# Skill Impact Tracker

> Inspired by WikiSkill (arXiv:2608.27454) — tracks skill modifications, their validation
> outcomes, and acceptance decisions. Prevents repeating failed modifications and provides
> an audit trail of skill evolution.

## How to Use

When a skill is patched, created, or deleted, append an entry to the table below.
The entry records WHAT changed, WHY, and WHETHER it helped (if validated).

### Entry Format

```
| Date | Skill | Change Type | Description | Validation | Outcome | Ref |
```

- **Change Type**: `created` | `patched` | `deleted` | `adopted`
- **Validation**: How was success measured? (`manual` | `tested` | `benchmark` | `n/a`)
- **Outcome**: `accepted` | `rejected` | `rolled-back` | `pending`
- **Ref**: Session ID or solution doc path

## Audit Trail

| Date | Skill | Change Type | Description | Validation | Outcome | Ref |
|------|-------|-------------|-------------|------------|---------|-----|
| 2026-08-30 | compound-learning | patched | Added WikiMaintainer phase + patterns/ guidance from WikiSkill paper analysis | tested | accepted | this session |
| 2026-08-30 | (retrospective) | created | 4 solution docs + 2 new patterns (PAT-008, PAT-009) from 30-day retrospective | tested | accepted | this session |
| 2026-08-13 | hindsight | patched | Expanded meta-memory automation table (decay scoring, drift detection, skill health) | tested | accepted | session 2026-08-13 |
| 2026-08-13 | (3 cron jobs) | created | Decay scoring, drift detection, skill health check — no_agent cron jobs | tested | accepted | session 2026-08-13 |

## Notes

- **Rejected proposals persist here** — they are NOT deleted. Future skill updates can
  consult this log to avoid repeating failed approaches (the WikiSkill paper showed this
  is critical for effective evolution).
- **Neutral changes** (no improvement, no regression) are recorded as `accepted` with
  `validation: manual` — they may enable future improvements.
- **Rollbacks** are explicitly tracked — if a skill patch caused regressions and was
  reverted, the entry stays with `outcome: rolled-back`.
