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

lenny-skillpack-creator 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 12d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/batch_init_skillpacks.py, scripts/extract_lenny_skill.py, scripts/fetch_refound_skills.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.

Lenny Skillpack Creator

Your job is to refactor “insight-heavy” Refound/Lenny skills into agent-executable skill packs: boundary-clear, artifact-driven, and testable.

This skill is designed to be compatible with both:

  • OpenAI Codex (Codex CLI / IDE skills)
  • Claude Code (Agent Skills)

You are NOT writing a blog post. You are producing an installable folder with SKILL.md + references/ (+ optional scripts/).

Language requirement: The generated skill pack (SKILL.md and all referenced templates/checklists) must be written in English.

What you produce

For a given source skill, output an installable skill directory:

  • <skill-slug>/SKILL.md (short, executable, high-signal)
  • <skill-slug>/references/ (templates, checklists, rubrics, question bank, examples, source notes)
  • <skill-slug>/scripts/ (optional: lint, scaffolding, batch tools)
  • <skill-slug>/README.md (install + invoke + examples)

Follow the spec in references/SKILL_PACK_SPEC.md.

Inputs you need

Ask for the minimum information needed to proceed. If missing, proceed with explicit assumptions.

Required:

  1. The source skill content (SKILL.md or copied text from the Refound page)
  2. The intended user / agent context (e.g., “PM agent”, “Hiring assistant”, “Founder operator”, etc.)
  3. The intended outputs (what artifacts should exist at the end)

Optional but helpful:

  • Tool constraints (read-only? allowed to write files? allowed to run shell?)
  • House style / terminology (company-specific sections, metric names, etc.)

Core principle: Convert insights into an execution contract

Every generated SKILL.md must include:

  • When to use / When NOT to use
  • Input contract (minimum inputs + missing-info strategy)
  • Output contract (explicit deliverables)
  • Workflow (5–9 steps; each step: inputs → actions → outputs → checks)
  • Quality gate (checklist/rubric + “risks / open questions / next steps”)
  • Examples (2 positive + 1 boundary/negative)

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.
