Claude Skills by Prism-Shadow

Use when developing PenguinHarness itself — changing packages/{core,server,web,cli,desktop,landing,docs,skills}, the built-in model catalog, the installers or the release workflow; writing or auditing changelog entries; writing a blog post or capturing release screenshots; deciding what to do about data already on disk; or auditing prose that reads like a leaked authoring session. Covers the two-repo symlink layout, the CI-parity verification chain, the record-and-ship contract, where blog me...

Use when changing the PenguinHarness Web App (`packages/web`) — adding or restyling any UI, picking a status colour, adding an icon, laying out a row or a form field, writing user-facing copy, or building a popup. Covers the semantic tone tokens, the icon size/stroke/gap scale, the semantic-versus-formatting rule for explanatory text, the two-dictionary i18n contract, and the portal-panel pattern with its Esc and scroll caveats.

Use when standing PenguinHarness up to try a change by hand — launching the Web App, the desktop shell, the landing page or the docs site to click through it, screenshot it, or reproduce a report. Covers the four dev entry points and their ports, which data root each writes to, and the four ways a healthy setup looks broken.

- **Date:** 2026-08-04 - **Type:** feature - **Scope:** `skills`, `docs` - **PR:** [#195](https://github.com/Prism-Shadow/penguin-harness/pull/195) [中文版](2026-08-04-skill-porting-library-skill.zh.md) New library skill `skill-porting` (agent-tuning group) teaching an agent to bring skills in from the outside world and land them correctly in `agent_state/skills/<name>/`. Its schema tables were verified by directly fetching each source on 2026-08-04 — the skill says so and treats the live JSON a...

- **Date:** 2026-08-11 - **Type:** feature - **Scope:** `skills` - **PR:** [#256](https://github.com/Prism-Shadow/penguin-harness/pull/256) [中文版](2026-08-11-humanizer-skill.zh.md) `humanizer` joins the built-in library under the Office Productivity group as a manual-install skill — `preinstall: false`, so it stays out of default_agent's preinstalled set and installs from the Skill Library on demand ([#256](https://github.com/Prism-Shadow/penguin-harness/pull/256)).

- **Date:** 2026-08-21 - **Type:** refactor - **Scope:** `skills`, `web`, `docs` - **PR:** [#400](https://github.com/Prism-Shadow/penguin-harness/pull/400) - **Breaking:** yes — the library Skill `agent-creation` no longer exists under that name [中文版](2026-08-21-agent-initialization-skill.zh.md) The Agent Tuning group's `agent-creation` Skill is now **`agent-initialization`**. The name says what it does: it initializes an Agent's settings — AGENTS.md, identity metadata, and the Skills that Ag...

- **Date:** 2026-08-23 - **Type:** process - **Scope:** `skills`, `docs` - **PR:** [#428](https://github.com/Prism-Shadow/penguin-harness/pull/428) [中文版](2026-08-23-manual-test-skill.zh.md) `.agents/skills/penguin-harness-manual-test/SKILL.md` is a new repo-development skill covering how to bring the app up on a developer machine so a change can be tried by hand: the four dev entry points (`pnpm dev`, `pnpm desktop`, `pnpm dev:landing`, `pnpm dev:docs`) with their fixed ports, and the environ...

- **Date:** 2026-08-25 - **Type:** feature - **Scope:** `skills`, `docs` - **PR:** [#463](https://github.com/Prism-Shadow/penguin-harness/pull/463) [中文版](2026-08-25-penguin-orchestration-skill.zh.md) Added `penguin-orchestration` (v1) to the skill library's AI App Development group, right after `penguin-cli`. It teaches an agent running inside PenguinHarness to drive the harness itself over the `penguin` CLI against its own local server: list and create agents, start sessions and steer them m...

Run one specified Test Agent on one specified Benchmark Case exactly once, privately score that execution, and return one protocol result.

Initialize an Agent's settings from a user requirement by writing AGENTS.md, setting identity metadata, and installing only needed Skills.

Improve an Agent State through versioned scores and score-linked Traces from a frozen Benchmark.

Call model APIs through @prismshadow/agenthub — streaming text generation, image generation, speech synthesis, embeddings and the supported-model registry with one client.

Design and calibrate a multi-Case capability Benchmark and establish a traceable Formal Baseline.

Create and edit Bento presentations — self-contained .bento.html decks whose document is JSON. Use whenever the user wants a slide deck or presentation: from scratch, from source material, or by improving an existing file.

Complete data-analysis tasks with bounded inspection, correct data semantics, native artifact handling, complete delivery, and risk-based verification.

Search the web and scrape pages into clean markdown with the Firecrawl API — query-based discovery, single-URL extraction including public PDFs, driven by curl with a vault-stored API key.

Rewrite or edit prose in any language so it reads like edited human writing in the register of books, newspapers and encyclopedias rather than default AI output. A small drafting core — vary every pattern, build density from anchored facts in whole grammar, cap the quotables, put a real writer with real material behind the text, let structure serve content, write each language from inside its idiom and typography, verify what you assert, and aim for the natural distribution of edited prose ra...

Fine-tune LLMs with LlamaFactory — register datasets, train via YAML configs, merge LoRA adapters and serve the result.

Deploy and serve local models with Ollama — pull and run them, then expose the OpenAI-compatible endpoint to apps and agents.

Manage model API keys, default models and per-agent vault secrets with the penguin CLI.

Drive PenguinHarness itself from a shell — list and create agents and sessions, send and steer messages mid-flight, and query costs and scheduled tasks via the penguin CLI over the local server.

Use whenever the user wants to build an agent application — their own program with an embedded agent, such as an AI app, an agentic app or a RAG app. This is writing application code on the Penguin Harness SDK, not configuring an Agent State inside PenguinHarness. Covers self-contained projects, the createSession/run streaming loop with thinking and image messages, wiring the user's existing tools in as CLI commands, and a complete RAG recipe that ingests documents into a knowledge base and a...

Run Claude Code on a remote host over SSH — a persistent expect-driven login session, headless claude -p with the stdin fix, the interactive TUI inside a remote tmux driven by send-keys/capture-pane (one keystroke at a time, capture-verified; relayed user messages go through verbatim), and multi-turn continuity via --session-id/--resume or stream-json; hosts and credentials are placeholders resolved at runtime from the user or the vault, never hardcoded.

Install skills from external ecosystems into this agent's agent_state/skills/ — resolve Claude Code plugin marketplaces, the Codex plugin repo, skills.sh registry names, GitHub repos, or local folders to their skill directories, review every file, and normalize SKILL.md frontmatter to the Penguin format.

Complete software-engineering tasks — investigate and review code, implement bug fixes, features and refactors with minimal scope, validate changes, and report verified outcomes.

Deploy and serve LLMs with vLLM behind an OpenAI-compatible endpoint, with tool calling enabled for agent workloads.

Penguin visual language for generated web pages and app UIs — GitHub-style simplicity with a single blue accent, light and pure-black dark themes, design tokens, component and chat-interface recipes, plus an opt-in warm paper editorial theme.

Guidance for using the AgentHub Python SDK (`agenthub-python`). Use when developing agents that call different LLM APIs, need a unified interface for LLM providers, mention AgentHub, request `agenthub-python`, or already import it.

Guidance for using the AgentHub TypeScript SDK (`@prismshadow/agenthub`). Use when developing agents that call different LLM APIs, need a unified interface for LLM providers, mention AgentHub, request `@prismshadow/agenthub`, or already import it.

Fixed workflow for developing AgentHub itself — adding or updating model support. Use when asked to support a new model or protocol version in this repository, sync llmsdk_docs, or implement a provider client. Covers doc syncing, live API capture, paired Python/TypeScript implementation, and model-scoped e2e testing.
