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 5.1 | $0.01330 | $0.01330 |
| Opus 5.5 | $0.00532 | $0.00532 |
| Sonnet 5.5 | $0.00266 | $0.00266 |
| Haiku 4.5 | $0.00133 | $0.00133 |
Grade A, and why
ai-prompts 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 14d 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 — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Repository Purpose
This is a documentation-only library of reusable prompts, guides, and agent definitions for optimizing Claude Code workflows. There is no application code, no build system, no tests. All content is Markdown files organized in numbered directories.
Architecture
The library follows a sequential learning path (01 through 14), where each directory is a self-contained topic:
- 01-global-optimization - One-time
~/.claude/setup (CLAUDE.md global instructions, agents, skills) - 02-project-activation - Per-project Serena MCP activation and memory creation
- 03-custom-skills - Skill authoring guide + template (YAML frontmatter + Markdown body, placed in
~/.claude/skills/<name>/SKILL.md) - 04-research-integration - Keeping docs current with Claude API changes
- 05-token-optimization - Token reduction techniques and measurement
- 06-advanced-patterns - Multi-agent coordination, Agent Teams (v2.1.32+), checkpoint systems, constitutions, selective deep plan analysis, session observability
- 07-custom-commands - Ready-to-use slash commands (debug, i18n, qa, seo, deploy, refactor, perf)
- 08-ui-ux-development - UI/UX implementation workflow with browser testing via Chrome MCP
- 09-laravel-mcp-integration - Laravel Boost + LaraPlugins.io MCP setup, CLAUDE.md template for Laravel projects
- 10-subagents - Custom subagent creation (YAML frontmatter format with model/tools/mcpServers fields)
- 11-mobile-development - iOS, Android, React Native, Flutter guides with MCP servers, subagents, CLAUDE.md templates, and cross-platform skills
- 12-desktop-development - macOS, Tauri, Electron guides with MCP servers, subagents, CLAUDE.md templates, and cross-platform skills
- 13-security-hardening - MCP CVEs, vetting checklists, prompt injection defense hooks, production safety rules, permissions.deny templates
- 14-webmcp - WebMCP (W3C Draft) integration guide: navigator.modelContext API, browser tool registration, Chrome/Playwright MCP integration
- 15-context-mode - context-mode MCP plugin: sandbox tool output to protect context window, session continuity after compaction, tool hierarchy (ctx_batch_execute → ctx_search → ctx_execute)
- 16-autonomous-agents - Running Claude Code unattended: cron journaling agents, heartbeat watchdog protocol, watchdog detection patterns, /loop usage, heartbeat template + session-summary Stop hook
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.

ai-prompts CLAUDE.md is an instructions file published in the GitHub repository escapeboy/ai-prompts (91 stars, last pushed 15d ago), licensed MIT. It adds 1,330 tokens to every session, about $0.0053 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
