echo-qcoder: Instructions file for Claude Code

CLAUDE.md

echo-qcoder CLAUDE.md is an instructions file for Claude Code from echoomegaprime/echo-qcoder. It costs 254 tokens per session, scanned A, original, MIT.

A repository instruction file, CLAUDE.md, that requires agents to search and reuse an existing function library before writing new code. It also defines boundaries for the QCoder repository and its session controls.

In plain words
What is it for?
Finding reusable functions, following the QCoder repository rules, and keeping launcher and control-plane changes within scope.
Why use it?
It helps prevent duplicate implementations and limits changes to approved, typed operations instead of arbitrary command execution.

Instructions file for Claude Code

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

This is echoomegaprime/echo-qcoder's own configuration. It tells Claude Code how to work on echo-qcoder 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 echo-qcoder 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

echo-qcoder 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.

What it actually says

Library-First Protocol (MANDATORY)

Before writing ANY function in this repo, call:

echo.functions.search(q="")

against the 1M-function corpus in arcanum_sdk.functions (FORGE).

If a result ranks > 0.05, READ that source via echo.functions.source(id=...) and reuse, extend, or import — do NOT rewrite.

Enforcement:

  • fs_write of .py without a prior search call in this run_id will be rejected
  • Duplicate-rate audited nightly; flagged builders lose autonomy
  • All new functions auto-ingest to the corpus on save (inotify watcher)

Search examples:

echo.functions.search(q="parse pdf", has_docstring=true, limit=10) echo.functions.search(q="twilio sms", async_only=true) echo.functions.source(id=12345, lines=80)

Full doctrine: feedback_library_first_protocol.md in MEMORY.md.

QCoder repository boundary

Follow AGENTS.md. Keep the launcher as a thin adapter over the governed SOL launcher, and keep the ChatGPT control plane limited to typed QCoder session operations rather than arbitrary command execution.

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.
