legal-claim-economics

legal-claim-economics is a skill for Claude Code, Codex from LegalQuants/lq-skills. It costs 68 tokens per session (1,562 once invoked), scanned A, original, Apache-2.0.

A financial modelling guide for legal claims and litigation portfolios, including possible recoveries, fees, funding returns, insurance costs, and settlement distributions. It uses assumptions and scenarios rather than presenting one guaranteed outcome.

In plain words
What is it for?
It is for modelling damages, probability of success, fee arrangements, after-the-event insurance, adverse costs, funder returns, recovery waterfalls, sensitivities, and Monte Carlo scenarios.
Why use it?
It makes the financial consequences of different claim outcomes and funding arrangements easier to compare. The calculations support decisions but do not recommend whether to bring, settle, fund, or abandon a claim.

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

legal-claim-economics 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 13d 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, funder, or firm wants to model whether a claim or portfolio is economically viable.
  • The question involves damages, probability of success, fee arrangements, ATE, adverse costs, funder return, or recovery waterfall.
  • The user needs sensitivity or scenario analysis rather than a single best-case number.

This skill models economics. It does not recommend whether to bring, settle, fund, or abandon a claim.

Audience and Work Shape

Audience: litigation partners, litigation-finance counsel, funding analysts, and legally supervised team members with enough quantitative fluency to review assumptions and formulas.

Work shape: bounded transactional calculation in calculation_mode; accretive judgment in specification_mode. The skill models assumptions and scenarios, but the responsible lawyer or funder decides what action to take.

  • Legal support, not legal advice: outputs are working calculations and assumptions registers, not merits, enforceability, tax, regulatory, or professional-conduct advice.
  • Privilege/confidentiality: claim economics may be privileged or work-product material. Sharing with funders, auditors, counterparties, insurers, or third parties can affect privilege/confidentiality and needs lawyer approval.
  • Accountability: a lawyer or authorised investment decision-maker must sign off before any output is used for fund/no-fund, bring/no-bring, settle/no-settle, or client-facing advice.

Access Modes

This skill works in three modes:

  1. Calculation mode - use supplied assumptions and an available calculator, spreadsheet, code execution environment, or arithmetic worked in-session.
  2. User-supplied model mode - review an existing spreadsheet, calculator output, term sheet, budget, damages model, or funding proposal supplied by the user.
  3. Specification mode - build the model structure, assumptions list, and formulas, but do not invent calculated outputs.

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.
