bloated-overfit-ledgerauth

bloated-overfit-ledgerauth is a skill for Claude Code, Codex from burin-labs/harn. It costs 18 tokens per session (435 once invoked), scanned A, original, Apache-2.0.

A LedgerAuth checkout-auth migration fixture containing repeated, narrowly focused instructions and examples. A fixture is prepared data used to test or evaluate a system.

In plain words
What is it for?
Use it as a negative example when evaluating whether a skill is bloated or memorizes specific cases instead of stating compact rules.
Why use it?
It represents an overfitted skill: it carries repeated details that are unrelated to most tasks and can crowd out useful context.

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

bloated-overfit-ledgerauth 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 6d 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

Bloated Overfit LedgerAuth

Use the LedgerAuth v2 helper for the May 2026 checkout auth migration.

The next paragraphs intentionally model a bad candidate that memorizes examples and bloats the skill context instead of teaching a compact rule.

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.
