What is claude-skills CLAUDE.md?

A Claude Code project instruction file that uses a memory bank to preserve project context between coding sessions. It lists the memory files to read and sets expectations for planning and code quality.

Use it to initialize Claude Code sessions, read the project’s stored context, follow its development conventions, and review non-trivial changes.

It helps the agent recover the project’s goals, architecture, technical setup, current work, and progress instead of starting without context.

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 5.1	$0.02700	$0.02700
Opus 5.5	$0.01080	$0.01080
Sonnet 5.5	$0.00540	$0.00540
Haiku 4.5	$0.00270	$0.00270

Security

Grade A, and why

claude-skills 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 3d 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.

Project Configuration

This file contains project-specific intelligence and configuration for Claude Code sessions.

Memory Bank System

This project uses a Memory Bank system to maintain context across sessions. All memory files are stored in .claude/memory-bank/ and should be read at the start of every conversation.

Core Memory Files (Read these in order):

memory-rules.md - System documentation
projectbrief.md - Foundation document
productContext.md - Product vision
systemPatterns.md - Architecture patterns
techContext.md - Technical setup
activeContext.md - Current work focus
progress.md - Status tracking

Elegance Demand

For non-trivial changes, pause and ask yourself: is there a more elegant solution? If your plan feels hacky, step back and rebuild it properly. Elegant code is simple, clear, and does not fight the architecture.

If you encounter pre-existing issues in code you're touching, be a good citizen and clean them up too. Leave the codebase better than you found it.

Instructions for Claude

On Every Session Start:

Read all core memory bank files in the order listed above
Verify understanding of current context
Check activeContext.md for immediate priorities
Review progress.md to understand what's complete and what's pending

When User Says "update memory bank":

Review ALL memory bank files (mandatory - don't skip any)
Update files that need changes based on recent work
Pay special attention to activeContext.md and progress.md
Document any new patterns discovered
Update project intelligence in this file if needed

Planning Mode (via /plan command):

Read Memory Bank (automatic)
Verify context completeness
Ask 4-6 clarifying questions based on findings
Draft comprehensive plan
Get user approval
Implement systematically

Project Intelligence

This section grows as patterns and preferences are discovered during work on this project.

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.
