Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00051 | $0.01024 |
| Opus 5 | $0.00026 | $0.00512 |
| Sonnet 5 | $0.00010 | $0.00205 |
| Haiku 4.5 | $0.00005 | $0.00102 |
Grade A, and why
ha-setup-house 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 3d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Set Up Your House
Guided build-out of your Home Assistant house structure. Each step runs existing ha-agent-lab commands — no new subsystem. Every write is gated by ha_safety_mode (strict = proposal, ask = --confirm prompt).
Steps
1. Take inventory
Run all four in parallel and present a summary:
${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha list-areas
${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha list-entities --registry
${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha list-devices
${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha list-helpers
Report:
- Number of areas, entities, devices, and helpers found
- Entities with no area assigned (unplaced)
- Devices with no area assigned (unplaced)
- Whether a context snapshot exists at
.claude-code-hermit/raw/snapshot-ha-normalized-latest.json
2. Create areas
Ask: "Which rooms or zones would you like to create? (e.g. Living Room, Kitchen, Bedroom 1)"
For each area the operator names:
- Check the
list-areasoutput — skip if the area already exists (case-insensitive match on name). - Run:
${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha create-area "<name>" [--confirm] - Handle the result:
"ok": true— created; confirm to operator."requires_confirm": true—ha_safety_modeisask; prompt operator, re-run with--confirmon approval."blocked": true—ha_safety_modeisstrict; explain and create a proposal via/claude-code-hermit:proposal-create.
After creating all areas, re-run ha list-areas and store the updated area map.
3. Assign unplaced entities
From the unplaced entity list (step 1), ask the operator which entities to assign and to which area.
For each assignment:
${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha set-entity-area <entity_id> --area <area_id> [--confirm]
Use the area_id from the list-areas output, not the display name.
Handle requires_confirm / blocked the same as step 2.
4. Assign unplaced devices
From the unplaced device list (step 1), follow the same pattern:
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.
- 3d ago First seen · 115 lines · 51 tokens per session scan A a74e9c62223c
ha-setup-house is a skill published in the GitHub repository gtapps/claude-code-hermit (74 stars, last pushed today), licensed MIT. It adds 51 tokens to every session and 1,024 once invoked, about $0.0003 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 2026-09-03.
