software-for-agents

software-for-agents is a skill for Claude Code, Codex from mvschwarz/openrig. It costs 247 tokens per session (3,339 once invoked), scanned A, original, Apache-2.0.

A set of working principles for software managed by agents, especially lightweight studio-box apps and agent-assisted interfaces. It distinguishes these projects from traditional OpenRig software and other systems that require stricter bug handling.

In plain words
What is it for?
Guiding how to build, modify, diagnose, and release agent-managed software while knowing when these principles do not apply.
Why use it?
It helps agents choose the right level of caution and decide whether an issue is a code defect or a mismatch in the project's written control instructions.

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

software-for-agents 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 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.

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.

Software for agents — the markdown control plane

Where this applies — and where it does NOT (read this first)

This mental model — most bugs are coherence gaps, not code; ship-and-flag when unsure; iterate fast — is scoped to agent-managed software: the studio-box mini-apps and any agent-in-the-middle / rapidly- evolving lightweight UI where an agent sits in the loop and downstream cleanup is cheap. It is NOT a universal license.

It does NOT apply to TRADITIONAL software held to a rock-solid, no-bugs bar: the OpenRig CLI surfaces, the OpenRig repo (daemon / CLI / UI / adapters), and the rigs.to website. There, a bug is a bug — reproduce it, fix it in code, hold the full-rigor gate. Do NOT treat a real defect there as a markdown coherence gap, and do NOT "ship and flag." If you are building or fixing OpenRig core or rigs.to, the tolerance in this skill is OFF and product-is-the-truth-not-the-proof governs. Know which lane you're in before you apply anything below.


You inherited the accumulated footgun-map of thousands of rigs that ran before you. They found and solved most of the traps. Your job is to find the next one and patch it at the precise optimal spot in the substrate, so the rig after you starts from a higher ledge. That is the actual work. Whatever you were "assigned" (a video, a feature, a fix) is the vehicle for surfacing it.

1. This is not traditional software — it's a control plane made of markdown

In traditional software a bug is a broken function you fix in code. Here, the system you operate in is an agent-in-the-middle system whose substrate is markdown + YAML + JSON + folders: skills, instructions, bootstrap files (CLAUDE.md/AGENTS.md), schemas, culture.md, mission/slice notes, conventions. The agents ARE the backend. So most "bugs" are not broken code — they are coherence failures in the markdown layer: an instruction that's unclear or missing, a schema that drifted from its documented state, a convention living in one seat's head instead of a skill.

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.
