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 | $0.00129 | $0.02923 |
| Opus 5 | $0.00064 | $0.01461 |
| Sonnet 5 | $0.00026 | $0.00585 |
| Haiku 4.5 | $0.00013 | $0.00292 |
Grade C, and why
managing-mtga-data scanned grade C with 1 finding 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Wrangler D1 Commands
Always use --remote for staging/production. Without it, wrangler targets the local SQLite.
# Query staging
wrangler d1 execute 0147892e-82e6-413e-a0ef-52f6d8787fdf --remote \
--command "SELECT COUNT(*) FROM magic_cards WHERE is_default=1"
# Query production
wrangler d1 execute df241bb0-9b7d-48e5-a4d4-f84ebf09e6e5 --remote \
--command "SELECT COUNT(*) FROM magic_draft_ratings"
Run wrangler from the worker/ directory (it reads wrangler.toml for config). Use the database ID directly, not the binding name.
Import Pipeline
Just Targets
just update-mtga staging # Full import: all phases, all tools
just update-mtga production # Same for production
just update-mtga-retry staging # Retry from cached SQL (no CSV reprocessing)
Phases and Tools
Imports run in strict dependency order. mtga-carddb must run first — it populates magic_cards from the MTGA client database. All other tools enrich or depend on that data.
| Phase | Tool | Writes To | Pipeline Key |
|---|---|---|---|
| 0 | mtga-carddb |
magic_cards + FTS, arena_cards_gen.go |
tool='mtga-carddb', set_code='_global' |

magic_rules, magic_card_rulings + FTS |

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.

managing-mtga-data is a skill published in the GitHub repository joshsymonds/savecraft.gg (12 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 129 tokens to every session and 2,923 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
