What is flag-speculative-statements?

A set of instructions for making an AI label statements as verified facts, rules of thumb, or guesses. These labels make uncertainty visible instead of presenting every claim with the same confidence.

Use it when reviewing research, financial claims, technical advice, or any answer where separating known facts from assumptions and speculation matters.

It reduces the risk of treating estimates and predictions as confirmed information.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00023	$0.00935
Opus 5.5	$0.00009	$0.00374

Security

Grade A, and why

flag-speculative-statements 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 2mo 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.

Ask AI to Flag Speculative Statements (Epistemic Tagging) (AI Skill)

Overview

Because AI models are trained to write in a consistent, authoritative tone, they deliver a verified historical date ("The Apollo 11 moon landing was in 1969") and an unverified financial estimate ("Competitor X generates $45M in ARR") using the exact same confident cadence.

The Epistemic Tagging Protocol forces the AI to prepend explicit visual markers ([VERIFIED FACT], [HEURISTIC / ESTIMATE], [SPECULATION]) to its claims, making uncertainty instantly recognizable.

Master Epistemic Tagging Prompt Templates

Pattern 1: The Tagged Market & Intelligence Brief

Use for market research, competitor teardowns, and trend forecasting:

Analyze [COMPETITOR / MARKET TREND / TOPIC].

Formatting Directive:
Every paragraph or major bullet point MUST begin with one of these 3 epistemic tags:
- `[VERIFIED FACT]`: If supported by public SEC filings, official documentation, or verified press releases.
- `[HEURISTIC / ESTIMATE]`: If derived from industry benchmarks or standard sizing models.
- `[SPECULATION]`: If based on rumors, future projections, or AI deduction.

Do not smooth over uncertainties with confident language.

Pattern 2: The "Admit Unknowns" Guardrail

Use for scientific, technical, or regulatory inquiries:

flag-speculative-statements is a skill published in the GitHub repository alivirgo/Major-AI-Skills (2 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 935 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-05.
