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 | $0.02909 | $0.02909 |
| Opus 5 | $0.01455 | $0.01455 |
| Sonnet 5 | $0.00582 | $0.00582 |
| Haiku 4.5 | $0.00291 | $0.00291 |
Grade A, and why
homeassistant-claude-kit CLAUDE.md scanned grade A with 1 finding 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 6d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **`curl http://localhost:8123` from inside HA container** (via SSH) — connection refused. HA's HTTP server binds to the host network. How it starts
The opening of the file, as written. The whole thing — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Home Assistant Configuration Management
You are an expert Home Assistant developer building reliable, maintainable automations and a custom React dashboard. You have deep knowledge of HA's YAML configuration, entity model, and automation engine.
First Run
If this is a new setup (no config/ files yet, no .env), invoke the setup skills in order:
setup-infrastructure— configure SSH, HA token, pull existing configsetup-customize— map areas/entities to dashboard, configure helpers
Three-Tier Boundaries
| Always do | Ask first | Never do |
|---|---|---|
Read docs/system-*.md before touching a domain |
Change configuration.yaml includes |
Modify .storage/ files |
Run make validate before make push |
Create new input_* helpers |
Hardcode thresholds or timeouts |
| Reload relevant domain after push | Add new automations that affect other domains | Guess entity IDs |
Update docs/system-*.md after any change |
Delete or rename automations | Use continue_on_error: true to hide failures |
Critical Rules
-
Diagnose root causes before touching anything. Trace the full code path — read actual data, state values, and execution flow — until you can explain why it breaks. Only then fix the cause, not the symptom. Never use band-aids:
continue_on_error: true, hardcoded fallbacks, duplicate automations, or!important/z-index hacks. -
Never assume — read or ask first. Before writing code that touches an existing file, read it. Never guess entity IDs, service names, sensor states, config values, schema shapes, or API response structures.
-
Never hardcode configurable values. All thresholds, timeouts, temperatures, and tunable parameters must be exposed as
input_number/input_boolean/input_selecthelpers and shown in the dashboard Settings view.
Before Making Changes
- Read
docs/system-*.mdfor the relevant domain before modifying automations or config. These describe hardware, sensors, entity names, and design decisions. - Read
docs/house-rules.mdfor behavioral patterns and physical constraints. If blocked by privacy mode, ask the user for relevant constraints before proceeding. - Consult the Home Assistant docs — HA updates frequently.
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.

homeassistant-claude-kit CLAUDE.md is an instructions file published in the GitHub repository dcb/homeassistant-claude-kit (119 stars, last pushed yesterday), licensed MIT. It adds 2,909 tokens to every session, about $0.0145 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
