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.

What it costs to keep this loaded
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 | $0.00106 | $0.01721 |
| Opus 5 | $0.00053 | $0.00860 |
| Sonnet 5 | $0.00021 | $0.00344 |
| Haiku 4.5 | $0.00011 | $0.00172 |
Grade A, and why
comparative-advantage 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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Comparative Advantage
Overview
Mutually beneficial specialization depends on relative productivity, not absolute. Even if you are better than everyone else at every task, you gain by focusing on tasks where your opportunity-cost ratio is lowest and delegating the rest. The right question is not "am I better at X than them?" but "am I better at X relative to Y compared to how they are?"
Proved by David Ricardo (1817); called "the only proposition in economics that is both true and non-obvious" by Paul Samuelson (1969).
Composes with opportunity-cost, pareto-principle, circle-of-competence, theory-of-constraints.
When to Use
- Founder time allocation across activities; team division of labor
- Build vs. buy / in-house vs. outsource decisions
- M&A decisions; international operations / supply chain design (e.g. AI-chip re-shoring, chip export controls, semiconductor vertical integration)
- Personal career or skill specialization decisions
Not when: situation is genuinely single-task (no B to trade off); transaction costs swamp any gains; alternative producer's capacity is fully constrained.
Coaching Novices (Adaptive Front Door)
- Engine mode: user has a concrete allocation decision → run The Process directly.
- Coach mode: user is unfamiliar or has no concrete case → guide step by step.
In Coach mode, respond one step at a time. Each [WAIT] is a hard stop — output only that step's question, then stop.
- One-line: the right test is not "am I better than them at this?" but "am I better at this relative to what else I could be doing?"
- Check fit: if single-task or transaction costs very high, analysis adds limited value.
- Elicit the case: what are you considering doing? What else could you do with the time? Who else could do it?
[WAIT — do not advance until user responds]
- One question at a time: what's your opportunity cost of the focal task? What's the alternative producer's OC? Where do ratios diverge? Are transaction costs material?
[WAIT — do not advance until user responds]
- Close: specialization recommendation + transaction-cost caveat + monitoring plan.
[WAIT — do not advance until user responds]
What ships with it
4 files 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.

comparative-advantage is a skill published in the GitHub repository deciqAI/knowledge-skills (10 stars, last pushed 6d ago), licensed MIT. It adds 106 tokens to every session and 1,721 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 2026-08-31.
