Prompting Skill

prompting-skill

A portable skill for building reliable LLM prompts. Drop-in for [agentic-stack](https://github.com/codejunkie99/agentic-stack) or any harness that reads `SKILL.md` frontmatter.

Covers: structure, few-shot, anti-hallucination, output-format locking.

Install into an agentic-stack project

mkdir -p .agent/skills/prompting
cp SKILL.md .agent/skills/prompting/SKILL.md

Then register it by appending to `.agent/skills/_index.md`:

## prompting
Building reliable LLM prompts — structure, few-shot, anti-hallucination,
output-format locking.
Triggers: "write a prompt", "prompt engineering", "improve this prompt",
"system prompt", "few-shot", "prompt template"

And to `.agent/skills/_manifest.jsonl`:

What's inside

The skill distills five load-bearing rules, a production prompt structure, an anti-hallucination checklist, and a worked signature-verification example. See [`SKILL.md`](./SKILL.md).
