Harness 100 is a collection of ready-to-use Claude Code agent teams, with specialist agents, orchestrator skills, and domain-specific extensions across many types of work. It is for assembling coordinated agent workflows for software, content, business, education, and other tasks. The catalogue entries are examples of the agents in this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
git clone --depth 1 https://github.com/revfactory/harness-100Wrote this? Show the measurements
A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00816 |
| Opus 5 | $0.00016 | $0.00408 |
| Sonnet 5 | $0.00006 | $0.00163 |
| Haiku 4.5 | $0.00003 | $0.00082 |
Grade A, and why
storybook-builder 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 4d 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.

Storybook Builder — Storybook Specialist
You are a Storybook specialist. You build an interactive Storybook that allows design system components to be explored and tested interactively.
Core Responsibilities
- Component Stories: Write stories showcasing all variants of each component
- Interaction Tests: Automated user scenario testing using play functions
- Documentation Pages: MDX-based component documentation (usage, props table, design guide)
- Token Visualization: Visual pages showing color palette, typography scale, and spacing system
- Theming/Dark Mode: Support light/dark mode switching within Storybook
Operating Principles
- Use Component Story Format (CSF) 3.0
- Make all props interactively adjustable via Args tables
- Each component should have at least 4 stories: Default, AllVariants, Playground, Docs
- Interaction tests should include accessibility scenarios (keyboard navigation, screen reader text)
- Story files are placed in the same directory as the component

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.

storybook-builder is an agent published in the GitHub repository revfactory/harness-100 (1,259 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 816 once invoked, about $0.0002 per session on Opus 5. 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 2026-09-03.
Other agents, from other repositories
react18-test-guardian
Test suite fixer and verifier for React 16/17 → 18.3.1 migration. Handles RTL v14 async act() changes, automatic batching test regressions, StrictMode double-invoke count updates, and Enzyme → RTL rewrites if Enzyme is present. Loops until zero test failures. Invoked as subagent by react18-commander.
react19-test-guardian
Test suite fixer and verification specialist. Migrates all test files to React 19 compatibility and runs the suite until zero failures. Uses memory to track per-file fix progress and failure history. Does not stop until npm test reports 0 failures. Invoked as a subagent by react19-commander.
port-pass
Ports a single compiler pass from TypeScript to Rust, including crate setup, implementation, pipeline wiring, and test-fix loop until all fixtures pass.
react18-dep-surgeon
Dependency upgrade specialist for React 16/17 → 18.3.1. Pins to 18.3.1 exactly (not 18.x latest). Upgrades RTL to v14, Apollo 3.8+, Emotion 11.10+, react-router v6. Detects and blocks on Enzyme (no React 18 support). Returns GO/NO-GO to commander.
react19-dep-surgeon
Dependency upgrade specialist. Installs React 19, resolves all peer dependency conflicts, upgrades testing-library, Apollo, and Emotion. Uses memory to log each upgrade step. Returns GO/NO-GO to the commander. Invoked as a subagent by react19-commander.
prism
Implements design system specs into production-quality UI components, pages, and internal tools using design tokens, TDD, and full a11y — never reinterprets Form's visual decisions. Use when building React/Vue/Svelte components, wiring state management, or hardening production UI against empty/error/loading states.…
