10-go-cobra-cli

A set of Go and Cobra rules for changing ROSA command-line commands and packages. Cobra is a Go library for building commands and flags.

In plain words
What is it for?
Use it when adding or changing ROSA commands, flags, command packages, or their structure-test files.
Why use it?
It keeps command behavior, errors, output, and structure tests consistent with the surrounding ROSA code.

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 260 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

10-go-cobra-cli 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 Go And Cobra

  • Prefer thin Cobra command files. Move non-Cobra logic into pkg/.
  • Follow the entrypoint and exit pattern already established in the nearest similar command area.
  • Many ROSA commands use Run: run; do not switch a command area between Run and RunE, or add/remove direct os.Exit() calls, unless the surrounding pattern already does so and the change keeps behavior consistent.
  • Follow machinepool commands and nearby code for patterns before creating new command shapes.
  • Keep error handling consistent with reporter usage, exit behavior, and surrounding package messages.
  • Update command structure contracts when commands or flags change:
    • cmd/rosa/structure_test/command_structure.yml
    • matching cmd/rosa/structure_test/command_args/**/command_args.yml
  • Do not change imports, run go mod tidy, or run go mod vendor unless the task explicitly requires it.
  • Use descriptive names and repo casing conventions such as ...Hcp.
  • Keep user-facing output consistent with pkg/output, pkg/reporter, and pkg/interactive.

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.
