implement-parse-list

implement-parse-list is a skill for Claude Code from zernie/vigiles. It costs 11 tokens per session (118 once invoked), scanned A, original, MIT.

A coding task for implementing a small JavaScript utility named parseList. The function turns a comma-separated string into a list of trimmed items and is exported from src/parse.js.

In plain words
What is it for?
Use it to implement and export parseList in an existing project, using the tests under test/ to check the result.
Why use it?
It gives a precise implementation target when the expected behavior is defined by tests. The tests provide the cases the function must handle.

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

implement-parse-list 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (test/parse.test.js), 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.

What it actually says

Implement parseList

Implement a function parseList(input) in src/parse.js and export it as a named ESM export.

It takes a comma-separated string and returns the list of items:

  • Split the input on commas.
  • Trim surrounding whitespace from each item.

The module must be importable as parseList from src/parse.js. The behaviour is covered by the tests under test/.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
