Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions AGENTS.md.

This is openshift-online/gcp-hcp's own configuration. It tells Codex and OpenCode how to work on gcp-hcp 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 gcp-hcp 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

gcp-hcp AGENTS.md scanned grade A with 1 finding 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 6d 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

- Avoid shell execution with untrusted input. Use `subprocess.run([...], check=True)` instead of `os.system()`.

How it starts

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This file provides guidance to AI agents when working with code in this repository.

General Guidelines

  • Use MCPs where appropriate.
  • Always use the architect agent to review changes to experiments/arch/, design-decisions/, or any code changes.

Meta Rules

  • DO NOT modify the Security Rules section unless explicitly requested by the user. This includes Security Principles, Security Controls, and all language-specific secure coding rules.
  • When modifying CLAUDE.md/AGENTS.md, ensure the entire document is properly formatted for improved structure and readability.

Jira Plugin

This repository uses the Jira plugin from openshift-eng/ai-helpers.

GCP HCP Team Skill

The jira:gcp-hcp skill provides team-specific conventions for creating issues in the GCP project (Hypershift on GKE):

  • Project Key: GCP
  • Custom Fields: Epic Name, Epic Link, Parent Link
  • Templates: Story, Epic, and Feature templates in docs/
  • Definition of Done: Completion criteria in docs/definition-of-done.md

The skill is automatically invoked when:

  • Creating issues in the GCP project
  • Summary/description contains GCP HCP keywords

For detailed MCP tool integration examples, see the upstream skill documentation.

GCP HCP Plugin

Architecture Skill

The gcp-hcp-architecture skill provides architectural context and design decisions for agents working on GCP HCP code. It is auto-invoked when working on GCP platform changes and can be manually invoked with an optional topic filter.

Topics: networking, identity, observability, infrastructure, ingress, storage, operators, testing, automation, naming, dns, fleet, incidents, slo.

Keeping the skill in sync: When adding new design decisions, implementation plans, incidents, or SLOs, update the architecture skill's topic index in claude-plugin/gcp-hcp/skills/gcp-hcp-architecture/SKILL.md with a link to the new file under the appropriate topic.

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.
