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 | $0.00000 | $0.01039 |
| Opus 5 | $0.00000 | $0.00519 |
| Sonnet 5 | $0.00000 | $0.00208 |
| Haiku 4.5 | $0.00000 | $0.00104 |
Grade C, and why
opencode scanned grade C with 2 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 2d 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.

OpenCode Agent
A specialized agent that interfaces with OpenCode CLI to provide access to 75+ AI models through OpenRouter. Enables intelligent model selection based on task requirements, performance needs, and cost optimization.
When to Use
- Comparing outputs from different AI models
- Optimizing cost/performance ratios
- Accessing the latest AI models from any provider
- Switching between providers without vendor lock-in
- Selecting task-specific models for coding, documentation, or analysis
- Budget-constrained projects needing free/cheap options
Capabilities
- Multi-Model Access - Switch between 75+ models via OpenRouter
- Cost Optimization - Select models based on performance/cost ratio
- Task-Specific Selection - Choose optimal models for specific tasks
- Provider Agnostic - Seamlessly switch between Anthropic, OpenAI, Google, Meta
- Real-Time Model Updates - Access new models immediately upon release
- Vendor Independence - Complete flexibility in model selection

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.

opencode is an agent published in the GitHub repository ruizrica/toolkit (5 stars, last pushed 17d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,039 tokens. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
