Skillpack skillpack-creator

Create a reusable SkillPack from a successful completed task. Use when the user wants to convert a one-off research, coding, analysis, or content workflow into a distributable local SkillPack with `skillpack.json`, local skills under `skills/`, starter prompts, start scripts, and an optional zip package.

Skillpack Creator

Overview

Turn a successful task into a reusable SkillPack. Extract the stable workflow, decide what belongs in a local skill versus pack-level prompts, generate the pack structure, and package it only after the workflow is explicit and repeatable.

Workflow

1. Normalize the source task

Reduce the finished task into a clean execution spec:

  • Capture the user goal, concrete deliverable, and the final successful workflow (not the full exploratory transcript).
  • List required skills, tools, files, secrets, and environment assumptions.
  • Separate deterministic steps from heuristic steps; remove dead ends and debugging noise.
  • If the task is still too broad, narrow the scope instead of writing a vague mega-skill. If key success conditions depend on hidden human judgment, mark the pack as a best-effort assistant workflow.

Ask for missing stable facts or infer only the low-risk pieces.

2. Decide what the pack should contain

  • Local skill (
    skills/
    ): reusable procedural knowledge. Keep scripts minimal unless reproducibility depends on exact file generation or repetitive shell steps.
  • Scripts (
    scripts/
    ): repeated shell or file-generation logic where reliability matters.
  • References (
    references/
    ): detailed schemas, API notes, or conventions that should not bloat
    SKILL.md
    .
  • Prompts (
    skillpack.json
    ): 1–3 pack-level starter inputs for the UI — not a DAG or state machine. See
    references/skillpack-format.md
    for exact pack semantics.

3. Create the pack specification

Before writing files, define the pack spec. Prefer one local orchestrator skill plus a small number of external skills. Example minimal manifest:

{
  "name": "company-research",
  "description": "Research a company and produce a summary report",
  "version": "1.0.0",
  "prompts": ["Research {company} and create a report with financials and competitors"],
  "skills": [
    { "name": "research-orchestrator", "source": "./skills/research-orchestrator", "description": "Orchestrate company research across multiple sources" }
  ]
}

4. Create the local orchestrator skill

Create

skills/<skill-name>/SKILL.md
with frontmatter and imperative workflow instructions:

---
name: research-orchestrator
description: "Orchestrate multi-source company research. Use when the user wants a structured company report covering financials, competitors, and market position."
---
  • Write the stable workflow as imperative steps in the body.
  • Add
    scripts/
    only for fragile or repeated operations; add
    references/
    only for detailed information.

5. Materialize the pack

Use

scripts/scaffold_skillpack.py
when you have the pack spec:

# Basic
python3 skills/skillpack-creator/scripts/scaffold_skillpack.py \
  --manifest /tmp/skillpack.json \
  --output /absolute/path/to/output-pack

# With zip
python3 skills/skillpack-creator/scripts/scaffold_skillpack.py \
  --manifest /tmp/skillpack.json \
  --output /absolute/path/to/output-pack \
  --zip

The script validates the manifest, writes

skillpack.json
, creates
skills/
, copies
start.sh
/
start.bat
from
templates/
, and optionally runs
npx -y @cremini/skillpack zip
.

6. Validate the result

Before handing the pack back, confirm:

  • The manifest matches the intended pack scope
  • Every declared skill has a valid
    name
    ,
    source
    , and
    description
  • Local skills are present under the target pack's
    skills/
  • Starter prompts are concrete enough to reproduce the workflow
  • Zip only after the pack runs as a directory

Output Standard

Produce:

  1. A short summary of the stabilized workflow.
  2. The target pack structure and skill inventory.
  3. The created or updated local skill files.
  4. The generated
    skillpack.json
    .
  5. Whether the pack was zipped and where the zip lives.
