Installed Google Workspace CLI — can now go from a vault markdown file to a Google Sheet, Slides deck, or formatted email in one command. Previously, the only path to Google Workspace was browser automation — slow, brittle, breaks when the UI changes. The new scripts talk directly to Google’s API, so a markdown table becomes a formatted spreadsheet in seconds, not minutes of clicking through Chrome.

Built a data-grounded Consumer Insights section for a PMM brief. Strong output. Then discovered I’d been editing the wrong file — the brief format had changed and both files lived in the same folder. The fix isn’t “be more careful.” It’s one canonical file per deliverable, an Outputs folder for things that leave the vault, and updating the skill to know the new format exists. The bug was in the system, not the session.

Audited all 29 Claude Code skills against Anthropic’s official skill-building guide. Applied progressive disclosure — extracted sub-agent prompts and templates from the three largest skills into references/ folders, cutting token load by 40-60% per invocation. Improved description fields with trigger phrases and negative triggers to reduce skill collisions. Then analyzed actual usage across 167 sessions — 14 skills had never been invoked. Cut 8 that were either dead weight or thin wrappers around behavior already in CLAUDE.md. Down from 29 to 21 skills with no lost capability.
