Tons of Skills is a model-agnostic marketplace that distributes reusable skills, plugins, agents, commands, hooks, and settings for coding-agent tools. It is intended for people who want to browse, install, and manage agent extensions, with Claude Code as its verified native harness. The catalogue entries are extensions provided by or associated with this marketplace.
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.

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 | $0.00005 | $0.01270 |
| Opus 5 | $0.00003 | $0.00635 |
| Sonnet 5 | $0.00001 | $0.00254 |
| Haiku 4.5 | $0.00001 | $0.00127 |
Grade A, and why
roi 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 9d 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.

ROI Calculation Framework
Current State Costs (Annual)
Labor Costs:
- Hours per week: [X]
- Hourly rate: $[X]
- Annual cost: Hours × Rate × 52 = $[X]
Error Costs:
- Error rate: [X]%
- Cost per error: $[X]
- Annual error cost: $[X]
Opportunity Costs:
- Lost revenue due to delays: $[X]
- Missed opportunities: $[X]
Total Annual Cost: $[X]
Automation Solution
Implementation Costs:
- Agency fees: $[X]
- Software licenses: $[X]/year
- Training: $[X]
- Total implementation: $[X]
Annual Operating Costs:
- Software licenses: $[X]
- API costs: $[X]
- Maintenance: $[X]
- Total annual operating: $[X]
ROI Calculation
Time Savings:
- Current time: [X] hours/week
- After automation: [X] hours/week
- Time saved: [X] hours/week
- Annual hours saved: [X] × 52 = [X]
- Value of time saved: [X] × $[rate] = $[X]
Quality Improvements:
- Error reduction: [X]%
- Annual error savings: $[X]
Speed Improvements:
- Faster processing: [X]%
- Additional capacity: $[X]
Total Annual Benefit: $[X]
Net Annual Benefit: $[X] - $[X] operating = $[X]
ROI: (Net Benefit / Implementation Cost) × 100 = [X]%
Payback Period: Implementation Cost / Net Annual Benefit = [X] months

2. Begin implementation (Week 1)
3. See first results (Week 8)
4. Full ROI realized (Month X)
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.

roi is a command published in the GitHub repository jeremylongshore/tons-of-skills-marketplace (2,717 stars, last pushed today), licensed MIT. It adds 5 tokens to every session and 1,270 once invoked, about $0.0000 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.
