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.
npx agentmods add instructions/tikoci/rosetta/extractiongit clone --depth 1 https://github.com/tikoci/rosettaWhat 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 | $0.00166 | $0.00166 |
| Opus 5 | $0.00083 | $0.00083 |
| Sonnet 5 | $0.00033 | $0.00033 |
| Haiku 4.5 | $0.00017 | $0.00017 |
Grade A, and why
rosetta extraction.instructions.md 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 2d 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
Extraction instruction map
The extraction surface now uses narrow rule files. Read the ones that match your change:
extractor-idempotent.instructions.mdextractor-import-side-effects.instructions.mdcommand-versions-vs-presence.instructions.mdschema-roundtrip-compat.instructions.mddata-source-naming-product-matrix.instructions.mdskill-attribution-boundary.instructions.mdgithub-api-auth.instructions.md
Keep this file as a router only. Put new extraction rules in the narrow file that actually owns them.
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.

rosetta extraction.instructions.md is an instructions file published in the GitHub repository tikoci/rosetta (43 stars, last pushed 16d ago), licensed MIT. It adds 166 tokens to every session, about $0.0008 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.
