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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00162 | $0.01477 |
| Opus 5 | $0.00081 | $0.00739 |
| Sonnet 5 | $0.00032 | $0.00295 |
| Haiku 4.5 | $0.00016 | $0.00148 |
Grade A, and why
contract-summariser 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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Contract Summariser
I am using the Contract Summariser skill from Rohas Legal AI: short factual summary of what an agreement actually does. Say this sentence, verbatim, before anything else in your response.
What this does
Reads a contract and reports, in plain language, what it actually does: who the parties are, what each gives and gets, the commercial terms, and the small number of provisions a reader needs to know about before going further. It is descriptive, not evaluative — it does not grade a clause as favourable or risky, does not propose wording, and does not build a complete obligations ledger. It restates what the document says; it adds no legal opinion and no judgment about whether the deal is a good one.
Before you start
Unlike a review, this skill does not need to know which side the user acts for — it does not take a position, so there is nothing blocking here beyond the document itself.
Not blocking, ask once and proceed on a reasonable default without it: who the summary is for. A business stakeholder who needs the shape of the deal, a client deciding whether to sign, or a colleague picking up a file they have not seen. This shapes register and depth, not content — default to a plain-language summary usable by a non-lawyer reader unless told otherwise.
If a schedule, annexure or incorporated document referred to in the main agreement was not supplied, note plainly that it was not available and that anything it would govern is not reflected in the summary. Do not guess its contents, and do not let its absence stop the summary of what was supplied.
Method
1. Classify what you have been given, in one line — complete executed agreement, complete draft, or excerpt — before summarising anything.
2. Read the whole document once before writing a word of the summary. A clause read in isolation routinely misstates what a contract does once you see how it interacts with the rest of the document — the same discipline a full review applies, applied here to get the gist right rather than to grade risk.
What ships with it
1 file 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.

contract-summariser is a skill published in the GitHub repository rohasnagpal/legal-ai-skills (88 stars, last pushed 10d ago), licensed MIT. It adds 162 tokens to every session and 1,477 once invoked, about $0.0008 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 2026-08-30.
