name: prompting-pro description: Help formulate high-quality prompts for GPT-5.5, GPT-5.4, GPT-5.3-Codex, Gemini 3, and Nano Banana.

Prompting Pro

Purpose

Help formulate high-quality prompts for specific AI models based on official documentation and curated unofficial tips.

The skill can also operate in a lightweight maintenance mode: on request, it can re-check registered sources, look for newly published models or updated prompting guidance, and update the matching files in knowledge/, docs/, and tips/.

Usage

1. Identify the target or active model (e.g. gpt-5.5, gpt-5.4, gpt-5.3-codex, gemini-3, gemini-3*).
2. Read the relevant docs and tips for that model (official reference doc, community tips) from supported models. If model is missing inform user.
3. Check specialized overlays and add matching overlays for the task type.
4. Formulate the prompt with model-specific constraints, output format, and stop rules.

Overlay routing rule: if an overlay applies, combine model doc + model tips + overlay.

For maintenance or discovery requests, see knowledge/maintenance-requests.md.

Supported Models

Model	Reference Doc	Tips
GPT-5.5	docs/openai/gpt-5.5.md	tips/openai/gpt-5.5.md
GPT-5.4	docs/openai/gpt-5.4.md	tips/openai/gpt-5.4.md
GPT-5.3-Codex	docs/openai/gpt-5.3-codex.md	tips/openai/gpt-5.3-codex.md
Gemini 3	docs/google/gemini-3.md	-

Specialized Overlays

Use these as additional instruction layers for specific task classes.

Overlay	Applies to	Use when	Reference Doc	Tips
OpenAI Codex Overlay	gpt-5.5, gpt-5.4, gpt-5.4-mini, gpt-5.4-nano, gpt-5.3-codex	coding, debugging, verification-heavy tasks	Model-specific docs from Supported Models	tips/openai/codex.md
Nano Banana Image Overlay	gemini-3* (via Nano Banana image capability)	image generation or editing tasks	docs/google/nano-banana.md	tips/google/nano-banana.md

Mini variants

• gpt-5.4-mini and gpt-5.4-nano are considered operational variants of the GPT-5.4 family.
• They are not documented as standalone models in this repository.
• Use them for cost/latency-sensitive routing and keep prompt shape compatible with GPT-5.4 guidance.

General tips that apply across all models: tips/general.md
