Test report

Verdict: Tested · Works
Score: 9.2/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 296879e

Ran the job-seeking mini-task twice: baseline Claude wrote a 'Congratulations on your round!' email asking for a 20-30 min call; the skill version led with the reader's landing-page problem, used a lowercase name, and closed with a one-line weightless ask -- a concrete, checkable difference, not just vibes.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What Cold Message Writer does

Drafts cold outreach messages for LinkedIn, email, or X DMs across fundraising, hiring, partnerships, press/podcasts, and job-seeking situations. Triggers on phrases like 'cold email', 'DM this investor', 'reach out to', or 'land a job at [company]', and enforces rules like reader-first openers, one weightless ask, laddered proof, and AI-tell removal.
