What it does

Cn Ib Source Verifier is an agent skill from QiushenZou/cn-investment-banking-skills. Verify external sources, copied figures, dates, periods, units, calculations, and citation lineage behind Chinese investment-banking disclosures. Use when checking 招股书行业数据、政策、市场份额、排名、居民电价、补贴、CAGR、可比公司数据、年报数据、募投测算 or third-party citations for 来源准确性、数据更新、原文核验、计算复核 and evidence ledgers. Do not use secondary web summaries when a primary filing or official source is available.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `references/calculation-checks.md` and `references/source-connectors.md`).

It sits in Research & Science, covering Citation management. The repository describes itself as: Agent Skills for Chinese IPO sponsor execution: diligence, filing production, pre-submission QC, regulatory inquiries, and filing refresh. The licence is Apache-2.0.

  • Third-party citations for 来源准确性、数据更新、原文核验、计算复核 and evidence ledgers

Example prompts

  • “/cn-ib-source-verifier”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Build the claim ledger
  2. Classify the source
  3. Verify the locator and context
  4. Reperform transformations
  5. Run deterministic ledger checks
  6. Assess disclosure support

What it can do on your machine

Read from SKILL.md and the folder at commit b71a38c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cn Ib Source Verifier loads about 1.1k tokens when it runs, and up to ~3.7k if it reads all its reference files. Until then it costs about 99 tokens; SKILL.md has 431 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~99
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Verify external sources, copied figures, dates, periods, units, calculations, and citation lineage behind Chinese investment-banking disclosures. Use when checking 招股书行业数据、政策、市场份额、排名、居民电价、补贴、CAGR、可比公司数据、年报数据、募投测算 or third-party citations for 来源准确性、数据更新、原文核验、计算复核 and evidence ledgers.

CN IB Source Verifier

Audit the evidence chain from disclosed claim to primary source and, where applicable, reproducible calculation.

Principles

  1. Verify the claim actually made, not merely whether the source exists.
  2. Match source, date, geography, population, definition, period, currency, and unit.
  3. Separate direct copy, transformation, calculation, extrapolation, and management inference.
  4. Prefer primary and official sources. Use secondary sources only for discovery or clearly labeled context.
  5. Preserve the original value and text before normalization.
  6. Never update a volatile claim without stating the new as-of date and whether historical comparability changes.

Workflow

1. Build the claim ledger

Use assets/source-ledger-template.csv or equivalent XLSX fields:

text
claim_id, claim, section, claim_type, source_type, source_title,
source_locator, source_date, access_date, period, geography,
definition, original_value, reported_value, unit,
calculation_type, start_value, end_value, years,
review_status, reviewer, notes

Create separate rows when one sentence contains multiple independently verifiable claims.

2. Classify the source

Read references/source-hierarchy.md. Identify whether the source is:

  • regulator or government;
  • exchange or statutory filing;
  • issuer primary material;
  • recognized international organization or industry association;
  • licensed financial database;
  • professional research;
  • media or aggregator;
  • management representation;
  • unknown.

Do not describe an industry report as government data.

When selecting where and how to search, read references/source-connectors.md and use scripts/plan_source_search.py. Prefer a configured MCP when it is licensed and preserves lineage; otherwise use the official website, browser, or public web search. 见微数据 is a discovery/index layer unless the underlying exchange or CSRC filing is also verified.

3. Verify the locator and context

Open the primary source and confirm:

  • exact page, table, paragraph, URL, or dataset series;
  • publication and access date;
  • whether the source is final, revised, archived, or superseded;
  • geographic and product scope;
  • current/historical period;
  • numerator, denominator, and methodology;
  • currency, unit, nominal/real basis, tax basis, and seasonality where relevant.

4. Reperform transformations

Read references/calculation-checks.md. Reperform:

  • currency and scale conversion;
  • totals and percentages;
  • year-on-year changes;
  • percentage-point changes;
  • CAGR;
  • market shares;
  • per-unit and per-capita figures;
  • weighted averages.

Keep inputs in the evidence ledger. Do not hardcode an unexplained result.

5. Run deterministic ledger checks

For CSV ledgers, run:

bash
python3 scripts/check_source_ledger.py source-ledger.csv --output issues.csv

The script validates required lineage and reperforms direct-copy and CAGR checks. Review all contextual issues manually.

6. Assess disclosure support

Classify each claim:

  • verified_primary;
  • verified_calculation;
  • verified_secondary;
  • partially_supported;
  • stale_source;
  • definition_mismatch;
  • calculation_error;
  • source_not_found;
  • professional_judgment_required.

For rankings and superlatives, verify the comparison universe and date. A source that names selected companies does not prove an industry-wide ranking.

Output contract

Deliver:

  1. verified claim ledger;
  2. issues prioritized by filing impact;
  3. corrected calculation and formula where relevant;
  4. replacement primary source when available;
  5. stale or non-comparable claims;
  6. limitations and items requiring issuer, sponsor, counsel, or accountant confirmation.

Do not leave downloaded reports, screenshots, OCR files, or conversion artifacts in the user's project directory unless specifically requested as final evidence.
