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 | $0.00075 | $0.00268 |
| Opus 5.5 | $0.00030 | $0.00107 |
| Sonnet 5.5 | $0.00015 | $0.00054 |
| Haiku 4.5 | $0.00007 | $0.00027 |
Grade A, and why
trove-principle-encode-in-structure 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 1mo 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
Principle: Encode Lessons in Structure
When the same instruction has to be written twice, the instruction is the symptom. Encode the lesson in structure so it enforces itself.
Route by recurrence:
- One-off → a note in the moment; no structure needed.
- Recurring → a lint, a rubric criterion, a script, or a skill edit that makes the wrong thing fail loudly.
- Systemic → a principle (like this one) that shapes future design.
"I'll keep that in mind" doesn't persist across sessions or agents. A check does. This is the philosophy behind the marketplace's eval rubrics and learnings.jsonl; pairs with trove-reflect (mine a session for lessons and route each into a concrete edit).
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.

trove-principle-encode-in-structure is a skill published in the GitHub repository bravew/trove (10 stars, last pushed yesterday), licensed MIT. It adds 75 tokens to every session and 268 once invoked, about $0.0003 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 2026-09-11.
