cert-classification-rule

cert-classification-rule is a skill for Claude Code, Codex from jl-cmd/claude-dev-env. It costs 91 tokens per session (2,938 once invoked), scanned A, original, MIT.

A procedure for sorting Samsung Galaxy Store certification rejections into categories such as fixable, unfixable, mixed, or Fold-related.

In plain words
What is it for?
Use it to add or change rules that decide where certification-rejection folders belong.
Why use it?
It keeps rejection handling consistent and prevents each case from being classified by guesswork.

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

cert-classification-rule 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/resort_cert_folders.py), 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 — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cert-Failure Classification Rule

Add or change how a Samsung Galaxy Store certification rejection is sorted into one of four buckets: Fold, unfixable, mixed, or fixable. A rejection lands in a bucket from its must-fix issue titles plus a Fold device check, and the bucket decides which subfolder holds the theme folder.

Contents

When to use

Use this skill when the user asks to:

  • add a fixable item, add an unfixable item, or add a mixed item
  • mark a rejection unfixable, or classify a cert rejection
  • add a cert rule

Almost every such request is one new unfixable title pattern plus its paired test. The fixable and mixed buckets are not configured by hand (see the model below), so a request to "add a fixable item" usually means "stop treating this title as unfixable" or "confirm this title stays fixable with a guard test".

When a title pattern cannot help

If the rejection's only unfixable cue lives in the report description (the L_TESTRESULT text, for example *Not Identifiable) and no must-fix title carries it, stop and tell the user this exact point:

This rejection's only unfixable signal is in the report description, not a must-fix title. The classifier reads titles only, so no pattern here will catch it — teaching it to read the description is a code change to the classifier, not a config rule.

Procedure checklist

Copy this and check each item off as you go:

  • Confirm the unfixable cue is in a must-fix title, not only the description (see Gotchas).
  • Append the new {pattern, label, review_note} after the Gallery entry in unfixable_patterns.json.
  • Add a paired production-path test: the live title classifies as unfixable, plus a negative guard for an out-of-scope title.
  • Run the tests from the shared_utils directory and confirm green.
  • Re-sort the affected day folders with the re-sort recipe (dry run first, then --apply).

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.

cert-classification-rule is a skill published in the GitHub repository jl-cmd/claude-dev-env (5 stars, last pushed today), licensed MIT. It adds 91 tokens to every session and 2,938 once invoked, about $0.0005 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 2026-08-31.
