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 | $0.00037 | $0.00262 |
| Opus 5.5 | $0.00015 | $0.00105 |
| Sonnet 5.5 | $0.00007 | $0.00052 |
| Haiku 4.5 | $0.00004 | $0.00026 |
Grade A, and why
decision-tracing 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 2mo 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
Decision Tracing
Look at a decision. Figure out why it was made.
How to use
/decision-tracingApply decision-tracing analysis to any design in this conversation.
Constraints
Trace Structure
- MUST follow: Observation > Decision > Probable Reason
- "The primary font is Inter" > "They chose a geometric sans-serif" > "Data-heavy product needing maximum legibility at small sizes with neutral personality"
- MUST generate at least 5 traces per design screen
- SHOULD acknowledge uncertainty: "probable reason" not "the reason"
- NEVER state intent as fact unless you have insider knowledge
What to Trace
- Typeface selection and type system
- Color palette and color role assignments
- Layout structure and grid decisions
- Spacing and density choices
- Navigation architecture
- What's absent (what they chose NOT to include)
Anti-Patterns
- Assuming the most flattering interpretation of every decision
- Tracing only visual decisions and ignoring structural ones
- Stating reasons as facts without marking them as hypotheses
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.

decision-tracing is a skill published in the GitHub repository Dragoon0x/taste-skills (7 stars, last pushed 8mo ago), licensed MIT. It adds 37 tokens to every session and 262 once invoked, about $0.0001 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 2026-08-31.
