What problem does it solve? Manually reviewing which notes were promoted from your Inkdrop inbox each month and compiling a retrospective summary is tedious and error-prone. This Skill automates the collection, tagging, and drafting of a monthly summary note directly in Inkdrop. ## Core Features & Use Cases - Automated note aggregation: Searches configured notebooks (tech/web-engineering, tech/AI, tech/infra, and more) via the Inkdrop MCP server and filters results locally by createdAt/updatedAt since Inkdrop search has no date modifier. - Template-based summary drafting: Generates a structured monthly summary with learnings, themes of interest, a promoted-notes table, and NotebookLM promotion candidates (tags with 3+ notes). - Multi-CLI MCP guidance: Provides invocation strategies for Claude Code, Codex, and Antigravity, including stateless JSON-RPC invocation through 1Password (op run) with parallelized calls to hide startup cost. - Use Case: At the start of June, ask the agent to build the May summary; it queries all target notebooks in parallel, filters May notes, and creates a "2026-05 月次サマリー" note in the monthly notebook. ## Quick Start Ask the agent to create the monthly summary for last month from my Inkdrop promoted notes and save it to the monthly notebook.
