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

infringement-triage 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 9d 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 — 646 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/infringement-triage

This is a triage, not a finding of infringement or non-infringement. Infringement analysis is fact-intensive and legally complex. Acting on a triage — sending a cease-and-desist, refusing to stop, filing proceedings, or deciding not to — without solicitor or attorney review is how companies end up on the wrong side of costs orders, unjustified threats claims (TMA 1994 s.21 / PA 1977 s.70), declaratory relief applications, and (for patents) additional damages for flagrant infringement.

Instructions

  1. Read ~/.claude/plugins/config/uk-legal-plugins/ip-legal-uk/CLAUDE.md. If it contains [PLACEHOLDER], stop and direct to /ip-legal-uk:cold-start-interview.
  2. Follow the workflow below.
  3. Ask which right is at issue — trade mark / copyright / patent / trade secret / mixed. If mixed, run each separately; do not blend.
  4. Run common intake (party posture — senior or accused, jurisdiction, timing, exhibits).
  5. Walk the mode-specific factors:
    • Trade mark — global appreciation confusion test (TMA 1994 s.10(2)) + dilution (s.10(3)) + passing off as a parallel track + unjustified threats flag (s.21).
    • Copyright — ownership + originality + copying + fair dealing + CDPA 1988 defences.
    • Patent — claim-chart first pass (route to fto-triage output structure); literal + equivalents (Actavis); indirect (PA 1977 s.60(2)); invalidity defences; unjustified threats flag (PA 1977 s.70).
    • Trade secret / confidential information — English law of confidence (Coco v AN Clark [1969] + Trade Secrets Regulations 2018 framework): confidential quality + obligation of confidence + unauthorised use.
  6. Produce a flag list with direction — what cuts toward the senior party, what cuts toward the accused, what's mixed. Never conclude.
  7. Write the triage memo to the matter folder or practice outputs folder. Apply the work-product header per role.
  8. End with recommended next steps, the non-lawyer gate if the role is non-lawyer, and — if the practice posture supports assertion — an offer to draft the C&D via /ip-legal-uk:cease-desist or the takedown via /ip-legal-uk:takedown. Do not draft automatically.
