building-chronologies is a skill for Claude Code, Codex from LegalQuants/lq-skills. It costs 59 tokens per session (1,533 once invoked), scanned A, original, Apache-2.0.

A sourced timeline of events built from legal documents, emails, witness evidence, or disclosure materials. Each event is linked back to the document that supports it.

In plain words
What is it for?
Use it to prepare timelines for pleadings, legal advice, witness preparation, mediation, or trial, and to identify duplicate events, conflicts, and missing information.
Why use it?
It turns a large case file into an organised view of what happened and when, while showing where each fact came from.

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

building-chronologies 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.

When to Use

  • A lawyer needs a timeline from a bundle, disclosure set, correspondence folder, witness statement set, or case file.
  • The user asks "what happened when" or needs chronology support for pleadings, advice, witness prep, mediation, or trial.
  • The output must cite each event back to a source document.

Do not use this skill to fill gaps from memory. A chronology is only as reliable as its sources.

Audience and Work Shape

Audience: litigators, trainees, paralegals, and litigation-support teams building first-pass chronologies for lawyer review.

Work shape: bounded extraction with accretive judgment. The skill extracts dated events from sources, then applies judgment to de-duplicate, flag conflicts, and surface gaps. It does not decide what happened.

  • Legal support, not legal advice: a chronology is a working evidence map, not merits advice, submissions, or a final statement of facts.
  • Privilege/confidentiality: if source material appears privileged or work-product-sensitive, flag it as privilege_review and do not include it in an externally shareable chronology without lawyer approval.
  • Accountability: the responsible lawyer decides whether a disputed or low-confidence event can be used in pleadings, evidence, settlement material, or submissions.

Access Modes

This skill works in three modes:

  1. Live source mode - use browser, web search, MCP, API, or other configured access to retrieve public filings, dockets, emails, storage folders, or document repositories.
  2. User-supplied source mode - use uploaded or pasted documents, correspondence, pleadings, disclosure exports, witness materials, PDFs, images, or OCR text supplied by the user.
  3. No-source mode - design the chronology schema and source-request list, but do not create factual chronology entries.

If documents cannot be retrieved or supplied, do not infer events from model memory. Mark missing periods, missing sources, and source requests explicitly.

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.
