enum-normalize-over-legacy-data

enum-normalize-over-legacy-data is a skill for Claude Code from maxrave-dev/kotlin-footguns. It costs 109 tokens per session (1,925 once invoked), scanned A, original, GPL-3.0.

A data-compatibility pattern for reading type labels from a remote source when older locally stored rows use different labels. It keeps unknown and missing values distinct from known values.

In plain words
What is it for?
Use it when comparing enum-like type markers from an API with data saved by earlier app versions.
Why use it?
It prevents old data or missing fields from being silently treated as a valid default.

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

enum-normalize-over-legacy-data 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 5d 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 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.
