Current project.

Building agents that spend intelligence deliberately.

Local agent platform TARGET / 24 GB UNIFIED MEMORY
01 Code-change intelligence

Blackbox

Turns a diff into a bounded evidence neighborhood, combining static dependencies, runtime traces, and replay results so the agent can see the focused blast radius instead of the repository.

  • STATIC GRAPH
  • RUNTIME EVIDENCE
  • BLAST RADIUS
02 Adaptive agent runtime

Local harness

Runs a Qwen3 14B 4-bit SWE agent inside a 24 GB memory environment, measuring how harness policy changes capability per unit of inference.

  • QWEN3 14B
  • 4-BIT
  • 24 GB
03 Behavioral observability

BCOV

Turns agent trajectories into behavioral coverage, surfacing unevaluated behavior, regressions, and whether feedback changes future runs.

  • TRAJECTORIES
  • EVAL COVERAGE
  • REGRESSIONS
  • OBSERVABILITY

Thesis Can better systems design extract more effective intelligence from a fixed model?
