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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.00857 |
| Opus 5 | $0.00030 | $0.00428 |
| Sonnet 5 | $0.00012 | $0.00171 |
| Haiku 4.5 | $0.00006 | $0.00086 |
Grade A, and why
juridical-reasoning-writing 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Juridical Reasoning and Writing
Primary source: Richard K. Neumann, Jr. and Kristen Konrad Tiscione, Legal Reasoning and Legal Writing, 7th ed.
Supporting source: Sentence and Paragraph Writing (author not identified in supplied text)
Generated: 2026-07-20 | Mode: study | Project role: method only
Core Frameworks
- Rule-based reasoning: decompose the governing rule into cumulative, alternative, exception, and remedy elements before applying facts.
- Rule proof / rule application: first establish what the law is and why the authority controls; then connect each legally significant fact to each element.
- Authority ladder: rank primary over secondary and mandatory over persuasive authority. Treat contrary authority as a problem to answer, never to hide.
- Statute / precedent split: statutory analysis starts with text, structure and authorized interpretive tools; precedent analysis synthesizes rules, then analogizes and distinguishes determinative facts.
- Proof paradigm: conclusion, governing rule, explanation/proof of the rule, application, counteranalysis, and conditioned conclusion. Vary depth with uncertainty and stakes.
- Persuasive theory: a theory must be legally sufficient, factually supported, strategically useful, ethically defensible, and simple enough to guide the document.
- Paragraph contract: one controlling idea per paragraph; topic sentence states the proposition, supporting sentences prove it, transition shows logical movement.
- Revision gates: revise separately for organization, authority, factual support, counterargument, sentence clarity, citation fidelity, and final polish.
Mandatory Use in This Project
- Brazilian primary law and official decisions control. These books teach method; they are not authority for Brazilian law.
- Every material assertion must map to
FATO -> PROVA -> NORMA -> APLICACAO -> CONSEQUENCIA -> PEDIDO. - Never convert a plausible inference into a fact. Label missing proof, temporal uncertainty, territorial uncertainty, and adverse authority.
- Produce a short answer early, but keep it conditional until all gates pass.
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

juridical-reasoning-writing is a skill published in the GitHub repository ehrodan/lexmcp (1 stars, last pushed 1mo ago), licensed MIT. It adds 60 tokens to every session and 857 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
