prompting

prompting is a skill for Claude Code from CarbeneAI/Forge. It costs 37 tokens per session (570 once invoked), scanned A, a copy of prompting, MIT.

A guide to writing clearer instructions for AI agents and managing the information they receive. It focuses on keeping useful context while removing unnecessary detail.

In plain words
What is it for?
Use it to structure prompts, define constraints, provide examples, and design agent instructions.
Why use it?
It helps agents follow requests more reliably when the available context is limited.

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

prompting 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 6d 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.

Core Philosophy

Context engineering = Curating optimal set of tokens during LLM inference

Primary Goal: Find smallest possible set of high-signal tokens that maximize desired outcomes

Key Principles

1. Context is Finite Resource

  • LLMs have limited "attention budget"
  • Performance degrades as context grows
  • Every token depletes capacity
  • Treat context as precious

2. Optimize Signal-to-Noise

  • Clear, direct language over verbose explanations
  • Remove redundant information
  • Focus on high-value tokens

3. Progressive Discovery

  • Use lightweight identifiers vs full data dumps
  • Load detailed info dynamically when needed
  • Just-in-time information loading

Markdown Structure Standards

Use clear semantic sections:

  • Background Information: Minimal essential context
  • Instructions: Imperative voice, specific, actionable
  • Examples: Show don't tell, concise, representative
  • Constraints: Boundaries, limitations, success criteria

Writing Style

Clarity Over Completeness

✅ Good: "Validate input before processing" ❌ Bad: "You should always make sure to validate..."

Be Direct

✅ Good: "Use calculate_tax tool with amount and jurisdiction" ❌ Bad: "You might want to consider using..."

Use Structured Lists

✅ Good: Bulleted constraints ❌ Bad: Paragraph of requirements

Context Management

Just-in-Time Loading

Don't load full data dumps - use references and load when needed

Structured Note-Taking

Persist important info outside context window

Sub-Agent Architecture

Delegate subtasks to specialized agents with minimal context

Best Practices Checklist

  • Uses Markdown headers for organization
  • Clear, direct, minimal language
  • No redundant information
  • Actionable instructions
  • Concrete examples
  • Clear constraints
  • Just-in-time loading when appropriate

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.

prompting is a skill published in the GitHub repository CarbeneAI/Forge (9 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 570 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to prompting, differing in 0 lines, and is treated as a copy.
