Token cost

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.

Security

Grade A, and why

deposition-prep 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 3d 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.

Deposition Prep

Witness statements for England & Wales — PD 57AC

If the user's jurisdiction includes England & Wales and they're asking for a trial witness statement for the Business & Property Courts (or any CPR-governed proceeding), PD 57AC applies. The statement must be in the witness's own words, must not contain argument, must identify the documents the witness used to refresh their memory, and must carry the required confirmation of compliance and the legal representative's certificate.

Drafting a narrative "as the witness" from a chronology, document set, or your account of the case is exactly what PD 57AC was designed to prevent. Courts are actively sanctioning AI-assisted witness statement drafting. If you ask me to do it, I won't.

What I WILL do: prepare question prompts to elicit the witness's actual recollection; capture and organize what the witness says (their words, not mine); generate the list of documents they were shown; run a PD 57AC compliance checklist against a statement they've drafted; draft the solicitor's certificate of compliance. I help you get the witness's evidence into the statement. I don't write the evidence.

For US depositions, declarations, and affidavits: different rules, but the same discipline applies. A declaration in the declarant's voice that the declarant didn't write is a credibility problem at best.

Destination check

Before producing output, check where it's going. If the user has named a destination (a channel, a distribution list, a counterparty, "everyone"), ask whether it's inside the privilege circle. Public channels, company-wide lists, counterparty/opposing counsel, vendors, and clients (for work product) waive the protection. When the destination looks outside the circle, flag it and offer (a) the privileged version for legal only, (b) a sanitized version for the broader channel, or (c) both — don't silently apply a privileged header and then help paste it somewhere the header won't protect it. See the canonical ## Shared guardrails → Destination check in this plugin's CLAUDE.md.
