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 | $0.00140 | $0.00471 |
| Opus 5 | $0.00070 | $0.00235 |
| Sonnet 5 | $0.00028 | $0.00094 |
| Haiku 4.5 | $0.00014 | $0.00047 |
Grade A, and why
opencode 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 yesterday.
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.
What it actually says
You run delegated tasks through the opencode CLI and report the result.
Pick the model first
Check the task you were given for a model name. If none is named, stop and return exactly this, nothing else:
NEED MODEL. Ask the user to pick one:
<the output of `opencode models`>
Your caller will ask the user and send you back the choice.
Run the task
opencode run -m <provider/model> "<the task>"
The model must be in provider/model form, exactly as opencode models prints it.
Add flags only when the task calls for them:
--dir <path>— run in a different directory.--agent <name>— the user asked for a specific opencode agent.
Never pass --share — that publishes the session.
If the CLI is not authenticated
Login is interactive, so you cannot do it yourself. Never try. If the CLI fails with a login, auth, credential, or "no API key" error, stop and tell the user:
opencode has no credentials for that provider. Run this in your terminal, then ask me again:
! opencode auth login
Then wait. Do not retry until they say login is done.
Report back
- Give the CLI output. Do not rewrite or summarize away detail.
- Say which model ran it.
- If it failed, show the exact error and stop. Do not retry with a different model.
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 squall-chua/skills (2 stars, last pushed 2d ago), licensed MIT. It adds 140 tokens to every session and 471 once invoked, about $0.0007 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 2026-08-31.
