GJC compatibility campaign: Rust fork-in-spirit of gajae-code #3319

Objective

Make ultraworkers/claw-code a Rust fork-in-spirit of gajae-code (GJC), achieving SDK compatibility and capability compatibility.

Reference Implementation

Read-only: /home/bellman/Workspace/gajae-code (gajae-code SDK, tools, skills, settings)

Phase Overview

Phase 1: Foundation (SDK Wire Protocol)

• WebSocket transport with frame correlation
• Operation registry and error handling
• Session routing and reconciliation

Phase 2: Core Capabilities

• Complete 55-tool catalog (35/55 done, 20 gaps)
• Skill discovery enhancement (bundled registry, chaining)
• Task execution integration

Phase 3: Polish

• Session-level settings override
• 120+ slash commands (40/120+ done, 80 gaps)
• Integration and optimization

Deliverables

• Gap matrix analysis (docs/gjc-compat/gap-matrix.md)
• SDK wire protocol implementation (new sdk crate, 4.5K LOC)
• Session lifecycle SDK integration (2.5K LOC)
• Tool catalog completion (3.5K LOC)
• Skill system enhancement (1.4K LOC)
• Slash command expansion (3.2K LOC)
• Settings & configuration (0.5K LOC)
• Integration tests and verification

Sub-Issues

See linked issues below for per-slice work.

Acceptance Criteria

• All sub-issues closed with acceptance criteria met
• SDK transport test passes with mock server
• Session lifecycle operations work end-to-end
• Tool execution matches GJC behavior
• Skill discovery finds all scopes (bundled, project, user)
• All AGENTS.md tests pass
• Public docs contain no internal paths, hosts, or private infra
