# Asgard Skills Open-source **263 coding agent skills** knowledge base, categorized into 21 themes. Each skill is an independent Markdown file (`SKILL.md`), following the [Claude Agent Skills](https://docs.claude.com/en/docs/claude-code/skills) specification, with some including pure Python scripts for deterministic calculations. [English](README.en.md) ## Overview This repository is the **raw material library** for the [Asgard AI Platform](https://github.com/asgard-ai-platform). Skills are combined with [Asgard MCPs](https://github.com/orgs/asgard-ai-platform/repositories?q=mcp-) to package into [coding agent plugins](https://github.com/asgard-ai-platform) tailored to specific user scenarios (e.g., Taiwan stock analysts, e-commerce operations, policy researchers). Each skill encapsulates a **methodology + judgment + pitfalls** for a specific task - things that LLM agents would otherwise have to rediscover or get wrong without prompting. ## Repository Structure ``` . ├── {category}-{skill-name}/ │ ├── SKILL.md ← Level 1 frontmatter + Level 2 guidance │ ├── examples/ ← (required, filled as needed) │ ├── references/ ← (lengthy content linked here) │ └── scripts/ ← (only present if deterministic calculation scripts exist) └── ... ``` ## Categories (21 prefixes, 263 skills) | Prefix | Quantity | Theme | |--------|----------|-------| | `grad-` | 87 | Graduate-level theoretical models (RBV, CAPM, SEM, DID…) | | `algo-` | 62 | Algorithms (PageRank, BM25, ARIMA, EOQ…) | | `biz-` | 22 | Business school frameworks (SWOT, Porter's Five Forces, DCF…) | | `hum-` | 9 | Humanities / critical thinking | | `tw-` | 9 | Taiwan local knowledge (stock market, taxation, electronic invoicing…) | | `ecom-` | 7 | E-commerce practices | | `econ-` | 6 | Basic economics | | `meta-` | 6 | Cross-disciplinary thinking models | | `ops-` | 6 | Business operations (OKR, contract review, pitch deck…) | | `law-` | 5 | Legal frameworks | | `pr-` | 5 | Public relations / brand communication | | `cs-` | 4 | Customer service | | `data-` | 4 | Data analysis | | `mfg-` | 4 | Manufacturing | | `mkt-` | 4 | Digital marketing | | `soc-` | 7 | Social sciences | | `stat-` | 4 | Statistical methodologies | | `tech-` | 4 | General technology (API, prompt engineering, MCP server…) | | `ux-` | 4 | Design / UX methodologies | | `fin-` | 2 | Financial practices (modeling, earnings) | | `xborder-` | 2 | Cross-border e-commerce | ## Tool List <details> <summary><b><code>grad-</code></b>　Graduate Level Theoretical Models (87)</summary> -

**Financial**: `biz-cac-ltv`, `biz-breakeven`, `biz-dcf`, `biz-dupont`, `biz-financial-ratios`, `biz-unit-economics`, `grad-capm`, `fin-modeling` - **Risk / Statistics**: `algo-risk-altman-z`, `algo-risk-var`, `mkt-ab-testing`, `algo-mfg-cpk` - **Supply Chain**: `algo-sc-eoq`, `algo-sc-safety-stock`, `algo-sc-newsvendor` - **Ranking**: `algo-rank-wilson`, `algo-rank-elo`, `algo-rank-bayesian` - **E-commerce**: `ecom-rfm-analysis`, `algo-price-elasticity` - **Search**: `algo-seo-tfidf`, `algo-ecom-bm25` Each script supports `--help`, `--input <json>`, and `--verify` (built-in self-testing). Output is printed to stdout in JSON format for easy subsequent connection. ```bash # Example python ecom-rfm-analysis/scripts/rfm_score.py --input customers.json python biz-cac-ltv/scripts/cac_ltv.py --marketing-cost 100000 --new-customers 500 \ --arpu 50 --gross-margin 0.70 --monthly-churn 0.05 ``` ## Design Principles 1. **Iron Law**: Each skill defines a non-obvious constraint that agents will trip over if not prompted. 2. **Hub-and-Spoke**: SKILL.md is concise (< 200 lines); lengthy content is outsourced to `references/`. 3. **Phase-Gate** (algorithm): Clear steps, with verification gates between steps. 4. **Experience-based verification**: Examples must be precisely calculable, not accepting "roughly in a certain range". 5. **No excessive teaching**: Assume agents have basic knowledge, emphasizing areas where they are likely to **make mistakes**. Complete design rules and quality standards can be found in [`CLAUDE.md`](CLAUDE.md). ## Status | Phase | Status | |-------|:-:| | Phase 1: 4 sections with 263 skills generated | ✅ | | Phase 1.5: Automatic linting (frontmatter, length, IRON LAW) | ✅ 263/263 | | Phase 1.7: With/without skill evaluation (4 samples) | ✅ 4/4 with_skill wins | | Phase 2-3: Quality audit (sampling 28) | ✅ 14 PASS / 13 MINOR / 1 MAJOR | | Phase 3.5: P0 + P1 repair | ✅ | | Phase 4: Description optimization (phantom trigger) | ✅ | | Tier 1 + 2 deterministic scripts (total 20) | ✅ All pass `--verify` | | Plugin packaging (Phase 5) | 🟡 Planned ([see `TODO.md`](TODO.md)) | ## Related Repositories - [`asgard-ai-platform/skill-template`](https://github.com/asgard-ai-platform/skill-template) — Template for building coding agent plugins - [`asgard-ai-platform/mcp-*`](https://github.com/orgs/asgard-ai-platform/repositories?q=mcp-) — MCP servers (data sources) - Plugin bundles (coming soon) — Skills + MCPs combinations for specific scenarios ## License MIT License.
