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.

Investigate

With no precedent, a cluster-setting preflight hits a real database boundary and the Skill recovers safely.

Retain

Evidence, recovery, provenance, and a canonical execution embedding are committed to CockroachDB.

Recall

A related investigation finds that experience and avoids the known dead end.

Real by construction

Not chat history.
Execution evidence.

01

Database-enforced boundaries

A restricted SQL identity—not a prompt—blocks privileged cluster-setting inspection.

02

Two ways to remember

Filtered vector recall before a run. Deterministic failure fingerprints during it.

03

Auditable influence

Every derived memory links back to its source run and forward to every run it influenced.
