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.

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 | $0.00211 | $0.02286 |
| Opus 5 | $0.00105 | $0.01143 |
| Sonnet 5 | $0.00042 | $0.00457 |
| Haiku 4.5 | $0.00021 | $0.00229 |
Grade A, and why
ha-panel-add 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
HA Panel Add
Spec: spec/claude/ha-panel-add/en.md (EN canonical) / spec/claude/ha-panel-add/de.md (DE translation).
Why this is a skill, not an agent
- Human-visible augmentation surface — the user describes a full-page sidebar page and reads back the panel element, the
panel_customregistration, and the conformance report; a skill keeps this on the visible command surface, like the sibling frontend skillha-lovelace-card-scaffold. - Mid-flow interactivity — the delivery-shape decision (custom panel vs. custom view vs. panel-mode view) is a per-run dialogue the user approves before generation.
- Bounded, inline generation — one panel element plus its ES-module wiring and the
panel_customconfig fit inline; no isolated agent context is needed. - Counter-dimension considered: the draft→validate loop could be an agent, but the delivery-shape advice and the
url_path/registration decisions belong in the user's working context; skill wins.
When this skill activates
Use this skill to add one custom panel — a full-page custom element registered in the sidebar that takes over the whole content area — to an existing integration or frontend repo, when the need is a genuine full-page page (not a layout inside a dashboard).
When NOT to activate
- a single card →
ha-lovelace-card-scaffold/ha/lovelace-card-patterns - a panel-mode view (a
type: panelview holding one full-width card — dashboard YAML, not a scaffolded card) →ha-panel-author(owns the delivery-shape decision incl. panel-mode view) perha/lovelace-views-panels - a custom view as a layout container (renders core cards/badges via
ll-*events) →ha/lovelace-views-panels(view part), not this skill - a programmatic dashboard strategy →
ha/lovelace-strategies - a WebSocket command the panel calls →
ha/frontend-websocket-commands - greenfield integration scaffolding →
ha-integration-scaffold - deploying/importing into a running HA instance → out of scope
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.

ha-panel-add is a skill published in the GitHub repository nolte/claude-home-assistant (1 stars, last pushed 1mo ago), licensed MIT. It adds 211 tokens to every session and 2,286 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
