| # Governed Skill Evolution from Persistent Agent Experience |
|
|
| This repository contains a prospective ablation and cross-model transfer study |
| inspired by WikiSkill. It evaluates three ways to retain experience while |
| evolving a procedural Skill for permission-safe repository planning: |
|
|
| - no persistent history; |
| - flat chronological history; |
| - a persistent Pattern Registry and forward-chained Skill Impact Ledger. |
|
|
| The completed study contains three replicate sequences, three evolution |
| iterations per condition, 18 frozen cases, two model versions, and 87 completed |
| model calls. Persistent Wiki did not outperform flat history on task quality in |
| this setting. It used fewer input tokens and produced a larger target-model |
| Skill gain, but had lower final task quality and more rollbacks. |
|
|
| | Condition | Task quality | Input tokens | Rule lines | Rollbacks | Target-model Skill gain | |
| | --- | ---: | ---: | ---: | ---: | ---: | |
| | No Wiki | 87.4158 | 127016.7 | 28.3 | 2.33 | 12.7970 | |
| | Flat history | 89.6189 | 145269.3 | 41.0 | 1.67 | 9.6585 | |
| | Persistent Wiki | 87.3322 | 134773.7 | 32.7 | 2.00 | 11.6270 | |
|
|
| The result is intentionally bounded: one synthetic deterministic grader, three |
| replicates, and two Codex model versions in one model family. It is not a |
| provider comparison, safety certification, or general claim about Agent |
| performance. |
