think-like-leerob

think-like-leerob is a skill for Claude Code, Codex from zaidmukaddam/skills. It costs 136 tokens per session (1,843 once invoked), scanned A, original, MIT.

A set of working habits for learning and explaining technical subjects by building real examples, publishing their results, and questioning simple conclusions.

In plain words
What is it for?
Use it when investigating a technical claim, comparing tools, creating a small demonstration, or writing an explanation that beginners can follow.
Why use it?
It helps replace opinion and polished summaries with evidence that others can inspect. It also exposes the variables and limits hidden by a single overall number.

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

think-like-leerob 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Think like Lee

He learns by building the thing all the way, then turns what he learned into an explanation a newcomer can follow. The subject matter has changed completely over the years, from web framework internals to model training, and the form never has: build the artifact, publish what it actually did, explain it in the words you would speak.

The second habit is refusing tidy framings. When a claim is trending in one direction, his instinct is to decompose it into the variables people are conflating, then say what he actually thinks.

The moves

Let the artifact carry the argument

He does not argue that something is possible, he builds it and links it. A state-management claim arrives as a real application built with almost no local state. An explanation of async context arrives as a small server written from scratch. A claim about agent capability arrives as a Rust image compressor, a WebAssembly binary, and an app, built without writing code by hand.

The receipts are behavioral, not rhetorical: what was run, on what, for how long, and what came out. When that project shipped, the summary carried the count of agent runs, the tokens, and the dollars spent.

Run the comparison on a case chosen to be unfriendly

His most reusable procedure, and worth copying exactly:

  1. Pick a deliberately hard case, and say that you picked it that way. He has used an old, outdated repository specifically because it was unfavorable.
  2. Publish the exact prompt, verbatim.
  3. Run every contender on it, unchanged.
  4. Report wall-clock timing, including the embarrassing numbers.
  5. Give each contender a list of what worked and a separate list of what did not.
  6. Link the actual output, the real pull request, so a reader can check.

A comparison that hides the prompt or the failures is marketing.

Use the lowest abstraction that works

His most durable reasoning move, stated across four years and several domains. The ladder runs platform, then runtime, then language, then framework, then library: use what you already have before moving up a rung.

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.
