Singapore Skills

A curated collection of AI skills for Singapore-focused work.

This repository is building practical, reusable skills for local contexts across public policy, open data, transport, business, citizen services, and more.

Why this repo exists

Most generic AI prompts miss Singapore-specific context and source reliability needs. These skills encode repeatable workflows so outputs are:

• locally relevant
• source-backed
• concise and usable
• easy to share across tools

Skills in this collection

All public skills live under skills/public/.

Examples currently included:

• sg-skill-creator
• sg-weather-now
• sg-hdb-bto-announcements
• sgcarmart

As new Singapore-context skills are added, they are part of this same collection.

To quickly list current source skills:

find skills/public -mindepth 2 -maxdepth 2 -type f -name "SKILL.md" | sed 's|/SKILL.md||' | sort

Contribution Flow (Source-Only)

Contributors should create or update only source skill files under skills/public/<skill-name>/.

Required files:

• SKILL.md
• agents/openai.yaml
• references/*

Optional frontmatter (recommended for clearer website credits):

• author_name
• author_github

Do not manually maintain ports/claude, ports/gemini, or ports/universal files in PRs. Those are generated from source.

Full contributor guide: CONTRIBUTING.md.

Automation Flow

This repo auto-handles portability ports:

1. Pull request touching skills/public/**

• Workflow ports-sync.yml runs validation and regenerates ports in CI.

2. Merge/push to main

• Same workflow regenerates ports and auto-commits changes under ports/ when needed.

3. Website sync (separate repo)

• SGSkills-Website syncs this repo into vendor/SGSkills and updates website metadata.
• This is configured in SGSkills-Website/.github/workflows/sync-sgskills.yml.

Example prompts

• Use $sg-weather-now and summarize Singapore weather now, next 2 hours, and next 24 hours with confidence labels and official source links.
• Use $sg-skill-creator to create a new Singapore-first skill with trusted-source rules, confidence labels, and website-ready metadata.
• Use $sg-hdb-bto-announcements and explain the latest BTO process in simple steps with official source links.
• Use $sgcarmart to compare 5 Singapore used-car listings with value signals, risk flags, and negotiation points.

Cross-platform ports

See ports/README.md for using prompt ports in other tools.

Local install for other LLM tools

From repo root:

chmod +x ports/install.sh
./ports/install.sh claude ~/my-project all
./ports/install.sh gemini ~/my-project all
./ports/install.sh universal ~/Desktop all

Single-skill examples:

./ports/install.sh claude ~/my-project sg-weather-now
./ports/install.sh gemini ~/my-project sg-weather-now
./ports/install.sh universal ~/Desktop sg-weather-now

Convert any skill to other LLM formats

Regenerate Claude + Gemini + Universal adapters from source skills:

./ports/scripts/convert-skill.sh all
# or one skill
./ports/scripts/convert-skill.sh sg-hdb-bto-announcements
./ports/scripts/convert-skill.sh sgcarmart

Ports are generated from source skills. Contributors should update skills/public/<skill>/ only; CI auto-syncs ports on main.
