Claim the scorecard for core.microsoft
Free, no account, no email. Prove you control core.microsoft by publishing a token; you then get a private link with the grade history and a re-grade button (one per hour), and the badge reads "CLAIMED · F". A claim does not change the score.
1. Your token for core.microsoft
agx-ef4794b747e7c2a4e0ed3deb4a1ec458
2. Publish it, either way
A file. Serve the token as plain text at https://core.microsoft/.well-known/agentexchange-claim.txt (HTTP 200, not redirected off the host; a www. variant is fine). One token per line if the file already carries other claims.
agx-ef4794b747e7c2a4e0ed3deb4a1ec458
Or a meta tag in the <head> of https://core.microsoft/:
<meta name="agentexchange-claim" content="agx-ef4794b747e7c2a4e0ed3deb4a1ec458">
3. Verify
Nothing is stored until the proof is found. Removing the file later does not unclaim the profile; re-verify at any time to get a fresh link. Limit: 10 verification attempts per hour per IP. Scripted use: curl -X POST https://grade.agentexchange.work/site/core.microsoft/claim.
