synthorg: Command for Claude Code

.opencode/commands/harness-experiment.md

harness-experiment is a command for Claude Code, OpenCode from Aureliolo/synthorg. It costs 38 tokens per session (378 once invoked), scanned A, original, no licence file.

A command for running one recursion-depth harness test, verifying the treatment over the connection before spending resources, and recording the result in a round log.

In plain words
What is it for?
Use it to run and log a single harness experiment as the experimenter.
Why use it?
It structures each experiment and keeps its verification and outcome recorded.

Command for Claude CodeOpenCode

Written for OpenCode and Claude Code: installed under .opencode/, but also a Claude Code command (commands/*.md).

This is Aureliolo/synthorg's own configuration. It tells Claude Code and OpenCode how to work on synthorg itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything synthorg configures →

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

harness-experiment 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 3d 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
