What is home-ops copilot-instructions.md?

Repository instructions for running a homelab with GitOps, Kubernetes configuration, Helm releases, and Talos-managed machines. They point developers to the project documents and deployment workflow.

Use them when adding or updating homelab applications, secrets, Kubernetes manifests, or infrastructure workflows.

They reduce deployment mistakes by explaining where configuration belongs, how templates are rendered, and how changes are validated and applied.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01387	$0.01387
Opus 5.5	$0.00555	$0.00555
Sonnet 5.5	$0.00277	$0.00277
Haiku 4.5	$0.00139	$0.00139

Security

Grade A, and why

home-ops copilot-instructions.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 2mo 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.

Quick Reference

Core Pattern

This homelab uses GitOps + templated manifests:

Taskfile and Makejinja render templates from bootstrap/
Flux applies manifests from kubernetes/apps/<namespace>/<app>/
Talos manages immutable node configuration

Essential Workflows

Deploying New Apps

Create directory: kubernetes/apps/<namespace>/<app>/
Add files: kustomization.yaml, app/helmrelease.yaml, optional externalsecret.yaml
Configure placeholders: ${SECRET_DOMAIN}, ${DB_URI}, etc.
Render: task configure
Validate: task kubernetes:kubeconform
Check diff: flux diff kustomization <namespace>
Create PR, merge, monitor: flux get helmrelease <name>

Updating Configuration

Edit templates in bootstrap/ or app manifests
Render: task configure
Validate: task kubernetes:kubeconform
Review git diff
Create PR with flux diff evidence

Key Rules

Do:

✅ Always run task configure after editing templates
✅ Use placeholders for secrets (${SECRET_DOMAIN}, ${DB_URI})
✅ Define storage explicitly in HelmRelease persistence sections
✅ Pin container images: <tag>@<digest> (use crane digest)
✅ Follow conventional commits: chore(app): description
✅ Run task kubernetes:kubeconform before PRs
✅ Include flux diff output in PR descriptions

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.
