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 | $0.00033 | $0.00351 |
| Opus 5 | $0.00016 | $0.00176 |
| Sonnet 5 | $0.00007 | $0.00070 |
| Haiku 4.5 | $0.00003 | $0.00035 |
Grade A, and why
ck-charter 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 — charter (carta del task)
Argomenti: $ARGUMENTS
La carta è l'insieme dei vincoli che il fix deve rispettare, ognuno con citazione file:riga. Quando è salvata diventa attiva: una guardia PreToolUse inietta i vincoli rilevanti prima di ogni Edit/Write/Bash sui file citati, e sopravvive all'auto-compact.
get(default) → mostra la carta attiva:python3 "${CLAUDE_PLUGIN_ROOT}/hooks/charter.py" getrefresh→ ri-risolve deterministicamente ifile:rigadriftati contro l'anchor catturato al save. Match unico → aggiorna; zero o ambiguo → dichiarato irrisolvibile, mai indovinato:python3 "${CLAUDE_PLUGIN_ROOT}/hooks/charter.py" refreshclear→ azzera la carta (usalo quando il task è cambiato):python3 "${CLAUDE_PLUGIN_ROOT}/hooks/charter.py" clear
Se non c'è carta attiva, dillo in una riga e suggerisci che la carta si genera dalla pipeline kernel (skill kernel-invariants / kernel-pipeline).
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.
