# SG COE Bidding Results

## Overview

Use this skill to answer Singapore COE bidding result questions across Categories A-E.
It is for informational result-checking support only, not bidding strategy advice or guaranteed 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: latest exercise or specific exercise/date
- Categories: all (A-E) or requested subset
- Output mode: quick summary or structured brief

If missing, default to:
- latest published exercise
- all categories A-E
- 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 exercise/date scope cannot be inferred.

### 3. Gather sources with trust tiers

Use this order:
1. Tier 1 (primary): official OneMotoring/LTA COE bidding results pages.
2. Tier 2: official OneMotoring/LTA notices on schedule changes or publication delays.
3. Tier 3: media reposts only as supporting signals; never sole basis for category premiums/quotas.

Verification rules:
- For category premiums, quotas, and bids received, use official published results.
- If sources conflict, prefer OneMotoring/LTA and state conflict.
- If requested/latest exercise is not published yet, mark `Low confidence` and `Verification pending`.
- Only mark `Pending publication` when supported by official signals: page absence/placeholder after check, or an official schedule/announcement indicating future release.

### 4. Produce COE-results output

Follow `references/output-template.md`.
Include:
- Query scope and as-of time
- Exercise identifier/date when available
- Category table (A-E): quota premium, quota, bids received, and success-rate when possible
- Source links
- Confidence labels and caveats

Use absolute timestamps in Singapore time.
Clearly separate facts (published values) from inference (publication-status interpretation).

### 5. Apply QA and safety checks

Before finalizing:
- Run `references/qa-checklist.md`
- Ensure category rows include source traceability
- Do not provide bidding manipulation or guaranteed-win language
- Add caveats when data is pending or partially published
- Lower confidence when publication status cannot be verified

### 6. Return final response

Return concise, actionable results-checking output.
If user asks for fast output, use short sections:
1. Scope and as-of time
2. Exercise summary
3. Category results
4. Caveats
5. Confidence and links

## Quality Bar

- Uses official OneMotoring/LTA sources first for result claims.
- Every time-sensitive statement has absolute Singapore timestamp.
- Facts and inference are clearly separated.
- Confidence labels are present in major sections.
- No bidding-guarantee or manipulation language.

## Reusable prompts

- "Show the latest Singapore COE bidding results with category premiums, quota, bids received, and confidence labels."
- "Check whether the latest COE results are published yet and show verification status."
- "Give me Category A-E COE results for the latest exercise in a quick format."
