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 | $0.00049 | $0.01256 |
| Opus 5 | $0.00024 | $0.00628 |
| Sonnet 5 | $0.00010 | $0.00251 |
| Haiku 4.5 | $0.00005 | $0.00126 |
Grade A, and why
evaluating-trade-offs 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 11d 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 — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Evaluating Trade-offs
Help the user make clearer decisions between competing options using frameworks and mental models from 40 product leaders.
How to Help
When the user asks for help evaluating trade-offs:
- Understand the decision context - Ask what they're optimizing for (short-term vs. long-term, growth vs. quality, speed vs. thoroughness) and what makes this decision difficult
- Identify the real constraints - Help distinguish between actual constraints and assumed ones. Ask "What would you do if [constraint] weren't an issue?"
- Surface hidden costs - Help quantify the full cost of each option, including maintenance burden, opportunity cost, and second-order effects
- Apply the right framework - Use weighted criteria matrices for complex multi-factor decisions, or simple "would I start this today?" tests for continuation decisions
Core Principles
Optimize for order-of-magnitude, not precision
Alex Komoroske: "It doesn't really matter if it's 1,000 or 1,001, who cares? It's orders of magnitude larger than the alternative, and so it is better." Don't waste effort on false precision in uncertain environments - focus on whether one option is dramatically better, not marginally better.
Apply the "would I start this today?" test
Annie Duke: "If you wouldn't start this today, then that means that everything that you're putting into this going forward is the actual waste." When evaluating whether to continue a project, ignore sunk costs entirely. The only relevant question is whether you'd begin this effort with today's knowledge.
Think more, ship better
Anuj Rathi: "Most experiments should be thought experiments. They should not even be tried out because they're obviously going to fail." Don't default to "let's just try it" - rigorous upfront thinking eliminates weak ideas before they consume engineering resources.
Accept "worse first" for long-term gains
Graham Weaver: "Everything you want is on the other side of worse first." Meaningful change requires accepting short-term decline. Ask what your 5-year future self would want, not what makes tomorrow easier.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

evaluating-trade-offs is a skill published in the GitHub repository cnfeat/top-pm-skills (48 stars, last pushed 3mo ago), licensed MIT. It adds 49 tokens to every session and 1,256 once invoked, about $0.0002 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 2026-08-30.
