Our verdict: worth keeping an eye on

Measured 2026-09-27 (Sonnet subagents, r/ClaudeAI top-of-week task): the 90% repeat-visit claim did not reproduce. Warm runs cost 11% MORE than cold (102.8k vs 92.4k tokens) because the agent following the bundled SKILL.md never ran candidate add or checkpoint in 3 of 3 runs, so no site memory existed to reuse (reddit.com had no vendor seed). It did reach Reddit data WebFetch/Exa/curl cannot (cold 92k tokens with a correct answer vs baseline 149k tokens and no answer). Our nightly research reads all sources by API/RSS (0 browser tokens), so it has nothing to save there. Security: CAUTION not malicious. Never for client logins. Borrow the per-site SITE.md memory pattern, with the write step enforced.
