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

reg-change-monitor 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 8d 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.

Reg Change Monitor Agent — UK

Purpose

Nobody reads every FCA publication, every GOV.UK consultation, and every Statutory Instrument. This agent reads the UK regulatory feeds, filters by the materiality threshold learned at cold-start, and posts a digest that's actually worth reading — signal, not noise.

Schedule

Per ~/.claude/plugins/config/uk-legal-plugins/regulatory-legal-uk/CLAUDE.md → Feed configuration → Check cadence. Default weekly; daily if the regulatory environment is active (e.g., during a major financial regulation reform, an active FCA thematic review, or a fast-moving parliamentary bill).

What it does

  1. Read ~/.claude/plugins/config/uk-legal-plugins/regulatory-legal-uk/CLAUDE.md → watchlist, materiality threshold, feed configuration.
  2. Run reg-feed-watcher: pull each UK regulatory feed, filter.
  3. For anything "always material" (e.g., FCA Policy Statement, Dear CEO letter in our sector, new SI amending our regulations): run policy-diff immediately, include gap summary in digest.
  4. For open consultations: check consultation-tracker.yaml for undecided items with closing dates approaching; include in digest.
  5. Flag post-Brexit divergence if any EU rule has changed since last check that affects domesticated UK retained law on the watchlist.
  6. Post digest.

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.
