realistic-prompt-generation

realistic-prompt-generation is a skill for Claude Code from elvisun/newsjack. It costs 55 tokens per session (1,425 once invoked), scanned A, original, MIT.

A prompt-writing tool that creates natural variations from an anonymized design brief. The brief describes user roles, tasks, constraints, stages, languages, and approved evidence without revealing target brands or products.

In plain words
What is it for?
Use it after designing a prompt structure and before checking prompts for contamination or meaning errors.
Why use it?
It helps produce realistic test prompts without accidentally steering them toward a particular company or inventing recommendations. It stops when the input contains restricted target information.

About the project

Newsjack.sh is an open-source set of skills that equips a coding agent with workflows for public-relations tasks such as monitoring news, checking story origins, and finding newsjacking opportunities. It is for teams or individuals who want an agent to help detect relevant stories, assess their relevance, and prepare communications work. The catalogue entries are Newsjack.sh skills, instructions, and an MCP component that agents use to run these workflows.

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

realistic-prompt-generation 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 24d 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.

Realistic Prompt Generation

Write authentic prompts without manufacturing recommendation opportunities.

This skill inherits the ethical floor from skills/ETHICS.md. It enforces anti-hallucination and evidence-bound language. Anti-spray and human-send are not applicable.

Hard context boundary

For unaided generation, accept only:

  • anonymized segment and role labels;
  • approved jobs, constraints, information acts, journey states, and locales;
  • short source-language fragments safe under the permitted-data rules;
  • evidence IDs and grades;
  • prompt_architecture.json;
  • style and turn-form requirements.

Do not accept or inspect:

  • target brands, products, domains, people, slogans, campaign terms, proprietary categories, or flattering claims;
  • current AI answers, rankings, mentions, citations, gaps, or target pages;
  • the contamination register itself.

If those fields appear, stop unaided generation and request a sanitized blind_design_brief.json. When subagents or fresh sessions are available, generate in a fresh context that receives only the blind brief and architecture.

The exception is an explicitly separate B0 aided pass. It may receive only the target aliases needed by approved B0 cells.

Preserve the canonical intent cell

For each architecture cell, hold constant:

  • underlying job;
  • journey state and information act;
  • material constraints;
  • persona/role and locale;
  • proximity band;
  • expected answer kind.

Create two core variants by default:

  1. the closest natural rendering of observed language;
  2. a natural paraphrase that preserves the same intent.

Use additional variants only for a wording-sensitivity pilot or rotating discovery. Do not create a full style × persona × locale grid.

Use variant_role: observed_language only when the candidate is verbatim or lightly normalized from a cited behavioral/query language sample. search_query_expanded, human_written, and llm_expanded candidates are natural_paraphrase or sensitivity; a source ID does not by itself make generated wording observed.
