Exogram Truth Vault

by Exogram

Stores verified facts, checks a claim for conflicts against them, and evaluates whether a proposed action is allowed before it happens.

Summary
evaluate_action then commit_action is a two-step the tool descriptions actually enforce.

Governance tooling usually amounts to logging what already happened. Here the order is written into the API: evaluate whether the action is admissible, then commit it with its outcome — and commit_action's own description says it must follow an evaluation. That makes the audit ledger meaningful rather than decorative. check_claim is the other genuinely useful one: asking whether a new statement contradicts what is on record is the check an agent never performs on itself.

What it is

Exogram's endpoint, which listed seven tools to our probe as exogram 2.1.2. Two halves: a vault of verified facts, and a governance layer that judges proposed actions and records what was done.

What you get
  • search_vault — semantic search over verified facts, with a minimum confidence threshold
  • check_claim — whether a claim conflicts with what is already on record, and which facts bear on it
  • store_record — commit a fact; it is embedded, encrypted and PII-scrubbed on the way in
  • evaluate_action — whether a proposed action is admissible under the user's governance policy
  • commit_action — record the action and its outcome to a tamper-proof audit ledger, after evaluation
  • get_action_history and get_ledger_stats — the ledger, and the vault's size and quality
Requirements
