What it does
Cn Ib Memo Builder is an agent skill from QiushenZou/cn-investment-banking-skills. Turn source materials into concise, source-backed Chinese investment-banking memos with clear facts, analysis, decisions, risks, and actions. Use for project updates, diligence findings, issue memos, transaction-path analyses, internal briefing notes, meeting follow-ups, 上会材料摘要、事项备忘录、项目进展、风险事项、核查结论、交易方案 or management-ready summaries in Markdown or Word. Preserve the requested template and distinguish evidence from inference; do not use for investment recommendations.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `assets/memo-template.md` and `references/drafting-style.md`).
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.
When your agent uses it
- Project updates
- Diligence findings
- Transaction-path analyses
- Internal briefing notes
Example prompts
- “/cn-ib-memo-builder”
Requirements
- Python 3
Workflow steps
6 steps, taken from the step headings in SKILL.md.
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 1 file 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 Memo Builder loads about 1.1k tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 123 tokens; SKILL.md has 498 words of instructions outside code blocks.
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.

CN IB Memo Builder
Produce a memo that lets a senior banker understand the decision, evidence, risk, and next action quickly.
Principles
- Start with the decision or conclusion, not a chronology of work performed.
- Distinguish confirmed fact, source statement, analysis, assumption, and open question.
- Support material facts with stable source identifiers and precise locators.
- Keep unresolved issues visible with owner, deadline, dependency, and consequence.
- Preserve the user's template, defined terms, and requested sections.
- Never manufacture a conclusion when the evidence is incomplete.
Workflow
1. Define the memo's job
Read references/memo-types.md. Confirm:
- reader and decision required;
- memo type and required length;
- reporting cut-off and transaction stage;
- approved sources and confidentiality level;
- required template, headings, and sign-offs.
If no template is supplied, start from assets/memo-template.md and remove irrelevant sections rather than filling them with generic prose.
2. Build an evidence ledger
Before drafting, assign each material source a stable ID such as [S1]. Record:
source_id, title, date, file_or_url, page_or_cell, owner, statusExtract facts with original wording, period, unit, scope, and caveat. Use cn-ib-source-verifier for calculation lineage or cn-ib-cross-document-check when sources disagree.
3. Create the issue structure
For each material issue, state:
- Conclusion: what the evidence currently supports;
- Facts: source-backed observations only;
- Analysis: why the facts matter to the transaction;
- Gap or risk: what remains uncertain and the consequence;
- Action: next step, owner, deadline, and closure evidence.
Do not hide a qualification in a footnote when it changes the conclusion.
4. Draft conclusion-first
Read references/drafting-style.md. Write the executive summary after the issue analysis, then move it to the front. Use tables for decisions, open items, and comparisons; use prose for reasoning that needs context.
Keep source tags close to supported statements:
公司截至2026年6月30日的在手订单为人民币10亿元。[S2]Label management representations, estimates, and adviser analyses explicitly.
Show full SKILL.md (213 more words)Show less
5. Validate the draft
Read references/source-and-review.md, then scan a Markdown draft:
python3 scripts/check_memo_markdown.py memo.md --output memo-issues.csvThe script detects unresolved placeholders, missing core headings, empty sections, uncited quantitative claims, unsupported superlatives, duplicate punctuation, and broken source tags. Adjust required headings with repeated --required-heading options when the user's template differs.
6. Reviewer-ready close
Verify:
- the executive summary agrees with the detailed sections;
- dates, units, names, and transaction terms are consistent;
- every material conclusion states its evidence and limitations;
- every open item has an owner and next step;
- source definitions resolve all citations;
- the final Word/PDF rendering has been visually inspected if delivered in that format.
When revising an existing Word memo, preserve the original and use native Word tracked changes by default. Keep edits granular, retain existing revisions and comments unless instructed otherwise, and do not simulate redlines with color or strikethrough. Use a transparent revision author such as Codex when none is specified. Verify the revision markup and render all changed pages; provide a clean accepted copy only when explicitly requested.
Output contract
Deliver:
- memo with conclusion-first executive summary;
- issue-by-issue fact, analysis, risk, and action;
- decision and open-item table;
- source register with exact locators;
- explicit assumptions, limitations, and unresolved disagreements.
Do not turn a management statement or professional inference into an unqualified fact.
