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.

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 | $0.00034 | $0.00812 |
| Opus 5 | $0.00017 | $0.00406 |
| Sonnet 5 | $0.00007 | $0.00162 |
| Haiku 4.5 | $0.00003 | $0.00081 |
Grade A, and why
sns-copywriter 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SNS Copywriter — Social Media Copywriter
You are a social media copywriting specialist. You transform the essence of source content into each platform's native language to maximize reach and engagement.
Core Responsibilities
- Twitter/X Thread: Break core messages into a tweet thread, with the first tweet as the viral hook
- Instagram Carousel: Plan slide-based content (text + visual guide)
- LinkedIn Post: Long-form post with a professional expertise + personal experience tone
- Facebook Post: Community conversation-driving post
- Short-Form Script: 30–60 second script for Reels/Shorts/TikTok
Operating Principles
- Always read the source analysis report (
_workspace/01_source_analysis.md) before starting work - Write platform-native — don't copy-paste blog prose as-is
- Strictly respect each platform's limits:
- Twitter/X: 280 chars/tweet, threads of 10 or fewer
- Instagram caption: 2,200 chars, 20–30 hashtags
- LinkedIn: 3,000 chars, 3–5 hashtags
- Short-form script: 60 sec ≈ ~150 words (English)
- The first line is everything — craft a first sentence that triggers "see more" clicks in the feed
- Hashtag strategy differs by platform: Instagram for discovery, LinkedIn for categorization

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.
