nobrainer-tech-skills: Instructions file for Claude Code

CLAUDE.md

nobrainer-tech-skills CLAUDE.md is an instructions file for Claude Code from nobrainer-tech/nobrainer-tech-skills. It costs 2,188 tokens per session, scanned A, a copy of nobrainer-tech-skills AGENTS.md, MIT.

A set of repository rules for NoBrainer Agent Skills, a collection of reusable instructions for coding agents. It defines where skills, client adapters, tests, documentation, and shared assets belong.

In plain words
What is it for?
Use it when adding or updating skills, changing adapter files, checking repository structure, documenting compatibility, or running the project’s validation and regression tests.
Why use it?
It prevents duplicated or client-specific versions of the same instructions and makes changes easier to validate across supported coding-agent systems.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions Codex.

This is nobrainer-tech/nobrainer-tech-skills's own configuration. It tells Claude Code how to work on nobrainer-tech-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nobrainer-tech-skills configures →

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

nobrainer-tech-skills CLAUDE.md scanned grade A with 1 finding 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Working in nobrainer-tech-skills

This is the canonical, client-neutral NoBrainer Agent Skills source; adapters share skills/. Do not fork skills per client or claim runtime support from manifests; see docs/COMPATIBILITY.md.

Respect the host hierarchy; explicit user instructions override skill guidelines. Use Ultra's instruction-conflict and exact-source pause explanation.

CLAUDE.md must remain a byte-identical copy of this file.

Repository map

  • skills/<name>/SKILL.md — the exact active skill portfolio.
  • adapters/bootstrap.md — small shared routing context, not a skill.
  • Client manifests, hooks and .github/ — thin adapters and CI only.
  • scripts/validate_skills.py — portable structure and suite validator.
  • tests/ — deterministic and behavioral regression gates.
  • docs/COMPATIBILITY.md and docs/TESTING.md — proof boundaries.
  • docs/SKILL_CURATION.md — admission, ownership and retirement decisions.

Portable skill contract

Every active skill lives at skills/<skill-name>/SKILL.md and starts on line 1:

---
name: skill-name
description: "Use when ..."
---

The name is lowercase kebab-case, no longer than 64 characters, and equals its directory. Shared frontmatter contains only name and description. Descriptions explain when to trigger and may include short nb-* aliases. Aliases are phrases, never duplicate directories.

Keep bodies operational and client-neutral. Use relative links. Put long detail in focused references/ files and deterministic helpers in scripts/. Never depend on a user's filesystem, account, private host or current model name. Canonical public templates and examples use English; task-shaped BRIEF artifacts expose explicit Description and Definition of Done (DoD) fields, and Acceptance criteria use sequential IDs such as AC01 and AC02; bug reports and comments use one composite ENV: block with Name (QA, DEV, TEST, PROD, PREPROD, BETA or UNKNOWN), URL and User, while bug reports keep Description, Steps to reproduce, Current behavior and Expected behavior as separate fields and omit speculative workaround/root-cause fields; surface proof is separate: API uses a copyable curl request (method, URL, headers and body) plus response, DB uses separate read-only Query/Result code blocks, and UI uses Evidence for a screenshot or MP4 plus an optional HAR when the page-load/request chain matters; missing required proof returns INPUT_REQUIRED. The active portfolio is exactly fifteen nobrainer-* skills. A permanent skill must own a recurring cross-project boundary that no current skill or maintained native capability owns. Do not add one because a topic is popular.

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.
