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 | $0.00000 | $0.00674 |
| Opus 5 | $0.00000 | $0.00337 |
| Sonnet 5 | $0.00000 | $0.00135 |
| Haiku 4.5 | $0.00000 | $0.00067 |
Grade A, and why
reality-test 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 4d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reality-Test Assumptions
Counter confirmation bias by actively seeking evidence that could prove you wrong. Test assumptions before committing.
Instructions
Identify key assumptions underlying your decision and design ways to test them with real data, not just analysis.
Output Format
Decision/Belief Being Tested: [What we're evaluating]
Identify Assumptions
What are you assuming to be true?
| Assumption | Confidence | Importance |
|---|---|---|
| [assumption 1] | High/Med/Low | High/Med/Low |
| [assumption 2] | High/Med/Low | High/Med/Low |
| [assumption 3] | High/Med/Low | High/Med/Low |
Consider the Opposite
For each key assumption, what would convince you it's wrong?
| Assumption | What Would Change My Mind |
|---|---|
| [assumption] | [disconfirming evidence] |
| [assumption] | [disconfirming evidence] |
Deliberately seek disconfirming evidence: Where can we look for evidence that we're wrong?

Base Rates
What's the general success rate in situations like this?
| Situation | Base Rate | Source |
|---|---|---|
| [similar situation] | [%] | [where we know this from] |
Are we assuming we're different from the average? [Yes/No] If yes, what specifically makes us different?
Ooch: Small Bets
Can we test this with a small experiment before fully committing?
| What to Test | The "Ooch" | What We'd Learn | Cost/Time |
|---|---|---|---|
| [assumption] | [small test] | [insight] | [cost] |
| [assumption] | [small test] | [insight] | [cost] |
Pilot possibility: [How to test at small scale first]
Ask the Experts
Who has direct experience with this?
| Expert/Source | What They'd Know | How to Reach Them |
|---|---|---|
| [who] | [their expertise] | [how to contact] |
What would a skeptic say?

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.

reality-test is a command published in the GitHub repository neurofoo/agent-skills (111 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 674 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 2026-08-30.
