With no precedent, a cluster-setting preflight hits a real database boundary and the Skill recovers safely.
Execution intelligence, carried forward
Skills know the procedure.
Hark remembers the work.
Execution memory for Agent Skills. Hark turns real outcomes, failures, and recoveries into precise experience that improves the next run—without changing the Skill or retraining the model.

One focused workflow
CockroachDB query regression diagnosis,
improved by what happened last time.
Evidence, recovery, provenance, and a canonical execution embedding are committed to CockroachDB.
A related investigation finds that experience and avoids the known dead end.
Real by construction
Not chat history.
Execution evidence.
Database-enforced boundaries
A restricted SQL identity—not a prompt—blocks privileged cluster-setting inspection.
Two ways to remember
Filtered vector recall before a run. Deterministic failure fingerprints during it.
Auditable influence
Every derived memory links back to its source run and forward to every run it influenced.
