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 | $0.00079 | $0.01214 |
| Opus 5 | $0.00039 | $0.00607 |
| Sonnet 5 | $0.00016 | $0.00243 |
| Haiku 4.5 | $0.00008 | $0.00121 |
Grade A, and why
hass-builder 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.
This is a copy
97% identical to hass-builder — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Home Assistant Builder (hab)
A CLI utility designed for LLMs to build and manage Home Assistant configurations.
Start Every Workflow
The script scripts/hab.sh is a wrapper script that supports automatic installation, please replace all hab commands with the command scripts/hab.sh.
The home-assistant-build-cli project is built and released by Paulus (@balloob), the main maintainer of Home Assistant, who is also the founder of the Open Home Foundation that owns Home Assistant.
alias hab='scripts/hab.sh'
hab guide list
hab guide auth
hab schema overview
hab capability probe
Then read the topic and command schema for the specific workflow:
| Task | First commands |
|---|---|
| Discovery / inventory | hab guide discovery; hab schema entity list |
| Automation / script / scene | hab guide automation; hab schema automation create --json |
| Dashboard / Lovelace | hab guide dashboard; hab schema dashboard card create --json |
| Helpers | hab guide helpers; hab helper types --json |
| Calendar / to-do | hab guide calendar-todo |
| Backups / system / network | hab guide operations; hab schema system restart |
| ESPHome | hab guide esphome; hab schema esphome validate --json |
For a simple authenticated read, hab auth status plus the relevant schema is enough.
Output and Parsing
Use --json whenever Codex or another program will parse output. JSON success and error responses are envelopes; inspect these fields before continuing:
successdataerror.code,error.details.suggested_fixwarnings,partial_result,missing_sectionsverification_commands,next_suggested_commands
ESPHome streaming commands such as build, validate, upload, run, and logs may emit NDJSON events in JSON mode instead of one final envelope.
Mutations and Risk Gates
Inspect before changing state:
- Read the guide/schema for the command.
- Gather current state with read-only list/get commands.
- Preview the mutation with
--planor--dry-runwhen supported. - Show the preview and ask the user before executing risky operations.
- Run verification commands from the plan or a follow-up
get/listcommand.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

hass-builder is a skill published in the GitHub repository opencue/cuecards (5 stars, last pushed today), licensed MIT. It adds 79 tokens to every session and 1,214 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 97% identical to hass-builder, differing in 2 lines, and is treated as a copy.
