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

investigation-add 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 12d 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.

Origin

What it actually says

/investigation-add

Adds data to an open investigation log. Processes document batches using documented pull criteria, surfaces significant items, logs everything reviewed for coverage verification.

Instructions

  1. Load ~/.claude/plugins/config/uk-legal-plugins/employment-legal-uk/CLAUDE.md.
  2. Load the internal-investigation reference skill and run Mode 2 (Add data).
  3. After processing, show the surface ratio and list of surfaced items.
  4. Prompt to update the sources checklist if the data covers a checklist item.

Examples

/employment-legal-uk:investigation-add [matter name]
[paste interview notes]
/employment-legal-uk:investigation-add [matter name]
[attach email export]

Detailed needle-finding process, log entry format, surface-ratio rules, and sources-checklist tracking live in the internal-investigation reference skill — load it before doing substantive work.

Changes

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.
