Critical: Fix agentic-jujutsu compilation errors and WASM build

Critical Issues: agentic-jujutsu Package

Overview

The agentic-jujutsu package requires critical fixes to become functional. Current status: 59 compilation errors blocking all functionality.

Priority 0: WASM Build Failure

Issue: errno crate incompatibility with wasm32-unknown-unknown target
Impact: Complete WASM build failure
Estimated Time: 2-4 hours

Fix Required:

[target.'cfg(not(target_arch = "wasm32"))'.dependencies]
errno = "0.3"

Priority 1: 59 Compilation Errors

Category Breakdown:

• Field type mismatches: 15 errors (src/hooks.rs, src/agentdb_sync.rs)
• WASM binding violations: 24 errors (String fields need #[skip])
• Type mismatches: 12 errors (DateTime vs i64)
• Duplicate functions: 1 error (wrapper.rs:261)
• Trait bound violations: 10 errors (OperationType enum)

Top 3 Critical Errors:

1. Field Mismatches in hooks.rs (Lines 163-166)

Current (broken):

let operation = JJOperation {
    description: description.clone(),  // ❌ Field doesn't exist
    timestamp: ctx.timestamp,          // ❌ Type mismatch
    args: vec![],                      // ❌ Field doesn't exist
};

Fixed:

let operation = JJOperation::builder()
    .operation_id(uuid::Uuid::new_v4().to_string())
    .command(description.clone())
    .user(ctx.agent_id.clone())
    .hostname("hook-agent".to_string())
    .build();

2. Duplicate Function in wrapper.rs:261

Rename commit creation method:

pub async fn new_commit(&self, message: Option<&str>) -> Result<JJResult>

3. WASM String Fields

Make String fields private with getters:

#[wasm_bindgen]
pub struct JJConfig {
    #[wasm_bindgen(skip)]
    jj_path: String,
    
    #[wasm_bindgen(getter)]
    pub fn jj_path(&self) -> String { self.jj_path.clone() }
}

Priority 2: Security Hardening

Estimated Time: 2-3 hours

Required Validations:

1. Command injection prevention in wrapper.rs
2. Path traversal protection in config.rs
3. Input sanitization for all user inputs

Implementation Strategy

Based on gist analysis (https://gist.github.com/ruvnet/29d28cf48c2be8e75704b7474c6a78ba), implement:

Multi-Agent Architecture

• JJ workspace isolation (N workspaces per agent)
• Anonymous branch workflow
• Automatic 3-way conflict merging
• 60-80% auto-resolution of conflicts

Performance Optimization

• 352x faster code transformations (Agent Booster)
• Sub-millisecond reasoning retrieval (AgentDB)
• Three-layer caching hierarchy (85-92% hit rates)
• Batch commits: 5-20 commits (5.6x speedup)

Integration Requirements

• QUIC protocol integration (50-70% latency reduction)
• AgentDB vector search (<1ms query latency)
• Agentic-Flow orchestration (213 MCP tools)
• Cost optimization (Tier 2: $0.14-0.28 per million tokens)

Deliverables

• Fix all 59 compilation errors
• Fix WASM build configuration
• Implement security hardening
• Run full test suite (150+ tests)
• Execute benchmarks
• Validate 80%+ test coverage
• Performance validation against baselines

Timeline

• Week 1-2: Fix compilation errors, WASM build, security
• Week 3-4: Test suite validation, benchmarking
• Week 5-6: Multi-agent workspace implementation
• Week 7-8: Performance optimization, monitoring

Expected Outcomes

• 100% compilation success
• 80%+ test coverage
• 352x code transformation performance
• <1ms AgentDB query latency
• 60-80% auto-conflict resolution
• $410K-$1.09M annual savings (10-agent teams)

• Commit: 5fee11c (deep review and optimization framework)

Start with packages/agentic-jujutsu/docs/REVIEW_REPORT.md and VALIDATION_REPORT.md, then inspect src/hooks.rs, src/agentdb_sync.rs, wrapper.rs, and config.rs. Run the WASM build and full test suite to reproduce the reported compilation and security issues. Done requires resolving the 59 errors, passing the WASM build and 150+ tests, and completing the listed security, benchmark, and coverage validation.
