00-rosa-baseline

Core working rules for contributors and coding agents in the ROSA repository. ROSA is a command-line tool, and these rules describe where code belongs, which files are generated, and which project guidance to follow.

In plain words
What is it for?
Use them as a baseline when changing the ROSA codebase, especially command wiring, package logic, tests, documentation, or release-related work.
Why use it?
They reduce inconsistent changes and prevent direct edits to generated or vendor files. They also remind contributors to keep command structure and repository tests aligned.

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

00-rosa-baseline 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

ROSA Baseline

  • Start with AGENTS.md. If there is a conflict, AGENTS.md and the exact file it references win.
  • Keep Cobra wiring in cmd/ and business logic in pkg/.
  • Do not edit generated files directly:
    • assets/bindata.go
    • pkg/*/mocks/
    • cmd/create/idp/mocks/
    • vendor/
  • Do not weaken tests to make a change pass.
  • Do not do release work from this repository.
  • Use CONTRIBUTING.md, the git hooks, Makefile targets, and the docs indexed from AGENTS.md for local workflow.
  • When commands or flags change, remember the structure-test files under cmd/rosa/structure_test/.
Changes

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.
