SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00221 | $0.02924 |
| Opus 5.5 | $0.00088 | $0.01170 |
| Sonnet 5.5 | $0.00044 | $0.00585 |
| Haiku 4.5 | $0.00022 | $0.00292 |
Grade A, and why
ha-grill 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 2mo 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 — 198 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Grill the developer before writing code
An agent that builds exactly what was asked builds the wrong thing surprisingly often. The request is the tip of a decision tree, and every branch left unasked gets guessed.
Here the guesses are expensive in a specific way: unique IDs, entity IDs, entry.data and the coordinator's data
shape reach users with the first release and are breaking to change afterwards
(ha-breaking-changes). A question costs a minute now; the same question answered
by a migration costs a release. Interrogate first — that is the whole point of this skill.
When to run it
| Situation | Grill? |
|---|---|
| Fresh blueprint, no real code yet | Yes — it produces the facts blueprint-scaffold demands |
| An existing integration about to be imported | Yes — before its baseline is taken; the install base decides how much of the import is affordable |
| First real feature after an import or migration | Yes — the imported code answers less than it looks like |
| A new platform, entity set, service action or flow step | Yes, once more than two or three decisions are open |
| A one-line request whose scope you cannot state back in one sentence | Yes |
| A bug with a known cause | No — debug it (ha-coordinator-debug) |
| A complete spec is already on the table | No. Say so, name the two or three real gaps, ask only those. |
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.

ha-grill is a skill published in the GitHub repository jpawlowski/hacs.integration_blueprint (54 stars, last pushed 5d ago), licensed MIT. It adds 221 tokens to every session and 2,924 once invoked, about $0.0009 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 2026-08-30.
