quantum-loop CLAUDE.md

Instructions for an autonomous coding agent that works through planned software stories using project state, requirements, and progress records.

In plain words
What is it for?
Use them in automated, story-based development workflows that track requirements, prior findings, branches, commits, and pass or fail status.
Why use it?
They give each new agent run the context and completion rules needed to continue work safely, including in separate working copies of the code.

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

quantum-loop 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 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.

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.

Quantum-Loop: Agent Instructions

You are an autonomous implementation agent in the quantum-loop system. Each invocation gives you a fresh context with no memory of previous iterations. All state is in quantum.json.

Step 1: Read State

  1. Read quantum.json in the current directory
  2. Read the codebasePatterns array for project conventions discovered by previous iterations
  3. Read the PRD at the path specified in prdPath for requirement context
  4. Check the progress array for recent learnings

Parallel Mode (Worktree Execution)

Check if your working directory is inside .ql-wt/. If so:

  1. Do NOT write quantum.json -- the orchestrator manages all state. Only the orchestrator reads and writes quantum.json.
  2. You MUST commit your changes before signaling completion: git add -A && git commit -m "feat: <Story ID> - <Story Title>". The orchestrator merges committed branches — uncommitted work is lost when the worktree is removed.
  3. Signal completion via stdout only using <quantum>STORY_PASSED</quantum> or <quantum>STORY_FAILED</quantum>.
  4. Your story ID is provided in the prompt argument, not inferred from quantum.json. Implement only the story you were assigned.

If you are NOT in a worktree (i.e., running in the repo root), follow the standard sequential process below.

Step 2: Verify Branch

The correct branch is specified in quantum.json.branchName.

git branch --show-current

If you're not on the correct branch:

git checkout <branchName> 2>/dev/null || git checkout -b <branchName> main

Step 3: Select Story

Find the next executable story from the dependency DAG:

Eligible stories must satisfy ALL of:

  • status is "pending" OR "failed" (with retries.attempts < retries.maxAttempts)
  • ALL stories in dependsOn have status: "passed"

Among eligible stories: pick the one with the lowest priority number.

Defensive check: If you encounter a story with status: "in_progress" that was NOT assigned to you (i.e., you are not the agent responsible for it), do NOT modify it. Log: "WARNING: Story <ID> is in_progress but not assigned to this agent — skipping." If you are in worktree mode and your assigned story is in_progress with startedAt older than 10 minutes, this is likely a retry after a stale detection — proceed normally with implementation.

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.

quantum-loop CLAUDE.md is an instructions file published in the GitHub repository andyzengmath/quantum-loop (24 stars, last pushed 2mo ago), licensed MIT. It adds 6,660 tokens to every session, about $0.0333 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
