What is ha-evening-brief?

A daily Home Assistant summary of the home’s security, devices, and energy state. Home Assistant is software that monitors and controls smart-home equipment.

Use it as a scheduled evening report or request it on demand to check house security, device status, unusual sensors, and energy information.

It gives the operator an end-of-day check for unlocked or open items, lights left on, device errors, and pending updates.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00038	$0.01084
Opus 5	$0.00019	$0.00542
Sonnet 5	$0.00008	$0.00217
Haiku 4.5	$0.00004	$0.00108

Security

Grade A, and why

ha-evening-brief 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 4d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HA Evening Brief

An end-of-day house check that confirms the house is secure before night. Designed to run as the evening-brief routine at 22:30.

When both claude-code-hermit and claude-code-homeassistant-hermit are installed and evening-brief is enabled, this skill subsumes /claude-code-hermit:brief --evening — operators should disable the core evening routine to avoid duplicate ~22:30 notifications. For hermits without HA, /claude-code-hermit:brief --evening remains the standalone path.

Steps

Time & context — Call GetDateTime for current time. Read .claude-code-hermit/OPERATOR.md for language preferences.
Live house snapshot — Call GetLiveContext. Extract and organize:
- Security: alarm state, lock states, open covers/blinds
- Devices: robovac status (completed / docked / running / error), lights still on
- Any devices unavailable or in error state
Anomalous sensors — From the live snapshot, identify currently unavailable, stuck, or unexpected-state sensors. Report only what is currently wrong — no baseline diff required.

3a. Pending updates: Run ${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha updates --digest and capture stdout. Branch on its content (the command always exits 0 — never branch on exit code):

Contains (skipped: — log a single line to SHELL.md ## Monitoring (updates fetch failed: <detail after "skipped:">) and omit the Updates: section entirely.
Contains (no updates pending) — omit the Updates: section entirely.
Otherwise — render the digest lines as the Updates: section, translating tier labels into the operator's language. No proposal-id lookup here (unlike the morning brief).

Energy snapshot — From the live context, pull current power draw and day's energy consumption if HA energy entities exist. Omit this section if no energy sensors are available.
Compose brief — Write a concise evening brief in the operator's language (from OPERATOR.md). Use the format below.

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-evening-brief is a skill published in the GitHub repository gtapps/claude-code-hermit (74 stars, last pushed today), licensed MIT. It adds 38 tokens to every session and 1,084 once invoked, about $0.0002 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.
