# Improvement Log

<Infobox>
| **System** | DMAIC Improvement Pipeline |
| **Review Cadence** | Weekly (Sunday 8 PM UTC) |
| **Promotion Threshold** | 2+ weeks with improving target metric |
| **Retirement Threshold** | 2+ weeks with no improvement |
| **Pattern Detection** | 3+ occurrences in one week |

## Overview

This page tracks the continuous improvement pipeline for the wiki agent cluster. The `wiki-retro` weekly task scans daily logs for recurring patterns, creates candidate rules, and promotes or retires them based on metric evidence.

Rules that prove effective after 2+ weeks are promoted to `agents/wiki-cluster.md` (Tier 1). Ineffective rules are retired here with a note on why.

## Active Rules

*Rules promoted from candidates. Each includes the date promoted and the metric it improved.*

- *No rules promoted yet — system is in baseline collection phase.*

## Candidate Rules

*Patterns detected 3+ times in a week. Under observation for 2 weeks before promotion or retirement.*

| Pulse health at 0.0% for 7+ consecutive days | 2026-04-01 through 2026-04-05 (all snapshots) | Investigate pulse record classification — records may be written with incorrect status or pulse agent may not be running. Fix pulse health data pipeline before baseline completes. | system_health_score | NEW — 2026-04-05 |
| Zero tweets sent in 7d with queue depth 4-5 | 2026-04-01 through 2026-04-05 (all snapshots) | Twitter posting pipeline is stalled. Diagnose post-next-tweet.sh or scheduled task execution. Restore 3x daily tweet cadence. | distribution_velocity | NEW — 2026-04-05 |
| Moltbook errors every 24h cycle (2-6 errors/day, increasing) | 2026-04-01 through 2026-04-05 (all snapshots) | Diagnose moltbook agent failure mode. Errors are the sole contributor to agent_error_rate_7d (now 4.2% and rising). Fix or disable moltbook until root cause resolved. | agent_error_rate_7d | NEW — 2026-04-05 |

## This Week — 2026-04-05 (W14)

### Retrospective Summary

**Baseline status:** Day 8/14 — SPC control limits not yet active. No promotions or retirements possible (no candidates older than 2 weeks).

### Metrics Movement

- **Improved (1):** content_quality_score 0.757 to 0.797 (+5.3%)
- **Degraded (3):** agent_error_rate_7d 3.4% to 4.2% (+24%), system_health_score 0.687 to 0.683 (-0.6%), pages_updated_7d 122 to 7 (-94%)
- **Stable (4):** stale_pages_30d (14), coverage_gaps (0), mend_success (100%), tweets_expired (0)
### Patterns Detected (3 new candidates)

1. $1
2. $1
3. $1
### Priority for Next Week

Fix the tweet posting pipeline — offline 10+ days, largest drag on distribution_velocity. Secondary: investigate pulse_health 0.0%.

## Retired Rules

*Candidates that were active 2+ weeks but did not improve their target metric.*

- *No retirements yet.*

## Monthly Review

*Monthly summary of the improvement pipeline effectiveness.*

- *First monthly review pending.*
