# 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."
