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 | $0.00207 | $0.00862 |
| Opus 5.5 | $0.00083 | $0.00345 |
| Sonnet 5.5 | $0.00041 | $0.00172 |
| Haiku 4.5 | $0.00021 | $0.00086 |
Grade A, and why
kernel-ops 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 — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
kernel-ops — la superficie operativa del context-kernel a parole
Questa skill è il gemello a linguaggio naturale dei comandi /ck-*: stessa
funzione, stessi script, ma raggiungibile dicendo cosa vuoi invece di ricordare
la sintassi. Gli script vivono sotto ${CLAUDE_PLUGIN_ROOT}/hooks/ (con la via
plugin) oppure, per l'install manuale, nella cartella hooks/ del plugin —
risolvi il path una volta e riusalo.
Principio (non tradire la filosofia)
Il plugin non fa mai tuning silenzioso. Questa skill può leggere e
diagnosticare liberamente, ma tutto ciò che scrive stato va fatto solo su
richiesta esplicita dell'utente, annunciando cosa sta per cambiare:
apply-rates (relax-only), write-priors (add-only), charter clear,
savings reset-canary. Nel dubbio: mostra, non attuare.
Instradamento dell'intento
Capisci cosa chiede l'utente e lancia il comando corrispondente (poi sintetizza l'output, non incollare referti lunghi):
| L'utente vuole… | Comando |
|---|---|
| stato/colpo d'occhio (risparmio, canary, coda A/B, carta) | savings.py + ab_verify.py --status + charter.py get |
| salute dell'installazione (health-check) | doctor.py |
| report risparmio token | savings.py (--html [path] per la pagina) |
| acquietare il canary dopo indagine (esplicito) | savings.py --reset-canary |
| giudicare i campioni A/B | ab_verify.py (--status, --dry-run, --limit N) |
| recuperare un output parcheggiato | recall.py --search REGEX | recall.py <chiave> --grep/--lines |
| vedere/rinfrescare/azzerare la carta del task | charter.py get | refresh | clear |
| smoke test della compressione | smoke.py generate poi smoke.py check |
| rilevanza rivelata (T5), solo report | revealed.py --aggregate |
| attuare tassi/prior appresi (esplicito) | revealed.py --aggregate --apply-rates | --write-priors |
Tutti eseguibili con python3 <hooks>/<script>. Se l'utente preferisce la forma
digitata, gli stessi passi sono i comandi /ck-status, /ck-doctor,
/ck-savings, /ck-verify, /ck-recall, /ck-charter, /ck-smoke, /ck-tune.
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.

kernel-ops is a skill published in the GitHub repository Pinperepette/context-kernel (24 stars, last pushed 2mo ago), licensed MIT. It adds 207 tokens to every session and 862 once invoked, about $0.0008 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.
