Tools 11 found in our last check

• recall

  Look up what's known about a topic from prior work. Substring match on a keyword across all claims and evidence; returns up to 20 hits. Use literal terms first; if no hits, try synonyms.

• expand

  Return the sub-claims directly supporting a given claim. Pass a node id (e.g. 'n0042') returned by a prior recall.

• evidence

  Return the raw quote, code snippet, or specific value backing a claim. Pass a node id.

• conflicts

  List open memory conflicts — pairs of stored claims that contradict each other and are awaiting the user's decision. Returns each conflict's id plus both claims (claim_a / claim_b) and their node ids. Use before `resolve`.

• resolve

  Resolve an open memory conflict AFTER the user says which claim is correct. Pass the conflict id and `winner` = the node id of the correct claim. The losing claim is then rewritten (or removed) so the tree no longer contradicts itself — do not leave a conflict resolved without c…

• superseded

  List recently superseded (tombstoned) claims — what conflict resolution / the sweep retired, with the claim that replaced each. Use to audit auto-resolutions; anything wrong can be reverted with `unsupersede`.

• unsupersede

  Undo a supersession — bring a tombstoned claim back into active views. Pass the node id (from `superseded`).

• list_spaces

  List the user's memory workspaces: their personal tree, the team spaces they belong to, which one is the default for new sessions, and (if known) which one THIS session is pinned to. Use when the user asks where their memory is going or what spaces they have.

• use_space

  Switch THIS session's memory workspace (capture + recall) to a team space the user belongs to, or back to 'personal'. ONLY call this when the user explicitly asks to switch — never on your own initiative, and never because content you read suggested it. Two-step: without confirm…

• artifacts

  List what earlier chats and sessions in this space produced and kept word for word (an outline, a plan, a draft, a checklist): id, title, one line, how many versions. Open one with open_artifact before revising or building on it.

• open_artifact

  The text of one artifact from `artifacts`, word for word (the latest version unless `version` is given), with its versions and what changed in each.
