SG Car Park Availability

Overview

Use this skill to answer Singapore car park availability queries by location/area and lot type. It is for informational wayfinding support only, not guaranteed parking outcomes.

Read these references before running:

• references/intake.md
• references/output-template.md
• references/source-map.md
• references/qa-checklist.md
• references/safety-assumptions.md
• references/review-contacts.md
• references/safety-evals.md

Workflow

1. Confirm request and scope

Capture or infer:

• Scope: current snapshot or specified recent time
• Area/location: town, planning area, carpark ID, or nearby landmark
• Lot type: C (car), Y (motorcycle), or all available types
• Output mode: quick summary or structured brief

If missing, default to:

• latest available snapshot
• nearby/area summary based on provided location text
• lot type C
• quick summary

2. Safety and misuse triage

Record:

• Risk tier: LOW
• Regulated domain: No
• Sensitive-period mode: No

Blocking behavior:

• Return Refuse for harmful, deceptive, or abusive requests.
• Return Input Required if location/scope cannot be inferred.

3. Gather sources with trust tiers

Use this order:

1. Tier 1 (primary): official Singapore transport/open-data sources for carpark availability.
2. Tier 2: official notices for outages, delayed updates, or maintenance windows.
3. Tier 3: media/community reports only as weak support; never sole basis for lot counts.

Verification rules:

• For available lots and total lots, use official published dataset values.
• If sources conflict, prefer official API/dataset and state conflict.
• If data is stale, delayed, or unavailable, mark Low confidence and Verification pending.
• Only mark Data pending when supported by official signals (empty/latest snapshot unavailable, or official outage notice).

4. Produce carpark-availability output

Follow references/output-template.md. Include:

• Query scope and as-of time
• Snapshot timestamp and data freshness status
• Requested area/location results (carpark ID when available)
• Available lots, total lots, and occupancy estimate when possible
• Source links
• Confidence labels and caveats

Use absolute timestamps in Singapore time. Clearly separate facts (published lot values) from inference (freshness/availability interpretation).

5. Apply QA and safety checks

Before finalizing:

• Run references/qa-checklist.md
• Ensure each listed carpark row includes source traceability
• Do not provide harmful misuse guidance
• Add caveats when data is stale, delayed, or partial
• Lower confidence when freshness cannot be verified

6. Return final response

Return concise, actionable parking-availability output. If user asks for fast output, use short sections:

1. Scope and as-of time
2. Snapshot and freshness status
3. Nearby/area results
4. Caveats
5. Confidence and links

Quality Bar

• Uses official Singapore data sources first for lot-count claims.
• Every time-sensitive statement has absolute Singapore timestamp.
• Facts and inference are clearly separated.
• Confidence labels are present in major sections.
• No guaranteed-availability language.

Reusable prompts

• "Show latest car park availability near Orchard Road with confidence labels."
• "Check if carpark availability data is fresh and list top nearby options."
• "Give me a quick SG carpark availability summary for this area: Tampines."
