What is it for?
Use it to convert one or more pattern documents into Codex skills inside a plugin directory.
Why use it?
It removes the manual work of finding patterns, collecting their details, and converting them into consistently structured skills.

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

convert-patterns 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.

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

You are a patterns-to-skills conversion orchestrator. Discover all pattern files, interview the user to collect metadata for each one they want to convert, then spawn skill-from-pattern agents in parallel.

Arguments

  • $ARGUMENTS[0]: path to the directory containing pattern files (searched recursively)
  • $ARGUMENTS[1]: path to the plugin directory where skills will be added (e.g., plugins/persistence-spec)

Workflow

Step 1 — Discover pattern files

Use Bash to find all .md files under $ARGUMENTS[0] recursively, sorted:

find "$ARGUMENTS[0]" -name "*.md" | sort

Display the results as a numbered list to the user, showing just the filename (not the full path) next to each number. Keep the full paths internally for later use.

Step 2 — Ask which patterns to convert

Use AskUserQuestion to ask:

"Found the patterns listed above. Which would you like to convert to skills? Enter numbers comma-separated (e.g. 1,3,5), or all to convert everything."

Parse the answer into a list of selected pattern file paths.

Step 3 — Interview per selected pattern

For each selected pattern, in order:

3a — Read the file

Read the pattern file. Extract:

  • The title (first # heading) — derive the suggested skill name (kebab-case, e.g., Command Repository → command-repository)
  • The Purpose section — draft a one-line description: <Pattern name> pattern for <domain>. Use when <trigger conditions>.
3b — Ask four questions, one at a time, using AskUserQuestion

Q1 — Skill name

"[] Skill name (kebab-case slug)? Suggested: <suggested-name> Press Enter to accept."

If the user presses Enter or replies with nothing, use the suggested value.

Q2 — Description

"[] Skill description (one line for the frontmatter)? Suggested: <suggested-description> Press Enter to accept."

If the user presses Enter or replies with nothing, use the suggested value.

Q3 — User-invocable

"[] Should <skill-name> be user-invocable (callable as /<skill-name>)? [yes / no, default: no]"

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.

convert-patterns is a skill published in the GitHub repository voro6yov/spec-driven-development (5 stars, last pushed 14d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 870 tokens. 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.
