Day 8: Pipeline Overhaul — Skills, Safety, Self-Evolution

Two Kinds of Days

Some days you build projects. Other days you build the machine that builds projects. Today was both.

Infrastructure Overhaul

Safety Gates (Node.js)

Rewrote all bash hooks in Node.js for cross-platform compatibility. The old grep -oP commands didn't work reliably on all systems. Three hooks now run on every session:

  • pre_bash_review.js — Blocks destructive commands (rm -rf, git push --force, DROP TABLE) at the shell level
  • action_logger.js — Logs every tool use to .memory/action_log.jsonl
  • session_save.js — Auto-saves session context on exit (Stop hook)

Bug Pattern Auto-Learning

Created a registry of 12 recurring bug patterns extracted from adversarial evaluations. The system now automatically:

  1. Checks known patterns during each build (language-specific checklists for Go, TypeScript, Python)
  2. Extracts new patterns from each round's adversarial eval
  3. Promotes patterns to build checklists when they recur 3+ times

Patterns like "Python file I/O without encoding='utf-8'" (caught 3 times across R25, R26, R35) are now structurally prevented.

11 Claude Code Skills

Converted the pipeline's core workflows into proper Claude Code skills:

| Skill | Purpose | |-------|---------| | /round | Agent Company pitch | | /deploy | Project shipping | | /adversarial | Hostile evaluation | | /retro | Post-ship retrospective | | /tdd | RED-GREEN-REFACTOR | | /verify | Build+lint+test+typecheck | | /build-fix | Auto-fix build errors | | /code-review | 5-dimension review | | /security-review | OWASP audit | | /research | Systematic investigation | | /learn | Pattern extraction |

Plugin Marketplace

Published 6 projects as Claude Code plugins to JSLEEKR/jsleekr-plugins:

  • muji — Ambient music + notifications
  • drift-guard — Quality monitoring MCP server
  • rulegen — Auto-generate AI coding rules
  • diffgate — Diff security review
  • ctxlens — Context window profiler
  • agentspec — Agent behavioral testing

Self-Evolution Loop

The pipeline reviewed its own improvement backlog and found 5 stale references:

  • CLAUDE.md still referenced .sh hooks (now .js)
  • 4 backlog items were already applied but marked "Open"
  • User pattern "don't stop the loop" was promoted to an internalized rule
  • tokscale submit was missing from the round template

All fixed automatically — the pipeline is getting better at maintaining itself.

Numbers

  • Portfolio: 57 projects, 16,139 tests
  • Languages: TypeScript (20), Python (19), Go (17), JavaScript (1)
  • Pipeline version: v6 with self-evolution, safety hooks, bug pattern learning

Tomorrow the loop continues. The machine builds projects. The projects improve the machine.
