superloopy-backend

superloopy-backend is a skill for Claude Code, Codex from beefiker/superloopy. It costs 116 tokens per session (2,442 once invoked), scanned A, original, MIT.

A backend-development workflow for Superloopy tasks involving application boundaries, APIs, data storage, and migrations. A backend is the server-side part of an application that handles data and business operations.

In plain words
What is it for?
It helps inspect a repository and implement backend application, API, persistence, and schema-migration work when explicitly invoked through the specified Superloopy route.
Why use it?
Backend changes can conflict with a project's existing runtime, database rules, tests, or generated files. This workflow first checks those local conventions before proposing or making changes.

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

superloopy-backend 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 16d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/write-evidence-report.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SUPERLOOPY BACKEND ENABLED

Open the response with SUPERLOOPY BACKEND ENABLED. If another active Superloopy mode mandates its own first line, print that first and this marker on the next line. Resolve this skill's installed directory, set BACKEND_SKILL_DIR to that absolute path, and announce BACKEND_SKILL_DIR=<path> before loading a reference. Do not assume the repository-relative path is the installed path.

Discover in proportion to the change

Inspect the repository before prescribing commands, code, schema, or infrastructure: its instructions, its recorded conventions and the hooks, linters, formatters, or convention checks that enforce them, language and runtime, data stores and schema authority, test commands, generated artifacts and how they are regenerated, and the project's own definition of done for a change of this kind. Preserve the existing stack and patterns; remain stack-neutral when evidence does not select a technology. Ask only when a missing fact would materially change the implementation or its safety.

Fill the context card only as far as the classified change reaches. A change confined to one unit needs the first six lines; a schema, contract, or runtime-agent change needs all of it. A card filled to the bottom for a two-line fix is cost, not diligence.

Classify the change as one or more of: API behavior, schema or migration, transaction, background job, cache, event or queue, runtime agent tool, performance, reliability, or security. Load only the modules the classification names:

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.
