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 | $0.01169 | $0.01169 |
| Opus 5.5 | $0.00468 | $0.00468 |
| Sonnet 5.5 | $0.00234 | $0.00234 |
| Haiku 4.5 | $0.00117 | $0.00117 |
Grade A, and why
claude-code-personal-workspace 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 10d 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 — 97 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 personal workspace for Claude Code to assist with various daily tasks including programming, documentation, research, consultation, translation, and generative-AI development.
Package Manager: This workspace uses pnpm 12.14.0, pinned in package.json via packageManager (Corepack). Always use pnpm commands instead of npm; run corepack enable or prefix commands with corepack pnpm if pnpm is not on your PATH.
Context Management
Why Context Management Matters: Quality degrades at 20-40% usage, long before a window is full. The actual window depends on the model (1M tokens by default; set CLAUDE_CONTEXT_WINDOW to override). A UserPromptSubmit hook (.claude/hooks/context_monitor.js) measures real usage from the transcript and injects [Context Monitor] warnings at 20/40/60%, so act on those warnings rather than estimating from message counts.
Best Practices:
-
Scope conversations per feature - One conversation per task/feature prevents context bleeding. Don't build auth and refactor database in the same session.
-
Use external memory - Write plans and progress into the task directory:
tasks/<task-name-yymmdd>/plan.mdandNOTES.md. These persist across sessions, allowing fresh context with preserved knowledge. -
The copy-paste reset - When context gets bloated:
- Copy important info from terminal
- Run
/compactto summarize - Run
/clearto wipe context - Paste back only what matters
-
Know when to clear - If explaining the same thing 3+ times,
/clearand reframe. Fresh context > fighting through degraded context. -
Write plans to a file - For complex tasks, outline the approach in
tasks/<task-name-yymmdd>/plan.md. It survives context resets and keeps the implementation focused.
External Memory Files:
tasks/<task-name-yymmdd>/plan.md- Implementation plan and design decisionstasks/<task-name-yymmdd>/NOTES.md- Progress, findings, and handoff notes
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.

claude-code-personal-workspace CLAUDE.md is an instructions file published in the GitHub repository shino369/claude-code-personal-workspace (3 stars, last pushed 11d ago), licensed ISC. It adds 1,169 tokens to every session, about $0.0047 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 2026-08-31.
