instana-agent-operator AGENTS.md

instana-agent-operator AGENTS.md is an instructions file for Codex, OpenCode from instana/instana-agent-operator. It costs 1,381 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for Instana Agent Operator, a Kubernetes operator written in Go. Kubernetes operators automate the management of applications and infrastructure in a Kubernetes cluster.

In plain words
What is it for?
Use them to build and test the operator, run linters and formatters, run end-to-end tests, validate Renovate configuration, and check for exposed secrets before committing.
Why use it?
They collect the project's required build, test, formatting, linting, Go version, commit, and secret-checking rules in one place. This reduces mistakes when working on the repository.

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

instana-agent-operator AGENTS.md 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.

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

Build & Test Commands

  • Build: make build
  • Lint: make lint
  • Format: make fmt or format specific file: ./bin/golangci-lint fmt ./path/to/file
  • Run tests: make test (excludes mocks and e2e directories)
  • Run single test: go test -v ./path/to/package -run TestName
  • E2E tests: make e2e (requires e2e/.env file - copy from e2e/.env.example)
  • Install golangci-lint if missing: make golangci-lint
  • Validate renovate.json: npx --yes --package renovate -- renovate-config-validator
  • Secrets baseline: detect-secrets scan --update .secrets.baseline before committing
  • Secrets audit: detect-secrets audit .secrets.baseline

Code Style

  • Go version: Check go.mod toolchain directive (currently go 1.25.0)
  • Line length: 120 characters max (enforced by lll linter)
  • Linters: See .golangci.yml for full configuration (govet, ineffassign, unused, misspell, exhaustive, errcheck, lll)
  • Commit messages: MUST include DCO sign-off with git commit -s. Use conventional commits syntax for subject, concise message with brief summary in body

Project-Specific Rules (Non-Obvious Only)

  • Error wrapping: MUST use github.com/pkg/errors package (not standard library errors)
  • Tools directory: All binaries install to ./bin/ (GOBIN override in Makefile)
  • Branch naming: Avoid / in branch names (breaks SPS/Tekton CI pipeline task names)
  • Container builds: Uses buildctl with containerized buildkitd (not direct docker build)
  • PR template: Fill out .github/pull_request_template.md and use as PR body

Kubernetes Operator Specifics

  • Finalizers: Two versions exist (finalizerV1 and finalizerV3) in controllers, prefer finalizerV3
  • ETCD discovery: Automatic on OpenShift - copies certs from openshift-etcd namespace to instana-agent
  • Namespace handling: Default namespace is instana-agent, not default
  • CRD versions: InstanaAgent has both v1 and v1beta1, RemoteAgent only v1
  • OpenShift detection: Uses oc command availability to detect OCP vs vanilla K8s
  • Local dev: make dev-run-cluster for full setup, make run to run operator locally
  • Cleanup: make purge removes all cluster resources including finalizers

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.
