PM Skills is a collection of plain-Markdown instructions that teach AI assistants structured methods for handling professional, personal, and life-admin tasks. People use it with Claude, ChatGPT, Gemini, Cursor, Codex, and other supported agents for work such as writing product requirements, reviewing documents, or planning difficult situations.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.00961 |
| Opus 5.5 | $0.00036 | $0.00384 |
| Sonnet 5.5 | $0.00018 | $0.00192 |
| Haiku 4.5 | $0.00009 | $0.00096 |
Grade A, and why
bookkeeping-categorization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Bookkeeping Categorization Skill
Messy books come from inconsistent categorization — the same expense landing in three different buckets. This skill sets up a sensible chart of accounts for the business and clear rules for where each kind of transaction goes (with the tricky cases called out), so the books stay clean, comparable month to month, and easy for an accountant to work from.
Note: this is an organizational aid, not tax or accounting advice. The correct treatment of specific expenses (deductibility, capitalization vs. expense, tax categories) depends on jurisdiction and your situation — confirm categories and tax handling with a qualified accountant. Never assert tax deductibility.
Working from a brief
Given "help me categorize my freelance business expenses", produce a usable chart of accounts and rules anyway — infer the relevant categories for that business type and give examples, marking anything tax-sensitive (confirm with your accountant). Never state what's tax-deductible as fact.
Required Inputs
Ask for these only if they aren't already provided (else infer and label):
- The business — type (freelance, agency, SaaS, retail…), size, and accounting basis (cash/accrual) if known.
- The tool — QuickBooks, Xero, a spreadsheet, etc. (so categories map to it).
- Typical transactions — the kinds of income and expenses that recur, and any that are confusing.
- Goal — clean monthly books, tax prep readiness, or clearer reporting.
Output Format
Bookkeeping Setup: [business]
1. Chart of accounts — a practical category list grouped by type:
- Income (sales/services, other income), COGS / direct costs, Operating expenses (the recurring categories for this business — software, contractors, marketing, rent, travel, etc.), Owner/Equity, and Other (taxes, fees).
| Category | Type | What goes here | Examples |
|---|
2. Categorization rules — clear "if it's X, it goes in Y" rules, including the edge cases that cause inconsistency:
- mixed personal/business, software vs. equipment, contractor vs. payroll, meals vs. entertainment, a refund, a transfer (not income), owner's draw (not an expense), etc. — each flagged (confirm tax treatment with your accountant) where relevant.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

bookkeeping-categorization is a skill published in the GitHub repository mohitagw15856/pm-claude-skills (1,449 stars, last pushed today), licensed MIT. It adds 91 tokens to every session and 961 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-12.
