What is memex CLAUDE.md?

A set of operating rules for AI coding agents working in the memex repository. It defines permitted file and infrastructure actions, including when Terraform, AWS commands, commits, and pushes need approval.

Use it to guide safe work in the repository, especially Terraform plans, AWS read-only checks, file edits, and Git operations such as committing or pushing.

It reduces the chance that an agent will make destructive infrastructure or repository changes without the user’s knowledge. It also sets boundaries for what the agent may inspect or edit.

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	$0.03556	$0.03556
Opus 5.5	$0.01422	$0.01422
Sonnet 5.5	$0.00711	$0.00711
Haiku 4.5	$0.00356	$0.00356

Security

Grade B, and why

memex CLAUDE.md scanned grade B with 1 finding 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 1mo 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- For new timer units: `sudo systemctl start <unit>` succeeds, then `systemctl is-active` reports OK

CLAUDE.md — Rules for AI agents working in this repo

This file is auto-loaded by Claude Code (and other AI coding agents that honor the convention). It defines the safety and scope rules every agent must follow when editing this codebase.

What you are allowed to do

Read files and understand the codebase.
Edit config, scripts, and docs when explicitly asked.
Run terraform plan and make audit to show what would change.
Run AWS CLI read-only commands (describe, list, get).
Commit and push ONLY when explicitly asked.

What you are NOT allowed to do without explicit confirmation

Destructive infrastructure changes

NEVER run terraform apply without showing the plan first AND getting explicit "yes, apply".
NEVER destroy or replace running EC2 instances without explicit confirmation.
NEVER change availability zones, instance types, or subnet configurations without warning.
If a terraform plan shows ANY resource being destroyed or replaced — STOP and ask first.

File and git operations

NEVER run git reset --hard or any destructive git command.
NEVER commit files that were not explicitly included in the request.
NEVER stage and commit deleted files unless explicitly asked to remove them.
Disk files and git files are DIFFERENT — do not confuse them.

Scope of work

Do ONLY what was asked. If asked to fix a config file, fix that file only.
Do NOT remove integrations, features, or code that was not mentioned.
Do NOT "clean up" things that look unused — ask first.
Do NOT add, remove, or modify terraform resources beyond what was asked.
Do NOT add monitoring, alarms, notifications, health checks, dashboards, or any new AWS infrastructure that the user did not explicitly request, even if it would "improve reliability" or "catch the next failure". Discuss the idea in plain text first, agree on the approach, and only then build.

Key principle

Ask before acting on anything irreversible. The cost of one confirmation message is zero. The cost of a destroyed EC2 instance or lost disk data is high.

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.

memex CLAUDE.md is an instructions file published in the GitHub repository timurgaleev/memex (11 stars, last pushed 1mo ago), licensed MIT. It adds 3,556 tokens to every session, about $0.0142 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
