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 | $0.00027 | $0.00530 |
| Opus 5.5 | $0.00011 | $0.00212 |
| Sonnet 5.5 | $0.00005 | $0.00106 |
| Haiku 4.5 | $0.00003 | $0.00053 |
Grade A, and why
ha-refresh-context 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 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.
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.
What it actually says
HA Refresh Context
Steps
- Run
${CLAUDE_PLUGIN_ROOT}/bin/ha-agent-lab ha refresh-context. - Read the output JSON — note entity count and base_url_source.
- Read
.hermit/raw/snapshot-ha-normalized-latest.jsonto understand what's in the house. - Compare with the previous entity count (check your auto memory for a stored house profile).
- If new entities, areas, or domains appeared, update your auto memory with the house profile changes.
- If entities disappeared or became unavailable, note it in your auto memory.
Output
.hermit/raw/snapshot-ha-context-<date>.json+snapshot-ha-context-latest.json— raw HA API snapshot.hermit/raw/snapshot-ha-normalized-latest.json— processed entity/service index (fixed name).hermit/raw/audit-ha-context-refresh-<date>.md+audit-ha-context-refresh-latest.md— audit entry
House profile (first run or when profile changes): if new areas, domains, or significant entity changes are observed in step 5, write a durable house profile summary to .hermit/compiled/context-house-profile-<YYYY-MM-DD>.md with frontmatter type: context, title: "House Profile: <date>", created: <ISO8601>, task: <T-... for the open record in this turn; omit this field otherwise>, tags: [ha-context, house-profile, foundational], injection_stub: "House profile: <N> areas, <M> entities, <K> automations. Read compiled/context-house-profile-<date>.md for detail." (fill in the real counts). Inside an open record's turn, pipe [[compiled/context-house-profile-<date>]] into .hermit/bin/hermitd-run task note .hermit <id>. Otherwise skip the note.
When to Use
- Session start (via ha-boot) when context is stale
- Before building any automation
- After the operator reports changes to their HA setup
- Periodically to detect drift
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-refresh-context is a skill published in the GitHub repository gtapps/hermitd (79 stars, last pushed today), licensed MIT. It adds 27 tokens to every session and 530 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-02.
