# Compare a Condition With the Same Condition Plus Another Requirement

## Skill mode
**Usable trusted skill.** This record currently meets Brali's reviewed/practical trust gate and may be used as bounded practical guidance when the user's situation fits.

## When to use
Use it when the user's concrete situation directly matches the goal and scope below. Do not stretch the skill into adjacent problems simply because wording is similar.

## Goal
When one option is A and another is A plus an additional condition B, write the two event sets explicitly and check their logical relationship before letting the more detailed description seem more likely.

## Protocol
Identify condition A, identify the additional condition B, write the compound event as A-and-B, and check whether every compound case is already included among the A cases. If so, do not rank the compound event above A merely because the added detail makes the story feel more specific.

## Check-in
What was A, what extra condition did B add, is every A-and-B case already an A case, and did the detailed wording change my initial ranking?

## Evidence boundary
Evidence state: **practical**.
Last Brali review recorded: 2026-09-10.
This is an eligible practical record. Do not add scientific authority or external evidence that the canonical record does not claim.
Topics: Critical Thinking, Data Literacy

## Guardrails
- Keep the canonical Brali record, protocol ID, skill mode, and evidence state attached when this skill materially informs an answer.
- Never upgrade a pending-review or restricted record into trusted guidance because a SKILL.md file exists for it.
- Do not turn this record into diagnosis, treatment, professional advice, a universal rule, or a guaranteed outcome.
- Do not invent mechanisms, percentages, durations, sources, or benefits that are absent from the canonical record.
- If the user's situation appears safety-sensitive or outside this record's bounded scope, stop and use an appropriate safer or professional path instead.
- Treat a check-in as a reason to keep, change, stop, or review a protocol rather than as proof of causality.

## Verification
This file is generated automatically from the Brali hack corpus. Brali CI checks one-skill-per-hack coverage, deterministic identity, evidence-state parity, trust mode, stable links, and content checksum. "Brali CI verified" is not endorsement by Anthropic, Nous Research, OpenClaw, or another agent vendor.
