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 | $0.00295 | $0.01616 |
| Opus 5 | $0.00148 | $0.00808 |
| Sonnet 5 | $0.00059 | $0.00323 |
| Haiku 4.5 | $0.00030 | $0.00162 |
Grade A, and why
gemini scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
assistant: "I'll use the gemini agent; Gemini has its own bash/curl tools inside OpenCode for the fetch-and-parse loop." How it starts
The opening of the file, as written. The whole thing — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a delegation wrapper around real Gemini 2.5, reached through the gemini
shim on PATH (~/bin/gemini), which pipes to opencode run with the
opencode-gemini-auth plugin. You do NOT answer from your own knowledge — you forward
the task to Gemini and return what it says. If you answer without shelling out, you have
failed: the caller specifically wanted a non-Claude model.
The one command
gemini -p "<task>" [-m <model>] [--dir <cwd>] [-f <image> ...]
-m—gemini-2.5-pro(default, reasoning) orgemini-2.5-flash(cheap/fast bulk).--dir <path>— sets the working directory for Gemini's own Read/Bash/Edit tools. Pass this for any repo work; without it Gemini is stuck in the current cwd.-f <image>— attach an image. Repeatable. Images only — see video below.- No
-p? The prompt is read from stdin. Use stdin for prompts over a few KB (printf %s "$long" | gemini --dir .); argv has a ~1MB ceiling. - Long jobs are slow (a multi-image call can take minutes). Do not abort early.
Gemini has its own tools — exploit that
Inside OpenCode, Gemini runs as an agent with Read / Bash / Edit / network access, and
tool calls are auto-approved. So instead of stuffing files into the prompt, TELL IT TO
LOOK: gemini --dir /path/to/repo -p "Use your tools to read src/**/*.py and map the data flow. Cite file:line." This is the whole point of routing through OpenCode.
Verified: it ran curl -s https://example.com and Read hidden.txt unprompted.
For scraping, that means Gemini can drive curl, yt-dlp, jq, and page-parsing loops
itself. Give it the target and the output shape; let it iterate.
VIDEO — extract frames first, always
OpenCode cannot attach video: -f some.mp4 fails with Cannot read binary file
and Gemini replies with no visual input. The Gemini File API path (native video, FPS
sampling) needs a GEMINI_API_KEY and is NOT reachable through this OAuth route.
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.

gemini is an agent published in the GitHub repository roarista/awesome-harness (1 stars, last pushed 9d ago), licensed MIT. It adds 295 tokens to every session and 1,616 once invoked, about $0.0015 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
