break-loop

A structured review of a fixed bug that looks for the underlying reason it happened and why earlier fixes may have failed.

In plain words
What is it for?
Use it after debugging to examine missing documentation, unclear boundaries between parts of the system, missed related changes, test gaps, and hidden assumptions.
Why use it?
It helps turn one debugging session into a lasting improvement instead of repeating the same kind of bug.

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,027 The whole file, excluding the scripts and references it only reads on demand.

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

break-loop 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 yesterday.

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.

Break the Loop - Deep Bug Analysis

When debug is complete, use this command for deep analysis to break the "fix bug -> forget -> repeat" cycle.


Analysis Framework

Analyze the bug you just fixed from these 5 dimensions:

1. Root Cause Category

Which category does this bug belong to?

Category Characteristics Example
A. Missing Spec No documentation on how to do it New feature without checklist
B. Cross-Layer Contract Interface between layers unclear API returns different format than expected
C. Change Propagation Failure Changed one place, missed others Changed function signature, missed call sites
D. Test Coverage Gap Unit test passes, integration fails Works alone, breaks when combined
E. Implicit Assumption Code relies on undocumented assumption Timestamp seconds vs milliseconds

2. Why Fixes Failed (if applicable)

If you tried multiple fixes before succeeding, analyze each failure:

  • Surface Fix: Fixed symptom, not root cause
  • Incomplete Scope: Found root cause, didn't cover all cases
  • Tool Limitation: grep missed it, type check wasn't strict
  • Mental Model: Kept looking in same layer, didn't think cross-layer

3. Prevention Mechanisms

What mechanisms would prevent this from happening again?

Type Description Example
Documentation Write it down so people know Update thinking guide
Architecture Make the error impossible structurally Type-safe wrappers
Compile-time TypeScript strict, no any Signature change causes compile error
Runtime Monitoring, alerts, scans Detect orphan entities
Test Coverage E2E tests, integration tests Verify full flow
Code Review Checklist, PR template "Did you check X?"

4. Systematic Expansion

What broader problems does this bug reveal?

  • Similar Issues: Where else might this problem exist?
  • Design Flaw: Is there a fundamental architecture issue?
  • Process Flaw: Is there a development process improvement?
  • Knowledge Gap: Is the team missing some understanding?

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.

break-loop is a command published in the GitHub repository mistydew/tokenicode-deepseek-alpha (367 stars, last pushed 27d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,027 tokens. 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.
