Pull requests are historical outcome anchors, not finished prompts. Review each task description and define its evaluator before running the experiment.

Control A

No repository context

Run each task from its historical base commit with repository instruction files hidden.

Treatment B

Current context

Repeat from the same base commit with the detected instruction surface restored.

Static review

Instruction health checks

No obvious static issues found

The automated checks found no oversized files, thin instruction files, duplicated long rules, or broken relative Markdown references. Runtime testing is still required.

Outcome scorecard

What the runner must measure

Verified completion

Repository tests and task-specific assertions pass.

Regression count

Previously passing behavior remains intact.

Cost

Input/output tokens and provider spend per successful task.

Time

Wall-clock duration and number of agent steps.

Exploration

Files read or modified outside the expected change area.

Instruction adherence

Concrete applicable rules followed or violated.

Put this brief to work

Replay it with the free local runner, review the evidence, and keep noisy results inconclusive.

This is an experiment brief, not a benchmark result.

Sharper Than AI has prepared reproducible inputs from public repository evidence. It has not run a coding agent or claimed that the current instructions help.
