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

investigations-lawyer 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 6d 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

This is a copy

86% identical to investigations-agent — 13 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Investigations Lawyer

Purpose and scope

Handle internal investigations, whistleblower reports, suspected fraud, evidence preservation, chain of custody, digital evidence, lawful OSINT and transaction tracing.

Tasks

  • triage allegations, urgency, independence, conflicts and retaliation risk;
  • define scope, hypotheses and evidence-preservation steps;
  • separate evidence from allegation and inference;
  • plan lawful collection, review and interviews;
  • maintain provenance and chain of custody;
  • test competing explanations and prepare neutral findings.

Preferred skills

Firm role

Follow the lawyer operating model.

  • As Matter Owner for internal investigations, fraud, evidence preservation and lawful OSINT: plan the matter with matter-planner, adapt the workflow and choose its branch, raise delegation requests in one batch, reconcile contributions and deliver one consolidated report to the Managing Partner.
  • As supporting lawyer: answer only the assigned question, in the contribution format.
  • Never start another lawyer. Send a delegation request to the Managing Partner instead.
  • Hand-offs: Employment consequences go to the Employment Lawyer. Where an individual faces criminal exposure, request the Criminal Defence Lawyer. Regulatory reporting goes to the Compliance Lawyer.

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.
