ultrawork-lessons

ultrawork-lessons is a command for Claude Code from mnthe/hardworker-marketplace. It costs 16 tokens per session (472 once invoked), scanned A, original, MIT.

A command for displaying lessons recorded from previous ultrawork sessions in a project. It reads dated lesson files and summarizes recurring failures, fixes, and recommendations.

In plain words
What is it for?
Use it to review all recorded lessons or request only the latest few sessions, including their summaries, recurring problem patterns, and suggested actions.
Why use it?
Useful knowledge from earlier sessions can be difficult to find when it is spread across many documents. This command gathers it into a recent or complete dashboard.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ultrawork-lessons scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Ultrawork Lessons Dashboard

Overview

Display lessons learned from previous ultrawork sessions in this project. Lessons are extracted by the documenter after each session and stored in docs/lessons/.

Usage

/ultrawork-lessons          # Show all lessons for current project
/ultrawork-lessons --last 5 # Show 5 most recent

Workflow

  1. Find lessons files:

    Glob("docs/lessons/*.md")
    
  2. Sort by filename (date prefix ensures chronological order), newest first

  3. If --last N specified, take only the N most recent files

  4. For each file, read and display:

    • Session Summary (date, tasks, Ralph loops)
    • Key Failure-Fix Patterns (pattern name + takeaway)
    • Recommendations (actionable items)
  5. At the end, show aggregated summary:

    • Total sessions with lessons
    • Most common failure patterns across sessions
    • Top recurring recommendations

Output Format

## Lessons Dashboard

### Recent Sessions

#### 2026-03-18: Auth middleware refactor
- Tasks: 8 (6 first-pass, 2 fix)
- Ralph Loops: 1
- Key lesson: lint를 worker 단계에서 미리 실행할 것

#### 2026-03-15: API endpoint migration
- Tasks: 5 (all first-pass)
- Ralph Loops: 0
- (No failures — clean session)

### Aggregated Insights
- Total sessions: 5
- Average Ralph loops: 0.8
- Most common failure: lint violations (3 sessions)
- Top recommendation: "Run lint before verification"

Edge Cases

  • No docs/lessons/ directory -> Display: "No lessons found. Lessons are created after ultrawork sessions complete."
  • Empty directory -> Same message
  • Only clean sessions (no failures) -> Show sessions but note "clean completion"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
