Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00039 | $0.00466 |
| Opus 5 | $0.00019 | $0.00233 |
| Sonnet 5 | $0.00008 | $0.00093 |
| Haiku 4.5 | $0.00004 | $0.00047 |
Grade A, and why
ck-tune 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 2d 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
context-kernel — tune (rilevanza rivelata, T5 → T1)
Argomenti: $ARGUMENTS
Chiude il ciclo T5→T1: dai transcript reali misura cosa è stato davvero riletto (page fault ricorrenti) e, solo su comando esplicito, ne scrive i tassi/prior. Per contratto non c'è mai tuning silenzioso, e le attuazioni scattano solo su ricorrenza ≥ 2 sessioni/occorrenze, mai sul singolo episodio.
report(default) → aggrega la rilevanza rivelata senza scrivere nulla:python3 "${CLAUDE_PLUGIN_ROOT}/hooks/revealed.py" --aggregateapply-rates→ scrive i tassi per-estensione appresi dai fault ricorrenti. Relax-only: possono solo ALLEGGERIRE la compressione (relax/raw) per una categoria che è costata riletture, mai stringerla:python3 "${CLAUDE_PLUGIN_ROOT}/hooks/revealed.py" --aggregate --apply-rateswrite-priors→ scrive i prior di slice (seed additivi/flag freddi). Add-only: aggiungono seed o flaggano freddi, mai escludono:python3 "${CLAUDE_PLUGIN_ROOT}/hooks/revealed.py" --aggregate --write-priors
Modificatori: --last N (quanti transcript considerare), --json (output macchina).
Dopo un'attuazione, riporta cosa è stato scritto (la sezione ## attuazione esplicita).
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.

ck-tune is a command published in the GitHub repository Pinperepette/context-kernel (24 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 466 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 2026-08-30.
