Intent +Refocus AI Code Graph into a **high-signal / low-token** code navigation layer for LLM agents working on .NET repos. + +Primary value proposition: **fast, semantically correct context reconstruction** (call graph + complexity + coupling + dead-code) with minimal output. + +## 1) Problem +LLMs are slow and token-expensive when they have to discover: +- where code lives (structure), +- what depends on what (call graph + interface dispatch), +- what is risky to change (impact, coupling), +- what is worth refactoring (hotspots), +- what can be deleted safely (dead-code). + +Pure grep/read exploration is: +- O(N) tool calls, +- noisy (false positives), +- not semantically aware (interface dispatch, overrides), +- very expensive in tokens. + +## 2) Goals (next milestone) +### G1 — Token economy as default +- Provide `--compact` output across the CLI. +- Make compact mode the default for agent-facing commands (`context`, `impact`, `callgraph`, `hotspots`, `dead-code`, `coupling`). + +### G2 — Make the “agent flow” effortless +- A single recommended workflow: analyze → context → impact/callgraph. +- Clear docs for agent integration. + +### G3 — Keep only high-leverage features in the default pipeline +- Make weaker features optional (hash-only semantic search / token-search). +- Ensure the default stages maximize signal-per-token. + +### G4 — Reliability & staleness detection +- Make it obvious when the db is out-of-date. +- Provide a cheap staleness check (commit hash + file timestamps). + +## 3) Non-goals (this milestone) +- Multi-repo / monorepo federation. +- Runtime tracing. +- Cloud-only dependency (keep local-first). +- Perfect semantic search quality (optional stage). + +## 4) Scope / Deliverables +### D1 — Output contract: compact-first +- Add `--format compact|table|json|csv` where applicable. +- `compact` rules: + - one line per row item + - stable identifiers + - no ASCII tables + - bounded lists (top N + “...”) with `--top` / `--max-items` + +### D2 — Method identity & selection +- Consistent, stable `MethodId` in outputs. +- Allow selecting a method by: + - exact fully qualified signature, + - substring match, + - `--id `. + +### D3 — Staleness metadata +- Store analysis metadata in DB: + - analyzedAt + - solution path + - git commit hash (if available) + - tool version +- Add `ai-code-graph status` (or `ai-code-graph db-info`) that prints: + - whether db looks stale + - what solution it was built from + - last analyzed timestamp + +### D4 — Feature gating / pipeline slimming +- Introduce a simple stage selector: + - `ai-code-graph analyze ... --stages core` (default) + - `--stages full` (includes optional stages) +- `core` stages should include: extract, callgraph, metrics, (optional) hash-embed only if required by duplicates/clusters. +- Optional stages: token-search/semantic-search improvements. + +### D5 — Documentation refresh +- Add a “LLM quickstart” doc focused on minimal context. +- Keep README short; move deep docs to `docs/`. + +## 5) User Stories +1. As an LLM agent, I can run `context` and get a small, deterministic summary for a method before editing. +2. As an engineer, I can quickly identify the riskiest modules (coupling/instability) before introducing changes. +3. As an engineer, I can identify top complexity hotspots without reading the entire repo. +4. As an engineer, I can spot likely dead code safely. +5. As an LLM agent, I can detect staleness and avoid using outdated graphs. + +## 6) Acceptance Criteria +- `context` output in compact mode is <= ~25 lines for typical methods. +- `hotspots`, `dead-code`, `coupling` have bounded outputs by default. +- `db-info/status` clearly indicates when db is likely stale. +- CLI help documents compact mode and recommended flows. +- No regression in existing command names/options without a compatibility note. + +## 7) Risks +- Refactoring CLI output may break scripts → mitigate with `--format json` stability. +- Staleness heuristics can produce false positives → provide “best-effort” and clear messaging. + +## 8) Notes +This PRD intentionally optimizes for **signal-per-token**. If a feature does not improve signal-per-token, it should be optional. diff --git a/.taskmaster/tasks/task_001.md b/.taskmaster/tasks/task_001.md new file mode 100644 index 0000000..86a1b4b --- /dev/null +++ b/.taskmaster/tasks/task_001.md @@ -0,0 +1,153 @@ +# Task ID: 1 + +**Title:** Initialize .NET Solution and Project Structure + +**Status:** done + +**Dependencies:** None + +**Priority:** high + +**Description:** Create the .NET solution with a CLI tool project (global tool), a core library project for analysis logic, and a test project.

Implement `LoadSolutionAsync`: + ```csharp + public async Task LoadSolutionAsync(string solutionPath, CancellationToken ct) + { + EnsureMSBuildRegistered(); + _workspace = MSBuildWorkspace.Create(); + var solution = await _workspace.OpenSolutionAsync(solutionPath, ct); + + var compilations = new Dictionary(); + var diagnostics = new List(); + + foreach (var project in solution.Projects) + { + ct.ThrowIfCancellationRequested(); + var compilation = await project.GetCompilationAsync(ct); + if (compilation != null) + compilations[project.Id] = compilation; + } + + return new LoadedWorkspace(solution, compilations.AsReadOnly(), diagnostics.AsReadOnly()); + } + ``` + +2. Handle the workspace's `WorkspaceFailed` event to capture MSBuild diagnostic messages during solution load. + +3. Validate the solution path exists before attempting to open (throw `FileNotFoundException` with clear message). + +4. Ensure proper disposal of MSBuildWorkspace in the `Dispose` method. + +5.

Wrap individual project compilation in try-catch: + ```csharp + foreach (var project in solution.Projects) + { + try + { + var compilation = await project.GetCompilationAsync(ct); + if (compilation != null) + { + // Check for critical compilation errors + var errors = compilation.GetDiagnostics() + .Where(d => d.Severity == DiagnosticSeverity.Error) + .ToList(); + if (errors.Any()) + diagnostics.Add(new WorkspaceDiagnostic(...)); + compilations[project.Id] = compilation; + } + } + catch (Exception ex) + { + diagnostics.Add(new WorkspaceDiagnostic( + WorkspaceDiagnosticKind.Failure, + $"Failed to compile {project.Name}: {ex.Message}", + project.Name + )); + } + } + ``` + +3. Define `WorkspaceDiagnostic` record: + ```csharp + public record WorkspaceDiagnostic( + WorkspaceDiagnosticKind Kind, + string Message, + string? ProjectName + ); + ``` + +4.

Please specify one explicitly."); + dir = dir.Parent; + } + return null; + } + } + ``` + +2. Handle edge cases: + - Multiple .sln files in same directory: throw with helpful message listing found files + - Traversal stops at filesystem root + - Symlinks and junctions should be followed normally + +3. Integrate with WorkspaceLoader: add an overload or modify `LoadSolutionAsync` to accept nullable path and use auto-discovery when null. + +### 2.5. Add Progress Reporting and Cancellation Token Support + +**Status:** done +**Dependencies:** 2.2, 2.3 + +Implement IProgress based progress reporting for solution loading and compilation phases, and ensure CancellationToken is properly threaded through all async operations to support responsive cancellation of long-running solution loads. + +**Details:** + +1. Define a progress reporting model: + ```csharp + public record WorkspaceLoadProgress( + string Phase, // "Loading", "Compiling", "Complete" + string? ProjectName, + int CurrentProject, + int TotalProjects + ); + ``` + +2. Add `IProgress?` parameter to `LoadSolutionAsync`: + ```csharp + public async Task LoadSolutionAsync( + string solutionPath, + IProgress? progress = null, + CancellationToken ct = default) + ``` + +3. Report progress at key points: + - After solution is opened: report total project count + - Before each project compilation: report project name and index + - After all compilations: report completion + ```csharp + progress?.Report(new WorkspaceLoadProgress( + "Compiling", project.Name, index + 1, totalProjects)); + ``` + +4. Ensure CancellationToken is passed to: + - `OpenSolutionAsync(solutionPath, ct)` + - `project.GetCompilationAsync(ct)` + - Checked between project iterations: `ct.ThrowIfCancellationRequested()` + +5. Add a console-friendly progress reporter implementation for CLI usage: + ```csharp + public class ConsoleProgressReporter : IProgress + { + public void Report(WorkspaceLoadProgress value) + { + Console.WriteLine($"[{value.CurrentProject}/{value.TotalProjects}] {value.Phase}: {value.ProjectName}"); + } + } + ``` diff --git a/.taskmaster/tasks/task_003.md b/.taskmaster/tasks/task_003.md new file mode 100644 index 0000000..c1b5f3b --- /dev/null +++ b/.taskmaster/tasks/task_003.md @@ -0,0 +1,265 @@ +# Task ID: 3 + +**Title:** Implement Code Model Extractor + +**Status:** done + +**Dependencies:** 2 ✓ + +**Priority:** high + +**Description:** Extract the full structural hierarchy from Roslyn compilations: Projects → Namespaces → Types (classes, interfaces, records, structs) → Methods.

Place all types in a `CallGraph` namespace/folder within the Core project. + +### 5.2. Implement syntax node location for method declarations + +**Status:** done +**Dependencies:** 5.1 + +Map each MethodModel from the code model back to its corresponding SyntaxNode (MethodDeclarationSyntax, ConstructorDeclarationSyntax, etc.) using the Roslyn SemanticModel to enable body analysis. + +**Details:** + +1. For each project in the code model, get the corresponding `Compilation` from LoadedWorkspace. +2. For each MethodModel, reconstruct the lookup path: use the fully-qualified name and parameter types to locate the `IMethodSymbol` via `Compilation.GetTypeByMetadataName()` then `.GetMembers()`. +3. Handle all method-like declarations: `MethodDeclarationSyntax`, `ConstructorDeclarationSyntax`, `DestructorDeclarationSyntax`, `OperatorDeclarationSyntax`, `ConversionOperatorDeclarationSyntax`, `AccessorDeclarationSyntax` (property getters/setters), and `LocalFunctionStatementSyntax`. +4. Handle expression-bodied members (`ArrowExpressionClauseSyntax`) which don't have a Block body but still contain invocable expressions. +5. Handle partial methods by combining declarations across syntax trees. +6. Cache the mapping `Dictionary` for reuse during invocation resolution. +7. Handle generic method instantiations by mapping back to the `OriginalDefinition` or `ReducedFrom` symbol. +8. Log warnings for MethodModels that cannot be resolved (e.g., generated code, missing references). + +### 5.3. Implement InvocationExpression resolution for direct method calls + +**Status:** done +**Dependencies:** 5.2 + +Walk method bodies to find InvocationExpressionSyntax nodes, use SemanticModel.GetSymbolInfo() to resolve targets, and map resolved IMethodSymbols back to MethodModel IDs for direct call edges. + +**Details:** + +1. For each resolved method SyntaxNode, get all descendant `InvocationExpressionSyntax` nodes from the body (Block or ArrowExpressionClause). +2. For each invocation, call `semanticModel.GetSymbolInfo(invocation)` to get the resolved symbol. +3. Handle `SymbolInfo.Symbol` (resolved) vs `SymbolInfo.CandidateSymbols` (ambiguous/overloaded) - for candidates, add edges to all candidate methods within the solution. +4. Map the resolved `IMethodSymbol` back to a MethodModel ID: + - Use `OriginalDefinition` to handle generic instantiations (e.g., `List.Add` → `List.Add`) + - Use `ReducedFrom` to handle extension method calls resolved to their static form + - Build a reverse lookup `Dictionary` using SymbolEqualityComparer.Default +5. Skip methods where the resolved symbol belongs to assemblies outside the solution (external calls) - log these at Debug level. +6. Create edges with `CallKind.Direct` for standard resolved invocations. +7. Handle chained method calls (fluent APIs) where each `.Method()` in a chain is a separate invocation. +8. Handle `nameof()` expressions - these are NOT invocations and should be skipped. + +### 5.4. Handle ObjectCreationExpression as constructor calls and member access patterns + +**Status:** done +**Dependencies:** 5.2 + +Resolve ObjectCreationExpression (new T()), ImplicitObjectCreationExpression (new()), and base/this constructor initializers as constructor call edges. + +**Details:** + +1. Find all `ObjectCreationExpressionSyntax` nodes in method bodies. +2. Use `semanticModel.GetSymbolInfo(objectCreation)` to resolve the constructor `IMethodSymbol`. +3. Handle `ImplicitObjectCreationExpressionSyntax` (target-typed `new()`) which requires type inference from context. +4. Handle `BaseConstructorInitializerSyntax` (`: base(...)`) and `ThisConstructorInitializerSyntax` (`: this(...)`) in constructor declarations. +5. Create edges with `CallKind.Constructor`. +6. Handle object initializer expressions - property setters in `{ Prop = value }` may invoke property setters which are method-like. +7. Handle collection initializer expressions which invoke `.Add()` methods implicitly. +8. Handle array creation expressions (`new int[] { ... }`) - these don't invoke constructors but should be recognized and skipped. +9. Map resolved constructor IMethodSymbols back to MethodModel IDs using the same reverse lookup from subtask 3. +10. Handle `Activator.CreateInstance()` and similar reflection-based construction - log as unresolvable. + +### 5.5. Implement interface dispatch resolution + +**Status:** done +**Dependencies:** 5.3 + +Build an interface-to-implementation mapping from the code model's TypeImplements data and resolve interface method calls to all known implementing methods. + +**Details:** + +1. Pre-build an interface implementation map from the code model: + - For each TypeModel with `ImplementedInterfaces`, map interface method IDs to the implementing type's corresponding method IDs. + - Handle explicit interface implementations (e.g., `IFoo.Bar()`) which have different naming patterns. + - Handle implicit interface implementations where the method name matches. +2. When an invocation resolves to an `IMethodSymbol` where `ContainingType.TypeKind == TypeKind.Interface`: + - Create an edge with `CallKind.Interface` to the interface method itself. + - Look up all known implementations from the pre-built map. + - Create additional edges with `CallKind.Interface` to each implementation. +3. Handle generic interface implementations (e.g., `IComparable`) by matching on the unbound generic interface. +4. Handle interface inheritance chains (e.g., `IFoo : IBar` where IBar.Method is called but implemented in a class implementing IFoo). +5. Handle cases where the implementation map is incomplete (abstract classes implementing only some interface methods) - log these. +6. Store the interface map in CallGraphBuilder for reuse across all method bodies. + +### 5.6. Handle virtual/override dispatch and delegate invocations + +**Status:** done +**Dependencies:** 5.3 + +Resolve virtual and override method calls to all possible dispatch targets in the type hierarchy, and handle delegate/event invocations including Func<>/Action<> types. + +**Details:** + +1. **Virtual/Override dispatch:** + - When invocation resolves to a virtual/abstract method (`IMethodSymbol.IsVirtual || IsAbstract || IsOverride`): + - Create edge with `CallKind.Virtual` to the declared method. + - Walk the type hierarchy to find all overrides: use `IMethodSymbol.OverriddenMethod` chain upward and find all types that override it downward. + - Build override lookup: for each type in the solution, check if it overrides the target method. + - Create edges to each override with `CallKind.Virtual`. + - Handle `base.Method()` calls which bypass virtual dispatch - these should be `CallKind.Direct` to the specific base implementation. +2. **Delegate invocations:** + - Detect delegate invocations: `delegateVariable(args)` or `delegateVariable.Invoke(args)` patterns. + - For typed delegates (Func<>, Action<>, custom delegate types), the target is generally unknown at static analysis time. + - When the delegate is assigned from a method group in the same method/class, resolve the target. + - Handle event invocations (`EventName?.Invoke(...)`) - mark as `CallKind.Delegate`. + - Track delegate assignments via `+=` to identify potential targets for events. +3. Handle `sealed` override methods - these don't need further dispatch resolution. + +### 5.7. Handle LINQ expressions, lambda invocations, and edge cases + +**Status:** done +**Dependencies:** 5.3, 5.4, 5.5, 5.6 + +Resolve LINQ method chain calls (Select, Where, etc.), lambda/anonymous method invocations, extension methods, operator overloads, and conditional access patterns (?.). + +**Details:** + +1. **LINQ and extension methods:** + - LINQ query syntax (`from x in y select z`) is lowered to method calls - find the underlying `InvocationExpressionSyntax` nodes generated by the compiler or use `GetSymbolInfo()` on query clause syntax nodes. + - LINQ method syntax (`.Where().Select()`) is already handled as chained invocations, but ensure extension method resolution uses `ReducedFrom` to map back to the static extension method definition. + - Handle custom extension methods defined in the solution. +2. **Lambda and anonymous methods:** + - Lambdas passed as arguments (e.g., `.Where(x => x.IsValid())`) contain invocations within their bodies. + - Recursively walk lambda bodies (`LambdaExpressionSyntax`, `AnonymousMethodExpressionSyntax`) for invocations. + - Attribute the discovered calls to the containing method (the lambda's enclosing method). +3. **Conditional access (`?.`):** + - `ConditionalAccessExpressionSyntax` wraps invocations differently: the method call is inside a `MemberBindingExpressionSyntax`. + - Use `GetSymbolInfo()` on the overall conditional access to resolve the target. +4. **Operator overloads:** + - Binary/unary operator expressions may resolve to user-defined operator methods. + - Check `semanticModel.GetSymbolInfo(binaryExpression)` for operator overloads defined in solution types. + - Create edges with `CallKind.Operator` (add to CallKind enum if needed, otherwise use Direct). +5. **Implicit conversions:** + - User-defined implicit/explicit conversion operators invoked implicitly in assignments or casts. + - Use `GetConversion()` or `GetSymbolInfo()` on cast expressions. +6. **Pattern matching invocations:** Handle `is` patterns that invoke `Deconstruct` methods. diff --git a/.taskmaster/tasks/task_006.md b/.taskmaster/tasks/task_006.md new file mode 100644 index 0000000..1dd7346 --- /dev/null +++ b/.taskmaster/tasks/task_006.md @@ -0,0 +1,172 @@ +# Task ID: 6 + +**Title:** Implement Cognitive Complexity Metrics Engine + +**Status:** done + +**Dependencies:** 2 ✓, 3 ✓ + +**Priority:** high + +**Description:** Compute cognitive complexity, lines of code, and nesting depth for each method.

To handle this: use a `HashSet<(string, string)>` as the accumulator instead of a plain List, or add a deduplication step before returning. The final return should convert to `List<(string, string)>`. The simplest approach is to use a HashSet during accumulation: `var seen = new HashSet<(string, string)>()` and only add to results if `seen.Add((caller, callee))` returns true.

InvalidateVectorCache removes an entry by normalized path. Use `private static readonly Dictionary _vectorIndexCache = new();` and `private static readonly object _cacheLock = new();`.

For caching to work correctly, cache the full index (all embeddings) and filter results after search instead, or use a cache key that includes the exclusion. The simpler approach is to cache the full index and just exclude the target from results. Update the search call to request top+1 results and filter out the target method from the results list. + +### 22.3.

(2) Recall test: generate 200+ random 384-d vectors, for each vector compute true neighbors via brute-force cosine distance within epsilon, then compute LSH candidates and verify recall >= 0.8 (at least 80% of true neighbors found). (3) Edge cases: single vector returns empty neighbors, all-identical vectors are all candidates for each other, orthogonal vectors are not candidates. (4) Performance benchmark: generate 1000+ random vectors, time the brute-force O(n^2) neighbor computation vs LSH-backed computation, assert LSH is faster (use Stopwatch). (5) Integration test: run IntentClusterer with LSH on a fixture and compare cluster output to brute-force clustering, allowing tolerance for approximate results (e.g., >= 90% agreement on cluster assignments). diff --git a/.taskmaster/tasks/task_050.md b/.taskmaster/tasks/task_050.md new file mode 100644 index 0000000..0001283 --- /dev/null +++ b/.taskmaster/tasks/task_050.md @@ -0,0 +1,190 @@ +# Task ID: 50 + +**Title:** Full Dependency Injection Container Setup + +**Status:** done + +**Dependencies:** 27 ✓, 42 ✓, 43 ✓, 44 ✓ + +**Priority:** medium + +**Description:** Wire all services using Microsoft.Extensions.DependencyInjection (already imported but unused), with configurable IEmbeddingEngine registration and service resolution in command actions. + +**Details:** + +Create new file: AiCodeGraph.Core/DI/ServiceRegistration.cs + +```csharp +using Microsoft.Extensions.DependencyInjection; +using AiCodeGraph.Core.Storage; +using AiCodeGraph.Core.Embeddings; +using AiCodeGraph.Core.Metrics; +using AiCodeGraph.Core.CallGraph; +using AiCodeGraph.Core.Normalization; +using AiCodeGraph.Core.Duplicates; +using AiCodeGraph.Core.Drift; + +namespace AiCodeGraph.Core.DI; + +public static class ServiceRegistration +{ + public static IServiceCollection AddAiCodeGraph(this IServiceCollection services, Action? configure = null) + { + var options = new AiCodeGraphOptions(); + configure?.Invoke(options); + + // Storage - scoped (one per command invocation) + services.AddScoped(sp => + { + var storage = new StorageService(options.DatabasePath); + return storage; + }); + + // Embedding engine - configurable + services.AddSingleton(sp => + { + return options.EmbeddingEngine switch + { + "openai" => new OpenAiEmbeddingEngine( + options.OpenAiApiKey ??

But: -- Cannot compute instability ratios across the entire codebase in one pass -- Cannot determine abstractness (interface-to-concrete ratio) without reading every type -- Cannot calculate distance from main sequence at all - -**Real output example:** -``` -AiCodeGraph.Core.Storage Ca=14, Ce=0, I=0.00 ← Very stable, many dependents -AiCodeGraph.Core.Embeddings Ca=10, Ce=0, I=0.00 ← Also stable -AiCodeGraph.Tests Ca=0, Ce=15, I=1.00 ← Fully unstable (normal for tests) -``` - -**Why it matters for AI-assisted development:** When the AI needs to decide where to place new code, coupling metrics answer "which modules are stable (don't touch) vs. volatile (safe to modify)" objectively. Without this, the AI relies on heuristics like "this folder has more files so it's probably important." - -**Verdict:** No AI workflow can replicate this. The computation requires full Roslyn semantic analysis. - ---- - -### 2. `cg:hotspots` — IRREPLACEABLE - -**What it provides:** Cognitive complexity (CC), lines of code (LOC), and max nesting depth for every method, ranked. - -**What the AI can do instead:** Read a method and estimate "this looks complex." But: -- Cannot compute cognitive complexity scores (requires AST walking with specific increment rules) -- Cannot rank all methods across the codebase — would need to read every file -- Even if it read every file, the estimate would be subjective - -**Real output example:** -``` -McpServer.HandleToolCall CC=59 LOC=120 Nest=6 ← Extreme complexity -IntentClusterer.Dbscan CC=23 LOC=37 Nest=5 ← High complexity in compact code -MetricsEngine.ComputeMetrics CC=18 LOC=38 Nest=3 ← Moderate -``` - -**Why it matters:** An AI planning a refactor can immediately identify the top candidates without reading 50 files. The CC score is an objective, repeatable metric — not "I think this is complex." - -**Verdict:** Irreplaceable. Cognitive complexity computation requires Roslyn AST analysis that cannot be approximated from text. - ---- - -### 3. `cg:dead-code` — IRREPLACEABLE - -**What it provides:** All methods with zero callers in the call graph. - -**What the AI can do instead:** Grep for a specific method name to check if it's called. But: -- Grep is reactive (must know what to search for), dead-code is proactive -- Grep finds text matches, not semantic calls (matches in comments, strings, similar names) -- Grep cannot handle interface dispatch (`IFoo.Bar()` calling `FooImpl.Bar()`) -- To check the entire codebase, the AI would need to grep every method individually - -**Real output:** Found 49 potentially unreachable methods in one call. - -**Why it matters:** During refactoring, dead code identification prevents wasted effort on unused code paths. The AI would otherwise maintain and modify dead code unknowingly. - -**Verdict:** Irreplaceable. Proactive identification of unreachable code requires a complete call graph with semantic resolution. - ---- - -### 4. `cg:context` — FASTER (5x fewer tool calls) - -**What it provides:** In one call: method complexity, direct callers, direct callees, cluster membership, and known duplicates. - -**What the AI can do instead:** The same information via: -1. `Read` the file containing the method -2. `Grep` for callers (by method name) -3. `Read` the method body to identify callees -4. Cross-reference with other methods for duplicates - -That's 4-6 tool calls producing ~200-500 lines of context. `cg:context` produces the same in 1 call with ~20 lines. - -**Why it matters:** Before editing any method, the AI needs to understand its context. `cg:context` is the optimal pre-edit ritual — minimal context window usage, maximum information density. - -**Limitation:** Only provides summaries. If the AI needs to read the actual implementation of a caller, it still needs `Read`. - -**Verdict:** Same information, dramatically fewer round-trips. Most valuable in large codebases where each Grep returns dozens of results. - ---- - -### 5. `cg:tree` — FASTER (for initial orientation) - -**What it provides:** Complete project → namespace → type → method hierarchy with signatures. - -**What the AI can do instead:** -1. `Glob **/*.cs` to find all files -2. `Read` key files to understand structure -3. Mentally construct the hierarchy - -In a 50-file project, this takes 5-10 tool calls. In a 500-file project, it's impractical. - -**Comparative speed:** -- `cg:tree`: 1 call, complete result -- Explore agent: 5-15 calls, partial result (only files read) - -**Limitation:** Shows the snapshot from last `analyze`. If code changed since, the tree is stale. The AI's Explore agent always sees current code. - -**Verdict:** Best for first-time orientation. In actively changing code, supplement with direct reads. - ---- - -### 6. `cg:impact` — FASTER (for transitive analysis) - -**What it provides:** All methods transitively affected by changing a given method (callers of callers of callers...). - -**What the AI can do instead:** -1. Grep for direct callers of method X -2. For each caller found, grep for its callers -3. Repeat until no new callers found - -This is O(n) grep calls where n = depth of call chain. Each grep may return false positives (text matches that aren't actual calls). - -**Additional advantage:** `cg:impact` uses Roslyn's semantic model, so it correctly resolves: -- Interface implementations (`IService.Do()` → `ServiceImpl.Do()`) -- Virtual method overrides -- Implicit conversions and operator overloads - -**Limitation:** In this small codebase, impact shows only 1 affected method for most queries. The value scales with codebase size. - -**Verdict:** Essential for large codebases. For small projects, Grep is sufficient. - ---- - -### 7. `cg:clusters` — COMPARABLE (algorithmic vs intuitive) - -**What it provides:** DBSCAN-based grouping of methods with similar structural signatures and semantic payloads. Includes cohesion scores. - -**What the AI can do instead:** After reading multiple files, recognize patterns like "these 5 methods all follow the same template." But: -- Only for files already read (not cross-codebase) -- Cannot compute cohesion scores -- May miss non-obvious groupings - -**Real output quality:** Mixed. -- Good: `dispose operations` (cohesion: 1.00) — objectively correct -- Good: `visit/statement operations` (cohesion: 0.65) — recognized the Visitor pattern -- Mediocre: `save/method operations` (cohesion: 0.57) — vague label, 26 heterogeneous members - -**Why it matters:** During refactoring, clusters answer "which methods should move together?" and "is this class doing too many things?" (low cohesion clusters spanning multiple types). - -**Verdict:** Provides insights the AI might miss, especially cross-class similarities. But labels need human interpretation — they're generated from method name tokens, not understanding. - ---- - -### 8. `cg:similar` — COMPARABLE (limited by embedding quality) - -**What it provides:** Methods ranked by vector similarity to a target method. - -**What the AI can do instead:** Read the target method, then search for methods with similar parameter types, return types, or naming patterns. - -**Real output quality:** -``` -IntentClusterer.ClusterMethods → similar to: - 0.42 CouplingAnalyzer.AnalyzeAsync ← same "process list, return results" pattern - 0.42 IntentClusterer.GenerateLabel ← same class, related logic - 0.37 HybridScorer.Merge ← similar data transformation -``` - -These are reasonable but not revelatory. An AI reading those methods would likely notice the same similarities. - -**Limitation:** With hash-based embeddings (no ML model), similarity is based on token overlap in signatures and payloads. True semantic similarity (understanding what the method does) requires LLM embeddings. - -**Verdict:** Useful for discovering candidates for shared abstractions. The AI could find the same patterns with more effort, but `similar` surfaces them proactively. - ---- - -### 9. `cg:token-search` — AI IS BETTER - -**What it provides:** Ranked list of methods matching a natural-language query, using hash-embedding cosine similarity. - -**What the AI can do instead:** Parse the query intent, construct appropriate regex patterns, iterate on search results. - -**Empirical comparison — query: "detect duplicates clone"** - -Token-search results (top 3): -``` -0.44 DetectClones_EmptyInput_ReturnsEmpty() ← test method, not the implementation -0.44 DetectClones_EmptyInput_ReturnsEmpty() ← duplicate result from different class -0.32 DetectClones_SingleMethod_ReturnsEmpty() ← another test -``` - -Grep results (`detect.*clone|clone.*detect`): -``` -StructuralCloneDetector.cs: var structuralClones = structuralDetector.DetectClones(...) -SemanticCloneDetector.cs: var semanticClones = semanticDetector.DetectClones(...) -Program.cs: static async Task DetectDuplicatesStage(...) -``` - -Grep immediately finds the production implementations. Token-search surfaces tests first. - -**Why token-search loses:** Hash-based embeddings don't understand semantics. They tokenize method names and compute bag-of-words similarity. The AI understands that "detect duplicates" means the implementation, not the tests. - -**Verdict:** Inferior to AI's Grep + reasoning. The AI can adapt its search strategy based on results; token-search cannot. - ---- - -### 10. `cg:semantic-search` — DEPENDS ON CONFIGURATION - -**Without LLM embeddings (hash-only):** Equivalent to token-search. Same limitations apply. - -**With LLM embeddings (OpenAI/ONNX):** Potentially superior to both grep and token-search, because it could understand "methods that persist data" → `SaveMetricsAsync`, `SaveCallGraphAsync`, even if the query words don't appear in the method name. - -**Current state:** This codebase uses hash embeddings (384-dim feature hashing, no ML model). Semantic search provides no advantage over grep. - -**Verdict:** Only valuable with real LLM embeddings configured. Without them, skip it. - ---- - -## Recommendations for AI Agent Workflows - -### Before editing a method: -``` -cg:context → 1 call, full picture -``` -Replaces: Read file + Grep callers + Grep callees + assess complexity (4-6 calls) - -### Before planning a refactor: -``` -cg:hotspots → What to refactor (ranked by complexity) -cg:coupling → What's safe to change (high instability = safe) -cg:dead-code → What to delete -cg:clusters → What should move together -``` -The AI cannot replicate any of these with Grep/Read alone. - -### Before assessing change risk: -``` -cg:impact → What breaks if this changes -``` -Replaces: Recursive grep for callers (3-5 rounds, missing interface dispatch) - -### For finding code (use AI's native tools instead): -``` -Grep + Explore agent → Better than token-search -Read + reasoning → Better than similar (for small scope) -``` - -### For first-time codebase orientation: -``` -cg:tree → Fastest structural overview -cg:hotspots → Where the complexity lives -cg:coupling → Which modules are stable vs volatile -``` -This trio in 3 calls gives more architectural insight than 20 rounds of Explore agent. - ---- - -## When to Rebuild the Graph - -The graph is a snapshot. It becomes stale when: -- New methods are added (not in tree, not in dead-code analysis) -- Method signatures change (impact analysis is wrong) -- New call relationships exist (callgraph is incomplete) - -Rule of thumb: rebuild after any structural change (new classes, moved methods, changed signatures). Don't rebuild for internal logic changes within existing method bodies — complexity metrics update, but the call graph doesn't change. - ---- - -## Conclusion - -Pre-computed code graph tools and AI agent capabilities are **complementary, not competing**: - -- **Code graph tools excel at:** Global metrics (coupling, complexity, reachability), pre-computed relationships (call graph, clones), and architectural views (tree, clusters). -- **AI agent excels at:** Understanding intent, adaptive search, reading and reasoning about implementation details, handling novel queries. - -The optimal workflow uses both: code graph tools for architectural context and objective metrics, AI agent tools for precise code understanding and implementation work. Removing either degrades the quality of AI-assisted development — the graph provides the map, the AI reads the territory. diff --git a/pdr.md b/pdr.md deleted file mode 100644 index 1c2536a..0000000 --- a/pdr.md +++ /dev/null @@ -1,361 +0,0 @@ -# AI Code Graph for .NET -## Product Design Requirements (PDR) - ---- - -## 1.
