Curated Guidelines

harness-doctor

Claude Code / Codex skill that mines the last N days of Claude Code transcripts across every project on the machine into five fact tables — bash, errors, tokens, human corrections, fan-out — and returns a ranked list of fixes with the measured number behind each one.

Effect Skill

Kit Langton's opinionated agent skill for building production TypeScript apps with Effect v4 — workflows, services, layers, schemas, config, schedules, caches, streams, HTTP clients, and tests, with current APIs and production defaults.

context-doctor

Claude Code / Codex skill that audits the fixed context a coding agent auto-loads every session — tool/MCP definitions, connectors, plugins, skills, subagents, memory/rules files — and proposes ranked cuts to prune, gate, or route what's loaded but unused.

memory-view

Claude Code / Codex skill that reads a project's auto-memory vault and generates a self-contained HTML explorer to visualize what the agent has remembered — MEMORY.md plus topic files — without editing or managing it.

session-report

Claude Code / Codex skill that generates a self-contained HTML report debugging what is in a session's context window and how every token is spent — context budget, retained thinking, the dumb-zone cutoff, loaded CLAUDE.md and skills, and full history.

teach

Matt Pocock's skill that turns a coding agent into a personal tutor — it builds a stateful learning workspace and designs lessons within your zone of proximal development to teach you any skill or concept over multiple sessions.

quality-code

Rhys Sullivan's TypeScript coding skill — branded types, discriminated unions, end-to-end types, real tests over mocks, OpenTelemetry observability, and picking the right abstractions instead of premature ones.

improve-codebase-architecture

Matt Pocock's skill for deepening modules — restructuring prototype code into something long-lived with cleaner layer dependencies and easier navigation.
