# GJC Compatibility Gap Matrix
**Document Status**: Phase 1 Analysis (2026-10-13)
**Scope**: SDK wire protocol, session lifecycle, tools, skills, settings, hooks, commands, and AGENTS.md rules
**Target**: Rust fork-in-spirit of gajae-code (GJC) SDK-compatible and capability-compatible
---
## 1. EXECUTIVE SUMMARY

---
## 2. SDK WIRE PROTOCOL
### GJC Behavior (gajae-code Reference)
**Source**: `packages/coding-agent/src/sdk/client/client.ts`, `sdk/host/session-runtime.ts`
GJC uses a **WebSocket-based JSON-RPC-like protocol** with:
- **Transport**: WebSocket over TCP
- **Frame Format**: JSON object with typed fields
- **Correlation**: Request/response matched by `frame.id` (UUID)
- **Operations**: 65+ operation types (Q1-Q32, C01-C06, reverse ops)
- **Error Handling**: Typed `SdkErrorCode` with `uncertain_after_send` recovery
- **Reconnect**: Exponential backoff with deadline management
- **Request Timeout**: 10s default (`DEFAULT_SDK_REQUEST_TIMEOUT_MS`), per-request override
- **Handshake**: `client.hello` with capabilities advertised; `server.hello` response
**Operations** (sample):
- **Control**: `turn.create`, `turn.prompt`, `turn.steer`, `turn.abort_and_prompt`
- **Queries**: `turn.list`, `turn.get_one`, `turn.message_list`, `skill.source`, `artifact.content`
- **Reverse**: `ask.answer`, `tool.dispatch`, `tool.fetch_capability`
**Event Schema**:
```json
{
"id": "uuid-string",
"operation": "turn.create",
"input": { ... },
"connectionId": "optional",
"settings": { ... }
}
```
### claw-code Status
**Current**: Missing entirely. claw-code has no SDK wire protocol or external session API.
**Files**: None
**Lines**: 0
**Reality**:
- claw-code operates as a local CLI only (stdin/stdout/stderr).
- Sessions are file-based (`.claw/sessions/`).
- No remote access or external SDK clients.
- No WebSocket transport.
- No frame correlation or reconnect logic.
### Gap Assessment
| Component | GJC | claw-code | Gap | Complexity |
|-----------|-----|-----------|-----|------------|
| WebSocket Transport | 1500 LOC | — | 100% | High |
| Frame Correlation | 800 LOC | — | 100% | Medium |
| Operation Registry | 400 LOC | 0 | 100% | Medium |
| Error Handling & Recovery | 600 LOC | — | 100% | High |
| Handshake & Negotiation | 200 LOC | — | 100% | Low |
| **Total** | **3,500 LOC** | **0** | **3,500 LOC** | — |
### Proposed Implementation
**Owner Crate**: `sdk` (new)
**Module Structure**:
```
rust/crates/sdk/
├── Cargo.toml
└── src/
├── lib.rs (exports + top-level API)
├── client/
│ ├── mod.rs (SdkClient, WebSocket transport)
│ ├── correlation.rs (frame ID tracking, reconnect)
│ └── errors.rs (SdkErrorCode, recovery)
├── protocol/
│ ├── mod.rs (Operation registry)
│ ├── operations.rs (operation definitions)
│ └── schema.rs (JSON schemas, frame validation)
├── session/
│ ├── mod.rs (session lifecycle over SDK)
│ ├── router.rs (session routing, durable state)
│ └── reconciliation.rs (uncertain outcome recovery)
└── tests/
├── mod.rs
└── fixtures/ (mock server scenarios)
```
**Size Estimate**: 4,500 LOC (Rust + test fixtures)
**Dependencies**:
- `tokio` (async I/O, WebSocket)
- `tungstenite` (WebSocket protocol)
- `serde_json` (frame serialization)
- `uuid` (correlation IDs)
- `runtime` crate (session persistence bridge)
---
## 3. SESSION LIFECYCLE
### GJC Behavior (gajae-code Reference)
**Source**: `packages/coding-agent/src/sdk/host/session-runtime.ts`, `sdk/client/`, `sdk/lifecycle/`
GJC sessions have **three entry points**:
1. **Native SDK** (via WebSocket): typed `SdkClient` with `session.create`, `session.prompt`, etc.
2. **Browser ACP** (via iframe): same protocol, browser sandbox isolate
3. **CLI Daemon** (stdio): JSON-RPC over stdio for local CLI access
**Session Operations**:
- **create**: `turn.create(model, input)` → returns `sessionId`, persistent state written to broker DB
- **prompt**: `turn.prompt(request, tools, settings)` → streams events: `agent_begin`, `tool_use`, `tool_result`, `agent_end`
- **steer**: `turn.steer(overrides)` → mid-flight direction change (model, settings, system prompt)
- **abort**: `turn.abort_and_prompt()` → terminal failure + new prompt in one operation
- **list**: `turn.list(filters)` → paginated session history
- **get_one**: `turn.get_one(sessionId, turnId)` → single turn with full details
**State Persistence**:
- Invocation record (prompt request, outcome, correlation)
- Message buffer (system, assistant, tool results, agent events)
- Reconciliation store (uncertain → durable mapping)
- Terminal scope (last session per correlation key)
**Lifecycle Events**:
1. `turn_accepted` (immediate, transient)
2. `agent_begin` (before first model call)
3. `tool_use` + `tool_result` (interleaved)
4. `agent_end` (final model output)
5. `turn_ended` (durable, terminal outcome recorded)
### claw-code Status
**Current**: Partial. Local session lifecycle exists but no SDK transport or remote access.
**Files**:
- `rust/crates/runtime/src/session.rs` (1,961 LOC)
- `rust/crates/runtime/src/conversation.rs` (1,878 LOC)
- `rust/crates/runtime/src/session_control.rs` (file ops, migration)
- `rust/crates/runtime/src/lib.rs` (re-exports `Session`, `SessionStore`, `ConversationRuntime`)
**Lines**: ~3,900 LOC (session + conversation)
**Reality**:
- `Session` struct holds in-memory state (messages, usage, context).
- `SessionStore` reads/writes `.claw/sessions/{id}/` directory.
- `ConversationRuntime` drives the local agent loop (sync).
- No WebSocket or remote access.
- No invocation reconciliation or uncertain outcome recovery.
- No terminal scope tracking (per-session-per-correlation).
### Gap Assessment
| Component | GJC | claw-code | Gap | Complexity |
|-----------|-----|-----------|-----|------------|
| Remote Session Router | 2,500 LOC | — | 100% | High |
| Invocation Reconciliation | 1,200 LOC | — | 100% | High |
| Terminal Scope Tracking | 600 LOC | — | 100% | Medium |
| Async Event Streaming | 800 LOC | Partial | 60% | Medium |
| Uncertain Outcome Recovery | 1,000 LOC | — | 100% | High |
| **Total** | **6,100 LOC** | **3,900** | **2,200 LOC** | — |
### Proposed Implementation
**Owner Crate**: `sdk` (new, or extend `runtime`)
**Module Structure** (add to `sdk/session/`):
```
sdk/session/
├── router.rs (session routing, durable lookup)
├── reconciliation.rs (uncertain → terminal recovery)
├── terminal_scope.rs (per-correlation state retention)
└── events.rs (event publishing, reconciliation)
```
**Integration Points**:
- Bridge `runtime::Session` into `sdk::Session` wrapper
- Add `runtime::SessionStore` extensions for reconciliation data
- Extend `ConversationRuntime` with event emission
**Size Estimate**: 2,500 LOC (Rust, new + modifications)
---
## 4. TOOL CATALOG (55 Tools)
### GJC Behavior (gajae-code Reference)
**Source**: `packages/coding-agent/src/tools/` (55 tool files + shared harness)
GJC implements **55 distinct tools** across multiple domains:
- **File I/O**: `read`, `write`, `edit`, `search`, `find`
- **Shell**: `bash`, `sleep`
- **Task Delegation**: `task` (subagent spawning)
- **Workflow**: `skill`, `skill_discovery`, `goal`, `ask`
- **Search**: `search_tool_bm25` (semantic search discovery)
- **Image**: `image_gen` (DALL-E), `image_tag_scan`
- **Integration**: `web_fetch`, `web_search`, `custom_tool_fetch`
- **Developer**: `notebook_edit`, `command_repl`, `shell_repl`, `powershell`
- **Config**: `config_read`, `config_write` (settings, modes)
- **Structured**: `model_registry`, `cost_calculator`, `settings_apply`
- **Workflow Gates**: `workflow_gate_answer`, `workflow_plan_approve`
- **Move**: `move_cwd`, `move_session`
**Tool Execution Model**:
1. Input deserialized from JSON schema
2. Permission check (read-only vs. destructive)
3. Tool invocation with typed inputs
4. Structured output or error
5. Result published to agent loop
**Permission Gating**: Every tool has a `required_permission` (read-only, approve, unsafe).
### claw-code Status
**Current**: Partial. 35 tools implemented, 20 missing or incomplete.
**Files**: `rust/crates/tools/src/lib.rs` (10,892 LOC, single file with all 55 spec + implementations)
**Implemented Tools** (~35):
- `read`, `write`, `edit`, `search`, `find`

| **Total** | **11,500 LOC** | **8,000** | **3,500 LOC** | — |
### Proposed Implementation
**Owner Crate**: `tools` (expand existing)
**New Modules**:
```
rust/crates/tools/src/
├── tools/
│ ├── image_gen.rs (DALL-E integration)
│ ├── ask_interactive.rs (blocking user prompts)

## 5. SKILL DISCOVERY & INVOCATION
### GJC Behavior (gajae-code Reference)
**Source**: `packages/coding-agent/src/tools/skill-discovery.ts`, `packages/coding-agent/src/tools/skill.ts`, `packages/coding-agent/src/sdk-skills/`
GJC supports **dynamic skill loading** with:
- **Discovery**: `skill_discovery` tool scans `.gjc/skills/`, project `.gjc/skills/`, bundled skills
- **Frontmatter Parsing**: YAML headers in `SKILL.md` define metadata (name, description, use conditions)
- **Invocation**: `skill` tool loads and executes a named skill (skill name + args)
- **Skill Execution**: Skill = subprocess call to `gjc /skill:<name>` with args
- **Bundled Skills**: `autoresearch`, `deep-interview`, `ralplan`, `ultragoal`
- **Project Skills**: Discoverable from `.gjc/skills/*/SKILL.md`
- **User Skills**: Discoverable from `~/.gjc/skills/*/SKILL.md`
**Skill Metadata**:
```yaml
# /skill:my-skill
# description: What this skill does
# scope: project | user | bundled
# requires: List of capabilities
```
**Skill Discovery Result**:
```json
{
"name": "skill-name",
"description": "...",
"path": "...",
"bundled": true | false,
"scope": "project" | "user" | "bundled"
}
```
### claw-code Status
**Current**: Basic. Skill discovery exists but limited to filesystem scanning.
**Files**:
- `rust/crates/tools/src/lib.rs` (skill_discovery + skill dispatch, ~200 LOC)
- `rust/crates/runtime/src/prompt.rs` (skill loading in prompts, ~100 LOC)
**Implementation**:
- Scans `.claw/skills/` directory for `SKILL.md` files
- Parses frontmatter (basic YAML)
- Returns discovery results as JSON
- `skill` tool invokes skill as subprocess
**Missing**:
- Bundled skill registry (autoresearch, deep-interview, ralplan, ultragoal)
- Project + user skill discovery hierarchy
- Frontmatter validation and standardization
- Skill chaining (`skill()` tool to invoke another skill from within a skill)
- Skill state persistence (workflow handoff)
### Gap Assessment
| Component | GJC | claw-code | Gap | Complexity |
|-----------|-----|-----------|-----|------------|
| Bundled Skill Registry | 200 LOC | — | 100% | Low |
| Frontmatter Parser | 150 LOC | 100 LOC | 30% | Low |
| Project + User Discovery | 300 LOC | Basic | 70% | Low |
| Skill Chaining | 250 LOC | — | 100% | Medium |
| Workflow State Handoff | 400 LOC | — | 100% | Medium |
| Skill Execution Harness | 200 LOC | Partial | 40% | Low |
| **Total** | **1,500 LOC** | **100** | **1,400 LOC** | — |
### Proposed Implementation
**Owner Crate**: `tools` (expand existing) or `skills` (new, lightweight)
**Module Structure**:
```
rust/crates/tools/src/
├── skill_discovery.rs (enhanced parsing, project/user/bundled hierarchy)
├── skill_execution.rs (subprocess dispatch, state handoff)
├── bundled_skills.rs (registry of autoresearch, deep-interview, ralplan, ultragoal)
└── skill_state.rs (workflow handoff serialization)
```
**Size Estimate**: 1,400 LOC (Rust)
**Integration**:
- Extend `skill_discovery` tool to search three scopes (bundled, project, user)
- Add `skill` tool support for chaining (returning another skill invocation)
- Store workflow state in durable files for handoff
---
## 6. SETTINGS & CONFIGURATION
### GJC Behavior (gajae-code Reference)
**Source**: `packages/coding-agent/src/config.ts`, `packages/coding-agent/src/sdk/host/session-runtime.ts`
GJC supports **settings override** at multiple levels:
1. **Global Settings**: `~/.gjc/config.json` (user defaults)
2. **Session Settings**: per-session override via `turn.create` or `turn.prompt` input
3. **Runtime Override**: `settings` field in SDK request frames
4. **Setting Categories**:
- **Model**: `modelName`, `modelTemperature`, `modelMaxTokens`
- **Behavior**: `allowance`, `permissions.*`, `features.*`
- **UX**: `theme`, `shell`, `notification*`
- **Advanced**: `memory.context`, `memory.compression`, `cost.*`
**Config Schema**: Typed with JSON schema validation per setting
**Permission Modes**:
- `read_only` (no execution)
- `approve` (interactive approval)
- `unsafe` (no gates)
### claw-code Status
**Current**: Partial. Config exists but no session-level override or setting propagation.
**Files**:
- `rust/crates/runtime/src/config.rs` (3,894 LOC, largest file in runtime)
- `rust/crates/runtime/src/config_validate.rs` (validation helpers)
**Implementation**:
- Reads `.claw/config.json` at startup
- Stores global settings (model, permissions, plugins, features)
- No session-level override
- No setting propagation through tool execution
- No typed setting validation against schema
**Missing**:
- Per-session setting override (session-specific model, permissions)
- Setting propagation to all tool invocations
- Dynamic setting application (e.g., changing model mid-session)
- Setting schema validation
- Config hotreload (changes without restart)
### Gap Assessment
| Component | GJC | claw-code | Gap | Complexity |
|-----------|-----|-----------|-----|------------|
| Setting Schema Definition | 300 LOC | — | 100% | Low |
| Session-Level Override | 400 LOC | — | 100% | Medium |
| Setting Propagation | 300 LOC | — | 100% | Low |
| Dynamic Application | 200 LOC | — | 100% | Medium |
| Config Hotreload | 150 LOC | — | 100% | Low |
| **Total** | **1,350 LOC** | **3,894** | **-2,544 LOC** | — |
### Proposed Implementation
**Owner Crate**: `runtime` (enhance existing `config.rs`)
**Additions to config.rs**:
- Setting schema registry
- Session setting override struct
- Setting applicator (merge global + session + override)
- Hotreload support (watch config file, signal on change)
**Size Estimate**: 500 LOC (new code, mostly schema + applicators)
---
## 7. HOOKS & PLUGINS
### GJC Behavior (gajae-code Reference)
**Source**: `packages/coding-agent/src/hooks.ts`, `packages/coding-agent/src/plugin_lifecycle.ts`
GJC provides **5 hook points**:
- `on_session_created`: After session starts
- `on_prompt_received`: Before agent loop begins
- `on_tool_use`: Before tool invocation
- `on_tool_result`: After tool completes
- `on_session_ended`: Before session cleanup
**Plugin System**:
- Plugins are shell scripts or binaries in `.claw/plugins/`
- Each plugin implements hook handlers (exit code + JSON output)
- Plugin registry stored in config
### claw-code Status
**Current**: Existing and comprehensive.
**Files**:
- `rust/crates/runtime/src/hooks.rs` (L155)
- `rust/crates/runtime/src/plugin_lifecycle.rs`
- `rust/crates/plugins/src/` (plugin manager)
**Implementation**: Hooks fully implemented; plugin system working.
### Gap Assessment
| Component | GJC | claw-code | Gap |
|-----------|-----|-----------|-----|
| Hook Points | 5 | 5 | 0% |
| Plugin Registry | ✓ | ✓ | 0% |
| Plugin Execution | ✓ | ✓ | 0% |
**Status**: **No gaps**. Hooks and plugins are fully compatible.
---
## 8. AGENTS.MD RULES & CONTEXT
### GJC Behavior (gajae-code Reference)
**Source**: gajae-code root + `docs/` (AGENTS.md files at multiple levels)
GJC loads **directory-specific rules** from `AGENTS.md` files:
- **Root AGENTS.md**: Project-level knowledge base
- **Directory AGENTS.md**: Directory-specific rules override parent
- **Rules Loaded**: Automatically prepended to system prompt during agent reasoning
- **Hierarchy**: Deepest (most specific) rules override higher level
**Rule Content**:
- Code organization and conventions
- Tool restrictions (never use X in Y context)
- Testing requirements
- Deployment/safety gates
- Architecture decisions
### claw-code Status
**Current**: Existing and matching GJC.
**Files**:
- Root: `AGENTS.md`
- Crate-level: `rust/crates/*/AGENTS.md`
- Implementation: `rust/crates/runtime/src/` (loads rules)
**Implementation**: Rules loaded and applied to prompts.
### Gap Assessment
| Component | GJC | claw-code | Gap |
|-----------|-----|-----------|-----|
| Rule Loading | ✓ | ✓ | 0% |
| Hierarchy | ✓ | ✓ | 0% |
| Prompt Integration | ✓ | ✓ | 0% |
**Status**: **No gaps**. AGENTS.md system is compatible.

|-----------|-----|-----------|-----|
| Command Parser | 800 LOC | 800 LOC | 0% |
| Spec Table (120+ entries) | 2,000 LOC | 2,000 LOC | 0% |
| Handlers (80 missing) | 3,200 LOC | 1,800 LOC | 56% |
| Help/suggestion | 600 LOC | 400 LOC | 30% |
| **Total** | **7,200 LOC** | **4,000** | **3,200 LOC** | — |
### Proposed Implementation

**New Modules**:
```
rust/crates/commands/src/
├── handlers/
│ ├── workflow.rs (/plan, /review, /approve, /ultragoal)

## 10. SUBAGENT DELEGATION & TASK EXECUTION
### GJC Behavior (gajae-code Reference)
**Source**: `packages/coding-agent/src/tools/task.ts`, `packages/coding-agent/src/task/`
GJC's **subagent system** enables parallel task execution:
- **task Tool**: Spawn parallel subtasks with independent context
- **Task States**: spawning, running, succeeded, failed
- **Task Isolation**: Each task has isolated session, permissions, context
- **Task Coordination**: `irc` tool for live inter-task communication
- **Task Monitoring**: `task.inspect`, `task.list`, `task.cancel`
- **Artifact Sharing**: Tasks share artifact URLs but not direct state
**Task Spawning**:
```json
{
"agent": "executor|architect|planner",
"tasks": [
{
"id": "task-1",
"description": "...",
"assignment": "..."
}
]
}
```
### claw-code Status
**Current**: Existing and working.
**Files**:
- `rust/crates/tools/src/lib.rs` (task tool, ~300 LOC)
- `rust/crates/runtime/src/task_*.rs` (task execution, state mgmt)
**Implementation**: Task tool works; spawning, monitoring, and coordination functional.
### Gap Assessment
| Component | GJC | claw-code | Gap |
|-----------|-----|-----------|-----|
| Task Spawning | ✓ | ✓ | 0% |
| Task Isolation | ✓ | ✓ | 0% |
| Task Monitoring | ✓ | ✓ | 0% |
| IRC Coordination | ✓ | ✓ | 0% |
**Status**: **No significant gaps**. Task execution is compatible.

### Phase 3: Polish (Settings, Commands, Integration)
**Slice 3.1: Settings & Configuration**
- Session-level setting override
- Setting schema validation
- Setting propagation to tools
- Config hotreload
**Slice 3.2: Slash Commands**
- Workflow commands (/plan, /review, /ultragoal)
- Model selection (/model set, /model list)
- Cost calculator (/cost)
- Advanced debugging (/dump, /trace)
- Task management (/tasks list, /tasks cancel)
- Theme management (/theme)

## 13. RISK & MITIGATION
| Risk | Probability | Severity | Mitigation |
|------|-------------|----------|-----------|
| SDK protocol complexity | High | High | Start with mock transport tests, iterate on real scenarios |
| Session state inconsistency | Medium | High | Comprehensive reconciliation tests, durable state verification |
| Tool compatibility gaps | Medium | Medium | Tool-by-tool comparison with GJC, shadow testing |
| Breaking changes to runtime | Medium | High | Version gates, feature flags, phased rollout |
| Performance regression | Medium | Medium | Benchmark key paths (session create, tool dispatch), profile |
---
## 14. VERIFICATION & SIGN-OFF
- [ ] SDK transport connects and communicates with mock server
- [ ] Session lifecycle operations (create, prompt, steer, abort) work end-to-end
- [ ] Tool execution with SDK matches GJC behavior
- [ ] Skill discovery finds all three scopes (bundled, project, user)
- [ ] Settings override works per-session
- [ ] Slash commands parse and dispatch correctly
- [ ] All AGENTS.md tests pass
- [ ] Hooks fire at correct lifecycle points
- [ ] Subagent tasks spawn and communicate via IRC
- [ ] Public documentation has no internal paths, hosts, or private infra
