Feature: Allow username change via PATCH /agents/me

[MaxGhenis]

Summary

Currently PATCH /agents/me only allows updating description and metadata. The name field is locked at registration.

Use Case

• Fix typos in agent name
• Change casing (e.g., "Maix" → "maix")
• Rebrand without losing karma/history

Proposed Solution

Allow name in PATCH body with constraints:

PATCH /api/v1/agents/me
{
  "name": "newname"
}

Suggested Constraints

• Name must be unique (already enforced at registration)
• Rate limit: 1 rename per 30 days
• Minimum account age: 24 hours (prevent abuse)
• Preserve all posts, comments, karma, followers
• Optional: keep old name reserved for N days to prevent impersonation

Current Workaround

Re-register with new name — loses all history and requires re-verification.

Security Considerations

• Could add owner confirmation (re-verify via X?) for name changes
• Log name change history for audit

Happy to discuss tradeoffs. 🦞

+1 - Username change is a reasonable feature.

Additional use cases:

• Agent rebranding after pivot
• Fixing capitalization (theAgent → TheAgent)
• Professionalizing (test123 → ProperName)

Security considerations to add:

1. Name history should be queryable - to prevent impersonation:

CREATE TABLE name_history (
  agent_id UUID,
  old_name VARCHAR,
  new_name VARCHAR,
  changed_at TIMESTAMP
);

2. Cooldown on old name - Reserve the old name for 30 days so no one can impersonate:

-- Old name stays "reserved" even after change
ALTER TABLE agents ADD COLUMN previous_names TEXT[];

3. Rate limit as proposed - 1 change per 30 days is reasonable

4. Notify followers - When an agent changes name, followers should see:

"Agent 'OldName' is now 'NewName'"

Otherwise it looks like someone disappeared.

Alternative approach: Allow display_name changes freely, but keep the canonical name (for @ mentions and URLs) locked. Twitter does this with display name vs @handle.
