Got your hands on Claude Fable 5?
The first thing you should do is to upgrade your main projects with it, so it drastically impoves everything you've been working on.
Run this Audit & Project Improvement Prompt on each repo that's important to you (simply copy-paste it):
Repo Audit & Improvement Plan:
Prompt made by Claude Fable 5
You are a world-class principal-level software engineer and technical auditor. Your job is to deeply analyze this repository, produce an honest audit, and deliver a prioritized, actionable improvement plan. Work in the four phases below, in order. Do not skip ahead.
Ground every claim in actual files: cite file paths and line numbers. If you can't verify something, say so explicitly rather than guessing.
Phase 1 / Discovery & Mapping (read before judging)
Explore the repository systematically before forming any opinions:
Map the directory structure and identify the project type, language(s), frameworks, and runtime targets.
Identify entry points, core modules, and the main data/control flow through the system.
Read the package manifest(s), lockfiles, build config, CI config, environment/config files, and any docs (README, CONTRIBUTING, ADRs).
Determine what the project is for: its purpose, intended users, and apparent maturity (prototype, internal tool, production service, library).
Note conventions already in use (naming, module boundaries, error handling patterns, test style) so recommendations fit the existing culture rather than fighting it.
Output for this phase: a concise "Repo Map" purpose, stack, architecture sketch, key directories with one-line descriptions, and anything that surprised you.
Phase 2 / Audit (evidence-based, severity-rated)
Audit each dimension below.
For every finding, record: (a) what you found, (b) where (file:line), (c) why it matters (concrete consequence, not vague principle), (d) severity:
Critical / High / Medium / Low.
• Architecture & design: module boundaries, coupling/cohesion, circular dependencies, leaky abstractions, god objects/files, layering violations, scalability bottlenecks.
• Code quality: duplication, dead code, complexity hotspots (longest/most-branched functions), inconsistent patterns, error handling gaps (swallowed exceptions, missing edge cases), type safety holes.
• Security: hardcoded secrets or credentials, injection risks, unsafe deserialization, missing input validation, auth/authz weaknesses, outdated dependencies with known CVEs, overly permissive configs.
• Testing: coverage gaps (especially around core business logic), test quality (do tests assert behavior or just execution?), missing test types (unit/integration/e2e), flaky patterns, untestable code.
• Performance: N+1 queries, unnecessary allocations or copies, blocking calls in async paths, missing caching/indexing, unbounded growth (memory, files, queues).
• Dependencies: outdated, unmaintained, duplicated, or unnecessarily heavy packages; license risks; lockfile hygiene.
• DevEx & operations: build/setup friction, CI/CD gaps, missing linting/formatting enforcement, logging/observability quality, error reporting, deployment story.
• Documentation: README accuracy, onboarding path, undocumented critical behavior, stale docs that contradict code.
Rules for this phase:
Prefer 15 high-confidence findings over 50 speculative ones.
Distinguish facts ("this function has no error handling: src/api/client.ts:142") from judgments ("this module's responsibilities feel unclear") and label which is which.
Also list what the repo does well: strengths matter for deciding what to preserve.
Output for this phase: an "Audit Report": findings grouped by dimension, sorted by severity, plus a Strengths section.
Don't forget to mention all the ugly parts that need utmost priority.
Phase 3 / Improvement Strategy
Synthesize the audit into a strategy:
Identify the 3–5 themes that explain most of the findings (e.g., "no enforced boundaries between layers," "error handling is ad hoc").
For each theme, propose a target state and the principle behind it.
State explicit trade-offs: what you're recommending NOT to fix and why (effort vs. payoff, risk, project maturity).
Define what "done" looks like — measurable signals (e.g., "CI fails on lint errors," "core module test coverage ≥ 80%," "zero Critical findings").
Phase 4 / Detailed Task Plan
Convert the strategy into an execution plan:
Break work into discrete tasks. Each task must include: Title and one-paragraph description
Files/areas affected
Acceptance criteria (how we verify it's done)
Effort estimate (S = <2h, M = half-day, L = 1–2 days, XL = needs breakdown)
Risk of the change itself (could it break things?)
Dependencies on other tasks
Order tasks into milestones:
Milestone 0
Safety net: anything needed before refactoring safely (tests around critical paths, CI gates, backups).
Milestone 1
Critical fixes: security and correctness issues.
Milestone 2
High-leverage improvements: changes that make all future work easier.
Milestone 3
Quality & polish: remaining medium/low items worth doing.
Flag quick wins (high impact, S effort) separately so they can be done immediately.
For the top 3 tasks, include a brief implementation sketch (approach, key steps, gotchas).
Final Deliverable Format
• Produce a single document with these sections:
• Executive Summary (≤10 sentences: overall health grade A–F with justification, top 3 risks, top 3 opportunities)
• Repo Map
• Audit Report
• Improvement Strategy
• Task Plan (milestones + task table + quick wins)
• Open Questions: anything you need from a human to decide (product intent, deprecation candidates, performance targets)
Constraints
Do NOT modify any code during this audit. Analysis only.
Do not pad the report. If a dimension is healthy, say so in one sentence and move on.
Calibrate to the project's maturity. Don't recommend enterprise-grade infrastructure for a weekend prototype unless the owner's goals demand it.
Analyze the project's needs and provide recommendations in the most effective ways.
If the repo is large, prioritize depth in the core 20% of code that does 80% of the work, and note which areas received lighter review.
THE GUY WHO WON ANTHROPIC'S HACKATHON JUST GAVE AWAY HIS ENTIRE CLAUDE CODE PLAYBOOK FOR FREE. 10 MONTHS OF WORK, ALL PUBLIC
Affaan Mustafa won the Anthropic x Forum Ventures hackathon by building a full startup in 8 hours with Claude Code. Then he open-sourced the exact setup that did it. It's called Everything Claude Code, and it turns Claude from one assistant into an entire engineering team
Repo: affaan-m/ecc
This isn't a prompt pack. It's a system he refined over 10+ months of daily use shipping real products
What's inside:
A huge library of skills, dozens of specialized subagents, and ready-made commands, all working together. Each piece does one job. One subagent reviews security against OWASP standards. One optimizes memory so Claude stops forgetting earlier decisions around hour three. One learns from your past sessions and projects so the setup gets smarter the more you use it. Others handle planning, test-driven development, and language-specific code review
Instead of one assistant writing code, you get an orchestrated team. A main session delegates to the right specialist when the task calls for it, the way a real dev team splits work
The best part: it's not locked to one tool. It runs in Claude Code, Cursor, Codex and OpenCode, across Windows, Mac and Linux. Free, MIT licensed
This is the difference between using Claude like a search box and running it like a team that ships. The guy spent 10 months figuring out what actually works so you don't have to

karpathy's CLAUDE.md hit #1 on github trending.
220,000 stars. most devs still haven't read it.
it's 65 lines.
it took AI coding accuracy from 65% to 94%.
the 4 rules inside:
→ think before coding
state your assumptions. ask when unsure. never guess.
→ simplicity first
write the minimum code that solves the problem.
no abstractions nobody asked for.
→ surgical changes
don't touch code unrelated to the request.
every changed line must trace back to what was asked.
→ goal-driven execution
turn vague instructions into verifiable success criteria
before writing a single line.
that's it.
65 lines. 4 rules. 94% accuracy.

SOMEONE BUILT THE MOST COMPREHENSIVE CLAUDE CODE SYSTEM ON THE INTERNET AND OPEN SOURCED THE ENTIRE THING.
55 agents. 208 skills. 72 slash commands.
Built and won at the Anthropic x Cerebral Valley hackathon.
10 months of daily real-world use before it was ever published publicly.
This is not a collection of prompts someone threw together over a weekend.
This is a production-grade agent harness that has been stress-tested across thousands of real sessions and refined until it works reliably at scale.
Here is what you actually get when you install it.
55 specialized agents each built for a specific function. Not one agent trying to do everything. 55 agents each doing one thing exceptionally well.
208 skills covering every repeating workflow a serious builder runs. Research. Code review. Documentation. Testing. Deployment. Content. Analysis. Each one built once and callable forever.
72 slash commands that compress complex multi-step workflows into a single word.
A security scanner called AgentShield that audits your entire Claude Code configuration for vulnerabilities, misconfigurations, and injection risks across 5 categories before you deploy anything.
Cross-harness support for Claude Code, Codex, Cursor, OpenCode, and Gemini so the investment you make in this system is not locked to one tool.
A dashboard GUI with dark and light theme so you can monitor your entire agent operation from one screen.
Memory persistence that carries context across sessions so you never start from zero.
1,282 tests. 98% coverage. 102 static analysis rules.
This is the infrastructure layer most builders are trying to assemble piece by piece from 15 different repos.
Someone already built the complete version. Won a hackathon with it. Then gave it away for free.
The builders who install this this weekend will have a Claude Code setup that took 10 months of daily iteration to build.
Installed in one afternoon.

Anthropic just dropped a 25-minute video showing everything new in Claude Code. Official channel, not a course, not an influencer
Subagents, agent teams, background tasks, parallel workflows. Most people are still using Claude Code as a single-prompt chat
Karpathy just said the people who don't use LLMs are already losing.
he spent 4 minutes explaining why smart people are still going to fall behind.
Not only the people who refuse AI, but also those who think signing up for Claude counts as using it.
here's what it looks like for most people right now:
> ask Claude to rewrite an email
> ask Claude to summarize something
> close the tab
that's not wrangling Claude. that's paying $20/month for spell check.
Karpathy's point isn't that LLMs are powerful.
everyone knows that.
his point is that knowing how to use them is the actual skill gap and most people are nowhere near closing it.
Claude can be your research analyst, your writing editor, your salary negotiation coach, your financial reviewer, your 30-day curriculum builder.
all of that is in your $20/month subscription. right now. today.
most people will see this tweet, agree, and go back to asking Claude to fix a sentence.
the article below covers 20 prompts across every area of your life.
not productivity hacks.
actual use cases that change how you work and how you think.
the model is not the bottleneck. knowing what to ask is.
Google Cloud AI engineer just showed how they go from idea to deployed app at Google in 30-minutes using Claude.

one person + Claude + Google Cloud = a full engineering org running on a laptop.
worth more than any $500 vibe-coding course.
40% of the code Claude writes for you is wasted. you're paying for the rewrite.
a 65-line markdown file fixes it. 120,000 developers have starred it.
the author tested it on "30 codebases over 6 weeks" and reported a mistake rate drop from 41% to either 11% or 3%
depending on whether you read the headline or the body.
the irony is that the article is right.
CLAUDE.md is the most under-leveraged file in your stack.
65 lines of behavioral rules outperform a 4,000-token preferences dump.
"be careful" is useless. testable imperatives are gold.
"be senior" doesn't work Claude already thinks it is.
the 4 rules that ship the most leverage:
/ state assumptions, never guess silently
/ minimum code, nothing speculative
/ surgical changes, don't refactor adjacent code
/ define success, loop until verified
compliance: ~80%. mistake rate: from ~40% to single digits.
no human caught the contradicting numbers in the title.
nobody had to.
We’ve agreed to a partnership with @SpaceX that will substantially increase our compute capacity.
This, along with our other recent compute deals, means that we’ve been able to increase our usage limits for Claude Code and the Claude API.
