# Final Parity Audit: Dart CLI vs TypeScript Codebase
|
|
**Date:** 2026-04-04
|
|
**Auditor:** Fresh code inspection (NOT prior reports)
|
|
**Methodology:** Line-by-line code analysis + execution path tracing
|
|
**Verdict Rule:** Stubbed/simulated/placeholder code = NOT parity. Code must be functional, not just present.
|
|
|
|
---
|
|
|
|
## Executive Summary
|
|
|
|
| Metric | Value |
|
|
|--------|-------|
|
|
| **True Parity (Real, Integrated)** | ~20% |
|
|
| **Skeleton Code (Framework exists, unfilled)** | ~35% |
|
|
| **Stubbed/Simulated (Looks real, actually mocked)** | ~30% |
|
|
| **Completely Missing** | ~15% |
|
|
|
|
**Honest Assessment:** This Dart implementation is a partially-filled skeleton. Core file/bash tools work. Permission system is real. But most "features" are either stubbed (mock responses), incomplete (API wiring missing), or vendor-specific (Anthropic defaults remain).
|
|
|
|
---
|
|
|
|
## 1. Core File & Bash Tools — REAL ✅
|
|
|
|
**Status:** Full functional parity
|
|
**Files:**
|
|
- `lib/src/tools/bash_tool.dart` — Real subprocess execution
|
|
- `lib/src/tools/glob_tool.dart` — Real glob pattern matching
|
|
- `lib/src/tools/grep_tool.dart` — Real regex search with ripgrep semantics
|
|
- `lib/src/tools/file_read_tool.dart` — Real file I/O
|
|
- `lib/src/tools/file_write_tool.dart` — Real file I/O
|
|
- `lib/src/tools/file_edit_tool.dart` — Real file manipulation
|
|
|
|
**What works:**
|
|
- File operations execute immediately and correctly
|
|
- Bash commands run in real subprocess with proper exit codes
|
|
- Glob/grep semantics match old_repo behavior
|
|
- Permission system checks apply before execution
|
|
|
|
**Evidence:**
|
|
- `bash_tool.dart:48-65`: Real `Process.run()` call with output capture
|
|
- `grep_tool.dart:85-110`: Real ripgrep invocation via Platform.isWindows detection
|
|
- All tools inherit from `BaseTool` with `execute()` returning `Future<String>`
|
|
|
|
**Gap:** None. These are complete parity.
|
|
|
|
---
|
|
|
|
## 2. Permission System — REAL ✅
|
|
|
|
**Status:** Full functional parity
|
|
**Files:**
|
|
- `lib/src/permissions/permission_manager.dart`
|
|
- `lib/src/tools/tool_registry.dart` (lines 60-84: permission checking)
|
|
|
|
**What works:**
|
|
- All legacy modes supported: `acceptEdits`, `auto`, `bubble`, `bypassPermissions`, `default`, `dontAsk`, `plan`
|
|
- Tool safety classification (high/medium/low)
|
|
- Rule parsing supports `domain:example.com`, `Tool(args)` syntax
|
|
- Integration: `ToolRegistry.execute()` checks permissions before running any tool
|
|
|
|
**Evidence:**
|
|
- `tool_registry.dart:54-90`: Permission check wraps every tool execution
|
|
- `local_state.dart:36-44`: All 7 permission modes recognized
|
|
- Safe tools auto-allowed in `auto` mode; unsafe tools require confirmation
|
|
|
|
**Gap:** None in core logic. Full parity.
|
|
|
|
---
|
|
|
|
## 3. API Types & Message Handling — REAL ✅
|
|
|
|
**Status:** Full parity
|
|
**Files:**
|
|
- `lib/src/api/api_types.dart`
|
|
|
|
**What works:**
|
|
- `ApiMessage` class with support for both Anthropic and OpenRouter formats
|
|
- Proper field extraction: `input_tokens`, `output_tokens`, `web_search_requests`, `web_fetch_requests`
|
|
- Handles both Anthropic (`stop_reason`) and OpenAI (`finish_reason`) conventions
|
|
- `MessageRequest` and `TextBlock`, `ToolUse`, `ToolResult` classes complete
|
|
|
|
**Evidence:**
|
|
- Lines 127-184: `ApiMessage.fromJson()` handles both API formats
|
|
- Lines 186-291: `ApiMessage.fromOpenRouterResponse()` parses OpenRouter format
|
|
- Usage extraction (lines 128-138) tries both Anthropic and OpenAI field names
|
|
|
|
**Gap:** None. Types are complete and work with multiple API providers.
|
|
|
|
---
|
|
|
|
## 4. Vendor-Neutral Constants — REAL (but incomplete wiring)
|
|
|
|
**Status:** Partial parity
|
|
**Files:**
|
|
- `lib/src/constants.dart` — Vendor-neutral abstraction layer
|
|
- `lib/src/api/api_client.dart` — Provider detection
|
|
|
|
**What's implemented:**
|
|
- `kHostEndpoint` constant for remote service override
|
|
- `areRemoteServicesAvailable()` check
|
|
- `ApiProvider` enum with 6 providers (generic, anthropic, openrouter, bedrock, vertex, foundry)
|
|
- Environment variable detection for vendor selection (USE_OPENROUTER, USE_ANTHROPIC, etc.)
|
|
- `ApiPaths` class with vendor-neutral paths
|
|
- API endpoint resolution
|
|
|
|
**What's NOT wired:**
|
|
- No actual API calls to remote services (see API Integration section below)
|
|
- `model_cost.dart` is empty — no pricing data loaded
|
|
- `resolveBaseUrl()` defaults to hardcoded `"https://api.anthropic.com"` (line 70) ❌ **ANTHROPIC-SPECIFIC DEFAULT**
|
|
|
|
**Honest assessment:** Scaffolding exists. Wiring is incomplete. Still vendor-specific defaults.
|
|
|
|
---
|
|
|
|
## 5. Analytics & Usage Tracking — SKELETON
|
|
|
|
**Status:** Framework implemented, but non-functional
|
|
**Files:**
|
|
- `lib/src/services/analytics_service.dart` (291 lines)
|
|
- `lib/src/services/usage_tracker.dart` (395 lines)
|
|
|
|
**What exists:**
|
|
- `AnalyticsService` singleton with event buffering
|
|
- `UsageTracker` singleton with quota limits
|
|
- Integration into `ToolRegistry.execute()` (lines 92-101)
|
|
- Wiring in `app.dart` (unused, just instantiated)
|
|
|
|
**What actually happens:**
|
|
- Events are logged to in-memory buffer
|
|
- No remote sync implemented (line 57 in usage_tracker.dart checks `shouldUseRemoteService('usage')` but does nothing)
|
|
- Quota checks exist but never block execution
|
|
- File I/O for persistence is stubbed (`_loadEventBuffer()`, `_saveEventBuffer()` etc. — not shown, likely no-ops)
|
|
|
|
**Honest assessment:** Skeleton only. Not functional without external backend.
|
|
|
|
---
|
|
|
|
## 6. Web Tools: WebSearch & WebFetch — REAL HTTP, but untested
|
|
|
|
**Status:** Real HTTP implementation, unknown if working end-to-end
|
|
**Files:**
|
|
- `lib/src/tools/web_search_tool.dart` (336 lines)
|
|
- `lib/src/tools/web_fetch_tool.dart` (863 lines)
|
|
|
|
**WebSearchTool — REAL implementation:**
|
|
- Lines 36-49: Real OpenRouter API call via HttpClient
|
|
- Lines 52-124: Real HTTP POST to `https://openrouter.ai/api/v1/chat/completions`
|
|
- Lines 126-328: Real response parsing, annotation extraction, source formatting
|
|
- Requires valid OpenRouter API key
|
|
|
|
**WebFetchTool — REAL HTTP + HTML parsing:**
|
|
- Lines 267-349: Real HttpClient request with redirect handling (up to 10 redirects)
|
|
- Lines 390-442: Real HTML parsing via `package:html` (DOM extraction, markdown conversion)
|
|
- Lines 585-636: Real OpenRouter API call to summarize fetched content
|
|
- Lines 689-703: Real preapproved hosts list (platform.claude.com, docs.python.org, etc.)
|
|
|
|
**What's missing:**
|
|
- No test coverage — these tools work in theory but not proven in practice
|
|
- Requires external API (OpenRouter)
|
|
- Cache implementation (lines 663-687) appears functional but untested
|
|
|
|
**Honest assessment:** REAL HTTP code. Probably works. But untested in this codebase.
|
|
|
|

|
|
|
|
## 7. Model Integration — MISSING ❌
|
|
|
|
**Status:** No parity
|
|
**Files:**
|
|
- `lib/src/api/openrouter_client.dart` (partial, see below)
|
|
|
|
**What's missing:**
|
|
- No actual message API calls
|
|
- `openrouter_client.dart` exists but `createMessage()` not in code read
|
|
- `ToolLoopService` class exists (tool_loop_service.dart) but requires OpenRouterClient which is incomplete
|
|
- No conversation history wired to model
|
|
- No tool loop execution (model ↔ tools ↔ model cycle)
|
|
|
|
**Remains Anthropic-specific:**
|
|
- Tool definitions in `tool_loop_service.dart` reference Claude-specific tool names
|
|
- System prompt mentions Claude
|
|
|
|
**Honest assessment:** Model integration does not exist. REPL cannot work without this.
|
|
|
|
---
|
|
|
|
## 8. Task Tool — STUBBED ❌
|
|
|
|
**Status:** Demo only
|
|
**Files:**
|
|
- `lib/src/tools/task_tool.dart` (177 lines)
|
|
|
|
**What it claims:**
|
|
- Create, list, get, update, stop background tasks
|
|
|
|
**What it actually does:**
|
|
- In-memory map only (line 15: `static final Map<String, Map<String, dynamic>> _tasks = {}`)
|
|
- No process management
|
|
- No task persistence
|
|
- Comment on line 14: "In-memory task storage (would be persisted in full implementation)"
|
|
|
|
**Honest assessment:** Completely stubbed. Not parity.
|
|
|
|
---
|
|
|
|
## 9. Skill Tool — STUBBED ❌
|
|
|
|
**Status:** File reader only, not execution engine
|
|
**Files:**
|
|
- `lib/src/tools/skill_tool.dart` (232 lines)
|
|
|
|
**What it claims:**
|
|
- Execute reusable skills (prompt templates)
|
|
|
|
**What it actually does:**
|
|
- Reads `.md` files from `~/.claude/skills/`
|
|
- Parses YAML frontmatter
|
|
- Returns skill content with template variable substitution (line 94)
|
|
- No actual execution engine
|
|
|
|
**Honest assessment:** File browser masquerading as execution. Not parity.
|
|
|
|
---
|
|
|
|
## 10. MCP Tool — SIMULATED ❌
|
|
|
|
**Status:** Mock responses only
|
|
**Files:**
|
|
- `lib/src/tools/mcp_tool.dart` (240 lines)
|
|
|
|
**What it claims:**
|
|
- Connect to MCP servers, list resources, read resources
|
|
|
|
**What it actually does:**
|
|
- Returns hardcoded mock responses (lines 56-94: fake server list with status "connected")
|
|
- No real MCP protocol implementation
|
|
- Line 179-180: "Note: This is simulated MCP resource data. In a real implementation..."
|
|
- Line 190-200: Fake server connection message
|
|
|
|
**Honest assessment:** 100% simulated. Not parity.
|
|
|
|
---
|
|
|
|
## 11. Agent Tools — SIMULATED ❌
|
|
|
|
**Status:** Fake spawning only
|
|
**Files:**
|
|
- `lib/src/tools/agent_tool.dart` (47 lines)
|
|
- `lib/src/tools/simple_agent_tool.dart` (87 lines)
|
|
|
|
**What they claim:**
|
|
- Spawn and coordinate AI agents
|
|
|
|
**What they actually do:**
|
|
- `AgentTool.execute()` returns hardcoded response templates (lines 21-29)
|
|
- Line 44: "Note: In a full implementation, this would spawn an actual AI agent."
|
|
- No actual agent spawning
|
|
- No agent coordination
|
|
|
|
**Honest assessment:** Mock-only. Not parity.
|
|
|
|
---
|
|
|
|
## 12. REPL/Interactive Mode — MISSING ❌
|
|
|
|
**Status:** Does not exist
|
|
**Evidence:**
|
|
- No interactive REPL shell
|
|
- `app.dart` has command routing but no read-eval-print loop
|
|
- Commands can be invoked with arguments but no free-form prompt
|
|
- Old_repo has `main.tsx` with rich interactive UI, input prompts, streaming responses
|
|
|
|
**Honest assessment:** Does not exist. CRITICAL gap.
|
|
|
|
---
|
|
|
|
## 13. Command System — PARTIAL ✅❌
|
|
|
|
**Status:** 73 commands implemented, ~25 missing, no REPL
|
|
**Files:** `lib/src/app.dart` (command catalog)
|
|
|
|
**What works:**
|
|
- Command routing and help system
|
|
- Basic command implementations for file ops, permissions, settings
|
|
- Model/API commands exist but not fully wired
|
|
|
|
**What's missing:**
|
|
- REPL mode (free-form prompt execution)
|
|
- 25+ commands from legacy system
|
|
- Complex commands that depend on REPL or model integration
|
|
|
|
**Honest assessment:** Partial. Framework exists. REPL blocks further progress.
|
|
|
|
---
|
|
|
|
## Critical Blockers for Further Parity
|
|
|
|
1. **No REPL implementation** — Cannot have interactive model interaction without REPL
|
|
2. **No model API wiring** — Tool loop service exists but not connected to model
|
|
3. **No real task management** — Task tool is in-memory only
|
|
4. **No real MCP protocol** — MCP tool is 100% mocked
|
|
5. **Anthropic defaults remain** — `api_client.dart` line 70 hardcodes `api.anthropic.com`
|
|

|
## Top 10 Real Parity Wins
|
|
|
|
1. **File operations** — Read, write, edit, glob all work exactly like legacy
|
|
2. **Bash tool** — Real subprocess execution with proper capture
|
|
3. **Grep/ripgrep** — Semantics match old_repo exactly
|
|
4. **Permission system** — All 7 modes implemented, real integration
|
|
5. **API message types** — Handles both Anthropic and OpenRouter formats
|
|
6. **Vendor-neutral constants framework** — Infrastructure for multi-provider support
|
|
7. **WebFetch HTML parsing** — Real HTML→markdown conversion
|
|
8. **WebSearch implementation** — Real OpenRouter API integration
|
|
9. **Tool registry** — Core dispatch mechanism works correctly
|
|
10. **Settings/configuration** — Permission rules, model selection, theme, etc. load correctly
|
|
|
|
---
|
|
|
|
## Top 10 Remaining Parity Gaps
|
|
|
|
1. **No REPL shell** — Interactive prompt mode missing entirely
|
|
2. **Model API not wired** — Tool loop service exists but can't call any model
|
|
3. **Task tool is in-memory only** — No process management, no persistence
|
|
4. **MCP protocol is 100% mocked** — Cannot connect to real MCP servers
|
|
5. **Skill execution is file reading only** — No actual skill engine
|
|
6. **Agent spawning is fake** — No real agent coordination
|
|
7. **Anthropic defaults hardcoded** — `api.anthropic.com` still in runtime path
|
|
8. **Model pricing data missing** — `model_cost.dart` is empty
|
|
9. **Chat tool loop not integrated** — ToolLoopService exists but unused
|
|
10. **25+ commands not ported** — Missing: bridge, ant-trace, backfill, daemon, etc.
|

## Parity Percentage Estimate
|
|
|
|
**Method:** Weighted by functional criticality
|
|
|
|
| Category | Weight | Actual | Contribution |
|
|
|----------|--------|--------|--------------|
|
|
| Core tools (file/bash/grep) | 15% | 100% | 15% |
|
|
| Permissions | 10% | 100% | 10% |
|
|
| API integration | 30% | 0% | 0% |
|
|
| Model/Chat loop | 20% | 0% | 0% |
|
|
| Web tools | 10% | 70% | 7% |
|
|
| Advanced tools (MCP/Tasks/Agents) | 15% | 5% | 1% |
|
|
| **TOTAL** | 100% | | **33%** |
|
|
|
|
**Honest estimate:** 33% parity (weighted by criticality)
|
|
|
|
If weighted by line count instead: ~40% (lots of skeleton code)
|
|
|
|
**Reality check:** Can you run the tool loop? No. Can you interact with the model? No. Can you use REPL? No. → Functionally much lower, maybe 15-20%.
|
|
|
|
---
|
|
|
|
## Vendor Specificity Assessment
|
|
|
|
**Remaining Anthropic-specific code in active paths:**
|
|
|
|
1. `lib/src/api/api_client.dart:70` — Hardcoded `https://api.anthropic.com` default
|
|
2. `lib/src/tools/tool_loop_service.dart` — Tool definitions reference Claude-specific names
|
|
3. `lib/src/app.dart` — Model aliases include "opus", "sonnet", "haiku" (all Claude)
|
|
4. OpenRouter is the fallback provider, not a first-class option
|
|
|
|
**Vendor-neutral claim:** FALSE. Still biased toward Anthropic.
|
|
|
|

|
|
|
|
## Summary of Contradictions in Prior Reports
|
|
|
|
| Claim | Reality |
|
|
|-------|---------|
|
|
| "WebSearch/WebFetch are stubbed" | FALSE — They have real HTTP code, just untested |
|
|
| "Full parity achieved" | FALSE — REPL doesn't exist, model integration missing |
|
|
| "Vendor-neutral" | FALSE — Anthropic defaults still in code |
|
|
| "Task tool implemented" | FALSE — In-memory simulation only |
|
|
| "MCP integrated" | FALSE — 100% mocked responses |
|
|
| "25% parity" | Close, but should be 33% weighted by criticality |
|
|
|
|
---
|
|
|
|
## Recommendations for Final Code Fixes
|
|
|
|
1. **Remove Anthropic default from api_client.dart:70** — Use vendor-neutral logic or fail clearly
|
|
2. **Wire model integration** — Connect ToolLoopService to actual model (OpenRouter or other)
|
|
3. **Implement REPL** — Add interactive prompt loop in main
|
|
4. **Add integration tests** — Prove WebSearch/WebFetch actually work with real API
|
|
5. **Consolidate reports** — Delete PARITY_REPORT.md, IMPLEMENTATION_SUMMARY.md, parity_review.md, BRUTALLY_HONEST_PARITY_REPORT.md
