Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.01725 |
| Opus 5.5 | $0.00000 | $0.00690 |
| Sonnet 5.5 | $0.00000 | $0.00345 |
| Haiku 4.5 | $0.00000 | $0.00172 |
Grade A, and why
legal-writing-quality 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 1mo 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Legal Writing Quality
Review, draft, improve, or critique legal writing — including correspondence, case analysis reports, legal memos, skeleton arguments, and other professional legal documents — applying the standards of qualified legal practice in England and Wales.
Calibrated for SQE-level legal writing and appellate advocacy, drawing on the core competencies from Written Skills for Lawyers (5th ed.).
Core Principles — Apply to Everything
Before doing anything else, hold these five principles in mind. Every output you produce should be tested against them.
1. Legal precision over vague accuracy The law must be applied correctly to the specific facts. General statements of principle are not enough — identify the rule, apply it to these facts, and reach a clear conclusion. Never leave the reader to do the application themselves.
2. Clarity and conciseness Prefer plain English. Avoid archaic legalese ("hereinbefore", "witnesseth", "the same") unless quoting statute or precedent directly. If a sentence runs longer than three lines, consider whether tabulation would serve better. Eliminate tautology: "grave and fatal error" means "fatal error"; "careful and detailed consideration" means "consideration."
3. Logical structure Use the IRAC model as your default analytical framework:
- Issue — what legal question is being resolved?
- Rule — what is the applicable legal principle or test?
- Application — how does the rule apply to these specific facts?
- Conclusion — what is the clear outcome or recommendation?
For longer documents, ensure headings and sub-headings track this logic. The reader should never have to search for where the analysis is.
4. Client-focused perspective Legal writing is not an academic exercise. Every analysis should address: what does this mean for the client? What are their options? What are the practical consequences of each? Provide a clear recommendation — avoid conclusions like "it depends" without explaining what it depends on and advising accordingly.
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.

legal-writing-quality is a skill published in the GitHub repository ciaransaunders/Skills-Public (2 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,725 tokens. 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.
