What is developer-tools CLAUDE.md?

Repository instructions for a collection of developer skills adapted for Israeli-related tools and workflows. They describe the required folder and file structure, naming rules, and validation checks for each skill.

Use them when creating, editing, or reviewing skills in the developer-tools repository. They cover SKILL.md files, YAML metadata, kebab-case folder names, and repository validation.

They prevent skills from being rejected by automated checks because files, folders, or metadata are formatted incorrectly. They also explain how the repository is organized so contributors can follow its conventions.

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.

Model	Per session	Once invoked
Fable 5	$0.00451	$0.00451
Opus 5	$0.00226	$0.00226
Sonnet 5	$0.00090	$0.00090
Haiku 4.5	$0.00045	$0.00045

Security

Grade A, and why

developer-tools 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 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.

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.

Origin

This is a copy

94% identical to localization CLAUDE.md — 37 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Project Overview

This is a Skills IL category repository containing AI agent development utilities with Israeli adaptations. Each subdirectory is a self-contained skill following the open Agent Skills standard.

Skill Format (CRITICAL)

Every skill is a folder containing a SKILL.md file. The folder name MUST be kebab-case.

Validation Rules

These rules are enforced by CI on every PR:

File must be exactly SKILL.md (case-sensitive)
YAML frontmatter must have --- delimiters on both sides
name field: kebab-case only, must match folder name
description field: present, under 1024 chars, no XML angle brackets, must include WHAT + WHEN
SKILL.md body must be under 5,000 words
No README.md inside skill folders
No skill names containing "claude" or "anthropic"
No hardcoded secrets

See CONTRIBUTING.md for the full guide.

Commands

./scripts/validate-skill.sh <skill-folder>/SKILL.md

Conventions

All skill folders use kebab-case naming
Bilingual content should use { he: "...", en: "..." } when applicable
Israeli-specific context should reference official sources
Org-level files are inherited from skills-il/.github

Changes

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.
