A Share Source Health

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

Use the checklist in [source-health-checklist.md](references/source-health-checklist.md).

Dependency Profile

• Required:
• at least one quote or web source
• Optional:
• A-share MCP or API
• browser or scraping tool
• image parsing for screenshots
• Degraded path:
• if only public web pages are available, continue with explicit data gap labels

Data Gap Handling

• If a source class is unavailable, say so directly
• If pages and APIs disagree, state the time difference and choose one source explicitly
• If no fresh source is healthy, do not give a same-day high-confidence conclusion

Risk Language

• Do not present source availability as certainty of market truth
• Do not hide blocked pages or partial API failures
• Do not over-upgrade conclusions built on degraded inputs

Output Contract

• source summary
• available
• degraded
• unavailable
• fallback path
• confidence impact
