A-Share Source Health

Use this skill when the workflow depends on fresh A-share data and you need to know which source classes are usable right now before trusting the review.

Overview

This skill converts source uncertainty into a structured availability report. It does not replace market review; it decides which inputs are healthy enough to trust and which paths must be downgraded.

Hard Rules

1. Check source health before writing a high-confidence same-day conclusion when the environment looks unstable.
2. Separate available, degraded, and unavailable.
3. Do not hide partial failures. Mark them as data gaps.
4. If only slower or weaker sources remain, downgrade confidence in downstream conclusions.
5. Do not fabricate a successful source check from old results.

When To Use

• The user asks for 今天, 最新, 刚刚, or intraday A-share conclusions
• A prior step hits unstable pages, blocked requests, or inconsistent quote returns
• A picks workflow depends on tradability and needs fresh quote validation
• A portfolio review depends on same-day tape confirmation

Inputs & Preconditions

Minimum useful inputs:

• current review date
• intended workflow, such as market review, picks, or holdings triage
• any already observed source failures

Optional inputs:

• preferred quote source
• preferred browser or fetch path
• list of specific pages or APIs to verify

Workflow

Step 1: Anchor The Check

• State the current date and, when relevant, the intraday time
• State which downstream task depends on this source check

Step 2: Check Source Classes

Check these classes in order:

1. quote source
2. breadth or sector source
3. web page source
4. optional report source
5. optional image or screenshot parsing path

Step 3: Classify Each Path

Use one of:

• available
• degraded
• unavailable

Step 4: Assign The Fallback

For each unavailable or degraded source, define:

• fallback source class
• confidence downgrade
• missing fields that must be labeled as gaps
