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 | $0.00015 | $0.00183 |
| Opus 5 | $0.00008 | $0.00092 |
| Sonnet 5 | $0.00003 | $0.00037 |
| Haiku 4.5 | $0.00002 | $0.00018 |
Grade C, and why
setup 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -fsSL https://opencode.ai/install | bash What it actually says
Run:
node "${CLAUDE_PLUGIN_ROOT}/dist/scripts/opencode-companion.mjs" setup --json $ARGUMENTS
If the result says OpenCode is unavailable:
- Tell the user to install OpenCode with:
curl -fsSL https://opencode.ai/install | bash
If OpenCode is installed but credentials are missing:
- Tell the user to run:
opencode providers login
If setup is ready:
- Present the setup output clearly.
- Preserve review gate state and any next steps.
Do not install OpenCode automatically unless the user explicitly asks.
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.

setup is a command published in the GitHub repository skillsland/opencode-plugin-cc (1 stars, last pushed 3mo ago), licensed MIT. It adds 15 tokens to every session and 183 once invoked, about $0.0001 per session on Opus 5. 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.
