CNInfo Report Downloader（巨潮资讯报告下载）

批量下载A股上市公司年报/半年报 PDF（数据源：巨潮资讯 cninfo.com.cn）。

When to activate

• User wants to download A-share annual or semiannual reports
• User mentions 巨潮、cninfo、年报下载、半年报、annual report
• User needs to batch-fetch report PDFs from a stock-code list

Prerequisites

bash

pip install -r requirements.txt

Workflow

1. Confirm that a stock CSV exists and that its first column contains stock codes (6-digit A-share codes).
2. If unsure, run --dry-run first to preview matches without downloading.
3. Run the command from the skill directory. The script tracks progress in SQLite and can resume after interruption.
4. Check runtime/manifest_<year>.csv and runtime/logs/cninfo_<year>.log after the run.
5. Consult references/filter_rules.md only when adjusting title matching, naming, or reset behavior.

Commands

Normal download (default year 2025):

bash

python scripts/run_cninfo_reports.py --stock-csv <path-to-csv>

Dry-run (preview only, no download):

bash

python scripts/run_cninfo_reports.py --stock-csv <path-to-csv> --dry-run

Specify year:

bash

python scripts/run_cninfo_reports.py --stock-csv <path-to-csv> --year 2024

Force redownload (ignore cache):

bash

python scripts/run_cninfo_reports.py --stock-csv <path-to-csv> --force-redownload

Full CLI options:

Argument	Default	Description
--year	2025	Target report year

Features

• Smart title filtering — regex-based matching for formal annual/semiannual reports; auto-rejects summaries, English variants, ESG reports, notices, etc.
• Breakpoint resume — SQLite state tracks search progress and download status per announcement; resumes after interruption.
• Manifest output — runtime/manifest_<year>.csv with full metadata for every eligible report.
• Idempotent naming — {code}_{year}_{kind}.pdf for primary files, extra variants get _{announcement_id} suffix.
