Insomnia CLAUDE.md

A project instruction file for Insomnia, a Windows app that keeps a computer awake while coding tools or selected apps are running. It also defines shared memory and communication rules for AI coding agents working on the project.

In plain words
What is it for?
Guiding agents before non-trivial work, recording meaningful changes, tracking release status, and coordinating work between Claude Code and Codex.
Why use it?
It helps agents understand the current project state and preserve important decisions, fixes, and known risks between sessions.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 B, and why

Insomnia 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 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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Insomnia

Lightweight Windows app (Electron) that prevents the PC from sleeping while AI coding tools (Claude Code, Cursor, Aider, Codex, Ollama) or watched apps are running. Tray icon + manual toggle. Hook-based detection for Claude Code and Codex; process-based for the rest.

Agent Memory Protocol

Use this file as the standing project memory shared between Claude Code and Codex.

Rules:

  1. Read this file before starting non-trivial work so the current architecture, release state, and prior regressions are fresh.
  2. Any meaningful code change, architecture decision, bug fix, regression, release action, or workflow adjustment should be recorded here.
  3. Each note should be prefixed with the agent name in brackets, for example [Claude] or [Codex].
  4. Prefer concise entries that explain what changed, why it changed, and any follow-up risk.
  5. Keep older entries unless they are clearly obsolete; append instead of rewriting history unless the file needs cleanup.
  6. If the file's encoding gets damaged, normalize it back to plain ASCII or valid UTF-8 while preserving meaning.
  7. Keep the Current State section accurate when release status, version, detection behavior, or known limitations change.

Agent Communication Protocol

Use this section as the shared communication contract for Claude Code, Codex, or any other coding agent working in this repo.

Rules:

  1. Start by checking git status, reading this memory file, and identifying the active branch before making edits.
  2. Preserve user work. Do not revert unrelated dirty files or generated outputs unless the user explicitly asks.
  3. Before edits, state what you are about to change and why. While working, share concise progress updates when the task takes more than a quick command.
  4. When blocked, report the blocker, what was already tried, and the safest next option instead of silently changing direction.
  5. Before finishing, summarize changed files, verification performed, and any remaining risk or follow-up.
  6. If a change affects behavior, release workflow, installer output, hooks, or package manager metadata, add an Agent Log entry.

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.

Insomnia CLAUDE.md is an instructions file published in the GitHub repository stanley-projects/Insomnia (2 stars, last pushed 3mo ago), licensed MIT. It adds 2,990 tokens to every session, about $0.0149 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
