eAI: Instructions file for Claude Code

CLAUDE.md

eAI CLAUDE.md is an instructions file for Claude Code from embeddedos-org/eAI. It costs 1,241 tokens per session, scanned A, original, MIT.

Project instructions for eAI, focused on correct, secure, maintainable, and verifiable software. They define five rules, including reporting only checks that were actually run and stopping when required information is missing.

In plain words
What is it for?
Use them to guide implementation, testing, self-review, and handling blocked work in the eAI repository.
Why use it?
They reduce the risk of agents claiming tests passed, losing acceptance requirements, adding unnecessary changes, or inventing missing details.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is embeddedos-org/eAI's own configuration. It tells Claude Code how to work on eAI 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 eAI configures →

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

eAI 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 2mo 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Rules

Applies to every task in eAI.

Protect this project by producing correct, maintainable, secure and verifiable software. Do not optimise for appearing complete. Optimise for results that can be checked by someone who does not trust you.

The five

Everything else in this standard elaborates on these. If you remember nothing else, remember these.

  1. Never report a check as passing unless you ran it and read the output. NOT RUN is an acceptable answer. A guess dressed as PASS is not.
  2. Carry acceptance criteria verbatim. Summarise anything else. A criterion lost in a handoff is work that silently stops being done while still looking finished.
  3. Make the smallest safe change that satisfies the requirement. Every extra line is surface area you were not asked for.
  4. Whoever implements does not approve. Self-review misses precisely the thing the author already believes is correct.
  5. When blocked, stop and name what is missing. Do not invent a value, an API, or a file to fill the gap and keep moving.

Priorities

When two conflict, the earlier wins.

  1. Correctness
  2. Security
  3. Reliability
  4. Maintainability
  5. Scalability
  6. Performance
  7. Testability
  8. Readability
  9. Consistency with existing architecture
  10. Speed of delivery

Requirements

  • No placeholder code, stubs, or unfinished files.
  • No TODOs unless explicitly requested.
  • Follow the style already in the file.
  • Tests for new behaviour.
  • Documentation updated when behaviour, API or setup changes.
  • State the reasoning behind non-obvious design decisions.

Evidence

Label any load-bearing statement:

  • Verified — evidence exists; a command was run and its output observed.
  • Observed — directly visible in the code or repository.
  • Inferred — a reasonable conclusion drawn from what was observed, not confirmed.
  • Assumed — information is missing and a default was taken.
  • Unknown — cannot be determined from what is available.

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.
