fabricated answer · false claim

Hallucination

Generated information presented as factual when it is false or inconsistent with supplied material.

Everyday phrases

  • verify a doubtful answer
  • my agent invents sources

Key difference

A confident answer or citation is not evidence; open the source and check the passage supporting each useful claim.

Example

An answer attributes a date to a contract that contains no such date; you mark the claim unverified and reread the contract.

Counter-example

A story explicitly requested and presented as fictional is not a factual claim to verify.

Implement correctly

Use Hallucination deliberately

# Ground Hallucination in your agent

## Objective
Use “Hallucination” precisely in code, documentation, and conversations: Generated information presented as factual when it is false or inconsistent with supplied material.

## Prerequisites
- Inspect how the term is used today in the repository, documentation, and prompts.
- Identify the neighboring notions already named: Agent, Chatbot.
- Preserve existing correct usages.

## Working definition
Generated information presented as factual when it is false or inconsistent with supplied material.

## Decisive difference
A confident answer or citation is not evidence; open the source and check the passage supporting each useful claim.

## Example that counts as Hallucination
An answer attributes a date to a contract that contains no such date; you mark the claim unverified and reread the contract.

## Counter-example
A story explicitly requested and presented as fictional is not a factual claim to verify.

## Acceptance criteria
- Every use of the term matches the working definition.
- Edge cases are settled with the decisive difference, not by intuition.
- Neighboring notions (Agent, Chatbot) are named with their own term.

## Guardrails
- Show the proposed changes before any external action.
- Do not publish, send, delete, pay for, or change remote state without explicit authorization.
- Preserve unrelated changes and stop if the scope becomes ambiguous.

## Output format
- Outcome or verdict.
- Files or actions involved.
- Checks run and observable evidence.
- Remaining blockers or limitations.
  • Requires · The agentic vocabulary already used in the repository and documentation
Why it works
  • The notion is framed by a sourced working definition, not ambient usage.
  • The decisive difference settles edge cases reproducibly.
  • The example and counter-example bound the term on both sides.

Map the neighboring notions

# Map the neighboring notions

## Objective
Extend the same rigor to the related notions (Agent, Chatbot) so the project vocabulary stays coherent.

## Checks
- List every neighboring notion used without a definition.
- Apply its documented decisive difference.
- Record the still-ambiguous cases for the next entry.

## Guardrails
- Show the proposed changes before any external action.
- Do not publish, send, delete, pay for, or change remote state without explicit authorization.
- Preserve unrelated changes and stop if the scope becomes ambiguous.

## Output format
- Outcome or verdict.
- Files or actions involved.
- Checks run and observable evidence.
- Remaining blockers or limitations.

Diagnose a problem

Fix a Hallucination mix-up

# Fix a mix-up around Hallucination

## Observed symptom
[DESCRIBE THE SYMPTOM HERE]

## Observable checks
- Compare the disputed usage with the working definition: Generated information presented as factual when it is false or inconsistent with supplied material.
- Apply the decisive difference: A confident answer or citation is not evidence; open the source and check the passage supporting each useful claim.
- Confront the case with the documented counter-example: A story explicitly requested and presented as fictional is not a factual claim to verify.

## Possible causes
- The term is used for a neighboring notion (Agent, Chatbot).
- The observed form (interface, script, service) is confused with the actual behavior.
- An alias (fabricated answer, false claim) carries a different meaning in the project.

## Bounded fixes
- Rename or reclassify only the usages that contradict the working definition.
- Document each choice by citing the decisive difference.

## Final verification
- Reread every corrected occurrence against the documented example and counter-example.

## Guardrails
- Show the proposed changes before any external action.
- Do not publish, send, delete, pay for, or change remote state without explicit authorization.
- Preserve unrelated changes and stop if the scope becomes ambiguous.

## Output format
- Outcome or verdict.
- Files or actions involved.
- Checks run and observable evidence.
- Remaining blockers or limitations.
  • Requires · The agentic vocabulary already used in the repository and documentation
Why it works
  • The diagnosis compares usage with documented criteria instead of an opinion.
  • Fixes stay bounded to genuinely contradictory usages.
  • The final verification runs back through the sourced example and counter-example.

## Objective

## Checks
- Add the working definition to the project glossary.
- Link every neighboring term to its own entry.
- Check new documents against the decisive difference.

## Guardrails
- Show the proposed changes before any external action.
- Do not publish, send, delete, pay for, or change remote state without explicit authorization.
- Preserve unrelated changes and stop if the scope becomes ambiguous.
