better-thinking CLAUDE.md

better-thinking CLAUDE.md is an instructions file for Claude Code from skyf0xx/better-thinking. It costs 978 tokens per session, scanned A, original, MIT.

Repository instructions for developing and installing the better-thinking Claude Code plugin, a collection of reusable procedures for thinking through tasks. They explain where skills live, how the dispatcher finds them, and which files must stay in sync.

In plain words
What is it for?
Use them when adding, editing, reviewing, or installing skills in the better-thinking repository, and when working with its marketplace setup.
Why use it?
They prevent contributors from looking in the wrong directories or changing generated indexes instead of the actual skill files.

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

better-thinking CLAUDE.md 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 6d 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 — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

This repo is the source for the better-thinking Claude Code plugin: a library of composable Agent Skills encoding thinking procedures. See README.md for what it is and how it's structured, and CONTRIBUTING.md for the rules a skill must follow (template, atomic vs. composite, token budgets, no personas).

Working in this repo

  • Skills are NOT one-directory-per-skill. Most skills — every atomic and composite skill in the library — are flat files at skills/library/<name>.md. Only the two orchestrators have their own directory + SKILL.md: skills/better-thinking/SKILL.md (the dispatcher) and skills/better-thinking-recipes/SKILL.md (the recipe runner). When looking for a skill by name, check skills/library/<name>.md first — don't assume skills/<name>/SKILL.md or search for a directory that doesn't exist.
  • Whichever file a skill lives in (skills/library/<name>.md or skills/<name>/SKILL.md) is the source of truth for it. skills/INDEX.json is a generated-by-hand mirror of every skill's frontmatter that the /better-thinking dispatcher reads to route — it must stay in sync with the actual files, not the other way around.
  • catalog/*.md holds full prose specs by category. A spec living in catalog/ is not the same as a skill existing — only an actual file under skills/ (skills/library/<name>.md, or skills/<name>/SKILL.md for the two orchestrators) makes it real. Don't let a catalog entry imply a skill exists when it doesn't.
  • Library skills (skills/library/<name>.md) are not independently invocable — Claude Code's harness only exposes top-level plugin skills (better-thinking, better-thinking-recipes) as directly callable. A library skill is only reachable by being routed to: better-thinking's dispatcher picks it via INDEX.json/ROUTE_INDEX.json, or better-thinking-recipes invokes it as a named dependency of a recipe stage. There's no /interview-synthesis-style direct slash command for a library skill.
  • skills/ROUTE_INDEX.json is a generated TF-IDF lexical index (name/one_line/triggers/category/Examples, field-weighted, stemmed) built from skills/INDEX.json + each skill file's Examples section (skills/library/<name>.md, or skills/<name>/SKILL.md for the two orchestrators) by scripts/build_route_index.py. The dispatcher (skills/better-thinking/SKILL.md step 3) runs scripts/route.py "<task>" against it for a lexical shortlist before confirming against INDEX.json — a token-overlap aid, not a semantic/embeddings search, so it can still miss a good match phrased very differently from the skill's own vocabulary. Never hand-edit ROUTE_INDEX.json.
  • After adding, editing, removing, or renaming any skill (or its related/dependencies, one_line, triggers, or ## Examples section), run both:
    python3 scripts/build_route_index.py
    python3 scripts/check_consistency.py
    
    check_consistency.py checks frontmatter validity, INDEX.json↔filesystem↔frontmatter sync, dangling [[wiki-links]], and catalog specs with no corresponding built skill. Fix everything it reports before considering the change done — this is exactly the class of drift that accumulates silently otherwise (see git history around 2026-07-09 for the incident that motivated writing it: a fully-specified scientific-method composite that several other skills depended on but that was never actually built — since resolved, the skill is built and registered). build_route_index.py must be re-run any time the text it's built from changes, or the router's shortlist goes stale relative to the actual skills.
  • There is no other build/test step. A change to this repo is a change to markdown and JSON files (plus regenerating ROUTE_INDEX.json when its inputs change).

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.
