Flutter implementation.
+
+- After writing Flutter code, always run `flutter analyze 2>&1 | grep -E "^\s*(error)" ` before wrapping up.
+
+## Known parity gaps in `lib/src/`
+
+When a file in `lib/src/` strays from Claude Code behaviour, mark it with a `// PARITY GAP:` comment at the diverging code. Also list it here:
+
+- **`lib/src/chat/tool_loop_service.dart`** — Skips image resize/downsample (`maybeResizeAndDownsampleImageBlock`) and does not store pasted images to disk (`storeImages`). Claude Code does both in `processUserInput.ts`.
+- **`lib/ui/providers/chat_provider.dart`** (UI layer) — Images sent as OpenAI-format `image_url` data URLs (OpenRouter requirement) instead of Anthropic-format base64 blocks. Uses a flat attachment list instead of Claude Code's `PastedContent` ID-ref system. Non-image files embedded as plain text rather than document blocks. See `handlePromptSubmit.ts` + `processUserInput.ts`.

+# Agency vs Claude Code — Differences
+
+_Last updated: 2025-07-14_
+
+---
+
+## 1. API Backend — Fundamental Difference
+
+| | Claude Code | The Agency |
+|---|---|---|
+| API | **Anthropic SDK** directly (claude-opus-4 etc.) | **OpenRouter** (OpenAI-compatible chat completions) |
+| Auth | Anthropic API key / OAuth | OpenRouter API key |
+| Message format | Anthropic's native format (content blocks array) | OpenAI chat completions format (`role`/`content` strings, `tool_calls`) |
+| Streaming | SSE via Anthropic SDK | SSE via raw HTTP, `LineSplitter` |
+
+---
+
+## 2. UI — Completely Different Paradigm
+
+| | Claude Code | The Agency |
+|---|---|---|
+| Interface | **Terminal TUI** (Ink/React in the terminal) | **Flutter desktop app** (macOS GUI) |
+| Rendering | Custom terminal renderer, ANSI, Yoga layout | Flutter widgets, `shadcn_flutter` |
+| Input | Keyboard-driven, vim mode, raw stdin | Mouse + keyboard, text fields, buttons |
+
+---
+
+## 3. Bash Permission System — Major Gap
+
+This is the biggest functional divergence. Claude Code's `bashPermissions.ts` has ~2,600 lines of sophisticated security analysis:
+
+- **Tree-sitter AST parsing** — parses the actual bash AST to detect injections, `too-complex` structure, etc.
+- **20+ security validators** — backslash-escaped operators, brace expansion, unicode whitespace, mid-word `#`, quoted newlines, carriage return differentials, IFS injection, `zmodload`/zsh dangerous commands, ANSI-C quoting obfuscation, heredoc-in-substitution, process substitution, malformed tokens, etc.
+- **Classifier** — a Haiku-based ML classifier for allow/deny/ask rules described in natural language (e.g. "don't run anything that deletes files")
+- **Compound command splitting** — splits `cmd1 && cmd2` and checks each subcommand independently, with cd+git security checks
+- **Safe wrapper stripping** — `timeout`, `nohup`, `nice`, `stdbuf` stripped before rule matching
+- **Speculative classifier** — starts the AI classifier check in parallel while the permission dialog is shown
+
+The Agency's `PermissionManager` is a stub by comparison — a simple string-matching check against allow/deny rules.
+
+---
+
+## 4. Missing Tools
+
+Claude Code has many tools the Agency doesn't:
+
+| Tool | Claude Code | Agency |
+|---|---|---|
+| `LSPTool` | ✅ (go-to-def, hover, diagnostics) | ❌ |
+| `AskUserQuestionTool` | ✅ | ❌ |
+| `NotebookEditTool` | ✅ (Jupyter) | ❌ |
+| `PowerShellTool` | ✅ | ❌ |
+| `TodoWriteTool` | ✅ | ❌ |
+| `ConfigTool` | ✅ | ❌ |
+| `EnterPlanModeTool` / `ExitPlanModeTool` | ✅ | ❌ |
+| `EnterWorktreeTool` / `ExitWorktreeTool` | ✅ | ❌ |
+| `BriefTool` | ✅ | ❌ |
+| `ListMcpResourcesTool` / `ReadMcpResourceTool` | ✅ | ❌ |
+| `ScheduleCronTool` | ✅ | ❌ |
+| `TaskCreate/Get/List/Update/Stop/Output` | ✅ (separate tools) | Merged into `ExecuteTask` |
+| `REPLTool` | ✅ | ❌ |
+| `SendMessageTool` | ✅ | ❌ |
+| `SleepTool` | ✅ | ❌ |
+| `TeamCreateTool` / `TeamDeleteTool` | ✅ | ❌ |
+| `ToolSearchTool` | ✅ | ❌ |
+
+---
+
+## 5. Plan Mode / Worktree Mode
+
+Claude Code has distinct **plan mode** (read-only, no writes) and **worktree mode** (isolated git worktrees for parallel agents). The Agency has no equivalent.
+
+---
+
+## 6. Agent Architecture
+
+Claude Code has a full multi-agent swarm system:
+- Built-in agents: `exploreAgent`, `planAgent`, `verificationAgent`, `generalPurposeAgent`, `claudeCodeGuideAgent`
+- `forkSubagent` — spawns sub-agents in parallel tmux panes or in-process
+- Permission forwarding between leader/worker agents
+- Agent memory snapshots
+
+The Agency has a simpler single-level advisor pattern (one extra model call for a second opinion).
+
+---
+
+## 7. Analytics / Statsig / Feature Gates
+
+Claude Code has Statsig feature gates, GrowthBook, analytics events (`logEvent`) throughout. The Agency has stub analytics.
+
+---
+
+## 8. Migrations, Slash Commands, Voice, Vim Mode
+
+All present in Claude Code (`/commit`, `/review`, `/advisor`, `/brief`, vim insert/normal/visual modes, voice input) — none in the Agency.
+
+---
+
+## 9. Bridge / Remote Control
+
+Claude Code has a full REPL bridge for remote control (VS Code extension, web UI, etc.) with JWT auth, polling, session runners, and flush gates. The Agency has a bridge stub but it's not the same system.
+
+---
+
+## Summary
+
+The Agency has the **skeleton** of Claude Code (tool loop, session history, CLAUDE.md system prompt injection, hooks, MCP types), but is missing the **security depth**, **tool breadth**, **agentic infrastructure**, and **AI-native UI conventions** of the original.

+
+Carefully consider the reversibility and blast radius of actions. Generally you can freely take local, reversible actions like editing files or running tests. But for actions that are hard to reverse, affect shared systems beyond your local environment, or could otherwise be risky or destructive, check with the user before proceeding. The cost of pausing to confirm is low, while the cost of an unwanted action (lost work, unintended messages sent, deleted branches) can be very high. For actions like these, consider the context, the action, and user instructions, and by default transparently communicate the action and ask for confirmation before proceeding. This default can be changed by user instructions - if explicitly asked to operate more autonomously, then you may proceed without confirmation, but still attend to the risks and consequences when taking actions. A user approving an action (like a git push) once does NOT mean that they approve it in all contexts, so unless actions are authorized in advance in durable instructions like CLAUDE.md files, always confirm first. Authorization stands for the scope specified, not beyond. Match the scope of your actions to what was actually requested.
+
+Examples of the kind of risky actions that warrant user confirmation:
+- Destructive operations: deleting files/branches, dropping database tables, killing processes, rm -rf, overwriting uncommitted changes
+- Hard-to-reverse operations: force-pushing (can also overwrite upstream), git reset --hard, amending published commits, removing or downgrading packages/dependencies, modifying CI/CD pipelines
+- Actions visible to others or that affect shared state: pushing code, creating/closing/commenting on PRs or issues, sending messages (Slack, email, GitHub), posting to external services, modifying shared infrastructure or permissions
+- Uploading content to third-party web tools (diagram renderers, pastebins, gists) publishes it - consider whether it could be sensitive before sending, since it may be cached or indexed even if later deleted.
+
+When you encounter an obstacle, do not use destructive actions as a shortcut to simply make it go away. For instance, try to identify root causes and fix underlying issues rather than bypassing safety checks (e.g. --no-verify). If you discover unexpected state like unfamiliar files, branches, or configuration, investigate before deleting or overwriting, as it may represent the user's in-progress work. For example, typically resolve merge conflicts rather than discarding changes; similarly, if a lock file exists, investigate what process holds it rather than deleting it. In short: only take risky actions carefully, and when in doubt, ask before acting. Follow both the spirit and letter of these instructions - measure twice, cut once.""";
