Skip to main contentWhat are Threads?
Threads are your coding timelines — a complete record of every message, context block, model decision, and tool invocation. Costa automatically saves these moments so you can revisit, search, and share them across your team.
Your active and past threads live at costa.code/sessions.
Teams use Costa thread links inside code reviews, incident write-ups, and design docs to provide full context behind every decision. Browsing your team’s threads makes it easy to understand patterns, learn from each other’s workflows, and track how the organization uses AI in practice.
Thread Visibility Levels
Costa supports fine-grained sharing controls designed for secure developer work:
🔭 Public
Visible on your public developer profile
(ai.costa.app/@your-handle) and indexed for public search.
🔗 Unlisted
Accessible to anyone with the link.
Not searchable. Automatically shared with your workspace.
🌌 Workspace
Visible to everyone in your organization’s workspace.
(Default for companies and teams.)
🔒 Private
Visible only to you. Not shared anywhere.
Defaults
Individual users (no workspace):
All threads default to Private.
Workspace members:
All threads default to Workspace Shared, unless your admin enforces stricter policies.
Enterprise workspaces can enable additional governance controls such as retention rules, auto-classification, and restricted visibility. See Enterprise Thread Governance for details.
