openrouter-free-opencode

An OpenCode connection to OpenRouter's free model router. The router chooses a free model dynamically, so the model served, speed, availability, and tool quality may vary.

In plain words
What is it for?
Trying inexpensive coding-agent runs, checking the actual model and provider used, recording tests and risks, and handing results to another agent.
Why use it?
It enables low-volume experiments without relying on one fixed free model, but its changing provider makes results less reproducible unless you inspect the receipt.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

openrouter-free-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 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.

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

OpenRouter Free Models Router through OpenCode

Use OpenRouter's free router for low-volume experiments. It selects a free model dynamically, so availability, latency, tool quality, and the served model can change. Inspect the provider receipt before treating the result as a reproducible review.

Final report:

  • SUMMARY: what you did
  • FILES_CHANGED: paths changed, or none
  • TESTS: commands and outcomes
  • RISKS: remaining uncertainty LEFT_BEHIND: none, or every resource intentionally left running

Required final fields: STATUS: DONE | PARTIAL | BLOCKED FOLLOW-UP: recommended next actions, or "none" HANDOFF: context the orchestrator must pass into the next call, or "none"

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.

openrouter-free-opencode is an agent published in the GitHub repository Nafjan/summon (4 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 181 tokens. 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.
