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

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 yesterday.

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
  1. Create directory: kubernetes/apps/<namespace>/<app>/
  2. Add files: kustomization.yaml, app/helmrelease.yaml, optional externalsecret.yaml
  3. Configure placeholders: ${SECRET_DOMAIN}, ${DB_URI}, etc.
  4. Render: task configure
  5. Validate: task kubernetes:kubeconform
  6. Check diff: flux diff kustomization <namespace>
  7. Create PR, merge, monitor: flux get helmrelease <name>
Updating Configuration
  1. Edit templates in bootstrap/ or app manifests
  2. Render: task configure
  3. Validate: task kubernetes:kubeconform
  4. Review git diff
  5. 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.
