03 · What Crbro Memory can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can remove for good, keeping a copy in .quarantine/ first - entries of a neuron, a whole neuron (two-step with confirm_token), a session log, create, strengthen, set the strength of or delete (action=disconnect) a connection between neurons, read (no arguments) or update the active working context - topics, open items, discard or clear, and find credentials stored in the brain, session logs included - reports the kind, never the value.

The 15 tools it gives your agent

Extracted from the project's README - what crbro-memory lets an agent do.

crbro_boot: - Boot the brain at session start - loads hot topics, context, the last three sessions and the retired_tools map
crbro_inspect: - Read-only views by id or name: view=status, neuron, neurons, sessions, global_map. view=neuron is an index by default - every entry as id, kind, date and previe
crbro_learn: - Store a fact, decision, pattern, preference, error or debt - with the keywords a future question may use. supersedes retires the old version in the same call
crbro_recall: - Search every stored line, not just topic names - returns what matched, how confidently, and the topic's next best lines. Several phrasings at once are fused by
crbro_revise: - Retire facts (and decisions, patterns, errors, debts via entries) as superseded or retracted, reactivate them with status=active, and edit summary, domain, tags
crbro_forget: - Remove for good, keeping a copy in .quarantine/ first - entries of a neuron, a whole neuron (two-step with confirm_token), a session log; restore and merge_into
crbro_connect: - Create, strengthen, set the strength of or delete (action=disconnect) a connection between neurons
crbro_context: - Read (no arguments) or update the active working context - topics, open items, discard or clear
crbro_map: - Keep one living map of how a topic's system works - replaced whole, never patched
crbro_consolidate: - End-of-session consolidation - the only way to log a session; links the topics it wrote and syncs spaces
crbro_maintenance: - Brain maintenance - heat, pruning, integrity, repair, unarchive, index rebuild
crbro_audit: - Find credentials stored in the brain, session logs included - reports the kind, never the value

show all 15 tools

crbro_secret: - Put a credential in the OS keychain and keep only its name in the brain
crbro_space: - Create, join, sync or leave a team space - a private git repo for shared projects
crbro_share: - Put one project into a space, after showing exactly what would be sent; unshare stops following it
