  • Automating the PARA Weekly Review with Claude Projects and Notion MCP AIProductivity

    The PARA weekly review is supposed to be a habit. In practice, it competes with everything else on a Monday morning and (for me) loses. Tiago Forte describes the process clearly and if you do it you feel better, but manually working through six databases and writing a summary takes sustained focus that is easy to defer. You could open a Claude conversation instead, but you’d spend the first ten minutes copy-pasting database schemas, re-explaining your workflow, and reconstructing context that evaporates the moment you close the tab. By the time Claude is useful, you’ve burned more energy than the review itself would have taken.

  • Your Best Ideas Come at the Worst Time: Building a Low-Friction Capture System for Developers ProductivityAI

    I was mid-feature in a Claude Code session when a /simplify pass triggered a bigger idea: retrofit simplification systematically across the whole codebase. Claude gave me a 300-word response sketching how that might work. Useful idea, concrete starting point.

    But the idea had nothing to do with what I needed to finish NOW. I told myself I would come back to it … I did not come back to it.

  • Catching Spec-Kit Task Phantom Completions with /speckit.verify-tasks AI

    Update (v1.1.0): The install command now requires the --from flag pointing at the release archive. See the Install section below for the updated command.

    AI agents sometimes mark tasks [X] without doing the work. These phantom completions are rare (~0.36% in my data), but each one is a false claim you’ll either accept or spend precious mental energy figuring out the truth. verify-tasks is a spec-kit community extension that runs a multilayer verification cascade against every [X] completion in your tasks.md and passes a verdict on whether the work was actually done.
