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 | $0.00098 | $0.01105 |
| Opus 5 | $0.00049 | $0.00553 |
| Sonnet 5 | $0.00020 | $0.00221 |
| Haiku 4.5 | $0.00010 | $0.00111 |
Grade A, and why
strategy-bakeoff 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 — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Multi-Family Strategy Bakeoff
A two-layer SEARCH → CERTIFY funnel with a mandated minimum body of work. The central rule: a verdict is FORBIDDEN from the search layer. Only walk-forward certification (walk-forward-oos) can end the campaign.
Two tools, two jobs
- SEARCH layer (cheap):
backtest_portfolio,create_portfolio_variant,optimize_portfolio,systematic_sweep. It may only KILL or PROMOTE an idea into certification. It outputs "a ranked set of SEEDS" and may never issue a verdict. - CERTIFY layer (workhorse): walk-forward sweep certification on promoted seeds. Only this layer can conclude PASS / FAIL or "no deployable winner."
systematic_sweep over the deployment × structure × DTE × delta grid is mandatory in the
search layer before any neighborhood is declared dead.
The mandated minimum body
- ≥ 3 distinct mechanism families certified before any "no winner" verdict. Genuinely different mechanisms, not three tweaks of one family. Family menu (pick ≥3): (a) momentum long calls/verticals; (b) regime-switch long/flat; (c) defined-credit / short-premium (earns in flat/down tape); (d) calendar / diagonal time-spreads; (e) protective-collar or put-spread-financed longs.
- Up to 3 certification attempts per family (re-sweep from a CLEAN seed with refined
gene_intents, deeper grid, or wider validation) before a family is "exhausted." - Realistic total: ~3–9 sweep certifications, plus the incumbent certified as a seed.
- Each sweep non-trivial: ≥3
gene_intentsaxes × ≥3 values each (see sweep-reoptimization for the exact field mappings). A 1-axis or 2-value sweep does NOT qualify.
Per-family certification ledger (required)
Log this table in the run log — a family with no ledger row was NOT explored:
| Family | Seed id | get_sweep_surface ✓ | gene_intents axes | Study id | crossFoldRobustSelection key | Assembled book id | Per-fold OOS gate result | PROMOTE / KILL (reason) |
What ships with it
3 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.

strategy-bakeoff is a skill published in the GitHub repository austin-starks/Public-Portfolio-Challenge (44 stars, last pushed 3d ago), licensed MIT. It adds 98 tokens to every session and 1,105 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 2026-08-30.
