claude-cost-optimizer: Instructions file for Claude Code

CLAUDE.md

claude-cost-optimizer CLAUDE.md is an instructions file for Claude Code from Sagargupta16/claude-cost-optimizer. It costs 1,264 tokens per session, scanned A, original, MIT.

A set of project instructions for an installable Claude Code skill that helps reduce usage costs. It describes the skill, plugin copies, optimization guides, benchmarks, templates, and related project files.

In plain words
What is it for?
Maintaining the cost-optimization skill, its plugin packaging, documentation guides, benchmark data, templates, and marketplace registration.
Why use it?
It gives agents a consistent structure for developing and distributing cost-saving guidance. It also identifies where instructions, measurements, and reusable examples belong.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions .claude-plugin; mentions CLAUDE.md.

This is Sagargupta16/claude-cost-optimizer's own configuration. It tells Claude Code how to work on claude-cost-optimizer 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 claude-cost-optimizer configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is - Root [`CLAUDE.md`](../../CLAUDE.md) -- voice, rules, routing map, references, skills, slash commands, 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.

Security

Grade A, and why

claude-cost-optimizer 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 2d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md - claude-cost-optimizer

This file stacks on top of the workspace root at C:\Code\GitHub\:

  • Root CLAUDE.md -- voice, rules, routing map, references, skills, slash commands, conventions.
  • Root MEMORY.md -- live facts across repos.
  • Root STATUS.md -- live PR/CI/security dashboard.
  • .claude/resources/ -- deep reference for collaboration, workflow, git, OSS, debugging, voice.

Read those first. The guidance below only adds repo-specific context -- it does not override anything in the root.

Purpose

This repo is an installable Claude Code skill and a documentation/tooling project for reducing Claude Code costs. Install: npx skills add Sagargupta16/claude-cost-optimizer.

File Structure

  • skills/cost-mode/ - The installable skill; SKILL.md is the source of truth
  • plugins/, .claude-plugin/, .agents/plugins/ - Distribution copies and registries
  • guides/ - Deep-dive guides 00-11 + diagrams.md
  • benchmarks/, templates/, cheatsheet.md - Measurements, configs, quick reference
  • tools/ - 8 CLI tools; see tools/README.md for the list
  • hooks/ - Budget-enforcement and cost-logging hooks (wired up in .claude/settings.json)
  • site/ - React + Vite + TS site (calculator, badge checker, analyzer) on GitHub Pages
  • case-studies/ - Submission template only; no stories published yet
  • docs/pricing-data.md - Pricing source of truth; docs/pricing-reference.md - the user-facing pricing tables and migration notes (moved out of the README)
  • docs/diagrams/ - The README's toolkit map: orrery spec toolkit.yaml and the light/dark SVGs rendered from it; re-render after adding or moving a tool
  • scripts/ - Consistency checks run by CI (check-rate-values.py compares every code copy of the rates against rate.py), plus capture-screenshots.py for the README images and the social preview
  • Tests: site/src/utils/*.test.ts (vitest, npm test), tools/claude-rate/tests/ (unittest), tools/mcp-cost-server/test/ (node:test over stdio)

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.
