From 16c93d35071ca8b9c569e2e90aad0d7a1b4bcdfc Mon Sep 17 00:00:00 2001 From: prosdev Date: Sun, 14 Dec 2025 15:16:03 -0800 Subject: [PATCH 1/4] refactor(mcp)!: replace dev_explore with dev_inspect tool - Renamed dev_explore to dev_inspect for clarity - Changed actions to specific verbs: compare, validate - Removed redundant pattern and relationships actions - Updated all documentation and tests - Added comprehensive migration guide BREAKING CHANGE: dev_explore tool has been replaced with dev_inspect. Use action 'compare' instead of 'similar', and 'validate' for pattern checks. The 'pattern' action is replaced by dev_search, and 'relationships' by dev_refs. --- .changeset/dev-explore-to-dev-inspect.md | 44 ++ AGENTS.md | 2 +- CHANGELOG.md | 2 +- CLAUDE.md | 2 +- PLAN.md | 8 +- README.md | 10 +- TROUBLESHOOTING.md | 10 +- examples/README.md | 26 +- packages/cli/src/commands/mcp.ts | 4 +- packages/core/src/observability/README.md | 4 +- .../__tests__/observability.test.ts | 10 +- packages/dev-agent/README.md | 4 +- packages/mcp-server/CLAUDE_CODE_SETUP.md | 19 +- packages/mcp-server/CURSOR_SETUP.md | 19 +- packages/mcp-server/README.md | 14 +- packages/mcp-server/bin/dev-agent-mcp.ts | 6 +- .../__tests__/explore-adapter.test.ts | 425 ----------- .../__tests__/inspect-adapter.test.ts | 478 +++++++++++++ .../src/adapters/built-in/explore-adapter.ts | 668 ------------------ .../mcp-server/src/adapters/built-in/index.ts | 24 +- .../src/adapters/built-in/inspect-adapter.ts | 390 ++++++++++ packages/mcp-server/src/schemas/index.ts | 31 +- packages/mcp-server/src/server/prompts.ts | 14 +- website/content/docs/configuration.mdx | 2 +- website/content/docs/quickstart.mdx | 2 +- website/content/docs/tools/_meta.js | 2 +- website/content/docs/tools/dev-explore.mdx | 100 --- website/content/docs/tools/dev-inspect.mdx | 114 +++ website/content/docs/tools/dev-refs.mdx | 2 +- website/content/docs/tools/index.mdx | 4 +- website/content/index.mdx | 2 +- website/content/updates/index.mdx | 4 +- 32 files changed, 1156 insertions(+), 1290 deletions(-) create mode 100644 .changeset/dev-explore-to-dev-inspect.md delete mode 100644 packages/mcp-server/src/adapters/__tests__/explore-adapter.test.ts create mode 100644 packages/mcp-server/src/adapters/__tests__/inspect-adapter.test.ts delete mode 100644 packages/mcp-server/src/adapters/built-in/explore-adapter.ts create mode 100644 packages/mcp-server/src/adapters/built-in/inspect-adapter.ts delete mode 100644 website/content/docs/tools/dev-explore.mdx create mode 100644 website/content/docs/tools/dev-inspect.mdx diff --git a/.changeset/dev-explore-to-dev-inspect.md b/.changeset/dev-explore-to-dev-inspect.md new file mode 100644 index 0000000..f3562be --- /dev/null +++ b/.changeset/dev-explore-to-dev-inspect.md @@ -0,0 +1,44 @@ +--- +"@lytics/dev-agent-mcp": patch +"@lytics/dev-agent": patch +"@lytics/dev-agent-cli": patch +--- + +Refactor: Rename dev_explore → dev_inspect with focused actions + +**BREAKING CHANGES:** + +- `dev_explore` renamed to `dev_inspect` +- Actions changed from `['pattern', 'similar', 'relationships']` to `['compare', 'validate']` +- Removed `action: "pattern"` → Use `dev_search` instead +- Removed `action: "relationships"` → Use `dev_refs` instead +- Renamed `action: "similar"` → `action: "compare"` + +**What's New:** + +- `dev_inspect` with `action: "compare"` finds similar code implementations +- `dev_inspect` with `action: "validate"` checks pattern consistency (placeholder for future) +- Clearer tool boundaries: search vs. inspect vs. refs +- File-focused analysis (always takes file path, not search query) + +**Migration Guide:** + +```typescript +// Before +dev_explore { action: "similar", query: "src/auth.ts" } +dev_explore { action: "pattern", query: "error handling" } +dev_explore { action: "relationships", query: "src/auth.ts" } + +// After +dev_inspect { action: "compare", query: "src/auth.ts" } +dev_search { query: "error handling" } +dev_refs { name: "authenticateUser" } +``` + +**Why:** + +- Eliminate tool duplication (`pattern` duplicated `dev_search`) +- Clear single responsibility (file analysis only) +- Better naming (`inspect` = deep file examination) +- Reserve `dev_explore` for future external context (standards, examples, docs) + diff --git a/AGENTS.md b/AGENTS.md index b7ae3d5..1155693 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -191,7 +191,7 @@ MCP server with built-in adapters for AI tools. -

Content-Transfer-Encoding: 8bit - Created PatternAnalysisService in @lytics/dev-agent-core - 5 core patterns: file size, testing, imports, error handling, types - Pattern comparison against similar files - 31/31 tests passing with comprehensive fixtures - Integrated PatternAnalysisService into InspectAdapter - Removed action parameter (single-purpose tool) - Added patternsAnalyzed field to output schema - Real pattern analysis in compact & verbose formats - 18/18 tests passing with dedicated fixtures - Clean architecture - Barrel exports for types - Fixtures excluded from compilation, linting, and type-checking - Separate fixture sets for unit (core) and integration (adapter) tests Test coverage: - PatternAnalysisService: 31 tests ✅ - InspectAdapter: 18 tests ✅ - Build: successful
