39 tools we reviewed and kept
We look at new AI, design and video tools every week and keep only the ones worth recommending — with one line on what each does and why.

AI coding 6
Context7 context7.comFeeds your coding agent current library docs instead of stale training data.
How we used itAlways on when we ask library questions — fewer round-trips fixing code written against old APIs.

Agent Skills (Addy Osmani) github.com/addyosmani/agent-skillsWalks an agent through plan, build, test, review and ship.

Design & UI 8
hallmark github.com/Nutlope/hallmarkSkill that finds 'AI-looking' design patterns on a page and lists fixes. We redesigned our own sites with it.
How we used itWe redesigned several of our public sites with it (hub, fund flows, hidden signals, Polymarket) — away from the default dark-navy AI look to pages where the key number reads first.

Tips 7
Same agent mistake three times? Fix the environment: rules in CLAUDE.md, procedures as skills, hard rules as hooks, repeat bugs as tests.
Give the agent success criteria, not a to-do list: write the test or the 'done when' lines first.
Let code compute the numbers; the AI only interprets, with guesses tagged [estimate].
Swap vague words for criteria: 'improve' → 'clarity, flow, CTA'; 'summarize' → '3 lines'. Name the reader.
Before stepping away from a long Claude Code session, /compact or /clear — resuming after the cache expires re-reads everything.
Don't paste 'give this URL to your agent to install'. Read the files and install from a pinned commit.
In AI video prompts, use camera terms — tracking shot, tilt up, snap zoom, rack focus, whip pan.
