CodeGraph (colbymchenry/codegraph) adds **multi-language strength** (20+ languages via tree-sitter), **SQLite/FTS5 indexing**, **cross-language bridging** (Swift↔ObjC, React-Native), and a **native file-watcher with debouncing**. + +**Recommendation:** Integrate CodeGraph as an **external MCP tool** (similar to RTK pattern), not by rebuilding SIN-Code's graph engine. + +--- + +## What SIN-Code Already Has + +| Component | Location | Capability | +|---|---|---| +| Symbol/Call-Graph | `cartographer.go` | PageRank-weighted symbol map, graph centrality ranking | +| Impact Analysis | `impact.go` | Blast-radius prediction (reverse dependency, affected tests) | +| Index Storage | `index_store.go`, `.sin-code/index.bin` | Persistent incremental index, trigram-based search | +| AST Extraction | `ast_provider.go`, `ast_treesitter_stub.go` | tree-sitter (optional CGO), structural fallback | +| MCP Server | `serve.go`, `--mcp` flag | Exposes tools: search, symbols, callers, callees, impact, lsp | +| Full-Text Search | Trigram index + `searchSymbols()` | Fast symbol lookup | +| LSP | `lsp_cmd.go` | Language Server Protocol implementation | + +**Assessment:** The architecture is **complete for SIN-Code's primary use case** (Go-centric, single-binary CLI agent). Multi-language symbol graphs are not the bottleneck. + +--- + +## What CodeGraph Adds (Real Differentiators) + +1. **Multi-Language Symbol Resolution** (20+ languages) + - SIN-Code: Go-zentric (uses `go list -json`), tree-sitter is opt-in/fallback + - CodeGraph: tree-sitter-first for all 20+ supported languages + - **Impact:** Better context for polyglot codebases (Go + Rust + Python + TS) + +2. **SQLite + FTS5 Backend** + - SIN-Code: gob-serialized in-memory index (trigram-based) + - CodeGraph: persistent SQL full-text search (more powerful queries, survives restarts) + - **Impact:** Query expressiveness, no memory footprint for large repos + +3. **Cross-Language Call Bridges** + - Swift ↔ ObjC, React-Native, Expo linking + - **Impact:** Useful for mobile teams; not needed for backend-only SIN-Code workflows + +4. **File-Watcher with Debounce & Staleness UI** + - SIN-Code: Refresh is manual (`sin-code index` command) or implicit on agent spawn + - CodeGraph: inotify/FSEvents with configurable debounce, staleness banner + - **Impact:** Better DX for IDE integration + Claude Code/Cursor + +5. **MCP-First Design** + - CodeGraph is built to serve **other agents** (Claude Code, Cursor, etc.) + - SIN-Code **is** the agent; it consumes its own graph + - **Impact:** Different distribution model; CodeGraph shines as a shared service + +--- + +## Integration Options + +### Option A: CodeGraph as External MCP Tool (Recommended) +- **What:** Register CodeGraph as an MCP preset (like RTK was registered as a binary) +- **How:** + 1. `sin-code codegraph install` fetches the binary from https://github.com/colbymchenry/codegraph/releases + 2. SIN-Code's own MCP server adds a proxy tool `codegraph:explore` → calls the external service + 3. Callers can request symbol/impact data from CodeGraph for all 20+ languages; SIN-Code's Go-specific tools remain +- **Upsides:** Zero duplication, automatic multi-language support, clean separation +- **Downsides:** Requires CodeGraph binary to be running; network latency if served over HTTP +- **Effort:** ~200 lines: install command + MCP proxy tool + config + +### Option B: Enhanced SIN-Code Index (Moderate) +- **What:** Improve the existing `index` + `cartographer` to use SQLite/FTS5 + tree-sitter-first +- **How:** + 1. Add optional SQLite backend to `index_store.go` (keep gob as fallback) + 2. Promote tree-sitter from CGO-optional to default (requires Go 1.22+ and tree-sitter C headers) + 3. Add native fsnotify-based auto-watcher + 4. Extend cartographer to rank multi-language symbols uniformly +- **Upsides:** Single unified graph, no external dependency, better FTS5 queries +- **Downsides:** Complex migration, tree-sitter requires C build deps, longer compilation +- **Effort:** ~800 lines; touches index_store, cartographer, ast_provider, watch subsystem + +### Option C: Hybrid (Best Long-Term, Complex) +- **What:** SIN-Code has a Go-fast path (current index); CodeGraph for multi-language exploration +- **How:** + 1. Keep SIN-Code's Go-optimized index for speed + 2. Add CodeGraph as optional MCP tool for multi-language exploration + 3. Cache CodeGraph results locally; use for impact analysis when needed +- **Upsides:** Fast Go path, extensible to other languages +- **Downsides:** Two graph systems, consistency issues, cache invalidation +- **Effort:** ~600 lines; complex integration + +### Option D: Do Nothing +- **What:** Status quo +- **Why:** Current graph is sufficient for SIN-Code's primary workflows (Go agents, local code context) +- **When to revisit:** If you're targeting polyglot teams or integrating with Claude Code/Cursor as a shared service + +--- + +## Recommended Path: Option A + +**Rationale:** +- Zero risk of duplication (external binary, MCP interface) +- RTK pattern is already proven in SIN-Code +- CodeGraph's multi-language + FTS5 benefits flow naturally to agents without major refactoring +- Low effort (~200 lines), high value + +**Implementation Sketch:** + +```go +// cmd/sin-code/codegraph_cmd.go (new) +func newCodeGraphInstallCmd() *cobra.Command { + // Downloads codegraph binary from https://github.com/colbymchenry/codegraph/releases + // Stores in ~/.local/bin or custom config path + // Verifies with `codegraph --version` +} + +// internal/serve.go (addition) +// Add MCP tool proxy: +// { +// name: "codegraph:explore", +// description: "Multi-language code graph (tree-sitter, 20+ langs, SQLite/FTS5)", +// inputSchema: { queries, languages, limits }, +// impl: forwards to external codegraph MCP server +// } + +// internal/orchestrator/cartographer.go (minimal change) +// When impact/callers/callees is requested for non-Go: +// - if CodeGraph binary available: delegate via MCP proxy +// - else: fall back to Go-specific analysis +``` + +**Next Steps:** +1.

Changes produce new instances, enabling clean versioning. + +4. **Non-Breaking**: Spec Layer is opt-in. Existing Agent Loop workflows continue unchanged. + +5. **Lightweight**: Only stdlib dependencies (no heavy frameworks).

markdown-based specification system +for encoding all project requirements, architecture decisions, and quality gates. + +### Design Principles + +1. **Deterministic**: No LLM calls or randomness. All operations are synchronous + and produce identical output for identical input. + +2. **Markdown-first**: Specs are stored as markdown + JSON metadata. Human-readable + and version-control friendly. + +3. **Immutable semantics**: Specs are never edited in-place. Mutations produce new + Spec instances, enabling clean versioning and rollback. + +4. **Non-breaking**: The Spec Layer is an additive feature. Existing Agent Loop + workflows continue unchanged. Specs are "opt-in" enhancements. + +5. **Lightweight**: No external dependencies beyond stdlib. Compiles to a small + binary footprint. + +### Core Components + +#### types.go +- `Spec`: Core immutable spec container +- `SpecKind`: Enum for spec types (goal, process, constraint, component, integration) +- `SpecStatus`: Lifecycle states (draft, active, archived) +- `SpecCollection`: Set of related specs with dependency graph +- `DependencyGraph`: Directed acyclic graph (DAG) of spec dependencies + +#### validate.go +- `ValidateSpec()`: Check single spec for required fields, markdown syntax +- `ValidateDependencies()`: Detect cycles, missing references in collection +- `ValidateTokenBudget()`: Ensure total token estimate stays within budget + +#### merge.go +- `MergeSpecs()`: Three-way merge of specs (base, ours, theirs) +- `MergeStrategy`: Enum for conflict resolution (ours, theirs, newest, manual) +- `MergeConflict`: Field-level conflict details +- `MergeResult`: Merge outcome with resolved/unresolved conflicts + +#### compiler.go (Phase 2) +- `CompileSpec()`: Validate and prepare spec for execution +- `DependencyGraph`: Build topological sort of specs +- `ComputeMetadata()`: Calculate static metadata (depth, hash) + +#### gates.go (Phase 3) +- `Gate`: Abstract quality gate interface +- `TokenBudgetGate`: Verify token estimates +- `MarkdownSyntaxGate`: Check markdown formatting +- `DependencyGate`: Verify DAG structure + +#### metaspec.go (Phase 4) +- `MetaSpec`: Compressed spec index for token optimization +- `SpecIndexer`: Build searchable index of specs +- `TokenBudgeter`: Allocate token budgets across specs + +### Usage Example + +```go +// Create spec +s := spec.NewSpec("spec_auth_001", "User Authentication System", spec.SpecKindGoal) +s.Description = "# Auth System\n..." +s.Goals = "- Support email+password
