Fine to try.

By tamarillo-ai/theta (GitHub) · design · 15 stars · scanned at commit 08c084f

Apply when creating or editing prompts targeting GPT-5.5. Covers outcome-first prompting, reasoning-effort calibration, verbosity tuning, long-context handling, ambiguity management, tool persistence and validation, preamble and phase patterns, retrieval budgets, structured extraction, citation discipline, personality and collaboration style, coding autonomy, frontend prompting, and migration from GPT-5.4 or older GPT models.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'gpt-5-5-prompting' ] || [ -L ~/.agents/skills/'gpt-5-5-prompting' ]; then echo 'A skill folder named gpt-5-5-prompting already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/tamarillo-ai/theta' "$d" && git -C "$d" checkout --quiet '08c084f718b2b842cd53622ce0b1a1fb2888ccef' -- 'test/cast-fixtures/codex-cli/regression/just-works/.codex/skills/gpt-5-5-prompting' && mkdir -p ~/.agents/skills && cp -R "$d"/'test/cast-fixtures/codex-cli/regression/just-works/.codex/skills/gpt-5-5-prompting' ~/.agents/skills/'gpt-5-5-prompting' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'gpt-5-5-prompting' ~/.claude/skills/'gpt-5-5-prompting' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
