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
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00103 | $0.01267 |
| Opus 5 | $0.00051 | $0.00633 |
| Sonnet 5 | $0.00021 | $0.00253 |
| Haiku 4.5 | $0.00010 | $0.00127 |
Grade A, and why
college-cost 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
College Cost Skill
The two numbers that matter — the true all-in cost, and the monthly payment for the decade after — appear nowhere on the marketing or, tellingly, the financial-aid letter, which routinely blends grants (free) with loans (very much not) into one cheerful "award." This skill computes both numbers: net cost per year with aid honestly sorted, inflated forward (tuition outruns CPI), split into cash and borrowed, and the borrowed part converted into the graduate's first decade of monthly reality. Two offers become comparable the moment both are run through it.
What This Skill Produces
- The all-in number — net 4-year cost, cash vs. borrowed, from the script
- The offer decode — the award letter's lines sorted: grants/scholarships (free) vs. loans (repaid) vs. work-study (earned) — the blend untangled
- The monthly tail — the post-graduation payment, term, and total interest, stated next to a starting-salary reality check
- The comparison — two+ schools on identical assumptions, which the letters never are
Required Inputs
Ask for these if not provided:
- The sticker — full cost of attendance (tuition + room/board + fees, not tuition alone — the letter's fine print has it)
- The aid, sorted — the award letter's actual lines; anything ambiguous gets decoded ("award" ≠ grant until proven), and renewal conditions noted (GPA floors, year-one-only grants — the classic bait)
- The family math — what's payable in cash per year without borrowing; the gap is the loan share
- The candidate schools — for comparisons, each letter, same treatment
Programmatic Helper
python3 scripts/college_cost.py --sticker 32000 --aid 14000
python3 scripts/college_cost.py --sticker 32000 --aid 14000 --loan-share 60 --loan-apr 6.5 --json
Deterministic. Defaults: 4% cost inflation, 4 years, 50% loan share at 6.5% over 10 years — all overridable; the true-all-in line includes the loan interest the sticker never mentions.
Framework: The Honest-Number Rules
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.

college-cost is a cursor rule published in the GitHub repository mohitagw15856/pm-claude-skills (1,352 stars, last pushed 3d ago), licensed MIT. It adds 103 tokens to every session and 1,267 once invoked, about $0.0005 per session on Opus 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 2026-09-03.
