From 92a501c4092196c87cc8b5b8121c349ce106b687 Mon Sep 17 00:00:00 2001 From: prosdev Date: Sat, 13 Dec 2025 13:43:11 -0800 Subject: [PATCH] feat(cli): add dev activity and dev owners commands with indexed author contributions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add 'dev activity' command showing most active files with commit counts and complexity - Add 'dev owners' command with developer specialization breakdown - Index author contributions during 'dev index' for 35x speedup (17.5s โ†’ 0.5s) - Add file_authors table to MetricsStore schema - Implement batched git operations (1 call vs N file calls) - Refactor metrics commands to top-level for better UX - Add compact table format with factual summaries - Add GitHub handle resolution for developer identification - Remove deprecated 'dev metrics' command Performance improvements: - Batched git log reduces overhead from O(N files) to O(1) - Indexed author data enables offline queries - No git access needed after initial indexing Breaking changes: - 'dev metrics activity' โ†’ 'dev activity' - 'dev metrics ownership' โ†’ 'dev owners' - 'dev metrics size' removed (redundant) --- .changeset/huge-release-v0-8-0.md | 79 +++++ packages/cli/src/cli.ts | 6 +- packages/cli/src/commands/activity.ts | 169 ++++++++++ packages/cli/src/commands/index.ts | 9 +- packages/cli/src/commands/metrics.ts | 260 --------------- packages/cli/src/commands/owners.ts | 304 ++++++++++++++++++ packages/cli/src/commands/update.ts | 5 + packages/core/src/events/types.ts | 5 + packages/core/src/indexer/index.ts | 16 +- .../src/indexer/utils/change-frequency.ts | 112 +++++++ packages/core/src/metrics/collector.ts | 22 +- packages/core/src/metrics/schema.ts | 25 ++ packages/core/src/metrics/store.ts | 91 ++++++ 13 files changed, 831 insertions(+), 272 deletions(-) create mode 100644 .changeset/huge-release-v0-8-0.md create mode 100644 packages/cli/src/commands/activity.ts delete mode 100644 packages/cli/src/commands/metrics.ts create mode 100644 packages/cli/src/commands/owners.ts diff --git a/.changeset/huge-release-v0-8-0.md b/.changeset/huge-release-v0-8-0.md new file mode 100644 index 0000000..fb6372a --- /dev/null +++ b/.changeset/huge-release-v0-8-0.md @@ -0,0 +1,79 @@ +--- +"@lytics/dev-agent": minor +"@lytics/dev-agent-cli": minor +"@lytics/dev-agent-core": minor +"@lytics/dev-agent-mcp": minor +"@lytics/dev-agent-subagents": minor +"@lytics/dev-agent-types": minor +--- + +## ๐ŸŽ‰ v0.8.0 -
