ha-presence-report

ha-presence-report is a skill for Claude Code from gtapps/claude-code-hermit. It costs 63 tokens per session (1,026 once invoked), scanned A, a copy of ha-presence-report, MIT.

A Home Assistant report about who is home or away and how reliable the related person and device trackers are. It also summarizes recent arrivals, departures, and activity patterns.

In plain words
What is it for?
It helps investigate presence history, tracker reliability, and automations that depend on knowing who is home.
Why use it?
It makes stale or unavailable presence data visible before it causes problems in automations such as locks, alarms, or climate control.

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.

Security

Grade A, and why

ha-presence-report 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 1mo 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

HA Presence Report

Steps

  1. Call GetDateTime for the current time reference. Read the stored locale from .claude-code-hermit/OPERATOR.md under ## HA hermit (fall back to English if absent).

  2. Read .claude-code-hermit/raw/snapshot-ha-normalized-latest.json.

    • If the file is missing or older than 24 hours, prepend a staleness warning to the output:

      "Context snapshot is stale — run /claude-code-homeassistant-hermit:ha-refresh-context for accurate data."

    • Filter entity_index to keys starting with person. or device_tracker.. If no matching keys exist, emit "no presence entities found — presence tracking isn't configured in this HA instance" and stop. Do not proceed to the history fetch.
    • From the matched entities derive:
      • Current state: value of state field (home / away / unknown / unavailable) and last_changed → "since HH:MM" relative to now.
      • Reliability flags: mark an entity unreliable if state == "unavailable" OR last_changed is more than 48 hours ago (stale tracker).

  3. Run:

    ${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha fetch-history \
  --window-days 7 \
  --entities "device_tracker.*" "person.*" \
  --include-transitions

    This writes .claude-code-hermit/raw/snapshot-ha-history-7d-latest.json.

  4. Read snapshot-ha-history-7d-latest.json. For each presence entity:

    • Recent transitions: show the last 5 entries from transitions (ordered chronologically), formatted as HH:MM DD-Mon — <state>.
    • Home/away split: derive from state_durations — what percentage of the window was "home" vs "away".
    • Typical activity windows: bucket the transitions list by UTC hour, keyed on direction: transitions to home are arrivals, transitions to away are departures. Report the top 1–2 arrival hours and departure hours separately (e.g. "typically arrives around 18:00 UTC, leaves around 08:00 UTC"). With ≥7d of data and ≥5 total transitions, state the windows; below that threshold, say "insufficient data for pattern detection." (hour_histogram counts all events regardless of direction, so use it only as a fallback for entities whose states aren't home/away.)

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.
