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

Litigation Chronology 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.

Litigation Chronology

Purpose

Produce a structured, sourced factual chronology of events relevant to a litigation or dispute matter. Every event in the chronology is tied to a specific source document or Bates reference. The skill separates undisputed facts from disputed ones, flags evidentiary gaps, and never resolves or adjudicates a factual conflict. It produces draft legal work product for attorney review — not legal advice and not a statement of what happened.

Use When

  • A user asks to "build a timeline," "create a chronology," or "put the facts in order" from a set of documents.
  • Counsel needs a fact-organized view of events across multiple documents, productions, or depositions.
  • Pre-trial preparation requires organizing the documentary record by event date.
  • A mediation brief, motion, or opening statement requires a supporting factual narrative grounded in the record.
  • A second attorney is joining the matter and needs a document-grounded orientation to the facts.
  • Discovery gaps or missing time periods need to be identified and flagged.

Required Inputs

  • One or more source documents (contracts, correspondence, emails, text messages, records, pleadings, deposition excerpts, discovery responses, or other materials). Do not build a chronology without source documents.
  • Identification of each source document: document name, Bates range or other identifier, and date of the document if known.
  • The matter name or a brief description of the dispute (to give the chronology appropriate context).
  • The client's role (plaintiff, defendant, etc.) so that significance assessments can be framed appropriately.
  • Privilege posture of the source documents. For each source document (or the set as a whole), confirm one of the following: (a) all documents are cleared for use in this chronology (e.g., produced non-privileged materials); (b) some or all documents may be privileged or of mixed privilege status; or (c) privilege status is unknown. If status is unknown or mixed, do not proceed without attorney confirmation — record [ATTORNEY TO CONFIRM: privilege status of source documents before distribution of this chronology] and flag the chronology as potentially sensitive.

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.
