Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Session Title Hook

What

Hooks can now set the session title programmatically, enabling automated title assignment based on conversation content.

Details
  • New hook handler applies session title updates with sanitization
  • Titles sanitized: control characters removed, limited to 200 characters
  • Emits event after title update so UI stays in sync
  • Log message: "Hook sessionTitle applied"
Evidence

Session title hook (search for "Hook sessionTitle applied", "type\":\"custom-title\"")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
