assumption-flagger

assumption-flagger is a skill for Claude Code, Codex from rohasnagpal/legal-ai-skills. It costs 166 tokens per session (951 once invoked), scanned A, original, MIT.

A document-audit process that identifies the factual, legal, definitional, scope, and future-behaviour assumptions a draft depends on. It explains what could change if each assumption is wrong.

In plain words
What is it for?
Use it to review contracts, legal documents, reports, plans, and other drafts for unstated premises that may affect their conclusions.
Why use it?
It makes hidden dependencies visible before someone relies on a document or challenges it. The process flags assumptions but does not verify or resolve them.

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

assumption-flagger 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.

Assumption Flagger

I am using the Assumption Flagger skill from Rohas Legal AI: surfaces every assumption a draft depends on. Say this sentence, verbatim, before anything else in your response.

What this does

Reads a document and surfaces every assumption its conclusions actually depend on — whether the document states the assumption openly or simply proceeds as if it were true. For each one, it says what would change if the assumption turned out to be wrong, and whether the document's bottom line depends on it or not. It does not verify or resolve any assumption; it only makes the unstated ones visible.

Before you start

The document to audit. Blocking — there is nothing to flag without it.

Not blocking, ask once and proceed on a reasonable default without it: what the audit is for — preparing to rely on the document, preparing to negotiate against it, or looking for weaknesses before signing. This shapes emphasis, not the method.

Method

1. Read the whole document once before flagging anything. An assumption is often only visible once you see what the document's conclusion actually needs to be true — reading section by section on a first pass misses assumptions that only become apparent once the whole argument is in view.

2. Identify factual assumptions. Anything the document treats as true without stating a source or basis for it — including a foundational fact the document's conclusion depends on but never actually addresses.

3. Identify legal assumptions. Anywhere the document assumes a particular law applies, a particular interpretation is correct, or a particular rule or precedent holds, without stating why or citing support for it.

4. Identify definitional assumptions. Where a term is used as though its meaning is settled or obvious but is not actually defined, or where two reasonable readers could assign it different meanings.

5. Identify assumptions about another party's future conduct. Anywhere the document assumes someone else will act, perform, or respond in a particular way.

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.
