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 | $0.00024 | $0.00297 |
| Opus 5 | $0.00012 | $0.00148 |
| Sonnet 5 | $0.00005 | $0.00059 |
| Haiku 4.5 | $0.00002 | $0.00030 |
Grade A, and why
tradeoff-matrix-builder 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 5d 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.
What it actually says
Purpose
Quantify and structure complex technical evaluations by comparing alternatives against explicit, weighted decision criteria with rationale.
When to Use
- Choosing between frameworks, databases, libraries, or architectural patterns.
- Resolving engineering stalemates on technology selection.
- Providing objective justification for RFCs and executive presentations.
What to Analyze
- Candidate Options: 2 to 4 viable technical contenders.
- Evaluation Dimensions: Performance, developer experience, maintenance cost, ecosystem maturity, learning curve, vendor lock-in.
- Weighting: Importance score (1-5) per criterion based on project priorities.
- Scoring & Justification: Objective score (1-5) per candidate on each dimension with concrete rationale.
- Sensitivity Analysis: Which criterion flipping would change the decision?
Output Format
- Decision Summary: The recommended winner and one-line core thesis.
- Weighted Matrix (Markdown Table): Options, Weights, Scores, and Total Weighted Score.
- Criterion-by-Criterion Justification: Detailed rationale per cell.
- Risk & Mitigation for Winner: What gotchas come with the winning choice.
Avoid
- Arbitrary numbers without stated rationale.
- Biased weighting designed to force a pre-determined favorite.
What ships with it
2 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.

tradeoff-matrix-builder is a skill published in the GitHub repository codebygarv/Ai-skills (25 stars, last pushed 19d ago), licensed MIT. It adds 24 tokens to every session and 297 once invoked, about $0.0001 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.
